The storage device of the present invention will be described in detail with reference to specific embodiments.

Example 1

Referring to fig. 1 to 6c, the present embodiment provides a storage device 100, where the storage device 100 includes a body 11, a pair of guiding mechanisms 12, a first separating frame 132, a second separating frame 131, and an adjusting component 14.

The body 11 encloses a generally rectangular parallelepiped containing chamber 10 having an upper opening, the containing chamber 10 being used for storing various kinds of stored articles such as food, beverage and the like. The body 11 includes a bottom wall, a pair of first side walls 11a disposed opposite to each other, and a pair of second side walls 11b disposed opposite to each other. The bottom wall is for carrying the storage object, and a pair of first side walls 11a and a pair of second side walls 11b respectively extend vertically upward from the bottom wall.

In order to clearly express the position and direction described in the present embodiment, the direction defined by the relative positions of the pair of first side walls 11a is defined as the front-rear direction (also referred to as the longitudinal direction), and the direction defined by the relative positions of the pair of second side walls 11b is defined as the left-right direction (also referred to as the lateral direction). That is, the pair of first side walls 11a are disposed to face each other in the front-rear direction, and the pair of second side walls 11b are disposed to face each other in the left-right direction. In addition, a plane defined by the front-rear direction and the left-right direction together is defined as a horizontal plane, and a direction perpendicular to the horizontal plane is defined as a vertical direction.

Referring to fig. 1 and 2, a pair of guide mechanisms 12 are provided on a pair of second side walls 11b, respectively. The guide mechanism 12 includes a guide rod 12a, a guide 12b, and a fixing base 12c, wherein: the guide mechanism 12 is fixed on the body 11 through a fixed seat 12c, and the fixed manner between the fixed seat 12c and the body 11 can adopt threaded connection, riveting, snap connection and the like; the guide rod 12a extends in parallel with the second side wall 11b and front and rear; the guide 12b is sleeved on the guide rod 12a and can slide back and forth along the guide rod 12a, and when the guide mechanism 12 is fixed on the body 11, the guide 12b can only slide back and forth relative to the body 11.

The first partition frame 132 is accommodated in the accommodating chamber 10 and may be used to divide the accommodating chamber 10 back and forth. Specifically, the first partition frame 132 includes a partition member transversely disposed in the accommodating chamber 10 for dividing the accommodating chamber 10, a vertical surface where the partition member is disposed defines a partition surface of the first partition frame 132, and the accommodating chamber 10 is divided back and forth with the partition surface of the first partition frame 132 as a boundary. In this embodiment, the partition includes partition rails 132a, 132b provided in a long rod shape, the partition rails 132a, 132b extending left and right and being spaced apart in the vertical direction.

The first partition rack 132 further includes a pair of connecting members 132c, the connecting members 132c connecting the ends of the partition rails 132a and 132b and enclosing a rectangular frame with the partition rails 132a, 132 b.

The first partition frame 132 is slidably coupled to the body 11 back and forth by the guide mechanism 12 to adjust the size and/or number of storage partitions formed by dividing the accommodating chamber 10 back and forth. Specifically, the first separation frame 132 includes a pair of fixing portions 132d formed at both left and right ends of the first separation frame 132, each fixing portion 132d being connected to the corresponding guide 12b. When the guide 12b slides back and forth along the guide rod 12a, the first partition frame 132 slides back and forth in the accommodating chamber 10 in synchronization.

The fixing portion 132d and the guide 12b are inserted into each other. The fixing portion 132d is specifically provided in a long rod shape, and its extending direction is perpendicular to the extending direction (left-right direction) of the partition crossbars 132a, 132 b; the guide 12b includes a mounting hole 12d that mates with the fixing portion 132d, and the fixing portion 132d is insertable into the mounting hole 12d along its extending direction. When the fixing portion 132d is inserted into the mounting hole 12d, the fixing portion 132d and the mounting hole 12d are limited to each other in the left-right direction, so that the fixing portion 132d cannot move left-right relative to the guide 12 b; the pair of guide members 12b limit the first separation frame 132, so that the first separation frame 132 cannot move left and right relative to the body 11, and stability of the first separation frame 132 is enhanced.

The outer surface of each guide member 12b is abutted against the corresponding second side wall 11b, so that when the first partition frame 132 generates a movement tendency toward the left or right with respect to the body 11, one guide member 12b can limit the movement tendency toward the left of the first partition frame 132 by abutting against the corresponding second side wall 11b, and the other guide member 12b can limit the movement tendency toward the right of the first partition frame 132 by abutting against the corresponding second side wall 11 b.

In the present embodiment, the guide mechanism 12 is disposed outside the body 11 facing away from the accommodating chamber 10, specifically outside the corresponding second side wall 11 b. The inner side of each guide member 12b is respectively abutted against the corresponding second side wall 11b, so that the stability of the guide member 12b in sliding is enhanced, and the first separation frame 132 is prevented from shaking left and right relative to the body 11 in the use process.

Each of the second side walls 11b is provided with a guide groove 11c extending forward and backward, and both left and right ends of the first partition frame 132 are coupled to the guide mechanism 12 through the guide groove 11c, specifically, the fixing portion 132d is coupled to the mounting hole 12d of the guide member 12b from the accommodating chamber 10 through the guide groove 11 c.

In the present embodiment, the extending direction of the fixing portion 132d is parallel to the extending direction of the guide groove 11c, that is, the fixing portion 132d also extends along the front-rear direction, so that not only the first partition frame 132 can be prevented from shaking left and right relative to the body 11 during use, but also the fixing portion 132d can be conveniently detached from the guide member 12b, and further the first partition frame 132 can be conveniently assembled and disassembled.

Further, the guide 12b includes a first guide member 121b and a second guide member 122b provided separately, and the first guide member 121b and the second guide member 122b are detachably assembled and connected. The mounting hole 12d is disposed on the first guide member 121b, and the first guide member 121b and the second guide member 122b define a channel 12e, and the channel 12e communicates with the mounting hole 12 d. When the first guide member 121b and the second guide member 122b are separated, the fixing portion 132d may be inserted into the mounting hole 12d from between the first guide member 121b and the second guide member 122b, and then the first guide member 121b and the second guide member 122b are assembled and connected, so that the second guide member 122b limits the fixing portion 132d, and prevents the fixing portion 132d from being separated from the mounting hole 12 d.

Referring to fig. 1 to 3, the second partition frame 131 is accommodated in the accommodating cavity 10 and can be used for dividing the accommodating cavity 10. In the present embodiment, the second partition frame 131 is rotatably connected to the first partition frame 132 about the vertical axis t through the adjustment assembly 14, and the storage device 100 has a stacked state (refer to fig. 1) and an unfolded state (refer to fig. 3) according to the positional relationship of the second partition frame 131 and the first partition frame 132. By providing the second partition frame 131 rotatably coupled to the first partition frame 132, the number of storage partitions formed by dividing the accommodating chamber 10 can be adjusted, increasing flexibility in dividing the accommodating chamber 10.

The second partition frame 131 includes a partition body that can be used to divide the accommodating chamber 10, and a vertical plane in which the partition body is located defines a partition surface of the second partition frame 131. The lateral width of the receiving chamber 10 (i.e., the distance between the pair of second side walls 11 b) is greater than the longitudinal width of the receiving chamber 10 (i.e., the distance between the pair of first side walls 11 a), and accordingly, the width of the partition surface of the first partition frame 132 is greater than the width of the partition surface of the second partition frame 131, i.e., the length of the partition is greater than the length of the partition body.

In this embodiment, the separator includes separating longitudinal bars 131a, 131b provided in a long bar shape, and the separating longitudinal bars 131a, 131b are parallel to each other and spaced apart from each other in the vertical direction.

Referring to fig. 1, when the storage device 100 is in the stacked state, the separation surface of the second separation frame 131 is coplanar with the separation surface of the first separation frame 132, and the separation longitudinal bars 131a, 131b and the separation cross bars 132a, 132b extend in the left-right direction and are located in the same vertical plane, so that the occupied space of the second separation frame 131 can be reduced when not in use, and the cleanliness and the aesthetic quality can be increased; referring to fig. 3, when the storage device 100 is in the unfolded state, the second partition frame 131 and the first partition frame 132 are disposed in a crisscross manner, the accommodating cavity 10 may be divided front and back by using the partition surface of the first partition frame 132 as a boundary, and the accommodating cavity 10 may be divided left and right by using the partition surface of the second partition frame 131 as a boundary, at this time, the partition surface of the second partition frame 131 and the partition surface of the first partition frame 132 have a non-zero included angle, in this embodiment, at this time, the partition surface of the second partition frame 131 is perpendicular to the partition surface of the first partition frame 132, specifically, the partition longitudinal bars 131a and 131b extend in the front-rear direction, the partition transverse bars 132a and 132b extend in the left-right direction, and the partition longitudinal bars 131a and 131b are perpendicular to the partition transverse bars 132a and 132b.

Further, the partition further includes a glass partition 133a, and the partition 133a may be selectively assembled between the partition rails 132a and 132b by a user through the first and second fixtures 133b and 133 e. Wherein the spacer 133a is assembled to the connector 132c by the first fixing member 133b and detachably coupled to the adjustment assembly 14 by the second fixing member 133 e. By providing the partition plate 133a, the stored articles in the storage areas on the front and rear sides of the first separator 132 are not contacted, so that the odor tainting is avoided, and the cross sliding of the stored articles from between the separator rail 132a and the separator rail 132b is avoided. Of course, in alternative embodiments, the spacer 133a may not just be located between the divider rail 132a and the divider rail 132b, but may extend partially upward above the divider rail 132a and/or partially downward below the divider rail 132 b.

In the vertical direction, the dividing vertical bars 131a and the dividing vertical bars 131b are disposed adjacently, and the dividing vertical bars 131a are always higher than the upper boundary of the dividing member (i.e., the dividing cross bar 132a in the present embodiment), and the dividing vertical bars 131b are always lower than the lower boundary of the dividing member (i.e., the dividing cross bar 132b in the present embodiment). The partition longitudinal bars 131a, the partition cross bars 132a, the partition plates 133a, the partition cross bars 132b, and the partition longitudinal bars 131b are sequentially arranged in the vertical direction. In this way, the second spacer 131 does not interfere with the spacer 133a when the storage device 100 is in the stacked state.

Further, the second partition frame 131 may also be slidably connected to the first partition frame 132 by the adjusting assembly 14, that is, the second partition frame 131 may be both slidable and rotatable about the vertical axis t with respect to the first partition frame 132, thereby adjusting the number/size of the storage partitions divided into the accommodating chambers 10 as needed.

Wherein, the second partition frame 131 is slidably connected to the first partition frame 132 through the adjusting assembly 14, which has various implementations: first, the first partition frame 132 is non-slidably connected to the adjustment assembly 14, and the second partition frame 131 is slidably connected to the adjustment assembly 14, so that the size/number of storage partitions formed by dividing the accommodating chamber 10 back and forth by the first partition frame 132 can be adjusted; second, the first partition frame 132 is slidably connected to the adjustment assembly 14, and the second partition frame 131 is non-slidably connected to the adjustment assembly 14, so that the size/number of storage partitions formed by dividing the accommodating chamber 10 left and right by the second partition frame 131 can be adjusted; third, as in the present embodiment, the first partition frame 132 is slidably connected to the adjusting assembly 14, and the second partition frame 131 is also slidably connected to the adjusting assembly 14, so that the size/number of the storage partitions formed by dividing the housing chamber 10 back and forth by the first partition frame 132 and the storage partitions formed by dividing the second partition frame 131 left and right can be adjusted, and the flexibility is improved.

The specific structure of the adjustment assembly 14 is described in detail below with reference to fig. 4 a-5. In the present embodiment, the adjustment assembly 14 is provided in a cylindrical configuration that is mirror symmetrical along a horizontal plane q, although the shape and configuration are not limited to this embodiment in alternative embodiments.

The adjustment assembly 14 includes a first adjustment mechanism and a second adjustment mechanism. The first adjusting mechanism is coupled with one of the first and second partition frames 132 and 131, and the second adjusting mechanism is coupled with the other of the first and second partition frames 132 and 131. In the present embodiment, the first adjusting mechanism is coupled to the first partition frame 132, and two first adjusting mechanisms 142a coupled to the partition rail 132a and the first adjusting mechanism 142b coupled to the partition rail 132b are provided; the second adjusting mechanism is coupled with the second partition frame 131, and two second adjusting mechanisms 141a coupled with the partition longitudinal bar 131a and 141b coupled with the partition longitudinal bar 131b are also provided; the first adjustment mechanism 142a mates with the second adjustment mechanism 141a, and the first adjustment mechanism 142b mates with the second adjustment mechanism 141 b.

The first adjustment mechanism 142a includes a third member 43a, a fourth member 44a, and a first channel 145a. Wherein the third member 43a comprises two hooks 434a and a groove 433a; the fourth member 44a includes two card slots 441a and a groove 442a; the two hooks 434a are in one-to-one correspondence with the two clamping grooves 441a and are in snap fit connection, so that the third member 43a and the fourth member 44a are assembled and connected with each other; the first channel 145a is formed between the third member 43a and the fourth member 44a, and is specifically defined by the recess 433a and the recess 442a, thereby facilitating assembly of the first adjustment mechanism 142a with the partition rail 132 a. The first channel 145a allows the divider beam 132a to pass through to slide the first adjustment mechanism 142a along the divider beam 132 a.

Similarly, the first adjusting mechanism 142b is assembled with the set of dividing rails 132b, and the specific structure thereof is referred to the first adjusting mechanism 142a and will not be described herein. The first channels 145a and 145b are parallel and the adjustment assembly 14 is slidably coupled to the first spacer 132 side-to-side.

The second adjustment mechanism 141a includes a first member 41a, a second member 42a, and a second channel 144a. Wherein the first member 41a comprises two hooks 411a and a groove 412a; the second member 42a includes two card slots 421a and a groove 422a; the two hooks 411a are in one-to-one correspondence with the two clamping grooves 421a and are in snap fit connection, so that the first member 41a and the second member 42a are assembled and connected with each other; the second channel 144a is formed between the first member 41a and the second member 42a, and is specifically defined by the recess 422a and the recess 412a, thereby facilitating the assembly and coupling of the second adjustment mechanism 141a with the partition rail 131 a. The second channel 144a allows the partition longitudinal bar 131a to pass therethrough to slide the second adjustment mechanism 141a along the partition longitudinal bar 131 a.

Similarly, the second adjusting mechanism 141b is assembled with the partition longitudinal bar 131b, and the specific structure thereof is referred to the second adjusting mechanism 141a and will not be described herein. The second channel 144a and the second channel 144b are parallel and the adjustment assembly 14 is slidingly coupled to the second spacer 131.

Further, the first adjustment mechanism 142a includes a mating post 432a, and the second adjustment mechanism 141a includes a mating hole that mates with the mating post 432 a; the mating post 432a and the mating hole of the second adjusting mechanism 141a can be mated in a vertical direction, and the mating post 432a and the mating hole of the second adjusting mechanism 141a have cylindrical mating surfaces that are matched with each other, so that the first adjusting mechanism 142a and the second adjusting mechanism 141a are mated and can rotate around a vertical axis t relative to each other, and in this embodiment (taking the body 11 as a reference), the second adjusting mechanism 141a rotates around the vertical axis t. Likewise, the second adjustment mechanism 141b includes a mating hole 424b, and the first adjustment mechanism 142b includes a mating post that mates with the mating hole 424 b; the mating hole 424b is mated with the mating post of the first adjusting mechanism 142b in a vertical direction, and the mating hole and the mating post have cylindrical mating surfaces that are matched with each other, so that the first adjusting mechanism 142b and the second adjusting mechanism 141b are mated and rotatable relative to each other about a vertical axis t, and in this embodiment (with reference to the body 11) the second adjusting mechanism 141b rotates about the vertical axis t.

And, when the coupling posts 432a and the coupling holes of the second adjustment mechanism 141a are coupled, they are limited to each other so that the relative displacement of the first adjustment mechanism 142a and the second adjustment mechanism 141a in the horizontal direction is limited, thereby preventing shaking. Also, when the coupling hole 424b and the coupling post of the first adjustment mechanism 142b are coupled to each other, they are limited to each other, so that the relative displacement of the first adjustment mechanism 142b and the second adjustment mechanism 141b in the horizontal direction is limited, thereby preventing rattling.

In this way, the first and second dividing frames 132 and 131 are rotated about the vertical axis t relative to each other by the relative rotation of the first and second adjusting mechanisms 142a and 142b and 141a and 141b, so that the storage device 100 is switched between the stacked state and the unfolded state.

Specifically, the adjustment assembly 14 further includes a cam structure formed between the first and second adjustment mechanisms. In the present embodiment, the number of the cam structures is set to two, that is, the cam structure 143a formed between the first adjustment mechanism 142a and the second adjustment mechanism 141a, and the cam structure 143b formed between the first adjustment mechanism 142b and the second adjustment mechanism 141 b. Of course, in a variant embodiment, only one of the cam structures 143a and 143b may be provided.

Taking the cam structure 143a as an example, a specific structure of the cam structure will be described (a specific structure of the cam structure 143b refers to the cam structure 143a, and will not be described again). The cam structure 143a includes a first concave-convex curved surface 431a formed in the entire circumferential wave shape of the upper end surface of the first adjustment mechanism 142a and a second concave-convex curved surface 423a formed in the entire circumferential wave shape of the lower end surface of the second adjustment mechanism 141a, and the first concave-convex curved surface 431a and the second concave-convex curved surface 423a are adapted; and when the first adjustment mechanism 142a and the second adjustment mechanism 141a rotate around the vertical axis t relative to each other, the second concave-convex curved surface 423a and the first concave-convex curved surface 431a are in abutting fit with each other, so that the first adjustment mechanism 142a and the second adjustment mechanism 141a do reciprocating jump movements away from or close to each other in the vertical direction.

The cam structure 143a has at least two lowest point engagement positions (see fig. 4a and 4 c) where the second concave-convex curved surface 423a and the first concave-convex curved surface 431a are in concave-convex engagement with each other, and a highest point abutment position (see fig. 4 b) where the second concave-convex curved surface 423a and the first concave-convex curved surface 431a are in convex abutment with each other. When the cam structure 143a moves from the lowest point engagement position to the highest point abutment position, the first adjustment mechanism 142a and the second adjustment mechanism 141a are vertically away from each other; when the cam structure 143a moves from the highest point abutment position to the lowest point engagement position, the first adjustment mechanism 142a and the second adjustment mechanism 141a approach each other in the vertical direction.

When the second partition frame 131 rotates about the vertical axis t relative to the first partition frame 132, taking a process of changing the storage device 100 from the stacked state to the unfolded state (a process of changing the storage device 100 from the unfolded state to the stacked state is opposite to the process of changing the storage device 100 from the unfolded state to the stacked state, and is not repeated as follows) as an example:

Referring to fig. 4a, when the storage device 100 is in the stacked state, the adjusting assembly 14 is in the first engaged state, where the first channels 145a, 145b and the second channels 144a, 144b are parallel, and accordingly, the separation surface of the first separation frame 132 is parallel to the separation surface of the second separation frame 131, and the cam structures 143a, 143b are both in the lowest point engaged position;

Referring to fig. 4b, when the storage device 100 is switched from the stacked state to the deployed state, during the process of changing the adjustment assembly 14 from the first engagement state to the critical state, the cam structures 143a, 143b each move from the lowest point engagement position to the highest point abutment position, the first adjustment mechanism 142a and the second adjustment mechanism 141a are vertically apart from each other, and the first adjustment mechanism 142b and the second adjustment mechanism 141b are vertically apart from each other; until the adjustment assembly 14 is in the critical state, both cam structures 143a, 143b are in the highest point abutment position; then, during the transition of the adjustment assembly 14 from the critical state to the second engagement state, the first adjustment mechanism 142a and the second adjustment mechanism 141a are brought close to each other in the vertical direction, and the first adjustment mechanism 142b and the second adjustment mechanism 141b are brought close to each other in the vertical direction;

Referring to fig. 4c, when the storage device 100 is in the unfolded state, the adjusting assembly 14 is in the second engaged state, where the first channels 145a, 145b and the second channels 144a, 144b are perpendicular, and accordingly, the separation surface of the first separation frame 132 is perpendicular to the separation surface of the second separation frame 131, and the cam structures 143a, 143b are in the other lowest point engaged position.

Further, the cam structures 143a, 143b are each configured as a circumferential quarter-turn structure, i.e. when the cam structures 143a, 143b are shifted between adjacent two of said nadir engagement positions, the first adjustment mechanism 142a is rotated 90 ° relative to the second adjustment mechanism 141a about the vertical axis t, and the first adjustment mechanism 142b is rotated 90 ° relative to the second adjustment mechanism 141b about the vertical axis t. Further, the second partition frame 131 is rotated 90 ° about the vertical axis t with respect to the first partition frame 132 to switch the storage device 100 between the stacked state and the unfolded state, completing one inversion cycle.

Meanwhile, when the cam structures 143a, 143b are shifted between the lowest point engagement position and the highest point abutment position, the first adjustment mechanism 142a and the second adjustment mechanism 141a are rotated 45 ° about the vertical axis t with respect to each other, and the first adjustment mechanism 142b and the second adjustment mechanism 141b are rotated 45 ° about the vertical axis t with respect to each other.

Further, when the cam structures 143a, 143b are not at the lowest point engagement position, the adjustment assembly 14 is always subjected to an elastic driving force that drives the cam structures 143a, 143b to the lowest point engagement position, that is, the elastic driving force drives the first adjustment mechanism 142a and the second adjustment mechanism 141a to have a tendency to approach each other in the vertical direction and the first adjustment mechanism 142b and the second adjustment mechanism 141b to have a tendency to approach each other in the vertical direction.

In this embodiment, the elastic driving force is provided by the second spacer 131. Specifically, the second spacer 131 is made of a rigid material, and further includes a pair of connecting rods 131c connecting the ends of the spacer vertical rods 131a and the ends of the spacer vertical rods 131 b; the fourth member 44a and the fourth member 44b are integrally formed, the fourth member 44a being provided as an upper half of the structural member 44, and the fourth member 44b being provided as a lower half of the member 44, so that the first adjustment mechanisms 142a, 142b are fixedly connected in the vertical direction. When the cam structures 143a, 143b are in the lowest point engagement position, the second spacer 131 has no elastic deformation, which separates the longitudinal bars 131a, 131b from each other in parallel and with an initial spacing; when the cam structures 143a, 143b are not at the lowest point engagement position (including being between the lowest point engagement position and the highest point abutment position and being at the highest point abutment position), the local spacing between the separating longitudinal bars 131a, 131b near the adjusting assembly 14 is greater than the initial spacing under the driving of the second adjusting mechanisms 141a, 141b, and the end maintains the initial spacing under the pulling of the connecting bar 131c, so that the second separating frame 131 is elastically deformed, and the elastically deformed second separating frame 131 is applied to the adjusting assembly 14 by the elastic driving force.

In this way, the storage device 100 switches between the stacked state and the expanded state during one flip cycle: under the action of artificial external force, the second separation frame 131 rotates around the vertical axis t relative to the first separation frame 132, the adjusting component 14 changes from the first meshing state to the critical state (or from the second meshing state to the critical state), the cam structures 143a and 143b move from the lowest point meshing position to the highest point abutting position, and the second adjusting mechanisms 141a and 141b are away from each other along the vertical direction to drive the second separation frame 131 to elastically deform; when the adjusting assembly 14 reaches the critical state, the cam structures 143a, 143b are both at the highest point abutment position, and the elastic deformation of the second partition frame 131 is maximized; the second adjustment mechanisms 141a, 141b approach each other in the vertical direction beyond the critical state by the elastic restoring force of the second partition frame 131, and the adjustment assembly 14 is changed from the critical state to the second engagement state (or from the critical state to the first engagement state), thereby changing the storage device 100 from the stacked state to the expanded state (or from the expanded state to the stacked state).

Of course, in a variant embodiment, the storage device 100 may further include an elastic member that provides the elastic driving force, where the elastic member is disposed between the first adjusting mechanism and the second adjusting mechanism, and the elastic member is elastically deformed when the cam structure is not at the lowest point engagement position.

Further, the connection bars 131c are disposed non-coplanar with the partition longitudinal bars 131a, 131b, and a pair of connection bars 131c are abutted against the partition rails 132a and 132b and located at front and rear sides of the first partition frame 132, respectively, when the storage device 100 is in the stacked state.

Compared with the prior art, the storage device 100 of the present embodiment can adjust the number/size of the storage partitions formed by dividing the accommodating cavity 10 as required, for example, by moving the first partition frame 132 and/or the second partition frame 131 to form a zero partition as shown in fig. 6a, a two partition as shown in fig. 6b or fig. 1, a four partition as shown in fig. 3, or by removing and replacing the second partition frame 131 to form a three partition as shown in fig. 6 c; the first separation frame 132 is convenient to disassemble and assemble, and has good stability in the use process; the first partition frame 132 can prevent the storage partition from falling off.

Of course, in a variant embodiment, the first adjusting mechanism may be provided as one, and the upper and lower ends of the first adjusting mechanism are respectively connected with the second adjusting mechanism in a matching way; or the two second adjusting mechanisms are fixedly connected in the vertical direction, the two first adjusting mechanisms are arranged in a split mode, and when the adjusting assembly changes from a first meshing state to a critical state, the two first adjusting mechanisms move relatively close to each other along the vertical direction. Such variations do not depart from the gist of the invention.

Example 2

Referring to fig. 7-9 c, the present embodiment provides a storage device 200, where the storage device 200 includes a body 21, a pair of guiding mechanisms 22, a first separating frame 232, a second separating frame 231, and an adjusting assembly 24.

The body 21 encloses a generally rectangular parallelepiped containing chamber 20 having an upper opening, the containing chamber 20 being used for storing various kinds of stored articles such as food, beverage and the like. The body 21 specifically includes a bottom wall, a pair of first side walls 21a disposed opposite to each other, and a pair of second side walls 21b disposed opposite to each other. The bottom wall is for carrying the storage object, and a pair of first side walls 21a and a pair of second side walls 21b respectively extend vertically upward from the bottom wall.

In order to clearly express the position and direction described in the present embodiment, the direction defined by the relative positions of the pair of first side walls 21a is defined as the front-rear direction (also referred to as the longitudinal direction), and the direction defined by the relative positions of the pair of second side walls 21b is defined as the left-right direction (also referred to as the lateral direction). That is, the pair of first side walls 21a are disposed to face each other in the front-rear direction, and the pair of second side walls 21b are disposed to face each other in the left-right direction. In addition, a plane defined by the front-rear direction and the left-right direction together is defined as a horizontal plane, and a direction perpendicular to the horizontal plane is defined as a vertical direction.

A pair of guide mechanisms 22 are provided on the pair of second side walls 21b, respectively, that is, one guide mechanism 22 is provided on each of the second side walls 21 b. The guide mechanism 22 specifically includes a plate body 22a, a guide portion 22b, and a mounting hole 22c. The guide portion 22b and the plate body 22a enclose a U-shaped slot with a downward opening, the guide mechanism 22 is hung and fastened on the upper end surface of the second side wall 21b through the U-shaped slot, and the guide mechanism 22 can slide back and forth along the upper end surface of the second side wall 21b, so that the guide mechanism 22 and the first separation frame 232 can be conveniently disassembled or assembled from the accommodating cavity 10. When the guide mechanism 22 is engaged with the upper end surface of the second side wall 21b, the relative movement between the guide mechanism 22 and the second side wall 21b in the left-right direction is restricted.

The first partition frame 232 is accommodated in the accommodating chamber 20 and may be used to divide the accommodating chamber 20 back and forth. Specifically, the first partition frame 232 includes a partition member, which is horizontally disposed in the accommodating cavity 20 to divide the accommodating cavity 20, and a vertical surface where the partition member is located defines a partition surface of the first partition frame 232, and the accommodating cavity 20 is divided front and back by using the partition surface of the first partition frame 232 as a boundary. In this embodiment, the partition includes partition rails 232a, 232b provided in a long rod shape, and the partition rails 232a, 232b extend left and right and are spaced apart in the vertical direction.

The first partition frame 232 is slidably connected to the body 21 along the front-rear direction by the guide mechanism 22, and the size and/or the number of the storage partitions formed by dividing the accommodating cavity 20 front and rear can be adjusted by sliding the first partition frame 232 so as to adapt to diversified requirements of different storage objects.

Specifically, the first partition frame 232 includes fixing portions 232d formed at both left and right ends of the first partition frame 232, the fixing portions 232d being coupled into the mounting holes 22c of the guide mechanism 22 such that the first partition frame 232 is slidably disposed in the accommodating chamber 20 back and forth by the guide mechanism 22. That is, when the guide mechanism 22 slides back and forth, the first partition frame 232 slides in the accommodating chamber 20 in synchronization.

The fixing portion 232d extends in the left-right direction and is insertable into the mounting hole 22c in the left-right direction. When the fixing portion 232d is inserted and fitted to the mounting hole 22c and the guide mechanism 22 is fastened on the second side wall 21b, the guide mechanism 22 cannot move left and right relative to the body 21, and the fixing portion 232d and the mounting hole 22c are limited in the left and right direction, so that the first partition frame 232 cannot move left and right relative to the guide mechanism 22, and the first partition frame 232 cannot move left and right relative to the body 21, thereby enhancing the stability of the first partition frame 232.

The second division frame 231 is accommodated in the accommodating chamber 20 and may be used to divide the accommodating chamber 20 left and right. In the present embodiment, the second partition frame 231 is rotatably connected to the first partition frame 232 about the vertical axis t1 by the adjustment assembly 24, and the storage device 200 has a stacked state (refer to fig. 7) and an unfolded state according to the positional relationship of the second partition frame 231 and the first partition frame 232. This allows the number of storage compartments formed by the division of the receiving chamber 20 to be adjusted as required, increasing the flexibility of the division of the receiving chamber 20.

The second division frame 231 includes a division body that can be used to divide the accommodating chamber 20, and a vertical plane in which the division body is located defines a division surface of the second division frame 231. The lateral width of the receiving chamber 20 (i.e., the interval between the pair of second side walls 21 b) is greater than the longitudinal width of the receiving chamber 20 (i.e., the interval between the pair of first side walls 21 a), and accordingly, the width of the partition surface of the first partition frame 232 is greater than the width of the partition surface of the second partition frame 231, i.e., the length of the partition is greater than the length of the partition body.

In this embodiment, the separator includes separating longitudinal bars 231a, 231b provided in a long bar shape, and the separating longitudinal bars 231a, 231b are parallel to each other and spaced apart from each other in a vertical direction.

Referring to fig. 7, when the storage device 200 is in the stacked state, the separation surface of the second separation frame 231 is coplanar with the separation surface of the first separation frame 232, the separation longitudinal bars 231a, 231b and the separation cross bars 232a, 232b all extend in the left-right direction and are located in the same vertical plane, and the separation cross bars 232a, the separation longitudinal bars 231b and the separation cross bars 232b are sequentially arranged in the vertical direction; when the storage device 200 is in the unfolded state, the second partition frame 231 is disposed crosswise to the first partition frame 232, the accommodating cavity 20 may be divided back and forth with the partition surface of the first partition frame 232 as a boundary, and the accommodating cavity 20 may be divided left and right with the partition surface of the second partition frame 231 as a boundary, where the partition surface of the second partition frame 231 and the partition surface of the first partition frame 232 have a non-zero included angle, in this embodiment, the partition surface of the second partition frame 231 is perpendicular to the partition surface of the first partition frame 232, specifically, the partition longitudinal bars 231a, 231b extend in the front-rear direction, the partition cross bars 232a, 232b extend in the left-right direction, and the partition longitudinal bars 231a, 231b are perpendicular to the partition cross bars 232a, 232b.

The second separation frame 231 further includes a pair of connection bars 231c. The connecting rod 231c connects the end of the partition vertical bar 231a and the end of the partition vertical bar 231b, is coplanar with the partition vertical bars 231a, 231b, and encloses a rectangular frame with the partition vertical bars 231a, 231 b.

Further, the second partition frame 231 may also be slidably connected to the first partition frame 232 through the adjusting assembly 24, that is, the second partition frame 231 may be both slidable and rotatable about the vertical axis t1 with respect to the first partition frame 232 to adjust the number/size of the storage partitions divided by the accommodating chamber 20.

The second partition frame 231 is slidably connected to the first partition frame 232 through the adjusting assembly 24, which has various implementations: first, the first partition frame 232 is non-slidably coupled to the adjustment assembly 24, and the second partition frame 231 is slidably coupled to the adjustment assembly 24, so that the size/number of storage partitions formed by dividing the accommodating chamber 20 back and forth by the first partition frame 232 can be adjusted; second, the first partition frame 232 is slidably connected to the adjustment assembly 24, and the second partition frame 231 is non-slidably connected to the adjustment assembly 24, so that the size/number of storage partitions formed by dividing the accommodating chamber 20 left and right by the second partition frame 231 can be adjusted; third, as in the present embodiment, the first partition frame 232 is slidably connected to the adjusting assembly 24, and the second partition frame 231 is also slidably connected to the adjusting assembly 24, so that the size/number of the storage partitions formed by dividing the housing chamber 20 back and forth by the first partition frame 232 and the storage partitions formed by dividing the second partition frame 231 left and right can be adjusted, with higher flexibility.

The specific structure of the adjusting assembly 24 in this embodiment is the same as that of the adjusting assembly 14 in embodiment 1, and the details are not repeated, but only the matching relationship between the adjusting assembly 24 and the first and second separating frames 232, 231 is the difference, which will be described in detail below.

The adjustment assembly 24 is arranged in a cylindrical configuration that is mirror symmetrical along a horizontal plane q'.

The adjustment assembly 24 includes a second adjustment mechanism coupled with the first spacer 232 and a first adjustment mechanism coupled with the second spacer 231. In the present embodiment, the second adjusting mechanisms are provided in two, that is, a second adjusting mechanism 241a (the specific structure of which refers to the second adjusting mechanism 141a of embodiment 1) coupled with the partition rail 232a and a second adjusting mechanism 241b (the specific structure of which refers to the second adjusting mechanism 141b of embodiment 1) coupled with the partition rail 232 b; the first adjusting mechanisms are also provided in two, namely, a first adjusting mechanism 242a (the specific structure of which refers to the first adjusting mechanism 142a of embodiment 1) which is coupled with the partition longitudinal bar 231a and a first adjusting mechanism 242b (the specific structure of which refers to the first adjusting mechanism 142b of embodiment 1) which is coupled with the partition longitudinal bar 231 b; the first adjustment mechanism 242a mates with the second adjustment mechanism 241a and the first adjustment mechanism 242b mates with the second adjustment mechanism 241 b.

The first adjustment mechanism 242a includes a first passage 245a through which the partition longitudinal bar 231a passes, the first adjustment mechanism 242a sliding along the partition longitudinal bar 231a when the first adjustment mechanism 242a is assembled with the partition longitudinal bar 231 a; similarly, the first adjustment mechanism 242b includes a first passage 245b through which the partition rail 231b passes, and the first adjustment mechanism 242b slides along the partition rail 231b when the first adjustment mechanism 242b is assembled with the partition rail 231 b. The first passages 245a and 245b are parallel, and the adjustment assembly 24 is slidably coupled to the second separator frame 231.

The second adjustment mechanism 241a includes a second passage 244a through which the divider crossbar 232a passes, the second adjustment mechanism 241a sliding along the divider crossbar 232a when the second adjustment mechanism 241a is assembled with the set of divider crossbars 232 a; likewise, the second adjustment mechanism 241b includes a second passage 244b through which the divider crossbar 232b passes, the second adjustment mechanism 241b sliding along the divider crossbar 232b when the second adjustment mechanism 241b is assembled with the set of divider crossbars 232 b. The second passage 244a and the second passage 244b are parallel, and the adjustment assembly 24 is slidably coupled to the first spacer 232 side to side.

Further, the first adjusting mechanism 242a and the second adjusting mechanism 241a are mated and rotatable relative to each other about the vertical axis t1, and in this embodiment (with reference to the body 21), the first adjusting mechanism 242a rotates about the vertical axis t1. Similarly, the first adjustment mechanism 242b and the second adjustment mechanism 241b are coupled to each other and are rotatable relative to each other about the vertical axis t1, and in this embodiment (with reference to the body 21) the first adjustment mechanism 242b rotates about the vertical axis t1.

Specifically, the adjustment assembly 24 further includes a cam structure formed between the first and second adjustment mechanisms. In the present embodiment, the number of the cam structures is set to two, that is, the cam structure 243a formed between the first adjustment mechanism 242a and the second adjustment mechanism 241a, and the cam structure 243b formed between the first adjustment mechanism 242b and the second adjustment mechanism 241 b. Of course, in alternative embodiments, only one of the cam structures 243a and 243b may be provided.

Taking the cam structure 243a as an example, a specific structure of the cam structure will be described (the specific structure of the cam structure 243b refers to the cam structure 243a, and will not be described again). The cam structure 243a includes a first concave-convex curved surface 431a 'formed on the upper end surface of the first adjusting mechanism 242a and a second concave-convex curved surface 423a' formed on the lower end surface of the second adjusting mechanism 241a, the first concave-convex curved surface 431a 'and the second concave-convex curved surface 423a' being adapted; and when the first adjusting mechanism 242a and the second adjusting mechanism 241a rotate around the vertical axis t1 relative to each other, the second concave-convex curved surface 423a 'and the first concave-convex curved surface 431a' are in abutting fit with each other, so that the first adjusting mechanism 242a and the second adjusting mechanism 241a do reciprocating jump motion away from or close to each other along the vertical direction.

The cam structure 243a has at least two lowest point engagement positions (see fig. 9a and 9 c) where the second concave-convex curved surface 423a 'and the first concave-convex curved surface 431a' are in concave-convex engagement with each other, and a highest point abutment position (see fig. 9 b) where the second concave-convex curved surface 423a 'and the first concave-convex curved surface 431a' are in convex abutment with each other. When the cam structure 243a moves from the lowest point engagement position to the highest point abutment position, the first adjustment mechanism 242a and the second adjustment mechanism 241a are vertically away from each other; when the cam structure 243a moves from the highest point abutment position to the lowest point engagement position, the first adjustment mechanism 242a and the second adjustment mechanism 241a approach each other in the vertical direction.

When the second separator 231 rotates about the vertical axis t1 relative to the first separator 232, taking a process of changing the storage device 200 from the stacked state to the unfolded state (a process of changing the storage device 200 from the unfolded state to the stacked state is opposite to the process of changing the storage device 200 from the unfolded state to the stacked state, and is not repeated as an example):

Referring to fig. 9a, when the storage device 200 is in the stacked state, the adjusting assembly 24 is in the first engaged state, where the first passages 245a, 245b and the second passages 244a, 244b are parallel, and accordingly, the partition surface of the first partition frame 232 is parallel to the partition surface of the second partition frame 231, and the cam structures 243a, 243b are both in the lowest point engaged position;

Referring to fig. 9b, when the storage device 200 is switched from the stacked state to the deployed state, during the process of changing the adjustment assembly 24 from the first engagement state to the critical state, the cam structures 243a, 243b each move from the lowest point engagement position to the highest point abutment position, the first adjustment mechanism 242a and the second adjustment mechanism 241a are vertically apart from each other, and the first adjustment mechanism 242b and the second adjustment mechanism 241b are vertically apart from each other; until the adjustment assembly 24 is in the critical state, both cam structures 243a, 243b are in the highest point abutment position; then, during the transition of the adjustment assembly 24 from the critical state to the second engagement state, the first adjustment mechanism 242a and the second adjustment mechanism 241a are brought close to each other in the vertical direction, and the first adjustment mechanism 242b and the second adjustment mechanism 241b are brought close to each other in the vertical direction;

referring to fig. 9c, when the storage device 200 is in the unfolded state, the adjusting assembly 24 is in the second engaged state, and at this time, the first passages 245a, 245b and the second passages 244a, 244b are perpendicular, and correspondingly, the separating surface of the first separating frame 232 is perpendicular to the separating surface of the second separating frame 231, and the cam structures 243a, 243b are both in the other lowest engaging position.

Further, the cam structures 243a, 243b are each configured as a circumferential quarter-divided structure, that is, when the cam structures 243a, 243b are shifted between the adjacent two of the lowest point engagement positions, the first adjustment mechanism 242a and the second adjustment mechanism 241a are rotated by 90 ° about the vertical axis t1, and the first adjustment mechanism 242b and the second adjustment mechanism 241b are rotated by 90 ° about the vertical axis t1. Further, the second separator 231 is rotated 90 ° about the vertical axis t1 with respect to the first separator 232, so that the storage device 200 is switched between the stacked state and the unfolded state, completing one inversion cycle.

Meanwhile, when the cam structures 243a, 243b are shifted between the lowest point engagement position and the highest point abutment position, the first adjustment mechanism 242a and the second adjustment mechanism 241a are rotated 45 ° about the vertical axis t1, and the first adjustment mechanism 242b and the second adjustment mechanism 241b are rotated 45 ° about the vertical axis t 1.

Further, when the cam structures 243a, 243b are not at the lowest point engagement position, the adjustment assembly 24 is always subjected to an elastic driving force that drives the cam structures 243a, 243b to the lowest point engagement position, that is, the elastic driving force drives the first adjustment mechanism 242a and the second adjustment mechanism 241a to have a tendency to approach each other in the vertical direction and the first adjustment mechanism 242b and the second adjustment mechanism 241b to have a tendency to approach each other in the vertical direction.

In this embodiment, the elastic driving force is provided by the first spacer 232. Specifically, the first partition frame 232 is made of a rigid material, and further includes a pair of connecting members 232c connecting the end portions of the partition cross bars 232a and the end portions of the partition cross bars 232b, where the connecting members 232c and the partition cross bars 232a and 232b together enclose a rectangular frame; the first adjusting mechanisms 242a, 242b are fixedly connected in the vertical direction. When the cam structures 243a, 243b are in the lowest point engagement position, the first spacer 232 has no elastic deformation, and the spacer rails 232a, 232b thereof are parallel to each other and have an initial spacing; when the cam structures 243a, 243b are not at the lowest point engagement position (including being between the lowest point engagement position and the highest point abutment position and being at the highest point abutment position), the local spacing between the separating crossbars 232a, 232b near the adjusting assembly 24 is greater than the initial spacing under the driving of the second adjusting mechanisms 241a, 241b, and the end maintains the initial spacing under the pulling of the connecting piece 232c, so that the first separating frame 232 has elastic deformation, and the elastically deformed first separating frame 232 applies the elastic driving force to the adjusting assembly 24.

In this way, the storage device 200 switches between the stacked state and the expanded state during one flip cycle: under the action of artificial external force, the second separation frame 231 rotates around the vertical axis t1 relative to the first separation frame 232, the adjusting component 24 changes from the first meshing state to the critical state (or from the second meshing state to the critical state), the cam structures 243a and 243b move from the lowest point meshing position to the highest point abutting position, and the second adjusting mechanisms 241a and 241b are separated from each other along the vertical direction to drive the first separation frame 232 to elastically deform; when the adjusting assembly 24 reaches the critical state, the cam structures 243a and 243b are both at the highest point abutment positions, and the elastic deformation of the first partition frame 232 is maximized; beyond the critical state, the second adjustment mechanisms 241a, 241b approach each other in the vertical direction by the elastic restoring force of the first partition 232, and the adjustment assembly 24 is changed from the critical state to the second engagement state (or from the critical state to the first engagement state), so that the storage device 200 is changed from the stacked state to the unfolded state (or from the unfolded state to the stacked state).

Of course, in a variant embodiment, the storage device 200 may further include an elastic member that provides the elastic driving force, where the elastic member is disposed between the first adjusting mechanism and the second adjusting mechanism, and the elastic member is elastically deformed when the cam structure is not at the lowest point engagement position.

Compared with the prior art, the storage device 200 of the present embodiment can adjust the number/size of storage partitions formed by dividing the accommodating cavity 20 as required; and the first separation frame 232 is convenient to disassemble and assemble, and has good stability in the use process.

The body 31 encloses a generally rectangular parallelepiped containing chamber 30 having an upper opening, and the containing chamber 30 is used for storing various kinds of stored articles such as food, beverage, etc. The body 31 includes a bottom wall, a pair of first side walls 31a disposed opposite to each other, and a pair of second side walls 31b disposed opposite to each other. The bottom wall is for carrying the storage object, and a pair of first side walls 31a and a pair of second side walls 31b respectively extend vertically upward from the bottom wall. Wherein a first side wall 31a simultaneously forms the door of the storage compartment.

In order to clearly express the position and direction described in the present embodiment, the direction defined by the relative positions of the pair of first side walls 31a is defined as the front-rear direction (also referred to as the longitudinal direction), and the direction defined by the relative positions of the pair of second side walls 31b is defined as the left-right direction (also referred to as the lateral direction). That is, the pair of first side walls 31a are disposed to face each other in the front-rear direction, and the pair of second side walls 31b are disposed to face each other in the left-right direction. In addition, a plane defined by the front-rear direction and the left-right direction together is defined as a horizontal plane, and a direction perpendicular to the horizontal plane is defined as a vertical direction.

A pair of guide mechanisms 32 are provided on the pair of second side walls 31b, respectively, that is, one guide mechanism 32 is provided on each second side wall 31 b. The guide mechanism 32 includes a guide bar 32a, a guide member 32b, and a fixing base 32c, wherein: the guide mechanism 32 is fixed on the body 31 through a fixing seat 32c, and the fixing mode between the fixing seat 32c and the body 31 can adopt threaded connection, riveting, buckle connection and the like; the guide bar 32a is parallel to the second side wall 31b and extends in the front-rear direction; the guide member 32b is sleeved on the guide rod 32a and can slide back and forth along the guide rod 32 a. In the present embodiment, the guide bar 32a is provided in a rectangular shape having a square cross section, and the guide piece 32b is adapted to the guide bar 32a such that the guide piece 32b can slide back and forth only along the guide bar 32 a.

The first partition frame 332 is accommodated in the accommodating chamber 30, and may be used to divide the accommodating chamber 30 back and forth. Specifically, the first partition frame 332 includes a partition member transversely disposed (i.e., disposed along a left-right direction) in the accommodating cavity 30 for dividing the accommodating cavity 30, and a vertical plane on which the partition member is disposed defines a partition surface of the first partition frame 332, and the accommodating cavity 30 is divided front and rear by the partition surface of the first partition frame 332. In this embodiment, the partition includes partition rails 332a, 332b provided in a long rod shape, and the partition rails 332a, 332b extend left and right and are spaced apart in the vertical direction.

The first spacer 332 further includes a pair of connectors 332c, the connectors 332c connecting the ends of the spacer bars 332a and the ends of the spacer bars 332b and enclosing a rectangular frame with the spacer bars 332a, 332 b.

The first partition frame 332 is slidably connected to the body 31 along the front-rear direction by the guide mechanism 32, and the size and/or number of the storage partitions formed by dividing the accommodating cavity 30 front-rear can be adjusted by sliding the first partition frame 332 so as to adapt to diversified requirements of different storage articles.

Specifically, the first partition frame 332 includes a pair of fixing portions 332d formed at both left and right ends of the first partition frame 332, each fixing portion 332d being connected to a corresponding guide 32 b. When the guide 32b slides back and forth along the guide bar 32a, the first partition frame 332 slides back and forth in the accommodating chamber 30 synchronously to change the size and/or number of storage partitions at both front and rear sides of the first partition frame 332.

The extending direction of the fixing portion 332d is parallel to the extending direction of the dividing crossbars 332a, 332b, that is, the fixing portion 332d extends in the left-right direction; the fixing portion 332d and the guide 32b are respectively provided with screw holes corresponding to each other, and can be fixedly connected by screw threads.

In the present embodiment, each of the second side walls 31b includes a guide groove 31c extending forward and backward and a hollow assembly chamber, the guide groove 31c communicating the assembly chamber and the accommodation chamber 30. A guide mechanism 32 is disposed within the assembly cavity to increase aesthetics. The left and right ends of the first partition frame 332 pass through the guide groove 31c and are coupled to the guide mechanism 32, and specifically, the fixing portion 332d passes through the guide groove 31c from the accommodating chamber 30 and is coupled to the guide member 32 b.

The second division frame 331 is accommodated in the accommodating chamber 30, and may be used to divide the accommodating chamber 30 left and right. In the present embodiment, the second partition frame 331 is rotatably connected to the first partition frame 332 through the adjusting assembly 34 about the vertical axis t2, and the storage device 300 has a stacked state (refer to fig. 10 b) and an unfolded state (refer to fig. 10 a) according to the positional relationship between the second partition frame 331 and the first partition frame 332. By providing the second partition frame 331 rotatably coupled to the first partition frame 332, the number of storage partitions formed by dividing the accommodating chamber 30 can be adjusted, increasing flexibility in dividing the accommodating chamber 30.

The second partition frame 331 includes a partition body for dividing the accommodating chamber 30, and a vertical plane in which the partition body is located defines a partition surface of the second partition frame 331. The lateral width of the receiving chamber 30 (i.e., the interval between the pair of second side walls 31 b) is greater than the longitudinal width of the receiving chamber 30 (i.e., the interval between the pair of first side walls 31 a), and accordingly, the width of the partition surface of the first partition frame 332 is greater than the width of the partition surface of the second partition frame 331, i.e., the length of the partition is greater than the length of the partition body.

In this embodiment, the separator includes separating longitudinal bars 331a, 331b provided in a long bar shape, and the separating longitudinal bars 331a, 331b are parallel to each other and spaced apart from each other in a vertical direction.

Referring to fig. 10b, when the storage device 300 is in the stacked state, the separation surface of the second separation frame 331 is coplanar with the separation surface of the first separation frame 332, and the separation longitudinal bars 331a, 331b and the separation cross bars 332a, 332b extend in the left-right direction and are located in the same vertical plane, so that the occupied space of the second separation frame 331 can be reduced while at rest, and the cleanliness and the aesthetic appearance can be increased; referring to fig. 10a, when the storage device 300 is in the unfolded state, the second partition frame 331 is disposed crosswise to the first partition frame 332, the accommodating cavity 30 may be divided front and back with the partition surface of the first partition frame 332 as a boundary, and the accommodating cavity 30 may be divided left and right with the partition surface of the second partition frame 331 as a boundary, where the partition surface of the second partition frame 331 and the partition surface of the first partition frame 332 have a non-zero included angle, in this embodiment, the partition surface of the second partition frame 331 is perpendicular to the partition surface of the first partition frame 332, specifically, the partition longitudinal bars 331a and 331b extend in the front-rear direction, the partition cross bars 332a and 332b extend in the left-right direction, and the partition longitudinal bars 331a and 331b are perpendicular to the partition cross bars 332a and 332b.

Further, the divider may also include a glass divider (not shown) that is selectively assembled by a user between divider rail 332a and divider rail 332 b. By providing the partition plates, the stored articles in the storage areas on the front and rear sides of the first partition frame 332 are not contacted, so that odor tainting is avoided, and the stored articles are prevented from sliding off from the space between the partition cross bars 332a and 332 b. Of course, the divider may not only be located between the divider beam 332a and the divider beam 332b, but may also extend partially upward above the divider beam 332a and/or partially downward below the divider beam 332 b.

Further, in the vertical direction, the partition vertical bars 331a and 331b are disposed adjacently, and the partition vertical bar 331a is always higher than the upper boundary of the partition (i.e., the partition cross bar 332a in the present embodiment), and the partition vertical bar 331b is always lower than the lower boundary of the partition (i.e., the partition cross bar 332b in the present embodiment). The dividing vertical bars 331a, the dividing cross bars 332a, the partition plates, the dividing cross bars 332b, and the dividing vertical bars 331b are arranged in this order in the vertical direction. In this way, the second separator 331 does not interfere with the partition when the storage device 300 is in the stacked state.

The second partition frame 331 further includes a pair of connection bars 331c connecting the end portions of the partition longitudinal bars 331a and the end portions of the partition longitudinal bars 331b, the connection bars 331c being disposed non-coplanar with the partition longitudinal bars 331a, 331b, the pair of connection bars 331c being abutted against the partition cross bars 332a, 332b and being located on the front and rear sides of the first partition frame 332, respectively, when the storage device 300 is in the stacked state.

Further, the second partition frame 331 is slidably connected to the first partition frame 332 through the adjusting component 34, that is, the second partition frame 331 is both slidable and rotatable about the vertical axis t2 relative to the first partition frame 332, so that, on one hand, the number of storage partitions formed by dividing the accommodating cavity 30 can be adjusted, and on the other hand, the size of the storage partitions can be adjusted, so that the flexibility of dividing the accommodating cavity 30 is increased.

The second partition frame 331 is slidably connected to the first partition frame 332 through the adjusting component 34, which has various implementation manners: first, the first partition frame 332 is non-slidably connected to the adjustment assembly 34, and the second partition frame 331 is slidably connected to the adjustment assembly 34, so that the size/number of storage partitions formed by dividing the accommodating chamber 30 back and forth by the first partition frame 332 can be adjusted; second, the first partition frame 332 is slidably connected to the adjustment assembly 34, and the second partition frame 331 is non-slidably connected to the adjustment assembly 34, so that the size/number of storage partitions formed by dividing the accommodating chamber 30 left and right by the second partition frame 331 can be adjusted; third, as in the present embodiment, the first partition frame 332 is slidably connected to the adjusting assembly 34, and the second partition frame 331 is also slidably connected to the adjusting assembly 34, so that the size/number of the storage partitions formed by dividing the housing chamber 30 back and forth by the first partition frame 332 and the storage partitions formed by dividing the second partition frame 331 left and right can be adjusted, and the flexibility is improved.

In this embodiment, the adjustment assembly 34 is provided in two, one of which is coupled to the divider rail 331a, the divider rail 332a, and the other of which is coupled to the divider rail 331b, the divider rail 332 b. Referring now to fig. 11-14 b in particular, the construction of the adjustment assembly 34 will be described with reference to the mating of the divider rail 331a and the divider rail 332 a.

The first channel 342 is provided for slidably passing the divider beam 332a such that the first adjustment mechanism 34b slidably mates with the divider beam 332a side-to-side (i.e., the first adjustment mechanism 34b is slidably movable side-to-side along the divider beam 332 a) to slidably couple the adjustment assembly 34 to the first divider 332 side-to-side.

The second adjustment mechanism 34a includes an end cap member 410, a sleeve member 420, and a second channel 341 formed between the end cap member 410 and the sleeve member 420. Wherein, the end cap member 410 includes a hook 411 and a groove 412, and the sleeve member 420 includes a slot 421 and a groove 422 matched with the hook 411; the end cover member 410 and the sleeve member 420 may be coupled in the vertical direction and fastened by the catch 411 and the catch groove 421; groove 412 and groove 422 enclose a second channel 341. The second channel 341 is provided for passing the partition rail 331a therethrough such that the second adjustment mechanism 34a is slidably coupled to the partition rail 331a (i.e., the second adjustment mechanism 34a is slidable along the partition rail 331 a) such that the adjustment assembly 34 is slidably coupled to the second partition frame 331.

Preferably, the sleeve member 420 further includes a guiding slope 4210 for guiding the hook 411 to be smoothly coupled to the slot 421.

Further, the first adjustment mechanism 34b is rotationally coupled to the second adjustment mechanism 34a by a rotation shaft member 430. Specifically, the rotating shaft member 430 includes a member body 432, where the member body 432 includes a hooking portion 4321 and a mating portion 4322, and the hooking portion 4321 and the mating portion 4322 are arranged in a stepped manner and are respectively cylindrical; correspondingly, the sleeve member 420 has a mounting channel 424 matching the shaft member 430, the diameter of the hooking portion 4321 being greater than the diameter of the mounting channel 424, the diameter of the mating portion 4322 being equal to or slightly less than the diameter of the mounting channel 424; when assembled, the shaft member 430 can be vertically and downwardly coupled with the sleeve member 420 from a side above the sleeve member 420 (i.e., a side close to the end cap member 410), the engaging portion 4322 is disposed in the mounting channel 424 in a penetrating manner, and the hanging portion 4321 is limited by the sleeve member 420, so that the shaft member 430 is vertically and downwardly inseparably assembled to the sleeve member 420.

The shaft member 430 includes a mating surface 4320 formed on an outer surface of the mating portion 4322, and the sleeve member 420 includes a mating surface 4240 formed on an inner wall of the mounting channel 424, the mating surface 4240 and the mating surface 4320 being adapted to rotationally mate the shaft member 430 within the mounting channel 424. In the present embodiment, the rotation shaft member 430 has a central axis defining a vertical axis t2.

One end of the engaging portion 4322 of the rotation shaft member 430 is provided with an installation hole, which is engaged with the screw 460 to fixedly connect the rotation shaft member 430 to the fixing member 440.

Further, when the first adjusting mechanism 34b and the second adjusting mechanism 34a rotate relatively, the separating rail 332a and the separating vertical rod 331a rotate relatively under the driving of the first adjusting mechanism 34b and the second adjusting mechanism 34a, respectively, and the first separating frame 332 and the second separating frame 331 rotate relatively. In the present embodiment, with the body 31 as a reference, the second regulating mechanism 34a rotates about the vertical axis t2 while the first regulating mechanism 34b does not rotate.

Further, the sleeve member 420 further includes at least two locating grooves 423 recessed on the mating face 4240 (i.e., the inner wall of the mounting channel 424). The fitting portion 4322 of the member body 432 is provided with a horizontally extending fitting hole; the rotating shaft member 430 further includes a resilient telescopic member 431 connected to the member body 432, wherein the resilient telescopic member 431 is disposed in the mating hole and at least a portion of the resilient telescopic member 431 protrudes out of the mating surface 4320 (i.e., the outer surface of the mating portion 4322) in a free state.

When the first adjustment mechanism 34b and the second adjustment mechanism 34a are rotated relative to each other about the vertical axis t 2: at the position between two adjacent positioning grooves 423, under the supporting action of the matching surface 4240, the elastic telescopic part 431 is compressed and deformed and contracts inwards the matching hole; at the position of the positioning groove 423, under the action of self elastic restoring force, the elastic telescopic part 431 at least partially protrudes out of the matched surface 4320 and is clamped in the positioning groove 423, so as to realize the rotation positioning of the first adjusting mechanism 34b and the second adjusting mechanism 34 a.

Specifically, the elastic telescopic member 431 includes an elastic portion 4311 penetrating the fitting hole and a ball 4312 rolling on an end of the elastic portion 4311. When the first adjustment mechanism 34b and the second adjustment mechanism 34a are rotated relative to each other about the vertical axis t 2: at a position between two adjacent positioning grooves 423, under the abutting action of the mating surface 4240, the elastic part 4311 is compressed and deformed, and the balls 4312 shrink inwards of the mating holes and roll along the mating surface 4240; at the position of the positioning groove 423, under the self elastic restoring force of the elastic part 4311, the ball 4312 protrudes outwards to the matched surface 4320 and is clamped in the positioning groove 423, so as to realize the rotation positioning of the first adjusting mechanism 34b and the second adjusting mechanism 34 a.

In the present embodiment, the positioning slots 423 are configured to be 4 and equally divide the circumference, so that when the first adjusting mechanism 34b and the second adjusting mechanism 34a rotate around the vertical axis t2, the balls 4312 move from one positioning slot 423 to the adjacent other positioning slot 423, so that the storage device 300 is correspondingly switched between the stacked state and the unfolded state.

Specifically, when the second partition frame 331 rotates about the vertical axis t2 relative to the first partition frame 332, a process of changing the storage device 300 from the stacked state to the unfolded state (a process of changing the storage device 300 from the unfolded state to the stacked state is opposite to the process, and is not repeated) is taken as an example:

Referring to fig. 14a, when the storage device 300 is in the stacked state, the first channel 342 and the second channel 341 are parallel and extend in the left-right direction (x direction in the drawing), and accordingly, the partition rail 332a and the partition vertical rod 331a extend in the left-right direction (x direction in the drawing), the partition surface of the first partition frame 332 and the partition surface of the second partition frame 331 are parallel, and at this time, the balls 4312 protrude outwards and fit into the positioning grooves 423;

When the storage device 300 is switched from the stacked state to the unfolded state, the second adjusting mechanism 34a drives the separation vertical rod 331a to rotate around the vertical axis t2 (taking the body 31 as a reference), and the second separation frame 331 rotates around the vertical axis t2 relative to the first separation frame 332; under the abutting action of the mating surface 4240, the elastic portion 4311 is compressed and deformed, the balls 4312 shrink into the mating hole and disengage from the positioning grooves 423 where they were located, and then the balls 4312 roll along the mating surface 4240;

Referring to fig. 14b, when the storage device 300 is in the unfolded state, the first channel 342 is perpendicular to the second channel 341, the first channel 342 and the partition rail 332a still extend along the left-right direction (x direction in the drawing), the second channel 341 and the partition vertical rod 331a extend along the front-back direction (y direction in the drawing), the partition surface of the first partition frame 332 is perpendicular to the partition surface of the second partition frame 331, and at this time, the balls 4312 outwards extend and are clamped in the other positioning groove 423 under the self elastic restoring force of the elastic portion 4311.

Further, in the present embodiment, the mating hole extends horizontally and penetrates the member body 432; the balls 4312 are provided in two and are provided at both ends of the elastic portion 4311 in a rolling manner. When the first adjustment mechanism 34b and the second adjustment mechanism 34a are rotated relative to each other about the vertical axis t 2: under the supporting action of the mating surface 4240, the elastic part 4311 is compressed and deformed, and the two balls 4312 shrink inwards of the mating hole and synchronously roll along the mating surface 4240; at the position of the positioning groove 423, under the self elastic restoring force of the elastic part 4311, the two balls 4312 are protruded outwards from the matched surface 4320 and are synchronously clamped in the corresponding positioning groove 423, so that the rotation resistance is further reduced.

Compared with the prior art, the embodiment has the following beneficial effects: by arranging the movable fit of the first partition frame 332 and the second partition frame 331, the degree of freedom and flexibility of the division of the accommodating cavity 30 are improved so as to adapt to different storage requirements; the adjusting component 34 has a smart structure, can be assembled quickly, and can also be disassembled/replaced in time to further enhance the flexibility of the division; by selectively adding the glass partition plates, the cross sliding of the objects among different storage partitions can be avoided.

Although the present disclosure describes embodiments, not every embodiment contains only one independent technical solution, and those skilled in the art should understand that the disclosure may also combine technical solutions in each embodiment as a whole to form other embodiments that can be understood by those skilled in the art.
