In other words, on the basis that the first mating structure 20, the second mating structure 50, the third mating structure 30 and the fourth mating structure 60 are mated with each other, other mating structures can be added to further assist in limiting according to the requirement, so that it is ensured that relative displacement is not easy to occur between the first stacking member 10 and the second stacking member 40 after stacking and fixing.

In one embodiment of the present utility model, the stacking system 100 has a locked state in which the first stack 10 and the second stack 40 can be connected and locked to each other such that no relative displacement between the second stack and the first stack can occur.

Further, in one embodiment of the present utility model, the first stack 10 and the second stack 40 can be locked in three directions X, Y, Z by the pressure on the former. Namely, the two can automatically form a locking state by the pressure generated when the two are stacked; in this locked state, the second stack 40 is not movable in the horizontal direction and the vertical direction with respect to the first stack 10, wherein the horizontal direction includes at least the X-direction and the Y-direction, and the vertical direction includes at least the Z-direction.

It is emphasized that the "pressure" in "the first stack 10 and the second stack 40 can be locked in three directions X, Y, Z by the pressure of the former may include the pressure generated by the self-weight of the former, and may also include the pressure generated by the self-weight of the former and the pressure externally applied to the former. Alternatively, in this embodiment, the pressure refers to the gravitational force generated when the second stack 40 is placed.

Referring to fig. 1 to 8, illustratively, in a first embodiment provided by the present utility model, a second stack 40 may be directly stacked on the first stack 10; alternatively, the first stacking member 10 and the second stacking member 40 are both storage boxes, and alternatively, the storage boxes are rectangular solids, and the two storage boxes are the same in size.

It will be appreciated that in other embodiments, the second stack 40 may be one or more, with the length and/or width of a single second stack 40 being less than the length and/or width of the first stack 10; when the plurality of second stacked pieces 40 are provided, the total length and the total width of the plurality of second stacked pieces 40 after being spliced in parallel are not greater than those of the first stacked piece 10.

It is understood that when the storage case is in the shape of a polygonal column or a cylinder, the X direction, the Y direction, and the Z direction may be determined according to circumstances.

It will be appreciated that in the same stacking system 100, in the case of determining the X-direction, Y-direction, and Z-direction coordinate system, the correspondence between the length direction, width direction, and height direction of different stacks and the X-direction, Y-direction, and Z-direction are related to the length, width, height, and placement direction of the stacks, and need to be corresponding according to the specific situation. For example, in the same X, Y, Z direction coordinate system, the length direction, the width direction, and the height direction of the first stack 10 may correspond to the X direction, the Y direction, and the Z direction, respectively, while the length direction, the width direction, and the height direction of the second stack 40 may correspond to the Y direction, the X direction, and the Z direction, respectively.

Referring to fig. 1 to 8 again and fig. 9 to 25 together, the first stacking member 10 is taken as an example, the second stacking member 40 is taken as an example, in the first embodiment provided by the present utility model, the first matching structure 20 includes a first elastic member 21 and a first movable member 22, the first elastic member 21 can elastically act on the first movable member 22, and when the second stacking member 40 is stacked on the first stacking member 10, the first movable member 22 can move on the first stacking member 10 under the pressure of the second stacking member 40; when the second stacking member 40 is stacked in place, the first movable member 22 can make the first movable member 22 and the second matching structure 50 mutually clamped under the elastic action of the first elastic member 21, so that the locking state is realized by the pressure of the second stacking member 40.

In other words, in the present embodiment, the stacking system 100 can implement gravity self-locking by the weight of the former, so that the first stacking member 10 and the second stacking member 40 can be stably stacked and locked without additional force, and the risk of separating the two members from each other during transportation is effectively reduced or avoided.

Of course, it is understood that in other embodiments, additional pressure may be applied to the second stack 40 on the basis of gravity of the second stack 40 to form a locked state, which is not described herein.

It will be appreciated that in other embodiments, the up-down position of the first stack 10 and the second stack 40 may be set as desired. In other words, in other embodiments, the first stack 10 may also be stacked above the second stack 40.

Referring to fig. 8-20, further, in a first embodiment of the present utility model, the first movable member 22 is slidably coupled to the first stack 10. It can be appreciated that the sliding connection is simple and relatively stable.

In other words, in the present embodiment, the first movable member 22 is capable of sliding in the X direction or the Y direction of the first stack 10 to the outside of the first stack 10. It is emphasized that in the present embodiment, the X direction refers to the length direction of the first stack 10, the Y direction refers to the width direction of the first stack 10, and the Z direction refers to the height direction of the first stack 10.

Referring again to fig. 1-20, and also to fig. 21-26, optionally, in the present embodiment, the first movable member 22 is capable of moving along the X direction (length direction) of the first stack 10; the first movable member 22 includes a base 221 and a first clamping portion 222 disposed on the base 221, the base 221 is slidably connected to the first stacking member 10, the second mating structure 50 includes a second clamping portion 51 disposed on the second stacking member 40, and in a locked state, the first clamping portion 222 can be clamped with the second clamping portion 51 under the action of the first elastic member 21, so as to at least limit the second stacking member from being separated from the first stacking member along the Z direction.

It will be appreciated that the specific configuration of the first and second catch portions 222, 51 may be modified as desired to simultaneously limit movement of the second stack relative to the first stack 10 in the X-direction and/or the Y-direction. Correspondingly, the third mating structure 30 and the fourth mating structure 60 may additionally restrict the movement of the second stack 40 in other directions, so as to ensure that the first stack 10 and the second stack 40 cannot relatively displace in the three directions X, Y, Z in the locked state.

It should be noted that, alternatively, in the present embodiment, the first clamping portion 222 is protruding on the base 221, and the second clamping portion 51 is protruding on the bottom of the second stacking member 40. It will be appreciated that the protrusions are opposed and do not represent the entire surface of the protruding base 221 or the bottom of the second stack 40. The meaning of the protruding arrangement will not be described in detail below, as long as the required functions can be realized.

Referring to fig. 4 and 6 again, in the present embodiment, the second clamping portion 51 may protrude from the bottom of the second stacking member 40, or may not protrude from the bottom of the second stacking member 40, so long as the overall structure of the bottom of the second stacking member 40 is capable of automatically locking the second stacking member 40 to the first stacking member 10 without affecting the stacking of the second stacking member to the first stacking member 10. For example, in the present embodiment, the bottom of the second stacking member 40 may be provided with a concave area (not numbered), and the second clamping portion 51 protrudes from the concave area, but does not protrude from other portions of the bottom of the second stacking member 40.

Referring to fig. 1, 2, 4 and 5 again, it will be understood that, to facilitate the snap fit between the first card portion 222 and the second card portion 51, one of the first card portion 222 and the second card portion 51 may have pins, the other one may have a slot 511, and the slot 511 may have one slot or a plurality of slots to selectively define the moving direction of the second stacking member 40 according to the requirement. In other words, the differently shaped slots 511 in cooperation with the pins may correspondingly limit movement of the second stack 40 in one or more directions.

Illustratively, in the present embodiment, the first card portion 222 has pins (not numbered), and the second card portion 51 is provided with a slot 511; in the locked state, the pins of the first card portion 222 can be inserted into the slots 511 by the first elastic member 21. Referring to fig. 5 again, further, in the present embodiment, the slot 511 is a concave slot, that is, the slot 511 has only one notch, so that the side walls around the slot 511 can all play a limiting role, wherein the upper and lower side walls of the slot 511 can define the second stacking member 40 to move along the Z direction, and the left and right side walls of the slot 511 can define the second stacking member 40 to move along the Y direction; the side wall of the slot 511 opposite the slot can restrict the second stack 40 from moving in the X direction to a side away from the slot.

It will be appreciated that in other embodiments, the slot 511 may have only upper and lower sidewalls, so that movement of the second stack 40 in the Z direction is selectively restricted, and correspondingly movement of the second stack in the X and Y directions may be restricted by the engagement of the third and fourth engagement structures 30 and 60.

Referring to fig. 1, 4 and 6 to 14 again, in the present embodiment, a movable slot 11 is formed at the top of the first stacking member 10, the movable slot 11 is used for installing a first movable member 22, the movable slot 11 has a first slot 111 and a second slot 112 that are mutually communicated, the first slot 111 is formed at a side wall of the first stacking member 10, the second slot 112 is formed at a top wall of the first stacking member 10, and the first movable member 22 can move towards the direction of the first slot 111.

It will be appreciated that in the present embodiment, the direction in which the first elastic member 21 is disposed faces the first side wall 113, in other words, the direction in which the first elastic member 21 is disposed is parallel to the length direction of the first stack 10.

Further, referring to fig. 1 to 8, in the present embodiment, the third mating structure 30 is identical to and disposed opposite to the first mating structure 20, and the fourth mating structure 60 is identical to and disposed opposite to the second mating structure 50. This arrangement facilitates quick stacking and locking of the first and second stacks 10, 40 and ensures that the first and third mating structures 20, 30 are capable of mating with the second and fourth mating structures 50, 60, respectively, to limit relative displacement between the second and first stacks 40, 10 in at least the Z-and Y-directions.

Further, in one embodiment of the present utility model, a side of the second clamping portion 51 opposite to the slot opening of the slot 511 can abut against the first side wall 113. So set up, the second card portion 51 of the second mating structure 50 and the second card portion 51 of the fourth mating structure 60 can cooperate with each other to ensure that the movement of the second stacking member 40 along the X direction is limited, and in the locked state, after the first card portion 222 and the second card portion 51 are clamped with each other, the first stacking member 10 and the second stacking member 40 can be stably stacked, and cannot be separated relatively in the X direction, the Y direction and the Z direction.

It will be appreciated that, in other embodiments, a side of the second card portion 51 opposite from the slot 511 may not abut the first side wall 113, and movement of the second stack 40 in the X direction may be relatively limited in other manners; for example, an additional abutment protrusion is provided at the bottom of the second stack 40 corresponding to the first mating structure 20 and the third mating structure 30, wherein the abutment protrusion corresponding to the first mating structure 20 can abut against the first sidewall 113 of the movable slot 11 at the first mating structure 20, and in the locked state, the abutment protrusion can limit the movement of the second stack 40 in the direction approaching the third mating structure 30 in the X direction; further, in the locked state, an abutment projection corresponding to the third fitting structure 30 can abut against the first side wall 113 of the movable groove 11 at the third fitting structure 30, the abutment projection being capable of restricting the movement of the second stack 40 in the X direction in a direction approaching the first fitting structure 20; in this way, without depending on the second card portion 51, it is still possible to ensure that the movement of the first stack 10 and the second stack 40 in the X direction is effectively restricted.

It will be appreciated that the location of the abutment protrusion may be flexibly changed, and may be provided separately or integrally with other structures, as long as the abutment protrusion is capable of restricting the movement of the second stack 40 in the X direction in cooperation with the side wall of the movable slot 11.

In other words, in the present embodiment, the movement of the second stacked member 40 in the X direction can also be restricted depending on the engagement between the fifth engaging structure 12 and the sixth engaging structure 41, without being restricted depending on the engagement of the second engaging portions 51 on both sides or the additional abutment projections, so that the setting position of the second engaging portions 51 can be made more free and flexible.

Referring again to fig. 1-8, optionally, in this embodiment, the fifth mating structure 12 and the sixth mating structure 41 are capable of mating with each other to limit movement of the second stack in the X-direction and the Y-direction.

Thus, the restriction of the movement of the second stack 40 in the Y direction can be reinforced while restricting the movement of the second stack 40 in the X direction. And the first stacking piece 10 and the second stacking piece 40 can be ensured to be more compact when being stacked, and can be respectively and stably placed independently after being separated.

Optionally, in this embodiment, the groove is non-circular, and peripheral walls capable of playing a limiting role are provided around the groove; it will be appreciated that the latch and the recess may be in one-to-one correspondence, or one recess may cooperate with a plurality of latches, so long as the movement of the second stacking member 40 can be limited in the X-direction or the X-direction and the Y-direction. Further, in other embodiments, the shape of the groove may be circular, arcuate, or other shapes.

It will be appreciated that in other embodiments, the fifth mating structure 12 and the sixth mating structure 41 may be embodied as other structures as long as the relative displacement between the first stack 10 and the second stack 40 can be assisted in limiting.

It should be noted that, in other embodiments, when the two positioning engaging portions 70 at the bottom of the second stacking member 40 are bumps disposed at the bottom of the second stacking member 40, the two positioning engaging portions 70 may also be used as abutting protrusions, that is, the two positioning engaging portions 70 may not only play a role in positioning, but also play a role in restricting the movement of the second stacking member 40 along the X direction. It should be emphasized that in this embodiment, the side of the positioning engaging portion 70 that is relatively close to the center of the second stack 40 needs to be able to abut against the first side wall 113. It will be appreciated that in other embodiments, the abutting blocks may be disposed on the first side wall 113, so that the positioning matching portion 70 can abut against the abutting blocks on the first side wall 113 to limit, so long as the second stacking member 40 cannot be displaced relative to the first stacking member 10 in the X direction.

Referring to fig. 26 again, alternatively, in this embodiment, a side of the positioning member 81 abutting against the positioning matching portion 70 is an arc-shaped abutting surface 812. So configured, the positioning member 81 is facilitated to rotate within the first fitting groove 2211 while the abutting positioning action is ensured. It will be appreciated that, correspondingly, in the unlocked state, the side where the positioning engaging portion 70 and the positioning member 81 abut against each other may also be an arc-shaped abutting surface. To further facilitate the abutting positioning of the two and at the same time facilitate the rotation of the positioning member 81 within the first fitting groove 2211.

By this arrangement, the stability of the positioning member 81 can be maintained, and the positioning member 81 is prevented from being separated from the first fitting groove 2211.

Referring again to fig. 26, alternatively, in this embodiment, the second elastic member 82 is a torsion spring. The tower spring is small in size, large in load and strong in variable stiffness, can be suitable for small space, bears larger pressure, and is good in damping rebound effect. It is understood that in other embodiments, the second resilient member 82 includes, but is not limited to, a tower spring, a compression spring, a torsion spring, a dome, and the like.

It will be appreciated that the top of the first stack 10 may be provided with sets of mating assemblies, each set of mating assemblies may include one or more first mating structures 20 and one or more third mating structures 30, each set of mating assemblies locating one second stack 40. In other words, the first stacking member 10 can position one second stacking member 40 by combining one or more first matching structures 20 and one or more third matching structures 30, and the number and arrangement positions of the first matching structures 20 and the third matching structures 30 required for positioning one second stacking member 40 can be selected according to the requirements, so that the top of the first stacking member 10 can fix different sizes and/or different numbers of second stacking members 40.

It is further understood that the number and placement of the second and fourth mating structures 50, 60 on the second stack 40 do not necessarily correspond exactly to the number and placement of the first and third mating structures 20, 30 on the first stack 10, but need only correspond to the first and third mating structures 20, 30 for securing the second stack 40.

Thus, in actual engagement, after the position of the first engagement structure 20 on the first stack 10 for fixing the second stack 40 is determined, another position or positions on the first stack 10 that are locked with each other with the second stack 40 can be the third engagement structure 30.

It will be appreciated that the top of the first stack 10 and/or the second stack 40 can be configured to hold the second stacks 40 of different sizes by flexibly providing the first mating structure 20 and the third mating structure 30.

In this way, the upper and lower sides of each stack can be locked to each other stack.

It will be appreciated that the designations of the first stack 10 and the second stack 40 described above are relative; for example, when three stacks are stacked in the height direction, the middle stack is the second stack 40 with respect to the stack located therebelow and the first stack 10 with respect to the stack located thereabove. In other words, the stacking system 100 may be formed with a plurality of stacks stacked in sequence.

It is further understood that, in other embodiments, when a plurality of third mating structures 30 are provided on the first stack 10, a portion of the third mating structures 30 may have the same structure as the first mating structures 20, and a portion of the third mating structures 30 may have a structure different from the first mating structures 20; the determination of the position of the third mating structure 30 is related to the size of the second stack 40 stacked onto the first stack 10.,

Specifically, when the size of the second stacking member 40 is the same as the size of the first stacking member 10, the limiting structure having the same structure as the first matching structure 20 can be the third matching structure 30. When the size of the second stacking member 40 is smaller than that of the first stacking member 10, the limiting structure with the same structure as the first matching structure 20 may be another first matching structure 20, and the two first matching structures 20 respectively match with a set of clamping plates to lock one second stacking member 40, and at this time, the corresponding clamping plate structure is the third matching structure 30. In the present embodiment, each first mating structure 20 cooperates with two card structures to lock one second stack 40, i.e. one first mating structure 20 cooperates with two third mating structures 30 implemented as cards to lock one second stack 40. In this way, the first and second stacks 10 and 40 can be flexibly stacked with stacks of different specifications according to circumstances.

Referring again to fig. 6, it is to be appreciated that the first stack 10 and the second stack 40 include, but are not limited to, storage bins, carts, and the like.
