As shown in fig. 1 to 7, the push-pull shelf assembly according to the embodiment of the first aspect of the present invention includes a slide rail 128, a slide base 102, and a shelf 100; the sliding seat 102 is slidably mounted to the sliding rail 128; the shelf 100 is mounted to the slide 102 and is switchable between a pulled-out position, in which the shelf 100 is horizontally rotatable with respect to the slide 102, and a pushed-back position.

According to the push-pull shelf assembly provided by the embodiment of the invention, the sliding seat 102 is arranged on the sliding rail 128, the shelf 100 is arranged on the sliding seat 102, when the shelf 100 is pulled out, the shelf 100 can rotate in a horizontal plane relative to the sliding seat 102, so that a user can rotate the shelf 100 after pulling out the shelf 100, and further, articles can be conveniently taken from the shelf 100 or placed in the shelf 100, and great convenience is brought to the user.

The push-pull shelf assembly provided by the embodiment of the invention is applied to a refrigerator as an example to be described below.

The shelf 100 in the embodiment of the present invention is used for holding articles, wherein the shelf 100 may be single or multiple. When the shelf 100 is plural, the shelves 100 may be arranged in sequence along the height direction of the door body. Also, the spacing between two adjacent shelves 100 may be provided in an equal or unequal manner.

The sliding seat 102 is slidably mounted on the sliding rail 128 and is used for driving the shelf 100 to move along a direction perpendicular to the door body. That is, when the user pulls the door body outward, the sliding seat 102 drives the shelf 100 to move to the left in fig. 1, and at this time, the shelf 100 is in the pulled-out position; when the user pushes the door inward, the sliding seat 102 drives the shelf 100 to move to the right in fig. 1, and the shelf 100 is at the push-back position.

When the shelf 100 is pulled out, the shelf 100 can rotate in a horizontal plane with respect to the sliding seat 102. That is, the shelf 100 may be rotated flat in a horizontal plane relative to the slide block 102 along the direction of the vertical axis. In this way, after the user pulls out the shelf 100, the user can adjust the shelf 100 to a proper angle by rotating the shelf 100, and then take items out of the shelf 100 or put items into the shelf 100. Therefore, the user does not need to twist the body or use a non-dominant hand to operate, the original side operation mode of the user is changed into the front operation mode, and great convenience is brought to the user.

Referring to fig. 1 and 2 in combination, a shelf 100 in an embodiment of the present invention is mounted to a slide 102 by a pivot assembly that includes a pivot support plate 104 and a center post 106.

Wherein, the rotation support plate 104 is installed at the bottom of the shelf 100; the central column 106 is disposed on the sliding seat 102; a rotation support plate 104 is inserted on the center post 106 so that the shelf 100 can rotate relative to the sliding seat 102.

A rotation support plate 104 may be mounted to the bottom of the shelf 100 by means of screws or the like, and the rotation support plate 104 serves to center the shelf 100, to define the relative distance between the shelf 100 and the sliding seat 102, and to support the overall weight of the shelf 100. Thus, the rotation support disk 104 may be made of a lightweight, high strength material, such as an aluminum alloy.

The central column 106 may be connected to the center of the sliding seat 102 by welding, screwing, or the like, or may be integrally formed with the sliding seat 102 and disposed at the center of the sliding seat 102. The center post 106 in this embodiment may be provided as a cylindrical structure that protrudes upward from the shoe 102. Correspondingly, a circular groove structure corresponding to the central column 106 is arranged at the bottom of the rotation support plate 104 and the shelf 100 at a position corresponding to the central column 106. It should be noted that, because the two plates are sequentially inserted, the bottom of the circular groove on the rotation support plate 104 protrudes from the upper surface of the rotation support plate 104. That is, the central column 106 is inserted into the circular groove of the rotation support plate 104, and the protrusion formed at the bottom of the circular groove of the rotation support plate 104 is inserted into the circular groove at the bottom of the shelf 100.

In addition, in order to further ensure the coaxiality of the center post 106 and the protruding structures at the bottoms of the rotation support plate 104 and the shelf 100, a through hole can be respectively formed in the center post 106 and the protruding structures at the bottoms of the rotation support plate 104 and the shelf 100, and then the center post, the rotation support plate 104 and the protruding structures at the bottoms of the shelf 100 are sequentially connected through the through holes by using elements such as rivets. Thus, when the shelf 100 is rotated with respect to the sliding seat 102, the rotation accuracy is higher.

Further, as shown in fig. 3, the bottom of the rotation support plate 104 is provided with a rib 144, and a side of the rib 144 facing the sliding seat 102 is in contact with the upper surface of the sliding seat 102. The convex rib 144 is arc-shaped, and the center of the arc-shaped convex rib 144 is concentric with the center of the center post 106, so that when the rotation support plate 104 rotates, the contact mode between the rotation support plate 104 and the sliding seat 102 is changed from surface contact to line contact, the contact area is reduced, the friction force between the rotation support plate 104 and the sliding seat 102 is further reduced, and the rotation flexibility of the movement support plate is further improved.

Further, in order to ensure that the shelf 100 is more stable when the user rotates the shelf 100, as shown in fig. 1 to 2, a guide post 124 is provided on one of the rotation support plate 104 and the sliding seat 102, and a guide rail 126 engaged with the guide post 124 is provided on the other of the rotation support plate 104 and the sliding seat 102.

The guide post 124 is disposed on the sliding seat 102, and the guide rail 126 is disposed at the bottom of the rotation support plate 104. The guide post 124 may be disposed on the centerline of the slide 102 and the guide rail 126 may be a groove disposed on the bottom of the rotation support plate 104. Wherein the guide post 124 is inserted into the groove. The groove for forming the guide rail 126 may be an arc groove centered on the center of the rotation support plate 104, and the arc degree of the arc groove may be set according to actual requirements, for example, the arc groove may be a semicircular groove. That is, the maximum rotation angle of the shelf 100 to the left and right may be 90 degrees, that is, the shelf 100 may be rotated from the vertical direction to the horizontal direction.

Of course, the guide rail 126 may be a boss disposed along the rotation path of the rotation support plate 104, and correspondingly, the top end of the guide post 124 may be provided with a sliding slot matched with the boss.

In addition, in order to achieve the purpose that the shelf 100 can be positioned after rotating to a certain angle, a plurality of positioning holes may be formed at certain intervals at the bottom of the groove forming the guide rail 126, and when the guide post 124 moves to the position of the positioning hole, the guide post 124 can slide into the positioning hole to position the rotating angle of the shelf 100. When it is necessary to continue rotating the shelf 100 or to restore the shelf 100 to the original state, a certain external force may be applied to the shelf 100 so that the guide posts 124 are disengaged from the positioning holes.

Referring collectively to fig. 1, 2 and 5, the push-pull shelf assembly further includes cooperating locking wheels 108, locking blocks 110, mounting caps 112 and resilient struts 114.

Wherein, the locking wheel 108 is arranged on one of the shelf 100 and the sliding seat 102, and the locking block 110 is arranged on the other of the shelf 100 and the sliding seat 102; the locking wheel 108 and the locking block 110 are engaged with each other to enable the shelf 100 to be switched between an initial state and a rotated state, in the initial state, the locking wheel 108 is engaged with the locking block 110 to lock the relative position between the shelf 100 and the sliding seat 102, and in the rotated state, the locking wheel 108 and the locking block 110 are disengaged from each other to unlock the relative position between the shelf 100 and the sliding seat 102.

The installation cover 112 is disposed on the shelf 100 or the sliding seat 102, an accommodating groove is disposed inside the installation cover 112, the locking wheel 108 is disposed in the accommodating groove, and the width of the opening of the accommodating groove is smaller than the diameter of the locking wheel 108.

The elastic rod 114 is disposed in the receiving groove, and in an initial state, the elastic rod 114 abuts the locking wheel 108 against the locking block 110, and in a rotational state, the elastic rod 114 abuts the locking wheel 108 against the opening of the receiving groove.

Specifically, with continued reference to fig. 1, 2 and 5, the mounting cover 112 is provided with a connecting head, and correspondingly, a connecting hole corresponding to the connecting head is formed at the bottom of the shelf 100. The connector may be in the form of a column structure member disposed at a position on the mounting cover 112 near the four top corners, and a disc structure member having a slightly larger diameter is disposed at the top of each column structure member. The coupling holes may be in the form of four gourd holes provided at the bottom of the shelf 100. When the disc-shaped structural member is inserted into the gourd hole, the mounting cover 112 is slid to clamp the mounting cover 112 to the bottom of the shelf 100, thereby achieving the quick assembly and disassembly of the mounting cover 112.

As shown in fig. 5, a receiving groove capable of receiving the locking wheel 108 is provided inside the mounting cover 112, and a portion of the locking wheel 108 can extend out of the mounting cover 112 and abut against the locking block 110. In addition, in order to prevent the locking wheel 108 from being removed from the mounting cover 112, the width of the opening of the receiving groove is smaller than the diameter of the locking wheel 108. For example, the opening of the receiving groove may be formed in a closed shape, that is, both side edges at the position of the opening are formed in an inwardly contracted shape, so that the lock wheel 108 can be prevented from coming out of the mounting cover 112 through the closed opening.

The resilient strut 114 is provided to provide sufficient resilient support to the locking wheel 108 to enable the locking wheel 108 to be tightened against the locking block 110.

Specifically, with continued reference to fig. 5, a mounting groove 116 is formed on a side wall of the receiving groove, a first end of the elastic strut 114 extends into the mounting groove 116, and a second end of the elastic strut 114 abuts against a side surface of the locking wheel 108. Wherein, the mounting groove 116 runs through the groove side wall of holding tank, namely, when the locking wheel 108 extrudes the elastic supporting rod 114 to the inside of mounting cover 112, the first end of the elastic supporting rod 114 can wear out the mounting groove 116, thus ensuring that the locking wheel 108 and the elastic supporting rod 114 have a larger displacement, and meeting the space requirement when the locking wheel 108 and the elastic supporting rod 114 move.

With continued reference to fig. 5, the elastic support rod 114 of the embodiment of the present invention includes a support rod 118, a support head 120 and a first elastic member 122; a first end of the supporting rod 118 is inserted into the mounting groove 116, a supporting head 120 is arranged at a second end of the supporting rod 118, and the supporting head 120 is provided with a first concave part matched with the locking wheel 108; the first elastic member 122 is sleeved on the supporting rod 118, and two ends of the first elastic member 122 are respectively abutted against the supporting head 120 and the mounting groove 116.

When the locking wheel 108 presses the elastic bar 114 toward the inside of the mounting cover 112, the first end of the support bar 118 (i.e., the right end of the support bar 118 in fig. 5) is inserted into the mounting groove 116 and can reciprocate in the mounting groove 116.

The supporting head 120 connected to the second end of the supporting rod 118 is always attached to the side of the locking wheel 108, and in order to ensure that the supporting head 120 is attached to the locking wheel 108 more tightly, a first recess adapted to the side of the locking wheel 108 is provided on the supporting head 120, and the surface of the first recess may be arc-shaped.

The first elastic member 122 may be a spring, which is sleeved on the supporting rod 118 and has two ends respectively inserted into the mounting groove 116 and tightly pressed against the supporting head 120. In order to achieve the purpose that the spring can always prop against the supporting rod 118 and then the supporting rod 118 drives the supporting head 120 to prop against the locking wheel 108, it is necessary to ensure that one end of the spring inserted into the mounting groove 116 can provide a reverse supporting force for the spring, and therefore, a boss type structure can be arranged in the mounting groove 116 or the notch of the mounting groove 116 can be set to be in a closed shape. Therefore, the reverse supporting force can be provided for the spring, the spring can be prevented from being separated from the mounting groove 116, the locking wheel 108 can be always tightly pushed, and the problem that the locking wheel 108 and the locking block 110 are positioned and failed is solved.

With continued reference to fig. 5, the locking block 110 has a second recess portion engaged with the locking wheel 108, and guide surfaces disposed on two sides of the second recess portion along the rotation direction of the shelf 100. Likewise, the surface of the second recess in the lock block 110 may be arcuate in shape for better abutment of the lock block 110 with the lock wheel 108. In addition, to ensure that the locking wheel 108 slides into the locking block 110 more smoothly, the guide surface may be configured as an inclined surface, and the specific inclined direction is the direction of sliding from the locking wheel 108 into the locking block 110, and the guide surface is gradually inclined upwards. Also, this can effectively prevent the locking wheel 108 from slipping out of the locking block 110 when the shelf 100 is in the initial state. The guide surface may be a flat surface or an arc surface as long as the above-described object can be achieved.

Further, to ensure that the shelf 100 is positively disposed on the sliding seat 102 when the locking wheel 108 is engaged with the locking block 110, in this embodiment, the center point of the mounting cover 112, the center point of the locking block 110, and the center point of the center post 106 are located on the same line, and the line is preferably the center line of the sliding seat 102 along the length direction.

The process of engaging the locking wheel 108 with the locking block 110 will be briefly described as follows:

when the shelf 100 is in the initial state, or the shelf 100 is pulled out but not rotated, the locking wheel 108 can be pressed against the second recess on the locking block 110 under the elastic support of the elastic strut 114. When the shelf 100 needs to be rotated, a certain external force can be applied to the shelf 100 to drive the shelf 100 to rotate, when the external force applied to the shelf 100 is greater than the abutting force between the locking wheel 108 and the locking block 110, the locking wheel 108 is stressed to gradually retract into the mounting cover 112, the locking wheel 108 slides out of the second concave part on the locking block 110 and is separated from the locking block 110, and at the moment, a user can rotate the shelf 100 according to actual use requirements. At this time, the locking wheel 108 and the locking block 110 are separated from each other, so that the user can adjust the rotation angle of the shelf 100 relative to the sliding seat 102.

Conversely, when the user rotates the shelf 100 to the initial position, the locking wheel 108 slides along the edge of the locking block 110 into the second recess on the locking block 110, the locking wheel 108 is forced to gradually taper back into the mounting cover 112 until the locking wheel 108 completely enters the second recess on the locking block 110, and the locking wheel 108 is pressed against the second recess on the locking block 110 under the supporting force of the elastic strut 114, so as to lock the relative positions of the shelf 100 and the sliding seat 102.

Further, after the shelf 100 is pulled out and rotated by a certain angle, in order to avoid that the shelf 100 is pushed back by a human error operation to collide with the refrigerator body, referring to fig. 1, 2 and 4, the push-pull shelf assembly in the embodiment of the present invention further includes a slide rail base 130 and a stopping mechanism.

The slide rail base 130 is fixed inside the box body, one end of the slide rail 128 is fixed on the slide rail base 130, the other end of the slide rail 128 is connected with the slide base 102, and the slide base 102 can be driven to move relative to the slide rail base 130 by pulling the shelf 100.

As shown in fig. 7, the stopping mechanism in the embodiment of the present invention includes a rotating rod 134 and a top block 132, the rotating rod 134 is hinged to the sliding seat 102, the top block 132 is disposed on the shelf 100, the rotating rod 134 is engaged with the top block 132, so that the sliding seat 102 and the sliding rail 128 can be switched between a locking state where the first ends of the top block 132 and the rotating rod 134 are separated from each other to lock the relative position between the sliding seat 102 and the sliding rail base 130 and an unlocking state where the first ends of the top block 132 and the rotating rod 134 are abutted against each other to unlock the relative position between the sliding seat 102 and the sliding rail base 130.

When the top block 132 is in contact with the rotating rod 134, the sliding seat 102 is movable relative to the sliding rail 128, i.e. the shelf 100 can be pushed back into the cabinet of the refrigerator; when the top block 132 is separated from the rotating lever 134, the sliding seat 102 and the sliding rail 128 are in a locked state, i.e., the shelf 100 cannot be pushed back into the cabinet of the refrigerator.

Specifically, with continued reference to fig. 1, 2 and 4, the rotating rod 134 is hinged to the sliding seat 102, the top block 132 is disposed on the shelf 100, and the top block 132 is engaged with the first end of the rotating rod 134, so that the sliding seat 102 and the sliding rail base 130 are switched between a locking state and an unlocking state, in the locking state, the top block 132 and the first end of the rotating rod 134 are separated from each other, and at this time, the relative position between the sliding seat 102 and the sliding rail base 130 is locked; in the unlocked state, the top block 132 and the first end of the rotating rod 134 are abutted against each other, and at this time, the relative position between the sliding seat 102 and the sliding rail base 130 is adjustable.

The rotating rod 134 is hinged to the sliding seat 102, so that when the first end of the rotating rod 134 is pressed down by the top block 132, the second end of the rotating rod 134 tilts up, at this time, the second end of the rotating rod 134 is not abutted to the sliding rail base 130, and the sliding seat 102 can move relative to the sliding rail base 130. When the top block 132 is separated from the first end of the rotating rod 134, the first end of the rotating rod 134 tilts upward, the second end of the rotating rod 134 moves downward, and at this time, the second end of the rotating rod 134 abuts against the slide rail base 130, so that the slide base 102 is locked with the slide rail base 130 at the relative position. The first end of the rotating rod 134 specifically refers to the left end of the rotating rod 134 shown in fig. 4, and the second end of the rotating rod 134 specifically refers to the right end of the rotating rod 134 shown in fig. 4.

Further, in order to ensure that the second end of the rotating rod 134 can descend by itself and further ensure that the sliding seat 102 cannot be pushed into the box body after the shelf 100 is pulled out, the hinge point of the rotating rod 134 and the sliding seat 102 can be arranged at a position close to the first end of the rotating rod 134. Thus, the distance from the hinge point to the end of the first end of the rotating lever 134 is long, and when the top block 132 is moved away from the first end of the rotating lever 134, the second end of the rotating lever 134 can be lowered by itself under the self-weight of the rotating lever 134.

Further, in order to ensure that the top block 132 and the rotating rod 134 can better cooperate to lock or unlock the relative positions of the sliding seat 102 and the sliding rail base 130, the stopping mechanism in the embodiment of the present invention further includes a connecting rod 136 and a second elastic member (not shown in the figure).

Wherein, the connecting rod 136 is connected to the first end of the rotating rod 134, and a part of the connecting rod 136 penetrates through the upper surface of the sliding seat 102 and corresponds to the position of the top block 132, and the part of the connecting rod 136 penetrates through the upper surface of the sliding seat 102, i.e. the extending section of the connecting rod 136. In addition, the rotating rod 134 and the connecting rod 136 may be integrally formed or may be connected by welding.

The second elastic member may be a spring, and two ends of the second elastic member respectively abut against the upper surface of the sliding seat 102 and the lower surface of the protruding section. That is, the second elastic component supports on sliding seat 102 to the section is stretched out in the ascending jack-up, and so, the second elastic component just can play the supporting role to the first end of dwang 134, and then when kicking block 132 moved away from the first end of dwang 134, the first end of dwang 134 just can upwarp, thereby the second end that drives dwang 134 moves down and supports tightly on slide rail base 130, makes sliding seat 102 and slide rail base 130's relative position locking.

Referring to fig. 1 and 2, the surface of the top block 132 is inclined upward from the middle of the top block 132 to the two ends; from the middle of the connecting bar 136 toward both ends, the surface of the connecting bar 136 is gradually inclined downward.

That is, the top block 132 is formed in a substantially inverted trapezoidal shape and is fixedly installed at the bottom of the shelf 100, and the protruding section of the connecting rod 136 is formed in a shape of a middle protrusion with both sides inclined downward. Thus, when the top block 132 and the protruding section of the connecting rod 136 contact each other, the end of the protruding section of the connecting rod 136 is gradually pressed down by the slope of the trapezoidal top block 132 until the top block 132 is located right above the connecting rod 136. This enables smooth switching of different states of the shelf 100, and prevents the shelf 100 from shaking largely during the state switching.

As shown in fig. 4, two rotation rods 134 may be provided, the two rotation rods 134 are symmetrically hinged to the sliding seat 102 with the central line of the sliding seat 102 as the symmetry axis, and when two rotation rods 134 are provided, the two ends of the connection rod 136 are respectively connected to the first ends of the two rotation rods 134.

As shown in fig. 1 and 6, two avoiding holes 138 are formed in the sliding seat 102, and the protruding sections of the connecting rod 136 respectively protrude through the two avoiding holes 138 and are connected to the first ends of the two rotating rods 134. Of course, the number of the two avoidance holes 138 is corresponding to the number of the rotation rods 134, and when one rotation rod 134 is provided, only one avoidance hole 138 needs to be provided.

Taking avoidance holes 138 as an example, two ends of the extending section on the connecting rod 136 pass through two avoidance holes 138 downwards from the upper side of the two avoidance holes 138 and then are connected with the first ends of the two rotating rods 134, so that the linkage stability of the connecting rod 136 and the rotating rods 134 can be improved when the top block 132 is matched with the connecting rod 136. In addition, the aforementioned second elastic member may be disposed between the upper surface of the portion of the sliding seat 102 between the two relief holes 138 and the lower surface of the protruding section of the connecting rod 136.

Still further, a second end of the rotating rod 134 is provided with a first bending section 140, and an edge of the slide rail base 130 is provided with a second bending section 142 matched with the first bending section 140.

The first bending section 140 may be formed by bending the second end of the rotating rod 134 downward or bending the second end of the rotating rod to two sides, and the second bending section 142 may be formed by bending the edge of the slide rail base 130 upward. When the second end of the rotating rod 134 abuts against the edge of the slide rail base 130, the first bending section 140 and the second bending section 142 abut against each other, so that the stability of the rotating rod 134 abutting against the slide rail base 130 can be further improved.

According to the second aspect of the invention, the storage cabinet comprises a cabinet body and the push-pull shelf assembly, wherein the push-pull shelf assembly is arranged in the cabinet body.

According to the storage cabinet provided by the embodiment of the invention, the push-pull shelf component is arranged in the storage cabinet, so that a user can conveniently rotate the shelf 100 according to the actual use requirement, the user can conveniently store and take articles, and the use of the user is greatly facilitated. In addition, after the shelf 100 is pulled out and rotated, the shelf 100 can be prevented from being pushed back through the stopping structure, and the collision between the shelf 100 and the cabinet body of the storage cabinet is avoided.
