Description

Technical Field

[0001] The present invention generally relates to the technical field of storage display devices, and in particular to a detachable shelf and a shelf installation and removal device. Background Art

[0002] Commercial shelves, or home furniture such as bookcases and cabinets, all require internal shelves to place items and improve space utilization. There are two specific shelf installation structures: fixed and pull-out. In the fixed structure, the shelves are inseparable from the external frame after installation. In the pull-out structure, the shelves can slide relative to the external frame. When using the pull-out structure, the user needs to pull the shelves out of the external frame along the track. To prevent the shelves from sliding freely in the track and affecting the stability of the structure, locking pins are usually provided in existing structures. Under normal circumstances, the shelves are locked to the track. When the shelves need to be pulled out, such as during cargo inspection and inventory, the operator needs to manually open the locking pins to allow the shelves to move relative to the track. However, the spatial range defined by the shelves is limited, making it inconvenient for operators to operate. Furthermore, this manual opening and locking method is difficult to manage automatically, hindering the further development of the mall's automation business. Therefore, improvements to the shelves are needed.

[0046] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0047] Figure 1 FIG. 1 shows a specific structure of a detachable layer plate 100 according to a preferred embodiment of the present invention. Figure 2 The specific structure of the unlocking mechanism 130 according to a preferred embodiment of the present invention is shown below. Figure 1 and Figure 2 Detailed description.

[0048] like Figure 1 As shown, the detachable layer 100 includes a layer 110, a locking pin 120, an unlocking mechanism 130 and a connecting rod 140, wherein the layer 110 is a pull-out layer that can be moved along a preset track ( Figure 1 In order to prevent the layer plate 110 from sliding randomly in the track and affecting the safety of the structure, a locking pin 120 is further provided in this embodiment. The locking pin 120 is arranged on the side of the layer plate 110, and the locking pin 120 is detachably connected to the track. When the locking pin 120 is connected to the track, the relative position of the layer plate 110 and the track is fixed and cannot slide. When the locking pin 120 is separated from the track, the layer plate 110 can slide along the track, which is convenient for removing or installing the layer plate.

[0049] Furthermore, according to a preferred embodiment of the present invention, the locking pin 120 includes a pull ring 121 and a plunger 122. The pull ring 121 is connected to the plunger 122. A spring is also provided inside the locking pin 120. When the pull ring 121 is pulled, the plunger 122 moves with the pull ring 121, and the spring inside the locking pin 120 obtains elastic potential energy. Figure 3 As shown, the locking pin 120 is arranged on the side of the layer plate 110. In some embodiments of the present invention, the track is provided with a countersunk hole or a through hole at a preset position. The plunger 122 in the locking pin 120 is in the spring ( Figure 3The locking pin 120 can also be configured as a clamping and locking structure, for example, the locking pin 120 has one or more movable ends, which are clamped on the track or the matching structure of the track under the action of the pull ring 121. The movable ends are clamped on the track or the matching structure of the track under the action of the pull ring 121, and the movable ends are released from the track. When the external force applied to the pull ring 121 is eliminated, the plunger 122 abuts against the side of the track under the action of the spring, and moves with the track to the countersunk hole or the through hole. The plunger 122 is driven by the spring to insert into the countersunk hole or the through hole, and the relative position relationship between the track and the track is locked, and the track 110 cannot be moved.

[0050] The unlocking mechanism 130 is provided on the deck 110. The two ends of the connecting rod 140 are connected to the locking pin 120 and the unlocking mechanism 130 respectively. The unlocking mechanism 130 can drive the locking pin 120 to separate from the track. The unlocking mechanism 130 drives the connecting rod 140 to move, and then drives the locking pin 120 to move, thereby achieving locking and unlocking of the deck 110 and the track. Specifically, the unlocking mechanism 130 in this embodiment is as follows: Figure 2 As shown, the unlocking mechanism 130 includes a mechanism body 131, an active member 132, and a driven member 133, wherein the mechanism body 131 is fixedly connected to the deck 110, the active member 132 is hinged to the mechanism body 131, and the driven member 133 is hinged to the active member 132. The driven member 133 is also hinged to the connecting rod 140. When the active member 132 moves, it drives the hinged driven member 133, which drives the connecting rod 140 to move, thereby driving the locking pin 120 to separate from the track, thereby unlocking the deck 110 from the track. According to a preferred embodiment of the present invention, when the external force applied to the active member 132 is eliminated, the locking pin 120 returns to a locked state with the track or abuts against the track under the action of its own structure.

[0051] In a preferred embodiment of the present invention, the specific structure of the unlocking mechanism 130 is as follows: Figure 2 As shown, the active member 132 includes a handle 1321 and a first connecting rod 1322, wherein the handle 1321 is fixedly connected to the first connecting rod 1322, and the middle portion of the first connecting rod 1322 is hinged to the mechanism body 131. The handle 1321 is a structure that facilitates manual or mechanical operation. Under the action of an external force, the handle 1321 moves, and accordingly, the first connecting rod 1322 rotates about the hinged position with the mechanism body 131. Specifically, when the handle 1321 moves under the action of an external force, the first connecting rod 1322, which is fixedly connected to the handle 1321, moves accordingly, wherein the direction of movement of the end of the first connecting rod 1322 away from the handle 1321 is opposite to the rotation direction of the handle 1321.

[0052] like Figure 2 As shown, the follower 133 includes a second link 1331 and a third link 1332, wherein one end of the second link 1331 is hinged to the end of the first link 1322 away from the handle 1321, and the two ends of the third link 1332 are hinged to the first link 1322 and the end of the second link 1331 away from the first link 1322, respectively. The connecting rod 140 is hinged at the hinge position of the second link 1331 and the third link 1332. The hinge position of the second link 1331 and the third link 1332 moves under the drive of the handle 1321, thereby driving the connecting rod 140 hinged thereto to move, thereby achieving control of the locking pin 120.

[0053] According to a preferred embodiment of the present invention, Figure 1 and Figure 2 As shown, there are two sets of locking pins 120, which are respectively arranged on the two sides of the layer plate 110. There are two connecting rods 140, which cooperate with the two sets of locking pins 120. Accordingly, there are two sets of handles 1321, first connecting rods 1322, second connecting rods 1331 and third connecting rods 1332 in the active member 132 and the driven member 133, respectively, which correspond one-to-one with the two sets of locking pins 120. Furthermore, the first connecting rods 1322 in the two sets of active members 132 are hinged at the same position of the mechanism body 131. According to a preferred embodiment of the present invention, the two sets of first connecting rods 1322 are in a scissor-shaped configuration. When the two handles 1321 move toward the middle under the action of an external force, the end of the first connecting rod 1322 away from the handle 1321 also moves toward the middle. The second link 1331 in any group of follower members 133 is parallel to the one of the two first links 1322 that is not hinged to it, and the third link 1332 is parallel to the one of the two first links 1322 that is not hinged to it. The two groups of active members 132 and follower members 133 form two parallelogram structures. When the handle 1321 moves toward the middle under the action of external force, the hinge position of the second link 1331 and the third link 1332 moves toward the middle, driving the connecting rod 140 hinged at this position to move.

[0054] According to a preferred embodiment of the present invention, the follower 133 further includes a fourth connecting rod 1333. Figure 2 As shown, one end of the fourth link 1333 is connected to the hinge position of the second link 1331 and the third link 1332, and the other end of the fourth link 1333 is connected to the connecting rod 140. The two ends of the fourth link 1333 can be hinged or fixed, and its function is to drive the connecting rod 140 to move with the second link 1331 and the third link 1332.

[0055] like Figure 2As shown, in a preferred embodiment of the present invention, a waist-shaped through hole 1311 is provided on the mechanism body 131, and the hinge position of the second connecting rod 1331 and the third connecting rod 1332 is restricted in the waist-shaped through hole 1311, that is, the hinge position of the second connecting rod 1331 and the third connecting rod 1332 can only move in the direction of the waist-shaped through hole. Furthermore, the direction of the waist-shaped through hole 1311 is collinear or parallel with the locking pin 120 to ensure that the partial movement in the direction of the locking pin 120 is as large as possible, thereby allowing the handle 1321 to move a small distance to unlock the locking pin 120. At the same time, the collinearity of the waist-shaped through hole 1311 and the locking pin 120 can prevent the connecting rod 140 from pulling the locking pin 120 obliquely, causing excessive side resistance of the locking pin 120, resulting in difficulty in unlocking or structural locking.

[0056] like Figure 1 and Figure 2 As shown, according to a preferred embodiment of the present invention, the mechanism body 131 also has a matching structure 1312 for matching with the layer board removal and installation device to drive the layer board 110 to move along the track. The specific matching method of the matching structure 1312 and the layer board removal and installation device will be described in detail in the subsequent embodiments. Figure 5 Detailed description.

[0057] The present invention also includes an embodiment of a shelf installation and removal device 200, which is used to cooperate with the aforementioned detachable shelf 100 to achieve the installation and removal of the shelf 110. The shelf installation and removal device 200 includes a device body 210, a handle pressing structure 220 and a gripping structure 230, wherein the device body 210 is arranged on a side of the unlocking mechanism 130 having an active part 132, so as to facilitate applying an external force to the active part 132 to achieve unlocking of the locking pin 120. Specifically, for example, the unlocking mechanism 130 is arranged above the interior of the shelf 110, and the active part 132 faces above the shelf 110, and the device body 210 is arranged above the corresponding position of the active part 132, such as Figure 5 shown.

[0058] The handle pressing structure 220 is provided on the device body 210 and can be driven to drive the active member 132 to move, or to move away from the active member 132, so as to Figure 2 Taking the unlocking mechanism 130 shown as an example, the handle pressing structure 220 in this embodiment can act on the handle 1321, squeezing the handle 1321 to make the handle 1321 move toward the middle, and then the connecting rod 140 drives the locking pin 120 to unlock, but the handle pressing structure 220 in this embodiment is not directly connected to the handle 1321. When the handle pressing structure 220 moves outward, the handle 1321 is separated from the handle pressing structure 220.

[0059] The gripping structure 230 is disposed on the device body 210, and the relative position of the gripping structure 230 and the handle pressing structure 220 is fixed, that is, when the handle pressing structure 220 moves relative to the active member 132, the positional relationship between the gripping structure 230 and the mechanism body 131 also changes accordingly. Specifically, when the handle pressing structure 220 is driven to move to a preset position, the gripping structure 230 is fixedly connected to the unlocking mechanism 130. According to a preferred embodiment of the present invention, when the handle pressing structure 220 drives the active member 132 to move to release the locking relationship between the locking pin 120 and the track, the unlocking mechanism 130 is fixedly connected to the gripping structure 230. In this case, controlling the movement of the layer board installation and removal device 200 can drive the layer board 110 to move along the track, thereby realizing the automated installation and removal of the layer board 110.

[0060] As described in the above embodiment, the unlocking mechanism 130 is further provided with a matching structure 1312 on the mechanism body 131, and the matching structure 1312 can match with the grabbing structure 230. Under the action of the handle pressing structure 220, after the locking pin 120 is unlocked from the track, the grabbing structure 230 is fixedly connected to the matching structure 1312, for example, by snapping, or as shown in FIG. Figure 5 As shown, the mating structure 1312 extends outward, and the gripping structure 230 has a matching groove. The mating structure 1312 is inserted into the groove. When the shelf installation and removal device 200 is driven to move, the gripping structure 230 drives the mating structure 1312, and in turn drives the shelf 110 to move, thereby automatically controlling the installation and removal process of the shelf 110. For example, in the application scenario of store shelves, the shelf installation and removal device 200 can replace manual operation to pull out the shelf 110, providing convenience for cargo inspection and inventory.

[0061] According to a preferred embodiment of the present invention, the specific structure of the layer installation and removal device 200 is as follows: Figure 4 As shown, the layer installation and removal device 200 further includes a guide rail 240, which is provided on the device body 210, and the handle pressing structure 220 and the grasping structure 230 are slidably provided on the guide rail 240, and the guide rail 240 is used to limit the movement direction of the handle pressing structure 220 and the grasping structure 230. Further, the guide rail 240 is parallel to the locking pin 120, as shown in FIG. Figure 5 As shown, the handle pressing structure 220 moves in a direction parallel to the locking pin 120 , driving the handle 1321 to move in the same direction, and driving the locking pin 120 to unlock from the track through the follower 133 and the connecting rod 140 .

[0062] Specifically, the locking pins 120 in this embodiment have two groups and are respectively arranged on both sides of the layer 110. The connecting rod 140 and the active part 132 and the driven part 133 in the unlocking mechanism 130 also have two groups. Similarly, the handle pressing structure 220 and the grabbing structure 230 in the layer installation and removal device 200 also have two groups, and both correspond one-to-one to the two groups of locking pins 120.

[0063] According to a preferred embodiment of the present invention, the unlocking mechanism 130 is arranged in the middle position of the layer plate 110, and a matching structure 1312 is provided on both sides. The position of the layer plate installation and removal device 200 corresponds to the position of the unlocking mechanism 130, and has two grasping structures 230 that cooperate with the matching structures 1312 on both sides of the unlocking mechanism 130 to ensure that the forces on both sides of the layer plate 110 are balanced during the insertion and extraction process, thereby avoiding the layer plate 110 from tilting relative to the track, causing the structure to be stuck.

[0064] like Figure 4 As shown, the layer installation and removal device 200 also includes a driving device 250, an eccentric wheel 260 and two transmission rods 270, wherein the driving device 250 provides power for the handle pressing structure 220 to move along the guide rail 240, such as an electric motor or an industrial steering gear, and the eccentric wheel 260 is fixedly connected to the output shaft of the driving device 250. The eccentric wheel 260 has two eccentric shafts 261, and the eccentric shafts 261 rotate as the output shaft of the driving device 250 rotates. One end of the two transmission rods 270 is hinged to the eccentric shaft 261 of the eccentric wheel 260.

[0065] In this embodiment, the handle pressing structure 220 and the gripping structure 230 are fixedly connected and integrally formed to form a fixed structure. The fixed structure (composed of the handle pressing structure 220 and the gripping structure 230) comprises two sets, each of which is movable along the guide rail 240. The ends of the two transmission rods 270, distal from the eccentric shaft 261, are each hingedly connected to a fixed structure. When the drive device 250 rotates, it drives the eccentric wheel 260, and the transmission rods 270 move with the eccentric shaft 261, causing the two fixed structures to move toward or away from each other. This, in turn, causes the handle pressing structure 220 to move toward or away from the active member 132 of the unlocking mechanism 130, causing the locking pin 120 to separate from or connect to the track.

[0066] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
