Description

Technical Field

[0001] This invention relates to the field of storage equipment technology, and more particularly to a shelf. Background Technology

[0002] In commercial retail environments, automated guided vehicles (AGVs) with spring-loaded pushers are often used to maintain neat and full shelf displays. These ATVs use a spiral spring to pull a pusher at the back; when the front item is removed, the pusher automatically pushes the items behind it to the front.

[0003] However, existing spring-loaded push-plate racks require manual pushing of the pusher to the deepest part of the rack during daily replenishment, while continuously overcoming the reverse thrust of the spring to insert new goods into the tracks. This operation is not only extremely laborious and inefficient, but also carries the risk of the pusher slipping and pinching the operator's hand during placement. Furthermore, the pusher and spring mechanism themselves occupy a fixed depth space at the back of the rack, limiting the actual storage capacity of the rack. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to solve at least one of the technical problems mentioned above.

[0005] The solution to the technical problem of this invention is: a shelf, including a support frame, the support frame including a base and a back panel and uprights both disposed on the base, and further including a load-bearing component, a triggering component, a transmission component, a vibration component, and a clutch component. The load-bearing component includes a shelf, a tray, and an elastic support member. The shelf is disposed on the uprights, the tray is supported on the shelf by the elastic support member, the tray is used to carry goods, the tray is inclined downward from the back panel side away from the back panel, the elastic support member is used to enable the tray to move vertically, and the triggering component is disposed on one side of the base. A transmission assembly is disposed on the back plate, and the input end of the transmission assembly is connected to the trigger assembly. A vibration assembly is disposed on the shelf and located at the bottom of the pallet. The output ends of the vibration assembly and the transmission assembly are connected and drive the pallet to vibrate up and down. A clutch assembly is disposed on the pallet and is used to selectively form or disconnect the vibration transmission engagement between the vibration assembly and the pallet. The trigger assembly is used to receive external forces and drive the vibration assembly to move through the transmission assembly, so that the pallet vibrates up and down, thereby causing the goods on the pallet to slide in an inclined direction under vibration.

[0006] As a further improvement to the above technical solution, the vibration assembly includes a transmission shaft, a first gear, a second gear, a cam, and a stop block. The first gear is rotatably mounted on the edge of the shelf near the back plate and is connected to the output end of the transmission assembly. The transmission shaft is rotatably mounted on the shelf. The second gear is fixedly mounted on the transmission shaft and rotates synchronously with it. The second gear meshes with the first gear. The cam is fixedly mounted on the transmission shaft and rotates synchronously with it. The stop block is located at the bottom of the support plate near the back plate and abuts against the outer contour of the cam, so that when the cam rotates, it drives the stop block to move up and down through its contour surface, thereby causing the support plate to vibrate up and down.

[0007] As a further improvement to the above technical solution, the clutch assembly includes a first guide rail, a second spring, a second guide rail, and a pin. The first guide rail is vertically disposed at the bottom of the support plate. The abutment is slidably connected to the first guide rail. The two ends of the second spring are respectively connected to the abutment and the support plate. The second spring has a tendency to pull the abutment upward toward the lower surface of the support plate, so that when no external force is applied, the abutment moves upward under the tension of the second spring and disengages from the cam. The second guide rail is horizontally disposed at the bottom of the support plate and perpendicular to the first guide rail. The pin is slidably connected to the second guide rail. One end of the pin extends to the outside of the support plate, and the other end of the pin is provided with a first wedge-shaped portion. The abutment is provided with a second wedge-shaped portion that cooperates with the first wedge-shaped portion, so that the pin drives the abutment to move downward against the tension of the second spring and abut against the cam.

[0008] As a further improvement to the above technical solution, the shelf is detachably hung on the column, and a hook is provided at one end of the shelf near the column. The column has a plurality of hanging holes adapted to the hook. Some teeth of the first gear protrude from the edge of the shelf near the back plate, so that when the shelf is hooked into the hanging hole through the hook, the first gear exposed outside the edge of the shelf is connected to the output end of the transmission component.

[0009] As a further improvement to the above technical solution, the triggering component includes a base plate, a support frame, a horizontal rotating shaft, a first connecting rod, a second connecting rod, a pedal, a first spring, and a reset wheel. The base plate is disposed on one side of the base, the support frame is disposed on the base plate, the horizontal rotating shaft is rotatably disposed on the support frame, one end of the pedal is hinged to the base plate, the other end of the pedal is hinged to the first connecting rod, the end of the first connecting rod away from the pedal is hinged to the second connecting rod, the end of the second connecting rod away from the first connecting rod is fixedly sleeved on the horizontal rotating shaft and rotates synchronously with the horizontal rotating shaft, the reset wheel is fixedly sleeved on the horizontal rotating shaft and rotates synchronously with the horizontal rotating shaft, the reset wheel is provided with an eccentric shaft, one end of the first spring is fixedly connected to the eccentric shaft, the other end of the first spring is fixedly connected to the support frame, the first spring has a tendency to pull the eccentric shaft downward, and the horizontal rotating shaft and the input end of the transmission component are connected in a transmission connection.

[0010] As a further improvement to the above technical solution, the transmission assembly includes a rack, a third guide rail, and a third gear. The third guide rail is vertically disposed on the back plate. The rack is slidably connected to the third guide rail. The third gear is fixedly sleeved on the horizontal rotating shaft and rotates synchronously with the horizontal rotating shaft. The third gear meshes with the rack, and the rack is transmittedly connected to the vibration assembly.

[0011] As a further improvement to the above technical solution, there are multiple bearing components, vibration components and clutch components, and they are arranged in a one-to-one correspondence. Multiple bearing components are arranged vertically on the column. The input end of the vibration component is a first gear, and the first gears of all vibration components mesh with the same rack.

[0012] As a further improvement to the above technical solution, the shelf is horizontally arranged, and the angle between the upper surface of the tray and the upper surface of the shelf is 3° to 8°.

[0013] As a further improvement to the above technical solution, the elastic support includes four third springs respectively disposed at the four corners of the lower surface of the tray. The lower end of the third spring is fixed to the upper surface of the shelf, and the upper end of the third spring is fixed to the lower surface of the tray, so that the tray is elastically supported on the upper surface of the shelf, and the tray has an elastic clearance stroke in the vertical direction relative to the shelf to respond to the vibration generated by the vibration assembly.

[0014] As a further improvement to the above technical solution, the supporting component also includes a fence. One bottom end of the fence is provided with a plug-in ear, and the other bottom end of the fence is provided with a buckle. The upper surface of the shelf is provided with a positioning slot and a slot. The plug-in ear is flat and has a notch on one side edge. The plug-in ear is used to insert into the positioning slot, and the notch is used to engage with the wall of the positioning slot to restrict the vertical freedom of the fence. The slot is used to engage with the buckle to achieve detachable locking of the fence.

[0015] The beneficial effects of this invention are as follows: the support frame provides overall structural support; in the load-bearing component, the inclined pallet utilizes gravity to provide potential energy for the sliding of goods, and the elastic support component allows the pallet to have the freedom to vibrate up and down; the trigger component, as the power input end, can receive external forces such as those exerted by operators stepping on it; the transmission component transmits power to the vibration component; the vibration component converts the power into vibration, driving the pallet to vibrate up and down; the clutch component can control the on / off transmission of vibration. By triggering the component and the transmission component to make the vibration component move, the pallet vibrates, breaking the static friction between the goods and the pallet. Under the action of its own weight, the goods slide towards the front end along the inclined direction. When replenishing goods, the operation of pushing the traditional spring-loaded pusher with both hands is eliminated, saving time and effort and avoiding the risk of pinching; after eliminating the spring-loaded pusher mechanism, the storage space of the shelf depth is freed up, increasing the actual display capacity; at the same time, combined with the clutch component, it supports single-layer on-demand replenishment, improving the shelf's sorting efficiency and usage flexibility.

Detailed Implementation

[0023] To more clearly illustrate the technical solutions in the embodiments of the present invention, the accompanying drawings used in the description of the embodiments have been briefly explained above. Obviously, the described drawings are only a part of the embodiments of the present invention, and not all of them. Those skilled in the art can obtain other design schemes and drawings based on these drawings without creative effort.

[0024] The following will clearly and completely describe the concept, specific structure, and technical effects of the present invention in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention. Furthermore, all connections / linkages mentioned herein do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0025] In commercial retail environments, automated guided shelves with wind-up pushers are often used to maintain neat and full shelf displays. However, existing wind-up pusher shelves require manual operation during daily replenishment. The pusher must be manually pushed to the deepest part of the shelf, and the reverse force of the spring must be continuously overcome to insert new products into the track. This operation is not only extremely laborious and inefficient, but also carries the risk of the pusher slipping and injuring the operator's hand during placement. Furthermore, the pusher and the wind-up mechanism themselves occupy a fixed depth space at the back of the shelf, limiting the actual storage capacity of the shelf.

[0026] Therefore, the present invention proposes a shelf, referring to Figures 1-6 The system includes a support frame 100, which includes a base 110, a back plate 120, and a column 130, all mounted on the base 110. It also includes a load-bearing assembly 200, a triggering assembly 300, a transmission assembly 400, a vibration assembly 500, and a clutch assembly 600. The load-bearing assembly 200 includes a shelf 210, a tray 220, and an elastic support member 230. The shelf 210 is mounted on the column 130. The tray 220 is supported on the shelf 210 by the elastic support member 230. The tray 220 carries goods and is inclined downwards from the back plate 120 towards the direction away from the back plate 120. The elastic support member 230 allows the tray 220 to move vertically. The triggering assembly 300 is located on one side of the base 110. The transmission assembly 400 is disposed on the back plate 120. The input end of the transmission assembly 400 is connected to the trigger assembly 300. The vibration assembly 500 is disposed on the shelf 210 and located at the bottom of the pallet 220. The output ends of the vibration assembly 500 and the transmission assembly 400 are connected and drive the pallet 220 to vibrate up and down. The clutch assembly 600 is disposed on the pallet 220. The clutch assembly 600 is used to selectively form or disconnect the vibration transmission engagement between the vibration assembly 500 and the pallet 220. The trigger assembly 300 is used to receive external force and drive the vibration assembly 500 to move through the transmission assembly 400, so that the pallet 220 vibrates up and down, thereby causing the goods on the pallet 220 to slide in the inclined direction under vibration.

[0027] The support frame 100 provides overall structural support; in the load-bearing component 200, the inclined pallet 220 uses gravity to provide potential energy for the sliding of goods, and the elastic support member 230 gives the pallet 220 the freedom to vibrate up and down; the trigger component 300 serves as the power input end and can receive external forces such as those exerted by the operator stepping on it; the transmission component 400 transmits power to the vibration component 500; the vibration component 500 converts the power into vibration, driving the pallet 220 to vibrate up and down; the clutch component 600 can control the on and off of the vibration transmission. The vibration component 500 is activated by triggering component 300 and transmission component 400, which drives the pallet 220 to vibrate, breaking the static friction between the goods and the pallet 220. Under the action of its own weight, the goods slide towards the front end in an inclined direction. When replenishing goods, the operation of pushing the traditional spring-loaded pusher with both hands is eliminated, saving time and effort and avoiding the risk of pinching. After eliminating the spring-loaded pusher mechanism, the storage space of the shelf depth is freed up, increasing the actual display capacity. At the same time, combined with clutch component 600, it supports single-layer on-demand replenishment, improving the shelf's sorting efficiency and usage flexibility.

[0028] The workflow is as follows: When goods need to be sorted, the operator first operates the clutch assembly 600 to make the vibration assembly 500 and the pallet 220 vibrate together. Then, the operator operates the trigger assembly 300, which transmits power to the vibration assembly 500 through the transmission assembly 400. The vibration assembly 500 drives the pallet 220 to vibrate up and down. Under the action of vibration, the friction between the goods on the pallet 220 and the pallet 220 is reduced. Driven by the component of its own weight along the inclined plane, the goods slide from the back plate 120 to away from the back plate 120. After the goods are moved into place, the operator releases the trigger assembly 300, the vibration stops, and the clutch assembly 600 is operated again to disconnect the vibration transmission and complete the replenishment. If a certain layer does not need to be sorted, the clutch assembly 600 of that layer can be operated in advance to disconnect it. At this time, although the trigger assembly 300 is activated, the pallet 220 of that layer will not vibrate and will not interfere with each other.

[0029] Traditional vibration methods may suffer from low vibration transmission efficiency and uneven vibration amplitude of the pallet 220, failing to effectively overcome the static friction between the goods and the pallet 220, resulting in poor sliding during replenishment. Therefore, in one embodiment, the vibration assembly 500 includes a drive shaft 510, a first gear 520, a second gear 530, a cam 540, and a stop block 550. The first gear 520 is rotatably mounted on the edge of the shelf 210 near the back plate 120, for example, by a short shaft and bearing fixed to the edge of the shelf 210. The first gear 520 is connected to the output end of the transmission assembly 400. The drive shaft 510 is rotatably mounted on the shelf 210, and the second gear 530 is fixedly sleeved on it. The first gear 530 rotates synchronously with the first gear 520 on the transmission shaft 510. The second gear 530 meshes with the first gear 520. The cam 540 is fixedly sleeved on the transmission shaft 510 and rotates synchronously with the transmission shaft 510. The abutment 550 is disposed at the bottom of the support plate 220 near the back plate 120. The abutment 550 is used to abut against the outer contour of the cam 540, so that when the cam 540 rotates, it drives the abutment 550 to move up and down through its contour surface, thereby causing the support plate 220 to vibrate up and down. Through the meshing transmission of the first gear 520 and the second gear 530, the power of the transmission assembly 400 is smoothly transmitted to the cam 540 shaft. The cam 540 mechanism composed of the cam 540 and the abutment 550 can convert continuous rotational motion into controllable reciprocating linear vibration, which directly acts on the bottom of the support plate 220. It has high vibration efficiency, compact structure, and is easy to arrange in the narrow space between the shelf 210 and the support plate 220.

[0030] If the vibration component 500 and the pallet 220 are always in a rigid connection state, once triggered, all shelves 210 of the shelf will be forced to vibrate simultaneously. This not only wastes operational kinetic energy, but may also cause goods on fully loaded shelves 210 that do not require replenishment to tip over, become misaligned, or slide out. Therefore, in one embodiment, the clutch component 600 includes a first guide rail 610, a second spring 620, a second guide rail 630, and a pin 640. The first guide rail 610 is vertically disposed at the bottom of the pallet 220. The abutment block 550 is slidably connected to the first guide rail 610. The two ends of the second spring 620 are respectively connected to the abutment block 550 and the pallet 220. The second spring 620 has a tendency to pull the abutment block 550 upward toward the lower surface of the pallet 220, so that when no external force is applied, the abutment block 550 moves upward under the tension of the second spring 620 and disengages from the cam 540. The second guide rail 630 is horizontally disposed at the bottom of the tray 220 and perpendicular to the first guide rail 610. The pin 640 is slidably connected to the second guide rail 630. One end of the pin 640 extends to the outside of the tray 220. The operator can manually push and pull the end of the pin 640 exposed on the outside of the tray 220. The other end of the pin 640 is provided with a first wedge-shaped portion 641. The abutment 550 is provided with a second wedge-shaped portion 642 that cooperates with the first wedge-shaped portion 641, so that the pin 640 drives the abutment 550 to move downward against the tension of the second spring 620 and abut against the cam 540. The cooperation of the first wedge 641 and the second wedge 642 converts the horizontal thrust into a downward vertical pressure, causing the abutment block 550 to move downward against the tension of the second spring 620 and abut against the surface of the cam 540 below, thereby connecting the vibration transmission. When the auxiliary replenishment of this layer is not needed, the reverse operation of the pin 640 causes it to retract away from the abutment block 550. At this time, the wedge cooperation is released, and the elastic force of the second spring 620 immediately pulls the abutment block 550 upward, making the abutment block 550 suspended and completely separated from the cam 540. This achieves physical isolation and independent control of the vibration state of a single layer of shelving, improving the accuracy and flexibility of equipment use.

[0031] Considering the varying height requirements of each layer of a multi-tiered shelving unit, a fixed position for each shelf panel 210 would not flexibly accommodate goods of different heights. Therefore, in one embodiment, the shelf panel 210 is detachably mounted on the upright 130. A hook 211 is provided at one end of the shelf panel 210 near the upright 130. The upright 130 has multiple hanging holes 212 that mate with the hook 211. Part of the teeth of the first gear 520 protrude from the edge of the shelf panel 210 near the back plate 120, so that when the shelf panel 210 is hooked into the hanging hole 212 via the hook 211, the first gear 520 exposed outside the edge of the shelf panel 210 is connected to the output end of the transmission assembly 400. By engaging the hooks 211 with the array of hanging holes 212 on the uprights 130, tool-free quick assembly and disassembly of the shelf 210 and arbitrary height adjustment are achieved. The first gear 520 protrudes from the rear edge of the shelf 210, ensuring accurate meshing with the rack 410 in the transmission assembly 400 on the back panel 120 when the shelf 210 is hooked into the uprights 130. This achieves simultaneous engagement of structural load-bearing locking and power transmission, simplifying the process for store staff to change shelf layouts. To ensure that the first gear 520 protruding from the edge of the shelf 210 always correctly meshes with the rack 410 of the transmission assembly 400 when the shelf 210 is hooked into hanging holes 212 at different heights via the hooks 211, the vertical center distance between two adjacent hanging holes 212 is set to be equal to the tooth pitch of the rack 410 multiplied by a positive integer N, where N≥1. Thus, when the shelf 210 moves up or down by one mounting hole 212 position, the axis of the first gear 520 also moves synchronously by an integer multiple of the tooth pitch, thereby ensuring that the teeth of the first gear 520 and the tooth grooves of the rack 410 are always in the correct meshing phase, avoiding tooth tip interference or disengagement. In addition, the tooth width of the first gear 520 is designed to be greater than the tooth width of the rack 410 to allow for slight installation errors in the mounting direction of the shelf 210, i.e., the direction perpendicular to the back plate 120.

[0032] The cumbersome operation of the trigger component 300 can affect replenishment efficiency and user experience. Therefore, in one embodiment, the trigger component 300 includes a base plate 310, a support frame 320, a horizontal pivot 330, a first connecting rod 340, a second connecting rod 350, a pedal 360, a first spring 370, and a return wheel 380. The base plate 310 is disposed on one side of the base 110, the support frame 320 is disposed on the base plate 310, the horizontal pivot 330 is rotatably disposed on the support frame 320, one end of the pedal 360 is hinged to the base plate 310, the other end of the pedal 360 is hinged to the first connecting rod 340, and the end of the first connecting rod 340 away from the pedal 360 is connected to the second connecting rod 350. The second connecting rod 350 is hinged at 350 degrees. The end of the second connecting rod 350 furthest from the first connecting rod 340 is fixedly sleeved on the horizontal rotating shaft 330 and rotates synchronously with the horizontal rotating shaft 330. The reset wheel 380 is fixedly sleeved on the horizontal rotating shaft 330 and rotates synchronously with the horizontal rotating shaft 330. An eccentric shaft 381 is provided on the reset wheel 380. One end of the first spring 370 is fixedly connected to the eccentric shaft 381, and the other end of the first spring 370 is fixedly connected to the support frame 320. The first spring 370 has a tendency to pull the eccentric shaft 381 downwards. The horizontal rotating shaft 330 and the input end of the transmission assembly 400 are connected in a transmission connection. A 360-degree pedal trigger mechanism is adopted, allowing the operator to easily step on it with their foot, conforming to ergonomics and freeing their hands for replenishment operations. The linkage mechanism converts the swing of the pedal 360 into the rotation of the horizontal shaft 330. The cooperation between the reset wheel 380 and the first spring 370 can reset the entire trigger assembly 300 to its initial state after the operator releases the pedal 360, waiting for the next operation, thus ensuring the continuous availability and ease of operation of the system.

[0033] If the transmission assembly 400 has a complex structure or unstable transmission, it may cause asynchronous vibration of the multi-layer shelving. Therefore, in one embodiment, the transmission assembly 400 includes a rack 410, a third guide rail 420, and a third gear 430. The third guide rail 420 is vertically mounted on the back plate 120. The rack 410 is slidably connected to the third guide rail 420. The third gear 430 is fixedly mounted on the horizontal rotating shaft 330 and rotates synchronously with the horizontal rotating shaft 330. The third gear 430 meshes with the rack 410, and the rack 410 is drive-connected to the vibration assembly 500. When the third gear 430 rotates under the drive of the bottom horizontal rotating shaft 330, the meshing rack 410 is pushed upward or pulled downward, and makes a smooth linear lifting and lowering motion in the vertical direction under the constraint of the third guide rail 420. The gear and rack 410 transmission has the advantage of strong load-bearing capacity. With the limiting of the third guide rail 420, it reduces the structural skew or bending jamming during long-distance power transmission, and ensures the efficient and smooth transmission of power from the bottom layer to the upper layer 210.

[0034] For multi-layer shelving, requiring independent power input for each layer would result in complex structure and high cost. Therefore, in one embodiment, multiple load-bearing components 200, vibration components 500, and clutch components 600 are arranged in a one-to-one correspondence. Multiple load-bearing components 200 are vertically mounted on the upright 130. The input end of each vibration component 500 is a first gear 520, and all the first gears 520 of the vibration components 500 mesh with the same rack 410. By using a shared rack 410 to simultaneously drive the vibration components 500 on multiple shelves 210, a single-point triggering and multi-layer linkage effect is achieved. This simplifies the number of mechanical parts in the back panel 120 area, reduces the overall weight and manufacturing cost of the equipment, and ensures synchronous response of each shelf layer when receiving power when the clutch is engaged.

[0035] If the tilt angle of the pallet 220 is too small, the sliding resistance of the goods will be large; if the angle is too large, the goods may impact the front shelf or tip over due to excessive acceleration due to gravity. Therefore, in one embodiment, the shelf 210 is horizontally arranged, and the angle between the upper surface of the pallet 220 and the upper surface of the shelf 210 is 3° to 8°. The small tilt angle of 3° to 8° ensures that the goods can be firmly and stably placed deep in the shelf without slipping when there is no vibration, and also ensures that when vibration is triggered, the goods can slide towards the front of the shelf at a uniform speed and smoothly by the weight component they release, avoiding uncontrolled impact and maximizing the protection of the integrity and aesthetic appearance of the goods.

[0036] When the pallet 220 carries a heavy load and enters a vibration state, corner collapse, tipping, or resonance tilting may occur, causing the goods to fall over. Therefore, in one embodiment, the elastic support 230 includes four third springs 231 respectively disposed at the four corners of the lower surface of the pallet 220. The lower end of the third spring 231 is fixed to the upper surface of the shelf 210, and the upper end of the third spring 231 is fixed to the lower surface of the pallet 220, so that the pallet 220 is elastically supported on the upper surface of the shelf 210, and the pallet 220 has an elastic clearance stroke in the vertical direction relative to the shelf 210 to respond to the vibration generated by the vibration assembly 500. The third springs 231 are evenly distributed at the four corners of the bottom of the pallet 220 to provide uniform and stable elastic support for the pallet 220, ensuring that the pallet 220 can remain horizontal when bearing uneven load weight; at the same time, it provides vertical movement guidance for the pallet 220, enabling it to vibrate vertically in response to the drive of the vibration assembly 500.

[0037] During the dynamic process of goods being vibrated and sliding downwards, they may slip off the edges of the pallet 220 and fall, causing damage to the goods. Therefore, in one embodiment, the supporting component 200 further includes a guardrail 240. One bottom end of the guardrail 240 is provided with a plug-in lug 241, and the other bottom end of the guardrail 240 is provided with a buckle 242. The upper surface of the shelf 210 is provided with a positioning slot 243 and a slot 244. The plug-in lug 241 is flat, and one edge of the plug-in lug 241 is provided with a snap-fit ​​notch 245. The plug-in lug 241 is used to insert into the positioning slot 243, and the snap-fit ​​notch 245 is used to engage with the hole wall of the positioning slot 243 to restrict the vertical freedom of the guardrail 240. The slot 244 is used to engage with the buckle 242 to realize the detachable locking of the guardrail 240. The fence 240 prevents goods from laterally deviating or accidentally slipping off the front end during vibration and sliding. During installation, simply insert the flat plug-in ear 241 diagonally into the positioning slot 243 and use the snap-fit ​​notch 245 to lock the hole wall to instantly lock multiple spatial degrees of freedom at one end of the fence 240. Then, press the buckle 242 at the other end into the slot 244 to complete the full locking. This achieves tool-free, second-level quick assembly and disassembly of the fence 240, ensuring the sturdiness of the fence and facilitating the daily cleaning and maintenance of the shelving.
