Description

Technical Field

[0001] This utility model relates to the field of warehousing equipment technology, and in particular to a wire rack. Background Technology

[0002] Wire shelving units are a common type of storage equipment, widely used in homes, supermarkets, and warehouses due to their simple structure, good permeability, and flexible adjustability. A typical wire shelving unit usually consists of several vertical support columns and trays whose installation position can be freely adjusted along the height of the support columns.

[0003] To achieve height adjustment of the pallet on the support column, existing technologies typically employ specific fixing structures to secure the load-bearing parts of the pallet to the support column. One common method is to use a tapered sleeve, where the pallet's sleeve holes are pressed down onto the tapered sleeve, relying on the radial friction generated by the tapered surface to fix the pallet to the support column.

[0004] However, this method of fixing pallets, which relies purely on friction, is susceptible to various factors affecting its reliability, such as the smoothness of the mating surfaces, the presence of oil stains, and environmental vibrations. Especially when placing heavy items, the pallet's own weight may exceed the maximum static friction, causing it to slowly slide down the support column or even suddenly fall. This can damage the stored items and, in more serious cases, pose a safety hazard. Therefore, the existing pallet fixing structure for wire shelving still has significant shortcomings in terms of load-bearing capacity and long-term reliability.

[0005] Therefore, this utility model proposes a wire shelf to address the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a wire shelf, which aims to improve the problems of the existing wire shelf's tray fixing structure relying on friction, poor connection reliability, limited load-bearing capacity, and easy slippage under heavy pressure. This utility model aims to provide a wire shelf with an improved structure that can effectively solve the above problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a wire rack, comprising: a rack body and a support column arranged laterally on the rack body, the wire rack further comprising a fixing mechanism for fixing a tray to the support column.

[0008] The fixing mechanism includes a second clamping plate and a first clamping plate disposed opposite to the second clamping plate. The second clamping plate has a mounting portion for fixing in cooperation with the support column. A telescopic rod is also fixedly connected to the second clamping plate. A telescopic cylinder is fixedly connected to the first clamping plate. The telescopic cylinder is slidably sleeved on the outside of the telescopic rod, so that the first clamping plate can slide relative to the second clamping plate.

[0009] The fixing mechanism further includes a screw and a side plate. The shank of the screw passes through the side plate connected to the second clamping plate, and the screw is rotatably abutted against the outer side wall of the side plate connected to the first clamping plate. By rotating the screw, the first clamping plate can be driven to slide relative to each other, thereby achieving clamping and fixing of the tray. Nuts are threaded to both ends of the screw, and the nuts abut against the outer side wall of the side plate.

[0010] Preferably, both the first clamping plate and the second clamping plate are fixedly connected to side plates on opposite side walls.

[0011] Preferably, the wire rack further includes a support mechanism fixedly connected to the bottom of the rack body. The support mechanism includes a first stabilizing block and a second stabilizing block extending along the bottom of the rack body, and the first stabilizing block and the second stabilizing block are fixedly connected.

[0012] Preferably, both the first stabilizing block and the second stabilizing block have fixing grooves on their surfaces facing the shelf body for limiting the shelf body.

[0013] Preferably, the bottom of the first stabilizing block, away from the shelf body, is fixedly connected with an anti-slip pad.

[0014] Preferably, both sides of the first stabilizing block and the second stabilizing block are integrally formed with ear plates.

[0015] Preferably, a fixing screw is threaded onto the ear plate, and the end of the fixing screw can selectively pass through the ear plate to abut against the ground.

[0016] Preferably, the side plate is perpendicular to the surface of the first clamping plate and the surface of the second clamping plate.

[0017] This utility model has the following beneficial effects: 1. In this utility model, a telescopic clamping fixing mechanism consisting of a first clamping plate, a second clamping plate, a telescopic cylinder, a telescopic rod, and a screw is set up. The rotation of the bolt drives the first clamping plate to slide relative to the second clamping plate to clamp the pallet. This solves the problem that in the prior art, shelf pallets are mostly fixed by friction or snap-fit, resulting in poor connection reliability, limited load-bearing capacity, and easy slippage under heavy pressure. The invention achieves the technical effect of large clamping force, firm fixation, and high load-bearing reliability.

[0018] This utility model solves the problems of simple structure, unstable connection with the shelf body, and easy shaking or even tipping of the wire shelf base in the prior art by setting a support mechanism with fixing groove, ear plate and fixing screw at the bottom of the shelf body. The fixing groove limits the shelf body and the fixing screw tightens the connection. This achieves the technical effect of improving the overall structural stability of the shelf and ensuring safe use. Attached Figure Description

Detailed Implementation

[0021] Please refer to Figures 1 to 5 This utility model provides a wire rack, which aims to solve the problems of insufficient reliability and limited load-bearing capacity of the existing pallet fixing structure.

[0022] like Figure 1As shown, the wire rack includes a rack body 1 and a support column 3 arranged horizontally on the rack body 1. The wire rack also includes a fixing mechanism 4 for fixing the tray 2 to the support column 3, and a support mechanism 5 fixedly connected to the bottom of the rack body 1. Specifically, such as Figure 2 , Figure 4 and Figure 5 As shown, the fixing mechanism 4 is the core structure for reliably fixing the pallet 2. The fixing mechanism 4 includes a second clamping plate 402 and a first clamping plate 401 disposed opposite to the second clamping plate 402. The second clamping plate 402 has a mounting part for cooperating with the support column 3 for fixing. This design ensures that the fixing mechanism 4 itself can be stably installed at a predetermined height of the support column 3. To adjust the clamping distance, a telescopic structure is provided between the first clamping plate 401 and the second clamping plate 402. A telescopic rod 404 is fixedly connected to the second clamping plate 402, and a telescopic cylinder 403 is fixedly connected to the first clamping plate 401. The telescopic cylinder 403 is slidably sleeved on the outside of the telescopic rod 404. This slidable sleeve connection method can accurately guide the first clamping plate 401 to slide smoothly relative to the second clamping plate 402, avoiding skewing during the clamping process. To construct the driving and force transmission path, side plates 405 are fixedly connected to the side walls of the first clamping plate 401 and the second clamping plate 402, respectively. The fixing mechanism 4 also includes a screw 406. The rod of the screw 406 passes through the side plate 405 connected to the second clamping plate 402, and both ends of the screw are threaded with nuts. The nuts abut against the outer side wall of the side plate 405. When the screw 406 is rotated, the threaded engagement allows the screw 406 to push the side plate 405 connected to the first clamping plate 401, thereby driving the first clamping plate 401 and the telescopic cylinder 403 to slide along the telescopic rod 404, ultimately achieving precise adjustment and secure locking of the clamping distance between the first clamping plate 401 and the second clamping plate 402.

[0023] The support mechanism 5 includes a first stabilizing block 501 and a second stabilizing block 503 extending along the bottom of the shelf body 1. The first stabilizing block 501 and the second stabilizing block 503 are fixedly connected. The first stabilizing block 501 and the second stabilizing block 503 are both provided with fixing grooves 504 on their surfaces facing the shelf body 1. The fixing grooves 504 are used to precisely limit the installation of the shelf body 1. To enhance anti-slip performance, an anti-slip pad 502 is fixedly connected to the bottom of the first stabilizing block 501 away from the shelf body 1; In order to achieve a secure locking between the shelf body 1 and the support mechanism 5, both sides of the first stabilizing block 501 and the second stabilizing block 503 are integrally formed with ear plates 505. Each ear plate 505 is threaded with a fixing screw 506. The end of the fixing screw 506 can selectively pass through the ear plate 505 to abut against the ground. By rotating the fixing screw 506, the abutting force of the screw end can securely lock the second stabilizing block 503 to the ground.

[0024] In a preferred embodiment, in order to form a stable clamping structure and provide an installation base for the screw 406, the surface of the side plate 405 is perpendicular to the surface of the first clamping plate 401 and the surface of the second clamping plate 402. This perpendicular structural relationship makes the first clamping plate 401, the second clamping plate 402 and the side plate 405 together form a clamping space with a C-shaped profile. As another preferred embodiment, in order to simplify the installation process of the fixing mechanism 4 and the support column 3 and ensure the stability of the connection, the mounting part on the second clamping plate 402 is a U-shaped groove opened on the second clamping plate 402. The outline size of the U-shaped groove is adapted to the outer diameter of the support column 3, so that the fixing mechanism 4 can be conveniently positioned on the support column 3 by lateral snap-in.

[0025] Working principle: When installing and fixing the pallet 2, firstly, the fixing mechanism 4 is positioned and installed at a suitable height on the support column 3 through the mounting part (U-shaped groove) on the second clamping plate 402. Then, the edge of the pallet 2 is placed between the first clamping plate 401 and the second clamping plate 402. At this time, the screw 406 is rotated. Both ends of the screw 406 are threaded with nuts, which abut against the outer side wall of the side plate 405. Since the shank of the screw 406 is threaded through the side plate connected to the second clamping plate 402, the screw 406 is installed in a series of steps. 405. The head of the screw 406 is rotatably abutted against the side plate 405 connected to the first clamping plate 401. Therefore, the rotational motion of the screw 406 is converted into a continuous thrust on the side plate 405 of the first clamping plate 401. This thrust drives the first clamping plate 401, together with the telescopic cylinder 403 fixedly connected to the first clamping plate 401, to slide along the telescopic rod 404 fixedly connected to the second clamping plate 402 towards the second clamping plate 402, and finally achieves a firm clamping of the tray 2. When it is necessary to disassemble or adjust the tray 2, the screw 406 is rotated in the opposite direction. The rod of the screw 406 retracts under the action of the thread, releasing the pushing force on the side plate 405 of the first clamping plate 401. At this time, the first clamping plate 401 can be pulled away from the second clamping plate 402, increasing the clamping space, so that the tray 2 can be easily removed.
