Technical Field

[0001] This utility model belongs to the field of detachable shelving technology, specifically a detachable shelving structure. Background Technology

[0002] Traditional shelving shelves, upper and lower fixed panels, and uprights are all welded together, which results in a large overall size, making transportation inconvenient. The large size also leads to higher freight costs, significantly increasing transportation expenses. Furthermore, during transportation, the starting and stopping of the transportation equipment can easily cause collisions between the shelves, which in severe cases can cause the uprights to tilt and the shelves or fixed plates to deform. Furthermore, the shelves and uprights are welded together, which makes it impossible to adjust the shelf height and make it unsuitable for various usage requirements. Therefore, there is an urgent need to design a detachable shelving structure to solve the above problems. Summary of the Invention

[0003] The purpose of this utility model is to provide a detachable shelving structure, which solves the problems mentioned above, such as the large overall volume of existing traditional shelving, which leads to inconvenience in transportation, high freight costs due to excessive volume, which seriously increases transportation costs, collisions between shelving units during transportation causing uprights to tilt and deform shelves or fixed plates, and the inability to adjust shelf height, making it unsuitable for various usage requirements.

[0004] To solve the above-mentioned technical problems, this utility model provides a detachable shelf structure, including four uprights, a fixed plate, two sets of hanging rack assemblies, and movable shelves. The four uprights are arranged in pairs, with the two uprights in each pair arranged side by side. Several hook limiting grooves for adjusting the height of the hanging rack assemblies are provided on the opposite surfaces of the two sets of uprights. Each of the columns is provided with a fixing connection assembly at its top and bottom. The fixing connection assemblies of two columns arranged side-by-side are positioned opposite each other. Each fixing connection assembly includes two fixing connection plates and several fasteners. One fixing connection plate is attached to the inner side of each column by the fasteners, and the other fixing connection plate is attached to the outer side of each column by the fasteners. The two fixing connection plates are vertically arranged to form a right-angle mounting portion. There are two fixing plates, and their right-angled sides are respectively attached to the right-angle mounting portions above or below the four columns and fixed by the fasteners. The two sets of hanging rack assemblies are respectively arranged opposite each other on the opposite surfaces of the two sets of columns. Each set of hanging rack assemblies consists of several layers of hanging racks arranged vertically at intervals. Each layer of hanging racks in both sets of hanging rack assemblies is at the same height. Several hooks are symmetrically arranged on the side of each hanging rack near the column. Each hook of each hanging rack is matched with the corresponding hook limiting groove. Each hanging rack has a support seat on the side away from the column. The movable shelf has several layers and the same number as each set of hanging rack assemblies. The two ends of each movable shelf are respectively arranged on the support seats of the corresponding hanging racks on the opposite surfaces of the two sets of columns.

[0005] Furthermore, several of the hook limiting grooves are vertically spaced.

[0006] Furthermore, both ends of the fixing plate are provided with a plurality of first threaded holes, and the fixing connecting plates on the inner sides of the two columns in each group are provided with second threaded holes that correspond one-to-one with the first threaded holes.

[0007] Furthermore, the two ends of the fixing plate are provided with clearance holes, which are used to avoid the fasteners.

[0008] Furthermore, each of the hanging racks has four hooks arranged in pairs, with the two pairs of hooks correspondingly disposed on the side wall of each hanging rack near the column, and each hook has an L-shaped vertical cross-section.

[0009] Furthermore, the distance between the two hooks in each group is equal to the distance between the two adjacent hook limiting grooves.

[0010] Furthermore, the hanging bracket, the two sets of hooks, and the support base are integrally formed.

[0011] Furthermore, each of the movable shelves is provided with an open-facing mounting cavity, in which a reinforcing frame is installed. Each of the bottom ends of the reinforcing frame is equipped with a pin, which can be extended to engage with the corresponding hanging bracket for locking.

[0012] The beneficial effects of this utility model are as follows: The shelf structure of this utility model adopts a detachable method to disassemble the shelf into several parts, so that they can be classified, arranged and packaged to reduce the transportation volume of the shelf. While reducing transportation costs, it also avoids wear caused by friction between different parts, and improves the transportation convenience and assembly of the shelf. The hanging rack assembly can be adjusted by coordinating the hanging rack assembly with the hook limit slots at different heights to adjust the height of the movable shelves on the hanging rack and support base, so that it can accommodate the placement of items of different heights and improve the practicality of the shelf. The clearance hole allows the exposed parts of the fasteners used when locking the fixed connecting plate and the column to be avoided, so that the upper and lower fixing plates of the column can fit against the right-angle mounting part formed by the two fixed connecting plates, while also limiting the fixing plate. At the same time, the fasteners are screwed through the second threaded hole and then locked and limited with the first threaded hole on the fixing plate, thereby improving the locking tightness of the fixing plate. The spacing between the two hooks in each group allows each hook to match the limit slots of two adjacent hooks on the column, thus improving the installability of the bracket.

[0013] The pins and their locking mechanism with the hangers ensure that the movable shelves are secured to the hangers after installation, preventing them from detaching from the shelving structure when it is moved. The pins allow the shelves to move freely when released from their locking force, while the locking mechanism effectively prevents the shelves from detaching during use, thus improving the shelving's maneuverability and stability.

Detailed Implementation

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] In one specific embodiment of this utility model, such as Figure 1-3 As shown, a detachable shelving structure is disclosed, including four uprights 1, a fixed plate 3, two sets of hanging rack assemblies 4 and movable shelves 5. The four uprights 1 are arranged in pairs, and the two uprights 1 in each group are arranged side by side. Several hook limiting grooves 11 with adjustable height of hanging rack assembly 4 are opened on the opposite surface of the two sets of uprights 1. The several hook limiting grooves 11 are vertically spaced. Each column 1 is provided with a fixing connection component 2 at its top and bottom. The fixing connection components 2 above or below two columns 1 arranged side by side are positioned opposite each other. Each fixing connection component 2 includes two fixing connection plates 21 and several fasteners 22. One fixing connection plate 21 is attached to the inner side of each column 1 by several fasteners 22, and the other fixing connection plate 21 is attached to the outer side of each column 1 by several fasteners 22. The two fixing connection plates 21 are vertically arranged and form a right-angle mounting part. There are two fixing plates 3, and their right-angled sides are attached to the right-angle mounting parts above or below the four columns 1 and fixed by several fasteners 22. Two sets of hanging rack assemblies 4 are respectively set opposite to each other on the opposite surfaces of the two sets of columns 1. Each set of hanging rack assemblies 4 consists of several layers of hanging racks 41 arranged vertically and vertically. Each layer of hanging racks 41 in the two sets of hanging rack assemblies 4 is at the same height. Several hooks 42 are symmetrically arranged on the side of each hanging rack 41 near the column 1. The hooks 42 of each hanging rack 41 are matched with the corresponding hook limiting grooves 11. Each hanging rack 41 is provided with a support seat 43 on the side away from the column 1. The hanging rack 41, the two sets of hooks 42 and the support seat 43 are integrally formed. The movable shelf 5 has several layers and the same number as each set of hanging rack assemblies 4. The two ends of each movable shelf 5 are respectively set on the support seat 43 of the corresponding hanging rack 41 on the opposite surfaces of the two sets of columns 1. The hanging rack assembly 4 can be adjusted by cooperating with the hook limit slots 11 at different heights to adjust the height of the hanging rack 41 and the movable shelf 5 on the support base 43, so that it can meet the placement of items of different heights and improve the practicality of the shelf.

[0018] The two ends of the fixing plate 3 are provided with a number of first threaded holes 31, and the fixing connecting plate 21 on the inner side of the two columns 1 in each group is provided with second threaded holes 211 that correspond one-to-one with the first threaded holes 31.

[0019] The two ends of the fixing plate 3 are also provided with clearance holes 32. The clearance holes 32 are used to avoid the fasteners 22. The setting of the clearance holes 32 can avoid the exposed part of the fasteners 22 used when the fixing connecting plate 21 is locked to the column 1. This allows the fixing plate 3 at the upper and lower parts of the column 1 to fit with the right angle mounting part formed by the two fixing connecting plates 21, while also limiting the fixing plate 3. At the same time, after the fasteners 22 are screwed through the second threaded hole 211, they are double locked and limited with the first threaded hole 31 on the fixing plate, thereby improving the locking tightness of the fixing plate 3.

[0020] Each hanger 41 has four hooks 42, which are arranged in pairs. The two sets of hooks 42 are respectively set on the side wall of each hanger 41 near the column 1, and the vertical cross section of each hook 42 is L-shaped.

[0021] The distance between the two hooks 42 in each group is equal to the distance between the two adjacent hook limiting grooves 11. The setting of the distance between the two hooks 42 in each group can make the hooks 42 in each group match the two adjacent hook limiting grooves 11 on the column 1, so as to improve the installability of the bracket 41.

[0022] Each movable shelf 5 has an open mounting cavity facing downwards, and a reinforcing frame 6 is installed in the mounting cavity. Both ends of the bottom of the reinforcing frame 6 are equipped with pins 7, which can be extended to cooperate with the corresponding hanging bracket 41 for locking.

[0023] The setting of the pin 7 and its locking mechanism with the bracket 41 can fix the movable shelf 5 to the bracket 41 after installation, so that the movable shelf 5 will not fall off the shelf when the shelf structure is moved. When the movable shelf 5 is released from the locking force of the pin 7, each layer can move. When locked, it can effectively prevent the movable shelf 5 from falling off the shelf during use, thereby improving the controllability and stability of the shelf.

[0024] The shelving structure adopts a detachable design, breaking the shelving down into several components. These components can be categorized, arranged, and packaged to reduce the shelving's transport volume. This reduces transportation costs and avoids wear and tear caused by friction between different components, improving the shelving's transport convenience and ease of assembly.

[0025] The working process of this utility model is as follows: The fixed connection components 2 are installed above and below each column 1 respectively, and the two fixed connection plates 21 of each fixed connection component 2 form a right angle mounting part facing inward. The fixed connection plates 21 are locked to the column 1 by fasteners 22. Then, the clearance holes 32 at both ends of the two fixed plates 3 are fitted onto the outside of the fasteners 22, and the end faces of the two fixed plates 3 abut against the inner side of the right angle mounting part. Then, the fasteners 22 are passed through the second threaded hole 211 on the fixed connection plate 21 and locked with the first threaded hole 31 on the corresponding side of the fixed plate 3. Next, install the hanger 41 on the opposite side of the upright 1. The two hooks 42 on the hanger 41 enter from the opening of the hook limiting groove 11. Then, the groove below the hook 42 is locked onto the locking post formed between the inner wall of the groove and the inner side wall of the upright 1, so as to lock the hanger 41 onto the opposite side of the upright 1. At the same time, the locking position of the hanger 41 and the hook limiting groove 11 on the inner side of the upright 1 can be adjusted according to the required height to change the placement height of the movable shelf 5. After the hanger 41 is installed, place the movable shelf 5 on the support seat 43 of the opposite hanger assembly 4, and insert the pins 7 at both ends of the bottom of the reinforcing frame 6 in the mounting cavity of each movable shelf 5 into the corresponding holes on the hanger 41 to lock it in place, so as to improve the stability and safety of the movable shelf 5 and the shelf.

[0026] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
