Description

Technical Field

[0001] The utility model relates to the technical field of compact shelves, in particular to a high-strength column of a compact shelf. Background Technique

[0002] A compact shelf is an efficient file storage device that optimizes space through movable racks, facilitating the management and retrieval of items such as files. The columns of a compact shelf are the main load-bearing components that are perpendicular to the ground and support the entire rack structure. The columns of a compact shelf need to be of high strength because they must bear the static weight of the rack and the dynamic loads during daily use. Only with sufficient strength and rigidity can the columns of a compact shelf ensure the stability and durability of the compact shelf and ensure the safe storage and efficient management of items. There are manufacturers in the market that produce columns of compact shelves by setting convex ribs on the bottom plate to increase strength. However, only setting convex ribs on the bottom plate has a rather limited improvement in the overall stress and rigidity of the columns of a compact shelf, and it is difficult to meet the actual needs of production and life.

[0003] After retrieval, the existing patent (publication number: CN208371277U) discloses a "column of a compact shelf, including a main body, the main body is composed of a bottom plate and two side plates, the two side plates are connected to the two side edges in the width direction of the bottom plate and form a groove, the upper ends of the two side plates are respectively bent inward by 90 degrees to form flanges, the bottom plate is provided with a first convex rib formed by stamping, and two second convex ribs formed by stamping are arranged on the first convex rib. The longitudinal section of the second convex rib is in an inverted V shape, and the two second convex ribs are symmetrically arranged with respect to the center line of the bottom plate. The utility model greatly improves the strength of the main body by setting the first convex rib and the second convex rib. Compared with the traditional column structure, it can be improved by more than twice. In addition, by setting the second convex rib, the overall appearance of the column is also increased, making the shape more beautiful."

[0004] Although the patent technology strengthens the column strength by setting the first convex rib and the second convex rib on the bottom plate, it does not strengthen the structure of the side plate and the inside of the column, resulting in the need to improve the overall bearing capacity. Therefore, those skilled in the art provide a high-strength column of a compact shelf to solve the problems raised in the above background technique. Content of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages existing in the prior art, and a high-strength column of a compact shelf is proposed. The column is formed by bending an integrated steel plate into a main board and side plates and cooperating with flanges to increase the structural strength. The first reinforcing rib, the second reinforcing rib and the pattern reinforcing rib are set to improve the local strength and anti-torsion ability. Multiple mounting holes and hanging holes are set to achieve flexible installation. In particular, an internal support structure is set to provide multiple internal support points and anti-impact buffering ability for the column, thereby overall improving the stability, rigidity and bearing capacity of the column of the compact shelf.

[0006] To achieve the above object, the utility model provides the following technical solutions: A high-strength dense rack column, including a main board, two side boards and an internal strengthening structure. The main board and the two side boards are bent from the same steel plate. The upper ends of the two side boards are respectively bent inward by 180 degrees to form flanges. The internal strengthening structure is fixedly arranged through the column internally. The internal strengthening structure includes a round tube, a plurality of first supports and a plurality of second supports;

[0007] Through the above technical solutions, the main board and the two side boards are bent from the same steel plate, reducing the connection points and avoiding the decrease in stability caused by poor welding. The flanges effectively improve the plastic flow of the material, avoiding cracking or wrinkling and thus improving stability. The internal strengthening structure effectively disperses stress by increasing the support points inside the column, avoiding the column from being distorted or bent under heavy loads.

[0008] Further, two first reinforcing ribs are axially symmetrically and fixedly arranged by stamping into the column internally at positions near the front and rear edges of the lower end of the main board, and a pattern reinforcing rib is axially fixedly arranged by stamping into the column internally at the lower end of the main board;

[0009] Through the above technical solutions, the two first reinforcing ribs significantly improve the local strength of the main board when bearing large loads or concentrated forces and effectively disperse stress. The pattern reinforcing rib not only increases a certain aesthetic effect but also effectively increases the anti-torsion ability of the main board.

[0010] Further, a first mounting hole is penetrated and opened at a position near one side edge of the lower end of the main board, a third mounting hole and a fourth mounting hole are sequentially penetrated and opened at a position near the other side edge of the lower end of the main board, and a second mounting hole is penetrated and opened at a position deviated to the other side at the center position of the lower end of the main board;

[0011] Through the above technical solutions, when in use, users can conveniently install other components of the dense rack through the first mounting hole, the second mounting hole, the third mounting hole and the fourth mounting hole according to actual needs.

[0012] Further, two second reinforcing ribs are axially symmetrically and fixedly arranged by stamping into the column internally at positions near the upper and lower edges of the front and rear ends of the two side boards;

[0013] Through the above technical solutions, the two second reinforcing ribs significantly improve the local strength of the two side boards when bearing large loads or concentrated forces and effectively disperse stress, and at the same time help to improve the overall rigidity and stability of the column.

[0014] Further, a plurality of hanging holes are sequentially opened axially through the front and rear ends of the two side boards respectively, and a fifth mounting hole is opened at a position near one side edge of the front and rear ends of the two side boards respectively;

[0015] With the above technical solution, during use, the user can customize the hanging holes of the hanging board at different positions, and at the same time, according to actual needs, the user can conveniently install other components of the compact rack through the fifth mounting hole.

[0016] Furthermore, the circular tube is fixedly arranged at the central position inside the column along the axial direction of the column. The lower ends of multiple first supports are fixedly arranged at the upper end of the main board in sequence along the axial direction, the upper ends of multiple first supports are fixedly arranged at the lower end of the circular tube in sequence along the axial direction, and multiple second supports respectively and sequentially stagger the hanging holes to fixedly connect the inner surfaces of the two side plates and the outer surface of the circular tube;

[0017] With the above technical solution, the circular tube is fixedly arranged at the central position inside the column to provide a firm central support. Multiple first supports and second supports evenly disperse the load applied to the column during use to avoid local stress concentration. In particular, by increasing multiple internal support points, the overall rigidity and bearing capacity of the column are significantly improved, effectively preventing the column from twisting or bending when being impacted.

[0018] Furthermore, the circular tube is made of engineering plastic material, and multiple first supports and multiple second supports are made of polyurethane material;

[0019] With the above technical solution, the circular tube made of engineering plastic material significantly reduces the weight of the column on the premise of ensuring the structural strength, improves the convenience of transportation and installation and use by the user, and at the same time reduces the load brought by the self-weight of the compact rack. The polyurethane material used for multiple first supports and second supports has excellent elasticity and buffering performance, providing a good role in absorbing impact and damping for the column.

[0020] The utility model has the following beneficial effects:

[0021] 1. A high-strength compact rack column proposed by the utility model. The column provides a firm central support by setting the circular tube and uses multiple first supports and multiple second supports to evenly disperse the load applied to the column during use to avoid local stress concentration. The internal strengthening structure increases multiple internal support points, thus significantly improving the overall rigidity and bearing capacity of the column.

[0022] 2. A high-strength compact rack column proposed by the utility model. The column effectively improves the local strength and anti-torsion ability of the main board and the two side plates by setting the first reinforcing rib, the second reinforcing rib and the pattern reinforcing rib, not only ensuring the aesthetics and stability of the column, but also further improving the overall anti-wear and anti-fatigue abilities of the column.

[0023] 3. A high-strength dense rack column proposed by the present utility model. The column is formed by bending the main board and two side boards from the same steel plate, reducing the connection points and avoiding the decrease in stability caused by poor welding. The flanging effectively improves the plastic flow of the material, avoiding cracking or wrinkling, thereby improving stability and rigidity. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Referring to Figures 1-4 , an embodiment provided by the present utility model: A high-strength dense rack column includes a main board 1, two side boards 2, and an internal reinforcing structure 7. The main board 1 and the two side boards 2 are formed by bending the same steel plate, reducing the connection points and avoiding the decrease in stability caused by poor welding. The internal reinforcing structure 7 effectively disperses stress by increasing the support points inside the column, avoiding the column from being distorted or bent under heavy loads.

[0032] The main board 1 and the two side plates 2 are bent from the same steel plate. At the lower end of the main board 1, two first reinforcing ribs 4 are axially symmetrically and fixedly arranged by stamping into the inside of the column along the front and rear edge positions near the two front ends. A pattern reinforcing rib 6 is axially fixedly arranged by stamping into the inside of the column at the lower end of the main board 1. The two first reinforcing ribs 4 significantly improve the local strength of the main board 1 when bearing large loads or concentrated forces and effectively disperse the stress. The pattern reinforcing rib 6 not only increases a certain aesthetic effect but also effectively increases the anti-torsion ability of the main board 1.

[0033] A first mounting hole 8 is penetrated and provided at a position near one side edge at the lower end of the main board 1. A third mounting hole 10 and a fourth mounting hole 11 are sequentially penetrated and provided at a position near the other side edge at the lower end of the main board 1. A second mounting hole 9 is penetrated and provided at a position deviated to the other side at the center position at the lower end of the main board 1. During use, other components of the compact shelf can be conveniently installed by the user through the first mounting hole 8, the second mounting hole 9, the third mounting hole 10, and the fourth mounting hole 11 according to actual needs.

[0034] Flanges 3 are formed by bending the upper ends of the two side plates 2 inwards by 180 degrees. The flanges 3 effectively improve the plastic flow of the material, avoid cracking or wrinkling, and thus improve the stability. At the front and rear positions of the two side plates 2 near the upper and lower edge positions, two second reinforcing ribs 5 are axially symmetrically and fixedly arranged by stamping into the inside of the column. The two second reinforcing ribs 5 significantly improve the local strength of the two side plates 2 when bearing large loads or concentrated forces and effectively disperse the stress, and at the same time help to improve the overall rigidity and stability of the column.

[0035] A plurality of hanging holes 13 are sequentially provided through the front and rear ends of the two side plates 2 along the axis. A fifth mounting hole 12 is provided through the front and rear ends of the two side plates 2 near one side edge position. During use, the user can customize the hanging holes 13 of the hanging plate at different positions, and at the same time, other components of the compact shelf can be conveniently installed by the user through the fifth mounting hole 12 according to actual needs.

[0036] The internal strengthening structure 7 is fixedly arranged through the inside of the column. The internal strengthening structure 7 includes a circular tube 701, a plurality of first supports 702 and a plurality of second supports 703. The circular tube 701 is fixedly arranged along the axial direction of the column to the central position inside the column. The lower ends of the plurality of first supports 702 are fixedly arranged along the axial direction to the upper end of the main board 1 in sequence. The upper ends of the plurality of first supports 702 are fixedly arranged along the axial direction to the lower end of the circular tube 701 in sequence. The plurality of second supports 703 are respectively and alternately hung through the holes 13 to fixedly connect the inner surfaces of the two side plates 2 and the outer surface of the circular tube 701. The circular tube 701 is fixedly arranged to the central position inside the column to provide a firm central support. When the plurality of first supports 702 and second supports 703 are evenly dispersed, the load applied to the column is dispersed to avoid local stress concentration. In particular, by increasing the plurality of internal support points, the overall rigidity and bearing capacity of the column are significantly improved, and the column is effectively prevented from being twisted or bent when being impacted.

[0037] The circular tube 701 is made of engineering plastic material, and the plurality of first supports 702 and the plurality of second supports 703 are made of polyurethane material. The use of engineering plastic material for the circular tube 701 significantly reduces the weight of the column on the premise of ensuring the structural strength, improves the convenience of transportation and installation and use by the user, and at the same time reduces the load brought by the self-weight of the compact rack. The polyurethane material used for the plurality of first supports 702 and second supports 703 has excellent elasticity and buffering performance, and provides a good effect of absorbing impact and damping for the column.

[0038] Working principle: The column is formed by bending the same steel plate to form the main board 1 and two side plates 2. Two first reinforcing ribs 4 and pattern reinforcing ribs 6 are provided to improve the local strength and torsional resistance of the main board 1. Two second reinforcing ribs 5 are provided to improve the local strength of the side plates 2, and two flanges 3 are provided to further enhance the overall rigidity.
