Office table leg with good deformation resistance

Abstract

This utility model relates to the field of office desks, and more particularly to an office desk leg with good anti-deformation performance. The leg is hexagonal, with a groove at the top. A reinforcing rib is fixedly connected to the bottom of the groove, and multiple reinforcing rings are fixedly installed on the outside of the reinforcing rib. The outer side of the reinforcing rings contacts the inner side of the groove. One side of the leg is connected to a wedge-shaped groove on one side of a support plate via a wedge block. The support plate is fixedly positioned between the front and rear legs. A tabletop is connected to the top of the leg. The leg employs a three-layer composite structure consisting of the leg body, a reinforcing layer, and a wear-resistant layer. The groove at the top of the leg, which connects the reinforcing rib and reinforcing rings, effectively prevents deformation when subjected to external impact or large loads. The support plate and multiple connecting plates disperse stress when the leg connects to the tabletop, preventing stress concentration that could cause the leg to tilt and deform.

Description

Technical Field

[0001] This utility model relates to the field of office desk technology, and in particular to an office desk leg with good resistance to deformation. Background Technology

[0002] As a core piece of furniture in daily office work, the stability of the desk directly affects the user experience. The desk legs, as key components supporting the desktop, are mainly used to support office supplies on the desktop, providing users with a stable working platform.

[0003] Most existing office desks have hollow columnar legs with a lack of internal reinforcement, resulting in weak torsional and compressive strength. They are prone to bending and deformation when subjected to external impacts or long-term heavy loads. The connection between the legs and the desktop is usually only secured with simple bolts, which concentrates stress at the connection points and can lead to loosening after long-term use, causing the legs to tilt or even deform. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a desk leg with good resistance to deformation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A desk leg with good deformation resistance includes a hexagonal table leg with a groove at the top. A reinforcing rib is fixedly connected to the bottom of the groove. Multiple reinforcing rings are fixedly installed on the outside of the reinforcing rib. The outside of the reinforcing rings contacts the inside of the groove. One side of the table leg is connected to the wedge groove on the side of the support plate through a wedge block. The support plate is fixedly positioned between the front and rear table legs.

[0007] The table legs are connected to the top of the table board. The bottom of the table board is fixedly installed with the front and back sides of the table board. Limiting blocks are fixedly installed in the middle of the left and right sides of the first connecting plate. The bottom of the table board is fixedly installed with the front and back sides of the table board. The second connecting plate is located between the two first connecting plates. The upper and lower ends of the left and right sides of the second connecting plate are fixedly installed with locking blocks.

[0008] In addition, a preferred structure is that a limiting groove is provided on one side of the table leg, and the limiting groove corresponds to the position of the limiting block on one side of the first connecting plate.

[0009] In addition, a preferred structure is that the outer side of the table legs is provided with a reinforcing layer, and a wear-resistant layer is fixedly installed on the outer side of the reinforcing layer.

[0010] In addition, a preferred structure is that a rubber sleeve is fixedly installed at the bottom of the table legs, and the bottom of the rubber sleeve is provided with anti-slip texture.

[0011] In addition, a preferred structure is that the bottom end of the first connecting plate is fixedly connected to the horizontal part of the L-shaped reinforcing plate, and the vertical part of the L-shaped reinforcing plate is fixedly connected to the inner side of the table leg.

[0012] In addition, a preferred structure is that the left and right sides of the inner side of the support plate are provided with slots, and the inner side of the slots contacts the outer side of the block.

[0013] In addition, the preferred structure is that the reinforcing layer is made of glass fiber reinforced plastic and the wear-resistant layer is made of wear-resistant ABS.

[0014] The beneficial effects of this utility model are as follows: by setting the table legs, which adopt a three-layer composite structure consisting of the table leg body, the reinforcing layer and the wear-resistant layer, and the reinforcing rib and the reinforcing ring are fixedly connected at the top of the table legs through the groove, the table legs can effectively prevent deformation when subjected to external impact or large load; by setting the support plate and multiple connecting plates, the table legs can disperse stress when connected to the table board, avoiding the table legs tilting and deforming due to stress concentration.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6 A desk leg with good deformation resistance includes a leg 1, a tabletop 2, and a support plate 3. The leg 1 is a three-layer composite structure composed of the leg body, a reinforcing layer 11, and a wear-resistant layer 12. A groove 13 is provided at the top of the leg 1. A reinforcing rib 16 is fixedly connected to the bottom of the groove 13. The bottom of the reinforcing rib 16 contacts the bottom of the groove 13. Multiple reinforcing rings 17 are fixedly installed on the outside of the reinforcing rib 16. The reinforcing rings 17 are vertically distributed in the groove 13. The outside of the reinforcing rings 17 contacts the inside of the groove 13. One side of the leg 1 is connected to the wedge groove 31 on one side of the support plate 3 through a wedge block 15. The support plate 3 is fixed between the front and rear legs 1. In addition, the reinforcing layer 11 is made of glass fiber reinforced plastic, and the wear-resistant layer 12 is made of wear-resistant ABS.

[0024] The top of the table leg 1 is connected to the table board 2. The bottom of the table board 2 is fixedly installed with the front and rear sides of the bottom. The left and right sides of the first connecting plate 21 are fixedly installed with the limiting block 22. The bottom of the table board 2 is fixedly installed with the front and rear sides of the bottom. The second connecting plate 23 is located between the two first connecting plates 21. The left and right sides of the second connecting plate 23 are fixedly installed with the upper and lower ends of the upper and lower ends of the upper and lower ends. In addition, the bottom of the first connecting plate 21 is fixedly installed with the L-shaped reinforcing plate 25. The horizontal part of the L-shaped reinforcing plate 25 is fixed to the bottom of the first connecting plate 21 by bolts. The vertical part of the L-shaped reinforcing plate 25 is fixed to the inner side of the table leg 1 by bolts.

[0025] A limiting groove 14 is provided on one side of the table leg 1. The limiting groove 14 corresponds to the limiting block 22 on one side of the first connecting plate 21. The inner side of the limiting groove 14 contacts the outer side of the limiting block 22. A rubber sleeve 18 is fixedly installed at the bottom of the table leg 1. The rubber sleeve 18 is located on the outer side of the table leg 1. The bottom of the rubber sleeve 18 is provided with anti-slip texture 19. In addition, slots 32 are opened on the left and right sides of the inner side of the support plate 3. The inner side of the slots 32 contacts the outer side of the locking block 24.

[0026] In this embodiment, during installation, the two table legs 1 on the front and back sides are removed, and then a support plate 3 is removed. The wedge-shaped groove 31 on one side of the support plate 3 is aligned with the wedge-shaped block 15 on one side of one table leg 1 and inserted. Then, the other table leg 1 is inserted by aligning the wedge-shaped block 15 on one side with the wedge-shaped groove 31 on the other side of the support plate 3. In this way, the support plate 3 will be initially fixed and limited to the inside of the two table legs 1. At this time, the other support plate 3 and the two table legs 1 are removed, and the support plate 3 is limited between the two table legs 1 in the same way. Then, the tabletop 2 is removed and placed vertically in one place. First, the table legs 1 on one side and the support plate 3 are assembled. First, the limiting groove 14 on one side of the two table legs 1 is aligned with the first wedge-shaped groove 15 on the front and back sides of the bottom of the tabletop 2. Insert the limiting block 22 on one side of the connecting plate 21, then align the slots 32 on the left and right sides of the inner side of the support plate 3 with the slots 24 on one side of the second connecting plate 23 on the front and rear sides of the bottom of the tabletop 2, and insert them. Once the limiting block 22 and slot 24 are all inserted into the limiting groove 14 and slot 32, the process is complete. Then, install the table leg 1 and support plate 3 on the other side of the tabletop 2 in the same way. Then, fix the horizontal part of the L-shaped reinforcing plate 25 to the bottom of the first connecting plate 21 with bolts, and fix the vertical part of the L-shaped reinforcing plate 25 to one side of the table leg 1 with bolts. After all the reinforcing plates 25 are fixed, the table leg 1, support plate 3 and tabletop 2 will be mutually limited and fixed together, and then the desk can be placed in one place for use.

[0027] When in use, office supplies are piled on top of the desk tabletop 2. Due to the three-layer composite structure of the table leg 1, the reinforcing layer 11, and the wear-resistant layer 12, the office supplies on top of the desk tabletop 2 can bear a large load. The weight of the numerous office supplies is evenly transferred from the desk tabletop 2 to the table leg 1 through the first connecting plate 21, the second connecting plate 23, and the support plate 3, and then from the table leg 1 to the ground. The table leg 1 will not tilt or deform due to stress concentration at the connection. However, in humid environments, the outer side of the table leg 1 is made of wear-resistant ABS, which will not cause corrosion of the table leg 1 due to long-term exposure to humid environments, preventing the table leg 1 from bending and deforming due to the large load. In addition, the bottom of the table leg 1 is equipped with a rubber sleeve 18 with anti-slip texture 19, which can increase the friction between the table leg 1 and the ground in humid environments and prevent the desk from sliding.

[0028] However, when the table leg 1 is subjected to an external impact, because the outer side of the table leg 1 is reinforced with a reinforcing layer 11, which is made of glass fiber reinforced plastic, glass fiber reinforced plastic is composed of reinforcing fibers and a matrix, and has the characteristics of being lightweight, high-strength, and having a low modulus of elasticity, and because the top of the table leg 1 is fixedly connected to a cross reinforcing rib 16 and a reinforcing ring 17 through a groove 13, the cross reinforcing rib 16 and the reinforcing ring 17 form a mesh-like internal support, which can prevent the table leg 1 from bending and deforming when subjected to a large impact.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
