AI Technical Summary
When riveting existing square tubes, the riveting structure tends to protrude from the tube body, resulting in unstable connections, and the countersunk hole structure is not strong enough.
The structure employs a combination of countersunk rivet nuts and reinforcing blocks. The rivet nuts are inserted into the reinforcing blocks, and reinforcing blocks are also installed on the inner wall of the square tube to enhance the connection strength. Combined with ribs, the structure's stability is enhanced.
This approach improves the stability and strength of the connection while avoiding gaps at the connection ends, ensuring the stress stability and ease of installation of the square tube.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical engineering technology, specifically to a square tube structure. Background Technology
[0002] Square tubing is a hollow metal profile with a square or rectangular cross-section, typically made from steel, aluminum alloy, copper, stainless steel, or other metal materials through rolling, extrusion, and welding processes. Its core feature is its hollow structure, which retains the high strength of the metal material while reducing its weight. Furthermore, the square or rectangular cross-section design gives it superior stress stability and ease of installation compared to round tubing. It can be used in mechanical equipment to form the required frame structure. However, current methods of connecting and fixing square tubing to other components using riveting result in the riveting structure protruding from the tubing, creating gaps in the connection. If a countersunk hole structure is used, the riveting structure penetrates a large amount into the tubing, easily leading to unstable connections and other shortcomings. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a square tube structure, including a square tube body, the square tube body including a first tube and a second tube connected vertically, and a connecting component, the connecting component being respectively disposed on the first tube and the second tube, the connecting component including a rivet nut and a reinforcing block, the first tube and the second tube being provided with countersunk holes, the rivet nut being disposed in the countersunk holes, the reinforcing block being disposed on the inner wall of the first tube and the second tube, and the rivet nut being inserted into the reinforcing block.
[0005] Furthermore, the outer end face of the rivet nut is flush with the outer end face of the square tube body.
[0006] Furthermore, at least two rivet nuts are provided on the first pipe body, one of the reinforcing blocks is attached to the inner wall of the first pipe body, and multiple rivet nuts pass through the reinforcing block.
[0007] Furthermore, at least two rivet nuts are provided on the first pipe body, and at least two reinforcing blocks are attached to the inner wall of the first pipe body. Each rivet nut passes through a reinforcing block, and there is a gap between two adjacent reinforcing blocks.
[0008] Furthermore, it also includes multiple ribs, which are disposed on the inner side of the corner of the square tube body and on the first tube body, and the countersunk hole penetrates through the ribs.
[0009] This utility model has the following beneficial effects:
[0010] The structure of this utility model, which combines a countersunk rivet nut with a reinforcing block, ensures the required connection strength while avoiding gaps at the connection end faces and preventing skewing. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Example 1
[0019] like Figures 1-3 As shown, the square tube structure provided in this embodiment includes a square tube body and a connecting component. The square tube body includes a first tube 10 and a second tube 20 connected vertically. The second tube 20 is shorter than the first tube 10, forming an L-shaped square tube structure. The connecting component is correspondingly disposed on the first tube 10 and the second tube 20. A corresponding number of countersunk holes are opened at corresponding positions on the first tube 10 and the second tube 20 to accommodate the connecting component.
[0020] Specifically, the connecting assembly includes a rivet nut 30 and a reinforcing block 40. The rivet nut 30 is disposed in a countersunk hole, so that the outer end face of the rivet nut 30 is flush with the outer end face of the square tube body. The reinforcing block 40 is disposed on the inner wall of the first tube body 10 and the second tube body 20, corresponding to the position of the countersunk hole. The rivet nut 30 is inserted into the reinforcing block 40, and the tail of the rivet nut 30 protrudes from the reinforcing block 40.
[0021] Here, two rivet nuts 30 are provided on the first tube body 10, and a reinforcing block 40 is attached to the inner wall of the first tube body 10, covering the two corresponding countersunk holes. Both rivet nuts 30 pass through the reinforcing block 40. On the second tube body 20, a countersunk hole, a rivet nut 30, and a reinforcing block 40 are provided.
[0022] Here, the connecting component on the first tube 10 is located at the end of the first tube 10 away from the second tube 20.
[0023] Example 2
[0024] like Figure 4 As shown, in this embodiment, two rivet nuts 30 are provided on the first tube body 10, and two reinforcing blocks 40 are attached to the inner wall of the first tube body 10, respectively covering the two corresponding countersunk holes. There is a gap between the two adjacent reinforcing blocks 40, and the two rivet nuts 30 pass through one reinforcing block 40 respectively.
[0025] Example 3
[0026] like Figure 5 As shown, in this embodiment, a rib plate 50 is welded to the outside of the square tube body. The two rib plates 50 are respectively located on the inner side of the corner of the square tube body and near the end of the first tube body 10. The rib plate 50 at the corner is L-shaped, and the rib plate 50 on the first tube body 10 is straight. The countersunk hole passes through the rib plate 50, and the end of the rivet nut 30 is located at the position of the rib plate 50 and is flush with the end face of the rib plate 50.
[0027] Of course, a connecting component can be added to the end of the first tube 10 near the second tube 20 to improve the connection effect.
[0028] It should be noted that the reinforcing block 40 is welded to the square tube body, and is fixed to the plate before the square tube body is welded into shape.
