Description

Technical Field

[0001] This utility model relates to the field of square tube processing technology, and in particular to a welded reinforcement structure for a waist-shaped sleeve. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many energy sources for modern welding, including gas flame, electric arc, laser, electron beam, friction and ultrasound. Welding is required when processing square tubes. Square tubes are a type of square and rectangular tube, that is, steel pipes with equal or unequal side lengths. They are made by rolling strip steel through a process. Generally, the strip steel is unpacked, flattened, rolled, and welded to form a round tube, which is then rolled into a square tube and cut to the required length.

[0003] The existing structure for reinforcing the waist-shaped sleeve is difficult to improve the welding strength. The existing structure is to add a sleeve at the mounting hole on the square tube to solve the problem of the hole being sunken due to bolt tightening, which eventually leads to the loosening of the bolt and the resulting decrease in the overall vehicle performance. The square tube is laser-cut and the hole is cut, so the sleeve is welded to the square tube to prevent the tube body from sunken and deformed when the bolt is tightened. At the same time, it can also strengthen the square tube to prevent the strength reduction caused by the hole cutting. However, this solution requires the surface to be ground flat after welding, which leads to insufficient welding strength and easy detachment, ultimately affecting the use of the whole vehicle. Utility Model Content

[0004] The purpose of this invention is to provide a weld reinforcement structure for a waist-shaped sleeve, in order to solve the defect that the existing weld reinforcement structure for waist-shaped sleeves is difficult to strengthen the weld strength.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a welded reinforcement structure for a waist-shaped sleeve, comprising a square tube; the outer side of the square tube is coated with an anti-corrosion coating, and a reinforcement structure is installed inside the square tube; openings are provided on both sides of the square tube, an outer edge is installed on both sides of the square tube, a cavity is provided inside the square tube, and a welded structure is installed at the top of the square tube.

[0006] The welding structure includes a sleeve, a through hole, and a weld. The sleeve is installed at the top of the square tube, and the through hole is provided inside the sleeve.

[0007] When using it, the sleeve needs to be ground flat after welding. If the welding strength is insufficient, the sleeve is easy to fall off. After grinding flat, the welding contact surface is only a thin layer. The through hole is wrapped by the sleeve. Four semi-circular holes are opened on the side of the through hole of the square tube as welds. By adding welds on the square tube, the welding contact surface is increased and the welding strength is improved.

[0008] Furthermore, the square tube has an internal wear-resistant structure, which includes a wear-resistant plate, wear-resistant texture, and a connecting layer. The connecting layer is located inside the square tube, and a wear-resistant plate is installed on the inner side of the connecting layer. The wear-resistant plate can protect the inner wall of the square tube.

[0009] Furthermore, the wear-resistant plate has wear-resistant patterns on its outer side, which are arranged at equal intervals on the outer side of the wear-resistant plate. The wear-resistant patterns can enhance the wear resistance of the wear-resistant plate.

[0010] Furthermore, the reinforcing structure includes a reinforcing plate, a mounting plate, and mounting screws. The reinforcing plate is installed on the inner side of the square tube, and mounting plates are installed on both sides of the reinforcing plate. A mounting screw passes through the middle of the mounting plate. The reinforcing plate can enhance the structural strength of the square tube.

[0011] Furthermore, the outer sidewall of the mounting screw is uniformly provided with external threads, and the inner sidewall of the mounting plate is uniformly provided with internal threads that cooperate with the external threads. The mounting screw and the mounting plate are threadedly connected, and the protective plate can be fixed by the cooperation of the mounting screw and the mounting plate.

[0012] Furthermore, welds are installed on both sides and both ends of the sleeve, and the welds are symmetrically distributed about the central axis of the sleeve. By adding welds to the square tube, the welding contact surface is increased, and the welding strength is improved.

[0013] The advantages of the welded reinforcement structure of the waist-shaped sleeve provided by this utility model are: by adding welds to the square tube, the welding contact surface is increased, the welding strength is improved, and through this process optimization and adjustment, the consistency and stability of the product are greatly improved.

[0014] By setting a through hole at the top of the square tube, the sleeve needs to be ground flat after welding, which leads to insufficient welding strength and easy detachment of the sleeve. After grinding flat, the welding contact surface is only a thin layer. The through hole is wrapped by the sleeve. Four semi-circular holes are opened on the side of the through hole of the square tube as welds. By adding welds on the square tube, the welding contact surface is increased and the welding strength is improved. This achieves the purpose of strengthening the welding strength of the waist-shaped sleeve welding reinforcement structure.

[0015] By installing a reinforcing plate inside the square tube, which can be made of steel, the reinforcing plate is installed inside the square tube by a mounting plate and mounting screws, forming a threaded connection. Since the reinforcing plate protects the four sides of the square tube, it can prevent the square tube from deforming. This achieves the purpose of strengthening the structural strength of the square tube by welding the waist-shaped sleeve. Attached Figure Description

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.

[0023] Please see Figures 1-5 One embodiment of this utility model is a welded reinforcement structure for a waist-shaped sleeve, comprising a square tube 1.

[0024] The outer side of the square tube 1 is coated with an anti-corrosion coating 2. The inside of the square tube 1 is provided with a wear-resistant structure 4, which includes a wear-resistant plate 401, wear-resistant texture 402 and a connecting layer 403.

The wear-resistant texture 402 is provided on the outer side of the wear-resistant plate 401. The wear-resistant texture 402 is arranged at equal intervals on the outer side of the wear-resistant plate 401.

[0025] See attached document Figure 2-3 As shown, the outer side of the square tube 1 is coated with anti-corrosion paint, which can enhance the corrosion resistance of the square tube 1. The inside of the square tube 1 is connected by a connecting layer 403 and a wear-resistant plate 401. The wear-resistant plate 401 is provided with wear-resistant texture 402. The wear-resistant plate 401 and the wear-resistant texture 402 can enhance the wear resistance of the inner side of the square tube 1 and prevent wear from occurring on the inner side of the square tube 1.

[0026] The square tube 1 has a reinforcing structure 3 installed inside. The reinforcing structure 3 includes a reinforcing plate 301, a mounting plate 302, and a mounting screw 303. The reinforcing plate 301 is installed on the inner side of the square tube 1. Mounting plates 302 are installed on both sides of the reinforcing plate 301. A mounting screw 303 passes through the middle of the mounting plate 302. External threads are evenly provided on the outer side wall of the mounting screw 303. Internal threads that cooperate with the external threads are evenly provided on the inner side wall of the mounting plate 302. The mounting screw 303 and the mounting plate 302 are connected by threads.

[0027] See attached document Figure 2 and attached Figure 4 As shown, the reinforcing plate 301 can be made of steel. The reinforcing plate 301 is installed inside the square tube 1 by the mounting plate 302 and the mounting screws 303. The mounting plate 302 and the mounting screws 303 form a threaded connection. Since the reinforcing plate 301 protects the four sides of the square tube 1, the reinforcing plate 301 can prevent the square tube 1 from deforming.

[0028] The square tube 1 has openings 7 on both sides, outer edges 6 on both sides, a cavity 5 inside, and a welded structure 8 at the top.

[0029] The welded structure 8 includes a sleeve 801, a through hole 802, and a weld 803. The sleeve 801 is installed at the top of the square tube 1. The sleeve 801 has a through hole 802 inside. Welds 803 are installed on both sides and both ends of the sleeve 801, and the welds 803 are symmetrically distributed about the central axis of the sleeve 801.

[0030] See attached document Figure 1 and attached Figure 5 As shown, the sleeve 801 needs to be ground flat after welding, which results in insufficient welding strength and the sleeve 801 is easy to fall off. After grinding flat, the welding contact surface is only a thin layer. The through hole 802 is wrapped by the sleeve 801. Four semi-circular holes are opened on the side of the through hole 802 of the square tube 1 as weld seams 803. By adding weld seams 803 on the square tube 1, the welding contact surface is increased and the welding strength is improved.
