Technical Field

[0001] This utility model relates to the field of pipe technology, specifically to a torsion-resistant stainless steel pipe reinforcement device. Background Technology

[0002] Stainless steel pipe is a long, round steel material with a hollow cross-section. It has excellent mechanical properties and corrosion resistance, and is widely used in various industrial fields such as petroleum, chemical, medical, food, light industry, and machinery. It serves as a pipeline for transporting fluids and a key component in mechanical structures. However, existing stainless steel pipes have poor resistance to torsion and bending, and are prone to bending in localized areas. This increases the wear on the outer wall of the stainless steel pipe and makes maintenance more difficult. Utility Model Content

Connecting and reinforcing components for connecting the stainless steel pipe body and the arc-shaped outer shells are symmetrically connected on the inner sides of the four arc-shaped outer shells. Torsion-resistant connecting components for torsion resistance are provided between the four arc-shaped outer shells. The connecting reinforcement includes two arc-shaped connecting plates symmetrically arranged inside the stainless steel tube. Threaded sleeves pass through both sides of the stainless steel tube, and drive screws are installed inside the two threaded sleeves. One end of each drive screw is rotatably connected to the outer wall of the two arc-shaped connecting plates.

[0005] As a preferred embodiment of this utility model, the outer walls of the two drive screws are respectively threaded to the inner walls of the two threaded sleeves, and a knob is fixedly connected to the end of each of the two drive screws away from the arc-shaped connecting plate. Anti-slip ridges are evenly distributed on the side walls of the two knobs.

[0006] By using the above technical solution, two arc-shaped outer shells are connected to the outside of the stainless steel tube using fastening bolts. By pressing the drive screw and arc-shaped connecting plate against the outside of the stainless steel tube, the bending resistance of the stainless steel tube can be enhanced, effectively preventing bending in localized areas, thereby reducing wear on the outer wall of the stainless steel tube and reducing the difficulty of maintaining the stainless steel tube.

[0007] As a preferred embodiment of this utility model, guide rods are provided on both sides of the two drive screws, one end of the four guide rods is fixedly connected to the surface of the two arc-shaped connecting plates, and the other end of the four guide rods penetrates the top of the stainless steel tube.

The outer walls of the two adjusting screws are threadedly connected to the inner wall of the adjusting sleeve, and a rotating disk is fixedly connected to the outer wall of the adjusting sleeve.

[0011] Through the above technical solutions, the adjusting screw, adjusting sleeve, anti-torsion guide rod and anti-torsion sleeve can enhance the torsional resistance of the stainless steel pipe body. When the stainless steel pipe body is subjected to torsional force, it can effectively disperse and resist the torsional force.

[0012] As a preferred embodiment of this utility model, anti-torsion guide rods are fixedly connected to the sides of the two second connecting blocks that are close to each other, and an anti-torsion sleeve is provided between the two second connecting blocks. The ends of the two anti-torsion guide rods that are close to each other extend into the interior of the anti-torsion sleeve.

[0020] For examples, please refer to Figure 1-4 This utility model provides a technical solution: A torsion-resistant stainless steel pipe reinforcement device includes a stainless steel pipe body 1.

Connecting and reinforcing parts 3 for connecting the stainless steel pipe body 1 and the arc-shaped outer shells 2 are symmetrically connected on the inner sides of the four arc-shaped outer shells 2. Torsion-resistant connecting parts 4 for anti-torsion are provided between the four arc-shaped outer shells 2. The connecting reinforcement 3 includes two arc-shaped connecting plates 301 symmetrically arranged inside the stainless steel tube body 1. Threaded sleeves 302 pass through both sides of the stainless steel tube body 1. Drive screws 303 are installed inside the two threaded sleeves 302. One end of the two drive screws 303 is rotatably connected to the outer wall of the two arc-shaped connecting plates 301 respectively. The outer walls of the two drive screws 303 are threadedly connected to the inner walls of the two threaded sleeves 302 respectively. A knob 304 is fixedly connected to the end of the two drive screws 303 away from the arc-shaped connecting plate 301. Anti-slip ridges are evenly distributed on the side walls of the two knobs 304. Guide rods 305 are provided on both sides of the two drive screws 303. One end of the four guide rods 305 is fixedly connected to the surface of the two arc-shaped connecting plates 301 respectively. The other end of the four guide rods 305 passes through the top of the stainless steel tube 1. The four stainless steel pipes 1 are arranged in pairs, and the connecting and reinforcing parts 3 on the inner side of the two sets of stainless steel pipes 1 are the same. The two sets of stainless steel pipes 1 are connected by fastening bolts. The anti-torsion connector 4 includes a first connecting block 401 fixedly connected to the middle of the outer wall of the stainless steel tube 1, and second connecting blocks 402 symmetrically connected to both sides of the outer wall of the stainless steel tube 1. An adjusting screw 403 is rotatably connected to the side of the two first connecting blocks 401 that is close to each other. An adjusting sleeve 404 is provided between the two first connecting blocks 401. The ends of the two adjusting screws 403 that are away from the first connecting blocks 401 extend into the interior of the adjusting sleeve 404. The outer walls of the two adjusting screws 403 are threadedly connected to the inner wall of the adjusting sleeve 404. A rotating disk 405 is fixedly connected to the outer wall of the adjusting sleeve 404. Two anti-torsion guide rods 406 are fixedly connected to each other on one side of the two second connecting blocks 402. An anti-torsion sleeve 407 is provided between the two second connecting blocks 402. The ends of the two anti-torsion guide rods 406 that are close to each other extend into the interior of the anti-torsion sleeve 407. Limiting plates 408 are fixedly connected to the ends of the two anti-torsion guide rods 406 that are close to each other. The sidewalls of the two limiting plates 408 are slidably connected to the inner wall of the anti-torsion sleeve 407. The structures of the two sets of anti-torsion connecting parts 4 are arranged axially symmetrically.

[0021] Four arc-shaped outer shells 2 are fitted over the two ends of the stainless steel tube 1 and connected with fastening bolts. Then, the drive screw 303 is rotated by the knob 304. Since the drive screw 303 is threadedly connected to the threaded sleeve 302 and one end is rotatably connected to the arc-shaped connecting plate 301, under the guidance of the guide rod 305, the drive screw 303 rotates and drives the arc-shaped connecting plate 301 to move towards the stainless steel tube 1 until it is pressed tightly against its outside, thereby enhancing the bending resistance of the stainless steel tube 1. Furthermore, by rotating the adjusting sleeve 404 by rotating the rotating disk 405, since the adjusting screw 403 is threadedly connected to the adjusting sleeve 404, the rotation of the adjusting sleeve 404 will cause the two adjusting screws 403 to move closer or further apart, thereby adjusting the distance between the two sets of arc-shaped outer shells 2. In this embodiment, the adjusting screw 403, adjusting sleeve 404, anti-torsion guide rod 406, and anti-torsion sleeve 407 can effectively disperse and resist torsional force, preventing the stainless steel tube 1 from being damaged by torsion.

[0022] The working process of this utility model is as follows: In use, four arc-shaped outer shells 2 are fitted onto the outside of both ends of the stainless steel tube 1 and connected by fastening bolts. Then, the drive screw 303 is rotated by the knob 304. Since the drive screw 303 is threadedly connected to the threaded sleeve 302, and one end of the drive screw 303 is rotatably connected to the arc-shaped connecting plate 301, under the guidance of the guide rod 305, the rotation of the drive screw 303 will cause the arc-shaped connecting plate 301 to move towards the stainless steel tube 1 until the arc-shaped connecting plate 301 is tightly pressed against the outside of the stainless steel tube 1, thereby enhancing the bending resistance of the stainless steel tube 1. When it is necessary to adjust the torsional resistance of the stainless steel tube 1... During operation, the adjusting sleeve 404 can be rotated via the rotating disk 405. Since the adjusting screw 403 is threadedly connected to the adjusting sleeve 404, rotating the adjusting sleeve 404 will cause the two adjusting screws 403 to move closer or further apart, thereby adjusting the distance between the two sets of arc-shaped outer shells 2. At the same time, the anti-torsion guide rod 406 slides inside the anti-torsion sleeve 407, and the limiting plate 408 prevents the anti-torsion guide rod 406 from coming out of the anti-torsion sleeve 407. With this structural arrangement, when the stainless steel tube 1 is subjected to torsional force, the adjusting screw 403, adjusting sleeve 404, anti-torsion guide rod 406, and anti-torsion sleeve 407 can effectively disperse and resist the torsional force, preventing the stainless steel tube 1 from being damaged due to torsion.

[0023] If it is necessary to reinforce stainless steel pipes of different lengths, simply adjust the distance between the two sets of arc-shaped outer shells 2 by using the drive screw 303 and knob 304 to adapt them to stainless steel pipes of different lengths, and then complete the reinforcement installation by following the above operation steps.
