Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel pipes, and specifically relates to a thin-walled stainless steel pipe. Background Art

[0002] A steel pipe with an outer diameter to wall thickness ratio greater than 20 is called a thin-walled steel pipe. Due to the thin pipe wall of the thin-walled steel pipe, the pipe orifice part is prone to deformation when subjected to external force. When the opening of the steel pipe is deformed, the connection tightness of the overall pipeline will be affected.

[0003] Chinese Patent with the publication number CN218935532U discloses a thin-walled stainless steel pipe, including a stainless steel pipe body. An anti-deformation mechanism is arranged inside the stainless steel pipe body. The anti-deformation mechanism includes a central ring. A number of telescopic rods are arranged on the outer ring of the central ring. An arc-shaped clamping bracket is arranged at the telescopic end of the telescopic rod. The arc-shaped clamping bracket is in contact with the inner wall of the stainless steel pipe body. A support frame is also arranged on the telescopic rod. By arranging the anti-deformation mechanism inside the stainless steel pipe body, the arc-shaped clamping bracket and the support frame resist external forces to prevent deformation at the opening and ensure the connection tightness of the overall pipeline.

[0004] The above-mentioned existing technical solutions have the following defects: The inner wall of the thin-walled stainless steel pipe is supported by multiple groups of support frames and multiple groups of arc-shaped clamping brackets. However, there are gaps between the arc-shaped clamping brackets, so it cannot fully support the inner wall of the thin-walled stainless steel pipe, thereby reducing the reliability of supporting and preventing deformation of the thin-walled stainless steel pipe. In view of the above situation, technical innovation is carried out on the basis of the existing thin-walled stainless steel pipe. Summary of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 - 3, a thin-walled stainless steel pipe, including a thin-walled stainless steel pipe 1. On both the front and rear sides of the inner side wall of the thin-walled stainless steel pipe 1, a set of support rings 16 are slidably arranged. On the outer side wall of the support ring 16, an anti-slip pad 161 is fixedly arranged. The anti-slip pad 161 is attached to the inner side wall of the thin-walled stainless steel pipe 1. Through the support ring 16, the inner wall of the opening of the thin-walled stainless steel pipe 1 is supported, thereby effectively preventing the opening of the thin-walled stainless steel pipe 1 from being deformed by external force extrusion. On both the left and right sides of the support ring 16, a set of jacks are opened. The jacks are located outside the thin-walled stainless steel pipe 1. Among them: On the opposite sides of the two support rings 16, a set of fixing components are placed. The fixing component includes a guide rail 15. Inside the guide rail 15, a bidirectional lead screw 17 is rotatably arranged. On the outer side wall of the bidirectional lead screw 17, two internal thread sliders 19 are evenly screwed. On the opposite sides of the two internal thread sliders 19, a set of pins 191 are fixedly arranged. A magnetic block 192 is embedded on the outer side of the internal thread slider 19. The support ring 16 is located between the two internal thread sliders 19. The pin 191 is inserted into the jack of the support ring 16. The outer side of the thin-walled stainless steel pipe 1 is attached to the side of the internal thread slider 19 away from the guide rail 15. The magnetic block 192 and the thin-walled stainless steel pipe 1 are magnetically attracted to each other. Through the magnetic attraction between the thin-walled stainless steel pipe 1 and the magnetic block 192 and the friction between the thin-walled stainless steel pipe 1 and the anti-slip pad 161, it can effectively ensure that the thin-walled stainless steel pipe 1 can be stably fixed on the outer sides of the support ring 16 and the internal thread slider 19, thereby improving the reliability of the support of the support ring 16 for the thin-walled stainless steel pipe 1. On the outer side of the guide rail 15, a support frame 11 is placed. On the top of the support frame 11, two guide grooves are evenly penetrated. On the right side of the support frame 11, an avoidance groove is penetrated. The bottom of the support frame 11 is flush with the bottom of the thin-walled stainless steel pipe 1. Through the support frame 11, the outer side of the thin-walled stainless steel pipe 1 can be supported, thereby improving the stability of the thin-walled stainless steel pipe 1 placed on a plane. On the top of the guide rail 15, two screws 12 are evenly fixedly arranged. On the outer side wall of the screw 12, a second nut 14 and a first nut 13 are screwed. The second nut 14 is located at the top of the inner side wall of the support frame 11. The first nut 13 is located on the top of the support frame 11. The right side of the bidirectional lead screw 17 penetrates the right side of the guide rail 15 and the avoidance groove of the support frame 11 and is connected with a hand wheel 18. By inserting the pin 191 into the jack of the support ring 16, the support ring 16 can be fixed between the two internal thread sliders 19. Rotating the hand wheel 18 drives the bidirectional lead screw 17 to rotate. Through the bidirectional lead screw 17, the two internal thread sliders 19 are driven to move outwards, thereby driving the pin 191 to separate from the jack of the support ring 16, and thus the support ring 16 can be removed. After loosening the first nut 13 and the second nut 14, the guide rail 15 can be moved up and down. When the position of the guide rail 15 is determined, tightening the first nut 13 and the second nut 14 can complete the height fixation of the guide rail 15. Through the height adjustability of the guide rail 15 and the detachable and replaceable nature of the support ring 16, different sizes of thin-walled stainless steel pipes 1 can be adapted by adjusting the height of the guide rail 15 and replacing support rings 16 of different sizes.Furthermore, the adaptability of the device is improved.

[0022] Working principle: Support is completed through the inner wall at the opening of the thin-walled stainless steel tube 1 of the support ring 16, which can effectively prevent the opening of the thin-walled stainless steel tube 1 from being deformed by external force extrusion. Through the magnetic attraction between the thin-walled stainless steel tube 1 and the magnet 192 and the friction force between the thin-walled stainless steel tube 1 and the anti-slip pad 161, it can effectively ensure that the thin-walled stainless steel tube 1 can be stably fixed on the outside of the support ring 16 and the internal thread slider 19, thereby improving the reliability of the support of the support ring 16 for the thin-walled stainless steel tube 1. The outside of the thin-walled stainless steel tube 1 can be supported by the support frame 11 to improve the stability of the thin-walled stainless steel tube 1 placed on a plane. By inserting the pin 191 into the jack of the support ring 16, the support ring 16 can be fixed between the two internal thread sliders 19. Rotate the handwheel 18 to drive the bidirectional lead screw 17 to rotate. Drive the two internal thread sliders 19 to move outwards through the bidirectional lead screw 17, thereby driving the pin 191 to separate from the jack of the support ring 16, and then the support ring 16 can be removed. After loosening the first nut 13 and the second nut 14, the guide rail 15 can be moved up and down. When the position of the guide rail 15 is determined, tightening the first nut 13 and the second nut 14 can complete the height fixation of the guide rail 15. Through the height adjustability of the guide rail 15 and the detachable replaceability of the support ring 16, the height of the guide rail 15 can be adjusted and different sizes of support rings 16 can be replaced to adapt to thin-walled stainless steel tubes 1 of different sizes, thereby improving the adaptability of the device.
