Description

Technical Field

[0001] This utility model relates to the field of stainless steel seamless pipe technology, specifically to a high-strength, impact-resistant stainless steel seamless pipe. Background Technology

[0002] Stainless steel seamless pipe is a long strip of steel with a hollow cross-section and no seams around its perimeter. It is made by piercing a whole round steel billet, and no welds or seams can be found on the entire cross-section of the pipe.

[0003] A search revealed Chinese patent CN218326698U, which discloses a novel seamless stainless steel pipe, comprising an outer pipe body, an inner pipe body fixedly connected to the inner wall of the outer pipe body, and two fixing discs fixedly connected to the outer surface of the outer pipe body. Each fixing disc has two sets of mounting holes on its right side. A first fixing ring and a second fixing ring are fixedly connected to the inner walls of the two fixing discs, respectively. A groove is formed on the right side of the second fixing ring, and a rubber ring is fixedly connected to the inner wall of the groove. The pipe is connected via the first fixing disc and the mounting holes. The first and second fixing rings guide the transported medium, and the rubber ring helps to shield the connection point, reducing leakage. Furthermore, the groove and the rubber ring enhance the sealing between the two fixing discs, thus solving the problem of difficulty in sealing the connection point, which easily leads to leakage during connection.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. Its tube structure is still a traditional single-layer or double-layer cylindrical structure, which lacks an effective buffer energy absorption mechanism. When subjected to external impact, the impact energy cannot be effectively absorbed or transferred, and there is still a risk that the tube may be dented or damaged due to local stress concentration. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a high-strength, impact-resistant stainless steel seamless pipe.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: An embodiment of this utility model provides a high-strength, impact-resistant stainless steel seamless pipe, including a stainless steel seamless pipe body and a pipe reinforcement mechanism; A steel pipe reinforcement mechanism is installed on the stainless steel seamless pipe body. The steel pipe reinforcement mechanism includes multiple reinforcing steel bars fixedly installed on the inner wall of the stainless steel seamless pipe body. A rotating assembly is installed on the stainless steel seamless pipe body. Two high-strength sleeve shells are rotatably connected to the stainless steel seamless pipe body on the rotating assembly. An elastic support assembly is jointly installed on the two high-strength sleeve shells. Multiple impact-resistant plates are installed on the elastic support assembly.

[0007] Furthermore, the rotating assembly includes a fixed ring fixedly mounted on a stainless steel seamless steel pipe body, and a movable ring shell fixed to a high-strength sleeve shell is rotatably mounted on the fixed ring.

[0008] Furthermore, the elastic support assembly includes multiple limiting shells that fit onto the movable ring shell and the high-strength sleeve shell, and each limiting shell has two mounting bolts threadedly installed at both ends, which are threadedly connected to the high-strength sleeve shell.

[0009] Furthermore, the inner wall of the limiting shell is connected to multiple springs, and the ends of the multiple springs are connected to a telescopic strip that is slidably connected to the limiting shell. The telescopic strip is fixed to the impact-resistant plate.

[0010] Furthermore, two rubber pads are symmetrically attached to the impact-resistant plate.

[0011] Furthermore, the two ends of the impact-resistant plate are provided with round holes that are adapted to the size of the mounting bolts.

[0012] Furthermore, a stretch film is wrapped around multiple of the aforementioned impact-resistant plates.

[0013] The above-described solution of this utility model has at least the following beneficial effects: 1. In this utility model, the strength of the stainless steel seamless steel pipe body can be improved by setting the reinforcing steel strip and the high-strength sleeve shell. The spring uses its own elasticity to support the impact plate through the telescopic strip. When the impact plate is subjected to external impact, the spring elasticity can offset the impact force, and the rubber pad can use its own flexibility to buffer and protect the impact plate, so that the stainless steel seamless steel pipe body has high impact resistance and strength.

[0014] 2. In this utility model, by setting a fixed ring and a movable ring shell structure, the impact-resistant plate has a rotation function. When subjected to external impact force, the impact-resistant plate drives the movable ring shell to rotate along the fixed ring through the telescopic strip, the limiting shell, the mounting bolt, and the high-strength sleeve shell, thereby allowing the impact-resistant plate to dissipate part of the impact force. The fixed ring and movable ring shell structure makes it easy to rotate the impact-resistant plate that needs to be replaced and maintained to a suitable disassembly angle. The mounting bolt is unscrewed from the inside of the high-strength sleeve shell through the round hole, and the limiting shell is disassembled, thus facilitating the disassembly of the impact-resistant plate.

[0017] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0018] like Figures 1 to 5 As shown, an embodiment of this utility model provides a high-strength, impact-resistant stainless steel seamless pipe, including a stainless steel seamless pipe body 1 and a steel pipe reinforcing mechanism. The steel pipe reinforcing mechanism is disposed on the stainless steel seamless pipe body 1 and includes multiple reinforcing steel bars 2 fixedly installed on the inner wall of the stainless steel seamless pipe body 1. A rotating assembly is disposed on the stainless steel seamless pipe body 1, and two high-strength sleeve shells 5 are disposed on the rotating assembly and rotatably connected to the stainless steel seamless pipe body 1. An elastic support assembly is disposed on both high-strength sleeve shells 5, and multiple impact-resistant plates 9 are disposed on the elastic support assembly. By setting up reinforcing steel bars 2 and high-strength sleeve shells 5, the strength of the stainless steel seamless pipe body 1 can be improved. Spring 7 uses its own elasticity to support the impact plate 9 through telescopic strip 8. When the impact plate 9 is subjected to external impact, the elasticity of spring 7 can offset the impact force, and rubber pad strip 10 can use its own flexibility to buffer and protect the impact plate 9, thereby giving the stainless steel seamless pipe body 1 high impact resistance and strength characteristics.

[0019] Figures 1 to 5As shown, the rotating assembly includes a fixed ring 3 fixedly installed on a stainless steel seamless steel pipe body 1. A movable ring shell 4 fixed to a high-strength sleeve shell 5 is rotatably installed on the fixed ring 3. The elastic support assembly includes multiple limiting shells 6 that fit into the movable ring shell 4 and the high-strength sleeve shell 5. Two mounting bolts 12 that are threaded to the high-strength sleeve shell 5 are threaded at both ends of each limiting shell 6. Multiple springs 7 are connected to the inner wall of the limiting shell 6. The ends of the multiple springs 7 are connected to a telescopic strip 8 that is slidably connected to the limiting shell 6. The telescopic strip 8 is fixed to an impact-resistant plate 9. Two rubber pads 10 are symmetrically pasted on the impact-resistant plate 9. The two ends of the impact-resistant plate 9 are provided with round holes 11 that are adapted to the size of the mounting bolts 12. A stretch film 13 is wrapped around the multiple impact-resistant plates 9. By setting up the fixed ring 3 and the movable ring shell 4 structure, the impact-resistant plate 9 has a rotation function. When subjected to external impact force, the impact-resistant plate 9 drives the movable ring shell 4 to rotate along the fixed ring 3 through the telescopic strip 8, the limiting shell 6, the mounting bolt 12 and the high-strength sleeve shell 5, so that the impact-resistant plate 9 can dissipate part of the impact force. The fixed ring 3 and the movable ring shell 4 structure makes it easy to rotate the impact-resistant plate 9 that needs to be replaced and maintained to a suitable disassembly angle, tear off the wrapping film 13, unscrew the mounting bolt 12 through the round hole 11 to the inside of the high-strength sleeve shell 5, and disassemble the limiting shell 6, thus facilitating the disassembly of the impact-resistant plate 9. Install the replaced and maintained limit shell 6 and impact-resistant plate 9 by installing the bolt 12, and wrap the new stretch film 13 to prevent fine dust and impurities from clogging the gaps of the impact-resistant plate 9 and to prevent the movement of the impact-resistant plate 9 from being obstructed.

[0020] Working principle: By setting up reinforcing steel bars 2 and high-strength sleeve shells 5, the strength of the stainless steel seamless steel pipe body 1 can be improved. The limiting shell 6 and the impact-resistant plate 9 are installed by the mounting bolt 12 and wrapped with a wrapping film 13 to prevent fine dust and impurities from clogging the gaps of the impact-resistant plate 9 and to prevent the movement of the impact-resistant plate 9 from being obstructed. The spring 7 uses its own elasticity to support the impact-resistant plate 9 through the telescopic bar 8. When the impact-resistant plate 9 is subjected to external impact, the elasticity of the spring 7 can offset the impact force, and the rubber pad 10 can use its own flexibility to buffer and protect the impact-resistant plate 9. By setting up a fixed ring 3 and a movable ring shell 4 structure, the impact-resistant plate 9 has a rotation function. When subjected to external impact force, the impact-resistant plate 9 drives the movable ring shell 4 to rotate along the fixed ring 3 through the telescopic bar 8, the limiting shell 6, the mounting bolt 12 and the high-strength sleeve shell 5, so that the impact-resistant plate 9 can dissipate part of the impact force.

[0021] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
