[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] The following describes an embodiment of the present invention with reference to the accompanying drawings: a leak-proof steel pipe for butt joints.

[0019] like Figures 1-5 As shown in the figure, a leak-proof steel pipe according to an embodiment of the present invention includes: a connecting steel pipe 1 and a sealing mechanism 2.

[0020] The sealing mechanism 2 includes a first sealing ring 21, a first spring 22, a push plate 24, and a second sealing ring 25. The first sealing ring 21 is disposed on the outer wall of the connecting steel pipe 1, the first spring 22 is disposed inside the connecting steel pipe 1, and one end of the first spring 22 is connected to the connecting steel pipe 1. The push plate 24 is connected to the other end of the first spring 22, and the second sealing ring 25 is disposed on the outer wall of the push plate 24.

[0021] Specifically, the first sealing ring 21 is set on the outer wall of the first steel pipe 11 to prevent external moisture or gas from entering the interior of the connecting steel pipe 1, thus ensuring the sealing performance of the steel pipe. Through the cooperation of the first spring 22, the push plate 24 and the second sealing ring 25, when the second sealing ring 25 is squeezed, the first spring 22 will deform, thereby pushing the push plate 24 and the second sealing ring 25 to move, so that the second sealing ring 25 can fit better at the connection, further enhancing the sealing effect and preventing leakage. In addition, when the second sealing ring 25 is worn, the elastic force of the first spring 22 can automatically compensate for the wear of the second sealing ring 25, extending the service life of the sealing mechanism 2.

[0022] In one embodiment of this application, such as Figure 1As shown, the connecting steel pipe 1 includes a first steel pipe 11 and a second steel pipe 12.

[0023] One end of the second steel pipe 12 is connected to the first steel pipe 11.

[0024] Specifically, the first steel pipe 11 and the second steel pipe 12 can be connected by the mounting component 3, making the connection between the two more stable and facilitating disassembly and replacement.

[0025] In one embodiment of this application, such as Figure 4 As shown, an installation component 3 is installed on the connecting steel pipe 1.

[0026] The installation component 3 includes a slot 31, a moving ring 34, a second limiting block 35, and a retaining ball 38. The second steel pipe 12 has a slot 31, the moving ring 34 is located outside the first steel pipe 11, the second limiting block 35 is located on the inner wall of the moving ring 34, the first steel pipe 11 has a limiting groove 37, and the locking ball 38 is located inside the limiting groove 37.

[0027] Specifically, when connecting the first steel pipe 11 and the second steel pipe 12, the moving ring 34 is first moved towards the first limiting block 32, causing the second limiting block 35 to disengage from the retaining ball 38 in the limiting groove 37. Then, the first steel pipe 11 and the second steel pipe 12 are joined together. After joining, the moving ring 34 is moved away from the first limiting block 32, causing the second limiting block 35 to re-limit the retaining ball 38 in the limiting groove 37, thereby engaging the retaining ball 38 into the retaining groove 31 on the second steel pipe 12, thus completing the connection between the first steel pipe 11 and the second steel pipe 12. When it is necessary to disassemble the first steel pipe 11 and the second steel pipe 12, simply move the moving ring 34 toward the first limiting block 32 so that the second limiting block 35 disengages from the limiting ball 38 in the limiting groove 37, and then remove the ball 38 from the slot 31 on the second steel pipe 12. This completes the disassembly of the first steel pipe 11 and the second steel pipe 12. The disassembly process is simple and convenient, requires no additional tools, and improves disassembly efficiency.

[0028] In one embodiment of this application, such as Figure 5 As shown, the first spring 22 has a limiting post 23 inside, and one end of the limiting post 23 is connected to the first steel pipe 11, while the other end of the limiting post 23 is connected to the push plate 24.

[0029] Understandably, the limiting post 23 can guide and support the first spring 22, making the first spring 22 more stable during deformation and preventing the first spring 22 from failing due to excessive deformation. At the same time, the limiting post 23 can also limit the push plate 24, preventing the push plate 24 from moving excessively under the elastic force of the first spring 22, thereby ensuring the stability and reliability of the sealing mechanism 2.

[0030] In one embodiment of this application, such as Figure 4 As shown, an anti-slip sleeve 36 is provided on the outer wall of the movable ring 34.

[0031] Understandably, the anti-slip sleeve 36 increases friction when holding the moving ring 34, preventing the moving ring 34 from slipping or falling off due to wet hands or insufficient strength, thereby improving the safety and stability of operation.

[0032] In one embodiment of this application, such as Figure 4 As shown, a first limiting block 32 is provided on the outer wall of the first steel pipe 11.

[0033] Understandably, the first limiting block 32 can support and limit the second spring 33, ensuring the stability of the moving ring 34 during the reset process.

[0034] In one embodiment of this application, such as Figure 4 As shown, a second spring 33 is provided on the outer wall of the first steel pipe 11.

[0035] Understandably, by setting the second spring 33, when the moving ring 34 moves toward the first limiting block 32 and compresses the second spring 33, the second spring 33 will generate elastic force, which helps the moving ring 34 to automatically reset during disassembly or connection, thereby improving the convenience and efficiency of operation. In addition, the setting of the second spring 33 further enhances the overall stability of the connecting steel pipe 1, making the connection between the first steel pipe 11 and the second steel pipe 12 more reliable and less prone to loosening or falling off.

[0036] Working principle: First, the first sealing ring 21, located on the outer wall of the first steel pipe 11, prevents external moisture or gas from entering the interior of the connecting steel pipe 1, ensuring the sealing performance of the steel pipe. Through the cooperation of the internal first spring 22, push plate 24, and second sealing ring 25, when the second sealing ring 25 is compressed, the first spring 22 deforms, thereby pushing the push plate 24 and the second sealing ring 25 to move, allowing the second sealing ring 25 to better fit the connection, further enhancing the sealing effect and preventing leakage. Furthermore, when the second sealing ring 25 wears, the elastic force of the first spring 22 automatically compensates for the wear, extending the service life of the sealing mechanism 2. Simultaneously, when connecting the first steel pipe 11 and the second steel pipe 12, the moving ring 34 is first moved towards the first limiting block 32, causing the second limiting block 34 to... The positioning block 35 disengages from the retaining ball 38 in the limiting groove 37, then the first steel pipe 11 and the second steel pipe 12 are connected. After connection, the moving ring 34 is moved away from the first limiting block 32, so that the second limiting block 35 re-limits the retaining ball 38 in the limiting groove 37, thereby locking the retaining ball 38 into the retaining groove 31 on the second steel pipe 12, thus completing the connection between the first steel pipe 11 and the second steel pipe 12. When it is necessary to disassemble the first steel pipe 11 and the second steel pipe 12, simply move the moving ring 34 towards the first limiting block 32, so that the second limiting block 35 disengages from the retaining ball 38 in the limiting groove 37, and then remove the retaining ball 38 from the retaining groove 31 on the second steel pipe 12, thus completing the disassembly of the first steel pipe 11 and the second steel pipe 12. The disassembly process is simple and convenient, requiring no additional tools, thus improving disassembly efficiency.

[0037] In summary, this utility model provides a leak-proof steel pipe connection. By setting up a sealing mechanism 2, it significantly improves the sealing performance of the steel pipe connection, effectively preventing leakage. In addition, through the synergistic action of the internal first spring 22, push plate 24, and second sealing ring 25, automatic compensation for wear of the second sealing ring 25 is achieved, thereby extending the service life of the sealing mechanism 2, eliminating safety hazards caused by sealing failure, further enhancing the reliability and safety of the steel pipe, avoiding frequent disassembly and installation that could damage the steel pipe, and effectively reducing maintenance costs.
