[0032] Please see the appendix Figure 2 Appendix Figure 4 and attached Figure 5 An embodiment of this utility model provides a low-temperature explosion-proof inner lining reinforcement device for fiberglass pipes, including an inner lining pipe 1, a pipe body 3 fixedly connected to the outer wall of the inner lining pipe 1, multiple grooved rings 4 provided on the inner wall of the inner lining pipe 1, grooves 5 opened on the outer wall of the grooved rings 4, multiple elastic blocks 6 fixedly connected to the inner wall of the grooves 5, a fixing ring 7 fixedly connected to the top of the elastic blocks 6, a rotating shaft 8 provided on both the left and right sides of the outer wall of the inner lining pipe 1, a limit ring 9 rotatably connected to the front and rear sides of the outer wall of the rotating shaft 8, screws 10 threadedly connected to the top front left and right ends of the limit ring 9, an installation mechanism 2 provided on both the left and right sides of the outer wall of the inner lining pipe 1, the installation mechanism 2 being used to connect to another identical device, a protective layer 11 fixedly connected to the outer wall of the pipe body 3, and an anti-corrosion coating 12 fixedly connected to the outer wall of the protective layer 11.
[0033] Specifically, the inner liner 1 is fixedly connected to the pipe body 3, ensuring a tight fit between the two. The grooved ring 4 not only enhances the structural strength of the pipe body 3 but also facilitates subsequent maintenance and replacement. The elastic block 6 acts as a buffer and shock absorber during pipeline operation, ensuring the stability of fluid transport. The fixed ring 7 further ensures reliability under extreme working conditions. The rotating shaft 8 allows the pipeline to make necessary angle adjustments under specific conditions to adapt to different installation environments. The limiting ring 9 is designed to prevent the rotating shaft 8 from over-rotating, thereby protecting the entire pipeline structure from damage.

[0034] Please see the appendix Figure 1 Appendix Figure 2and attached Figure 3 The installation mechanism 2 includes a lubrication layer 201. The inner wall of the lubrication layer 201 is fixedly connected to the outer wall of the inner liner tube 1. Limiting rails 202 are provided on the front and rear ends of the left and right sides of the outer wall of the inner liner tube 1. Sealing rings 205 are fixedly connected to the left and right sides of the inner liner tube 1 near the edge.

A sealing ring 16 is fixedly connected to the inner wall of the limiting ring 9.
[0035] Specifically, the lubrication layer 201 is fixedly connected to the inner liner tube 1, ensuring a seamless connection between the two. The limiting track 202 not only provides precise positioning for the inner liner tube 1 but also enhances its stability during use. The sealing ring 205 ensures the sealing between the inner liner tube 1 and the lubrication layer 201 while also protecting the surface of the inner liner tube 1. The retaining ring 204 is designed to prevent unnecessary displacement of the lubrication layer 201 during movement, thereby ensuring the stable operation of the entire system. The lubrication layer 201 is slidably connected to the connecting ring 203, allowing the connecting ring 203 to slide freely on the outer wall of the lubrication layer 201 while maintaining a tight connection. The connecting ring 203 is threadedly connected to the screw 206, which is not only firm and reliable but also easy to disassemble and maintain. The gasket 13 disperses pressure, reduces friction between the screw 206 and the connecting ring 203, and extends service life. The sealing ring 16 further enhances the sealing effect between the limiting ring 9 and the inner liner tube 1, ensuring the sealing performance of the entire system.
[0036] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 The outer wall of screw 10 is provided with washer 15, and the rear side of the outer wall of screw 10 is threaded with nut 14. The outer wall of fixing ring 7 is slidably connected to the inner wall of elastic block 6, and multiple elastic blocks 6 are arranged symmetrically.
[0037] Specifically, screw 2 10 is equipped with washer 2 15, which not only enhances the stability of screw 2 10, but also effectively prevents potential damage to the connecting parts caused by over-tightening.

The retaining ring 7 is slidably connected to the elastic block 6, allowing the retaining ring 7 to move freely within a certain range, thereby adapting to minor deformations under different working environments. The multiple elastic blocks 6 are symmetrically distributed, ensuring uniform force transmission and improving the stability and load-bearing capacity of the overall structure.
[0038] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3The bottom of the outer wall of screw 206 is threaded to the top of the inner wall of the inner liner tube 1. The left end of the right retaining ring 204 is fixedly connected to the right side of the protective layer 11. The outer wall of the limiting rail 202 is slidably connected to the front and rear sides of the inner wall of the connecting ring 203. The two limiting rails 202 are symmetrically arranged.
[0039] Specifically, screw 206 is threadedly connected to the inner liner tube 1, ensuring a tight connection and stable force transmission between the two. The retaining ring 204 is fixedly connected to the protective layer 11, which not only enhances the stability of the structure but also provides additional protection for the internal components. The limiting rail 202 is slidably connected to the connecting ring 203, making the entire mechanical device more flexible and efficient in operation. The limiting rails 202 are symmetrically arranged, ensuring the balance and uniformity of the mechanical device during operation, thereby improving the overall performance and reliability.
[0040] Working principle: When the temperature drops, due to thermal expansion and contraction, the tube body 3 will begin to shrink, which will then squeeze the inner liner tube 1. The inner liner tube 1 will squeeze the inner fixing ring 7. After being squeezed, the fixing ring 7 will slide into the groove 5 and the pressure will be offset by the elastic block 6. After the inner liner tube 1 is slid into the tube body 3, the limiting ring 9 is rotated so that the limiting ring 9 limits the tube body 3 and the inner liner tube 1 together, preventing it from slipping out during use. Then, the screw 10 is turned, which can fix the limiting rings 9 on both sides. This can achieve the reinforcement and installation of the inner liner tube 1, improve the strength and toughness of the inner liner tube 1, and prevent the tube body 3 from easily breaking due to the drop in temperature.
[0041] If the tube body 3 needs to be extended, align the connecting ring 203 with the limiting rail 202 and push the connecting ring 203 so that the connecting ring 203 slides along the outer wall of the limiting rail 202. The lubricating layer 201 makes the sliding of the connecting ring 203 smoother. When the connecting ring 203 touches the retaining ring 204, it stops sliding. Then slide the other inner liner tube 1 to the other side of the inside of the connecting ring 203 in the same way. Finally, tighten the screw 206 to fix the inner liner tubes 1 on both sides, thus extending the tube body 3, which is convenient for users and improves the adaptability of the equipment.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
