The inner lining sleeve 1 is used to prevent the direct scouring of the inner wall of the bellows by the flowing medium, reduce wear, and extend the service life. The pipe body 2 can absorb axial, lateral and angular displacements and vibrations in the pipeline system. The protective cover one 3 is used to protect the bellows, the protective cover two 4 is used to protect the bellows, the baffle 5 is used to fix the protective cover one 3, the fixing block one 6 is used to fix the connecting rod 8, the fixing block two 7 is used to fix the connecting rod 8, the connecting rod 8 is used to fix the sleeve 9, the sleeve 9 is used to fix the spring 10, the spring 10 can drive the sleeve 9 to reset through the pulling force, the buckle 11 is used to fix the protective cover one 3, and the pull rod 12 is used to drive the buckle 11 to move.

[0034] Referring to Figure 1 , Figure 2 and Figure 4 , an anti-corrosion component is arranged on the outer periphery of the inner lining sleeve 1, and the anti-corrosion component is used to extend the service life of the inner lining sleeve 1. The anti-corrosion component includes an anti-corrosion coating 13, the anti-corrosion coating 13 is coated on the outer periphery of the inner lining sleeve 1, and a wear-resistant coating 14 is coated on the outer periphery of the anti-corrosion coating 13. The anti-corrosion coating 13 can effectively prevent the chemical substances in the medium from reacting with the material of the inner lining sleeve 1, avoid the material from being corroded or oxidized, thereby extending the service life of the inner lining sleeve 1. The wear-resistant coating 14 can significantly improve the wear resistance of the inner lining sleeve 1 and reduce the influence of wear on the inner lining sleeve 1.

Both the front and rear sides of the bottom of the first protective cover 3 are fixedly connected with stabilizing plates 15. The outer peripheries of the stabilizing plates 15 are slidably connected inside the second protective cover 4. Both the left and right sides of the inner lining sleeve 1 are fixedly connected with limiting plates 16. The outer peripheries of the limiting plates 16 are fixedly connected with a plurality of uniformly distributed fixing plates 18. A plurality of uniformly distributed ventilation openings are provided at the top of the first protective cover 3.

Two nuts 20 are threadedly connected to the outer periphery of the bolt 19. The material of the anti-corrosion coating 13 is epoxy resin, and the material of the wear-resistant coating 14 is ceramic. The stabilizing plates 15 can make the connection between the first protective cover 3 and the second protective cover 4 more compact.

The bolt 19 is used to limit the excessive displacement of the corrugated pipe, preventing damage due to excessive force during installation or operation. The nuts 20 are used to fix the bolt 19. Using epoxy resin as the material for the anti-corrosion coating 13 can endow it with excellent anti-corrosion performance, capable of effectively resisting the erosion of acids, alkalis, salts and other chemical media. Using ceramic as the material for the wear-resistant coating 14 can endow it with extremely high hardness and wear resistance.

[0036] Working principle: When the operator pulls the pull rod 12, the pull rod 12 will drive the buckle 11 to slide along the guide and place the buckle 11 in the preset card slot of the baffle 5. At this time, the buckle 11 is fixed to the baffle 5, and at the same time, the first protective cover 3 and the second protective cover 4 are locked together to form a complete protective shell. Subsequently, the spring 10 in the device restores the sleeve 9 through its resilience, ensuring the stability of the buckle 11 and preventing it from accidentally loosening under external forces. Through this series of operations, the protective cover can reliably protect the corrugated pipe from the external environment. In addition, the protective cover also plays an isolation role, preventing the corrugated pipe from interfering with surrounding equipment during operation, thus ensuring the operation safety of the entire equipment. A layer of anti-corrosion coating 13 is evenly coated on the outer periphery of the inner lining sleeve 1, which can effectively isolate corrosive substances in the pipeline medium, such as acids, alkalis and salts, and prevent these chemical substances from directly contacting the metal of the inner lining sleeve 1, thereby preventing the corrosion and oxidation of the material and increasing the service life of the inner lining sleeve 1. On the outer periphery of the anti-corrosion coating 13, a layer of wear-resistant coating 14 is further coated, which can make it have extremely high hardness and wear resistance, capable of resisting the erosion and wear of solid particles or high-speed flowing liquids in the medium on the surface of the inner lining sleeve 1, thereby not only protecting the inner lining sleeve 1 from physical wear, but also reducing the risk of equipment performance degradation or failure caused by wear.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used 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 recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
