[0032] The anti-skid ring 16 is crimped between the threaded head 15 and the protected pipe 13, the first hole 17 is arranged in the half-round shell 1, the inner wall of the first hole 17 is slidably connected with the first bolt 4, the inner wall of the first bolt 4 is threadedly connected with the first nut 5, the lower end of the first nut 5 is in close contact with the half-round shell 1, the lower surface of the spring 6 is fixedly connected with the first fixing part 3, the upper surface of the spring 6 is in close contact with the half-round shell 1, the outer surface of the half-round inner shell 11 is fixedly connected with the sponge 2, the outer surface of the sponge 2 is in close contact with the inner wall of the half-round shell 1, the bottom of the half-round shell 1 is fixedly connected with the second fixing part 7, the inside of the second fixing part 7 is provided with the second hole 18, the inside of the second hole 18 is provided with the second bolt 8, the outer surface of the second bolt 8 is threadedly connected with the second nut 9, the number of the half-round shell 1 is two and symmetrically distributed, the number of the half-round inner shell 11 is two and symmetrically distributed, the anti-seepage strip 19 is arranged on the outer side of the anti-skid ring 16 close to one end of the second fixing part 7, and the waterproof filling strip 10 is crimped on the inner side of the second fixing part 7.

[0033] Working principle: the device is composed of two symmetrical half-circular outer shells 1 and half-circular inner shells 11. During installation, the two half-circular inner shells 11 are respectively sleeved on both sides of the protected pipe 13, so that the rubber filling block 12 is in close contact with the outer wall of the protected pipe 13. Then, the two half-circular outer shells 1 are squeezed towards the middle, so that they gradually surround the protected pipe 13. During the squeezing process, as the half-circular outer shells 1 approach, the pressure is transmitted to the first fixing member 3 through the half-circular inner shells 11, and the first fixing member 3 drives the first bolt 4 to move upwards in the first hole 17 and the second hole 18 of the half-circular outer shell 1.

[0034] When the second fixing member 7 at the lower end of the half-circular outer shell 1 is in complete contact with the second fixing member 7 at the symmetrical position, the second bolt 8 is passed through the second hole 18 of the second fixing member 7, and the second nut 9 is tightened, thereby firmly fixing the two half-circular outer shells 1 together. At the same time, the first nut 5 is used to fix the extruded first bolt 4. The entire protection device is completed on the protected pipe 13. The outside of the first bolt 4 is sleeved with a spring 6, the lower surface of the spring 6 is fixedly connected with the first fixing member 3, and the upper surface is in close contact with the half-circular outer shell 1. During the installation and subsequent use of the squeezed half-circular outer shell 1, when the protected pipe 13 is subjected to external pressure, vibration or impact, the pressure will be transmitted to the first fixing member 3 through the rubber filling block 12 and the half-circular inner shell 11, and then the first bolt 4 drives the spring 6 to compress or elongate and other elastic deformation. The elastic deformation of the spring 6 can provide stable support, effectively buffer and absorb part of the energy applied to the protected pipe 13 by the external force, thereby reducing the impact force on the protected pipe 13. At the same time, the spring 6 structure can adaptively adjust according to the size of the external force, so that the protection device can adapt to the slight deformation of the protected pipe 13 within a certain range due to external force, and always maintain effective protection for the protected pipe 13.

[0035] A sponge 2 is arranged between the half-circular outer shell 1 and the half-circular inner shell 11. The sponge 2 has good elasticity and buffering performance, and can further absorb energy when the device is subjected to external vibration or impact, thereby playing an auxiliary buffering and damping role and enhancing the anti-scratch protection effect. At the same time, it can also reduce the friction between the half-circular outer shell 1 and the half-circular inner shell 11, thereby avoiding damage to the device caused by friction. The inner side of the second fixing member 7 at the contact position of the two half-circular outer shells 1 is press-bonded with a waterproof filling strip 10. When the two half-circular outer shells 1 are fixed by the second bolt 8 and the second nut 9, the waterproof filling strip 10 is tightly squeezed between the second fixing members 7, forming a waterproof barrier to prevent water from penetrating into the device and contacting the protected pipe 13 from the connection between the two half-circular outer shells 1. This can prevent the outer wall of the protected pipe 13 from rusting and corroding due to moisture.

[0036] Threaded heads 15 are arranged at the front ends of the two semicircular shells 1, the threaded heads 15 are connected and fixed at the designated positions by rotating the threaded fixing ring 14, and the anti-skid ring 16 is pressed between the inner wall of the threaded head 15 and the protected pipe 13, the anti-skid ring 16 increases the friction between the protection device and the protected pipe 13, effectively prevents the displacement of the protection device on the protected pipe 13, and ensures that the protection device always stably protects the protected pipe 13 during use, and the anti-seepage strips 19 are arranged between the two threaded heads 15, the anti-seepage strips 19 can block rainwater, impurities and the like from entering the inside of the protection device from the connection of the threaded heads 15, together with the waterproof filling strips 10, prevent the contact of external liquids and impurities with the protected pipe 13 from different positions, and prolong the service life of the protected pipe 13.

[0037] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
