[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-4 , a wear-resistant seal that can be quickly replaced includes a first fixing sleeve 1, a second fixing sleeve 2 and a sealing member 3. A first fixing block 4 is provided on the outer wall of the first fixing sleeve 1, and a bolt 5 is rotatably connected in the first fixing block 4. A second fixing block 6 is provided on the outer wall of the second fixing sleeve 2. The threaded section of the bolt 5 is embedded in the second fixing block 6 and is threadedly connected with a nut 7. The nut 7 is located on the end of the second fixing block 6 facing away from the first fixing block 4. Both ends of the first fixing sleeve 1 and the second fixing sleeve 2 are rotatably connected with a rotating shaft 8. The rotating shaft 8 is located at one end outside the first fixing sleeve 1 and the second fixing sleeve 2 and is connected to an arc side plate 9. The other end of the rotating shaft 8 is connected to a spring sheet 10. A spring 11 is sleeved on the outer wall of the rotating shaft 8. The other end of the arc side plate 9 is connected to a positioning pin 12. The positioning pin 12 is located on the same side as the rotating shaft 8 and is respectively inserted into the end faces of the first fixing sleeve 1 and the second fixing sleeve 2.

[0022] The connection between the first fixing block 4 and the bolt 5 enables the bolt 5 to rotate in the first fixing block 4, thereby facilitating the bolt 5 to be embedded in the second fixing block 6. The connection between the bolt 5 and the nut 7 enables the bolt 5 to drive the nut 7 to rotate synchronously, and the screwing of the nut 7 on the bolt 5 causes extrusion between the first fixing block 4 and the second fixing block 6, thereby achieving the purpose of the first fixing sleeve 1 and the second fixing sleeve 2 squeezing the seal 3 onto the pipe. Conversely, the reverse screwing of the nut 7 on the bolt 5 without complete separation creates a gap between the nut 7 and the second fixing block 6, thereby facilitating the bolt 5 to drive the nut 7 to separate from the second fixing block 6, thereby achieving the purpose of the first fixing sleeve 1 and the second fixing sleeve 2 squeezing the seal 3 onto the pipe. The installation and disassembly between the first fixing sleeve 1 and the second fixing sleeve 2 is more convenient, thereby achieving the purpose of convenient replacement of the seal 3. Through the cooperation between the rotating shaft 8, the arcuate side plate 9, the spring sheet 10, the spring 11 and the positioning pin 12, the arcuate side plate 9 can provide a positioning effect for the installation of the seal 3, and when the seal 3 is replaced, the positioning pin 12 can be withdrawn by pulling the arcuate side plate 9 outward, and the arcuate side plate 9 rotates with the rotating shaft 8 as the center, thereby releasing the positioning of one side of the seal 3, so that the first fixing sleeve 1 and the second fixing sleeve 2 can be slid and separated from the seal 3 without being completely loosened, thereby making the replacement of the seal 3 more convenient and quick.

[0023] Specifically, in this embodiment, a first slot 13 is provided on the first fixing block 4, and support shafts 14 are connected to both ends of the nut section of the bolt 5. The two support shafts 14 are rotatably connected to the inner wall of the first slot 13. The support shafts 14 provide a rotation fulcrum for the rotation of the bolt 5 in the first fixing block 4, and ensure the stability of the bolt 5 when the nut 7 is tightened.

[0024] Specifically, in this embodiment, a second slot 15 is provided on the second fixing block 6. The width of the second slot 15 is the same as the diameter of the threaded section of the bolt 5 and is smaller than the width of the nut 7, ensuring that the threaded section of the bolt 5 is smoothly embedded in the second slot 15. At the same time, the extrusion between the nut 7 and the bolt 5 acts on the first fixing block 4 and the second fixing block 6.

[0025] Specifically, in this embodiment, a first sliding hole 16 is formed on the end surface of the first fixing sleeve 1 and the second fixing sleeve 2 , and the rotating shaft 8 is movably connected in the first sliding hole 16 to provide space for the sliding and rotation of the rotating shaft 8 .

[0026] Specifically, in this embodiment, a second sliding hole 17 is opened in the end surface of the first fixing sleeve 1 and the second fixing sleeve 2. The second sliding hole 17 is connected to the first sliding hole 16, and the aperture is larger than the aperture of the first sliding hole 16. The spring sheet 10 is movably connected in the second sliding hole 17, providing space for the sliding and rotation of the spring sheet 10.

[0027] Specifically, in this embodiment, the wall thickness of the arcuate side panel 9 at the end connected to the rotating shaft 8 is the same as the wall thickness of the first fixed sleeve 1 and the second fixed sleeve 2, and the wall thickness of the arcuate side panel 9 at the connection with the positioning pin 12 gradually increases, ensuring that the end of the arcuate side panel 9 connected to the rotating shaft 8 does not provide shielding for the seal 3 when rotating, facilitating the sliding separation between the two fixing sleeves and the seal 3, and ensuring that the arcuate side panel 9 can fully provide a positioning effect for the seal 3 when the positioning pin 12 is inserted.

[0028] Specifically, in this embodiment, a positioning hole 18 is opened on the end face of the first fixing sleeve 1 and the second fixing sleeve 2, and the positioning pin 12 is inserted into the positioning hole 18, which facilitates the insertion of the positioning pin 12. Under the action of the elastic force of the spring 11, the rotation of the arc-shaped side panel 9 is effectively restricted, providing stability of the positioning effect of the arc-shaped side panel 9.

[0029] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
