[0021] The alignment device 2 includes a nut 12 and a clamp 13. The nut 12 is symmetrically threaded on the rear end of the clamp 13. The covering device 3 includes an alignment groove 14, a guide groove 15, a second protective cover 16 and a sealing ring 17. The sealing ring 17 is symmetrically fixed on the inner ring of the second protective cover 16. The guide grooves 15 are symmetrically opened at both ends of the second protective cover 16. The alignment groove 14 is opened at one end of the guide groove 15 close to the sealing ring 17. The interior of the second protective cover 16 is set in a hollow state so that it can be ring-fitted on the outer ring of the clamp 13.

[0022] The second protective cover 16 is slidably sleeved on the clamp 13 , and one end of the clamp 13 close to the nut 12 is slidably inserted into the interior of the supporting back plate 10 , allowing the clamp 13 to dock with the supporting back plate 10 .

[0023] Two sealing rings 17 are arranged on the front inner circle of the arc plate 7 , and are respectively fitted to the outer surface of the pipeline through the second protective cover 16 and the arc plate 7 on the arc plate 7 , so as to prevent external rainwater from contacting the clamp 13 .

[0024] The positioning key 9 is inclined at 30° away from the side surface of the supporting back plate 10 , so as to improve the smoothness of the guide groove 15 passing through the positioning key 9 .

[0025] Round holes are provided at both ends of the inner side of the support back plate 10 , and threads are provided at both ends of the rear side of the support back plate 10 away from the arc plate 7 , so as to facilitate the first protective cover 11 to fit and align with the support back plate 10 .

[0026] Working principle: When in use, first fix and weld the end of the support back plate 10 away from the arc plate 7 to the surface of the external equipment, and then place the external pipe inside the front end of the arc plate 7. After that, the threaded rod of the clamp 13 close to the nut 12 can be passed through the circular holes at both ends of the inside of the support back plate 10, and then the nut 12 can be screwed and sleeved on the threaded rod on the clamp 13 until the nut 12 is screwed and rotated to drive the clamp 13 to squeeze the pipe and the arc plate 7 to tighten, completing the restricted positioning of the pipe. After that, the first protective cover 11 is moved onto the nut 12, and the first protective cover is screwed. The cover 11 is adapted to the threads inside the rear end of the support back plate 10 until the first protective cover 11 is fastened to the support back plate 10 to complete the protection work of the nut 12, and then the second protective cover 16 is slid to the clamp 13 and connected to the clamp 13, and the guide groove 15 is driven by the second protective cover 16 to contact the positioning key 9, so that the second protective cover 16 is sleeved on the outer ring of the clamp 13, and then, the end surface of the guide groove 15 away from the alignment groove 14 is inclined at 45°, and the positioning key 9 is inclined at 30° away from the side end surface of the support back plate 10, so that the guide groove can be lifted. 15 Through the smoothness of the positioning key 9, when the second protective cover 16 moves to the limit position, the sealing ring 17 can be driven to fit tightly with the external pipe surface, and the positioning key 9 can be vertically aligned with the alignment groove 14. At this time, the elasticity of the return spring 4 will drive the positioning key 9 to insert into the inside of the alignment groove 14, so that the second protective cover 16 can be restricted and fixed. At this time, the sealing ring 17 on the arc plate 7 and the sealing ring 17 on the second protective cover 16 are both tightly fitted with the external pipe surface, so that rainwater from the outside can be prevented from entering the inside of the second protective cover 16, avoiding jamming. The hoop 13 is rusted. When the clamp 13 needs to be repaired, the sliding rods 5 at both ends of the supporting back plate 10 can be pulled toward the end away from the arc plate 7, so that the positioning key 9 can be moved out from the inside of the alignment groove 14, releasing the second protective cover 16. Thereafter, the second protective cover 16 is pulled toward the front end, so that the clamp 13 can be exposed, which is convenient for the user to repair the clamp 13. When the device is in use, the length of the first protective cover 11 is greater than the length of the threaded rod at the end of the clamp 13 close to the nut 12, so that the first protective cover 11 can be prevented from being unable to be installed and the work is completed.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
