The mounting sleeve 2 is fitted onto the outer wall of the microwave communication waveguide 1. The microwave communication waveguides 1 are connected by screwing together the threaded splicing ring 13 and the threaded splicing groove 14, which allows the microwave communication waveguides 1 to be quickly connected to each other.

[0022] Mounting sleeve 2 is fitted and rotated onto microwave communication waveguide 1. Mounting sleeve 2 is locked and fixed to microwave communication waveguide 1 through threaded mounting groove 6 and locking bolt 7. This allows mounting sleeve 2 to be quickly inserted and rotated onto microwave communication waveguide 1. Mounting sleeve 2 can also be locked and positioned by threaded mounting groove 6 and locking bolt 7. Mounting sleeve 2 is installed in a sealed splice within sealing groove 10 by sealing ring 5. The connection between mounting sleeve 2 and microwave communication waveguide 1 is wrapped and distributed, which allows mounting sleeve 2 to be sealed and combined, thereby wrapping the connection of microwave communication waveguide 1 and providing effective protection.

[0023] A threaded splicing groove 14 is provided on one edge of the microwave communication waveguide 1, and a threaded splicing ring 13 is fixedly connected to the protruding edge of the other edge of the microwave communication waveguide 1. The threaded splicing ring 13 is inserted into the threaded splicing groove 14. A threaded mounting groove 6 is provided in the middle of the outer wall of the mounting sleeve 2, and a locking bolt 7 is inserted into the inner wall of the threaded mounting groove 6. Sliding grooves 15 are provided on both sides of the outer wall of the mounting sleeve 2, and sliding locking blocks 11 are slidably inserted into the inner wall of the sliding grooves 15. A fixed bracket 3 is fitted onto the outer wall of the sliding locking block 11, and telescopic grooves 8 are provided on both sides of the lower end of the inner wall of the fixed bracket 3. The fixed bracket 3 and the fixed bolt 4 are distributed in two groups on the mounting sleeve 2, and the fixed bracket 3 is slidably connected to the mounting sleeve 2 through the sliding locking block 11 and the sliding groove 15. This makes it easy to slide and adjust the fixed bracket 3 and the fixed bolt 4 to adapt to different installation environments.

[0024] The fixed bracket 3 is installed in the sliding groove 15 by inserting and splicing the mounting sleeve 2 through the sliding locking block 11. The sliding locking block 11 is elastically telescopically connected to the telescopic groove 8 and the sliding groove 15 through the connecting spring 12. This makes it easy to quickly assemble and disassemble the fixed bracket 3 and the mounting sleeve 2 and to replace it independently. The upper end of the sliding locking block 11 is inserted and installed in the telescopic groove 8. The upper end of one side of the telescopic groove 8 is fixedly connected to the connecting spring 12. The other end of the connecting spring 12 is fixedly connected to the inner wall of the telescopic groove 8. The upper end of the other side of the sliding locking block 11 is protruding and fixedly connected to the push block 9.

The inner wall of the fixed bracket 3 is inserted and installed with the fixing bolt 4.

[0025] Working principle: When using the connection structure of this microwave communication waveguide, firstly, the mounting sleeve 2 of the device is fitted onto the outer wall of the microwave communication waveguide 1. Then, the microwave communication waveguides 1 are rotated and assembled using the threaded splicing ring 13 and the threaded splicing groove 14. Next, the microwave communication waveguides 1 are bolted and installed using the fixing bracket 3 and the fixing bolt 4. To adapt to different installation environments, the fixing bracket 3 and the fixing bolt 4 can be slidably adjusted using the sliding locking block 11 and the sliding groove 15. During installation, the mounting sleeve 2 can be sealed and assembled using the sealing ring 5 and the sealing groove 10, thereby sealing and wrapping the connection of the microwave communication waveguide 1. The mounting sleeve 2 is then locked and fixed using the threaded mounting groove 6 and the locking bolt 7. When the fixing bracket 3 and the fixing bolt 4 are damaged, the sliding locking block 11 can be elastically contracted by the connecting spring 12 to release the installation and allow for quick disassembly and replacement. This is the usage process of the connection structure of this microwave communication waveguide.
