[0018] See also Figure 1-3The utility model provides a technical solution: a leakage-proof JDG pipe joint, comprising a joint sleeve 1 and a JDG pipe body 3, the inner wall of the joint sleeve 1 is provided with a sealing ring 6 and a sealing ring 7 in sequence, both ends of the joint sleeve 1 are provided with a fixing ring 2, the inner walls of the two groups of fixing rings 2 are connected with a reinforcement ring 5, and the top and bottom outer walls of the fixing ring 2 are provided with a U-shaped box 4, the top and bottom walls of the JDG pipe body 3 are provided with a clamping hole 12, the top and bottom walls of the fixing ring 2 are provided with a through hole 8, and the top and bottom ends of the reinforcement ring 5 are provided with a through groove 9 connected with the clamping hole 12 and the through hole 8, and a disassembly and assembly mechanism matched with the clamping hole 12 is provided in the U-shaped box 4, and the disassembly and assembly mechanism includes a locking block 11.

[0019] The joint sleeve 1 is fixedly connected to the two sets of fixing rings 2, and the U-shaped box 4 is fixedly installed on the fixing ring 2. When the JDG tube body 3, the fixing ring 2 and the joint sleeve 1 are installed, the clamping hole 12 opened on the JDG tube body 3 is aligned with the through groove 9 and the through hole 8 until the adjacent JDG tube bodies 3 are in contact with each other. The reinforcement ring 5, the sealing ring 6 and the sealing ring 7 are arranged to improve the sealing performance of the connection between the JDG tube body 3, the joint sleeve 1 and the fixing ring 2 to avoid leakage. When the sleeve 1 is installed, the locking block 11 is connected to the corresponding clamping hole 12, which completes the fixation of the JDG tube body 3. When disassembling, the locking block 11 in the U-shaped box 4 is separated from the clamping hole 12. When the JDG tube body 3 needs to be disassembled, the locking block 11 is separated from the clamping hole 12. At this time, the JDG tube body 3 is no longer restricted, and the JDG tube body 3 can be removed from the joint sleeve 1 and the fixing ring 2, thereby realizing the rapid disassembly and assembly of the JDG tube and the joint, replacing the traditional installation using bolts, without the need for tools, and improving work efficiency.
