[0008] Preferably, the left and right side walls of the clamping block are fixedly connected to the limiting blocks, and the left and right inner walls of the blind hole are provided with limiting grooves matching the limiting blocks.

[0009] Preferably, a threaded rod is arranged in the through hole, and a thread matching the threaded rod is formed on the inner wall of the through hole near the outer side.

[0010] Preferably, an annular gasket is fixedly connected to the side wall of the annular connecting block.

[0011] Preferably, a plurality of evenly distributed fixing rods are fixedly connected to the left wall of the pipe body, and fixing holes matching the fixing rods are opened on the right wall of the pipe body, and the number of the fixing rods is the same as that of the fixing blocks.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] In the present technical solution, through the mutual cooperation between the spring, the fixed block and the fixed groove, when the two pipe bodies are docked, the fixed block is inserted into the fixed groove, and the spring drives the card block to be inserted into the through hole on the fixed block, thereby realizing the convenient connection of the two pipe bodies. At the same time, through the inclined setting of the fixed block and the inner wall of the fixed groove, the fixed block can more conveniently push the card block to move. When it can be disassembled again through the action of the threaded rod, the threaded rod can conveniently withdraw the card block out of the through hole, thereby realizing its convenient disassembly.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4The utility model provides a technical solution: a prestressed pipe pile joint, comprising a plurality of pipe bodies 1, annular connecting blocks 3 are sleeved at both ends of the pipe bodies 1, a plurality of evenly distributed fixing blocks 4 are fixedly connected to the side walls of the annular connecting blocks 3, and a plurality of fixing grooves 10 matching the fixing blocks 4 are provided on the side walls of the annular connecting blocks 3, the side walls of the fixing blocks 4 close to the fixing grooves 10 and the inner wall 10 of the fixing grooves are inclined, a blind hole is provided on the inner wall of the fixing grooves 10, a spring 8 is fixedly connected to the inner wall of the blind hole, and a clamping block 6 is fixedly connected to the other end of the spring 8, and the clamping block 6 is arc-shaped away from the side of the spring 8, a through hole matching the clamping block 6 is provided on the fixing block 4, the left and right side walls of the clamping block 6 are fixedly connected to the limiting blocks 7, and the left and right inner walls of the blind hole are provided with limiting grooves matching the limiting blocks 7, a threaded rod 5 is provided in the through hole, and the through hole A thread matching the threaded rod 5 is provided near the outer side of the inner wall of the hole, and an annular gasket 9 is fixedly connected to the side wall of the annular connecting block 3. A number of evenly distributed fixing rods 2 are fixedly connected to the left wall of the pipe body 1, and a fixing hole matching the fixing rod 2 is provided on the right wall of the pipe body 1. The number of fixing rods 2 and the fixing block 4 is the same. Through the mutual cooperation between the spring 8, the fixing block 4 and the fixing groove 10, when the two pipe bodies 1 are docked, the fixing block 4 is inserted into the fixing groove 10, and the spring 8 drives the card block 6 to be inserted into the through hole on the fixing block 4, so as to realize the convenient connection of the two pipe bodies 1. At the same time, through the inclined setting of the fixing block 4 and the inner wall of the fixing groove 10, the fixing block 4 can more conveniently push the card block 6 to move. When it can be disassembled again through the action of the threaded rod 5, the threaded rod 5 can conveniently withdraw the card block 6 from the through hole, thereby realizing its convenient disassembly.

[0021] Working principle: When the present technical solution is used, the fixing blocks 4 and the fixing rods 2 on the two pipe bodies 1 correspond to the relative fixing grooves 10 and the fixing holes respectively, and the two pipe bodies 1 are plugged in. When the fixing block 4 is plugged into the fixing groove 10, the card block 6 will be pushed to retract into the blind hole and the spring 8 will be compressed. When the through hole on the fixing block 4 is aligned with the card block 6, under the action of the spring 8, the card block 6 is inserted into the through hole to achieve convenient connection. When disassembling, the threaded rod 5 is rotated and moved to push the card block 6 out of the through hole, thereby achieving convenient disassembly.
