[0013] Preferably, a sealing structure is provided on the pipe body, and the sealing structure is mainly composed of a sealing ring. The sealing ring is provided on the pipe body, and one end of the pipe body is fixedly connected to a sealing groove.

[0014] The effect achieved by the above components is that when two pipe bodies are connected, the sealing ring is stuck in the sealing groove, which can improve the sealing performance of the connection.

[0015] Preferably, a plurality of locking rods are fixedly connected to the sealing ring, and a plurality of locking grooves are formed at one end of the pipe body.

[0016] The effect achieved by the above components is that the sealing ring can be installed by inserting the locking rod into the locking groove, and vice versa, the sealing ring can be removed and replaced.

[0017] Preferably, a circular groove is provided on the locking rod, a telescopic column is fixedly connected in the circular groove, a round ball is fixedly connected to one end of the telescopic column, and a locking groove is provided in the locking groove.

[0018] The effect achieved by the above components is: stretching the telescopic column allows the ball to be clamped into the clamping groove, which can limit the clamping rod and make the installation of the sealing ring more stable.

[0019] Preferably, a third spring is sleeved on the telescopic column, one end of the third spring is fixedly connected to the round ball, and the other end of the third spring is fixedly connected to the inner wall of the circular groove.

[0020] The effect achieved by the above components is: when the locking rod is locked into the locking groove, the inner wall of the locking groove will push the arc surface of the ball, so that the ball is retracted into the circular groove, which will squeeze the third spring to contract. When the ball contacts the locking groove, the ball is locked into the locking groove under the action of the rebound force of the third spring. Otherwise, the sealing ring can be easily removed, making the replacement operation more convenient.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are that, in the present invention, by setting a connecting mechanism, the two connecting blocks on one pipe body are inserted into the connecting grooves on the adjacent pipe bodies, so that the two pipe bodies can be connected together.

The slide block 24 can be pushed downward by pressing the slide bar 28, which facilitates the disassembly of the pipe body 1. When the slide bar 28 is pressed downward, the second spring 29 is squeezed and contracted, so that the slide bar 28 is located at the top without external force, so that the slide bar 28 does not contact the slide block 24. When connecting the two pipe bodies 1, the sealing ring 31 is inserted into the sealing groove 32, which can improve the sealing of the connection. The sealing ring 31 can be installed by inserting the locking rod 33 into the locking groove 34. Otherwise, the sealing ring 31 can be removed for replacement. , stretching the telescopic column 36 allows the ball 37 to be stuck into the slot 38, which can limit the positioning rod 33, making the installation of the sealing ring 31 more stable. When the positioning rod 33 is stuck into the positioning groove 34, the inner wall of the positioning groove 34 will push the arc surface of the ball 37, so that the ball 37 is retracted into the circular groove 35, which will squeeze the third spring 39 to contract. When the ball 37 contacts the slot 38, the ball 37 is stuck into the slot 38 under the action of the rebound force of the third spring 39. Otherwise, the sealing ring 31 can be easily removed, making the replacement operation more convenient.
