[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention provides a pipe connector that is easy to quickly disassemble and install. When connecting a female connector and a male connector, a connection mechanism that is easy to fix is ​​provided, so the female connector and the male connector can be firmly connected, the operation is convenient and not easy to loosen.

When the inner swivel ring 3 rotates in the female connector 1, the sealing performance at the inner swivel ring 3 can be increased. A thread is provided on the inner wall of the inner swivel ring 3 and is matched and connected with the thread of the outer wall of the first insertion section 201. A conical gear ring 4 is arranged on the outer wall of the inner swivel ring 3. A top cavity 5 is arranged in the end of the female connector 1. A torsion column 6 is rotatably installed in the top cavity 5. A torsion block is arranged at the upper end of the torsion column 6. A bevel gear 7 is arranged at the bottom end of the torsion column 6. The conical gear ring 4 extends into the top cavity 5, and the bevel gear 7 and the conical gear ring 4 are meshed and connected. When connecting the pipes, the female connector 1 and the male connector 2 are docked, and then the torsion column 6 is rotated to drive the bevel gear 7 to rotate, and then the inner swivel ring 3 is driven to rotate through the conical gear ring 4. The inner swivel ring 3 and the first insertion section 201 are connected in cooperation so that the first insertion section 201 can be embedded in the first docking groove 101 and the second insertion section 202 can be embedded in the second docking groove 102, so that the female connector 1 and the male connector 2 can be docked, and the operation is very convenient.

[0029] The female connector 1 is provided with an inner cavity and a movable groove 12, in which an inner movable plate 9 is movably provided, a top column 10 is provided at one end of the inner movable plate 9, the right end of the top column 10 passes through the vertical section side wall of the first docking groove 101, and the other end of the inner movable plate 9 is connected to a first airbag 11; a second airbag 13 is provided in the movable groove 12, and the middle part of the second airbag 13 is fixed in the inner wall of the movable groove 12, and when the second airbag 13 is expanded, only the two sides are stretched, and the second airbag 13 and the first The airbags 11 are connected through an air pipe, a sliding top plate 14 is provided at one end of the second airbag 13, a tightening spring 15 is provided between the sliding top plate 14 and the left end of the movable groove 12, a sliding block 16 is provided at the other end of the second airbag 13, a shift block 19 is provided on the top of the sliding block 16, a connecting rod 17 is provided at the right end of the sliding block 16, the connecting rod 17 extends into the top cavity 5, a docking sleeve 18 is provided at the end of the connecting rod 17, and a fixing block 8 corresponding to the docking sleeve 18 is provided on the torsion column 6. The docking sleeve 18 is an arc-shaped structure, and a plurality of thorns are evenly arranged on the inner wall of the docking sleeve 18. The top of the thorns is sharp and inclined. A plurality of thorns are also arranged on the side wall of the fixed block 8, and the inclination direction of the thorns on the fixed block 8 is opposite to the inclination direction of the thorns on the docking sleeve 18, so that when the docking sleeve 18 is covered on the fixed block 8, the fixed block 8 can still rotate in one direction. Therefore, when the torsion column 6 is rotated when the female connector 1 and the male connector 2 are connected, the docking sleeve 18 will contact the fixed block 8, and the torsion column 6 will continue to be rotated to completely dock the female connector 1 and the male connector 2.

The end of the convex ring is a contracted structure and is embedded in the inner sealing groove 20. A plurality of inner flow holes 23 are evenly provided on the inner wall of the female connector 1, and the inner flow holes 23 are divided into horizontal sections and vertical sections. An extrusion plug 24 is connected to the left side wall of the movable sealing member 22, and the extrusion plug 24 is located in the horizontal section of the inner flow hole 23. When the equipment is in use, the fluid flow rate inside the pipeline is relatively high, and the internal fluid will enter the inner flow hole 23 and push the extrusion plug 24, thereby pushing the movable seal 22 to embed the convex ring into the inner sealing groove 20. Even if a tiny gap appears at the pipeline connection, the movable seal 22 will continue to be pushed into the inner sealing groove 20, which can greatly increase the sealing of the connection and prevent leakage.

[0031] In actual use, when connecting the female connector 1 and the male connector 2, the female connector 1 and the male connector 2 can be firmly connected because of the connection mechanism that is easy to fix. The operation is convenient and not easy to loosen. In addition, because of the fixed sealing ring, movable sealing mechanism and other structures, the sealing of the pipe connection can be greatly increased to prevent leakage at the pipe connection. When connecting the pipe, the female connector 1 and the male connector 2 are docked, and then the torsion column 6 is rotated to drive the bevel gear 7 to rotate, and then the inner rotating ring 3 is driven to rotate through the conical gear ring 4. The inner rotating ring 3 and the first insertion section 201 are connected in cooperation so that the first insertion section 201 is embedded in the first docking groove 101 and the second insertion section 202 is embedded in the second docking groove 102, so that the female connector 1 and the male connector 2 can be docked, and the operation is very convenient; when the female connector 1 and the male connector 2 are connected, the end of the first insertion section 201 pushes the top column 10 inward, so that the inner movable plate 9 squeezes the first airbag 11, and the gas inside the first airbag 11 enters the second airbag 13. In the process, the second airbag 13 expands and stretches to push the sliding block 16, so that the connecting rod 17 pushes the docking sleeve 18 to cover the fixed block 8, so that the fixed block 8 can be fixed, and the fixed block 8 cannot rotate in the opposite direction, thereby preventing the pipeline from loosening due to vibration; when the equipment is in use, the fluid flow rate inside the pipeline is relatively high, and the internal fluid will enter the inner flow hole 23 and push the extrusion plug 24, thereby causing the movable seal 22 to be pushed by the convex ring to embed into the inner sealing groove 20, even if a small gap appears at the pipeline connection, the movable seal 22 will continue to be pushed into the inner sealing groove 20, which can greatly increase the sealing of the connection and prevent leakage.
