At present, there are certain shortcomings in the use of existing water pipe installation and connection structures. They are generally installed by welding and threaded connection. However, the welded water pipes have a short service life and are inconvenient to install. The vibration and pressure generated when water is passed through can easily lead to rupture and leakage of the welding parts, resulting in a waste of water resources. Threaded connection also has the problem of inconvenient connection, which leads to low assembly efficiency and high processing cost, which does not meet the use requirements.

[0006] In the above-mentioned connecting pipe, both ends of the annular gasket are provided with L-shaped folded edges which enhance the sealing performance and have elasticity.

[0007] In the above-mentioned connecting pipe, annular grooves are provided on the outer peripheral walls of the water pipe and the connecting pipe body at the connecting end, and the two ends of the connecting shell are provided with convex ring parts protruding radially inward. The inner wall of the convex ring part is inclined and extends into the corresponding annular groove, and forms a seal by being assembled to contact the groove surface of the annular groove.

[0008] In the above-mentioned connecting pipe, the locking unit is composed of two connecting ears, a stud with a nut and a locking cap. The two connecting ears are respectively arranged on the corresponding connecting half shells and connected thereto. The connecting ears are provided with mounting holes for the stud to pass through and install. The locking cap is arranged on the outer end of the stud and connected thereto, and the locking cap is rotated.

[0009] Compared with the prior art, the connecting pipe has the following advantages:

[0010] 1. A connection unit is provided at the connection between the water pipe and the connection pipe body to facilitate the connection between the water pipe and the connection pipe body. The arrangement of the above structure improves the assembly efficiency and also ensures the sealing of the connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] like Figure 1 , Figure 2As shown, the connecting pipe comprises a connecting pipe body 1 and a water pipe 2. A connecting unit for facilitating the connection between the water pipe 2 and the connecting pipe body 1 is provided at the connection between the water pipe 2 and the connecting pipe body 1. The connecting unit consists of two connecting half shells 3 and an annular gasket 4. The annular gasket 4 is sleeved at the connection between the water pipe 2 and the connecting pipe body 1. The two connecting half shells 3 are spliced ​​to form a connecting shell that surrounds the annular gasket 4. The connecting shell is provided with two locking units at the splicing position. Both ends of the annular gasket 4 are provided with L-shaped folded edges 5 that enhance sealing and have elasticity. The L-shaped folded edges 5 are fitted with the corresponding water pipe 2 and the connecting pipe body 1 through the assembly of the above-mentioned connecting shell. Annular grooves 6 are provided on the outer peripheral walls of the water pipe 2 and the connecting pipe body 1 at the connection ends. Both ends of the connecting shell are provided with convex ring portions that protrude radially inward. The inner wall of the convex ring portion is inclined and extends into the corresponding annular groove 6, and is assembled with the annular groove 6. The groove surfaces are in contact with each other to form a seal, and a notch groove is provided on the inner wall of the convex ring part. A sealing ring mounted on the annular groove 6 can be provided at the notch groove. The cylinder is assembled and extruded to produce a sealing surface. An embedded groove is provided on the wall surface of the connecting pipe body 1 and the water pipe 2 located at the annular groove 6, so that the above-mentioned L-shaped folded edge 5 can be embedded and installed. Finally, the connection shell is assembled to fix the position of the annular gasket 4, and the sealing performance is also enhanced. The locking unit consists of two connecting ears 7, a stud 8 with a nut and a locking cap 9. The two connecting ears 7 are respectively arranged on the corresponding connecting half shells 3 and connected thereto. The connecting ears 7 are provided with mounting holes for the stud 8 to pass through and install. The locking cap 9 is arranged on the outer end of the stud 8 and connected thereto. By rotating the locking cap 9, the nut in the stud 8 conflicts with the corresponding connecting ear 7, and the locking cap 9 also conflicts with the corresponding connection. Weight reduction grooves can be provided on the opposite end surfaces of the two connecting ears 7.
