Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

As shown in fig. 1 to 5, a plug-in pipe fitting belongs to a plug-in assembled water supply pipe assembly, and comprises a joint main body 1, a pipe fitting assembly 2 and a sealing retainer ring 3; a plurality of inner grooves 101 are uniformly distributed on the inner wall of the through hole 102 of the joint main body 1; a plurality of sawtooth water retaining rings 301 are uniformly distributed on the inner circumference of the sealing retainer ring 3 in parallel, the sealing retainer ring 3 is arranged in the inner groove 101 of the joint main body 1 and is elastically attached and connected, and the arc angles of the sawtooth water retaining rings 301 face the axial middle position of the joint main body 1; pipe fitting subassembly 2 contains pipe fitting main part 201, fixed end face seal 4 is connected to the terminal surface of pipe fitting main part 201, and bayonet installation respectively of two pipe fitting subassemblies 2 is in connecting main part 1, and the terminal surface elasticity laminating of two end face seal 4, the pipe fitting subassembly 2 terminal surface leakage of prevention butt joint to axial deformation's hidden danger in the time of can the elastic buffer installation or in the use, the outer periphery wall of laminating pipe fitting main part 201 is wrapped up to sawtooth manger plate circle 301 elasticity, and the radial leakage of intraductal water of the effectual avoidance of oblique sawtooth manger plate circle 301, the utility model discloses draw out formula structure, dismouting simple and convenient, and need not to borrow the manual dismouting of specialized tool, the water pipe that is fit for the temporary location.
