Problems solved by technology
[0002] At present, in the field of water supply and drainage pipe fittings installation, PVC glue or hot melt is generally used for the installation of pipes. Since the pipe diameter of drainage pipe fittings is relatively large, it is difficult to ensure the horizontal and vertical pipes during installation, and the construction of glued PVC exists. The problem that it can no longer be adjusted after construction, the water supply and drainage pipe fittings are time-consuming and laborious to disassemble during construction, cannot be changed at one time, cannot be recycled and reused, and the problem of adjusting the direction and position of the pipeline

Embodiment Construction
[0012] The present invention will be further described below in conjunction with accompanying drawing:
[0013] Depend on figure 1 As shown, the easy-to-install quick socket pipe fitting includes a pipe fitting main body 4, and the socket of the pipe fitting main body 4 is provided with a limiting annular boss 5 and an annular shoulder 9 at intervals on the inner wall from the port inward, and the inner wall of the annular shoulder 9 is along the There are two annular grooves in the circumferential direction, and a sealing ring 7 is built in the annular groove. A group of symmetrical notches 8 are provided on the end surface of the annular shoulder 9. There is a pipe fitting main body 4 that cooperates with the pipe fitting main body 4 port and can connect the pipe fitting and the pipe material. The connected connecting sleeve 1, the lower part of the connecting sleeve 1 is the expansion claw 2, the expansion claw 2 is distributed in the circumferential direction, the outer wa...

The invention provides an easy-installation rapid-socket-spigot pipe fitting. The easy-installation rapid-socket-spigot pipe fitting comprises a pipe fitting main body, wherein a limiting annular boss and an annular shoulder are arranged in sequence at a certain interval on the inner wall which faces inwards from a port of the bell and spigot of the pipe fitting main body; the inner wall of the annular shoulder is provided with at least one annular groove along the circumferential direction; a sealing ring is embedded into the annular groove; the end face of the annular shoulder is provided with a group of symmetrical gaps; a connecting sleeve which is matched with the port of the pipe fitting main body and can be used for connecting the pipe fitting with a tubular product is arranged in the pipe fitting main body; expansion claws are arranged on the lower part of the connecting sleeve; the outer walls of the lower ends of the expansion claws are provided with limiting tables; fixing sheets are arranged on the inner walls of the lower ends of the expansion claws; small bosses are fixed at the lower ends of the two symmetrical expansion claws; the small bosses are matched with the gaps. The pipe fitting has the advantages of saving of time, labor force and materials during installation and detachment, good sealing effect, detachability, reusability, and stable pressure resistance.
