Description

PVC water supply pipe connecting assembly Technical Field The utility model relates to the technical field of PVC water supply pipe connection, in particular to a PVC water supply pipe connection assembly. Background The PVC water supply pipe is a water supply pipe which is produced by taking sanitary polyvinyl chloride resin as a main raw material, adding quantitative stabilizer, lubricant, filler, color enhancer and the like, extruding and molding by a plastic extruder, performing injection molding by an injection molding machine, and performing the procedures of cooling, solidifying, shaping, checking, packaging and the like. The utility model provides a PVC water supply pipe coupling assembling that current bulletin number is CN220506130U discloses, relates to water piping connection spare technical field, including two body and a plurality of spring, two the same adapter sleeve has been cup jointed jointly to the relative one end of body, the adapter sleeve is provided with fixed cover with the other end of body, the notch has been seted up in the outside of adapter sleeve, fixedly connected with lag in the cell wall of notch, the endotheca has been cup jointed to the inboard of lag, be provided with a plurality of shock attenuation spare between endotheca and the adapter sleeve, the spring sets up in the inside of shock attenuation spare, two the outside of fixed cover has all been cup jointed the edge cover, the edge cover is connected with the body outside through the seal glue layer, the size of lag with the size phase-match of notch. The protection structure outside the connecting component is added, the spring structure in the connecting component is protected, and the using effect of the connecting component is improved. The prior art increases the spring structure and is used for improving the protective effect of coupling assembling, but the life of spring is limited, so the effect that adopts the spring is relatively poor, for this reason, we propose a PVC feed pipe coupling assembling. Disclosure of utility model The utility model aims to provide a PVC water supply pipe connecting assembly, which solves the problems in the prior art.
