Abstract

The invention relates to PVC (polyvinyl chloride), in particular to an internal opening type cut-off device for mounting a PVC water supply pipeline, which comprises a special-shaped bottom plate, a mounting plate, a ratchet wheel clamping assembly, a circle center clamping assembly, an internal opening assembly and the like, a mounting plate is fixedly connected to the special-shaped bottom plate, a ratchet wheel clamping assembly is rotatably connected to the mounting plate, a circle center clamping assembly is fixedly connected to the mounting plate, and an internal opening assembly is fixedly connected to the mounting plate. The clamping rack drives the arc-shaped clamping plate to move so as to fix the PVC water supply pipeline and devices on the PVC water supply pipeline, meanwhile, the grooving rotating disc drives the rotating round rod and the opening arc-shaped plate to move, and then the opening arc-shaped plate clamps the PVC water supply pipeline placed in the opening arc-shaped plate, so that the PVC water supply pipeline is clamped and fixed, the PVC water supply pipeline is conveniently cut, and the cutting efficiency is improved. And subsequent operation is facilitated.

Description

technical field [0001] The invention relates to a PVC, in particular to an internal expansion type cutting device for PVC water supply pipeline installation. Background technique [0002] PVC water supply pipe is made of sanitary polyvinyl chloride resin as the main raw material, adding quantitative stabilizers, lubricants, fillers, color enhancers, etc., extruded by plastic extruder and injection molded by injection molding machine, through cooling, curing, A kind of water supply pipe produced by shaping, testing, packaging and other processes. PVC water supply pipe has good pressure resistance, impact resistance and tensile strength performance. At the same time, it has the characteristics of quick and easy pipeline connection construction and low construction engineering cost. . [0003] The existing device is to directly cut off the PVC water supply pipe. The shape of the PVC water supply pipe is a round pipe, and the impact resistance of the material is relatively toug...
