A handheld PVC pipe parts polishing device

Abstract

The invention provides a handheld PVC (Polyvinyl Chloride) pipe fitting polishing device. The handheld PVC pipe fitting polishing device comprises a transmission blocking handle which is matched withan electric drill chuck, wherein a linkage rod is integrally arranged on the other side of the transmission blocking handle; the other side of the linkage rod is fixedly connected to a transmission mechanism which comprises a positioning plate and expansion links; the positioning plate and the expansion links are integrally arranged on the exterior of the linkage rod; the number of the expansion links is eight; each two of the expansion links serve as a group; and a positioning mechanism is arranged above each group of expansion links. After the pipe wall of a pipe fitting is fixed through a second limited plate and a first limited plate, a polishing groove is in contact with the pipe wall along with the deepening of the embedding depth of the pipeline on the positioning mechanism, and then the pipe wall is rotatably polished; and the handheld PVC pipe fitting polishing device is relatively convenient and simple to use.

Description

technical field [0001] The invention relates to the field of pipeline processing, in particular to a hand-held PVC pipe fitting grinding device. Background technique [0002] PVC is the abbreviation of (Polyvinylchlorid), the main component is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness and ductility. The top layer of this surface film is lacquer, and the main component in the middle is polyvinyl chloride. Vinyl chloride, the bottom layer is back-coated adhesive. [0003] It is a kind of synthetic material that is loved, popular and widely used in the world today. Its global usage ranks second among all kinds of synthetic materials. PVC-U pipe has strong corrosion resistance and is easy to bond. , low price, hard texture, but due to the leakage of PVC-U monomer and additives, it is only suitable for water supply systems with a delivery temperature not exceeding 45°C. Plastic pipes are used for drainage, waste water, chemicals...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a hand-held PVC pipe fitting grinding device to solve the problem that the existing grinding device generally requires workers to grind with sandpaper along the outer edge of the pipe, which is not convenient to operate, and it is time-consuming and laborious, and it is impossible to clean the grinding residue. collection, making the device less environmentally friendly
