Hot melting connecting device for building water flow pipeline

Abstract

The invention relates to the technical field of hot melting connection, and discloses a hot melting connection device for building water flow pipelines, which comprises a support frame and a hoop slidably mounted on the support frame, and further comprises a hot melting plate capable of sliding up and down at the top of the support frame, hinge rods are mounted on two sides in the hot melting plate, and sliders are hinged to the tops and bottoms of the hinge rods. One end of the sliding block is fixedly connected with a scraper, sliding grooves are formed in the surfaces of the two sides of the hot melting plate, the surface of one side of the scraper is tightly attached to the side surface of the hot melting plate, and a rotating plate is arranged on the outer side of the hot melting plate. The top of the scraping piece is in an arc shape and can be attached to the inner wall of the pipeline A. A connecting rod II moves back and forth to drive a bevel gear II and a bevel gear I to rotate in a meshed mode, so that a rotating plate and the scraping piece rotate at the same time, and then the top of the scraping piece makes contact with the inner wall of the pipeline A to scrape away hot melting plastic turning inwards. The pipe diameter of the pipeline A is prevented from being reduced, and the water pressure is not stable when water flows through the pipeline A.

Description

technical field [0001] The invention relates to the technical field of hot-melt connection, in particular to a hot-melt connection device for building water flow pipes. Background technique [0002] Hot melt connection refers to the connection between non-metal and non-metal. It is a connection method after heating to the (liquid) melting point. It is widely used in PP-R pipe, PB pipe, metal composite pipe, curved elastic vector aluminum alloy lining New pipes and fittings such as plastic composite piping systems are connected. [0003] When the hot-melt plastic pipe is used, the hot-melt plastic will turn inside and outside, and the inside-turned hot-melt plastic will reduce the diameter of the pipe, which will affect the water flow and cause unstable water pressure. There will also be blockages. SUMMARY OF THE INVENTION [0004] In view of the deficiencies of the above-mentioned background technology, the present invention provides a technical solution for a hot-melt c...

Problems solved by technology

[0003] In the case of hot-melt plastic pipes, the hot-melt plastic will turn outward and inward at the hot-melted part. The hot-melt plastic turned inside will reduce the diameter of the pipe, affecting the water flow and causing the water pressure to be unstable. The situation is serious. There will be a blockage
