Connecting and fixing auxiliary mechanism for threaded pipe connector

Abstract

The invention provides a connecting and fixing auxiliary mechanism for a threaded pipe connector. The connecting and fixing auxiliary mechanism comprises a main body, threaded pipe bodies are arrangedon the left side and the right side of the main body, a fixing part is arranged in the main body, a spring mechanism is arranged on the inner wall of the fixing part, a movable part is fixedly connected to the shaft end of the spring mechanism, a first gear rack is arranged on each of the upper side and the lower side of the movable part, the first gear racks are connected with first movable gears in a meshing mode, and the sides, away from the first gear racks, of the first movable gears are connected with second gear racks in a meshing mode. According to the connecting and fixing auxiliarymechanism for the threaded pipe connector, connection is easy, fast and reliable, time and labor are saved, in addition, the connecting position can be effectively prevented from being rusted, the device has good stability, meanwhile, the working intensity and the working difficulty of people are lowered, the time and labor are saved, and the practicability of the device is improved.

Description

technical field [0001] The invention belongs to the technical field of threaded pipes, in particular to a connection and fixing auxiliary mechanism for threaded pipe joints. Background technique [0002] Threaded pipe, also known as low-rib pipe, is mainly used to expand the heat transfer area by ribbing the outside of the pipe. It is generally used in occasions where the heat transfer coefficient inside the pipe is more than twice that of the heat transfer coefficient outside the pipe. For condensation and boiling outside the pipe, due to surface tension It also has a good strengthening effect. The threaded pipe works in harsh environments such as high temperature, high pressure, and corrosive gas for a long time, and has high requirements for its corrosion resistance and stability. At the same time, the difficulty of production methods and processing technology is taken into account. To a certain extent, copper and aluminum are usually selected as the material of the threa...

Problems solved by technology

[0003] With the continuous development of society and the continuous advancement of science, the application of threaded pipes has become more and more extensive, and threaded pipes basically meet people's needs during use, but there are still some problems. The traditional threaded pipe connection The method is usually to manually fix the two threaded pipes, and then perform spot welding, which not only increases the labor intensity of the workers, but also affects the quality of the later product of the threaded pipes, and is fixed by welding, which is inconvenient to disassemble. Moreover, the traditional connection method is easy to expose it to the air, which is easy to cause corrosion, make the pipeline loose, and make the device less stable, so there are deficiencies
