Variable-diameter two-way pipe joint

Abstract

The invention belongs to the technical field of two-way pipe joints, and specifically belongs to a variable-diameter two-way pipe joint. The variable-diameter two-way pipe joint comprises a pipe body;the inner wall of the pipe body is provided with uniformly arranged annular grooves; cavities of the two annular grooves are each internally slidably connected with a first gear plate; the contrary sides of the two first gear plates are correspondingly provided with uniformly arranged arc-shaped grooves in the inner walls of the end faces of the first gear plates; and the inner wall of each arc-shaped groove is internally slidably connected with a slider. The variable-diameter two-way pipe joint provided by the invention is mainly for solving the problems that most of the existing two-way pipe joints cannot realize a diameter change function; in the prior art, a pipe and a pipe joint are generally fixed together by means of rings, hot melting, adhesion and the like; these locking ways cause unstability because the joint of the pipe joint and the pipe is a smooth surface, the pipe easily falls, or complete sealing cannot be realized after connection because the joint of the pipe jointand the pipe is uneven, quick dismounting cannot be realized after connection, and after dismounting the pipe and the pipe joint will be seriously damaged.

Description

technical field [0001] The invention belongs to the technical field of two-way pipe joints, in particular to a variable-diameter two-way pipe joint. Background technique [0002] The pipe joint is a connection tool between pipes and a detachable connection point between components and pipes. It plays an indispensable and important role in pipe fittings, and it is one of the two main components of hydraulic pipelines. Pipe joints are used for straight-line connections such as instruments, and the connection forms include socket welding or threaded connections. It is mainly used for small-diameter low-pressure pipelines, used for parts that need to be assembled and disassembled frequently, or used for final adjustment of pipelines using threaded pipe fittings. Related products are included in Kuaiyiyou. The structure should adopt metal surface contact sealing structure. The structure of gasket seal is usually used in general pipelines for conveying water, oil, air, etc., and...

AI Technical Summary

Problems solved by technology

[0006] In order to make up for the deficiencies of the prior art, the present invention proposes a variable diameter two-way pipe joint. The present invention is mainly used to solve the current two-way pipe joints. The pipe and pipe joint are fixed together by means of ring, hot melt, bonding, etc. These locking methods are not firm because the joint between the pipe joint and the pipe is a smooth surface, which may easily lead to the fall of the pipe, or the connection between the pipe joint and the pipe The unevenness of the joint makes it impossible to achieve complete sealing after connection, and it cannot be quickly disassembled after connection, which will cause serious damage to pipes and joints after disassembly
