Description

Quick reducing three-way joint of bellows open-type buckle Technical Field The utility model relates to the technical field of pipeline connection, in particular to a corrugated pipe opening type buckle quick-reducing three-way joint. Background In the fields of fluid transportation, cable protection and the like, the corrugated pipe is widely applied by virtue of good flexibility, deformation resistance and sealing performance. The performance of the corrugated pipe joint, which is a key component for realizing connection between corrugated pipes or connection between the corrugated pipes and other pipes, directly influences the stability and reliability of the whole pipeline system. When the prior corrugated pipe joint realizes variable diameter connection, a threaded or flange type structure is mostly adopted. The threaded joint is connected through screwing of threads, threads with different specifications are required to be matched in the connecting process of corrugated pipes with different pipe diameters, the installation operation is complex, the efficiency is low, the tightness is difficult to ensure in the reducing connection, the flange joint is firm in connection, the structure is complex, the cost is high, a large number of tools are required in the installing and dismantling processes, the time and the labor are consumed, and the requirements of quick installation and flexible reducing cannot be met. Therefore, there is a need for a bellows joint that can achieve quick diameter-changing connection, is easy to install and remove, and is reliable in sealing. Disclosure of utility model The utility model aims to provide a quick reducing three-way joint with an opening type buckle for corrugated pipes, which solves the problems of inconvenient assembly and disassembly, poor sealing performance, low efficiency and the like existing in the prior art when reducing connection is performed, and realizes quick and reliable connection between corrugated pipes with different pipe diameters. The utility model provides a bellows open-type buckle quick reducing three-way connection, includes, connects pipe A and reducing joint pipe B, connect pipe A's one end and bellows fixed connection, connect pipe A other end tip lateral wall to run through and be provided with a plurality of openings one, be provided with buckle one in the opening one, reducing joint pipe B includes, and body one end is provided with the separation blade, and the separation blade lower extreme is provided with the butt joint pipe, the butt joint pipe outer wall vertically arranges and is provided with a plurality of non return rings, the body upper end lateral wall runs through and is provided with a plurality of openings two, is provided with buckle two in the opening two. Preferably, a first limit stop is arranged on the inner wall of the joint pipe and below the opening. Preferably, the distance between the upper surface of the first limit stop and the orifice of the joint pipe a is L, and L is equal to the length of the joint pipe.
