Connector and connecting pipe movable connection structure, connecting process and assembling tool thereof

Abstract

The invention provides a connector and connecting pipe movable connection structure, a connecting process and an assembling tool thereof, belongs to the technical field of machinery, and solves the problems of easy corrosion and easy blockage of the conventional connector and connecting pipe movable connection structure for a long time. The connector and connecting pipe movable connection structure comprises a connector and a connecting pipe, wherein an inner wall of the connector is provided with an inner recess; the front end of the connecting pipe is inserted into the connector and an outer wall of the front end of the connecting pipe is provided with an outer recess which is positioned on the connector; the connecting pipe is provided with a stopper part which can prevent the connector from axially moving backwards along the connecting pipe when the front end of the connecting pipe is positioned in the connector; and a snap ring which can prevent the connector from axially forwards separating from the connecting pipe along the connecting pipe and enable the connector and the connecting pipe to be movably connected in a circumferential direction is arranged between the inner recess and the outer recess. The connector and connecting pipe movable connection structure has the advantages of long service life, easy manufacturing, easy implementation, simple processing steps, convenient movable connection and the like.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to the mechanical connection of pipelines, in particular to a flexible connection structure of a joint and a connecting pipe, a connection process thereof and an assembly tool. Especially suitable for the connection of hydraulic and pneumatic pipeline components. Background technique [0002] In daily production and life, two objects are often connected in the form of an active connection. For example, threaded connections are often used in hydraulic and pneumatic pipeline connections, in which the nut and the pipe body are in the form of flexible connections. The active connection forms are now commonly used with buckle type, sleeve type and perforated steel wire, etc., and they all have their own advantages and disadvantages. [0003] The crimping type is suitable for parts with small heads and big tails; but it needs a machine to carry out, and the tension force is not strong w...

Problems solved by technology

Obviously, the U-shaped positioning card in the above scheme needs to be shrunk slightly before it can be inserted. After being installed, the U-shaped positioning card is stuck due to elastic expansion, and it can be taken out after it needs to be shrunk. Will corrode, or get stuck due to external ingress of ashes, dross, etc.
