Description
Technical Field
The utility model relates to a pipe joint technical field especially relates to a bellows joint.
Background
The corrugated pipe is a tubular elastic sensitive element formed by connecting foldable corrugated sheets along a folding and stretching direction, not only can be used as a fluid pipeline for conveying fluid, but also can be stretched due to the length, and is commonly used as a switching pipe of an electric appliance, two joints are generally connected at two ends of the corrugated pipe so as to be connected with equipment, at present, the most common mode of threaded connection is adopted, a port of the corrugated pipe is directly installed on the pipeline through a nut, the problems of weak connection, poor sealing performance and the like exist in the use process, the structure of a certain improved corrugated pipe joint is complex, time and trouble are consumed in installation and disassembly, in addition, a certain pressure exists in the inner part of the corrugated pipe under the working state, the inner wall of the corrugated pipe is extruded and stretched, and if the corrugated pipe is under the condition of overlarge pressure for a long time, the pressure on the inner wall of the corrugated pipe exceeds, the leakage phenomenon occurs, and serious potential safety hazards exist. Therefore, it is necessary to develop a bellows joint which is easy to install and remove, has good sealing performance, and can be freely stretched and elongated.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a corrugated pipe joint to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above purpose, the technical scheme of the utility model is as follows: the utility model provides a corrugated pipe joint, includes bellows, connector, overcoat core and sealing washer, the connector is equipped with the internal thread, just the internal periphery of connector one end is equipped with the protruding rank in location, the overcoat core is equipped with the external screw thread, the overcoat core with the connector passes through threaded connection, just the overcoat core with the one end that the connector is connected is equipped with the hem of turning up, the hem is used for the backstop the protruding rank in location of connector, the sealing washer is arranged in the surface of overcoat core hem with between the connector, the overcoat core other end is equipped with connecting slot, the bellows inserts connecting slot to connect through the riveting.
Preferably, the connector is a hexagon nut.
Preferably, the connector is made of stainless steel.
Compared with the prior art, the beneficial effects of the utility model reside in that: the utility model discloses simple structure, simple to operate is swift, and seals well nothing and leak, and the bellows passes through the riveting and is difficult for extracting in addition, and can bear powerful tensile. The corrugated pipe adopts polytetrafluoroethylene, and graphite, glass fiber and gallium indium tin alloy liquid metal are added as fillers, so that the wear resistance, toughness and elasticity of the corrugated pipe are improved, and the corrugated pipe can be freely stretched and elongated.
