Pipeline connecting device

Abstract

The invention discloses a pipeline connecting device which comprises a joint body, a plurality of elastic strips, a locking nut, a first stop part and a second stop part, wherein the joint body is provided with a channel; the elastic strips are circumferentially distributed at the port of the channel of the joint body; one end of each elastic strip is fixedly connected with the joint body; the elastic strips are used for clamping a pipeline inserted into the channel; the locking nut is provided with a first end close to the joint body and a second end opposite to the first end; a conical surface is formed on the inner wall of the second end; the inner diameter of the conical surface is gradually increased along the entering direction of the pipeline; the conical surface is matched with the outer walls of the elastic strips to clamp the pipeline; the first stop part is arranged on the outer wall of the joint body or the outer walls of the elastic strips; and the second stop part is arranged on the inner wall of the first end of the locking nut and is used for being matched with the first stop part to stop the locking nut from being separated from the joint body or the elastic strips.

Description

technical field [0001] The invention relates to a connection device, in particular to a pipeline connection device. Background technique [0002] Pipeline is an essential basic facility in industry, therefore, pipe connection device has become an indispensable device for pipes to be widely used. In order to connect two or more pipes together with high quality, two points are very critical: 1. The firmness of the connection between the pipes and the pipe connection device, and 2. The tightness of the connection between the pipes and the pipe connection device. The firmness of the connection and the tightness of the connection are determined by the connection relationship between the internal components of the pipe connection device. If the parts used to assemble the pipe connection device are not properly assembled, or the wrong parts are used for assembly, it is easy to loose the connection of the internal parts of the pipe connection device, and eventually it is likely to ...

AI Technical Summary

Problems solved by technology

If a variety of pipe connection devices with similar specifications are produced, this separate design will easily make the manufacturer use wrong parts when assembling the pipe connection devices, resulting in wrong assembly problems

This kind of problem is not easy to be found during assembly, but it is likely to cause the parts to loosen under force during use, which will eventually lead to poor sealing. as a result of

In addition, this separate design increases the number of parts, which not only makes the assembly work more complicated, but also increases the use of raw materials, resulting in an increase in production costs.
