Detailed Description

In order to describe the technical content, the constructional features, the achieved objects and effects of the present utility model in detail, the following description is made in connection with the embodiments and the accompanying drawings.

Referring to fig. 1 and 2, a movable clamping portion 2 of the present utility model is inserted into a joint portion 1, an outer end of the movable clamping portion 2 is a pressing portion 21 with a diameter larger than an inner diameter of the joint portion, an inner end of the movable clamping portion 2 is a plurality of elastic pawls 22, a pawl head accommodating cavity 11 of an elastic pawl head 223 is provided in the joint portion 1, a front end of the pawl head accommodating cavity 11 is a pawl inclined back pressing tip 12, the pawl inclined back pressing tip 12 presses against a pawl inclined back 222 of the elastic pawl head 223, a rear end of the pawl head accommodating cavity 11 is a pawl head tip pressing inclined surface 13, the pawl head tip of the elastic pawl head 223 presses against the inclined surface, and a pawl inner protrusion 221 for clamping a hard pipe is provided inside the elastic pawl head 223.

When the pipe is used, the hard pipe is inserted into the joint part 1, the pawl inner protruding thorns 221 clamp the hard pipe, and when the pipe is pulled outwards, the pawl inclined back propping point 12 props against the pawl inclined back 222 to enable the pawl head to be clasped inwards, so that the pipe cannot be separated. When the pipeline is to be dismounted, the extrusion part 21 of the movable clamping part 2 is pressed inwards by force, the elastic pawl head 223 is outwards opened under the action of the pressing inclined surface 13 of the tip end of the pawl head, the clamping of the elastic pawl 22 on the pipeline disappears, and the pipeline can be pulled out.

For sealing, sealing rings 31, 33, 32 are arranged between the hard tube and the movable clamping part, between the hard tube and the joint part and between the movable clamping part and the joint part.

The quick-connect connector can be used for straight connectors, elbows, tee connectors and the like, and can be used for one end or a plurality of ends in the connectors.

The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent shapes or structural changes made by the present utility model and the accompanying drawings, or direct or indirect application in other related technical fields, are included in the scope of the present utility model.
