Description

Technical Field

[0001] The utility model belongs to the technical field of pipe joints, and in particular relates to a trachea quick joint. Background Art

[0002] A quick connector is a connector that can be used to quickly connect pipes. While achieving quick connection, the air tightness of the pipe connection must be ensured.

[0003] Although the quick connectors currently on the market are easy to install and quick to disassemble, at least six groups of clips are provided inside the female connector, each group of clips includes a slide groove arranged in the circumference of the female connector, in which a clip ball is placed. When not installed, the clip ball is located at one end of the slide groove close to the inside of the female connector under the push of a clip ring on the outside of the female connector. When the sub-connector needs to be inserted into the female connector, the clip ring is moved downward to release the moving space of the clip ball in the slide groove, and then the sub-connector is pressed into the female connector. At this time, the clip ball is inserted into the annular groove outside the sub-connector, and then the clip ring is released, so that the clip ring moves to the outer end of the slide groove under the elastic force of the spring, and the clip ball is stably fixed in the annular groove to complete the clipping of the letter connector.

[0004] In actual applications, the catch ball and the slide groove in the above structure are often damaged or worn, thus affecting the use. If any one of the positions is damaged, it will be difficult to open or close the device because the damaged position is internal. Utility Model Content
