Detailed Description

The following is only the preferred embodiment of the present invention, the protection scope is not limited to this embodiment, and all technical solutions belonging to the idea of the present invention should belong to the protection scope of the present invention. It should also be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and such modifications and decorations should also be regarded as the protection scope of the present invention.

As shown in fig. 1, a novel quick coupling comprises a male coupling component, a female coupling component and a union nut 1, wherein one end of the male coupling component and one end of the female coupling component can be connected through the union nut 1, so that a user can install the quick coupling into an air conditioner component conveniently.

The male connector assembly consists of a male connector body 2, the ejector pin 3 and a spring a4, and the ejector pin 3 forms a hard sealing effect in the male connector body 2 under the elastic force action of the spring a4, so that the sealing performance of the male connector assembly can be improved, and the function of preventing media from flowing back is also achieved. The female joint assembly consists of a female joint body 5, a valve core 6, an inner sleeve 7 and a spring b8, wherein a snap ring c14 is arranged between the outer side of the inner sleeve 7 and the inner side of the female joint body 5, and the snap ring is arranged between the inner sleeve 7 and the female joint body 5, so that the inner sleeve 7 and the female joint body 5 can be connected. The valve core 6 and the inner sleeve 7 form a hard seal in the female joint body 5 through the elastic force action of the spring b8, so that the sealing performance of the female joint assembly is improved.

A sealing ring a9 is arranged between one side of the inner sleeve 7 and one side of the female joint, and one side of the inner sleeve 7 and one side of the female joint form soft sealing through a sealing ring a9, the sealing ring a9 can increase the sealing performance between one side of the inner sleeve 7 and one side of the female joint, and therefore the sealing performance of the female joint assembly is guaranteed. Two sealing rings b10 are arranged between the other side of the inner sleeve 7 and one side of the valve core 6, soft sealing is formed between the other side of the inner sleeve 7 and one side of the valve core 6 through two sealing rings b10, and the two sealing rings b10 increase the sealing performance between the other side of the inner sleeve 7 and one side of the valve core 6, so that the sealing performance of the male joint component is ensured, and the overall sealing performance of the quick joint is increased through the sealing effect of the sealing ring a9 and the two sealing rings b 10.
