detailed description

Example 1

As shown in Figures 1-4, a quick-plug connector includes a sleeve 1 and a housing 2, the sleeve 1 is provided with an L-shaped slot 3, and the housing 2 is equipped with a fixing pin 4. The fixed pin 4 is connected with the L-shaped slot 3; a joint 5 is installed in the sleeve 1, and a base 6 is installed on the joint 5, and the base 6 is connected with an arc-shaped ejector rod 8 with a spring 7; A cap body 9 is also installed in the casing 1, and an easy-to-twist groove 10 is provided on the cap body 9; a second base 11 is installed in the housing 2, and the second base 11 is connected with the second spring 12 The second arc push rod 13 is connected; the housing 2 is also equipped with a second cap body 14, and the second cap body 14 is provided with a second easy-to-twist groove 15; after the casing and the housing are installed, The arc-shaped ejector pin 8 and the second arc-shaped ejector pin 13 withstand each other, so that a gap is formed between the arc-shaped ejector pin 8 and the cap body 9, and a gap is formed between the second arc-shaped ejector pin 13 and the second cap body 14, The two form a flow channel for water; when the two are separated, they are in a sealed state.

The outer surface of the sleeve 1 is provided with knurling 16 to increase friction and facilitate the connection between the sleeve and the housing.

A sealing ring 17 is installed on the housing 2; a rubber ring 18 is installed between the joint 5 and the casing 1, and both the sealing ring and the rubber ring play a sealing role.

The quick-plug connector of this embodiment has an exquisite structure, is convenient to manufacture and disassemble, and has the characteristics of high sealing.
