Detailed description of the invention
Below in conjunction with the accompanying drawings, by specific embodiment, the technical solution of the utility model is carried out clear,
Complete description.
This utility model embodiment provides a kind of joint (see accompanying drawing 1,2), including: public hollow cylinder 1 He
Female hollow cylinder 2, described public hollow cylinder 1 one end is interface 11, and the other end is bayonet socket 12；Described mother
Hollow cylinder 2 one end is socket 21, and the other end is cell body 22；Described bayonet socket 12 inserts in cell body 22,
The lateral wall of described interface 11 has the first annular groove 13 for installing snap ring 3, and is used for installing sealing
Second annular groove 14 of circle 4, the medial wall of described female hollow cylinder 1 has relative with described first annular groove 13
First annular groove 23.Built-in first annular groove the 13, second annular groove 14 of this utility model and with the first ring
