Embodiment
Accompanying drawing being given for example only property explanation, it is impossible to be interpreted as the limitation to this patent；
In order to more preferably illustrate the present embodiment, some parts of accompanying drawing have omission, zoomed in or out, and do not represent actual product
Size；
To those skilled in the art, it is to be appreciated that some known features and its explanation, which may be omitted, in accompanying drawing
's.
The technical solution of the utility model is described further with reference to the accompanying drawings and examples.
Embodiment 1
As shown in Figure 1-2, a kind of telescopic joint with locating snap ring, including telescopic joint main body 1, sealing ring 2 and gland 3, institute
It is hollow tubular structure to state telescopic joint main body 1, and its one end is holds downstream, and the other end is end facing water, and the telescopic joint main body 1 is
Integrated injection forming structure, it includes portion 11 downstream and the portion 12 that meets water, and the internal diameter in portion 11 and external diameter are all higher than the portion of meeting water downstream
