In a further technical scheme, a convex pipe is arranged on one end, far away from the first connecting part, of the second connecting part in an axially extending mode along the through hole, an annular groove is formed in the circumferential side face of the convex pipe, and a hook body extending into the annular groove is arranged on the sealing gasket; this cooperation through coupler body and annular groove, the seal gasket after moulding plastics can set up on the second connecting portion firmly, can not appear droing.
In a further technical scheme, the circumference outside of first connecting portion is equipped with a plurality of annular protruding muscle, annular protruding muscle is used for increasing the frictional resistance between first connecting portion and the body.
In a further technical scheme, an annular cutting groove is formed in the circumferential side face of the second connecting part, an expansion ring is arranged in the annular cutting groove, and a notch is formed in the expansion ring; an annular clamping groove for the expansion ring to extend into is formed in the threaded sleeve; this setting realizes the rotation of thread bush and second connecting portion through the expand ring and connects.
In a further technical scheme, the thread sleeve comprises an internal thread section, and a conical surface is arranged on the inner side of one end, far away from the internal thread section, of the thread sleeve; the arrangement realizes that the hose connector is connected on a pipeline through the internal thread section in the threaded sleeve; the arrangement enables the expansion ring to automatically contract under the action of the conical surface when the second connecting part is inserted into the threaded sleeve, so that the threaded sleeve can be conveniently installed on the second connecting part.
In a further technical scheme, anti-skid threads are arranged on the circumferential side surface of the threaded sleeve; the friction resistance when setting up anti-skidding line can increase rotatory thread bush.
(III) advantageous effects
Compared with the prior art, the technical scheme of the utility model have following advantage:
the sealing gasket made of plastic is injected on the end part of the second connecting part, and the sealing gasket after injection molding can be firmly arranged on the second connecting part and cannot fall off through the matching of the hook body on the sealing gasket and the annular groove on the second connecting part, so that the phenomenon of water leakage at the connecting part of the hose connector is ensured not to occur; in addition, the sealing gasket is integrally formed on the second connecting part in an injection molding mode, and compared with the traditional mode that the sealing gasket is manually or automatically buckled and pressed, the sealing gasket never falls off. (there is a risk of separation of any snap-fit mechanical structures).
