Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 2, the present embodiment provides a fluid connector including: socket 2 and with socket 2 threaded connection's plug 1, plug 1 is provided with toper locking ring 3 on being located the outer lane in socket 2, is provided with the hollow frustum 4 that is suitable for with toper locking ring 3 sticiss on the inner circle of socket 2. In the process that the plug 1 is gradually screwed into the socket 2, the hollow frustum 4 applies more and more pressure to the tapered locking ring 3, so that the rear end of the socket 2 is fixedly and hermetically connected with the front end of the plug 1.

Specifically, in this embodiment, the lateral wall of plug 1 is fitted with a contraceptive ring and is equipped with recess 11, two terminal surfaces of toper check ring 3 respectively with two lateral walls butts of recess 11, recess 11 realizes compressing tightly toper check ring 3 for toper check ring 3 is difficult for axial displacement, thereby makes things convenient for cavity frustum 4 to exert pressure to toper check ring 3.

Specifically, in this embodiment, the inner wall of the tapered locking ring 3 is provided with a line 32 for increasing the groove bottom friction force between the tapered locking ring 3 and the groove 11. The shape of ridges 32 may be, but is not limited to, a grid of depressions.

Specifically, in this embodiment, the tapered locking ring 3 is provided with the notch 31, so that the resistance of the hollow frustum 4 to the tapered locking ring 3 when applying pressure is greatly reduced.

In the present embodiment, the rear end of the hollow frustum 4 is extended outward with a hollow cylinder 6. The plug 1 is sleeved with a threaded sleeve 62 which is in threaded connection with the hollow cylinder 6. After the hollow frustum 4 compresses the tapered locking ring 3, the threaded sleeve 62 is screwed into the hollow cylinder 6, so that the connection firmness between the plug 1 and the socket 2 is further improved.

In this embodiment, an annular groove 61 is formed in the inner ring of the hollow cylinder 6, and a water-swelling sealing rod 7 is disposed in the annular groove 61. When the liquid in the fluid connector flows into the joint between the plug 1 and the socket 2, the water-swelling seal rod 7 can prevent the liquid from leaking outwards, so that the sealing performance of the fluid connector is improved.

Specifically, in the present embodiment, the outer ring of the plug 1 is connected with the first connecting sleeve 8 by screw threads; the outer ring of the socket 2 is in threaded connection with a second connecting sleeve 9; the outer wall of the first connecting sleeve 8 and the outer wall of the second connecting sleeve 9 are respectively provided with threads suitable for being connected with external equipment.

In conclusion, in the process that the fluid connector plug 1 is gradually screwed into the socket 2, the pressure applied to the tapered locking ring 3 by the hollow frustum 4 is increased, so that the socket 2 and the plug 1 are attached more tightly and firmly, and the leakage is reduced; the groove 61 enables the conical locking ring 3 not to move axially easily, so that the hollow frustum 4 can apply pressure to the conical locking ring 3 conveniently; the notch 31 greatly reduces the resistance when the hollow frustum 4 applies pressure to the tapered locking ring 3; the hollow cylinder 6 is in threaded connection with the outer ring of the plug 1, so that the connection firmness between the plug 1 and the socket 2 is further improved; the water-swelling water stop strip 7 can prevent liquid from leaking outwards, and the sealing performance of the fluid connector is improved; the first connecting sleeve 8 and the second connecting sleeve 9 facilitate the plug 1 and the socket 2 of the fluid connector to be firmly connected with external equipment.

All the parts of the devices selected in the present application are general standard parts or parts known to those skilled in the art, and the structures and principles thereof can be known to those skilled in the art through technical manuals or through routine experimental methods.
