Detailed Description

The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1-4:

a locking type waterproof network connector comprises a connector 1 and sealing sleeves 2 on two sides of the connector 1, wherein the sealing sleeves 2 are in threaded sealing connection with the connector 1, grooves 211 are formed in the inner walls of the sealing sleeves 2, hollow columnar air bags 3 are embedded in the grooves 211, and a plurality of annular protrusions 31 are arranged on the inner walls of the air bags 3; the joint 1 is provided with a pressing structure pressing the air bag 3 on both sides thereof. Gasbag 3 suggests to adopt the natural latex material, its elasticity is the best, the nature is softer, be applicable to the material as the gasbag, increase sealing performance, in order to avoid compact structure damage gasbag, can be close to joint 1 one side pad clamping ring 212 at gasbag 3, the clamping ring adopts the hard metal material, utilize the clamping ring increase with the contact surface of gasbag, just so can reduce compact structure's area of contact and can not lead to the gasbag impaired, in order to further increase the leakproofness, the annular bulge 31 of gasbag 3 inner wall is continuous arc arch, the arc arch is when receiving inside atmospheric pressure oppression, become the face contact by the line contact, the threading of being convenient for, moreover, the deformability is good, sealed elasticity is bigger.

The sealing sleeve 2 is in threaded sealing connection with the joint 1, threaded sections 14 are arranged on two sides of the body 11 of the joint 1, the sealing sleeve 2 comprises a sleeve 21 and a threaded sleeve 22, a convex ring 213 with external threads is arranged on the outer edge of the tail end of the sleeve 21, and the threaded sleeve 22 is used for screwing the convex ring 213 with the threaded sections 14.

The pressing structure can be designed into a pressing section arranged at the tail end of the threaded section 14, the pressing section stretches into the groove 211 after the threaded sleeve 22 is screwed to press the air bag 3 tightly, so that the strength of the pressing section can be ensured, the pressing structure can also be composed of a plurality of independent columnar structures, but the structure is suggested to be matched with the pressing ring 212 for use due to the small contact area.

The sealing structure of the sealing sleeve 2 and the joint 1 can adopt a structure that a first sealing ring 4 is arranged between a threaded sleeve 22 and a convex ring 213, a second sealing ring 42 is arranged between the threaded sleeve 22 and the body 11, and a sealing gasket 41 is arranged between the sleeve 21 and the threaded section 14, which is a terminal sealing structure, or can adopt a rubber ring embedded in the side wall or outside the side wall for sealing.
