DETAILED DESCRIPTION

[0019] The technical scheme in the utility model embodiment will be clearly and completely described in combination with the drawings in the utility model embodiment.

[0020] The utility model provides technical scheme: as Figures 1 to 4As shown in this embodiment, a coaxial connector with a sealed structure includes a coaxial connector, which includes a connecting end 1 and an access end 2. A rubber ring 3 is fixedly installed on the outer ring of the connecting end 1, and the rubber ring 3 and the outer ring of the connecting end 1 form a socket 4. The access end 2 is inserted into the interior of the socket 4.

A connecting block 8 is fixedly installed in a ring array around the central axis of the rotating ring 7 at one end. An extrusion rod 9 is installed at the end of the connecting block 8. An extrusion ring 10 is slidably installed in a ring array around the central axis of the connecting end 1 at the position corresponding to the position of the rubber ring 3. Several extrusion rings 10 form a circle. An extrusion inclined surface 11 is opened on the outer ring of the extrusion ring 10. The extrusion rod 9 is in extrusion contact with the extrusion inclined surface 11. A positioning hole 12 is opened on the extrusion ring 10 at the position corresponding to the position of the extrusion inclined surface 11. The positioning hole 12 is slidably inserted into the extrusion rod 9.

[0024] Insert the access end 2 into the socket 4. The rubber ring 3 can wrap around the outside of the access end 2. By rotating the rotating ring 7, the extrusion rod 9 installed on the connecting block 8 will extrude the extrusion ring 10, which can drive the extrusion ring 10 to slide along the trajectory of the limiting rod 15. The extrusion rod 9 extrudes the extrusion slope 11 on the extrusion ring 10 until the extrusion rod 9 is inserted into the positioning hole 12, which can fix the position of the rotating ring 7. Several extrusion rings 10 can be arranged into a circle. The extrusion ring 10 can extrude the rubber ring 3 to ensure a seal between the rubber ring 3 and the access end 2 at a certain length, thereby improving the sealing effect. At the same time, when the extrusion ring 10 extrudes the rubber ring 3, the inner ring of the rubber ring 3 will also be extruded against the outer surface of the access end 2. Through the friction between the rubber ring 3 and the access end 2, the friction fixation between the connecting end 1 and the access end 2 can be facilitated.

[0026] When installing between the connecting end 1 and the access end 2, the extrusion rod 9 will be extruded by the extrusion ring 10 and slide inside the sliding hole 13, at this time the extrusion spring 14 is in the elongated state, when the extrusion rod 9 moves to the positioning hole 12, the extrusion rod 9 can be inserted into the positioning hole 12 by the pulling of the extrusion spring 14, for fixing the position of the rotating ring 7.

[0027] As shown in Figures 1 to 4 The outer ring of the connecting end 1 is arranged in an annular array around the central axis of the connecting end 1 near the rotating ring 7, and a limiting rod 15 is arranged at the position corresponding to the limiting hole 16 of the extrusion ring 10.

[0028] The limiting rod 15 can support and limit the movement of the extrusion ring 10.

[0029] As shown in Figures 1 to 4 The rubber long ring 3 and the positioning ring 5 are fixedly connected by heat melting, and the rubber long ring 3 and the connecting end 1 are fixedly connected by heat melting.
