Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding of the skilled person.

As shown in fig. 1 to 4, the self-locking sealing crimping device applied to the separable connector comprises two fixing rings 4 arranged oppositely and a clamping member arranged between the two fixing rings 4.

The two fixing rings 4 are fixed by rivets 7. Two opposite faces of the two fixing rings 4 are oppositely provided with symmetrical guide grooves 5, and the guide grooves 5 are obliquely arranged and are distributed in a circumferential array manner along the fixing rings 4. The guide groove 5 is obliquely arranged to provide a sliding track for tightening or loosening the chucking member.

The clamping piece comprises a driving shaft 1, a driving plate 2, a clamping arc plate 3, a linkage plate 6 and a connecting rod 8. Both ends of the driving shaft 1 are fixed between the two fixing rings 4, and the connecting rods 8 are slidably disposed between the guide grooves 5 facing each other. The head parts of the 4 clamping arc plates 3 are connected with a connecting rod 8 in a shaft mode, the tail parts of the 4 clamping arc plates are arranged on the outer ring of the connecting rod 8 in a blocking mode, a circle is formed by the clamping arc plates 3 in a surrounding mode, and the clamping arc plates 3 are clamped or loosened with the front connector and the outgoing line side sleeve through the sliding of the connecting rod 8 along the guide groove 5. The tail part of the clamping arc plate 3 is not fixed and is arranged on the outer ring of the connecting rod 8 in a blocking mode, and when the head part slides, the free structure of the tail part provides a movement space for clamping or loosening between the clamping arc plates 3 and the front joint and the wire outlet side sleeve.

The middle part of one of the clamping arc plates 3 is provided with a transmission hole 9 used for being hinged with the driving plate, one end of the driving plate 2 is connected with the driving shaft 1, and the other end of the driving plate is hinged with the clamping arc plate 3 provided with the transmission hole 9. The linkage plate 6 is provided with 3, and the head and the tail of the linkage plate are rotatably connected through a connecting rod 8. When rotating drive shaft 1, drive shaft 1 drives drive plate 2, and drive plate 2 drives the tight arc plate 3 motion of clamp that is equipped with transmission hole 9, and the motion interlock board 6 motion of the tight arc plate 3 of clamp that is equipped with transmission hole 9, the motion of connecting plate 6 drive connecting rod 8 along the motion of guide way 5, and the motion of connecting rod 8 drives other three tight arc plate 3 motions of clamp, and then realizes pressing from both sides between the tight arc plate 3 with front connector and play line side sleeve pipe chucking or loosen.
