[0004] A kind of aviation lifesaving seat shoulder strap connecting buckle dismounting device, including fixed platform matched with shoulder strap connecting buckle, fixed screw one matched with side end position of fixed platform, limiting hole and fixed hole arranged on fixed platform, limiting rod matched with limiting hole, dismounting wrench for dismounting fixed screw two on shoulder strap connecting buckle.

[0005] As a further improvement of the present application, the fixed platform is provided with a groove matching the size of the shoulder strap connecting buckle.

[0006] As a further improvement of the present application, the fixed platform is further provided with a dismounting hole matched with the dismounting wrench.

[0007] As a further improvement of the present application, the dismounting hole is arranged on the inner wall of the groove.

[0008] As a further improvement of the present application, the fixed screw one is provided with a knife edge matching the fixed shaft pin of the shoulder strap connecting buckle.

[0009] As a further improvement of the present application, the knife edge has a clockwise thread.

[0010] As a further improvement of the present application, the dismounting wrench is a T-shaped wrench.

[0011] As another improvement of the present application, a dismounting method of aviation lifesaving seat shoulder strap connecting buckle dismounting device is provided, and the specific steps are as follows:

[0012] S1, the fixed shoulder strap connecting buckle: when the fixed shaft pin needs to be disassembled from the shoulder strap connecting buckle, only one person needs to put the shoulder strap connecting buckle into the groove of the fixed platform, install the fixed screw one and the limiting rod, and fix the shoulder strap connecting buckle;

[0013] S2, disassemble the fixed screw two: use the disassembly wrench to unscrew the fixed screw two of the shoulder strap connecting buckle through the disassembly hole;

[0014] S3, fixed limiting rod: the limiting rod prevents the shoulder strap connecting buckle from rotating in the groove after installation, and the disassembly wrench prevents the disassembly wrench from slipping off and causing personal injury when disassembling the fixed screw two of the shoulder strap connecting buckle through the disassembly hole.

[0015] The beneficial effects of the present application are: considering the shape and function of the fixed shaft pin, without changing the fixed shaft pin and the connecting buckle, the use is safer and the use is better through the additional device; after the improvement of the present application, the number of operating personnel can be reduced, the operation mode during disassembly can be improved, and a single person can easily complete the disassembly operation of the shoulder strap connecting buckle.
