Referring to FIGS. 1-4, the present invention provides

A connector with a safety lock structure comprises an upper connector 1 and a lower connector 2, wherein bayonet lock connecting seats 3 are arranged on two sides of the upper connector 1, bolt hole sites 4 are respectively arranged on two sides of the lower connector 2, and a locking device 5 used for locking and limiting the bayonet lock connecting seats 3 to move is arranged on one side of each bolt hole site 4;

the structure principle is as follows:

when the safety double-lock connector is used, the upper connector 1 and the lower connector 2 are combined and electrically connected, at the moment, the locking device 5 is controlled to lock the bayonet pin connecting seat 3 inserted into the bayonet pin hole position 4, the purpose of safety double-lock is achieved, and connection looseness is prevented.

The upper connector 1 comprises an upper connecting seat 101, a plurality of pin holes 102 are formed in the upper connecting seat 101, and pin clamping seats 103 are arranged in the pin holes 102.

The lower connector 2 of the present invention is provided with a lower connecting seat 201, and the lower connecting seat 201 is provided with a plurality of pins 202 having the same number and position as the plurality of pin holes 102.

The bayonet lock connecting seat 3 comprises an inserting rod 301 arranged on the surface of the upper connector 1, and a limiting notch 302 is arranged on the inner wall of the inserting rod 301.

The bayonet lock connecting seat 3 is arranged in a downward extending mode.

The locking device 5 comprises a rotating seat 501 arranged on one side of a bolt hole position 4, a transverse sliding groove 502 is arranged between the bolt hole position 4 and the rotating seat 501, a transverse inserting rod 503 is movably arranged in the transverse sliding groove 502, a rotating disk 504 is rotatably arranged in the rotating seat 501, an eccentric shaft 505 is arranged on the rotating disk 504, a hinge seat 506 is arranged on the transverse inserting rod 503, and a connecting rod 507 is hinged between the hinge seat 506 and the eccentric shaft 505;

the structure principle is as follows:

the rotating disc 504 is manually rotated to drive the eccentric shaft 505 to rotate around the center of the rotating disc 504 in the rotating process, the connecting rod 507 is driven to pull or push the position of the hinge seat 506 in the process, and the transverse inserting rod 503 is inserted into or away from the transverse sliding groove 502, so that the purposes of locking and unlocking are achieved.
