Detailed Description

The invention will be further described with reference to examples in the drawings to which:

as shown in fig. 1 to 3, the present invention mainly includes a bottom plate 1, a self-priming rocker arm 2, a ratchet 3, a ski board 10, a pawl 11 and a stopper 12.

The bottom plate 1 is riveted with a ratchet shaft 4, the ratchet shaft 4 is rotatably connected with a ratchet 3 and a self-suction rocker arm 2, a ratchet return spring 5 is arranged between the ratchet 3 and the bottom plate 1, and the ratchet return spring 5 can enable the rotating ratchet 3 to return. The upper end of the self-priming rocker arm 2 is connected with the base plate 1 through a rocker return spring 13, a guide boss is arranged on the self-priming rocker arm 2, and the guide boss is connected in a guide slide rail 19 of the base plate 1 in a sliding manner.

The base plate 1 is riveted with a pawl shaft 6, the pawl shaft 6 is rotatably connected with a pawl 11, a pawl return spring 7 is arranged between the pawl 11 and the base plate 1, and the pawl return spring 7 can enable the rotating pawl 11 to return. The ratchet 3 and the pawl 11 are engaged with each other.

The apron closes on the 1 upper cover of bottom plate, rivets sleigh axle 8 on the apron, rotates on sleigh axle 8 and connects sleigh 10, is equipped with sleigh return spring 9 between sleigh 10 and the apron, and sleigh return spring 9 can let pivoted sleigh return.

A stop block 12 is arranged between the self-priming rocker arm 2 and the pawl 11, the stop block 12 is connected with a worm 14 through threads, and one end of the worm 14 is connected with a signal transmission motor. When the signal transmission motor works, the self-priming rocker arm 2 can rotate anticlockwise or the pawl 11 can rotate clockwise through the stop block 12.

The ratchet wheel 3 is provided with a first bulge 17, and the first bulge 17 presses the lower end of the ski board 10. The ratchet wheel 3 is provided with a second bulge 18, the bottom plate 1 is provided with a microswitch 15, and the second bulge 18 rotates anticlockwise and can contact the microswitch 15.

The pawl 11 is provided with a slot 20 for clamping the ski board 10, and the ski board 10 can be clamped into the slot 20 by clockwise rotation.

The working process of the invention is as follows: before the lock body is opened, the ratchet wheel presses the ski board through the first bulge under the action of the ratchet wheel return spring, and the pawl is meshed with the ratchet wheel 3 under the action of the pawl return spring, as shown in figure 1. When the lock body is opened, the lock catch presses the ratchet wheel to drive the ratchet wheel to rotate anticlockwise, so that the sled plate is gradually released. As shown in fig. 2, when the latch is in the half-lock position, the second protrusion of the ratchet wheel contacts the microswitch, the microswitch controls the signal transmission motor to drive the worm to rotate, the worm drives the stop block to push the self-priming rocker arm to pull the ratchet wheel to the full-lock position, and at the moment, the ski board moves clockwise to contact the upper end face of the pawl. Then, the signal transmission motor drives the stop block to push the pawl to rotate clockwise, so that the ratchet wheel and the pawl are disengaged, the ski board is clamped into the clamping groove of the pawl under the action of the ski board return spring to prevent the pawl from returning, the ratchet wheel moves clockwise under the action of the ratchet wheel return spring to push out the lock catch, the first bulge of the ratchet wheel pushes the ski board to enable the ski board to be disengaged from the pawl, and the ratchet wheel and the pawl return to a full-open state.
