The side walls of the housing 1 are fixedly connected.

It can be seen from the above that the elastic member 10 is designed as the elastic ring 18, which can directly allow the straight shaft 5 to pass through the cavity, and can fully exert the elastic restoring force while making the mechanical rotation structure more compact.

Further, the roller 4, the fixed wheel 7, the positioning part 9 and the magnetic metal part 8 are all made of die-casting aluminum alloy.

Another technical scheme provided by the present invention is:

A lock, comprising a lock body and the above-mentioned mechanical rotation structure; the lock body is provided with a groove portion, the mechanical rotation structure is fixedly arranged in the lock body, and the protrusion 12 of the mechanical rotation structure is The direction perpendicular to the groove wall 20 of the groove portion protrudes into the groove portion.

Preferably, the lock body is provided with a groove portion, and the groove portion is composed of a notch 19 and a groove wall 20 extending outward from the notch 19; the mechanical rotation structure is fixedly arranged in the groove wall 20 The protruding parts 12 of the mechanical rotation structure are arranged beyond the groove walls 20 , and the distance between the groove walls 20 is adapted to the protruding distance of the protruding parts 12 . The protruding part 12 of the mechanical rotation structure can be adaptively configured according to the actual application scene, as long as the locked component can be locked in the groove of the lock body.

The working principle of the present invention is: under the default condition of the mechanical rotation structure, the protrusions 12 on both sides of the cam are made It can only move linearly in the chute 16 of the positioning member 9 to realize the rotation of the roller 4 in one direction. The application on the lockset can only realize that the equipment can be locked in the groove portion of the lock body through the one-way movement of the protrusion 12 on the roller 4, but cannot reversely unlock the equipment. After the electromagnet 11 in the mechanical rotating structure is energized, it will generate magnetic force, which will attract the magnetic metal piece 8 on the fixed wheel 7, thereby driving the fixed wheel 7 fixedly connected with the magnetic metal piece 8 to move backward, and then make the fixed wheel 7 helically toothed. 14 and the helical teeth 14 of roller 4 disengage completely, reach the purpose of roller 4 free rotations. When used on a lockset, the protruding part 12 of the roller 4 can be rotated bidirectionally through the insertion of the magnetic card, and the equipment can be taken out from the groove of the lock body, and the default state can be restored after the magnetic card is pulled out.

Please refer to Fig. 4, embodiment one of the present invention is:

A lock for public bicycles. Including the pole, the pole is provided with an annular groove and a card groove, and the annular groove includes a groove mouth 19 and a groove wall 20; the bicycle is provided with a closed surrounding pole 21, and by default, the surrounding pole of the bicycle 21 is locked between the raised corner of the hexagonal roller 4 and the groove mouth 19, thereby locking the bicycle. When people need to use the car, insert the special card into the card slot, so that the electromagnet 11 in the lock cylinder is energized to generate suction, and absorb the U-shaped magnetic metal pull rod on the fixed wheel 7, thereby pulling the fixed wheel 7 to move backward. , so that the one-way helical tooth 14 between the fixed wheel 7 and the roller 4 is disengaged, and the roller 4 can realize forward and reverse rotation, and the locked automatic car can be easily taken out. After the card is taken out, the electromagnet 11 loses power, and the fixed wheel 7 Due to the reverse restoring force of the elastic ring 18, it quickly recovers to cooperate with the helical teeth 14 of the roller 4, and the fixed wheel 7 returns to the state that it can only rotate in one direction.

In summary, the mechanical rotating structure and lockset provided by the present invention are not only simple in structure, small and exquisite, and convenient for popular use; they also have good safety performance and are effective in preventing theft; furthermore, they have good application prospects in the field of municipal design .
