Detailed Description
Example (b): an automatic lock body structure comprises a lock body shell 1, a dead bolt 2, an oblique bolt 3, a knob 4, a battery and a motor 5, wherein the dead bolt 2 and the oblique bolt 3 can be respectively installed on the lock body shell 1 in a sliding mode with a set distance, the dead bolt 2 and the oblique bolt 3 can respectively extend out of the outer side of the lock body shell 1 with a set distance, the knob 4 can be installed in the lock body shell 1 in a rotating mode, a shifting rod 6 is arranged on the side wall of the knob 4, the shifting rod 6 can shift the dead bolt 2 to slide, the battery and the motor 5 are fixedly installed in the lock body shell 1, the battery provides power for the motor 5, a transmission gear 7, a knob gear 8, a shifting gear 9 and a baffle assembly 10 are further arranged, the transmission gear 7 and the shifting gear 9 can be respectively installed in the lock body shell 1 in a rotating mode, the knob gear 8 is coaxially and fixedly connected with the knob 4, the, knob gear 8 and the meshing transmission of stirring gear 9, baffle subassembly 10 can be rotated locate lock body shell 1 in, stir gear 9 and rotate and to stir baffle subassembly 10 one end and make baffle subassembly 10 revolve the axis of rotation, the baffle subassembly 10 other end can tightly support the oblique tongue 3 and be located the inside one end of lock body shell 1 and prevent that oblique tongue 3 slides to lock body shell 1 inside.
The motor 5 drives the knob 4 through the transmission gear 7 to rotate, and when the square bolt 2 is stirred to slide to realize unlocking, the baffle plate assembly 10 is driven to rotate through the stirring gear 9, so that the oblique bolt 3 is separated from one end inside the lock body shell 1 to realize unlocking, the structure increases the force value of the motor 5 through the lever mechanism, the force of the motor 5 is increased, and the situation that the door cannot be opened by the dead automatic lock body is avoided.
The distance from one end of the flapper assembly 10 to the hinge axis 17 is greater than the distance from the other end of the flapper assembly 10 to the hinge axis 17. The effect of amplifying the force of the motor 5 is achieved.
Can also the pivoted be equipped with gear drive spare 11 in the lock body shell 1, gear drive spare 11 one end can tightly be supported on the lateral wall of baffle subassembly 10 one end, and stir gear 9 and can stir the gear 9 driving medium other end and make it rotate. The poking gear 9 pokes the baffle plate assembly 10 through the gear transmission part 11, so that a two-position lever mechanism is formed, the force value of the motor 5 is increased in a doubling mode, the force of the motor 5 is exerted to the maximum, and therefore the situation that the door cannot be opened by the deadlocking automatic lock body is avoided.
The toggle gear 9 is provided with a convex structure 12, and the convex structure 12 is just stopped on the side wall of the other end of the gear transmission member 11. When the toggle gear 9 rotates, the protruding structure 12 on the toggle gear drives the gear transmission member 11 to rotate against the other end side wall of the gear transmission member 11, which is simple in structure and convenient to implement, and in addition, the toggle gear 9 can be implemented in a manner of being hinged with the gear transmission member 11 or in a manner of being in meshing transmission, which is an equivalent alternative structure that can be easily thought of by those skilled in the art according to the present patent, and belongs to the protection scope of the present patent.
Still be equipped with a locating part on the lock body shell 1 inside wall, the locating part can restrict the turned angle of gear driving spare 11. The limiting piece limits the rotation angle of the gear transmission piece 11, and the situation that the gear transmission piece is separated from the baffle plate assembly 10 due to the fact that the rotation angle is too large is avoided.
The limiting member is a stop pin 13, a protruding stop arm 14 between two ends is arranged on the outer circumferential side wall of the gear transmission member 11, and the stop pin 13 is stopped on the side wall of the stop arm rotating towards the direction of the end, away from the latch bolt 3, of the toggle baffle component 10. The structure informs the stop pin 13 of the stop arm on the gear transmission member 11 to limit the rotation angle of the gear transmission member 11, and in addition, the gear transmission member 11 can also be provided with an arc hole for the sliding insertion of the convex structure 12 on the transmission gear 7 or the sliding insertion of the stop pin 13.
One end of the gear transmission part 11 is provided with a roller 15, and the side wall of the roller 15 can roll along the side wall of the baffle plate component 10. The baffle plate assembly 10 is shifted through rolling friction, friction is small, and smooth shifting of the baffle plate assembly 10 is guaranteed.
The baffle plate component 10 is of an L-shaped structure, and one end of the baffle plate component 10 is in contact with the roller 15 through an inclined plane which forms an included angle with one end of the gear transmission component 11. This structure make full use of the inside vacant space of lock body shell 1, avoided lock body shell 1 bulky, through inclined plane and the contact of gyro wheel 15, avoided appearing the condition emergence that the vertical contact leads to unable stirring.
Also disposed within the lock body housing 1 is a striker return spring 16, the striker return spring 16 providing a resilient retention force to the striker assembly 10 that maintains a position preventing retraction of the latch bolt 3 into the lock body housing 1. After the lock body is unlocked, the baffle plate resetting elastic piece 16 realizes the automatic resetting of the baffle plate assembly 10, ensures that the latch bolt 3 automatically enters a door locking state, and avoids the situation of forgetting to lock the door.
