When the key in the mechanical lock hole 11 is rotated so that the lock cylinder contacts the hook portion 465, the inclined portion 4642 of the movable plate 464 abuts against the first cylinder 71. Due to the inclined portion 4642, the inclined portion 4642 moves from the direction close to the main lock tongue 45 to the other side. It can drive the fourth rotating member 7 to rotate counterclockwise, drive the first rotating member 23 to rotate clockwise, and make the second rotating member 32 rotate counterclockwise to release the pressing effect on the oblique locking tongue 31. .

The second stroke slot 4674 , that is, the second stroke slot 4674 extends parallel to the translation direction of the main locking tongue 45 . When the dial 44 rotates against the third convex portion 4671, the bent portion 4672 on the sliding plate 467 pulls the second cylinder 72, drives the fourth rotating member 7 to rotate counterclockwise, and drives the first rotating member 23 to rotate clockwise. The second rotating member 32 is rotated counterclockwise to release the pressing effect on the oblique locking tongue 31 .

The working process of the motor locking of the present invention is that the induction latch 21 extending out of the housing 1 is squeezed into the housing 1 by the door frame, thereby forming an active space for the first rotating member 23, and the first rotating member 23 is released. For the restriction of the second rotating member 32, the second rotating member 32 rotates clockwise to press the oblique lock tongue 31 to the outside of the housing 1; The second antenna 311 is misaligned, the trigger motor 41 is turned on, the tooth 42 rotates to drive the turntable 43 to rotate clockwise, and the dial 44 rotates synchronously, the first swing leg 441 or the second swing leg 442 moves the movable window 472 down to make the limit teeth 473 and the limit post 463 are unlocked, the second swinging leg 442 or the first swinging leg 441 pushes against the first protrusion 461, and drives the inner plate 46 to translate to the right, so that the main lock tongue 45 protrudes out of the housing 1, To achieve motor lock;

The working process of the motor unlocking is that the tooth portion 42 rotates in the opposite direction to drive the turntable 43 to rotate counterclockwise, and the dial 44 rotates synchronously. And the locking post 463 is unlocked, the second swinging leg 442 or the first swinging leg 441 presses against the first convex portion 461, drives the inner plate 46 to translate to the left, so that the main latch 45 retracts into the housing 1 ; The second swinging foot 442 or the first swinging foot 441 continues to move the third convex portion 4671 to drive the sliding plate 467 to move in the direction close to the main lock tongue 45, and the bending portion 4672 pulls the second cylinder 72 to drive the fourth rotating member 7 Rotate counterclockwise to drive the first rotating member 23 to rotate clockwise, so that the second rotating member 32 rotates counterclockwise to release the pressing effect on the oblique locking tongue 31 .

When the breakpoint motor 41 cannot be started, it needs to be manually locked or unlocked. The working process of the mechanical locking is that when the lock cylinder in the mechanical lock hole 11 of the key is rotated, the middle plate 61 is first pressed down, so that the middle plate 61 is downward. Move, drive the third rotating member 64 to rotate and press the mounting plate 62 clockwise to disengage the motor 41 from the tooth portion 42;

Since the dial 44 may be in any position when the power is turned off, that is, the straight line where the first swinging leg 442 and the second swinging leg 441 are located is not necessarily parallel to the direction of the main lock tongue 45 , at this time, the outer plate 47 and the lower surface of the dial 44 The step-like structure 443 is matched, and the movable window 472 is used to rotate the dial 44 in the direction until the first swinging support 442 and the second swinging support 441 are on the horizontal horizontal line;

Of course, the above process also exists in the process of unlocking or locking the motor, so that the dial 44 keeps the first swing leg 442 and the second swing leg 441 on the horizontal line parallel to the main lock tongue 45 before the next operation process, which is convenient for mechanical unlocking or locking. During the locking process, the manual mechanical unlocking keeps the initial state, and the operation is smoother.

Due to the dislocation structure of the middle plate 61, the inner plate 46 and the outer plate 47, when the lock cylinder continues to rotate, the outer plate 47 is pressed down, so that the limit post 463 and the limit tooth 473 are unlocked;

The lock cylinder continues to rotate, and the second convex portion 462 of the inner plate 46 is toggled to drive the main lock tongue 45 to extend out of the housing 1 along with the translation of the inner plate 46 . The movement process of the induction lock tongue 21 and the oblique lock tongue 31 in the above-mentioned mechanical locking process is the same as that of the motor locking process, and will not be repeated here.

The working process of mechanical unlocking is to rotate the lock cylinder anyway, turn the second convex portion 462 to retract the main lock tongue 45 into the housing 1, and continue to rotate to drive the hook portion 465 to translate downward, so that the inclined portion 4642 moves down against Press the first cylinder 71, drive the fourth rotating member 7 to rotate counterclockwise, drive the first rotating member 23 to rotate clockwise, so that the second rotating member 32 rotates counterclockwise to release the pressing effect on the oblique lock tongue 31, so that the oblique lock The tongue 31 can be pushed into the housing 1 against the second torsion spring 312 .

The above-mentioned specific embodiments are used to explain the present utility model, rather than to limit the present utility model. Within the spirit of the present utility model and the protection scope of the claims, any modifications and changes made to the present utility model fall into the scope of the present utility model. scope of protection.
