Detailed Description

As shown in fig. 1-4, the utility model relates to an emergent structure of unblanking of electric lock, including lock shell 1, lock body 2, slider 3, ball 4, lock beam 5, rotor 6, emergent rotor 7, emergent rotor spring 8, motor 9, emergent key 10.

Two through holes 11 are arranged at the top of the lock shell 1. The lock body 2 is fixedly sleeved in the lock shell 1, the top of the lock body 2 is respectively provided with a shaft hole 21 and a lock hole 22, the shaft hole 21 is parallel to the lock hole 22, and the shaft hole 21 and the lock hole 22 on the lock body 2 respectively correspond to the two through holes 11 at the top of the lock shell 1.

The rotary end 51 of the lock beam 5 is movably sleeved in the shaft hole 21 of the lock body 2, the free end 52 of the lock beam 5 is movably sleeved in the lock hole 22 of the lock body 2, two arc-

shaped grooves

53 and 54 are formed in the inner side wall of the lower portion of the rotary end 51 of the lock beam 5, the two arc-

shaped grooves

53 and 54 are arranged up and down, the sliding block 3 is movably installed in the lock body 2, the ball 4 is arranged between the sliding block 3 and the rotary end 51 of the lock beam 5, the ball 4 can be clamped in the arc-

shaped grooves

53 and 54 at the lower portion of the rotary end 51 of the lock beam 5, one arc-shaped groove 53 can enable the lock beam 5 to be in a fixed state, and the other arc-shaped groove 54 can enable. The emergency rotor 7 blocks the other side convex column 62 of the rotor 6 when locked, the emergency rotor 7 is movably installed in the lock body 2, the emergency rotor 7 is opposite to the emergency lock hole 24 on the lock body 2, so that the lock beam 5 is in an unlocking state, two ends of the emergency rotor spring 8 respectively abut between the emergency rotor 7 and the inner cavity wall of the lock body 2, and the lock beam 5 cannot be lifted by external force to drive the rotor 6 to rotate anticlockwise to unlock in a normal state.

The emergency key 10 can be inserted into the emergency keyhole 24 of the lock body 2 and matched with the emergency rotor 7.

As shown in fig. 5 and 6, in the embodiment, two ends of the emergency rotor 7 are the rotating shafts 71 and are movably sleeved in the lock body 2, the emergency rotor 7 includes a limiting portion 72 and a connecting portion 73, both of which are L-shaped, the limiting portion 72 abuts against a retaining wall 251 on the side surface of the boss 25 of the lock body 2, and the limiting portion 72 can block the boss 62 on the other side of the rotor 6, so that the rotor 6 cannot rotate counterclockwise; the boss 25 side of lock body 2 is equipped with a step 252, and after emergent rotor 7 rotated 90 degrees, under emergent rotor spring 8's effect, spacing portion 72 supported with another barricade 253 of the boss 25 of lock body 2 and leaned on, gave rotor 6 anticlockwise rotation and let out the space, but, owing to there is the step 252 to exist this moment, emergent rotor 7 can't return to original position toward gyration 90 degrees.

The utility model discloses a theory of operation:

as shown in fig. 1-8, when the induction lock opener is not powered or the motor 9 fails, the rotor 6 cannot be driven by the motor 9, and at this time, the emergency key 10 is inserted into the emergency lock hole 24 on the lock body 2 and is matched with the emergency rotor 7, so that the emergency rotor 7 rotates 90 degrees, the rotor 6 rotates counterclockwise to leave a space, the lock beam 5 is lifted upwards by external force, and because the convex column 61 on one side of the rotor 6 is movably inserted into the sliding groove 31 of the slider 3, and the sliding groove 31 and the slider 3 horizontally move at an acute angle, the lock beam 5 is lifted up to apply a force to the ball 4 and the slider 3 rightward, so that the rotor 6 rotates counterclockwise, that is, the motor 9 is driven to rotate reversely, and unlocking is achieved. Because the side surface of the convex column 25 of the lock body 2 is provided with a step 252, the emergency rotor can not be rotated to the original position to limit the convex column 62 at the other side of the rotor 6, so that the emergency unlocking under the condition of electronic function failure is effectively managed.

The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited thereby, and all equivalent changes and modifications made within the scope of the claims and the specification should be considered within the scope of the present invention.
