As shown in attached figures 1 to 4, the anti-riot lock body comprises a lock shell 1, a clutch base 2 capable of rotating is installed on the lock shell 1, a rotor 3 is sleeved in the clutch base 2, a clutch device is arranged between the clutch base 2 and the rotor 3, and under the action of the clutch device, the rotor 3 can rotate synchronously along with the clutch base 2 or the rotor 3 can rotate relative to the clutch base 2.

Specifically, the clutch device includes a clutch pin 41 and an elastic member 42 provided on the clutch base 2, the elastic member 42 being a spring; the rotor 3 is provided with a chucking hole 31; under the action of elastic member 42, clutch pin 41 exits from the engaging hole 31 of rotor 3 and retracts in clutch seat 2; under the urging of an urging mechanism 5, the clutch pin 41 is inserted into the card hole 31 against the spring. The pushing mechanism 5 comprises a motor which is installed and fixed inside the lock body, the motor is connected with a push plate 51 through a speed reducing mechanism, the push plate 51 is an arc-shaped plate, and the push plate 51 moves up and down along the axial direction of the clutch pin 41 under the action of the motor.

The inventor finds that when the handle and the lock body are not linked under the action of the clutch in the using process, if a violent destructor presses one end of the handle by utilizing the principle of a lever, the central shaft of the rotor 3 connected with the handle deviates from the central shaft of the clutch seat 2, the rotor 3 is tightly matched with the clutch seat 2, the clutch seat 2 is driven by the rotation of the handle, so that the violent unlocking can be realized, and the potential safety hazard exists.

The clutch seat 2 is provided with an abutment portion 21, in particular, the abutment portion 21 is a projection formed on the outer side face of the clutch seat 2. The lock shell 1 is provided with a limiting piece 6 with a limiting part 61 corresponding to the abutting part 21, when the rotor 3 can rotate relative to the clutch seat 2, the limiting part 61 abuts against the abutting part 21 to prevent the clutch seat 2 from rotating along with the rotor 3, and when the rotor 3 can rotate along with the clutch seat 2 synchronously, the limiting part 61 is separated from the abutting part 21 to allow the clutch seat 2 to rotate along with the rotor 3 synchronously.

The pushing mechanism 5 is connected to a driving member 52 capable of driving a linear reciprocating motion, and the driving member 52 is formed on the push plate 51.

The driving member 52 can have various forms, one of which is that the driving member 52 is provided with an abutting head 53, the upper end surface of the abutting head 53 is provided with an abutting part 531, the lower end surface is provided with a pulling part 532, the limiting member 6 can be rotatably installed in the lock shell 1 relative to the lock shell 1, as shown in fig. 5 and 6, the limiting member 6 is provided with an abutted part 62 and a pulled part 63; when the driving element 52 is straight upward, the abutting portion 531 abuts against the abutted portion 62 to rotate the limiting member 6 clockwise, and the limiting portion 61 is separated from the abutting portion 21; when the driver 52 is linearly downward, the pulling portion 532 pulls the pulled portion 63, the restricting member 6 rotates counterclockwise, and the restricting portion 61 abuts on the abutting portion 21 by the gravity (H direction in the figure).

The driving member 52 is alternatively provided with straight teeth, and the limiting member 6 is rotatably mounted in the lock case 1 relative to the lock case 1 and has a plurality of external teeth arranged around a central rotation axis thereof and engaged with the straight teeth; when the driver 52 is linearly upward, the regulating member 6 is rotated clockwise, and the regulating portion 61 is separated from the abutting portion 21; when the driver 52 is linearly downward, the restricting member 6 rotates counterclockwise, and the restricting portion 61 abuts on the abutting portion 21, which is not shown in the drawing.

The limiting piece 6 can be rotatably installed on the lock shell 1 through a pin relative to the lock shell 1, but the mode is not firm in connection with the lock shell 1 and is easy to loosen, so that another mode can be adopted, namely the lock body comprises a latch bolt assembly, the latch bolt assembly is provided with a guide rod 71, a connecting piece 72 is fixedly arranged on the lock shell 1, the connecting piece is provided with a through hole, the guide rod 71 can automatically penetrate through the through hole in a sliding mode, the limiting piece 6 can be rotatably installed on the connecting piece through a pin relative to the lock shell 1, firmness and stability are achieved, and the hidden danger of preventing violent unlocking is improved.
