Lock picking prevention device
The invention relates to a hardware lock, in particular to a lock picking prevention device which is mainly composed of a key cylinder, a key cylinder sleeve, a lock plunger, a lock plunger sleeve, a picking prevention seat and a picking prevention seat sleeve, wherein one end of the lock plunger is connected with a key cylinder shaft; a radial groove and an axial direction groove are formed in the other end of the lock plunger; the two grooves are communicated; one end of the lock plunger sleeve is connected with the key cylinder; an axial open groove is formed in the other end of the lock plunger sleeve; and the key cylinder sleeve is arranged in a poison opposite to the picking prevention seat sleeve. The picking prevention lock device is characterized in that the picking prevention seat is loaded in the picking prevention seat sleeve; a lock plunger pin is arranged in the picking prevention seat; a separation prevention device used for preventing the picking prevention seat from separating from the picking prevention seat sleeve is arranged between the picking prevention seat and the picking prevention seat sleeve; and a damping device is arranged between the picking prevention seat and the picking prevention seat sleeve. The lock picking prevention device has the functions that when a thief picks a lock through a violent tool, the key cylinder shaft does not rotate due to clamping of a lock tumbler, and if the thief forcedly twists, the lock plunger drives the picking prevention seat to rotate along with the violent tool after overcoming the resistance of the damping device, so that the key cylinder is prevented from being twisted to be damaged.
