Abstract
The invention discloses a hole bending type security lock head. A shaft sleeve is connected to an inner hole of a lock body; a lock cylinder is connected to an inner hole of the shaft sleeve; a plurality of through holes through which the shaft sleeve is communicated with the lock cylinder are formed in the lock body from the top down; a front marble, a middle marble, a rear marble, a spring and a plug are sequentially arranged in each through hole from the inside out; a working bin is arranged between a security plate and the upper end surface of the lock cylinder; and a bent passage is defined by a lock hole, the working bin and a key hole in the lock cylinder. When a key is inserted, a gap between the front marble and the middle marble is aligned with that between the lock cylinder and the shaft sleeve. When the lock cylinder is rotated, the lock hole is staggered from the key hole and the key hole is covered. When the key is rotated with the lock cylinder to a marble position on the shaft sleeve, the gap between the middle marble and the rear marble is aligned with that between the shaft sleeve and the lock body, and the key can drive the lock cylinder and the shaft sleeve to rotate jointly, and therefore, locking or unlocking can be realized.
Description
