Document Type and Number:
WIPO Patent Application WO/2019/232658
Kind Code:
A1
Abstract:
A pin tumbler lock that allows for pin positions to be easily changed by means of horizontal pushing by a flat plate, comprising an upper stopper block (2), a lower stopper block (7), a movable pin chamber (4), a fixed pin chamber (5), springs (3), pins (6) with different lengths, a latch (1) and an outer iron plate, being able to allow for easy changing of the positions of the pins with different lengths, increasing the difficulty in unlocking by increasing different arrangement combinations regarding the lengths of the pins or by increasing the number of placed pins, and being able to form different models by increasing the distance between the pins. By means of modification, said lock is applicable to all places where a lock is needed, such as a safe box, security door and padlock, etc.
