In the field of lock technology, the pin lock has always occupied a dominant position. There are many types of pin locks, and the structure and shape are also very different. No matter what kind of pin lock, there is one technical element that is the same. Yes, that is, they all have a pin cylinder, and there are pins on the lock core. The unlocking mechanism is that the key presses the pin to the position where the lock core is released, so that the lock core can be rotated before the lock can be opened. The disadvantage of the tumbler lock cylinder is that the tumbler is in the keyhole, which can be seen intuitively with the eyes, and can be moved directly with things, and the tumbler lock can be easily opened without a key. The lock cylinder has poor anti-prying ability. If t...
