Background technique

A common pin lock consists of a lock cylinder, a lock body, a pin and a spring. Among them, the lock core and the lock body are provided with several groups of radial pinholes, which communicate with the keyhole on the lock core. Each pinhole There are two marbles in the hole, and the spring is arranged in the pin hole and is located at one end of the lock body. In the natural state, the spring presses the two pins against the key hole. At this time, the two pins in each pin hole The contact surface is located in the lock cylinder, and the lock cylinder cannot be rotated; when the matching key is inserted, the ends of the pins in the lock core are against the corresponding alveoli of the key, so that the contact surface of the two pins in each pin hole It just coincides with the mating surface between the lock cylinder and the lock body, and the lock cylinder can rotate. Technical unlocking is usually to use an unlocking tool such as iron wire to move the pins in the pin holes through the key hole, so that the contact surfaces of the two pins in each pin hole are located on the mating surface of the lock cylinder and the lock body. The method is: Toggle the marbles in each pinhole, after dialing the pinholes in one of the pinholes, turn the lock cylinder once so that the pinholes in the pinholes cannot be reset, then toggle the pinholes in the next pinhole, and turn again Click the lock cylinder until the pins in all the pin holes are set, and the lock can be opened.

In order to increase the difficulty of technical unlocking of the tumbler lock, the invention patent application document with the notification number CN1970978A discloses "a kind of anti-dialing lock". In a basic scheme disclosed by it, the lock includes a lock body and a lock cylinder, wherein , the lock cylinder is provided with multiple groups of pinholes, each group of pinholes is composed of radial angle pinholes and side pinholes whose axes are perpendicular to each other, wherein one end of the angle pinholes communicates with the keyhole; one end of the side pinholes It is connected to the middle of the angle pin hole, and the other end extends to the lock body; there is an angle pin in the angle pin hole, and the angle pin is in the shape of an ax near the key hole, and the other end is set to press it on the key hole. For the spring, the outer wall of the angle pin is provided with a dimple; the side pin hole is provided with a side pin, and the lower end of the side pin matches the dimple on the angle pin. The working principle of the lock is: in the natural state, the dimple on the angle pin is located on the side of the bottom of the side pin hole close to the keyhole, and the side pin is under the elastic force of the spring or under the repulsion of the magnet or under the action of gravity. Press against the outer wall of the angle pin, and the upper end extends into the lock body, so that the lock cylinder cannot be rotated; when the matching key is inserted, the tooth groove on the key pushes the angle pin to move axially, and makes the dimple on the angle pin Align the hole of the side pin. At this time, the lower end of the side pin is inserted into the recess on the angle pin, so that the upper end surface of the side pin leaves the lock body and moves to the mating surface of the lock cylinder and the lock body, and the lock cylinder can rotate. In the above-mentioned patent solution, the matching between the tooth socket on the key and the ax head on the angle pin must meet the height and angle parameters at the same time to open the lock, which increases the difficulty of technical unlocking. However, it still has the following disadvantages: since the side pins always have a tendency to move downward under the elastic force of the spring or under the repulsive force of the magnet or under the action of gravity, as long as the dimples on the angle pins are aligned with the side pin holes one by one Alignment, the side pins are automatically inserted into the recess to lock the angle pins so that they cannot be reset, that is, there is a linkage relationship between the side pins and the angle pins. Therefore, as long as you use the unlocking tool to slowly move the angle pins, the dimples on the pins must be aligned with the side pin holes at a certain moment, so that the lock can be unlocked by pushing the pins in each pin hole one by one, making the lock It's still relatively easy to get rid of.
