Description

Safety locks and their keys capable of swallowing tinfoil, soft rubber and similar lockpicking tools

technical field

The utility model relates to the technical field of locks, in particular to a safety lock capable of swallowing tin foil, soft glue and similar unlocking tools.

Background technique

With the improvement of people's living standards and the acceleration of the pace of life, people's awareness of prevention is also increasing. Therefore, there are many kinds of anti-theft locks sold on the market, each of which has different design concepts, and strives to meet the anti-theft requirements of different users.

The tumbler structure lock is the most commonly used lockset today, and is suitable for interior and exterior doors of various buildings. Generally, a tumbler structure lock includes two main parts, a fixed lock cylinder and a movable lock cylinder. A number of corresponding radial pinholes are provided in the fixed lock cylinder and the movable lock cylinder respectively, and a flat-head pinball and a round-head pinball are placed in each pinhole. An elastic device is also arranged in the pin hole of the fixed lock core, so that the flat-headed pins are close to the round-headed pins. In the locked state, the flat-headed marble is stuck at the interface between the fixed lock cylinder and the movable lock cylinder. There is a keyhole on the outer end of the movable lock cylinder. When the matching key is inserted into the keyhole, the round pins in the pin holes of the movable lock cylinder will be squeezed by the keyhole and move towards the direction of the flat pins, so that each flat pin will The contact surface with the round-headed marble forms a cylindrical surface, and is flush with the junction surface of the fixed lock cylinder and the movable lock cylinder, forming an open state. In this state, the key can turn the movable lock cylinder to open the pin structure lock. If no key is put in or a key that does not match the movable lock cylinder is put in, the flat-headed marble will be stuck at the interface between the fixed lock cylinder and the movable lock cylinder under the pressure of the elastic device, and the key will not be able to turn the movable lock cylinder, and the lock will be locked. cannot be turned on.

However, the existing pin lock can resist the pin after the key is inserted into the key hole, and the pins in the lock are all arranged in the cavity where the key hole is located, so that the perpetrator of theft can insert the key hole through a master key or other unlocking tools, contact and squeeze the pin. The anti-theft performance is not strong when the marble is pressed to unlock, thereby restricting the popularization and application of the anti-theft lock, and there is a potential safety hazard.

For this reason, it is necessary to develop a safety lock that is easy to manufacture, and the marble and the keyhole are misplaced, that is, the perpetrator of the theft cannot directly contact and squeeze the pinhole after inserting the master key or other unlocking tools into the keyhole.
