Angle spring lock

Abstract

The invention belongs to the technical field of locks, and particularly relates to an angle spring lock. The angle spring lock comprises a lock shell, a lock cylinder and a key. The lock cylinder is provided with a key hole. The upper side of the key hole is provided with an angle lower spring. Both the height level difference and the angle level difference are set for the angle lower spring. The lower side of the key hole is further provided with a snake slot spring. According to technical opening, the height position of the angle lower spring needs to be positioned, and meanwhile the angle position of the angle lower spring also needs to be positioned. Only when the two positions are well positioned at the same time, can the angle lower spring be in an opened state. Meanwhile, the snake slot spring also needs to be shifted to the accurate position, and then the lock can be opened. Due to the fact that different moving directions and different angle rotating directions are needed for opening, the technical opening difficulty is quite high, accordingly, the anti-theft performance is better, and safety is higher.

Description

technical field [0001] The invention belongs to the technical field of locks, in particular to an angle tumbler lock. Background technique [0002] Locks are very common and very common appliances in people's daily life, especially in large places, such as hotels, offices, security agencies, homes, etc., locks are used to protect important items from being stolen, and a lock The core anti-theft part is the lock cylinder. The performance of the lock cylinder directly affects the anti-theft performance of the entire lock. Most of its structure is that the upper and lower pins are in a point-to-point contact and separated. This structure has been researched and deciphered by many illegal unlockers. The technical opening principle is to first apply a certain torque to the lock cylinder to misalign the upper and lower pins, and then pull or hit the lower pins to separate the upper and lower pins to achieve the purpose of unlocking, especially the various unlocking tools nowadays....
