Problems solved by technology

[0003] The defects of the above-mentioned springless blade lock head are: 1. Since the blade can be rotated directly in the lock cylinder, it is easy to turn the blade with foreign matter, and the anti-technical opening performance is not very good; 2. During use, the blade is subjected to external forces such as vibration Rotation will also occur when turning, causing the key slots on the blades to be inconsistent, and the key needs to be rotated and inserted repeatedly, which is very inconvenient to use; 3, the multiple blade holes of the above-mentioned blade lock head are inconvenient to process

Abstract

The invention discloses a lock which comprises a lock shell and a lock cylinder and is characterized in that a key is inserted into a key hole of the lock cylinder; a safety lever lifting slot communicated with the key hole is arranged on one side of the key slot on the lock cylinder; a safety lever is arranged in the safety lever lifting slot; a blade hole is also arranged on the lock cylinder; multiple blades in close connection and capable of moving transversely in the blade holes are arranged in the blade holes; each blade is provided with a blade inner hole for insertion of the key; a blade clamp block is arranged in the blade inner hole; a blade upper clamp slot for clamping the safety lever is arranged at the upper end of each blade; the key drives the blades to move transversely, and the blade upper clamp slots at the upper ends of multiple blades are arranged into a groove for the safety level to fall in; and the safety lever also comprises a fastening strip which can be clamped in the groove. The lock disclosed by the invention has higher anti-theft performance, very low mutual-opening rate and great secret key quantity, and is convenient to use.

Description

【Technical field】 [0001] This invention relates to a lock, and more particularly to a blade lock. 【Background technique】 [0002] At present, the traditional springless blade lock is generally composed of a lock cylinder and a shell. The blades can rotate at a certain angle in the lock cylinder. Each blade is provided with a hole for the key to be inserted. After the blade rotates at a certain angle, the bumper on the lock cylinder falls and snaps into the blade upper groove at the upper end of the blade, and the key can drive the lock cylinder to rotate relative to the housing to unlock. [0003] The defects of the above-mentioned springless blade lock head are: 1. Since the blade can be rotated directly in the lock cylinder, it is easy to turn the blade with foreign matter, and the anti-technical opening performance is not very good; 2. During use, the blade is subjected to external forces such as vibration Rotation also can take place when rotating, causes the key slot o...
