Problems solved by technology

The lock cylinder of common pin locks is mostly one-piece. Technical unlocking tools such as lock guns, steel sheets, screwdrivers, etc. are inserted directly into the keyhole and rotated. It is easy to move or even destroy the pins in the lock cylinder. The lock can be opened forcibly, and its anti-theft performance is poor

Abstract

The invention discloses a combination of an antitheft key and a lock and a using method of the combination. The combination comprises the key (1) and the lock, two rows of teeth are symmetrically on two sides of a key body (1.2) along a central line, a lock core body (3) comprises a first-section lock core body (3.1), a second-section lock core body (3.3) and a third-section lock core body (3.5) which are sequentially arranged axially at intervals, a first connecting body (3.2) and an elastic connecting device used for rotating resetting are arranged between the first-section lock core body (3.1) and the second-section lock core body (3.3), and a second connecting body (3.4) and an elastic connecting device used for rotating resetting are arranged between the second-section lock core body (3.3) and the third-section lock core body (3.5). A lock core is sectionally designed, so that an opening tool is difficulty to be directly inserted and contact with a spring component, and the combination is large in technical unlocking difficulty and good in antitheft performance.

Description

technical field [0001] The invention relates to the field of locks, in particular to a combination of an anti-theft key and a lock head and a use method thereof. Background technique [0002] At present, there are a great variety of locksets on the market with different structures, among which the most widely used in people's lives is the tumbler lock. The lock head of the tumbler lock in the prior art mostly is made up of lock body, lock core, the plectrum linked by lock core and pin assembly, and the lock core is provided with key hole. Its working principle is that when the key corresponding to the lock head is inserted, the tooth surface of the key corresponds to each marble, so that the height of each marble is at the contact surface between the lock body and the lock cylinder, and then the lock cylinder is rotated. The paddle can be driven to drive the dead bolt to unlock. The lock cylinder of common pin locks is mostly one-piece. Technical unlocking tools such as lo...
