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 an antitheft key-and-cylinder combination and an application thereof. The antitheft key-and-cylinder combination comprises a key (1) and a cylinder. Bits are distributed on one side of a key body (1.2) along the length. A plug (3) comprises a first plug section (3.1), a second lock body section (3.3) and a third lock body section (3.5) which are arranged at intervals axially; a first connector (3.2) and an elastic connection device which is used for rotational resetting are arranged between the first plug section (3.1) and the second plug section (3.3); a second connector (3.4) and the other elastic connection device which is used for rotational resetting are arranged between the second plug section (3.3) and the third plug section (3.5). Owing to the sectional design of the plug of the antitheft key-and-cylinder combination, it's difficult for people to insert an unlocking tool directly to touch a pin component, technical unlocking difficulty is increased, and antitheft performance is good.

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 keyhole. 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 loc...
