Abstract

The invention discloses a combination of a lock and a key. The combination comprises the lock and the key. The lock cylinder of the lock comprises a first section of lock cylinder body, a second section of lock cylinder body and a third section of lock cylinder body. A first connector is disposed between the first section of lock cylinder body and a second section of lock cylinder body. A second connector is disposed between the second section of lock cylinder body and the third section of lock cylinder body. The averaging line along the keyhole width direction of the first section of lock cylinder body rotates 90 degrees anticlockwise to form the averaging line of the first connector and along keyhole width direction of the second section of lock cylinder body. The averaging line along the keyhole width direction of first section of lock cylinder body rotates 90 degrees clockwise to form the averaging line of the second connector and along the keyhole width direction of the third section of lock cylinder body. The combination of the lock and the key has the advantages that the lock cylinder is sectioned, a lock picking tool is difficult to reach a tumbler component, and the combination is difficult to pick and good in antitheft performance.

Description

technical field [0001] The invention relates to the field of locks, in particular to a combination of a lock head and a key 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 lock guns, st...
