The invention discloses a combination of a lock and a key. The combination comprises the lock and the key. A lock cylinder of the lock is divided into a first section lock cylinder, a second section lock cylinder and a third section lock cylinder. A first connection body is arranged between the first section lock cylinder and the second section lock cylinder, and a second connection body is arranged between the second section lock cylinder and the third section lock cylinder. The equipartition line in the width direction of key holes of the first connection body and the second section lock cylinder is identical to the equipartition line, subjected to 90-degree counterclockwise rotation, in the width direction of a key hole of the first section lock cylinder. The equipartition line in the width direction of key holes of the second connection body and the third section lock cylinder is identical to the equipartition line, subjected to 90-degree clockwise rotation, in the width direction of the key hole of the first section lock cylinder. Through sectional design of the lock cylinder, it is difficult for an opener to be inserted to touch a spring component, technical unlocking is difficult, and burglary prevention performance is good.
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, ste...
