Blade-type lock closed and opened under control of lifting of brake rod, and key

Abstract

The invention provides a blade-type lock closed and opened under the control of lifting of a brake rod, and a key, belonging to a hardware lock manufacturing technology. Under the cooperation of a blade, a safety lever, a start key, a tail sleeve and the brake rod, the safety lever can be dropped by means of the key to drive the brake rod to fall simultaneously, so that the brake rod locked in the lock is separated; and the key is capable of driving the key cylinder and the tail sleeve to rotate together, thus unlocking the lock; otherwise, the key is drawn out so that the brake rod enters the lock again and is locked in a braking groove; and then, the lock cylinder can be only idled and the lock is closed. The blade-type lock provided by the invention is novel in design, rational in structure, large in key quantity and good in safety performance. The blade-type lock comprises such components as the lock (1), wherein a kidney slot (10) is formed outside the lock cylinder (2); a safetylever groove (12) is formed on the lock cylinder (2); the safety lever (13) is assembled in the safety lever groove (12); the brake rod (19) is vertically connected in the tail sleeve (18); and the start button (20) on the rear end of the safety lever (13) is connected into the cambered groove (19-1) of the brake rod (19).

Description

Technical field: [0001] The invention relates to a blade-type mechanical lock head, in particular to a blade-type lock head and a key whose lock is closed and opened by lifting and lowering a brake lever, and belongs to the hardware lock manufacturing technology. Background technique: [0002] At present, consumers report that there are structural weaknesses in the "idling" locks currently in use, resulting in unsatisfactory failure rates and safety performance of the locks. The common problem of the V-shaped groove blade is that the digital combination and the V-shaped locking lever have a chance to produce a half-neutral position after closing, resulting in a high mutual opening rate; especially the design defect of the opening and closing device of the lock cylinder behind the locking device makes the lock The core may be in a half-open state, so the original key will often produce idling after the key is inserted and the lock cannot be opened. On the contrary, the idling...

Problems solved by technology

[0002] At present, consumers report that there are structural weaknesses in the "idling" locks currently in use, resulting in unsatisfactory failure rates and safety performance of the locks.

The common problem of the V-shaped groove blade is that the digital combination and the V-shaped locking lever have a chance to produce a half-neutral position after closing, resulting in a high mutual opening rate; especially the design defect of the opening and closing device of the lock cylinder behind the locking device makes the lock The core may be in a half-open state, so the original key will often produce idling after the key is inserted and the lock cannot be opened. On the contrary, the idling device will not idle after the non-original key is inserted into the key slot. This is where the downside of conventional idle locks lies
