Description

A kind of idle-run lock head

Technical field

The utility model relates to a kind of lock, and in particular, it relates to a kind of idle-run lock head.

Background technology

The patent No. is the patent that ZL 2012202154405 is called " a kind of Mortise lock ", although its mutual opening rate is low, the anti-technical opening of energy, it does not have lost motion functionality, and violence is opened and still had an opportunity to take advantage of.

Utility model content

In order to overcome the shortcoming of above-mentioned patent, the utility model provides the idle-run lock head that a kind of energy violence is opened.

The utility model is achieved in that it comprises lock body, lock core, turning set, and described turning set overlaps lock core and puts into together in lock body, and turning set is main body of unblanking; Have hinge groove at lock core, in-builtly open reeded hinge and spring, or have marble hole at lock core, in-built pellet and the spring having groove or annular groove; The groove of described hinge or the groove of pellet or annular groove, what be set to promote by spring is vertical or near normal limit, and what promote by key tooth flower one is set to hypotenuse; Longitudinally have lock pin groove, built-in lock pin, the inner of lock pin and the fit depressions of hinge at lock core, or match with the groove of pellet or annular groove; At turning set, the place corresponding to lock pin has clutch cotter way, built-in on-of pin; Have lock slots in the place of the corresponding on-of pin of lock body, in lock slots, be provided with unblank pellet and spring.

After taking technique scheme, when unblanking, when the key mated inserts, the groove of hinge or the groove of pellet or annular groove will align, under the effect of unblank pellet and spring, on-of pin moves inward together with lock pin, the inner of lock pin enters into the groove of hinge or the groove of pellet or annular groove, the outer end of on-of pin is exited from the lock slots of lock body, maintain an equal level with the external surface of turning set, its the inner enters lock core card between lock core and turning set, lock core and turning set are connected as a single entity, now twist key and just can unblank; During locking, extract key, hinge or pellet move under the effect of key tooth flower, its groove or annular groove force lock pin move outward together with on-of pin, the outer end of on-of pin enters the lock slots of lock body, its the inner is exited from lock core, maintain an equal level with the inner surface of turning set, at this moment, on-of pin is stuck between turning set and lock body and defines lock-out state, is separated between lock core with turning set, and lock core is in idling conditions, now lock core can rotate arbitrarily and lock and can not be unlocked, so the utility model has the performance that very strong defense technique is opened and violence is opened.

Detailed description of the invention

Fig. 1 first embodiment of the present utility model, it comprises turning set 3 described in lock body 1, lock core 2, turning set 3 and overlaps lock core 2 and put into together in lock body 1, and turning set 3 is main body of unblanking; Have hinge groove at lock core 2, in-built hinge 4 and the spring having groove 41, the spring of hinge 4 is arranged on the top of hinge 4, and what the groove 41 of hinge 4 promoted by spring is set to vertical or near normal limit, by key tooth flower promote while be set to hypotenuse; Longitudinally have lock pin groove, built-in lock pin 5 at lock core 2, match with the groove 41 of hinge in the inner of lock pin 5, at turning set 3, the place corresponding to lock pin 5 has clutch cotter way, built-in on-of pin 6; Have lock slots in the place of the corresponding on-of pin 6 of lock body 1, in lock slots, be provided with unblank pellet 7 and spring.

During unlatching, when the key of coupling inserts lock core 2, under key tooth flower promotes, the groove 41 of all hinges 4 aligns, and under the effect of unblank pellet 7 and spring, lock pin 5 moves inward together with on-of pin 6, the inner of lock pin 5 enters the groove 41 of hinge 4, the outer end of on-of pin 6 is exited from the lock slots of lock body, maintains an equal level with the external surface of turning set, now twists key and just can open, during locking, in the process of extracting key, hinge 4 moves under the effect of key tooth flower, its groove 41 forces lock pin 5 move outward together with on-of pin 6, the outer end of on-of pin 6 enters the lock slots of lock body 1, its the inner is exited from lock core 2, maintain an equal level with the inner surface of turning set 3, at this moment, on-of pin 6 is stuck between turning set 3 and lock body 1 and defines lock-out state, be separated between lock core 2 with turning set 3, lock core 2 is in idling conditions, now lock core 2 can rotate arbitrarily and lock and can not be unlocked, so the utility model has the performance that very strong defense technique is opened and violence is opened.

Fig. 2 is second embodiment of the present utility model, it and first embodiment unlike, the spring of hinge 4 is arranged on the medium position of hinge 4.

Fig. 3 is the 3rd embodiment of the present utility model, it and above-mentioned two embodiments unlike, the spring of hinge 4 is arranged on the lower position of hinge 4.

Fig. 4 is the 3rd embodiment of the present utility model, it and above-mentioned three embodiments unlike, hinge 4 by special-shaped marble 4 is substituted

Fig. 5 is the 5th embodiment of the present utility model, and it and above-mentioned four embodiments are unlike, hinge 4 by circular type pellet 4 is substituted, and groove 41 is substituted by annular groove 41.

Above embodiment is only preferred embodiment of the present utility model, and create the prerequisite of design at the utility model under, can also make some embodiments, these all belong to protection domain of the present utility model.
