Abstract

The utility model discloses a mechanical pin tumbler lock mid lock which comprises a rotating lock cylinder. A cylindrical pin tumbler or a spring piece is disposed inside the rotating lock cylinder. A surface of the cylindrical pin tumbler or the spring piece is provided with a plurality of slotted holes, and one side face of the cylindrical pin tumbler or the spring piece is connected with springs. The slotted holes correspond to locking clamps and a lock cylinder fixed clamping piece respectively. An anti-locking clamp is disposed on the outside of each locking clamp. Tail portions of the anti-locking clamps are connected with the springs. The anti-locking clamps are disposed inside the mechanical pin tumbler lock mid lock. By means of an ingenious and reasonable structure, the lock clamps are clamped by the anti-locking clamps, so that the mechanical pin tumbler lock mid lock is difficult to open forcedly by external force. Therefore,the mechanical pin tumbler lock mid lock has the advantages of being stable in performance, safe and reliable, outstanding in theft prevention, and capable of effectively avoiding mutual unlocking between the technical unlocking and the unlocking with keys.

Description

The mechanical billiard Lock with inside lock

Technical field

The utility model relates to a kind of mechanical billiard Lock with inside lock, belongs to the lockmaking technical field.

Background technology

The mechanical cylinder lock of prior art except the possibility that has technical unlocking, also owing to have many defectives on the structure, and brings not good on many performances, is easy to opened by the thief.The safe antitheft performance of traditional mechanical cylinder lock is that unlatching of precautionary technology property or strick precaution inartful destruction aspect all can not satisfy the demands.

The utility model content

The purpose of the utility model is the deficiency to prior art, and a kind of reasonable in design is provided, stable performance, and the antitheft advantage is outstanding, safe and reliable mechanical billiard Lock with inside lock.

To achieve these goals, the technical scheme of the utility model employing is: a kind of mechanical billiard Lock with inside lock comprises rotational lock core; Be provided with shell fragment in the rotational lock core; Said shell fragment one side is connected with spring, also has several slotted eyes on the shell fragment surface, and fixedly card is corresponding with pintle hook lock and lock core respectively for said slotted eye; Outside each pintle hook lock, all be provided with and lock card, lock the card afterbody and be connected with spring.

Further, said shell fragment can substitute with cylindrical billiard.

Further, said slotted eye size respectively with pintle hook lock, lock core fixedly card dimensions match.

Further, saidly lock that card is vertical with pintle hook lock to be provided with, the pintle hook lock afterbody to the distance of slotted eye with lock the distance that snaps into slotted eye and equate.

Further, said pintle hook lock afterbody is connected with spring.

Compared with prior art, the advantage of the utility model is: be provided with in the lock core and lock card, through designing ingenious rational structure; Making pintle hook lock locked card blocks; Be difficult to by the rigid unlatching of external force, stable performance, safe and reliable; The antitheft advantage is outstanding, can effectively avoid opening mutually of skilled unlocking and key.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is another structural representation of the utility model.

The specific embodiment

To combine accompanying drawing that the utility model is described further below.

Consult Fig. 1, Fig. 2, a kind of mechanical billiard Lock with inside lock comprises rotational lock core 1; Be provided with shell fragment 2 in the rotational lock core 1, said shell fragment 2 one sides are connected with spring 3, also have several slotted eyes on shell fragment 2 surfaces; In order to ensure safe in utilization, said shell fragment 2 can substitute with cylindrical billiard.Fixedly card 6 is corresponding with pintle hook lock 4 and lock core respectively for said slotted eye, all is provided with in each pintle hook lock 4 outside and locks card 5, locks card 5 afterbodys and is connected with spring 3.Said shell fragment 2 must be being one group more than two; When shell fragment 2 not under the effect at key; If the slotted eye of one group of shell fragment 2 is on the same line, shell fragment 2 will be depressed automatically, locks card 5 and will eject automatically; Lock card 5 and pintle hook lock 4 vertical settings, pintle hook lock 4 afterbodys to the distance of slotted eye with lock the distance of card 5 and equate to slotted eye.

Further, said slotted eye size respectively with pintle hook lock 4, lock core fixedly card 6 sizes match.

Further, said pintle hook lock 4 afterbodys are connected with spring 3.

In the utility model, as lock card 5 locked shell fragment 2, lock just can't be opened, and has only destruction lock core 1 to untie.The utility model is simple in structure, and is easy to use, safe and reliable, can cooperate various lock cores to use.

The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have change and change.All within the spirit and principle of the utility model, any modification of being done, improvement etc. all should be included within the protection domain of the utility model.
