The lock cylinder is located inside an inner cavity of the lock body, a key hole is arranged on the lock cylinder, two sides of the inner cavity of the lock body are equipped with clamp slots, two sides of the lock cylinder are connected with shift wheels, the lower edge portion of each shift wheel is connected with a clamp core, the clamp cores extend into the clamp slots, the lock cylinder is equipped with a spring or a snap spring for pushing the shift wheels to rotate to enable the clamp cores to extend into the clamp slots, the shift wheels are fixedly connected with shift wheel handles extending to the key hole, ejector pins engaged with the shift wheel handles and a key handle form a key. The pin type anti-theft lock is high in unlocking difficulty and simple in manufacturing, and has high anti-theft property.

Description

The pin type theftproof lock

Technical field

The utility model relates to a kind of lock that is used on the door, especially a kind of pin type theftproof lock.

Background technology

Existing lockset has cylinder lock, digital cipher lock etc.Cylinder lock is backward in technique, causes anti-theft feature relatively poor thereby opened by the people easily, has been in the edge that is eliminated.Digital cipher lock has increased the difficulty of anti-pirate of the open, and anti-theft feature is stronger, but is easy to be snatched password by the people, thereby does not have anti-theft feature.

The utility model content

The technical problems to be solved in the utility model provides the pin type theftproof lock that a kind of opening difficulty is big, anti-theft feature is good.

For solving the problems of the technologies described above, technical solution adopted in the utility model is: it is made of lock body, lock core and hammerlock, and lock core is arranged in the inner chamber of lock body, has keyhole on lock core, it is characterized in that: the both sides at the inner chamber of lock body have draw-in groove; Transferring in lock core has and the corresponding thumb wheel of draw-in groove quantity, and the following portion switching of thumb wheel has the core of the card, the core of the card to stretch in the draw-in groove; Being provided with the rotation of promotion thumb wheel on lock core makes the core of the card stretch into the spring or the jump ring of draw-in groove; Be connected with the thumb wheel handle that stretches to keyhole on thumb wheel, thimble that matches with the thumb wheel handle and the shank of the key form key.

Adopt the beneficial effect that technique scheme produced to be: the utility model is positioned at the different position of thumb wheel limit portion by the core of the card, each thumb wheel is rotated drive the distance difference that the core of the card stretches out draw-in groove, the cooperation of the diverse location by a plurality of thumb wheels again, make originally be locked in when opening can only be simultaneously with many thimbles stretch into keyhole different apart from opening.The utility model is opened the difficulty height, is made simply, has higher theftproof.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

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

Fig. 2 is the vertical view of key of the present utility model.

The specific embodiment

As shown in Figure 1, this pin type theftproof lock is made of lock body 3, lock core and hammerlock 1, and lock core is arranged in the inner chamber of lock body 3, has 3 draw-in grooves 7 in the both sides of the inner chamber of lock body 3, and the quantity of draw-in groove 7 can have 4-8 with manufacturing process as required.Have and draw-in groove 7 corresponding thumb wheels 6 in the switching of the both sides of lock core, the following portion axle of thumb wheel 6 is connected with the core of the card 5, and the core of the card 5 stretches in the draw-in groove 7, and the thumb wheel 6 of the same side is in different vertical planes.Be provided with jump ring 4 between lock core and thumb wheel 6, under the effect of jump ring 4, the core of the card 5 heads into forward in the draw-in groove 7, and jump ring 4 also can be that promotion thumb wheel such as spring rotates and makes the core of the card stretch into the elastic device of draw-in groove.This pin type theftproof lock is connected with the thumb wheel handle 10 that stretches to keyhole on thumb wheel 6, match with on the key thimble 8, and when using key operated lock, each thumb wheel 6 rotates and makes the core of the card 5 just in time withdraw from draw-in groove 7.As shown in Figure 1, 2, the key of this pin type theftproof lock is made of thimble 8 and the shank of the key 9, and the position of thimble 8 on the vertical plane of the shank of the key 9 is corresponding with its pairing thumb wheel.

As shown in Figure 1, this pin type theftproof lock is provided with pressing spring 13 down between lock core top and lock body inner chamber; Lock body inner chamber transfer on lock core top is connected to opens lever 12, opens lever 12 and is connected with dead bolt 2 by connecting rod 14; An end at the hammerlock 1 of U-shaped has the locked groove that cooperates with dead bolt 2, is provided with to open spring 13 between hammerlock 1 another end and lock body inner chamber.Unlatching between hammerlock 1 and the lock body 3 and device for ejecting also can adopt the structure of conventional cylinder lock.

The use of this pin type theftproof lock is: when it is closed, hammerlock is pressed in the lock body, and under the cooperatively interacting of dead bolt and locked groove, hammerlock and lock body closure; At this moment, under the elastic force effect of jump ring, thumb wheel promotes the core of the card and is stuck in the draw-in groove, and lock body and lock core are fixed.When this lock is opened, key is inserted in the keyhole, on push away key, thimble promotes the thumb wheel handle and moves up, the thumb wheel handle that moves drives thumb wheel and rotates, and the thumb wheel that rotates drives the core of the card and withdraws from draw-in groove like this, makes that lock body and lock core separate, the two can produce displacement mutually; Push away key in the continuation, under the thrust of key, the lock core that separates with lock body move up and on back down and open lever and make and open lever and rotate, the unlatching lever drives connecting rod that rotates withdraws from dead bolt from locked groove, at this moment, under the elastic force effect of opening spring, hammerlock is gone up bullet from lock body, thereby will lock unlatching.
