Description

Hidden anti-theft lock and key thereof

Technical field

The utility model is a kind of improved antitheft sylinder, belongs to the cylinder lock field.

Background technology

Common spring lock (containing other many row's cylinder locks) when opening owing to outside the lock pellet shot from a slingshot is exposed to fully, is easy to quilt cover and opens.Modern society presses for better, the inexpensive again novel lockset of safety and reliability of theftproof performance.Though electronic cipher lockset and IC-card lockset security performance height thereof, but because the integrity problem of electronic device, the electric lockset that still needs a top grade also is difficult to avoid one " weakness ", solves the antitheft of lock, is the major issue that ensures social family's property safety.

The utility model content

The purpose of this utility model provides a kind of improved antitheft sylinder, and this lockset can not be by pirate of the open.

The utility model adopts a kind of lock core by the hidden anti-theft lock of concealed installation in lock body inside, it includes lock body, lock core, lock tube, locking closure, locking closure cap and lock pellet shot from a slingshot, marble spring, it is characterized in that: the key of the utility model lockset is opened the side at lock body, its lock core is by the central inner of concealed installation at lock body, the pellet shot from a slingshot hole that a plurality of perforations are arranged on the lock core, every group of pellet shot from a slingshot is by key pins, 3 kinds of pellets shot from a slingshot of lock core marble and lock spring are formed, lock body outer anterior also have locking closure and locking closure cap, its locking closure is the high duty metal plectane of a straw hat shape, it is also free to rotate by the front end that the locking closure cap of ring-type is encapsulated in lock body, the corresponding lock body key of locking closure one side place has one can insert the key breach that key is used, the lock core front end has the lock core platform of " one " font, the locking closure middle inside has a groove, and groove is enclosed within on the platform of lock core and is slightly larger than the lock core platform.Key of the present utility model, its key bit are inverted T-shaped, and the key teeth groove is opened the standing portion at key, and key part and key bit part in vertical state.

Lockset of the present utility model is hidden in the locking closure owing to its rotary locking cylinder, key is inserted in the fixedly key on the lock body, make the groove in the locking closure drive the lock core rotation by the rotation locking closure, in opening process, keyhole and key bit are sheltered from owing to the locking closure hole is rotated, crooked key has also stopped the passage that cover is unblanked, the lock that this employing indirect mode is promptly opened by the rotation locking closure, the lock pellet shot from a slingshot is hidden in the locking closure in opening process fully, thereby can avoid quilt cover to open, make this product have high anti-theft feature.Because it still belongs to mechanical cylinder lock, so have anti-strong jamming, anti-strong magnetic destruction, no circuit, power supply hidden danger, characteristics simple in structure, safe and reliable.

Description of drawings:

Accompanying drawing is a structural representation of the present utility model, wherein

Fig. 1 is a sectional view of the present utility model;

Fig. 2 is a right view of the present utility model;

Fig. 3 is a locking closure left view of the present utility model.

Embodiment:

Among the above figure, 1-locking closure wherein, 2-locking closure cap, 3-locking closure keyhole, 4-lock core platform, 5-lock tube, 6-lock body, 7-key, 8-lock core, 9-dish groove, 10-spring, 11-key pins, 12-lock core marble, 13-lock spring, 14-tailgate, 15-key.

The utility model is achieved like this: center in a lock cylinder (6), the lock core (8) that a front end has the cylindrical shape of a lock core lock core platform (4) is installed, and key (7) is open at lock body one side (as the lower end) and on the non-traditional rotary locking cylinder; Front end at lock body and lock core also has a locking closure cap (2), the tight pressing of locking closure cap and lock body, and a cavity is arranged in the locking closure cap, one locking closure (1) free to rotate is arranged in the cavity, locking closure has a groove (9) (seeing figure three) by cylinder side, and it is last and more bigger than platform (4) that the groove correspondence is buckled in lock core platform (4); Key (15) is inserted in the fixing key (7) of lock body and can not rotates, the key that is complementary can make the two ends of the pellet shot from a slingshot (12) in the lock core (8) be in the bite with lock body, at the rotation locking closure and when locking closure keyhole (3) has departed from key notch (7) substantially, dish-shaped groove (9) in the locking closure can make lock core rotate, indirect the finishing of tailgate (14) drive lockset by the lock core rear portion unblanked, when the key that nothing is complementary, lock core marble (12) two ends are not in bite owing to the effect of lock spring and marble spring (14), promptly can't finish unlocking function, when overlapping out cylinder lock set, need two preconditions: 1).Pellet shot from a slingshot can touch, visible so that implement the cover work that goes into operation; 2).Lock core can be rotated, to finish the lock set action; And locking closure keyhole of the present utility model (3) when not blocking key notch (7) (seeing figure two) satisfied condition 1, can't satisfy condition 2, having satisfied condition 2[when locking closure keyhole (3) departs from key notch (7) at this moment rigidly connects and contacts lock core platform (4) in locking closure groove limit, if pellet shot from a slingshot coincide, can drive the lock core rotation] can't satisfy condition 1 again, therefore, when the key that is not complementary, adopting cover to open method is powerless to the utility model lockset.The utility model has solved traditional cylinder lock set easily by the technical barrier of pirate of the open.

The key (15) that the utility model uses is also inequality with traditional key, and its key bit is an inverted T-shaped, and the key teeth groove is opened the standing portion at key, and key part and key bit part in vertical state.In use, lock handle is partly stayed locking closure keyhole (3) in addition, and key bit is blocked by locking closure keyhole (3), and key need not rotate, and finishes breakdown action by the rotation locking closure.
