The utility model has the benefits that the anti-theft performance is enhanced, and the mutual unlocking rate is reduced.
Description
Technical field
The utility model belongs to the technical field of the lock of anti-technical opening, is specifically related to a kind of anti-theft lock.
Background technology
Existing tapered end mainly comprises overcoat, inner core, key, hoodle group and spring, overcoat entangles inner core, the hoodle group is arranged between overcoat and the inner core, after inserting key, tooth on the key maintains an equal level every group of decorative pearl on top of an official cap outer face and inner core outer cylinder in the hoodle group, and inner core can and be unblanked with respect to the overcoat rotation, after extracting key out, flat pearl is stuck in the front portion that the decorative pearl on top of an official cap heads into inner core and flat pearl between overcoat and the inner core, and inner core can not be relative to rotating with overcoat, thereby can not unblank.The shortcoming of this lock core is that theftproof performance is low, is easy to lock be opened with the mode of choosing pearl by the lawless person.Though the protective equipment of the pick-proof of lockset, imitative brill, protecting against shock is very perfect in the prior art, and is still not ideal enough in the performance of antitheft anti-technical opening and the control of mutual opening rate.
The utility model content
At problems of the prior art, the purpose of this utility model is to provide a kind of shield anti-theft lock.
To achieve these goals, technical solution adopted in the utility model is:
A kind of shield anti-theft lock, comprise lock housing, in the cavity that the lock housing both sides are provided with respectively socket the lock core of band key hole is set, about the lock housing of key hole top one group of through hole is set respectively, through hole sets gradually pellet shot from a slingshot, anti-pellet shot from a slingshot, the spring silk dialled from the inside to the outside, the key hole below is provided with steel disc, key hole the inner, the left and right sides is equipped with trace, be equipped with thumb wheel between two cavitys of lock housing, the jack below is provided with the pick-proof sheet, and be provided with on the key and the corresponding transverse concave groove of pick-proof sheet, pellet shot from a slingshot is double;
The top of spring silk is provided with pellet shot from a slingshot on several;
The most inboard one group of pellet shot from a slingshot about lock housing, anti-ly dial that clamping is provided with steel ball between the pellet shot from a slingshot;
The thumb wheel that is equipped with between described lock housing two cavitys by about the card and the lock core card that are equipped with switch through movingly;
The lock-shell lining below is provided with groove, and steel disc cooperates with the lock housing clamping by groove;
Be equipped with steel sheet spring between steel disc two ends and the lock core, be equipped with the blade marble spring between pick-proof sheet one end and the lock housing;
Cushion block is set key hole the inner, the left side and trace is connected;
The bottom of pick-proof sheet is provided with groove, and the groove on each pick-proof sheet is differential to the distance at pick-proof sheet center to be 0.5mm.
The beneficial effects of the utility model: on the basis of original pellet shot from a slingshot, increase pick-proof sheet and corresponding on the key transverse concave groove, the key of other different sizes or stealing tool just can't inject lockhole, reach the technical purpose that can not open, can play antitheft effect, several pellets shot from a slingshot that the back side of lock core is provided with can reduce mutual opening rate.
