Abstract
The utility model relates to a theftproof lock head which belongs to the technical field of a technical unlocking resisting theftproof lock. The theftproof lock head comprises a lock shell, cavities which are arranged on both sides of the lock shell are respectively sheathed with a lock core with a key jack, the left and the right of the lock shell above the key jack are respectively provided with a group of through holes, each through hole is orderly provided with marbles, pull-resisting marbles and spring wires from inside to outside, the top of each through hole is matched and provided with an elastic cover, blade marbles and steel pieces are orderly arranged under the key jack, linking rods are arranged on the inner ends of the left and right key jacks, and a pull wheel is arranged between the two cavities of the lock shell. The technical proposal is adopted, when a lock is unlocked, the common marbles and the blade marbles are pushed to an unlocking position at the same time to unlock the lock; if a lawless person uses a steel needle, and the like to pick the marbles, the common marbles which are arranged on the upper part can be technically unlocked, but the lock can not be unlocked in respect that the steel pieces are still clamped between the lock body and the lock core at the moment. The utility model can effectively prevent a technical person from unlocking the lock, and consequently, the purpose for stopping the technical unlocking is achieved, and the theftproof performance of the lock is increased.
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 end.
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, only by lock being opened with the mode of choosing pearl by the lawless person easily.Though the protective equipment of the pick-proof of lockset, imitative brill, protecting against shock is very perfect in the prior art, the performance of antitheft anti-technical opening still is not ideal enough.
The utility model content
At problems of the prior art, the purpose of this utility model is to provide a kind of technical scheme of anti-theft lock end, increases special-shaped blade marble and steel disc on the basis of original pellet shot from a slingshot, strengthens theftproof, stops technical opening.
Described anti-theft lock end, comprise lock housing, it is characterized in that in the cavity that the lock housing both sides are provided with that socket respectively is provided with the lock core of band key hole, 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, and the top of through hole is equipped with the bullet lid, and the key hole below sets gradually blade marble, steel disc, key hole the inner, the left and right sides is equipped with trace, is equipped with thumb wheel between two cavitys of lock housing.
Described anti-theft lock end is characterized in that clamping is provided with steel ball between one group of the most inboard about lock housing pellet shot from a slingshot, the anti-group pellet shot from a slingshot.
Described anti-theft lock end, it is characterized in that 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.
Described anti-theft lock end is characterized in that the lock-shell lining below is provided with groove, and steel disc cooperates with the lock housing clamping by groove.
Described anti-theft lock end is characterized in that being equipped with steel sheet spring between steel disc two ends and the lock core, is equipped with the blade marble spring between blade marble one end and the lock housing.
Described anti-theft lock end is characterized in that key hole the inner, the left side is provided with cushion block and trace is connected.
Described anti-theft lock end is characterized in that the bottom of blade marble is provided with groove, and the groove on each blade marble is differential to the distance at blade marble center to be 0.5mm.
Adopt the technical solution of the utility model, when unblanking, lock could be opened when must be simultaneously shifting common spring and blade marble onto lockset position of coupler simultaneously, if the lawless person chooses pearl with instruments such as draw points, technical opening the common spring that is provided with above also lock can't be opened because this moment, steel disc also was stuck between lock body and the lock core.The utility model is simple and reasonable for structure, and practicality is stronger, can prevent effectively that the technician from opening lock, thereby reach the purpose of stopping technology unlocking, has improved the theftproof performance of lock.
