Abstract

The utility model relates to a safety lock that is against pulling, filling and drilling. A supporting board is provided with an outer lock body; the lock core is sleeved in the outer lock body, and the outer lock body is provided with billiards, springs, elastic locking pieces and turning pulling pieces which compose a lock core mechanism; the center of the lock core is provided with a centering column, the diameter of which is just the inner diameter of a hollow key; the lower part of the lock core is a ring groove; and the other side of the ring groove is provided with billiards and springs institutions; the rigid lock shell is buckled on the lock core mechanism; the center is provided with a key location hole, and the direction of the key location hole is contrary to the assembly hole of the billiards and the springs; a centering column on the lock core body is enchased in the central part of the jack for the key to lock shell; between the two bodies, the space for inserting the hollow key is kept. The structure with billiards and springs arranged in the opposite direction of keyhole may effectively prevent from being dispersed, plugged or the watering damage to lock core, playing a role of anti-pulling, anti-plugging, and against-drilling. The utility model is characterized in that the structure is simple; the process is convenient; the price is low; and the use is safe. The utility model can be widely applied to door locks, cabinet locks and auto-locks, etc.

Description

Anti-group, antifouling, anti-drilling safety lock

Technical field

The utility model relates to the improvement to existing institute tool, discloses a kind of anti-group, antifouling, anti-drilling safety lock, belongs to the mechanical lock technical field.

Background technology

Existing lockset comprises padlock, built-in lock etc., because its lock core, lockhole, pellet shot from a slingshot all are exposed to outside the lock body, therefore, so-called MASTERKRY is easy to open it, electric drill also can directly bore the lock core outside the lock body thoroughly lockset is destroyed, perhaps lockhole is stopped up by foreign material such as thin rod, glue easily, and lockset is destroyed, and greatly reduces the safety of lockset.

Summary of the invention

The utility model discloses a kind of anti-group, antifouling, anti-drilling safety lock, and the mechanisms such as lock core that solved existing lockset are exposed to the shortcoming that lock body causes outward.

Technical solution of the present utility model is as follows: lock body outside being provided with on gripper shoe, in the outer lock body of plug body suit and be equipped with pellet shot from a slingshot, spring, spring locking plate and turn to plectrum to constitute lock core mechanism, it is characterized in that: the SMIS in plug body is provided with the centering post, diameter is the internal diameter of hollow key, the bottom is a ring shaped slot, the opposite side of ring shaped slot is provided with pellet shot from a slingshot, spring mechanism, the lock housing of rigidity is buckled in the lock core mechanism, the centre of lock housing is provided with the key positioner hole, the direction in key positioner hole and pellet shot from a slingshot, the spring pilot hole is opposite, the stem stem of deciding on the plug body is embedded on the center of lock housing key hole, leaves hollow key between two bodies and inserts the gap.

When hollow key inserts plug body from the key positioner hole of lock housing, be introduced in the ring groove of plug body, could be connected with pellet shot from a slingshot, spring and outer lock body after rotating to an angle, constitute unlocking mechanism, open lockset, therefore, after so-called MASTERKRY is gone into from the key positioner hole slot, can't push the pellet shot from a slingshot and the spring mechanism of plug body opposite side, the lockset of not opening has played anti-effect of dialling.

Because the corresponding key positioner of plug body hole site is a ring shaped slot, rather than pellet shot from a slingshot, spring mechanism, so foreign material such as the fiery material rod that inserts from the key positioner hole, glue, can only enter into ring shaped slot, all do not contact pellet shot from a slingshot, spring mechanism, destroy so can not constitute, cooperate the lock housing of rigidity to make the utility model reach the purpose of anti-clogging and anti-electric drill lock core mechanism.

Good effect of the present utility model is: on existing lockset, the plug body external diameter is strengthened, adopt pellet shot from a slingshot, spring mechanism to be located at the opposite direction structure of keyhole, can effectively prevent to push aside, stop up or water and destroy the lock core behavior, played anti-group, antifouling, anti-drilling safety effect; The utility model is simple in structure, and production and processing is convenient, and cost price is cheap, and is safe and reliable, makes the lockset of same level improve class, can be widely used in locks such as door lock, cabinet lock and automobile and prohibit in the mechanism.
