Pick-proof lock

The utility model belongs to a kind of pick-proof lock

At present, 2/3rds position below the lock body of common padlock just is used for installing the lock SMIS and the decorative pearl on top of an official cap, and inoperative to the fastness of lock, dead bolt ejects by spring, and is shaky, is easy to pry open.Patent 89209119.3 pick-proof padlocks, patent 91233303.0 theft proof padlocks, structure are complicated, and the pick-proof performance is good inadequately, waste material, and cost is higher.

It is a kind of simple in structure, easy to make that the purpose of this utility model is to provide, economical with materials, the pick-proof lock that the pick-proof performance is good.

The utility model is made up of lock body, iron hoop, core, little axle, spring, pin.In the lock body (1) lock core (3) is housed, back-moving spring (5) and pin (6), back-moving spring (5) is contained on the breach of lock core (3), on another breach of lock core (3) pin (6) is housed, lock body (1) top fluting, the bipod of iron hoop (2) inserts in the groove of lock body (1), one pin is hinged with lock body (1) by little axle (4), another pin fluted (8), replace dead bolt with lock core (3), during locking, lock core (3) traverses the groove (8) that passes iron hoop (2), lock core (3) has been cut groove (7 with iron hoop (2) two pin appropriate sections, 11), when lock core (3) turns over an angle, groove (7) is relative with iron hoop (2) bipod respectively with groove (11), the rotatable pin of iron hoop (2) is extracted lock body (1) out, iron hoop (2) one pin also can not be provided with little axle (4), be stuck in lock body (1) but interior horizontal direction rotation, replace vertical direction to rotate, another pin of iron hoop (2) has projection (9), and have groove (8), lock body (1) corresponding site has T-slot (10), and it is fluted that lock ring is fixed the relative lock core of an end, the relative iron hoop of lock core position is fluted, the fixing end of iron hoop also can be contained in lock core (3) above.

The utility model is simple in structure, saves some parts, makes easy to makely, and man-hour is few.This lock is very firm, is difficult for prying open, and the lock health is long-pending little, lock laborsavingly, and cost is low, is subject to user's welcome.
