Abstract
The utility model relates to a safety padlock which belongs to the lockset of hardware tools. The safety padlock comprises a lock body, a lock beam, a lock core, an inner marble, an outer marble, a marble top spring and a key, wherein, a flange and a groove at one side of the top end of the lock core of the padlock are directly switched and matched with a groove and a flange at one end of the lock beam. A cylinder notch is cut from the lower surface of the groove beside the flange of the lock core to the top end of the lock core, and the cross section of the cylinder notch is similar to a bow shape or a jujube-seed shape. Thus, a lock opening mechanism is formed, or the outer margin of the top end of the lock core is bulged and is switched and matched with an annular groove of the lock beam, so the lock opening mechanism is formed. The utility model has the advantages of reasonable structure, simple manufacturing process, raw material saving, low cost, high safety and reliability and good safety performance.
Description
The utility model relates to a kind of Safety padlock, belongs to lockset kind.Lock is one of necessity of human lives, work, study, every household, all trades and professions all be unable to do without it, and lockset is made major contribution for stable, the safety of family of society, the safety of unit, padlock is that output holds pride of place in the production of lockset, has extremely vast market.Currently marketed various padlock is no matter be famous brand, or its lock-opening mechanism of inferior brand all has common structure, the groove fit that one inclined-plane and lock bridge are arranged on Here it is the dead bolt, if apply a vertical force to the dead bolt inclined-plane by the fit clearance between lock bridge and lock body, this power can be decomposed into two component, one along dead bolt inclined-plane parallel direction, an along continuous straight runs, the component of along continuous straight runs can make latch bolt spring shrink, and make the dead bolt along continuous straight runs that displacement be arranged, finally make dead bolt break away from the lock bridge groove, just padlock can be opened without key, very dangerous, this double inclined plane dead bolt of while, complex structure, machining period is many, increases cost, and currently marketed in addition padlock is because interior pellet shot from a slingshot and corresponding pellet shot from a slingshot top spring structure parameter are selected unreasonable, cause and use master key can open padlock, make the safety of lock relatively poor.CN92215757.X padlock at first problem of above-mentioned existence, opens structure to the padlock lock and makes some improvement, directly is fixed with a dihedral abaculus and lock bridge groove fit on the lock core top.This structure obviously overcomes first existing problems, advantage is arranged, but the problem that this technical scheme exists is lock core and dihedral abaculus split processing, manufacturing process is complicated, be fixed on the plane, lock core top as the dihedral abaculus, require the flatness of two contact surfaces processing higher, if fix with Screw, generally will be with two, make a call to two holes, machining screw, assembling and processing trouble, if cooperate processing technology more complicated with dovetail groove, bonding with adhesive, adhesive has certain life-span, is subject to the other factors influence and causes inefficacy, advantage no doubt has, and shortcoming is also a lot of.
The purpose of this utility model is that to design a kind of lock core and lock bridge flange and groove separately that utilize directly chimeric, simple in structure, easy to process, firm and durable, safe and reliable Safety padlock that again can preventing universal key.
The utility model is achieved in that a kind of Safety padlock, comprise lock body, lock bridge, lock core, inside and outside pellet shot from a slingshot, pellet shot from a slingshot top spring, key, the flange and the groove of the lock bridge minor face termination of approximate inverted U directly cooperate with the groove and the flange folding of side, lock core top, show to cut the cylinder breach that a cross section is similar to arc or date core shaped up to the top of lock core to the outside of lock core cylinder key at the groove soffit on lock core flange next door, and mechanism is opened in the locking that constitutes Safety padlock.
In the groove height on the long limit of inverted U lock bridge and the lock body between the side, lock core top a horizontal locking bolt is installed, locking bolt one end contacts with the lock core upper side, and the other end imbeds the inverted U lock bridge to be grown in the groove on limit.Respectively there is a pit lock core side on breach opposite, lock core top at lock bridge groove sustained height.
