Abstract

A Y-shaped key lock comprises a lock outer sheath and a lock core and is characterized in that the section of a key jack on the lock core is Y-shaped, and the section of the key matching with the key jack is also Y-shaped. The widths of three slots forming the Y-shaped key jack can be same or different. The angles between the three slots on the key jack can be equal or unequal. The lock has the advantages of a simper structure, lower cost, low simultaneous unlocking rate among locks; therefore, the lock is in particular applicable to the locks for anti-theft lockset of door lock, strongbox lock or bicycle lock.

Description

Y shape key lock

The utility model belongs to lock technology field, particularly a kind of mechanical type Y shape key lock.

Now there are two kinds of in-line and crosss in the cross section of the key hole on its tapered end of mechanical lock on the market, and the corresponding key of unblanking is in-line key and cross key.Wherein, the in-line key lock exists the same higher weak point of rate of opening between lock and the lock; It is complicated that the cross key lock exists structure, the weak point that cost of production is higher.In addition, because the type of mechanical lock only has in-line key lock and cross key lock, so it is higher to open rate mechanical lockset same generally.

Task of the present utility model is at prior mechanical in-line key lock and the existing above-mentioned weak point of cross key lock, provide that a kind of structure is simple, cost is lower, the cross section of key is different from the Y shape key lock of existing in-line key and cross key.

Task of the present utility model is finished as follows: Y shape key lock comprises tapered end overcoat and lock core, the cross section that wherein is located at the key hole on the lock core is a Y shape, its cross section of key of matching with this key hole also is Y shape, the width of forming 3 slots of Y shape key hole can be identical or have nothing in common with each other, outside tapered end, put and have 3 row's pellet shot from a slingshot holes of matching with 3 slots on the key hole, in each pellet shot from a slingshot hole, be provided with successively down pellet shot from a slingshot, on pellet shot from a slingshot, spring and end socket.As required, 3 slots angle each other on the key hole can be that equate or unequal.

The utility model Y shape key lock is compared with the cross key lock with prior mechanical in-line key lock, have that structure is simple, cost is lower, the same low characteristics of rate of opening between lock and the lock, the utility model is particularly suitable as the tapered end of antitheft class locksets such as door lock, Safe lock, bicycle lock.
