Description
Technical field
It the utility model is related to a kind of lock body.
Background technology
At present, the lock body that in the market provides generally comprises lock housing, lock core and the dead bolt that can pass lock housing, and lock core, which is provided with, to be dialled
Block, key insertion lock core simultaneously rotate shifting block, and shifting block coordinates with dead bolt makes dead bolt stretch out lock housing or retraction lock housing, unlocked with to reach or
The purpose of locking, this lock body security is poor, easily stolen, and dead bolt does not have locking device yet, and structural stability is not good enough.
The content of the invention
In view of the deficiency of background technology, it is more preferable that technical problem to be solved in the utility model is to provide a kind of theftproof performance
And the lock body that structure is more stable.
Therefore, the utility model is adopted the following technical scheme that to realize：
A kind of lock body, including lock housing, lock core and the dead bolt that can pass lock housing, the lock core are provided with shifting block, it is characterized in that：
Be provided with the first bearing pin in the lock housing, the dead bolt is provided with the horizontal strip through-hole with the cooperation of the first bearing pin, in the dead bolt
Side lower end is provided with three locked grooves that can hold shifting block insertion, and locking device is additionally provided with the dead bolt.
The locking device includes closing piece and elastic component, and the lock housing is provided with the second bearing pin, the closing piece be provided with
The first longitudinal direction strip through-hole that first bearing pin coordinates, the second longitudinal direction strip through-hole coordinated with the second bearing pin is additionally provided with closing piece,
The elastic component is arranged in lock housing by bolt, and elastic component one end is against on lock-shell lining, the other end is against closing piece upper end,
The dead bolt inner top side is provided with multiple necks, and the closing piece is provided with the fixture block of multiple pluggable necks.
The closing piece lower end has the curved surface coordinated with shifting block.
The elastic component is torsion spring.
After adopting the above technical scheme, dead bolt is provided with three coordinates locked groove with shifting block, key is inserted rotatable three after lock core
Circle, realizes triple lock functions, and theftproof performance is more preferable, and must insert the key of matching in lock core and turn during open locking
Dynamic, closing piece, which first moves up, makes fixture block depart from neck, and shifting block could drive dead bolt to move, and the downward reset of closing piece then has torsion spring
Torsion provides, and the setting of locking device makes lock body structure more stable and further enhances the anti-theft of lock body.
