Description

Ground lock for metal winding door

The utility model relates to a kind of lockset, particularly a kind of door lock that is used for sealed rewindable metal curtain door.

The street door of shop, bank etc. and the door in some other important place generally all are equipped with metal rolling door to increase anti-theft security, mostly present sealed rolling door is common padlock or steel wire lock if being used, whole lockset is unsettled, exposed after the sealed rolling door of this class lockset, characteristics of this body structure of lockset in addition, adopt means such as saw, cut, pound to be easy to lockset is destroyed the rolling door unlatching, thereby be absolutely unsafe.

The purpose of this utility model provides powerful, the sealed rear defence of a kind of lockset degree and saws, cuts, pounds and be difficult for lockset is destroyed, strong security, and the rewindable metal curtain ground that is difficult for being unlocked locks.

Rewindable metal curtain door ground lock is made of tapered end, latch fitting, lock, tapered end by lock body, be loaded on the lock core that has tumbler lock mechanism in the lock body, dial the lock pin of passing moving and lock in place by lock core and constitute, have latch fitting to insert cavity on the lock body, the lock pin locking-up end can be stretched in the cavity by the cavity side walls face.Latch fitting one end has the lock pin patchhole, and contiguous other end place is neck shin structure and the block shoulder is arranged.Lock is one to have the hollow object in core chamber, and one port has the shutoff that has the latch fitting patchhole that adapts with the latch fitting cross section, have on its outside wall surface anti-skidding stupefied, to prevent to deviate from after lock from imbedding ground.

In order to increase the safety and the confidentiality of rewindable metal curtain door ground lock, it further improves is the axial cylinder groove that the lock core core retainer plate of tapered end has four mutual vertical distribution, in shoot son and constitute four tumbler lock mechanisms, the tapered end key hole is a cross.

When rewindable metal curtain door ground lock uses tapered end is loaded on the rolling door, lock is imbedded ground and fixing with the compo cast.Insert latch fitting in the lock when sealed and rotate an angle latch fitting block is connected on the lock, the latch fitting that the rolling door of leaving behind makes the latch fitting end insert tapered end insert rotational lock core in the cavity make lock pin stretch in the cavity and the lock pin jack internal lock lock pin that inserts the latch fitting end to be about to rolling door sealed.

Rewindable metal curtain door ground lock is with the sealed back of rolling door tapered end ground proximity, and the tapered end lock body is that monoblock cast forms, and intensity is difficult for greatly being smashed, and has protected lock core not to be destroyed effectively.Tapered end ground proximity, latch fitting exposed parts are seldom opened or are destroyed so be difficult to will lock with means such as sawing, cut.Tapered end has four tumbler lock mechanisms, and polarization is strong, and keyhole is a cross, the key of unblanking is four stupefied teeth shapes, key inserts in the tapered end and must correspondingly one by one lock could be opened, thus adopt other alternatives to be difficult for locking unlatching, thereby safety is reliable, strong security.

Accompanying drawing is an embodiment of the present utility model, below structure embodiment further specify the utility model.
