There is spring, dead bolt auto-extending lock body in the presence of the spring, elastic hook is installed on lock body, elastic hook is shaped such that
Elastic hook can hook dead bolt under natural resiliency effect, and and can is enough to break off relations when being touched with dead bolt, and elastic hook is in lock body
On installation site so that after dead bolt is retracted lock body, elastic hook just hooks dead bolt, prevents dead bolt resilience from stretching out lock body, and
And when dead bolt reaches the position relative with lockhole with the closing motion of lock body mounting object, elastic hook is just pacified by lockhole
Dress object is touched so that being broken off relations with dead bolt.
As preferred forms, the elastic hook is one piece of spring leaf, and its one end is fixed in lock body, and the other end stretches out
Outside lock body.
The method have the benefit that the dead bolt retraction lock body after unlocking is hooked by elastic hook, dead bolt will not return
Bullet stretches out lock body, and therefore, when the lock body mounting object such as closing the doors and windows, dead bolt will not be with the lockhole mounting object such as doorframe, window frame
Collide, once and elastic hook encounter the lockhole mounting object such as doorframe, window frame, elastic hook will break off relations with dead bolt immediately,
Make dead bolt resilience and insert in lockhole, be automatically performed action of locking.Due to when the lock body mounting object such as closing the doors and windows, without logical
The inclined-plane of collision dead bolt is crossed to force dead bolt to be retracted lock body, therefore greatly reduces making an uproar when the lock body mounting object such as closing the doors and windows
Sound, extend the service life of whole lockset and lock body mounting object.On the other hand, reduce and power is exported to automatic door closer
Requirement, automatic door closer is made more compact, be advantageous to the lightweight of automatic door closer.Furthermore due to without by touching
The inclined-plane of spring lock tongue forces dead bolt to be retracted lock body, it is therefore not necessary to process inclined-plane for dead bolt, advantageously reduces whole lockset
Manufacturing cost.
