Description
Affiliated technical field:
The utility model relates to a kind of unlatching Lock Protective Device of door lock, can protect especially that lock body is disclosed out or drilled back and make the tapered end protecting cover of the door lock that the safeguard function of door lock lost efficacy.
Background technology:
Door lock is to be used at home, and office or other communal facility are as a key factor of preventive means, and the lock function quality of door lock is directly connected to people at home, office, the property of communal facility and personal safety.Just because of door lock is to modern's importance, so done a large amount of work and innovation aspect the reliability after the lock function of door lock and locking, the mechanical type monodirectional locking, the appearance of new technologies such as the electronics of multidirectional locking of structural formula and high-tech or combination type locking and come into operation after, the safeguard function of door lock is greatly improved, has ensured people's property and personal safety to greatest extent.But the use of these new technologies is from beginning to today, use any lock mode no matter be, they all have a common feature, the unlatching tapered end of lock body exposes on the door surface, the safeguard function effect of door lock is just had a greatly reduced quality, the probability that door lock is disclosed out or bored out increases, and lose and the personal safety of property encroached on has just become thing sooner or later.The tapered end safeguard procedures of this present situation and door lock are still like this, and potential safety hazard exists.
Summary of the invention:
For the tapered end that overcomes existing door lock exposes the deficiency that exists aspect the surface of door and the tapered end safeguard function difference because of design, the utility model provides a kind of tapered end protecting cover of door lock, the tapered end protecting cover of this door lock can not only cover the tapered end of door lock fully, and can lock protecting cover and prevent that lock body from not encroached on.
The technical scheme that its technical problem that solves the utility model adopts is: structurally, protecting cover seat, junction plate are fixed by bolts on the panel of door, and protecting cover is installed on the protecting cover seat one side free bearing with bearing pin.Three directions of protecting cover are provided with built-in threaded screw rod, and the trend of threaded screw rod front and back displacement in protecting cover is just predefined according to screw thread, and the rotating nut that is provided with on the protecting cover is stirred in anti-silk decision, and threaded screw rod is displacement forward or backward, locking or unlatching protecting cover.When door lock need be opened, at first stir nut on the protecting cover respectively by predefined screw thread trend, make threaded screw rod towards the opening direction displacement, break away from protecting cover seat lockhole, open protecting cover then, insert the key operated door lock of door lock.When door need be closed locking, press protecting cover, difference rotating nut, threaded screw rod insert in the protecting cover seat lockhole, and protecting cover is locked, and the tapered end of lock body is covered fully, and tapered end has obtained protection, and locking is reliable.
The beneficial effects of the utility model are to have improved the safeguard function of door lock when the tapered end that covers door lock is not fully encroached on.
