Summary of the invention
The purpose of this utility model is at above-mentioned existing problems and deficiency; provide a kind of and both can avoid effectively that lock core is contaminated, corrosion and the generation of phenomenon such as filled in by foreign matter, and the safe-guard door lock of the core over cap with lock of simple in structure again, easy to use, good looking appearance.
The technical solution of the utility model is achieved in that
The safe-guard door lock of core over cap with lock described in the utility model; comprise lock gall and lock body; wherein; described lock body comprises lock tube and is installed on lock, lock core and lid on this lock tube and places lock core over cap on the described lock external surface; the outer end that is characterized in described lock stretches out in described lock tube external surface slightly; described lock core is installed on the described lock on one side prejudicially towards described lock, and described lock core over cap is installed on rotating shaft on the described lock another side and rotatable being slidably connected on the described lock by one.
And be further to strengthen its reliability of structure; and simple and easy, the good looking appearance of its processing; it is the arc closing in chute at center with described rotating shaft that the inner surface of above-mentioned lock core over cap is provided with one; correspondingly be provided with a joint pin that can be flush-mounted in the described closing in chute on the described lock, described lock core over cap is set with cooperating of described arc chute by described rotating shaft and described joint pin and is connected on the above-mentioned lock.For further strengthening its reliability of structure, be connected with torsion spring or shell fragment on the inner end of above-mentioned joint pin or rotating shaft.
It is more convenient for the utility model is used, returning apparatus has the fingerprint unlocking apparatus in above-mentioned lock gall and the lock body, and this fingerprint unlocking apparatus comprises the fingerprint recognition control device that is installed on the above-mentioned lock tube and is installed on the interior fingerprint transmission device that be electrically connected with described fingerprint recognition control device and that can drive described lock gall internal lock tonguing row stretching motion of above-mentioned lock gall.
The utility model owing to adopt is installed on lock core prejudicially on the lock of lock body and the lock core over cap is connected in structure on the lock by a rotating shaft that is installed on the lock another side; make the utility model in the process of using; both can make lock core have disguise by the effect of lock core over cap and prevented effectively that the keyhole on the lock core from the generation of incident such as filling in by outside contamination or by foreign matter, strengthen the safety of its use simultaneously again.And when unblanking,, be at this moment available key operated or locked door lock, so extremely easy to use as long as like a cork the lock core over cap is removed to a sideway swivel keyhole is exposed.And because the utility model also adopts the structure that inner surface is provided with arc closing in chute and corresponding setting is flush-mounted in the joint pin in the chute on lock at the lock core over cap; both further strengthened its reliability of structure; the monnolithic case that does not influence lock body again is attractive in appearance; and simple in structure, cost of production is low, so the utility model can be widely used on the various security doors.
Below in conjunction with accompanying drawing the utility model is further described.
