Description

Lock core protector

Technical field

The invention belongs to lockset protective equipment technical field, be specifically related to a kind of lock core protector.

Background technology

The self-evident strong point that the lock core of lockset exposes lock body can facilitate householder to unblank, but also become the target felt unpredictable person's burglary and set about simultaneously, such as, insert lock core by so-called MASTERKRY or other instrument and cause the door unnormal unlocking of locking.Statistics according to public security department of China: the approach more than 80% that uninvited guest steals starts from lock core.

Install additional on lock body or on door body and can play effective safety precaution effect to a certain extent for covering the device (i.e. lock core protector) protected to lock core, and such device is seen in some extent in disclosed Chinese patent literature, typically as " the cover-plate type lock core protector " of Authorization Notice No. CN204418819U recommendation, it is on door body and installs one piece of substrate in the position in the front corresponding to lock core, a key resigning hole (patent claims lock core hole) is offered on substrate and corresponding to the position of lock core, a cover plate is equipped slidably in substrate side toward the outside, this cover plate is coordinated with a lead screw transmission by nut, and leading screw is connected with the motor-driven with positive and negative rotating function, the hand-held remote control unit that motor is carried by householder controls.When hand-held remote control unit sends signal to control circuit, motor is given to instruction by control circuit, driven by motor leading screw works counterclockwise, by coordinate with leading screw and the nut be arranged on cover plate drives cover plate to top offset, make previously to cover by cover plate the key resigning hole protected to expose, householder just can insert lock core opening door lock with key, and vice versa (specifically can see the manual 0018-0020 section of this patent).The strong point of this patent of structure Simple System, but protective capacities fragility is its shortcoming.

More typical " lock pin protecting equipment " provided as Authorization Notice No. CN203947882U; this patent formula arranges a header board on lockset; header board is offered a key resigning hole (patent claims lock core hole); header board make the leading flank of cover plate and header board fit by axis of rotation pivot joint one cover plate; one slide block is on the cover board set; this slide block and the arc chute be opened on header board are slidably matched; at the back side of header board, motor is set; be connected with motor-driven by the axis of rotation of cover plate, the hand-held remote control unit that motor is carried by householder controls.When sending signal by hand-held remote control unit to control circuit board, motor is given to instruction by control circuit board, by driven by motor axis of rotation, cover plate is driven by axis of rotation, slide block on cover plate slides along deep-slotted chip breaker, make the key resigning hole previously covered by it expose along with moving of cover plate, householder can use key operated door lock, otherwise with example (specifically can see the 0017 to 0023 section, the manual of this patent).Except the shortcoming identical with last patent, also there is following shortcoming: one, because needs are using lockset as carrier, thus easily causes the complicated of lockset self structure in this patent formula; Its two, because lockset form is different, thus supportingly with lockset comparatively to bother; Its three, to existing be in using state be namely arranged on covering to protect and not there is enlightening significance of the lock core of the door lock on door.

For above-mentioned prior art, be necessary rational modification in addition, the applicant has done positive and useful design and has defined technical scheme described below for this reason.
