Description

Lock core preventer

Technical field

This utility model belongs to lockset protective equipment technical field, is specifically related to a kind of lock core preventer.

Background technology

The lock core of lockset exposes the self-evident strong point of lock body and householder can be facilitated to unblank, but also becomes simultaneously and feel the target that unpredictable person's burglary is set about, for instance caused the door unnormal unlocking of locking by so-called MASTERKRY or other instrument insertion lock core.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 in door body and can play effective safety precaution effect to a certain extent for lock core being covered the device (i.e. lock core preventer) protected, and such device is seen in some extent in disclosed Chinese patent literature, typical in Authorization Notice No. CN204418819U " the cover-plate type lock core preventer " recommended, it is the one piece of substrate of position installation in door body and in the front corresponding to lock core, a key resigning hole (patent claims lock core hole) is offered on substrate and in the position corresponding to lock core, a cover plate it is equipped with slidably towards outer side at substrate, this cover plate is coordinated by nut and a lead screw transmission, 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, shifted up from nut drive cover plate that is that coordinate with leading screw and that be arranged on cover plate, make previously to be covered, 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 referring to this patent specification 0018-0020 section).The strong point of this patent of simple in construction system, but protective capacities fragility is its shortcoming.

More typical in Authorization Notice No. CN203947882U " lock pin protecting equipment " provided; this patent formula arranges a header board on lockset; header board is offered a key resigning hole (patent claims lock core hole); header board passes through rotating shaft pivot joint one cover plate and makes the leading flank of cover plate and header board fit; one slide block is on the cover board set; this slide block is slidably matched with the arc chute being opened on header board; at the back side of header board, motor is set; being connected with motor-driven by the rotating shaft of cover plate, the hand-held remote control unit that motor is carried by householder controls.When being sent signal by hand-held remote control unit to control circuit plate, motor is given to instruction by control circuit plate, by driven by motor rotating shaft, cover plate is driven by rotating shaft, slide block on cover plate slides along arcuate groove, make the key resigning hole previously covered by it expose along with moving of cover plate, householder can use key operated door lock, on the contrary same example (specifically can referring to this patent specification the 0017th to 0023 section).This patent formula, except the shortcoming identical with previous patent, there is also following shortcoming: one, owing to needs are using lockset as carrier, thus is easily caused the complication of lockset self structure；Its two, owing to lockset form is different, thus supporting with lockset comparatively bother；Its three, covering to protect not there is enlightening significance the lock core of the existing door lock namely mounted on a door already at the state of use.

For above-mentioned prior art, it is necessary to rational modification in addition, do positive and useful design for this applicant and defined technical scheme described below.
