Abstract

The invention relates to a protection safety device of an anti-theft door lock cylinder, comprising a direct current motor, a speed changer, a threaded shaft, a nut, a moving sealing plate, a shell, a battery and a control circuit board, wherein the nut is fixed on the back surface of the upper end of the moving sealing plate; the direct current is directly connected with the speed changer; the threaded shaft is used as an output shaft of the speed changer; the direct current motor, the speed changer, a power switch, the battery, the control circuit board and a limit switch are all arranged on the shell; the limit switch corresponds to the upper edge of the moving sealing plate; the shell is fixed on the panel of the anti-theft door; the lock cylinder is arranged in a window of the shell; and the motor, the power switch, the control circuit board and the limit switch are connected in series and then connected with the battery. After people leave the home, the lock cylinder is shaded by the moving sealing plate, i.e. a safety protection lock cover which has a password and is opened by remotely controlling is installed for the lock cylinder of the anti-theft door, so that the lock cylinder cannot be contacted by thieves and naughty children, thus the thieves cannot open the lock by a technical means, and the naughty children cannot plug the lock cylinder hole with a toothpick and an iron wire.

Description

The protection safety device of anti-theft door lock cylinder

Technical field:

The present invention relates to the anti-theft door lock cylinder protective device.

Background technology:

At present, on the steel plate punch forming security door that the ordinarily resident generally uses, all comprise lockset, handle, opal and door body, though this class security door can play certain antitheft effect, but also there is deficiency in the lockset aspect, for example the lockhole of most security doors all is exposed, this opens door lock just for thief's application technique means convenience is provided, because some thief can use the multiple technologies means to open the door lock of security door easily, burglary causes material and spiritual dual loss for numerous residents; On the other hand,, very easily stopped up lockhole with toothpick, iron wire etc., cause many inconvenience to resident family by the playboy because lock core is exposed outside.

Summary of the invention:

In order to overcome the exposed many deficiencies that caused outside of open keyhole, the invention provides a kind of protection safety device of anti-theft door lock cylinder, it can well overcome above-mentioned defective.

The protection safety device of described anti-theft door lock cylinder, comprise direct current generator, speed changer, thread spindle, nut, mobile hush panel, housing, battery and control circuit board, described housing comprises window, switch cavity, motor cavity, side panel, outer panel, battery cavities and control assembly chamber, side panel and outer panel form sliding tray, mobile hush panel is positioned at sliding tray, nut is fixed on the back side of mobile hush panel upper end, direct current generator and speed changer direct connection, thread spindle is the output shaft of speed changer, the conjunction of direct current generator and speed changer is installed in the motor cavity, thread spindle and nut are on the same straight line, power switch is installed in the switch cavity, battery is installed in the battery cavities, control circuit board is installed in the control assembly chamber, limit switch is installed in the motor cavity, limit switch is corresponding with the top of mobile hush panel, housing is fixed on the Theft-proof Door Panel by four fastening screws fixed thereon, lock core is arranged in the window of housing, direct current generator, power switch, control circuit board is connected with battery with limit switch series connection back.

Its course of work is as follows:

(1), closes and close the safe-guard door lock safety guard

Press power switch on the other hand, entire circuit is connected, the direct current generator drive speed transmission is just changeed, thread spindle just changes synchronously, another hand is upwards put forward mobile hush panel, be fixed on nut on the mobile hush panel back side with after thread spindle contacts, thread spindle promptly screws in the nut, slowly rise thereby drive mobile hush panel, when the top of mobile hush panel touched limit switch, entire circuit was cut off the power supply automatically, motor quits work immediately, unclamp power switch, mobile hush panel promptly is in closure state, and lock core is moved hush panel and blocks.

(2), open the safe-guard door lock safety guard:

Pin the fixed power source switch on the other hand, another hand is pinned the remote controller switch, circuit is switched on after signal is opened in the reception of transmission signaling switch signal in the control circuit board, the counter-rotating of direct current generator drive speed transmission, and thread spindle reverses synchronously, nut drives mobile hush panel and moves down, after nut broke away from thread spindle, the sliding tray of the conjunction of nut and mobile hush panel on the housing of deadweight condition lower edge fell automatically, exposes anti-theft door lock cylinder, unclamp power switch, promptly available key is opened lock.

(3), indoorly open the door, lock and the insurance method

Indoor open the door, lock, the insurance method is identical with existing method.

Because the present invention has been set up in the lock core position at existing security door, after the head of a family gos out, lock core is moved hush panel and blocks, a security protection lock cover that the band cipher remote control is opened has been installed promptly for the lock core of security door, make thief and playboy not reach lock core, thereby the thief can't operation technique be unblanked, and the playboy also can't block up in the lock core hole with toothpick, iron wire.
