Abstract

The utility model relates to a warning device used for the five-safety lock. The utility model is characterized in that a casing is amplified, and an element 13 is reformed on the basis of original five-safety clock; a standing sleeve 9 is additionally designed on the original element; a sliding rod can slide in the standing sleeve through the standing sleeve, and the both sides of the sliding rod are respectively connected with a push rod and a top plate; a spring is arranged on the sliding rod. The purpose is that a warning device is added on the basis of the existing lock, and the defect the safety lock can not warn in the abnormal opening the door to enter the room is prevented, the utility model is characterized in that when the safety lock is abnormally disengaged the door, the push rod is extend out of the casing 1 under the action of the spring force, the top plate 8 is simultaneously driven to press a button 2, and a switched-on microswitch 3 can connect with the electronic warning device to warn. The utility model has the advantages that the structure is simple, only a little improvement is added on the basis of the original five-safety lock, and the cost is low.

Description

Warning device of safety lock

The utility model relates to a kind of mechanical alarm device that lock the five guarantees danger that is used for.The transformation part 13 that warning device is locked by the five guarantees danger, microswitch 3, spring 10 and the top board 8 that links together, slide bar 5 and push rod 11 amplify housing 1 and form.

At present, five safety locks of selling on the market, though pin behind the door, door is more firm with being connected of doorframe, promptly insert doorframe by an inclined-plane tongue pin and two cylinder ejector rod, seem comparatively robust, but in fact the thief forces open the door and often adopts destructive way when entering the room, and promptly with pin door is kicked out, because doorframe is made thiner at present, so employing said method, safety lock just do not have due having acted on.Based on above-mentioned situation, designed a kind of warning device of safety lock, be that a kind of of safety lock improved and replenish.

This apparatus features is, when lock during with the improper disengagement of doorframe, push rod stretches out shell 1 under the spring force effect, drive top board 8 simultaneously and press the button 2, and the microswitch 3 of connection can connect electronic alarm, reports to the police.This apparatus structure is simple, just does some improvement on the basis of original five safety locks and gets final product, and cost is low.

Below in conjunction with accompanying drawing this device implementation process is more clearly described.

Fig. 1 is a free state schematic diagram of the present utility model

Fig. 2 is a working state schematic representation of the present utility model

This warning device is seen Fig. 1, it is the space that utilizes housing 1 top of safety lock amplification, be fixed on the transformation part 13 on the axle 12, transforming part is to connect a upright cover 9 on the basis of original paper, be inserted with sliding bar 5 and the top board 8 and the push rod 11 that are attached thereto one at upright cover endoporus, microswitch 3 is installed above part 9, and this device free state is promptly opened when locking such as Fig. 1.

After door is closed pinning, warning device enters duty such as Fig. 2, at this moment, cylinder ejector rod 7 is pulled at key and is inserted doorframe 6 down, the upright cover of part 9 compresses spring 10 simultaneously, push rod 11 stretches out shell 1 and withstands doorframe 6, because the displacement of cylinder ejector rod 7 is greater than the displacement of top board 8, at this moment top board is apart from button 2(microswitch) also have a segment distance.

After the thief forced open the door, push rod 11 stretched out along shell 1 hole under the spring force effect, drove top board 8 press push button 2 simultaneously, connected microswitch 3, reported to the police by electronic alarm.

Claims

A kind of dangerous warning device of locking of five guarantees that is used for, this device is installed in the housing of five safety locks amplification, it is characterized in that design increases by a upright cover 9 on the basis of original paper 13, by upright cover one slide bar 5 is installed, slide bar 5 is connected with push rod with top board, along slide bar 5 a compression spring 10 is installed, is being fixed a microswitch on the shell wall above the upright cover.
