Description

Comprehensive anti-theft alarm door

The utility model belongs to door and window, the door manufacturing field of especially reporting to the police.

The metal plate type security door can play anti-theft effect in normal circumstances, but when adopting instrument such as drill rod to force open the door as the burglar, the metal sheet of the shop front produces flexural deformation with regard to being difficult to keep out, and the burglar can cause damage to people along in the distortion convolution place inlet chamber.In addition, except that the destruction to door leaf itself, the burglar also can adopt modes such as drilling anti-theft lock to destroy lock construction, to reach the purpose of committing theft.

The purpose of this utility model is a kind of anti-theft alarm door of design, makes it to have practical omnibearing alarming anti-theft function, no matter is that the burglar adopts the mode of destroying door leaf promptly, and the mode that still adopts the drilling lock core to destroy lock bolt is forced open the door and committed theft, and can both make rapid warning.And meet the common use habit of people, simple in structure, do not produce wrong report.

The purpose of this utility model is to realize by following design.

By door leaf, theftproof lock and trigger the comprehensive anti-theft alarm door that alarm etc. is formed, trigger alarm and contain circuits for triggering and two microswitch lead-in wires, wherein: the normal ON state microswitch K1 that is in series with the alarm power supply is located in the lock chamber of safe-guard door lock, when it is provided with the position and is positioned at the key back locking turn lock moving part the stroke that can directly or indirectly touch; The microswitch K2 that can present the on off operating mode variation with the switching of door leaf is connected across the trigger end of alarm trigger circuit trigger, and is mounted on the edge of door leaf; Trigger alarm and also contain a microseism sensitive switch K3, this K switch 3 is with microswitch K2 and is connected in parallel, and status switch is connected on the microseism sensitive switch K3 branch road.

After adopting design as above, have the state of alert of two kinds of grades to be available for users to select, a kind of is the pick-proof aposematism, and a kind of is more sensitive microseism aposematism.When selecting the pick-proof aposematism for use, the user disconnects selector switch K4, and K3 is inoperative for microseism this moment sensitive switch, and security door is only made warning to destroying forcing open the door of door leaf.Close when K4 closes, the warning of security door is mainly born by K3, this moment no matter the burglar use force open the door, the drilling lock core still is other any action of forcing open the door, security door all will be made warning.The theftproof performance of door is further strengthened.

Because whole warning device needs close owner and just works after the turn of Men Bingyong key is locked lock, other the time device be in fully and open circuit, do not misrepresent deliberately so device can not produce, and power consumption is low.

Description of drawings is as follows.

Fig. 1 is a profile elevation of the present utility model.

Fig. 2 is K1 installation drawing (off-state).

Fig. 3 is K1 installation drawing (a closed attitude).

Fig. 4 is the installation drawing of K2.

Fig. 5 is embodiment flip-flop circuit figure.

Fig. 6 is a microseism sensitive switch example structure partial sectional view.

Below in conjunction with accompanying drawing the utility model is described in further detail.

In Fig. 1, can find out, door leaf 5 is provided with has microswitch K1, K2, the triggering alarm 1 of microseism sensitive switch K3, can find out in conjunction with Fig. 2 and Fig. 3, normal ON state microswitch K1 is located in the chamber of safe-guard door lock 7, it is provided with the position and is positioned at the lock stroke that lock bolt sheet 2 can touch when locking turn, in conjunction with Fig. 4, Fig. 5 can find out, the microswitch K2 that can present the on off operating mode variation with the switching of door leaf is connected across the trigger end of alarm trigger, and microswitch K2 is arranged on the edge of door leaf, microswitch K2 is preferably the push button normally closed switch shown in the figure, button 3 with returning spring can be pressed along the direction of arrow, when the user selects to adopt the pick-proof state, status switch K4 is removed to off-state, at this moment, the branch road of microseism sensitive switch K3 disconnects, and microseism is reported to the police inoperative.The user closes door before leaving, and when door leaf cut out, button was depressed by doorframe 4, and K2 is opened circuit, and then, the user locks door with key derotation door lock, and in the turn process, the interior moving part compressing of lock K1 makes the power supply of triggering alarm and stands alert.Make door leaf produce distortion if the burglar prizes door leaf, produce the space between door leaf and doorframe, thereby push-button reset ejects, normally closed microswitch K2 also connects, and during K2 connected, the trigger conducting was reported to the police and kept alarm condition always, uses key operated door until owner.

Can find out also that in Fig. 5 a microseism sensitive switch K3 and microswitch K2 are and are connected in parallel, the status switch K4 that is arranged on alarm 1 panel is connected on the microseism sensitive switch K3 branch road.If status switch K4 disconnects, then the K3 branch road is inoperative, and Pickproof alarm is realized by K1, K2 assembly; When K4 was closed, the K3 branch road was independently born the vibrations of reporting to the police and is reported to the police.When vibrations produced, K3 was closed and cause sending chimes of doom, thereby except playing the pick-proof effect, can also make warning as drilling lock core, welding door-plate etc. to other destruction of burglar.

Microseism sensitive switch K3 is actually to a pair of and it can be installed in the chamber of alarm 1 at the contact of vibrating state to the generation closed action, and its structure is diversified, such as common ball-type, pendulum model contact etc.Fig. 6 is the microseism sensitive switch structure chart of a pendulum model contact, among the figure, the conduction yaw B that links to each other with circuit one end overhangs the center of a conductive ring H who links to each other with the circuit other end, if the external force vibrations are arranged, yaw B is when producing swing and enclose loop contacts, makes circuit turn-on.

The mode of moving part effect K1 is diversified in the lock, usefulness lock bolt slide plate 2 grades in last example directly act on, also can adopt with the mode of moving part indirectly-acting K1 in the lock and finish, such as using a flexible bowden cable, one end ties up on the moving plate of switch of K1, the other end ties up on the moving part in the lock (such as lock core rotation plectrum), and when locking turn, 3 lock core plectrums twine light line and make the K1 switch closure.

Triggering alarm of the present utility model can adopt conventional mode to make, general rest-set flip-flop all can obtain to use, Figure 5 shows that an embodiment of trigger, when the turn key back locking, the K1 closure, alarm is on the alert, force open the door as the burglar, the closed conducting of microswitch K2 or microseism sensitive switch K3, trigger triggers, and pronunciation chip (this example adopts LH-9561) sends chimes of doom at high level, after the circuit triggers, its state can not be controlled trigger in any case, so, even at this moment the burglar pulls out K2 or K3 can not stop the chimes of doom that alarm sends.

According to basic scheme of the present utility model, also can do the improvement of some integrities in force, such as can be in that be provided with on the door can be with the safeguard structure that lead covers or encapsulates that is connected that triggers between alarm and K1, K2, generally can adopt metal cap to be set or groove reaches this purpose.In addition,, can on button, be provided with one and have the Metallic rod of returning spring, directly contact with doorframe to avoid the K2 button for the button 3 direct collision doorframes of avoiding K2 damage.
