Abstract
The utility model relates to a coded theft proof alarm which is used for door locks. The utility model is characterized in that the theft proof alarm is composed of a machine shell (2), a control circuit board (3), an electric magnet (4), a digital password keyboard (5), a speaker (7), a lock body (8), a magnetic block (10), an offsetting spring (11) and a sound releasing hole (12). The upper end of the lock body (8) is provided with the magnetic block (10). The middle part of the block body is provided with a locking notch (6) with big caliber. The upper end and the lower end of the lock body (8) are respectively arranged in corresponding pistons. The offsetting spring (11) is arranged between the magnetic block (10) and the locking notch (6). The electric magnet (4) is close to the magnetic block (10). The control circuit board (3), the electronic magnet (4) and the speaker (7) are connected together by leads. The theft proof performance of the door lock is effectively improved by using the utility model.
Description
Technical field
The utility model relates to a kind of burglar alarm, is a kind of door lock combination type burglar alarm specifically.
Technical background
The burglar alarm that is used for family, why the user is reluctant to accept, it mainly is the too loaded down with trivial details and non insurance of gauge tap, switch commonly used is nothing more than combination type switch, concealed switch or contact witch etc., and their shortcoming is not that destructible is exactly a complex operation, and the utility model is installed simple and easy, reliable operation, good confidentiality need not existing mechanical type built-in lock is reequiped, and only needs to install additional outside former fore shaft to get final product.
Summary of the invention
The purpose of this utility model provides a kind of door lock combination type burglar alarm.
The technical solution of the utility model is: a kind of door lock combination type burglar alarm, it is characterized in that it is made up of casing (2), control circuit board (3), electromagnet (4), numerical ciphers keyboard (5), loudspeaker (7), lock body (8), magnetic patch (10), back-moving spring (11), sound releasing hole (12), described lock body (8) upper end is provided with magnetic patch (10), the middle part is provided with footpath at a gulp fore shaft (6), upper and lower side places respectively in the corresponding piston, between magnetic patch (10) and the fore shaft (6) back-moving spring (11) is set; Electromagnet (4) is near magnetic patch (10); Control circuit board (3), electromagnet (4), loudspeaker (7) connect by lead.
The beneficial effects of the utility model are: dial password unlocking, and picking lock is set distinguishes burglar alarm, improved the door lock theftproof performance.

The specific embodiment
At Fig. 1, Fig. 2, among first embodiment shown in Figure 3, a kind of door lock combination type burglar alarm, it is characterized in that it is by casing (2), control circuit board (3), electromagnet (4), numerical ciphers keyboard (5), loudspeaker (7), lock body (8), magnetic patch (10), back-moving spring (11) is formed, described lock body (8) upper end is provided with magnetic patch (10), the middle part is provided with footpath at a gulp fore shaft (6), when decoding successfully, the corresponding opening with casing of fore shaft is concentric, the corresponding opening dislocation of fore shaft during input password mistake with casing, the lock body upper and lower side places respectively in the corresponding piston, between magnetic patch (10) and the fore shaft (6) back-moving spring (11) is set, the user unblanks to finish, take out key, spring makes lock body reset automatically; Electromagnet (4) is near magnetic patch (10); Control circuit board (3), electromagnet (4), loudspeaker (7) connect by lead.
In second embodiment shown in Figure 4, a kind of door lock combination type burglar alarm, its circuit part is characterised in that it is made of telegraph key SB1～SB4, capacitor C1～C4, resistor R 1～R4, triode VT1, VT2, open type relay SSR, electromagnet L, vibrating sensor ND, speech chip IC, loudspeaker B, wherein telegraph key SB1～SB4 can set up the sky button for the coding button for strengthening secret effect in keyboard.When opening the door, the user imports preset password earlier, if input is correct at the appointed time, and then SSR controlled contact adhesive, the L conducting generates an electromagnetic field, and magnetic patch is inhaled, fore shaft aligns with lockhole, and the user can insert lockhole with key and unblank, if input the password mistake at the appointed time, SSR input no current then, off-state is held in controlled contact, magnetic patch attonity, fore shaft and lockhole dislocation, key can't insert lockhole and unblank, thereby reaches antitheft purpose.
In the present embodiment if deliberately bad lock body of sled of people is arranged, then will inevitably produce judder, after digital vibrating sensor ND detects judder, its output output triggering signal, voice firewood sheet IC is touched output voice telecommunication number, this signal amplifies rear drive loudspeaker B through VT2 and sends the audio alert sound that makes the thief worried, reaches the purpose of warning.
