Description

Multifunctional theft-proof alarm lock

The utility model relates to a kind of coded lock with alarm.

Anti-coded lock, the alarm of usurping has been widely used in vehicle, door and window, cabinet etc.

The CN2116741U patent application discloses a kind of encryption cylinder lock of reporting to the police, key is a cross, can increase the pellet shot from a slingshot number of lock and duplicate difficulty, key can insert from four different directions, just can unblank but have only when a correct direction is inserted, otherwise give the alarm, when unblanking by force or destroying the installation position, also can report to the police.This is the same with existing other theftproof lock, all need change old lock, and key is stolen, loses or stolen timing, all may be unlocked, and its reliability is not high.

Existing door and window, cabinet burglar alarm generally become power amplifier, loudspeaker and power supply etc. to form by sensor, time-delay triggering controller, language set.Especially the protecting against shock sensor has been widely used in burglar alarm.

The purpose of this utility model aims to provide a kind of machinery and combines with electronics, and is multiple functional, and highly versatile can be installed in the multi-functional reinforced anti-theft alarm lock on the antitheft cabinet of door, safety cabinet and need reinforcement.

Basic scheme of the present utility model is that (vane type lock) puts a plane machinery feel formula coded lock above original tapered end or keyhole, its number interchangeable, the original key hole is covered full when closing, be provided with tamper-proof trigger switch in the coded lock and be connected with alarm, can be provided with the external magnetic switch socket of magnetic switch and multichannel in the alarm with the back disconnection of unblanking " long make and break is closed ".

The utility model comprises mechanical code lock, microswitch and triggering language alarm.The shell of mechanical code lock is provided with lock core hole, is provided with lock core cover in the lock core hole, and other establishes the lock core cover push button, establishes lock core cover push button hole on the shell.Microswitch is positioned at the lock core cover side.Triggering language alarm becomes power amplifier, loudspeaker and power supply etc. to form by protecting against shock sensor, magnetic switch, time-delay triggering controller, language set, the protecting against shock sensor is positioned at coded lock, normally closed magnetic switch triggers controller with time-delay and is connected, the output of time-delay triggering controller connects language set and becomes power amplifier, and language set becomes the output of power amplifier to connect loudspeaker.Microswitch is connected with the triggering language alarm.

The digit wheel of mechanical code lock can be established 3, and digit wheel is provided with number tone mark screw.

Magnetic switch polyphone in the lock in microswitch and the alarm.So that when not opening this lock, if open door with other method, then the last alarm of door is reported to the police immediately.

Time-delay triggers controller can establish external magnetic switch socket, external magnetic switch can be contained on window, balcony, cabinet or the valuables, like this, earlier do not climb into indoor or when opening the cabinet or moving valuables, promptly can report to the police automatically when opening this lock from window, balcony.

The utility model highly versatile is suitable for being installed in door, and safety cabinet maybe need be strengthened on the cabinet of burglar alarm; It is installed easily, need not change or change former lock; Strong security, but own coding, digit wheel can be established false shelves, are difficult for opening steathily, and feel is difficult for during day time operation being found out coding by other people that night, use need not thrown light on to sign indicating number; Security reliability is good, false alarm can not occur, in case key is stolen or the quilt imitated, all can't open, and also can prevent to fill in foreign matter from keyhole, because of password adopts frame for movement, so be not afraid of power down.

Fig. 1 is an outside drawing of the present utility model.

Fig. 2 removes elevation behind the shell for the utility model.

Fig. 3 removes vertical view behind the shell for the utility model.

Fig. 4 is the vertical view of digit wheel.

Fig. 5 is the elevation of digit wheel.

Fig. 6 is the schematic diagram of magnetic switch and alarm.

To shown in Figure 6, the utility model is by plane machinery feel formula coded lock, microswitch (11), protecting against shock sensor (12), normally closed magnetic switch (K as Fig. 1 ₁, S ₁, M ₁), time-delay triggers controller (26) and becomes power amplifier (27), loudspeaker compositions such as (28) with language set.Coded lock comprises 3 digit wheels (8), 3 knobs (1), push button (3), lock core cover (17), securing member (2,19), shell (6), bottom (22) etc., the digit wheel number of being provided with wheel shallow bore hole (9) and number wheel deep hole (10), and number wheel stage clip (23), number wheel shelves (24), the digit wheel center number of establishing wheel rotary knob rod (25), number return-to-zero shelves (21) are located between digit wheel and the bottom.Shell is provided with lock core hole (7) and push button hole (4) so that be placed on the lock core (5) of former lock (18).Lock core cover is provided with cover plate spacing hole (15) and cover plate push button fixing hole (16), and connects cover plate limit spring (14).Can establish number tone mark screw (20) in the digit wheel side.In other portal (13) that go between of leaving of protecting against shock sensor (12).

Referring to Fig. 6, protecting against shock sensor (12), normally closed magnetic switch (K ₁, S ₁) be connected S with time-delay triggering controller (26) ₁Be tongue tube, M ₁Be magnet.The output that time-delay triggers controller becomes power amplifier (27) through language set, connects loudspeaker.

Microswitch in the lock and the polyphone of the tongue tube in the alarm, so when not opening this lock, if open door with other method, then the alarm on the door breaks away from the magnet on the doorframe, reed switch conduction triggers immediately and reports to the police.

Time-delay triggers controller also can external magnetic switch S ₂, M ₂And S ₃, M ₃Time-delay triggering controller becomes power amplifier with language set be general circuit, repeats no more here.

The wheel transposing of number shelves number is to lock a screw with shelves to change the hole and realize.

Earlier with digit wheel knob (1) return-to-zero, check the number according to the number of finishing in advance then and can open the lock core cover of coded lock during use, expose the keyhole of former lock core, at this moment key can insert former lock and opens the door.Owing to unblank the normally closed magnetic switch S that is connected with alarm in the lock after aiming at number ₁Disconnect, therefore can not report to the police.If to the wrong number sign indicating number, obviously can't expose the keyhole of former lock core; If adopt destructive (for example pound, bump, sled hits etc.) to open, the protecting against shock sensor starts alarm with output signal; If with methods such as picking lock tongues, so long as not aiming in number goes into, long make and break is closed K and is not disconnected magnetic switch S when opening the door in the lock ₁Leave magnet M ₁, trigger alarm automatically and report to the police immediately.
