Abstract

The utility model relates to an alarm, which can cooperate with a locker to be used. The utility model adopts the mode that a lock rod is inserted into a hole of the alarm, a swinging rod controls a power supply switch, and a mechanical device controls a sound emitting device. The utility model can be used for preventing objects from theft, such as a vehicle, a door, etc. When the utility model is in use and a thief damages a lock to steal objects which are prevented from theft, the alarm is shaken and simultaneously gives an alarm, and therefore, the anti-theft alarming and threatening aim is achieved.

Description

The portable alarm that wears

The utility model relates to a kind of alarm that can match with multiple lockset and use.

The disclosed a kind of lock alarm of CN2199287Y has the function that cooperates burglar alarm in lock at present.But its only adapts to specific lock and is used, otherwise the dead bolt of lock can not cooperate with the lockhole of lock alarm, and pressing switch is inoperative, and the lock alarm loses anti-theft alarm function.

The purpose of this utility model is the advantage that absorbs existing alarm, overcomes its deficiency.Adapt to the little weakness of lockset scope at existing alarm, design a kind of portable alarm that wears, can cooperate with inserted link lock, ring lock, steel cable lock, cable chain, steel cable etc. easily, be used for the antitheft of objects such as car, door, and also have waterproof to drench, the stifled function of anti-sound.

Technical measures of the present utility model are on a shell (1), by mechanical hook-up control electronic sound-producing device.Specifically be to open through hole to wear hole (2) for what locking bar etc. wore on shell (1), shell (1) is gone up also has a turn-knob (3), and the swing arm (9) that turn-knob (3) can drive in the shell (1) swings, and sweeps away and wears hole (2).Swing arm (9) is under the pulling force effect of extension spring (11), can be stable lean against wears hole (2) and pressing microswitch (16) on one side, make microswitch (16) remain on closed condition, also can be stabilized in the another side that wears hole (2), leave microswitch (16).Battery (19) also is housed, electronic sound-producing device in the shell.Stir turn-knob (3) when using, swing arm (9) is put and is worn hole (2) another side, and microswitch (16) is opened, and battery (19) is switched on electronic sound-producing device, the break-off after a prompting of short ring of this alarm.At this moment locking bar was worn wear hole (2) connect this alarm together quilt cover be locked in car, door etc. by on the anti-theft object.Wait a moment the EOT end of timeout, this alarm begins warning.When causing that alarm rocks, send chimes of doom immediately.The swing arm (9) because locking bar is being stumbled, power switch can't be closed, and only unblanks just can close this alarm.

Because the utility model is to adopt swing arm (9) control power switch, the stumble technical measures of swing arm (9) of locking bar, so can suitably strengthen wearing hole (2), adaptation is used with multiple lockset, has overcome prior art and has only adapted to the shortcoming that cooperates with particular lock.This alarm is made portablely, one-object-many-purposes can be used for the antitheft of objects such as car, door easily again.

Figure one, be outside drawing of the present utility model.

Figure two, be structural drawing of the present utility model.

Figure three, be circuit block diagram of the present utility model.

Shown in figure one, shell of the present utility model (1) is to adopt the high material of physical strength to make, and it is to wear hole (2) that there is a through hole top.Wearing on the following shell (1) in hole (2) has a usefulness to refer to the turn-knob of stirring (3), and the bottom has many apertures to do the sound hole (5) of sound reproduction usefulness.Shell (1) is to be connected and composed with hinge axis (6) by protecgulum (7) and bonnet (8), can be fixing by bonnet screw (4) after closing.Wear shown in figure two on the following shell (1) in hole (2) axle (15) is housed, what axle (15) was adorned above is the turn-knob shown in the figure one (3).Overlapping the high swing arm of physical strength (9) one ends on the axle (15) in the shell (1).Turn-knob (3) can drive swing arm (9) and swing in swing arm groove (14), sweeps away to wear hole (2).Tension spring shaft (10) and tension spring shaft (17) are arranged on swing arm (9) and the protecgulum (7), extension spring (11) two ends are enclosed within tension spring shaft (10) respectively, on the tension spring shaft (17), swing arm (9) is under the pulling force effect of extension spring (11), can be stable lean against wears in the shell (1) on one side of hole (2), pressing microswitch (16), making microswitch (16) in off position.Swing arm (9) also can be stabilized in the another side that wears hole (2).Electronic sound-producing device box (12) and battery case (18) also are installed in the shell (1), wherein in the electronic sound-producing device box (12) electronic sound-producing device are housed, battery case is equipped with battery in (18).

Describe the course of work of the present utility model in detail below in conjunction with figure three.

Triggering delay circuit (22) shown in figure three, start cue circuit (20), start delay circuit (23), phonation circuit (24), piezoelectric ceramic piece (25) and movable sensor (21) are included by electronic sound-producing device.When using the utility model, hold shell (1) bottom, dial turn-knob (3) with finger, turn-knob (3) upset drives swing arm (9) upset simultaneously and stops to the another side that wears hole (2), and the microswitch (16) of being pressed is decontroled, and microswitch (16) is converted to opening by cutting out, battery (19) and electronic sound-producing device have been connected, the audible signal of the instantaneous output of start prompting (20) circuit makes phonation circuit (24) promote the short ring of piezoelectric ceramic piece (25) simultaneously, and prompting is started shooting.Because alerting signal that (23) circuit temporary interruption has been delayed time in start, this alarm suspends warning, at this moment alarm is overlapped together to be locked in by on the antitheft thing.Wait a moment start time-delay (23) circuit and change the signal conduction state over to, this alarm begins warning.When the people steals by antitheft thing, cause that alarm rocks, movable sensor (21) output signal, through triggering time-delay (22) circuit, start delay circuit (23) makes phonation circuit (24) work, and promotion piezoelectric ceramic piece (25) sends chimes of doom, the threatening robber.This moment, the robber desired to close this alarm, can not reset owing to wear locking bar in the hole (2) swing arm (9) of stumbling, and pressing switch (16) remains on opening, and this alarm is still reported to the police.Wherein trigger time-delay (22) circuit, can make that alarm is every to be touched, send a period of time tweeting sound, only open lock, just can close alarm.

In order to improve the reliability of this alarm, wherein electronic sound-producing device is to be encapsulated in the electronic sound-producing device box (12), and only piezoelectric ceramic piece (25) communicates in the external world through piezoelectric ceramic piece vocal hole (13).So improved the anti-performance that can not report to the police of being drenched by water.The box face portion that also has the piezoelectric ceramic piece vocal hole (13) of electronic sound-producing device box (12), leave the distance that supplies sound reproduction usefulness with protecgulum (7), chimes of doom not only can also improve the performance that anti-chimes of doom is blocked by swing arm groove (14) sound reproduction by sound hole (5) sound reproduction.

Claims

A kind of portable alarm that wears that cooperates with lock, wearing hole (2) on the shell (1) wears for locking bar, also has mechanical hook-up control electronic sound-producing device, it is characterized in that sweeping away the swing arm (9) that wears hole (2), in swing arm groove (14), swing, controlling the duty of microswitch (16).
