Description
The utility model relates to the telltale of listening that a kind of electricity consumption transmits, particularly a kind of portable alarm that is used on the personal effects.
The application's item applicant had once applied for to Patent Office of the People's Republic of China that an application number was 92227274.3 and is called the utility model application case of " a kind of clamp type alarm " on July 8th, 92, it is by power supply 2, active news Chinese percussion instrument 1, compositions such as trigger switch 4 and alarm body 3, said trigger switch 4 is a kind of direct switches of clamp type of being made up of two clamping plate that have the recovery of elasticity effect between the two, with the insulation article the direct switch of clamp type is cut off during work, when alarm comes off, the insulation article leave clip, the warning that just pipes of switch closure, active news Chinese percussion instrument 1.Because during work, the direct switch of clamp type clamps the insulation article all the time, very easily cause clip recovery of elasticity function to reduce, when the insulation article leave the clamp type switch, may cause two clamping plate can't be closed and power alarm, perhaps when the clamp type switch is pulled away from the insulation article, because clamp type switch surface may stick a little article that insulate, can cause the clamp type switch insensitive like this, can not in time switch on to report to the police.
The purpose of this utility model is to overcome weak point of the prior art and provides a kind of switch highly sensitive, the portable alarm of reliable working performance.
The purpose of this utility model realizes by following approach.
A kind of portable alarm; by power supply; active news Chinese percussion instrument; compositions such as trigger switch and alarm body; power supply and active news Chinese percussion instrument are formed an electric loop by the closure of trigger switch; power supply; active news Chinese percussion instrument and trigger switch are installed on the alarm body; said trigger switch is made up of a kind of normal open switch and a kind of flip flop equipment that can impel the normal open switch closure etc.; said flip flop equipment is affixed by two blocks of last magnet that can be attached together and lower magnet and an a kind of end and lower magnet; the pull bar that the other end is connected with protected object is formed; last magnet is fixed on the alarm body; said normal open switch is placed on the position that can stop the lower magnet whereabouts; in the alarm chamber body; have between last magnet and the normal open switch on one section lower magnet; the space of following motion, said normal open switch are a kind of its closed switches that can impel when lower magnet drops to extreme position.
The purpose of this utility model can also reach by following measure.
Said normal open switch is a kind of reed relay.
At this moment, be to utilize lower magnet to drop to magnetic attraction that extreme position himself sends often to open tongue with two in the reed relay and be pulled together, thereby make its conducting and allow active news Chinese percussion instrument send acoustical signal to report to the police.
Said normal open switch is a kind of microswitch.
At this moment, then be to utilize lower magnet to drop to the extreme position compressing on microswitch, touch thereby lower magnet is conducted oneself with dignity and make the switch closure conducting.
Said lower magnet whereabouts extreme position can pick up lower magnet and makes outside the attractive force scope of its two absorption at last magnet.
Like this; when protected object tear pull bar, make lower magnet fall, when alarm enters alarm condition, the acting force of tearing pull bar as protected object disappears, if there is not artificial effect; lower magnet can not recover and last magnet absorption, and allows alarm be in alarm condition all the time.This function designs at similar following this situation: the soft metal chain of connection protected object and pull bar is torn the back and is broken.We know, the soft metal chain after breaking, and the acting force of then tearing pull bar disappears, but utilizes above-mentioned design, and alarm has entered alarm condition.
Said alarm body is connected with a kind of spring clamp hook that can be plugged on the carry-on clothing.
Said power supply is made up of the DC button cell, and said active news Chinese percussion instrument is made up of Microspeaker that is electrically connected and IC pronunciation integrated package.
In sum, the utility model has following advantage compared to existing technology: trigger switch is enclosed in the alarm chamber body, and extraneous unfavorable factor can't be disturbed it, and switch is highly sensitive, reliable working performance.Report to the police in time, sound construction, not fragile.

Accompanying drawing 4 is structure diagrams of the portable alarm of another kind described in the utility model.
Accompanying drawing 5 is circuit diagrams of the portable alarm of another kind described in the utility model.
Accompanying drawing 6 is a kind of portable alarm profile side views described in the utility model.
Below we carry out more detailed description to the utility model in conjunction with the accompanying drawings.
Embodiment 1:
With reference to accompanying drawing 3, power supply 2, active news Chinese percussion instrument 1, normal open switch 5 is electrically connected, and after normal open switch 5 was triggered device 6 triggering closures, power supply 2 active news Chinese percussion instruments 1 and normal open switch 5 can be formed an electric loop.
With reference to accompanying drawing 2, a kind of portable alarm, by power supply 2, trigger switch 4, active flood Chinese percussion instrument 1, compositions such as alarm body 3 and pull bar 7; Power supply 2 is made up of the four joint DC button cells that are compressed in two flat spring clamping plate central authorities, and said two flat spring clamping plate all are electrically connected with wiring board 8, and wiring board 8 is fixed in the alarm chamber body; Active flood Chinese percussion instrument 1 is made up of Microspeaker 9 that is electrically connected and IC pronunciation integrated package 10; Trigger switch 4 is made up of normal open switch 5 and flip flop equipment 6; here normal open switch 5 is a kind of reed relay; flip flop equipment 6 is by last magnet 11; lower magnet 12 and pull bar 7 are formed; last magnet 11 is placed on the platform that alarm body 3 inner chambers stretch out; lower magnet 12 can be unsettled and be attached together with last magnet 11; pull bar 7 one ends and lower magnet 11 are affixed; stretch out outside the alarm body 3 the other end; and can be connected with protected object by the soft chain of metal; reed relay is placed in lower magnet 12 bottoms; and can stop that lower magnet 12 falls; the cavity that between platform that last magnet 11 is sat and reed relay, has one section lower magnet 12 to move up and down; when extraneous protected object owing to lose etc. former thereby when tearing lower magnet 12; lower magnet 12 breaks away from the absorption of going up magnet 11 and falls; when dropping to extreme position; the magnetic attraction that lower magnet 12 is produced can be with the reed relay conducting; active news Chinese percussion instrument 1 begins to send acoustical signal and reports to the police; because lower magnet 12 whereabouts extreme positions can pick up lower magnet 12 and make outside the attractive force scope of its two absorption at last magnet 11; so, then need up top pull bar 7 if will remove acoustical signal.
