Abstract
An earthquake automatic alarm mainly relates to a device which utilizes a spiral spring to magnify the vibration strength. The earthquake automatic alarm mainly adopts the function of magnifying the oscillation amplitude of a spiral spring (2) to ensure that a pendulum bob (3) and a copper sheet (4) are in contact with each other to generate a closed circuit current; and the combined action of the chip and the resistance promotes a loudspeaker (7) to send an alarm. The high sensibility and accurate and timely alarm are achieved through the adjustment of a scale regulator (5). The earthquake automatic alarm has the advantages of easy and convenient manufacture and low cost, and is suitable for using in various occasions and producing various craftworks.
Description
Technical field
The utility model relates to a kind of warning device, particularly a kind of earthquake autoalarm that utilizes volute spring to amplify oscillation intensity.
Background technology
In life at ordinary times, people relatively are short of the prevention and the escape knowledge of earthquake, are caught unprepared often when earthquake is attacked suddenly, flee for life in a hurry.Injures and deaths are not often directly caused by earthquake, be because people's flurried and buildings consequential injury causes on the contrary, so earthquake alarming device seem especially important naturally.But present earthquake alarming device can not be in time, the accurate forecast earthquake, and its cost costliness, and device is complicated, makes people forbidding.
The utility model content
It is inaccurate, timely that the purpose of this utility model is to solve existing earthquake alarming device, and the problem of cost costliness, discloses a kind of small and exquisite flexible, high practical earthquake autoalarm of accuracy.
The earthquake autoalarm is by one group of parallel circuit, the housing box, the volute spring holder, volute spring, pendulum, copper sheet, a kind of earthquake autoalarm that scale regulator and loudspeaker etc. are formed, it is characterized in that: the positive pole of circuit is connected with fixing volute spring 2, negative pole and copper sheet 4 adjacent (wherein two copper sheets are connected with lead), as two, when earthquake takes place more than three grades, volute spring 2 front and back, vacillate now to the left, now to the right and amplified Oscillation Amplitude, this moment, pendulum 3 was connected with copper sheet 4, entire circuit forms the closed-loop path, acting in conjunction through chip 6 and resistance R causes loudspeaker 7 to sound the alarm, thereby plays the warning function to people.Two copper sheets 4 of this device connect two copper sheets with lead respectively in pendulum front-left and dead astern, use the distance between scale regulator 5 adjusting copper sheets and the pendulum, thereby regulate the sensitivity of this device.The utility model is simple in structure, easy operating, carries, and is with low cost, is suitable for various occasions and uses, and be fit to make the handicraft and the toy of different shape.

Embodiment
By fixing spring seat 1 fixedly volute spring 2 and pendulum 3, when the vibration of earthquake more than two, three grades or same level, pendulum 3 just can be subjected to the effect all around of volute spring 2 to wave and contact with copper sheet 4, circuit forms the closed-loop path, and the acting in conjunction through resistance R and chip 6 makes loudspeaker sound the alarm at last again.
Pendulum 3 is fixed on the volute spring 2, is regulated making pendulum 3 and power supply copper sheet 4 very near by the scale regulator, but does not contact, so not conducting at ordinary times, loudspeaker can not sound the alarm yet.In case when having more than two, three grades earthquake take place, the pendulum all around is waved and copper sheet 4 is communicated with pendulum 3 make circuit turn-on, loudspeaker sounds the alarm.
Claims (2)
1, a kind of by parallel circuit, the housing box, volute spring, pendulum, copper sheet, a kind of earthquake autoalarm that scale regulator and fixing spring seat are formed, it is characterized in that: helical spring seat (1) is volute spring (2) and pendulum (3) fixedly, the positive pole of circuit is communicated with fixing volute spring (2), pendulum (3) is adjacent with copper sheet (4), two copper sheets connect with lead, when earthquake takes place, spring (2) has amplified Oscillation Amplitude automatically, pendulum (3) contacts with copper sheet (4), circuit forms the closed-loop path, and the acting in conjunction of process chip (6) and resistance (R) sounds the alarm loudspeaker (7).
2, a kind of earthquake autoalarm according to claim 1, it is characterized in that: lead connects two copper sheets (4), and by the distance between scale regulator (5) adjusting copper sheet (4) and the pendulum (3), changes its sensitivity.
