Abstract
The utility model discloses an earthquake alarm, which comprises a support plate, a support spring and a circuit board, wherein the support spring and the circuit board are arranged on the support plate; the upper end of the support spring is connected with a support container loaded with roll balls; a switch is arranged on the circuit board; a contact below the support spring is connected with the circuit board through a lead; foot margin springs are arranged on four corners below the support plate. The earthquake alarm provided by the utility model has the advantages of being low in manufacturing cost, simple to manufacture and particularly applicable for use in family, playing a certain pre-alarm role and minimally reducing the loss caused by earthquake.
Description
Technical field
The utility model relates to a kind of seismic monitoring and warning device, specifically is a kind of earthquake Alarm.
Background technology
Earthquake disaster takes place frequently now, and has not a particle of regularity, lets people in precipitate earthquake, pay heavy cost.
Summary of the invention
The utility model is exactly in order to solve the problems of the prior art, and a kind of earthquake Alarm is provided.
The utility model is realized by following technical scheme:
The earthquake Alarm of the utility model comprises back up pad and is arranged on support spring and the circuit board on the back up pad; The support spring upper end is connected the support vessels that is loaded with ball, and circuit board is provided with switch, and the contact of support spring below is connected with circuit board through lead; Four jiaos of the back up pad below are provided with the lower margin spring.
The superiority of the utility model is:
The earthquake Alarm of the utility model, cheap, make simply, be highly suitable in the family and use, can play certain forewarning function, the loss that earthquake is brought to people is reduced to minimum.
Description of drawings
Fig. 1 is the structural representation of the earthquake Alarm of the utility model;
Fig. 2 is the circuit theory diagrams of the utility model.
Among the figure: 1: back up pad 2: the lower margin spring
3: switch 4: circuit board
5: support spring 6: ball
7: contact 8: loudspeaker
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is carried out detailed explanation.
As shown in Figure 1, the earthquake Alarm of the utility model comprises back up pad 1 and the support spring 5 and circuit board 4 that are arranged on the back up pad 1.Support spring 5 upper ends are connected the support vessels that is loaded with ball 6, and circuit board 4 is provided with switch 3, and the contact of support spring 5 belows is connected with circuit board 4 through lead.Four jiaos of back up pad 1 below are provided with lower margin spring 2.
As shown in Figure 2, employed KD9300 family chip is a kind of extensive CMOS integrated circuit in the circuit, and the internal memory music is made up of oscillator, beat, tone color generator, ROM (read-only memory), address calculator and control, output etc.Its WV is 3V, triggers one time the internal memory circulation primary, and quiet WV is little, not power consumption.At first the energized switch 3, and when there were slight vibrations on ground, the ball 6 on the support spring 5 can tumble.Contact 7 is connected, and the trigger end TR of KD9300 obtains the positive pulse trigger pip from positive source, and KD9300 is triggered and works.The music signal of its output terminal output drives the loudspeaker sounding after amplifying through triode Q9014.
The earthquake Alarm of the utility model, cheap, make simply, be highly suitable in the family and use, can play certain forewarning function, the loss that earthquake is brought to people is reduced to minimum.
