Description

A kind of earthquake Alarm

Technical field

The utility model relates to a kind of alarm, particularly relates to a kind of earthquake Alarm that is exclusively used in the earthquake situations that predict an earthquake, and is to having replenishing of earthquake Alarm kind now, belong to the surveying instrument category, layman's use that suitable earthquake takes place frequently and distinguishes.

Background technology

At present, existing earthquake Alarm is a lot, domestic earthquake prediction network builds up, but that employed earthquake Alarm all is complex structure, volume is very big, bring a high price, be unsuitable for extensively popularizing in town and country and promoting, and China to be an earthquake take place frequently more country in district, be in the peak period of earthquake outbreak in recent years again, carry out the outreach work of earthquake knowledge, make the people understand more shockproof escape knowledge, all press for the earthquake Alarm that a kind of simple type can be arranged and come out.

The utility model content

The purpose of this utility model is to overcome the prior art above shortcomings, improves by research, provides a kind of earthquake Alarm of popular style.This novel earthquake Alarm is simple in structure, cheap, workable, has certain sensitivity and accuracy, and is the energy with the dry cell, and safe and convenient, simple and practical can be widely used in the many places of people such as family and office.

The technical scheme that the utility model provides is: this earthquake Alarm, comprise platen and warning circuit thereof, be characterized in erectting on the described platen dividing plate that an angle bar shape is arranged, a sidewall of dividing plate is provided with electric bell, on another sidewall of dividing plate, be vertically installed with two metallic support rod, there is a plain conductor vertically downward in the bar head place system of the metallic support rod above it, the bar head place of the metallic support rod below it is provided with a metal ring, the plain conductor that top metallic support leverage passes from the metal ring of following metallic support club head, the lower end of this plain conductor is weighed down a plummet, on, following metallic support rod all is connected with warning circuit.

Compared with prior art, the beneficial effects of the utility model are: simple in structure, cheap, workable, have certain sensitivity and accuracy, and be the energy with the dry cell, safe and convenient, simple and practical can be widely used in the many places of people such as family and office.

Description of drawings

The structural representation of the embodiment that Fig. 1 provides for the utility model;

Fig. 2 is the warning circuit schematic diagram of the given embodiment of Fig. 1.

Number in the figure: 1. platen, the 2. dividing plate of angle bar shape, 3. electric bell, 4. Shang Mian metallic support rod, 5. plain conductor, 6. Xia Mian metallic support rod, 7. metal ring, 8. plummet, 9. power supply, 10. switch.

Embodiment

As shown in Figure 1, this earthquake Alarm that the utility model provides, comprise platen 1 and warning circuit thereof, wherein erect the dividing plate 2 that an angle bar shape is arranged on the platen 1, a sidewall of dividing plate 2 is provided with electric bell 3, on another sidewall of dividing plate 2, be vertically installed with two metallic support rod, there is a plain conductor 5 vertically downward in the bar head place system of the metallic support rod 4 above it, the bar head place of the metallic support rod 6 below it is provided with a metal ring 7, above metallic support rod 4 be plain conductor 5 from the metal ring 7 of following metallic support rod 6 bar heads, pass, the lower end of this plain conductor 5 is weighed down a plummet 8, on, following metallic support rod all is connected with warning circuit.

As shown in Figure 2, be simple warning circuit, wherein power supply 9 is dry cell of two joints of 1.5 volts, and upper and lower metallic support rod is connected in the circuit, earlier contactor 10 is closure state during use, under rest state, plummet 8 transfixions, the plain conductor 5 under by top metallic support rod 4 being passes the metal ring 7 at following metallic support rod 6 bar head places and does not brush up against metal ring 7, and at this moment circuit is off-state, circuit is obstructed, and electric bell 3 can not send alerting signal yet.And earthquake when taking place plummet 8 begin swing, and drive plain conductor 5 and rock, when plain conductor 5 touched metal ring 7, circuit was connected, electric bell 3 also begins to send alerting signal.

Claims

1. earthquake Alarm, comprise platen and warning circuit thereof, it is characterized in that erectting on the described platen dividing plate that an angle bar shape is arranged, a sidewall of dividing plate is provided with electric bell, on another sidewall of dividing plate, be vertically installed with two metallic support rod, there is a plain conductor vertically downward in the bar head place system of the metallic support rod above it, the bar head place of the metallic support rod below it is provided with a metal ring, the plain conductor that top metallic support leverage passes from the metal ring of following metallic support club head, the lower end of this plain conductor is weighed down a plummet, on, following metallic support rod all is connected with warning circuit.
