Horizontal celling lamp shaped earthquake alarm with elastic linking rod hammer

Abstract

The invention relates to a horizontal-type spring hammer-head ceiling-mounted lamp-shaped impending earthquake alarm which comprises the following three parts: a horizontal-type spring hammer-head, fixed contacts and a circuit; and which belongs to the field of impending earthquake alarm techniques that the swinging is enhanced by the physical amplification to trigger the circuit closing. The hammer head is arranged at the top end of the horizontal-type spring, so as to increase the swinging intensity and amplitude. Under the normal condition, the alarm functions like a ceiling-mounted lamp. In a stand-by state, the alarm loudspeaker circuit is disconnected. In an alarm state, the alarm loudspeaker circuit is closed to give the alarm, so as to warn the people to escape from the earthquake in advance. Particularly, when the earthquake occurs late at night, the alarm can not only wake up the people from sleep to escape but also automatically turn on the ceiling-mounted lamp to overcome the problem that the people don't find the lamp switch in a fluster. The horizontal-type spring hammer-head ceiling-mounted lamp-shaped impending earthquake alarm has simple structure and long service life, is applicable to the decoration in the bedroom, and is an ideal precaution device against the impending earthquake late at night.

Description

1. Technical Field [0001] The invention relates to a horizontal spring with hammer head ceiling lamp-shaped impending shock alarm, which is based on the slight shaking of the horizontal spring with a hammer head at one end of the horizontal spring as the alarm reference, and belongs to the impending shock alarm technology with closed shaking circuit. Especially when people do not directly feel the shaking of the ground surface, it can give an alarm in advance. 2. Background technology [0002] Until now, although the types of instruments used for imminent earthquake prediction and monitoring are many and advanced, people lack knowledge and skills about the causes of earthquakes and the selection of monitoring locations, making it difficult to make accurate predictions before the arrival of a major earthquake. It is predicted that the Tangshan and Wenchuan earthquakes are two examples of sorrow. Especially terrible is that the Tangshan earthquake that comes from late at night is e...

[0002] Up to now, although there are many types and advanced instruments for impending earthquake prediction and monitoring, people lack knowledge and skills on the causes of earthquakes and the selection of monitoring locations, making it difficult to make accurate predictions before a major earthquake comes. Forecast, the Tangshan and Wenchuan earthquakes are two sad examples, especially terrible, the Tangshan earthquake that came from the middle of the night is even more tragic
