Abstract
The utility model discloses a wireless earthquake and anti-theft alarm doubling as a doorbell, which relates to the technical field of alarm instruments. The alarm is characterized in that: a quake-sensitive sensor, which comprises a transparent plastic shell, a piston, a sensitivity-regulating screw, mercury, metal electrodes and the like, is connected with a wireless transmitter through wires, and wirelessly communicates with a wireless receiving acoustic device, and a sound-controlled red lamp is mounted nearby. The mercury in the quake-sensitive sensor can roll due to earthquake or the vibration made by an intruding thief to touch the two metal electrodes, the wireless transmitter is switched on through the wires to transmit radio waves, the wireless receiving acoustic device receives the radio waves and then emits warning sound, the nearby sound-controlled red lamp is lit up at the same time, and thereby the alarm simultaneously gives the sound and light alarm. The sensitivity of alarm can be regulated by adjusting the sensitivity-regulating screw of the quake-sensitive sensor according to requirements. The alarm has the advantages of reliable performance, simple structure, cheapness, regulable sensitivity and the like, is convenient to operate and easy to popularize, and is particularly suitable for use by families and grass-roots units.
Description
Technical field:
The utility model relates to the electronic warning instrument, definite a kind of earthquake of saying so, antitheft double doorbell wireless alarm.
Background technology:
China is one of earthquake prone areas, has earthquake to take place in the time of in recent years, and earthquake brings tremendous loss can for people's lives and properties and economic construction.Little shake is the omen of big shake often, if can timely escape will avoid unnecessary injures and deaths when little shake.Therefore many research and patent reports about earthquake Alarm are arranged in recent years, and the relevant report of various burglar alarms is more.But most complex structures, the manufacturing cost height costs an arm and a leg, so be difficult to popularize at average family and grass-roots unit.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, low cost of manufacture, low price, universal easily a kind of earthquake, antitheft double Doorbell alarm device, the shake dependent sensor of earthquake Alarm is placed the wall top, and when body of wall was subjected to sharp pounding, the shake dependent sensor was passed to wireless launcher with electric signal, the wireless receiving acoustics is sent alarm sound after receiving, the reminds people escape.Be placed on the antitheft place of need such as door, window, drawer, cabinet, fence, warehouse and be subjected to also can reporting to the police as burglar alarm when the robber such as prizes, pounds, takes off at improper use vibration if will shake dependent sensor, can be used as wireless doorbell at ordinary times and use.
This achievement has solved earthquake, burglar alarm complex structure, make difficulty, price is expensive, and the difficult problem of popularizing is a kind of dependable performance, sensitivity is adjustable, earthquake, antitheft double Doorbell alarm device simple in structure, cheap, easy to operate, that popularize easily.
It comprises transparent plastic shell, mercury, the shake dependent sensor that metal electrode etc. are formed, wireless launcher, the wireless receiving acoustics, it is characterized in that: mercury (3) is equipped with in the bottom of transparent plastic shell (2) arc of shake dependent sensor (1), enclosure is provided with piston (4), its underpart is provided with metal electrode (5) and metal electrode (6), be connected with wireless launcher (9) with lead (8) by lead (7) respectively, and with wireless receiving acoustics (10) radio communication, acoustic control red light (11) is housed near it, the top of piston (4) is connected with sensitivity adjusting spiral (12), its top is provided with suspension ring (13), and the foot of transparent plastic shell (2) is provided with fixedly inserted link (14) of mercury storehouse double as.
The utility model has the advantages that simple in structure, sensitivity is adjustable, dependable performance, manufacturing with low cost, easy, not power consumption when not reporting to the police, adopt radio communication, need not wiring, both can make earthquake Alarm, can make burglar alarm again, can make doorbell at ordinary times and use, be particularly suitable for average family and grass-roots unit and use.
Below in conjunction with drawings and Examples the utility model is further described.
Description of drawings
Accompanying drawing is a structural representation of the present utility model
Embodiment
The plastic casing of shake dependent sensor adopts transparent plastic to make, and wireless generating means and wireless receiving acoustics adopt wireless doorbell to make.Get all the ready shown in the accompanying drawing behind the parts, with reference to using behind the accompanying drawing assembling and setting.As be applied to earthquake alarm, the lower end inserted link of shake dependent sensor can be inserted sucker and be adsorbed on smooth wall top, or adopt the suspension ring of shake dependent sensor to be fixed on the wall.During earthquake, body of wall rocks, mercury in the shake dependent sensor is owing to rocking of body of wall rolled, two metal electrodes are connected, signal passes to wireless launcher by lead, makes power connection and emitting radio wave, and the wireless receiving acoustics is sent alarm sound after accepting, the acoustic control red light lights, thereby realization sound, light are reported to the police simultaneously.As be applied to antitheft, can with the shake dependent sensor with sucker, suspension ring or the adhesion of other method, be fixed on door, window, cabinet, drawer, warehouse and fence etc. and locate, the physical vibration that prize when the robber invades, pound, take off and push-and-pull etc. moved, the mercury of shake in the dependent sensor is rolled, electrode connect and send sound, light is reported to the police.The user can regulate sensitivity as required, and the sensitivity adjusting spiral that shakes dependent sensor is turned clockwise, and piston is advanced downwards, and metal electrode is nearer apart from mercury, and slight vibration can be reported to the police.Otherwise piston furthers upward during the inhour rotation, and metal electrode becomes far away apart from mercury, must could report to the police than strong vibration.The utility model is the multifunction alarm device that a kind of dependable performance, average family easy to use, very suitable and grass-roots unit use.
