Abstract
The utility model relates to a household earthquake alarm which can eliminate the interference of wind, mice and insects. In the utility model, a publicly known ring type contact of a weight hammer is entirely sealed in an insulating pipe which is long enough. The utility model can effectively prevent false alarms.
Description
The utility model relates to a kind of earthquake siren for household, wherein is used to start the flip flop equipment that alarm makes it to send alerting signal and is sealed in the insulation tube.
The earthquake region masses have the wise remark of an experienced person of " little shake is made a noise, and shakes greatly ", are perceiveed by the people but little shake is difficult, and especially Nobody Knows especially at night.Earthquake siren for household can give the police to little shake.Easy earthquake Alarm once had introduction on multiple publication, its structure all is made up of contact and signal generator.The contact is a suspending hammer garden ring type, and its structure is: hang a tup with sufficiently long thin wire, the weight freedom is sagging and pass a fixing becket, and hammer, ring insert signal generator with lead respectively, and its function is equivalent to a power switch.Hammer, ring do not contact under the normal condition, so the power supply open circuit, and alarm is not worked.When earthquake took place, annulus was with the point of fixity displacement, and weight keeps motionless because of static inertia, thereby hammered into shape, encircles and collide, and circuit is connected self-locking, alarm work.Because the gap of hammer, ring is very little, the weight messenger wire has sufficient length again, so as long as slight vibrations take place they are contacted with each other.But the very easily interference of wind-engaging, mouse, worm etc. and the misoperation of this exposed suspending hammer annulus contact may cause and misunderstand and unnecessary alarmed.
The purpose of this utility model provides a kind of more reliable earthquake siren for household, it has not only kept known simple alarm simple structure, highly sensitive characteristics, and suspending hammer circular ring type contact improved, make it to avoid the influence and the erosion of wind, mouse, worm, aqueous vapor etc., improve the credible reliability and the sensitivity of alarm.
The utility model is achieved in that suspending hammer circular ring type contact all is encapsulated in the sufficiently long not isometrical insulation tube together with messenger wire that the part of expanding of insulation tube is transparent.This insulation tube also can be isometrical, but the lower end has at least ten centimetres to be transparent.Weight and annulus are installed in transparent part.The insulation tube upper and lower opening seals with end cap, only stays aperture to pass lead.Owing to take such scheme, this contact just to get rid of the interference of wind, mouse, worm, reduced the erosion of aqueous vapor to the contact, guaranteed the reliability and the sensitivity of alarm.
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the alarm electrical schematic diagram.
Fig. 2 is the longitudinal profile structural map of first embodiment of the utility model.
Fig. 3 is the transparent part longitudinal profile structural map of second embodiment of the utility model.
Fig. 4 is A-A cut-open view of Fig. 3.
1 weight among the figure, 2 weight messenger wires, 3 metal rings, 4 annulus wiring, 5 upper end covers, 6 pass the aperture of messenger wire, 7 messenger wire fixed screws, 8.9 insulation tubes, (the 9th, transparent), 10 transparent tube inwall projectioies, 11 bottom end covers, the column on 12 bottom end covers, 13,14 fixed mounts.(combining as a whole) with end cap
The function of weight and annulus is equivalent to power switch in Fig. 1, and when earthquake took place, hammer, ring were collided, power connection and self-locking, and alarm work, its principle repeats no more.
In embodiment illustrated in fig. 2, encapsulation is waney with insulation tube, and it expands partially transparent and become step-like, the weight messenger wire passes the upper end cover aperture fix after place in circuit again, weight hangs down in the transparent tube.Metal ring is contained in the transparent tube, limits its position by the inwall step, and the diameter of transparent tube and length will match with weight, annulus, makes it carry out work according to functional requirement.When bottom end cover was packed transparent tube into, column just withstood metal ring and makes it fixing.Wiring on the annulus is drawn and place in circuit by sidewall.Insulation tube all has firm holder in two ends up and down, this device can be fixed on very easily wall or other firm place.Adjust the degree of tilt of insulation tube, make that weight is free contact with annulus when sagging and be positioned at annulus endoporus center, turn on the power switch, alarm just is ready at this moment.
In the embodiment shown in fig. 3, insulation tube is isometrical, and the lower end is transparent, and the transparent tube inwall has projection, in order to limit the position of metal ring.
Claims (3)
1, a kind of earthquake siren for household is made up of signal generator, weight circular ring type contact, it is characterized in that: weight circular ring type contact comprises that messenger wire all is encapsulated in the insulation tube, and the position that weight, annulus are installed is transparent; Insulation tube is by end cap seal up and down.
2, alarm according to claim 1 is characterized in that: insulation tube is waney, and it expands partially transparent and make step-like.
3, alarm according to claim 1 is characterized in that: insulation tube is isometrical, and its lower end is transparent, and the transparent tube inwall has projection.
