Description
Technical field
The utility model relates to physics magnetic fields, is specially a kind of magnetic levitation alarm.
Background technology
The living standard of present people generally improves, income and personal property increase gradually, comprise enterprise and national public activity field, as family, bank and museum etc., especially the development of society in recent years causes rural area empty nestor in the majority, and the basic disability of these old men, some lawless persons have just kept a close watch on such family, therefore there is a lot of tragedy, people start to think a lot of way, such as country provides some to help from the perspective of policy, but the universal face of doing like this is still large not, therefore some people just starts safety supervision control, peace alarm, but these things for rural area these empty nestors seem very complicated and also can not use, safeguard very inconvenient, so research invention is a kind of simple, the low alarm easy to use of cost just seems and is necessary very much, also there is a lot of alarms now, a kind of magnetic suspension earthquake alarm as described in Chinese patent 201010211738.4, although volume is little, also can use under grid power blackout situation, but winding coil and driver element make and structure aspect is still more loaded down with trivial details, be placed in some specific environments in rural area and just cannot use.
Summary of the invention
In order to solve the problem, the utility model provides the magnetic levitation alarm that a kind of production and application convenience, cost are low, be convenient to installation.
For achieving the above object, a kind of magnetic levitation alarm of the utility model, comprise magnetic patch 2, casing 3, lower magnetic patch 5, suspension bar 7, both positive and negative polarity contact 8, suspension magnetic patch 10, alarm 11, it is characterized in that plank 9 is placed in the unlimited casing 3 in bottom surface, casing 3 top is by gemel connection case lid 11, plank 9 upper middle position place is provided with lower magnetic patch 5, nonmagnetic metal support 1 is had with lower magnetic patch 5 central point coaxial cable Triangle-Profile, support 1 top is provided with the bracing ring 4 identical with lower magnetic patch 5 size, bracing ring 4 top is placed with magnetic patch 2, lower magnetic patch 5 upper middle position is placed with the non magnetic suspension bar 7 of cone-shaped, suspension bar 7 low side is provided with the bar point 6 of carrying magnetic metal, suspension bar 7 upper end connects the suspension magnetic patch 10 that upper surface is electric conductor, lower magnetic patch 5 periphery is provided with both positive and negative polarity contact 8, both positive and negative polarity contact 8 connects the alarm 12 being arranged on casing 3 lateral surface built-in signal emitter by wire.
Further, the peripheric surface of casing 3 adopts clear glass.
Further, both positive and negative polarity contact 8 is fan-shaped concavo-convex, and is alternately connected to positive and negative polar curve below both positive and negative polarity contact 8.
Further, being N pole above upper magnetic patch 2, is N pole above suspension magnetic patch 10, is S pole above lower magnetic patch 5.
The beneficial effects of the utility model are: easy to use, cost is low, be convenient to install.
Accompanying drawing explanation
Fig. 1 is the utility model box house perspective view;
Fig. 2 is the outside main TV structure schematic diagram of the utility model.
In figure: support 1, upper magnetic patch 2, casing 3, bracket loop 4, lower magnetic patch 5, bar point 6, suspension bar 7, both positive and negative polarity contact 8, plank 9, suspension magnetic patch 10, case lid 11, alarm 12.
Embodiment
Example 1
As Fig. 1, shown in 2, a kind of magnetic levitation alarm, comprises support 1, upper magnetic patch 2, casing 3, bracket loop 4, lower magnetic patch 5, bar point 6, suspension bar 7, both positive and negative polarity contact 8, plank 9, suspension magnetic patch 10, case lid 11, alarm 12, described plank 9 is placed in the unlimited casing 3 in bottom surface, the peripheric surface of casing 3 adopts clear glass, casing 3 top is by gemel connection case lid 11, plank 9 upper middle position place is provided with lower magnetic patch 5, nonmagnetic metal support 1 is had with lower magnetic patch 5 central point coaxial cable Triangle-Profile, support 1 top is provided with the bracing ring 4 identical with lower magnetic patch size, bracing ring 4 top is placed with magnetic patch 2, lower magnetic patch 5 upper middle position is placed with the non magnetic suspension bar 7 of cone-shaped, suspension bar 7 low side is provided with the bar point 6 of carrying magnetic metal, suspension bar 7 upper end connects the suspension magnetic patch 10 that upper surface is electric conductor, be N pole above upper magnetic patch 2, be N pole above suspension magnetic patch 10, be S pole above lower magnetic patch 5, lower magnetic patch 5 periphery is provided with both positive and negative polarity contact 8, both positive and negative polarity contact 8 connects the alarm 12 being arranged on casing 3 lateral surface built-in signal emitter by wire, both positive and negative polarity contact 8 is fan-shaped concavo-convex, and be alternately connected to positive and negative polar curve below both positive and negative polarity contact 8.
