Now, the problem of be easy to causeing property loss.
To achieve the above object, the utility model provides the following technical solutions: it is a kind of from ring alarm nail, including on alarm
Shell, lock and pinning, the pinning are plugged on lock, and the intracavity bottom of the alarm upper casing is fixedly connected with by screw
Alarm lower casing, the pinning are plugged in alarm lower casing, and the inner cavity of the alarm upper casing is connected with circuit board, the electricity
Inductance, battery, buzzer, magnetic reed switch and microswitch are integrated on the plate of road, the microswitch is located at the center of circuit board
The inner cavity upside at place, the alarm upper casing is embedded with light-guiding pillar and spring, and the bottom end of the spring is supported on microswitch,
Microswitch trigger column is plugged on the downside of the microswitch, the bottom end of the microswitch trigger column is supported on lock,
The battery is electrically connected with inductance, buzzer, magnetic reed switch and microswitch respectively.
Preferably, the alarm upper casing, alarm lower casing are polyethylene insulation shell.
Preferably, the top of the alarm upper casing offers louver, and the position of the position of louver and buzzer
It is corresponding.
Compared with prior art, the utility model has the beneficial effects that the present invention can follow closely mating make with magnetic in the market
With deployment is quickly, easy to operate.Commodity can be played with double shielding, the hidden danger that commodity are lost is reduced, be able to achieve the antitheft mark of small side
Label think first time alarm when destroying inside market.To reduce a possibility that commodity are stolen.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of from ring alarm nail, including alarm upper casing
1, lock 2 and pinning 3, pinning 3 are plugged on lock 2, and the intracavity bottom of alarm upper casing 1 is fixedly connected with alarm by screw
Device lower casing 4, pinning 3 are plugged in alarm lower casing 4, and the inner cavity of alarm upper casing 1 is connected with circuit board 5, are integrated on circuit board 5
There are inductance 6, battery 7, buzzer 8, magnetic reed switch 9 and microswitch 10, microswitch 10 is located at the center of circuit board 5, report
It is embedded with light-guiding pillar 12 and spring 11 on the upside of the inner cavity of alert device upper casing 1, the bottom end of spring 11 is supported on microswitch 10, fine motion
The downside of switch 10 is plugged with microswitch trigger column 13, and the bottom end of microswitch trigger column 13 is supported on lock 2, battery 7
It is electrically connected respectively with inductance 6, buzzer 8, magnetic reed switch 9 and microswitch 10.
Wherein, alarm upper casing 1, alarm lower casing 4 are polyethylene insulation shell, and the top of alarm upper casing 1 opens up
There is louver, and the position of louver is corresponding with the position of buzzer 8.
Fig. 3 is that the circuit diagram of the utility model (uses based on the grand EM78P153BS SOP-8 chip of Taiwan justice in figure
