Abstract
The utility model relates to a displacement antitheft alarm of simple structure, reasonable design and high sensitivity, which comprises a strong box and a battery. Rollers are arranged at the bottom of the strong box. The roller surface is in contact with one end of a pressure bar. The other end of the pressure bar is in contact with a pressure sensor. The signal output end of the pressure sensor is connected with the signal input end of a controller. The signal output end of the controller is connected with a voice alarm. The utility model has the advantages that the antitheft reliability of the strong box is higher because the pressure sensor is arranged, and the alarm is triggered to alarm as long as the pressure value on the strong box is changed.
Description
Technical field
The utility model relates to a kind of simple in structure, and is reasonable in design, and highly sensitive displacement burglar alarm belongs to alarm and makes the field.
Background technology
At present, the alarm of selling on the market on structure design, just can be reported to the police after strongbox is opened, and it is more blunt to react, and sensitivity is not high, does not have the effect of stealing of preventing.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design displacement burglar alarm a kind of simple in structure, reasonable in design, highly sensitive.
Design scheme: in order to realize above-mentioned purpose of design, 1, strongbox inside is provided with controller, power supply and spring, the spring bonnet is provided with pressure sensor, and the strongbox shell is provided with the design of phonetic alarm, is one of technical characterictic of the present utility model.The purpose of doing like this is: when the force value of pressure sensor changed, controller will trigger phonetic alarm and report to the police, and reached the purpose of prior warning.2, the depression bar of spring contacts with roller, and depression bar is fixed on the piston, and piston is connected on the stage clip, and the other end of stage clip is fixed on the design on the bonnet, is two of technical characterictic of the present utility model.The purpose of doing like this is: roller surface is rough, and when roller slided, depression bar moved up and down thereupon, stage clip compression or elongation, and the numerical value of pressure sensor changes.
Technical scheme: displacement burglar alarm, it comprises strongbox, battery, described strongbox bottom is provided with roller, idler wheel surface touches mutually with depression bar one end, the depression bar other end and pressure sensor touch mutually, and the signal output part that the signal output part of pressure sensor connects the signal input part of controller, controller connects phonetic alarm.
The utility model is compared with background technology, and the setting of pressure sensor makes the antitheft reliability of strongbox more reliable, as long as the force value that is positioned in the insurance takes place to become variation, will trigger alarm equipment alarm.
Description of drawings
Fig. 1 is the structural representation of displacement burglar alarm.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1.A kind of displacement burglar alarm, it comprises strongbox 1, battery 4, it is characterized in that: described strongbox 1 bottom is provided with roller 2,2 on roller touches mutually with depression bar 9 one ends, depression bar 9 other ends and pressure sensor 7 touch mutually, and the signal output part of pressure sensor 7 connects the signal input part of controller 3, the signal output part of controller 3 connects phonetic alarm 8.When the force value of pressure sensor 7 changed, controller 3 will trigger phonetic alarm 8 and report to the police, and reached the purpose of prior warning.
Described depression bar 9 is positioned at and is with spring 5 on fairlead and the depression bar 9 and spring 5 one ends touch mutually with the boss face on the depression bar 9.Roller 2 surfaces are rough, and when the thief produced strongbox to rock, it pressed bar 9 mutually with roller 2 and will slide with idler wheel surface, make and the numerical value that urges power sensor 7 changes, triggers alarm equipment alarm.
What need understand is: though the foregoing description is to the utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
Claims (2)
