The present invention relates to an impact detection device of a safe, and in particular, the piezo element detects the physical impact strength that the wall or door of the safe receives due to the impact applied from the outside of the safe and alerts only the impact strength corresponding to the predetermined impact level. By adjusting the dip switch to send out the contact signal step by step, it is configured so that the alarm contact signal does not occur except the strength of the shock level that needs to be checked in the security management of the safe. It relates to the shock detection device of a safe.

The security method of the safe is mounted in a general building, the security method of the safe is the disconnection method that sends out the alarm contact signal by disconnection operation of the contact switch when the door is opened for security, and the alarm contact signal by detecting the physical external shock applied to the wall of the safe. You can check the opening of the safe by using a vibration detection method that sends out.

Here, in the vibration detection method, the user sets the sensitivity control of the sensor in an analog manner according to the environment of noise, vibration, etc. in which range the alarm contact signal is transmitted according to the volume of vibration. . For example, in a place where the amount of vibration is large because the traffic of the vehicle is small, an alarm signal is generated at a greater vibration than this level.

However, the surrounding environment of the vibration detecting safe that detects an external shock and sends an alarm contact signal may change from time to time. That is, regardless of the unavoidable vibration of the roof, column, or wall around the safe, the vibration sensing face sensor can send out an alarm contact signal in response to minute changes.

Therefore, despite the fact that the vibration sensor face sensor does not generate an alarm signal for minute fluctuations in the vibration sensing safe box, it is easily malfunctioned when there is a physical external shock applied to the safe wall in the actual surrounding environment. Discontinuance such as a mistaken dispatch has occurred.

Therefore, the object of the present invention is to detect the physical impact strength of the walls or doors of the safe due to the impact from outside the safe, so that the piezoelectric element transmits an alarm contact signal only for the impact strength corresponding to the predetermined shock level. By adjusting the position step by step, it is configured not to send out alarm contact signal except the strength of impact level that needs to be checked in security management of the safe. To provide.
