The conductive liquid alarm mechanism includes a mounting plate 11 and a steel cross bar 12, the mounting plate 11 is provided with a vertical plate 13, and the middle part of the horizontal bar 12 is hinged on the top of the vertical plate 13; one end of the cross bar 12 is connected to the mounting plate 11 is connected with reset extension spring 14, and cross bar 12 is in horizontal position when reset extension spring 14 is in natural relaxation state; Press the plate 16, the iron core 21 of the electromagnet 15 is towards the cross bar 12; the mounting plate 11 below the press plate 16 is provided with an alarm 17, and the alarm button 18 of the alarm 17 is positioned at the press plate when the cross bar 12 is in a horizontal position 16, when the cross bar 12 is attracted by the electromagnet 15, the pressing plate 16 presses the alarm button 18 tightly;

The electromagnet 15 is connected to a power supply 20 through a connecting wire 19, and a conductive liquid switch is connected in series on the connecting wire 19;

The conductive liquid switch includes an insulating casing 22 arranged horizontally on the bottom surface. The insulating casing 22 is sealed and the cavity surrounded by the insulating casing 24 is filled with the conductive liquid 24 so that the conductive liquid 24 will not spill out.

The bottom of the insulating shell 22 is connected upward with a conductive rod 23, and the top of the conductive rod 23 protrudes from the conductive liquid 24 and is connected with a first wire 27; the inner wall of the insulating shell above the liquid level of the conductive liquid 24 is connected with a metal ring arranged horizontally 26, the metal ring 26 is connected with a second wire 28, the first wire 27 and the second wire 28 are sealed and stretched out of the insulating housing 22; the conductive liquid switch is connected in series through its first wire 27 and the second wire 28 On the wire; the insulating shell 22 is inclined to the angle that the bottom surface of the insulating shell 22 deviates from the horizontal plane when the conductive liquid 24 contacts the metal ring 26. The angle is less than or equal to 15 degrees and greater than 10 degrees; When the safe is moved, it can sensitively trigger an alarm due to tilting or large vibrations, and it can also avoid most unexpected factors such as vibrations from causing the liquid level of the conductive liquid 24 to oscillate and cause false alarms. The conductive rod 23 is respectively connected with a conductive metal plate 25 at the top of the liquid surface and the bottom of the liquid surface of the conductive liquid 24 . Thereby, the conductive performance between the conductive rod 23 and the conductive liquid 24 is enhanced, and the distance between the metal ring 26 and the conductive rod 23 is reduced by the conductive liquid 24 to reduce the resistance when an alarm is triggered.

The moisture-proof block 30 adopts common moisture-proof materials, such as lime, desiccant, activated carbon, etc.; the side of the box body 29 facing the middle partition 3 is evenly distributed with a number of moisture-absorbing holes 31 .

The moisture-proof box is connected to the cabinet body 1 through a pull-out connection structure, so it is very convenient for installation and replacement. The pull-out connection structure is a conventional structure in the art and will not be described in detail.

The return tension spring 14 (in a naturally stretched state) is arranged vertically and perpendicular to the mounting plate 11 . With this arrangement of the reset extension spring 14, the arm of force is long and the angle of application of force is better. Compared with the inclined springs, the tension direction of the tension spring 14 is closer to the direction perpendicular to the cross bar 12 after the cross bar 12 rotates under the tension of the return tension spring 14, so the maximum reset tension of the return tension spring 14 can be brought into play.

Wherein, the material of the insulating shell 22 is preferably made of ceramics, and the conductive liquid 24 may be various commercially available common conductive liquids, and may also be mercury or salt water.

During use, open safe door body 2, valuables such as cash are put into upper chamber 4 or lower chamber 5. The door of the safe generally does not need to be opened frequently. After the door body 2 is closed, the moisture in the cabinet body 1 is sucked into the moisture-proof box through the moisture absorption hole 31 and absorbed by the moisture-proof block 30 . The moisture-proof block 30 is made of materials such as lime or common desiccant, activated carbon, and its honeycomb structure can improve the hygroscopic performance. Therefore, the article in the cabinet can be prevented from being damaged by moisture after adopting the present invention. After using for a period of time, the moisture-proof box can be taken out from the cabinet body 1 to air to dry, so that the absorbed moisture can be volatilized; the moisture-proof box can be reused after airing.

When thieves steal and move the present invention, it is difficult to keep the present invention in a horizontal state. When the included angle between the present invention and the horizontal plane reaches or exceeds 10-15 degrees, the conductive liquid 24 contacts the metal ring 26, thereby turning on the power supply 20 of the electromagnet 15. Certainly, when thieves carry the present invention, violent vibrations will also cause the liquid level of the conductive liquid 24 to vibrate and trigger an alarm.

After the electromagnet 15 is energized, its iron core attracts the steel cross bar 12, so that the cross bar 12 overcomes the pulling force of the reset extension spring 14 to rotate, and the rotated cross bar 12 drives the pressing plate 16 to press the alarm button 18 tightly, triggering an alarm Device 17 buzzes the alarm, deters the thief and reminds the owner or the security guard to protect the safe. Alarm 17 preferably adopts the alarm 17 of self-contained battery; Alarm 17 automatically reports to the police 30 seconds to 1 minute after alarm 17 is triggered, selects the alarm 17 of different models for use and can control the time of alarm delay.

In a word, the present invention can automatically send out an alarm when it is moved by thieves, deter the thieves and remind the owner or security guard to protect the safe; in daily use, it can well absorb the moisture in the cabinet body 1 to prevent the stored items from being damaged by moisture.
