The door body 2 is provided with a handle 6 .

The side wall of the cabinet body 1 at the 4 places of the upper chamber or the 5 places of the lower chamber is provided with the magnetic suction type heavy hammer alarm device of the present utility model.

The magnetic suction type heavy hammer alarm device of the present utility model comprises a shell 7 for being installed on the cabinet body 1 of the safe, and a heavy hammer alarm mechanism is arranged inside the shell 7; the side wall of the shell 7 faces the cabinet body 1 A magnetic material layer 8 is provided, and the magnetic material layer 8 adopts materials with permanent magnetism such as permanent magnets; the side wall of the housing 7 facing the side wall of the cabinet body 1 is also recessed and provided with two horizontal installation grooves 9 arranged at intervals up and down, and the cabinet body 1 The side wall is provided with two horizontal clips 10 corresponding to the horizontal installation groove 9; the horizontal installation groove 9 and the horizontal clip 10 are compatible with each other; Closed on the side wall of the cabinet body 1;

The heavy hammer 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 horizontal 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 with a power supply 20 through a connecting wire 19, and a weight switch is connected in series on the connecting wire 19;

The weight switch includes an insulating cylinder 22 arranged vertically, the inner wall of the insulating cylinder 22 is connected with a conductive cylinder 24 through a connecting rod 23, and copper balls 26 (copper balls 26) are suspended from the top wall of the insulating cylinder 22 downwards through copper wires 25. 26 plays the role of a heavy hammer), the copper ball 26 is located at the center of the conductive cylinder 24 in a static state, and the angle at which the copper wire 25 swings when the copper ball 26 swings in any direction to a position in contact with the conductive cylinder 24 The position relative to the static state is less than or equal to 15 degrees and greater than 10 degrees, preferably 12-13 degrees, which can not only trigger the alarm sensitively when the safe is moved, but also avoid the copper ball 26 from swinging and causing errors due to unexpected factors such as most vibrations. Call the police. The conductive cylinder 24 is connected with a first wire 27, the copper wire 25 is connected with a second wire 28, and both the first wire 27 and the second wire 28 extend out of the insulating cylinder 22; The first wire 27 and the second wire 28 are connected in series on the connection wire 19;

The cabinet 1 at the top of the upper cavity 4 and the cabinet 1 at the bottom of the lower cavity 5 are respectively connected with a rectangular parallelepiped moisture-proof box; the moisture-proof box includes a box 29, and the box 29 is provided with a honeycomb-shaped moisture-proof block 30 . 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 field 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.

More than three connecting rods 23 are evenly arranged along the circumferential direction to ensure that the conductive cylinder 24 is firmly installed on the insulating cylinder 22 .

Among them, the insulating cylinder 22 is preferably a ceramic cylinder, and the material of the conductive cylinder 24 is preferably copper, aluminum or steel.

When using the safe that the utility model is installed, 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, after adopting the utility model, the articles in the cabinet can be prevented from being damaged by moisture. 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 the thief implements theft and moves the safe, it is difficult to keep the utility model in a horizontal state all the time. When the included angle between the utility model and the horizontal plane reaches 10-15 degrees, the copper ball 26 swings from the center of the conductive cylinder 24 to the side wall of the conductive cylinder 24, thereby connecting the power supply 20 of the electromagnet 15. Of course, when the thief carried the utility model, the violent vibration would also cause the copper ball 26 to deflect 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 of self-contained battery; Alarm 17 automatically reports to the police 30 seconds to 1 minute after being triggered, selects the alarm 17 of different models for use and can control the time of alarm delay.

In a word, after using the utility model, the safe can automatically send out an alarm when it is moved by thieves, deters the thieves and reminds the owner or security to protect the safe. Of course, the magnetic suction type heavy hammer alarm device of the present utility model can also be applied to other devices that require anti-theft.

The above embodiments are only used to illustrate and not limit the technical solutions of the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that the present utility model can still be modified or equivalently replaced. Any modification or partial replacement without departing from the spirit and scope of the present utility model shall fall within the scope of the claims of the present utility model.
