Detailed Description

The utility model will be described in further detail with reference to the drawings and the detailed description.

Example(s),

The embodiment discloses alarm equipment for preventing cultural relics from being lost, which is shown in fig. 1, and comprises a base 1, wherein the base 1 is positioned at the bottommost part of the whole alarm equipment and plays a role of structural support;

the anti-skid table further comprises an object placing platform 5, wherein the object placing platform 5 is used for placing exhibition cultural relics, and an anti-skid pad 6 with an anti-skid function is paved on the table top of the object placing platform 5.

For the object placing platform 5, it is slidingly installed above the base 1, as shown in fig. 2, first, guide posts 7 perpendicular to the object placing platform 5 are fixed at four vertex angle positions below the object placing platform 5; secondly, a guide hole 8 is formed in the base 1 corresponding to each guide post 7, the guide posts 7 are inserted into the guide holes 8 along the bottom ends and are connected with one end of a return spring 9, and the other end of the return spring 9 is fixed at the bottom of the guide holes 8. Therefore, the up-and-down movement of the object placing platform 5 can be realized through the cooperation of the guide post 7 and the guide hole 8; when the object placing platform 5 is loaded to move downwards, the reset spring 9 is compressed and deformed; when the load on the object placing platform 5 is taken away, the return spring 9 is required to restore to the original state, so that the object placing platform 5 can be sprung.

When the object placing platform 5 is close to or far from the base 1, the distance between the object placing platform and the base is changed; based on this, a work box 2 is provided on the table surface of the base 1, and the work box 2 is provided for the integrated circuit board 11 to be disposed in a space, and the integrated circuit board 11 is supported and disposed in the work box 2 by a bracket 13. Meanwhile, a magnetic attraction box 3 is arranged below the object placing platform 5, a magnet 10 is placed in the magnetic attraction box 3, a Hall induction switch which is matched with the magnet 10 to work is integrated on an integrated circuit board 11, meanwhile, a central processing unit is also integrated on the integrated circuit board 11, and the central processing unit receives signals transmitted by the Hall induction switch and is electrically connected with a buzzer alarm to control whether the buzzer alarm gives an alarm or not.

Therefore, when the cultural relics are placed on the storage platform 5, the reset spring 9 is compressed due to the increase of gravity, and the guide post 7 moves downwards along the guide hole 8, so that the magnetic attraction box 3 is contacted and attached with the working box 2; the magnet 10 adopts a permanent magnet for generating a constant magnetic field, the Hall sensor switch is in a normally open state, and at the moment, the magnet 10 and the Hall sensor switch which are very close to each other keep a working waiting state, and the CPU controls the buzzer alarm to not alarm. When the cultural relics are taken away, the guide post 7 moves upwards along the guide hole 8 under the reset action of the reset spring 9, the storage platform 5 is sprung away, the magnetic attraction box 3 is separated from the working box 2, the magnet 10 is separated from the Hall induction switch by a certain distance, the Hall induction switch is in a disconnected state, and the CPU receives a disconnection signal and then controls the buzzer alarm to give an alarm.

Further, in order to make the working box 2 and the magnetic attraction box 3 contact and adhere to each other, a good supporting effect can be achieved, the top end surface of the working box 2 is a horizontal surface, the bottom end surface of the magnetic attraction box 3 is also a horizontal surface, and meanwhile, the length and the width of the top end surface of the working box 2 are consistent with those of the bottom end surface of the magnetic attraction box 3.

Further, a buzzer alarm is provided at the back of the work box 2 so as to be not easily seen.

In addition, in order to realize power supply, a lithium battery 12 is disposed in the working box 2, and correspondingly, a charging and discharging module, such as an IP5306 charging and discharging module, is integrated on the integrated circuit board 11, and the lithium battery 12 supplies power to each component by using the charging and discharging module, and the power supply part is in the prior art and will not be described herein.

Therefore, the disclosed anti-relic loss alarm device of the embodiment has the anti-loss alarm function when the exhibition relics are placed, and can give an alarm in time once the exhibition relics on the object placing platform are taken away, so that security personnel can obtain alarm information in time, the protection of the exhibition relics is enhanced, and the anti-loss of the relics is better realized.
