Abstract

A hidden security device for a container of cargo transportation includes a case provided with an electronic processing unit; a tightly-seized device, including a plate, extending from the case, on which a displacement sensor communicating with the electronic processing unit is provided at a predetermined place; and a tightly-seized part, perpendicularly extending from the plate and having a flexing end; and an antenna, communicating with the electronic processing unit and extending out from the case to the flexing end of the tightly-seized part. The present security device can accurately record the time and frequency of opening the door plates of the container, and meanwhile it is disposed on the inner side of the door plates, and is readily concealed.

Claims

1. A hidden security device for container, comprising

a case, provided with an electronic processing unit;

a tightly-seized device, including

a plate, extending from said case, on which a displacement sensor communication with said electronic processing unit is mounted using pressure or friction fit at a predetermined place and

a tightly-seized part, perpendicularly extending from said plate and having a flexing end; and

an antenna, communicating with said electronic processing unit and extending out from said case to the flexing end of said tightly-seized part.

2. A security device according to claim 1, wherein said antenna is a thin elastic chip or is covered with an elastic chip.

3. A security device according to claim 2, wherein said tightly-seized device is of elastic material.

4. A security device according to claim 1, wherein said security device comprises a fixing device.

5. A security device according to claim 4, wherein said fixing device is a magnet provided in said case.

6. A security device according to claim 4, wherein said fixing device comprises a couple of wing plates extending from said plate and fixed by bolts or rivets.

7. A security device according to claim 1, wherein a vibration detector is placed in said case and communicates with said electronic processing unit for apperceiving vibrations at predetermined frequency.

8. A security device according to claim 1, wherein an anti-cheating blocker is placed on the outer side of said tightly-seized part for preventing the communication between said displacement sensor, antenna and said electronic processing unit from being cut down.

9. A container with a door structure of two door plates, comprising a hidden security device provided on the inner side of said door plates of container, including

a case, corresponding to a first door plate and having an electronic processing unit therein;

a tightly-seized device, comprising

a plate, extending from said case, on which a displacement sensor communication with said electronic processing unit is mounted using pressure or friction fit at a predetermined place corresponding to a second door plate; and

a tightly-seized part perpendicularly extending out from said plate through a distance between the two door plates and having a flexing end; and

an antenna, communicating with said electronic processing unit and extending out from said case to the flexing end of said tightly-seized part.

10. A container according to claim 9, wherein said tightly-seized part cooperates with a vertical doorpost of the first door plate to fix said security device, and said flexing end is disposed on the outer side of said door plates.

11. A container according to claim 10, wherein said antenna is a thin elastic chip or an antenna with an elastic chip.

12. A container according to claim 11, wherein said tightly-seized device is of elastic material.

13. A container according to claim 9, wherein said security device comprises a fixing device.

14. A container according to claim 13, wherein said fixing device is a magnet provided in said case.

15. A container according to claim 13, wherein said fixing device comprises a couple of wing plates extending from said plate and fixed to said door plate by bolts or rivets.

16. A container according to claim 9, wherein a vibration detector is placed in said case and communicates with said electronic processing unit for apperceiving vibrations at predetermined frequency.

17. A container according to claim 9, wherein an anti-cheating blocker is placed on the outer side of said tightly-seized part, corresponding to the distance between the first and second door plates, for preventing the communication between said displacement sensor, antenna and said electronic processing unit from being cut down.
