An anti-tampering and embezzling seal based on the Internet of Things

Abstract

The invention discloses an anti-tampering and embezzlement seal based on the Internet of Things, which includes an impact part, a substrate connected to a transfer body is arranged at the lower part of the lower casing, a lower enclosure is arranged at the rear of the substrate, and a lower enclosure is arranged on the upper casing. The stacked upper enclosure, the upper enclosure and the lower enclosure are overlapped and closed to form a protective cavity for circuit components; the substrate is provided with at least one impact hole pointing to the transfer body, and the impact part is provided with a corresponding through hole that can The impact head that passes through the impact hole downwards is provided with an elastic body that presses downwards corresponding to the impact head, the impact head is connected with a locking part that restricts its fall, and the upper shell is provided with an unlocking part connected with the locking part; It can reduce the chance of maliciously stealing the seal when opening the box, and improve the controllability.

Description

technical field [0001] The invention relates to a seal under the intelligent control of the Internet of Things, in particular to an anti-tampering and embezzlement seal based on the Internet of Things. Background technique [0002] In office units such as enterprises, institutions, governments, etc., in order to make the use of official seals and other seals efficient and controllable, with the support of the development of network intelligence technology, the combination of control, sampling, counting, storage and other means on the seals can be realized, such as on the seals Setting up locking mechanism, authentication mechanism, video camera recording mechanism, wireless communication mechanism, etc., all of which must be realized by setting circuit components in the seal, so that the use process can be controlled and use records can be made, but there are still malicious uses without The risks that are recorded and monitored, such as dismantling the housing to expose the...

Problems solved by technology

The closest prior art patent document (publication number US5271322A) discloses a disposable postage stamp marker provided with a frame 20 having an open bottom 42, a stamp 70 attached at the lower part 66 of a movable housing 64, the stamp 70 being located at the open bottom Below 42, there is a notch assembly 86. After the counting reaches the preset usage quantity, the notch assembly 86 drives the telescopic arm 84 through the solenoid 82 to release the locking lever. The bottom moves to destroy its integrity, making it unusable and discarded; the stamp 70 protrudes out of the bottom 42, and the contact arm 72 contacts the member 74 to count with the movement of the shell 64 during stamping. Since the bottom 42 is open and relatively movable with the parts, No need to disassemble, the relative position between the seal 70 and the frame 20, the seal 70 and the notch assembly 86 can be stopped by means of a card, a plug or a clip, and it is possible to cheat without counting stamping or making the notch assembly 86 inoperable , which weakens the control of its process and quantity. In addition, its control is limited by the battery power supply. No power or removing the battery will cause abnormal counting.
