Concealed anti-tamper device

Abstract

A concealed anti-tamper device to prevent unauthorized opening and tampering with a manufactured product includes a shell, an anti-dismantling structure concealed in the shell, and at least one key. The shell defines a through hole and a slot. The anti-dismantling structure includes anti-dismantling hook module with hook, driving module, and resetting component anti-dismantling hook module. The anti-dismantling hook module is movable within the shell, and when the product is to be locked, the separate key rotates the driving module, which drives the hook of the anti-dismantling hook module to embed in the slot. The key is rotated in the opposite direction to unlock, until the driving module separates from the anti-dismantling hook module, and the resetting component separates the hook from the slot by the restoring force of a spring.
