Abstract

An anti-tamper device includes a top component, a reciprocating component, a bottom component, a rotatable rod, a movable sleeve, and a circuit element. The top component has a first guide portion and a second guide portion. The reciprocating component can reciprocate between a first position and a second position. The bottom component has a fixing rod corresponding to the second guide portion. The rotatable rod is pivotally connected to the fixing rod. When the movable sleeve partially sheathes both on the rotatable rod and the fixing rod, and the top component correspondingly is engaged with the bottom component, the rotatable rod is movably engaged with the second guide portion to drive the reciprocating component moving to the first position, so as to trigger the circuit element generating an electronic signal, and to drive the second guide portion pushing the movable sleeve to completely sheath on the fixing rod.

Dependent claims

An anti-tamper device, comprising:

a top component, having a first guide portion and a second guide portion;
a reciprocating component, configured for reciprocating between a first position and a second position;
a bottom component, having a fixing rod corresponding to the second guide portion
a rotatable rod, pivotally connected to the fixing rod
a movable sleeve, and
a circuit element;
wherein when the movable sleeve partially sheathes both on the rotatable rod and the fixing rod, and the top component correspondingly is engaged with the bottom component, the rotatable rod is movably engaged with the second guide portion to drive the reciprocating component moving to the first position, so as to trigger the circuit element generating an electronic signal, and to drive the second guide portion pushing the movable sleeve to completely sheath on the fixing rod;
when the top component is disassembled and detached from the bottom component, the rotatable rod is driven to rotate and to form a non-straight angle (non-180°) with the fixing rod, and no longer drives the reciprocating component to move, so as to keep the reciprocating component at the second position.
