Anti-disassembling device for electronic products

摘要

An anti-disassembling device for an electronic product includes a case, a linear movement device, a circular movement device and an optical encoder. At least one retractable transmission member is connected to the case. The circular movement device is located in the case and has an encoding disk, which has multiple slots defined therethrough and teeth are defined in the periphery thereof. The at least one retractable transmission member is engaged with the teeth to rotate the encoding disk. The optical encoder has a lighting module which emits light beams through the slots of the encoding disk and a photosensitive module receives the light beams and sends a signal to the storage unit of the electronic product. The retractable device rotates when the electronic product is disassembled.

主权项

1. An anti-disassembling device for an electronic product which has a storage unit, comprising:
a case having a contact face; a linear movement device connected to the contact face and having at least one retractable transmission member on a surface thereof, the linear movement device being merged into the case to stay in a compressed status when the contact face is fixed on an object, the linear movement device protruding from the case and being in a free status when the contact face is separated from the object; a circular movement device located in the case and having an encoding disk which has multiple slots in a circular arrangement on the encoding disk, the encoding disk having teeth defined in a periphery of the encoding disk and the at least one retractable transmission member engaged with the teeth, the encoding disk being rotated when the linear movement device moves linearly and co-moves the teeth, and an optical encoder located corresponding to the encoding disk and having a lighting module which emits light beams to the encoding disk, a photosensitive module receiving the light beams through the encoding disk and having an output end which is connected with the electronic product, the output end adapted to send a signal to the storage unit when the photosensitive module receives the light beams from the lighting module through the slot of the encoding disk.
