  • Patent number: 7546998
    Abstract: A fan fixing structure for holding a fan and fixing it on a housing is provided. The structure includes a guide piece secured on the housing, a cover plate, a resilient piece and a positioning element. The cover plate is pivoted on the guide piece and pivotedly rotates between an open position and a closed position. When the cover plate is in the open position, it further shifts to an engaged position. Therefore, the fan is moved into the guide piece by the guidance of the guide piece, and then fixed on the housing by pivotedly rotating the cover plate to the closed position and moving it to the engaged position. Meanwhile, the fan is stably located in the engaged position by the proper arrangement of the resilient piece and the positioning element. The object of easily assembling, fixing and disassembling the fan without tools is achieved.
