Abstract: A fan-fixing device for fixing a fan on an installation panel which has a plurality of holes includes a body, a driving part and an elastic assembly. The body has a fixing portion for fixing the fan, at least one track is formed on a side thereof, and at least one first combined part is disposed on an opposite side thereof, wherein the combined part penetrates at least one of the holes. The driving part slidably disposed on the track. The driving part further has at least one second combined part, which penetrates at least another one of the holes. The elastic assembly is arranged between the body and the driving part. As a result, the first combined part and the second combined part can be fixed in the holes via force pushing the driving part, and can be departed from the holes via releasing the force.

Abstract: A screwless fixing assembly disposed on a frame is provided, which includes a fixed member, a movable member, an elastic member, and a positioning device. The fixed member is fixed on the frame and has an opening form thereon. The movable member is movably disposed to the fixed member and has a pin to pass through a through hole of the frame. The elastic member is provided for pushing the movable member to move away from the frame. The positioning device is disposed on the movable member and protrudes on the fixed member through the opening, for being selectively engaged with the fixed member at a first position and a second position, so as to move the pin to leave or inserted into the through hole. An electronic device is fixed on the other side of the frame by the pin passing through the through hole.

Abstract: A buckling assembly and a casing structure using the same are described. The buckling assembly is used for fixedly locking a buckled member which may be a panel or a casing. The buckling assembly includes a guide rail, a locking seat, and a rotary handle. The guide rail is fixed on an inner side of the casing or the panel. The locking seat is slidably disposed on the guide rail for locking the buckled member. The rotary handle is pivotally affixed to the guide rail and is turned to drive the locking seat move on the guide rail, so as to lock or release the buckled member.

Abstract: A structure of a liftable cover includes a cover having a pivoting end and a covering seat that allows the cover to be disposed thereon. The covering seat is formed thereon with a notch. Both sides of the notch are formed with a sidewall for the covering seat respectively. The notch is hollowed in the vertical direction. Both ends of the pivoting end of the cover are pivotally provided with a pivotal sliding block. The sidewalls on both sides of the covering seat are provided with a sliding trough to correspond to the pivotal sliding block respectively. The two pivotal sliding blocks slide into the two sliding troughs and are connected thereto respectively. Via the indirect pivotal connection of the two pivotal sliding blocks, components can be replaced and assembled in a rapid and convenient manner.
