Description

Technical Field

[0001] The utility model relates to the technical field of chassis cooling fans, in particular to a chassis cooling fan installation structure. Background Art

[0002] As a part of computer accessories, the main function of the computer case is to place and fix various computer accessories, and play a supporting and protective role. In addition, the computer case has an important role in shielding electromagnetic radiation. Since the various electronic components inside the computer case generate quite a lot of heat, fans are generally installed on the computer case for heat dissipation.

[0003] In the related art, reference may be made to the Chinese patent with the announcement number CN216014198U, which specifically discloses a heat dissipation structure of a computer case. The heat dissipation structure of the computer case includes a body, an air inlet is provided on the rear end surface of the body, dustproof cotton is fixedly installed on the air inlet, a heat dissipation fan mounting seat is fixedly connected to the air inlet inside the body, a card slot is provided on the surface of the heat dissipation fan mounting seat, the heat dissipation fan mounting seat is fixedly connected to the heat dissipation fan base through a buckle assembly, and a heat dissipation fan is fixedly installed inside the heat dissipation fan base.

[0004] By squeezing the card block button, the connecting frame is driven to move backward, at this time the first spring is deformed, and the connecting frame moves backward to drive the first card block and the second card block to move. When it moves to a certain distance, the first locking barb and the second locking barb are separated from the buckle base, the second spring recovers the deformation to make the first locking barb and the second lock expand outward, thereby reaching a locked state. By squeezing the first card block top and the second card block top, the first locking barb and the second locking barb are retracted inwardly. When retracted to a certain position, the first spring recovers the deformation to push the buckle button forward, driving the connecting frame to move forward, thereby driving the first card block and the second card block to move, so that the first locking barb and the second lock move into the buckle base, and the unlocked state is reached.
