Description

Technical Field

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

[0002] A computer fan, also known as a cooling fan, is generally used for heat dissipation and is provided for a radiator and a computer case. Computer fans are divided into case fans and CPU fans. When installing an existing computer cooling fan, such as a computer CPU fan installation structure in patent CN212484297U3, a clamping head is squeezed into the inside of a clamping column, thereby increasing the outer diameter of the clamping column, so as to fix a fixing column on a round hole. However, screws are still needed for fixation during installation. However, the space in a computer case is narrow, making it difficult to operate and the installation rather cumbersome. Content of the Utility Model

[0003] The purpose of the utility model is to solve the defects existing in the prior art, and to provide an installation structure of a computer cooling fan.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] Design an installation structure of a computer cooling fan, including a fan bracket. A fan is arranged in the middle of the fan bracket. Installation holes are opened at the four corners of the fan bracket. Fixing rods are inserted into the installation holes. The fixing rods pass through the computer case shell. A cylinder is arranged at the end of the fixing rod. A second clamping groove in the axial direction is opened on the cylinder. A rotating shaft is slidably arranged in the fixing rod. A convex block is arranged at the end of the rotating shaft. A wedge block is arranged in the inner wall of the cylinder. The wedge block abuts against the convex block.

[0006] Preferably, a washer and a rubber pad are sleeved on the top of the fixing rod. A cam is rotatably arranged at the top of the rotating shaft. The cam abuts against the washer.

[0007] Preferably, a butterfly nut is threadedly connected to the top of the rotating shaft.

[0008] Preferably, a ring-shaped first clamping groove is opened on the outer wall of the cylinder. The opening of the computer case shell is clamped into the first clamping groove.

[0009] Preferably, a limiting ring is arranged on the outer wall of the fixing rod. The limiting ring is located in the middle of the fan bracket.

[0010] Preferably, an arc-shaped rotating handle is integrally formed on the cam.

[0011] An installation structure of a computer cooling fan proposed by the present utility model has the beneficial effects that: by setting a cam structure or a wing nut, when installing the fan, the fan bracket is attached to the inner wall of the chassis, the end of the fixing rod is inserted into the positioning hole of the chassis, and then the cam is rotated. The rotating shaft moves, and the convex block presses the wedge block, and the cylinder at the end of the fixing rod expands and is fixed to the opening of the chassis. The installation process is simple and easy to operate, without the need to use tools such as screwdrivers, and can be operated by hand, which is suitable for installation in narrow spaces.
