[0002] A heat dissipation fan is a cooling device widely used in electronic equipment, mainly used to help dissipate the heat generated inside the equipment to maintain the normal working temperature of the equipment. It produces airflow through rotating blades, taking away hot air from the equipment, while introducing cooler air, thereby achieving the effect of cooling.

[0003] When installing the heat dissipation fan, it is necessary to ensure that the screw can accurately pass through the reserved hole position on the fan and the case. If the hole position is not aligned, or there is a slight deviation between the fan and the case, the screw may not be installed smoothly.

[0018] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same figure marks or the same component names, wherein the disclosure contained in the whole specification can be transferred to the same parts with the same figure marks or the same component names in the meaning. The selected position description in the specification, for example, up, down, lateral and the like, also refers to the directly described and shown drawings and is transferred to the new position in the meaning when the position changes.

[0019] Embodiment: a convenient installation heat dissipation fan of screwless fixing structure, such as Figs. 1-3As shown, including the installation frame 1, fan body 2, clamping piece 3, spring 4, connecting block 5, fixed frame 6, sliding block 7, fixed block 8, gasket 9, elastic block 10 and mounting plate 11, the installation frame 1 inside clamping piece 3, in the installation frame 1 inside left and right sides, all above and below symmetrically square mouth is set up, each square mouth all connects with spring 4, one end of spring 4 is fixed in the installation frame 1 square mouth inside, the other end of spring 4 all connects with connecting block 5, the inner side of connecting block 5 all connects with clamping piece 3, clamping piece 3 can extend to the inside of installation frame 1, the outside of fan body 2 is set up with the slot of clamping piece 3, realize the clamping fixed with fan body 2, in the inside of installation frame 1 with left-right symmetry clamping piece 3, fixed frame 6 inside sliding connection has sliding block 7, sliding block 7 and the corresponding contact surface of fan body 2 are connected, in the front side of installation frame 1, with left-right symmetry connecting has fixed block 8, the middle part of fixed block 8 is designed as triangular slope, this design makes when installing fan body 2 to the back, the fixed frame 6 on fan body 2 can smoothly contact with the middle part of fixed block 8, and due to the guidance of slope and embed in the middle part of fixed block 8, realize further fixed, in the front side of installation frame 1 above and below symmetrically connecting has gasket 9, gasket 9 can fill the joint gap between fan body 2 and installation frame 1, improve the overall sealing performance, in the inside of installation frame 1 above and below symmetrically connecting has elastic block 10, in the process of installing fan body 2, elastic block 10 can produce certain elastic deformation, so that the connection between fan body 2 and installation frame 1 is more closely, further improve the stability of installation, in the left and right sides of installation frame 1 all connect with mounting plate 11, mounting plate 11 is used to fix the whole cooling fan to the required position or equipment.

[0020] When the cooling fan needs to be installed, first, the fan body 2 is aligned with the opening of the installation frame 1, ready for installation. During installation, the fixed frame 6 on the back side of the fan body 2 will first contact the fixed block 8 on the front side of the installation frame 1. Because the middle part of the fixed block 8 is designed as a triangular slope, this design allows the fixed frame 6 to smoothly slide along the slope until it reaches the middle position of the fixed block 8. At this time, the fixed frame 6 is caught by the fixed block 8, achieving the preliminary positioning of the fan body 2 inside the installation frame 1.

[0021] As the fan body 2 continues to push in, the clamping piece 3 inside the installation frame 1 will be extruded by the fan body 2. Because the clamping piece 3 is connected to the installation frame 1 through the connecting block 5 and the spring 4, the spring 4 will be compressed, and at the same time the clamping piece 3 will extend to the inside of the installation frame 1. When the fan body 2 reaches the predetermined position, the clamping piece 3 will be clamped into the corresponding clamping slot or hole on the fan body 2 under the action of the spring 4, thereby achieving firm connection between the fan body 2 and the installation frame 1.

[0022] In addition, the elastic block 10 on the inner side of the mounting frame 1 will be elastically deformed during the installation of the fan body 2, thereby closely fitting the surface of the fan body 2. This close fitting not only improves the stability of the installation, but also helps to reduce the vibration and noise of the fan during operation. At the same time, the sealing gasket 9 on the front side of the mounting frame 1 can fill the joint gap between the fan body 2 and the mounting frame 1, preventing air or dust from entering from the gap, thereby improving the overall sealing performance.

[0023] Finally, through the mounting plates 11 on the left and right sides of the mounting frame 1, the entire cooling fan can be fixed to the desired position or equipment using fasteners such as bolts and nuts, completing the installation process.

[0024] In summary, the convenient installation of the screw-free fixing structure of the cooling fan achieves the purpose of quickly and stably installing the fan body 2 without screws, while improving the convenience and efficiency of the installation.
