DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides Figure 1-3 A stably installed computer cooling fan is shown, comprising a fixing frame a1 and a fixing frame b2 installed at the rear side of the fixing frame a1;

[0026] A working chamber 4 is fixedly connected between the fixed frame a1 and the fixed frame b2;

[0027] A driving shaft 3 is arranged inside the working chamber 4;

[0028] A plurality of fan blades 10 are fixedly connected to the circular outer wall of the driving shaft 3 at equal intervals. A power cord 8 is arranged on the left side of the driving shaft 3. A connector 9 is fixedly connected to the outer wall of the left end of the power cord 8 to electrically connect with an external power source. Front and rear through-going mounting holes 6 are provided at the four corners of the front end outer walls of the fixed frame a1 and the fixed frame b2. The mounting holes 6 on the fixed frame a1 and the fixed frame b2 are aligned with the corresponding holes on the chassis. The fixed frame a1 and the fixed frame b2 are fixed to the chassis by external fixing screws. Then, the connector 9 at the other end of the power cord 8 is connected in series and plugged into the corresponding power plug on the mainboard. After power is turned on, the power cord 8 provides electricity to rotate the driving shaft 3, driving the fan blades 10 to rotate to dissipate heat from the chassis.

[0029] Fixed pads 13 are provided between the inner walls of the front and rear ends of the fixed frame a1 and the fixed frame b2 and near the left and right sides respectively to clamp the power cord 8. A limiting hole 15 is opened at the center of the fixed pad 13 to limit the position of the power cord 8. A card slot 12 is opened on the outer wall of the upper end of the fixed pad 13 to guide the power cord 8 to move to the inside of the limiting hole 15. After the power cord 8 is connected in series, the power cord 8 can be abutted against the card slot 12 and pressed downward to the inside of the limiting hole 15 inside the fixed pad 13 to fix the position of the power cord 8.

[0030] like Figure 2 As shown, the lower end outer wall of the fixed pad 13 is fixedly connected to the limit frame 14, and connecting rods 16 are fixedly connected between the front and rear end outer walls of the limit frame 14 and the front and rear end inner walls of the fixed frame a1 and the fixed frame b2 to limit the position of the limit frame 14. The fixed pad 13 is made of soft rubber material, and the limit frame 14 and the connecting rod 16 are made of polyethylene plastic material to reduce their own weight.

[0031] The position of the limit frame 14 is fixed by the connecting rod 16, thereby limiting the position of the fixing pad 13 clamping the power cord 8. The fixing pad 13 made of soft rubber material can increase the friction between the power cord 8 and prevent the power cord 8 from slipping out of the fixing pad 13.

[0032] like Figure 3 and Figure 4 As shown, a fixing rod a18 is fixedly connected between the inner walls of the front and rear ends of the fixing frame a1 and the fixing frame b2 near the right side, a positioning groove 17 opening to the right is provided inside the outer wall of the right end of the fixing rod a18, a fixing rod b20 is fixedly connected between the inner walls of the front and rear ends of the fixing frame a1 and the fixing frame b2 near the left side, a positioning block 21 is fixedly connected to the outer wall of the left end of the fixing rod b20 so as to be clamped to the left inside the positioning groove 17, a magnetic head 19 is fixedly connected to the outer wall of the left end of the positioning block 21, and a magnetic plate is fixedly connected to the inside of the positioning groove 17 so as to perform magnetic adsorption with the magnetic head 19.

[0033] When multiple cooling fans are connected, the positioning block 21 at the left end of the fixing rod b20 can be inserted into the positioning groove 17 opened inside the fixing rod a18 on another cooling fan for clamping, and the magnetic head 19 at the left end of the positioning block 21 can be magnetically adsorbed to the magnetic plate inside the positioning groove 17, thereby assisting in fixing the positions of the multiple cooling fans.

[0034] like Figure 1 As shown, the circular inner wall of the fixed frame a1 is fixedly connected to the fixed frame b11, the circular inner wall of the fixed frame b2 is fixedly connected to the fixed frame a5 to limit the position of the drive shaft 3, the four corners of the outer walls at the front and rear ends of the fixed frame a1 and the fixed frame b2 are fixedly connected with shock-absorbing pads 7, the inside of the drive shaft 3 is fixedly connected to the drive motor, and a clamping groove is opened on the leftmost side of the inner part of the front end outer wall of the fixed frame a5 to limit the position of the local power line 8.

[0035] The positions of the drive shaft 3 and the drive motor are limited by the fixing frame a5 and the fixing frame b11. The vibration generated when the drive motor is working can be mitigated by the shock-absorbing pad 7 in contact with the inner wall of the chassis to reduce the amplitude of the vibration, thereby reducing the generation of noise. The clamping groove can clamp the power cord 8 at a position close to the drive shaft 3 to prevent the power cord 8 from directly contacting the fan blades 10 during rotation.

[0036] The implementation principle of this embodiment is: align the mounting holes 6 on the fixed frame a1 and the fixed frame b2 with the corresponding holes on the chassis, fix the fixed frame a1 and the fixed frame b2 on the chassis by external fixing screws, and then connect the connector 9 at the other end of the power cord 8 in series and plug it into the corresponding power plug on the mainboard. After power is turned on, the power cord 8 provides power to rotate the drive shaft 3, driving the fan blades 10 to rotate for chassis heat dissipation. After the power cord 8 is connected in series, the power cord 8 can be abutted against the card slot 12 and pressed down to the limit hole 15 inside the fixing pad 13 to fix the position of the power cord 8.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
