[0002] A fixing device for a CPU radiator of a computer motherboard generally consists of parts such as a radiator tray, a radiator bracket, and a protection component.

[0003] The patent with the patent publication number CN221465950U relates to a mounting bracket for a CPU radiator. A fixing frame is fixedly connected to one side surface of the CPU radiator mounting bracket. For this CPU radiator fixing device, through the settings of the CPU radiator mounting bracket, the fixing frame, plastic fasteners, through holes, support rods, baffles, first fixing blocks, first threaded holes, bolts, second fixing blocks, second threaded holes, first pressing plates, and second pressing plates, during use, first insert the plastic fasteners into the mounting holes on the motherboard, and then install the CPU radiator mounting bracket. After that, insert the support rods into the through holes until they reach the holes in the middle of the plastic fasteners to fix the plastic fasteners. After fixing the plastic fasteners, place the first pressing plate above the CPU radiator mounting bracket to align the first threaded hole with the second threaded hole.

[0014] The present invention provides a fixing device for a computer motherboard CPU radiator. It has the following beneficial effects:

[0015] (1) For the fixing device of the computer motherboard CPU radiator, by rotating the protection disk, the protection groove is aligned with the protection rod and the limit on the protection disk is released. The protection disk can effectively reduce the loosening of the radiator body caused by external force or human operation error, thereby increasing the stability of the entire installation frame, and further ensuring the normal operation of the computer during long-term use. By moving the limiting plate downward to contact the front side of the radiator body and restoring the limit on the radiator body, the precise docking can ensure that the radiator body is more stable after installation and is not prone to loosening, thereby avoiding the problem of excessive local pressure on the radiator body.

[0016] (2) For the fixing device of the computer motherboard CPU radiator, by moving the anti-vibration plate towards the radiator body to contact the anti-vibration groove and limit the radiator body. When the radiator body operates for a long time, it will generate small displacements due to vibration, which will affect its heat dissipation efficiency. Through the design of the anti-vibration plate and the anti-vibration groove, the radiator body can be kept in the best contact position, thereby maximizing the heat dissipation effect of the radiator body.

[0017] (3) For the fixing device of the CPU radiator on the computer motherboard, the slow rotation of the deceleration plate enables the anti-shake rod to move and reset slowly. The slow movement and reset of the anti-shake rod cause the anti-shake plate to reset slowly, releasing the limit on the radiator body. The slow reset of the anti-shake rod can gradually release the restriction on the radiator body, thereby avoiding the slipping of the radiator body caused by too fast release action, and reducing the risk of damage to the radiator or CPU.

[0018] (4) For the fixing device of the CPU radiator on the computer motherboard, the connecting plate moves towards the fixing plate and contacts the power cord, and fastens the contact point between the power cord and the installation frame. Through the movement and fastening of the connecting plate, it can ensure the stable connection of the contact point between the power cord and the installation frame, thereby avoiding the loosening or poor contact of the power cord caused by factors such as vibration and external force during use, and improving the stability of power transmission.

[0019] (5) For the fixing device of the CPU radiator on the computer motherboard, the rack is extruded by the gear and moves towards the placement frame to secondarily fasten the power cord, thereby preventing the power cord from being damaged due to excessive pulling. As the pulling force increases, the extrusion force of the rack on the power cord can effectively enhance the tensile strength of the power cord, thereby avoiding the power cord from being stretched or damaged, and extending the service life of the power cord.

Detailed implementation mode

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1 - 7 , an embodiment of the present invention is: a fixing device for a computer motherboard CPU radiator, including a bottom plate 1. A connecting piece 2 is arranged on the top of the bottom plate 1. A docking plate 3 is fixedly installed on the top of the bottom plate 1. An installation frame 4 is fixedly installed on the top of the docking plate 3. A radiator body 5 is arranged on the inner wall of the installation frame 4. A moving rod 6 slidably penetrates through the inner and outer walls of the installation frame 4. A moving plate 7 is fixedly installed on the front side of the moving rod 6. A U-shaped plate 8 is fixedly installed on the surface of the installation frame 4. A U-shaped rod 9 is fixedly installed on the top of the installation frame 4. A limiting plate 10 is slidably installed on the circumferential surface of the U-shaped rod 9. A limiting spring 11 is arranged between the limiting plate 10 and the installation frame 4. The limiting plate 10 penetrates through the top of the installation frame 4. A protection disc 12 is rotatably installed on the top of the limiting plate 10. A protection groove 13 is opened on the circumferential surface of the protection disc 12. A protection rod 14 is fixedly installed on the circumferential surface of the U-shaped rod 9. A connection hole is opened on the right side of the installation frame 4. Through the protection disc 12, the loosening of the radiator body 5 caused by external force or human operation error can be effectively reduced, thereby increasing the stability of the entire installation frame 4. Through precise docking, it can be ensured that the radiator body 5 is more stable after installation and is not easy to loosen.

[0030] The protection disc 12 contacts the bottom of the protection rod 14. The limiting plate 10 contacts the front side of the radiator body 5. A first spring is arranged between the moving plate 7 and the installation frame 4. The moving plate 7 can be driven to reset through the first spring.

[0031] A first clockwork spring is arranged between the protection disc 12 and the limiting plate 10. One end of the first clockwork spring is arranged at the bottom of the protection disc 12, and the other end is arranged at the top of the limiting plate 10. The protection disc 12 can be driven to reset by the first clockwork spring. The bottom of the limiting plate 10 is set as an inclined surface, and the front side of the U-shaped plate 8 is set as an inclined surface.

[0032] During the operation of this embodiment: when the radiator body 5 needs to be cleaned, manually rotate the protection disc 12. The rotation of the protection disc 12 squeezes the first clockwork spring. The first clockwork spring deforms and stores energy under the extrusion of the protection disc 12. At the same time, the rotation of the protection disc 12 aligns the protection groove 13 with the protection rod 14. After the protection groove 13 is aligned with the protection rod 14, the protection rod 14 releases the limit on the protection disc 12. After the limit on the protection disc 12 is released, manually pull the limiting plate 10 upward. The upward movement of the limiting plate 10 pulls the limiting spring 11. The limiting spring 11 deforms and stores energy under the pull of the limiting plate 10. At the same time, the limiting plate 10 moves upward to disengage from the contact with the radiator body 5. After the radiator body 5 disengages from the contact with the limiting plate 10, the moving plate 7 moves forward under the elastic force of the first spring. The forward movement of the moving plate 7 pushes out a part of the radiator body 5. After the radiator body 5 is cleaned, the radiator body 5 is inserted into the installation frame 4. The radiator body 5 entering the installation frame 4 squeezes the moving plate 7. The moving plate 7 moves backward under the extrusion of the radiator body 5. The backward movement of the moving plate 7 squeezes the first spring. The first spring deforms and stores energy under the extrusion of the moving plate 7. At the same time, after the radiator body 5 moves to the original position, the limiting plate 10 moves downward under the elastic force of the limiting spring 11. The downward movement of the limiting plate 10 contacts the front side of the radiator body 5 and resumes the limit on the radiator body 5.

[0033] Please refer to Figures 1 - 7 , on the basis of the above embodiment, in another embodiment of the present invention, an anti-vibration component for preventing the radiator body 5 from shaking excessively is arranged on the right side of the installation frame 4, and a protection component for preventing the cable from being excessively pulled is arranged on the right side of the installation frame 4. The anti-vibration component includes a placement frame 151, an anti-vibration rod 152, an anti-vibration plate 153, an anti-vibration groove 154, a deceleration hole 155, a deceleration rod 156 and a deceleration plate 157. A placement hole is opened on the right side of the installation frame 4. The placement frame 151 is fixedly installed on the right side of the installation frame 4. The anti-vibration rod 152 slidably penetrates the inner and outer walls of the placement frame 151. The anti-vibration plate 153 is fixedly installed on the left side of the anti-vibration rod 152. The anti-vibration groove 154 is opened on the right side of the radiator body 5. The deceleration hole 155 is opened on the right side of the placement frame 151. The deceleration rod 156 is rotatably installed on the inner wall of the deceleration hole 155. The deceleration plate 157 is fixedly installed on the circumferential surface of the deceleration rod 156. Through the design of the anti-vibration plate 153 and the anti-vibration groove 154, the radiator body 5 is kept in the best contact position, thereby maximizing the heat dissipation effect of the radiator body 5.

[0034] A second clockwork spring is arranged between the speed reduction rod 156 and the speed reduction plate 157. One end of the second clockwork spring is arranged on the circumferential surface of the speed reduction rod 156, and the other end is arranged on the inner wall of the speed reduction hole 155. The second clockwork spring can drive the speed reduction rod 156 to reset. An L-shaped plate 158 is fixedly installed on the right side of the anti-sway plate 153. The anti-sway plate 153 is in contact with the inner wall of the placement hole. The anti-sway rod 152 can only slowly move back to its original position, so that the anti-sway plate 153 slowly resets to release the limit on the radiator body 5. The slow reset of the anti-sway rod 152 can gradually release the restriction on the radiator body 5, thereby avoiding the radiator body 5 from slipping due to too fast a release action. The second clockwork spring has a relatively large elastic coefficient.

[0035] A second spring is arranged between the anti-sway plate 153 and the placement frame 151. The second spring can drive the anti-sway plate 153 to reset. The front side of the anti-sway plate 153 is set as an inclined surface, and the anti-sway plate 153 is in contact with the bottom of the limiting plate 10.

[0036] The protection component includes a connecting plate 161, a fixing plate 162 and a stabilizing rod 163. The connecting plate 161 is slidably installed on the right side of the installation frame 4. The fixing plate 162 is fixedly installed on the right side of the installation frame 4. The stabilizing rod 163 is fixedly installed on the right side of the installation frame 4. A gear 164 is rotatably installed on the circumferential surface of the stabilizing rod 163. A rack 165 is slidably installed on the right side of the fixing plate 162. An anti-pulling groove 166 is formed on the front side of the rack 165. A stabilizing groove 167 is formed on the rear side of the connecting plate 161. By moving and fastening the connecting plate 161, it is possible to avoid the power cord from loosening or poor contact due to factors such as vibration and external force during use.

[0037] The gear 164 meshes with the rack 165. The gear 164 is made of polycarbonate with a relatively high coefficient of friction. The polycarbonate gear 164 can increase the friction between the gear 164 and the power cord. A third spring is arranged between the connecting plate 161 and the installation frame 4. The third spring can drive the connecting plate 161 to reset.

[0038] A power cord is arranged between the connecting plate 161 and the fixing plate 162. The power cord is in contact with the inner wall of the connection hole and the gear 164. As the pulling force increases, the squeezing force of the rack 165 on the power cord can effectively enhance the tensile strength of the power cord, thereby avoiding the power cord from being stretched or damaged, and extending the service life of the power cord.

[0039] During the operation of this embodiment: The limiting plate 10 moves downward to contact the anti-sway plate 153 and squeeze the inclined surface of the anti-sway plate 153. The anti-sway plate 153 moves toward the radiator body 5 under the extrusion of the limiting plate 10. The anti-sway plate 153 moves toward the radiator body 5 and pulls the second spring. The second spring deforms and stores energy under the pull of the anti-sway plate 153. At the same time, the anti-sway plate 153 moves toward the radiator body 5 to contact the anti-sway groove 154 and limit the radiator body 5. When the limiting plate 10 moves upward, the limiting plate 10 moves upward to disengage from the contact with the anti-sway plate 153. After the anti-sway plate 153 disengages from the contact with the limiting plate 10, the anti-sway plate 153 moves to the right to reset under the elastic force of the second spring. The anti-sway plate 153 moves to the right to reset and drives the anti-sway rod 152 to move. The anti-sway rod 152 moves to contact the deceleration plate 157 and squeeze the deceleration plate 157. The deceleration plate 157 rotates under the extrusion of the anti-sway rod 152. The deceleration plate 157 rotates to drive the deceleration rod 156 to rotate. The deceleration rod 156 rotates to squeeze the second clockwork spring. The elastic coefficient of the second clockwork spring itself is relatively large, and it can only slowly deform when being squeezed by the deceleration rod 156. The slow deformation of the second clockwork spring makes the deceleration rod 156 and the deceleration plate 157 rotate slowly. The slow rotation of the deceleration plate 157 makes the anti-sway rod 152 can only slowly move to reset. The anti-sway rod 152 can only slowly move to reset, so that the anti-sway plate 153 slowly resets to release the limit on the radiator body 5.

[0040] The anti-sway plate 153 moves toward the radiator body 5 and drives the L-shaped plate 158 to move. The L-shaped plate 158 moves to contact the connecting plate 161 and squeeze the connecting plate 161. The connecting plate 161 moves toward the fixing plate 162 under the extrusion of the L-shaped plate 158. The connecting plate 161 moves toward the fixing plate 162 and squeezes the third spring. The third spring deforms and stores energy under the extrusion of the connecting plate 161. At the same time, the connecting plate 161 moves toward the fixing plate 162 to contact the power cord and fasten the contact point between the power cord and the installation frame 4. If the power cord of the radiator body 5 is pulled by an external force, the power cord moves to the right under the external force. The power cord moves to the right to contact the gear 164 and squeeze the gear 164. The gear 164 rotates under the pull of the power cord. The gear 164 rotates to squeeze the rack 165. The rack 165 moves toward the placement frame 151 under the extrusion of the gear 164 and fastens the power cord again, thereby preventing the power cord from being damaged due to excessive pulling.
