Description

Technical Field

[0001] The utility model relates to the field of radiators, and specifically to a sliding clamping fan structure for a radiator. Background Art

[0002] A radiator is a device used to conduct and release heat, and is often applied to computer equipment, mechanical equipment, and heating equipment. The radiator can quickly dissipate the heat generated by the operation of the equipment and maintain the normal operation of the equipment.

[0003] In the prior art, a radiator is usually used in combination with a fan, and the installation and fixation of the fan are basically carried out by wire buckles or screw locking, which is not user-friendly for novice computer assembly. The wire buckle installation requires direct contact with the aluminum fins of the heat sink, and the cross-section of the aluminum fins is sharp and easy to scratch the hands. The screw locking structure is complex and difficult to disassemble and assemble. In order to install the fan on the radiator more safely and simply, a simple and fast installation structure is needed. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a sliding clamping fan structure for a radiator.

[0005] The purpose of the utility model is achieved by the following technical solutions:

[0006] A sliding clamping fan structure for a radiator includes a fixing frame and a clamping screw. The fixing frame is in a long strip shape and is fixed to the side of the radiator. A clamping part is arranged on the outer side of the fixing frame, and the clamping part is integrally formed with the fixing frame and protrudes to one side. The clamping screw is fixed on the fan and is threadedly fixed on the general screw hole of the fan. The clamping screw matches with the clamping part, and the clamping screw is movably connected with the clamping part. When the fan tightens the clamping screw, it can be movably connected and fixed with the radiator equipped with the fixing frame, and can be installed or disassembled by sliding up and down.

[0007] In one embodiment, the inside of the clamping part is hollow, the clamping part has a certain thickness, and there is a space in the middle for the clamping screw to slide in after entering. The upper surface of the clamping part is a clamping surface, and the clamping surface has a certain thickness. The clamping surface can cooperate with the clamping screw to limit the movement range of the clamping screw as needed. The clamping surface is provided with a clamping hole, and the clamping hole is composed of an inlet hole and a limiting hole overlapping. The clamping screw enters the inner side of the clamping part through the inlet hole and slides down and is fixed by the limiting hole. The clamping screw cannot enter or exit through the limiting hole, realizing the quick sliding disassembly and assembly between the fan and the radiator.

[0008] In one embodiment, the engaging screw is provided with a first screw protrusion, a screw connecting column, a second screw protrusion, and a threaded column. The structural order of the engaging screw from top to bottom is the first screw protrusion, the screw connecting column, the second screw protrusion, and the threaded column. The threaded column is connected and fixed to the common screw hole of the fan. The diameter of the first screw protrusion is smaller than the diameter of the entry hole, the diameter of the first screw protrusion is larger than the diameter of the limiting hole, the diameter of the screw connecting column is smaller than the diameter of the limiting hole, and the first screw protrusion enters from the entry hole and slides downward and is restricted by the limiting hole.

[0009] In one embodiment, the engaging hole is provided with fastening protrusions. The distance between the fastening protrusions is smaller than the diameter of the screw connecting column. When the screw connecting column slides from the entry hole into the limiting hole, it will pass through the fastening protrusions. Using the small diameter difference, a suitable resistance is generated when the engaging screw slides through, which can not only remind the user whether the installation is in place, but also prevent the fan from easily sliding out and falling.

[0010] In one embodiment, the diameter of the second screw protrusion is larger than the diameter of the entry hole. Using the second screw protrusion to limit the depth of the engaging screw entering the engaging part can not only control the distance between the fan and the radiator, but also improve the stability when the fan is connected to the radiator.

[0011] In one embodiment, the thickness of the engaging surface is less than or equal to the height of the screw connecting column. When the thickness of the engaging surface is the same as the height of the screw connecting column, the stability when the fan is connected to the radiator can be maintained, preventing the fan from vibrating back and forth and generating noise. When the thickness of the engaging surface is slightly larger than the height of the screw connecting column, it can be deformed and snapped in, which can improve the stability when the engaging screw is connected to the engaging part.

[0012] In one embodiment, the engaging parts are located at the upper and lower ends of the fixing frame, and the engaging surfaces face the fan. Using the upper and lower two engaging parts for snap connection can limit the left - right rotation of the fan and improve the stability when the fan is connected to the radiator.

[0013] In one embodiment, the inner side of the fixing frame is provided with a raised radiator fixing part. The radiator fixing part is provided with a fixing part screw hole, and the radiator fixing part is provided with a fixing screw. The fixing screw passes through the fixing part screw hole and is connected and fixed to the radiator.

[0014] In one embodiment, the radiator is provided with two fixing frames. The two fixing frames are located on both sides of the radiator. The two fixing frames are respectively a left fixing frame and a right fixing frame. The positions of the engaging parts of the left fixing frame and the right fixing frame are different. The engaging part of the left fixing frame is located on the right side of the left fixing frame, and the engaging part of the right fixing frame is located on the left side of the right fixing frame. The four engaging parts of the two fixing frames well adapt to the screw holes at the four corners of the common rectangular fans on the market, realizing a stable connection.

[0015] In one embodiment, the fan is provided with fan screw holes, and the engaging screws are fixed to the four corners of the fan through threaded posts. The first screw protrusion faces the radiator. When using this sliding engagement structure, only the independent engaging screws need to be installed in the fan screw holes, and the fan and the radiator can be quickly and conveniently disassembled and assembled.

[0016] Advantages of the present utility model:

[0017] Due to the adoption of the above technical solution, the present utility model can simply and quickly install the fan on the radiator through the engaging screws fixed on the fan and the fixing brackets fixed on the radiator. During use, only need to screw the engaging screws into the fan screw holes, and then align the engaging screws with the insertion holes and slide them to complete the installation, avoiding scratching hands, being safer and easier to use, and having the advantages of quick disassembly and assembly and simple structure.

[0034] For the embodiments of the present utility model, please refer to Figures 1 to 11 :

[0035] A sliding clamping fan structure for a radiator, comprising a fixing bracket 3 and a clamping screw 4. The fixing bracket 3 is fixed to the side of the radiator 1. A clamping part 5 is provided on the outer side of the fixing bracket 3. The clamping screw 4 is fixed on the fan 2. The clamping screw 4 is matched with the clamping part 5, and the clamping screw 4 is movably connected to the clamping part 5.

[0036] By adopting the above technical solution, the strip-shaped fixing bracket 3 is fixed on both sides of the radiator 1. The upper and lower ends of the outer side of the fixing bracket 3 bulge to one side to form a clamping portion 5. The clamping screw 4 is fixed on the fan 2 through a threaded post 14. The clamping screw 4 matches the shape and position of the clamping portion 5. The protruding end of the clamping screw 4 can enter the clamping portion 5 and be restricted after sliding downward, realizing a movable connection. The fan 2 can be movably connected and fixed to the radiator 1 equipped with the fixing bracket 3 by tightening the clamping screw 4, and can be clamped and installed or taken out and disassembled by sliding up and down.

[0037] Preferably, the inside of the clamping portion 5 is hollow. The upper surface of the clamping portion 5 is a clamping surface 6. The clamping surface 6 is provided with a clamping hole 7. The clamping hole 7 is formed by the overlapping of an entering hole 8 and a limiting hole 9.

[0038] By adopting the above technical solution, the clamping portion 5 has a certain thickness and is hollow inside. The hollow part accommodates the clamping screw 4, enabling the clamping screw 4 to slide after entering. The clamping surface 6 on the upper surface of the clamping portion 5 has a certain thickness, and can cooperate with the clamping screw 4 to limit the movement range of the clamping screw 4 as needed. The clamping hole 7 on the clamping surface 6 is formed by the overlapping of an entering hole 8 and a limiting hole 9. The clamping screw 4 enters the inner side of the clamping portion 5 through the entering hole 8 and is fixed by the limiting hole 9 after sliding downward. The clamping screw 4 cannot enter or exit through the limiting hole 9, realizing the quick sliding disassembly and assembly between the fan 2 and the radiator 1.

[0039] Preferably, the clamping screw 4 is provided with a screw protruding portion one 11, a screw connecting column 13, a screw protruding portion two 12, and a threaded post 14.

The threaded post 14 is connected and fixed to the common screw hole of the fan 2. The diameter of the screw protruding portion one 11 is smaller than the diameter of the entering hole 8 and larger than the diameter of the limiting hole 9. Therefore, the screw protruding portion one 11 can enter the entering hole 8 but cannot slide out in the limiting hole 9.

[0041] Preferably, the clamping hole 7 is provided with a fastening protrusion 10, and the distance between the fastening protrusions 10 is smaller than the diameter of the screw connecting column 13.

[0042] By adopting the above technical solution, the distance between the fastening protrusions 10 of the engaging hole 7 is smaller than the diameter of the screw connection post 13. When the screw connection post 13 slides from the entry hole 8 into the limiting hole 9, it will pass through the fastening protrusions 10. By using a small diameter difference, the engaging screw 4 will have appropriate resistance when sliding through, which can not only remind the user whether the installation is in place, but also prevent the fan 2 from easily sliding out and falling off.

[0043] Preferably, the diameter of the second screw protrusion 12 is larger than the diameter of the entry hole 8.

When the thickness of the engaging surface 6 is the same as the height of the screw connection post 13, the stability when the fan 2 is connected to the radiator 1 can be maintained, preventing the fan 2 from vibrating back and forth to generate noise. When the thickness of the engaging surface 6 is slightly larger than the height of the screw connection post 13, it can be snapped in by deformation, which can improve the stability when the engaging screw 4 is connected to the engaging part 5.

[0047] Preferably, the engaging part 5 is located at the upper and lower ends of the fixing frame 3, and the engaging surface 6 faces the fan 2.

[0049] Preferably, there are raised radiator fixing parts 15 on the inner side of the fixing frame 3. The radiator fixing parts 15 are provided with fixing part screw holes 16, and the radiator fixing parts 15 are provided with fixing screws 17. After the fixing screws 17 pass through the fixing part screw holes 16, they are connected and fixed to the radiator 1.

[0050] By adopting the above technical solution, the raised radiator fixing parts 15 on the inner side of the fixing frame 3 are provided with fixing part screw holes 16. After the fixing screws 17 pass through the fixing part screw holes 16, they are connected and fixed to the radiator 1. The factory can customize the position of the engaging part 5 of the fixing frame 3 according to the common shapes of the fans 2 on the market.

[0051] Preferably, the radiator 1 is provided with two fixing frames 3, and the two fixing frames 3 are located on both sides of the radiator 1.

The four engaging portions 5 corresponding to the two fixing brackets 3 are well adapted to the screw holes at the four corners of the common rectangular fan 2 on the market, realizing a firm connection.

[0053] Preferably, the fan 2 is provided with fan 2 screw holes, and the engaging screws 4 are fixed to the four corners of the fan 2 through the threaded posts 14, and the first screw protrusion 11 faces the radiator 1.
