[0028] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0029] like Figures 1-5As shown, a support frame and cooling fan in one embodiment of the present invention include a support frame body 1 and a cooling fan body 10. The cooling fan body 10 is mounted on the support frame body 1. The support frame body 1 supports the cooling fan body 10 and can adjust the orientation of the cooling fan body 10 to improve the cooling effect of the cooling fan body 10.

[0030] like Figures 2-3 As shown, the support frame body 1 includes a first support plate 2, on which a sliding groove 201 is formed. Multiple sliders 4, matching the sliding groove 201, are slidably connected to the first support plate 2. Each slider 4 has a slotted hole 402. When installing the first support plate 2, the slotted holes 402 are aligned with the mounting holes, and the plate is then fixed with bolts.

[0031] Generally, there are two sliders 4, each corresponding to one of the two holes. The two sliders 4 can also effectively fix the support frame body 1.

[0032] like Figures 2-3 As shown, a limiting strip 3 is fixedly connected to the side wall of the first support plate 2, and a groove 401 matching the limiting strip 3 is provided on the slider 4. The slider 4 is locked in the slide groove 201 by the cooperation of the groove 401 and the limiting strip 3, and is not easy to fall off the slide groove 201.

[0033] like Figure 3 As shown, the first support plate 2 is also provided with multiple indicator marks 5. The outer diameter of the indicator mark 5 located in the middle is larger than that of the other indicator marks 5. The indicator mark 5 with the largest outer diameter indicates the center position of the first support plate 2. By judging the distance between the slider 4 and the indicator mark 5 with the largest outer diameter, the two sliders 4 are symmetrically arranged on the first support plate 2, so as to avoid the situation where the bolt fixing one of the sliders 4 is affected by excessive force due to the tilt of the first support plate 2, which affects its service life.

[0034] like Figures 2-3 As shown, a second support plate 7 is rotatably connected to the lower end of the first support plate 2. The second support plate 7 has multiple preset holes 701, through which the cooling fan body 10 can be mounted. Specifically, a connecting rod 8 is fixedly connected to the upper end of the second support plate 7, and a protrusion 6 is fixedly connected to the first support plate 2. The protrusion 6 has a first through hole 601 that matches the threaded hole 802. The second support plate 7 is rotatably connected to the first support plate 2 through the cooperation of the connecting rod 8 and the first through hole 601.

[0035] One end of the connecting rod 8 is fixedly connected to a stop block 801, and the end of the connecting rod 8 away from the stop block 801 has a threaded hole 802. A fastening bolt 9 matching the first through hole 601 is installed on the protrusion 6. The fastening bolt 9 passes through the first through hole 601 and is threadedly connected to the threaded hole 802. By tightening the fastening bolt 9, the connecting rod 8 can be rotated to a certain angle and then locked. The cooling fan body 10 is installed on the support frame body 1, and the airflow direction of the cooling fan body 10 can be changed according to actual needs to achieve the best heat dissipation effect.

[0036] When using the support frame body 1, it is first necessary to install the support frame body 1 on the equipment. By sliding the position of the slider 4 in the slide groove 201, the groove 401 is aligned with the hole of the equipment. The slider 4 and the equipment are fixed with bolts. The position of the first support plate 2 is adjusted by sliding to make the two sliders 4 as centered as possible in the slide groove 201. After adjusting the position of the first support plate 2, the bolts are tightened. Then, the cooling fan body 10 is installed on the second support plate 7, and the fastening bolts 9 are loosened. The cooling fan body 10 is rotated to align the orientation of the cooling fan body 10 with the electronic component that needs cooling. After confirming the orientation of the cooling fan body 10, the fastening bolts 9 are tightened to lock the connecting rod 8 and the protrusion 6. The connecting rod 8 can no longer rotate in the first through hole 601.

[0037] like Figures 4-5 As shown, the cooling fan body 10 includes an outer frame 11, and four connecting portions 12 are fixedly connected to the outer frame 11, located at the four corners of the outer frame 11. Each connecting portion 12 has at least two second through holes 1201 and a third through hole 1202 that matches the second through holes 1201. The second through holes 1201 and the third through holes 1202 are interconnected, and their axes are on the same straight line.

[0038] like Figures 4-5 As shown, a limiting groove 1203 is provided on the inner wall of the third through hole 1202, and a nut 14 that matches the limiting groove 1203 is fixedly connected to the connecting part 12.

[0039] The connecting part 12 is generally used when adding a cooling fan body 10. The cooling fan body 10 is threaded onto the equipment by a bolt passing through the second through hole 1201. When it is necessary to install a support frame body 1 on the connecting part 12 to add a cooling fan body 10, the groove 401 of the cooling fan body 10 can be directly aligned with the third through hole 1202, and then the connecting part 12 and the support frame body 1 are fixed by bolts and nuts 14. Then the cooling fan body 10 is installed on the added support frame body 1.

[0040] The above-mentioned usage scenarios are generally used in computer cases. When the electronic components inside the case are updated, the original cooling fan body 10 can no longer meet the heat dissipation requirements. The cooling fan body 10 can be added by means of the support bracket body 1 without disassembling the cooling fan body 10. The operation is simple and convenient. Moreover, with the cooperation of the support bracket body 1, it can adapt to different specifications of cooling fan body 10 and can also control the orientation of the cooling fan body 10, thereby improving the heat dissipation effect of the cooling fan body 10.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
