[0015] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0016] A cooling fan protection bracket, such as Figure 1 、 2As shown in Figures 3 and 4, the box body 1 includes a box body 1 on which a cooling fan 100 is fixedly installed. The box body 1 has openings on both sides, and dust screens 2 are respectively provided at the openings on both sides of the box body 1. Side panels 3 are respectively hingedly provided at the openings on both sides of the box body 1. The two side panels 3 close the openings on both sides of the box body 1. The sides of the two side panels 3 that are close to each other fit the corresponding opening sides of the box body 1. A driving mechanism for driving the side panels 3 to rotate is provided on the box body 1. The utility model has a simple structure and an ingenious design. The side panels 3 can not only protect the cooling fan 100, but also serve as support legs to support the cooling fan 100. It can meet market demand and is suitable for promotion. When the jacks 1 are in the upright position, the left jacks 3 are in the upright position, and the right jacks 3 are in the upright position, so that the jacks 1 are in the upright position, and the left jacks 3 are in the upright position, so that the jacks 1 are in the upright position, and the right jacks 3 are in the upright position, so that the jacks 1 are in the upright position, and the right jacks 3 are in the upright position, so that the jacks 1 are in the upright position, and the right jacks 3 are in the upright position, so that the jacks 1 are in the upright position, and the

[0017] Specifically, as shown in the figure, the driving mechanism described in this embodiment includes two rotating shafts 20, which correspond to the side plates 3 one by one. The rotating shafts 20 are rotatably installed on the box body 1 through several bearing seats. The outer peripheries of the rotating shafts 20 are rotatably connected to the inner peripheries of the bearing seats, and the outer peripheries of the bearing seats are fixedly connected to the bottom of the box body 1. The rotating shaft 20 is fixedly connected to the corresponding side plates 3 through the first connecting rod 21. The front and rear ends of the rotating shaft 20 are fixedly connected to one end of the first connecting rod 21, and the other ends of the first connecting rod 21 are fixedly connected to the bottom of the side plates 3. Worm gears 22 are fixedly installed on the rotating shaft 20. The rotating shaft 20 is coaxially arranged with the corresponding worm gear 22. A worm 23 is meshed with one side of the worm gear 22. The worm 23 is rotatably installed on the box body 1 through the bearing seats. The outer peripheries of the worm 23 are rotatably connected to the inner periphery of the bearing seats, and the outer peripheries of the bearing seats are fixedly connected to the bottom of the box body 1. The worm 23 is screwed, and the worm 23 rotates to drive the corresponding worm wheel 22 and the rotating shaft 20 to rotate. The rotating shaft 20 drives the side plate 3 to rotate along the axis of the corresponding rotating shaft 20 through the first connecting rod 21.

[0018] Specifically, as shown in the figure, one end of the worm 23 of this embodiment is fixedly mounted with a hand wheel 30, and the hand wheel 30 is coaxially arranged with the corresponding worm 23. It is more convenient and labor-saving to twist the worm 23 through the hand wheel 30.

[0019] Furthermore, as shown in the figure, the dust screens 2 described in this embodiment are fixedly mounted on rectangular frames 40. Two through-slots 41 are defined on the top of the housing 1, corresponding to the rectangular frames 40. The rectangular frames 40 engage with the corresponding through-slots 41. When the dust screens 2 need to be cleaned, they are pulled upward toward the rectangular frames 40, which then drive the corresponding dust screens 2 upward until the rectangular frames 40 and the corresponding dust screens 2 are completely removed through the through-slots 41. The cleaned dust screens 2 and rectangular frames 40 are then inserted into the through-slots 41, allowing the dust screens 2 to completely cover the opening of the housing 1.

[0020] Furthermore, as shown in the figure, the front and rear sides of the box body 1 described in this embodiment correspond to the rectangular frame 40, respectively, with two slide grooves 50. The rectangular frame 40 slides in contact with the corresponding slide grooves 50. The bottom of the box body 1 corresponds to the rectangular frame 40, with two grooves 51 inserted into the corresponding grooves 51. The upper and lower ends of the slide grooves 50 are connected to the through grooves 41 and the grooves 51, respectively. When the rectangular frame 40 and the dustproof net 2 are placed in the through grooves 41 and moved downward, the rectangular frame 40 slides downward along the corresponding slide grooves 50, making the rectangular frame 40 more stable when moving downward. When the rectangular frame 40 and the dustproof net 2 completely cover the opening of the box body 1, the lower side of the rectangular frame 40 is located in the grooves 51. The restraint of the grooves 51, the slide grooves 50, and the through grooves 41 make the rectangular frame 40 and the dustproof net 2 more stable.

[0021] Furthermore, as shown in the figure, baffles 60 are fixedly installed on the top of the rectangular frame 40 of this embodiment, and the baffles 60 extend out of the corresponding through slots 41. The baffles 60 facilitate grasping the rectangular frame 40 and taking the rectangular frame 40 out of the through slots 41.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
