[0002] A server is a type of computer that has fast computing power, stable operation, and powerful data reading and writing capabilities. When a server is installed, it is mainly installed in a corresponding chassis. When the server is running in the chassis, it will generate heat. In order to ensure the operation of the server and other electronic equipment in the server chassis, most chassis will choose to open heat dissipation holes on the side walls of the chassis to ensure air circulation in the server chassis.

[0003] In the prior art, in order to prevent dust from entering the chassis and damaging the internal servers and electronic devices, dust screens are usually installed on the heat dissipation holes of the chassis. However, after the dust screen is used on the chassis for a period of time, a lot of dust is absorbed by the dust screen, which is easy to cause clogging of the dust screen, resulting in reduced air circulation inside and outside the chassis, and even causing the air inside and outside the chassis to be unable to circulate, so the dust screen needs to be replaced or cleaned.

[0004] In response to the above problems, the invention with patent publication number CN115657805A discloses a server chassis, which includes a chassis body, a dustproof mechanism is arranged on one side of the chassis body, the dustproof mechanism includes a first frame, a second frame, a dustproof net and a locking mechanism, the first frame and the second frame are fixedly connected to the chassis body, the dustproof net is located between the first frame and the second frame, the locking mechanism is arranged on the inner side of the first frame or the second frame, and is located at the end of the first frame or the second frame, locking mechanisms are respectively arranged on both sides of the dustproof net, and the locking mechanism is locked and connected to the dustproof net.

[0005] The invention sets a dustproof mechanism on one side of the box, places the dustproof net between the two frames, fixes the dustproof net through the locking mechanism, and can also be removed through the locking mechanism when it needs to be cleaned or replaced, solving the problem that the dustproof net in the existing dustproof equipment is not easy to remove and replace. However, when replacing, personnel still need to regularly replace and clean on site, which is a cumbersome operation. Utility Model Content

[0031] Working method:

[0032] During dust prevention, the rotating shaft 23 and the servo motor 21 support the conversion frame 24, which then supports the dustproof net 25 to prevent it from falling. One of the dustproof nets 25 covers the heat dissipation area and contacts and fits with the outer side of the chassis 1 to prevent external dust from entering the chassis 1 through the heat dissipation holes. The other dustproof nets 25 are located outside the heat dissipation area. A timed rotation is set on the controller 22.
