Description

Technical Field

[0002] A switch is a key network device in a computer network, used to connect multiple computers, servers or other network devices, and to achieve communication between them by forwarding data packets. In order to speed up heat dissipation during use, a heat dissipation hole is set on the shell of the switch. In order to prevent external dust from entering the switch through the heat dissipation hole, a dustproof structure is installed at the heat dissipation hole. The existing dustproof structure of the heat dissipation hole of the switch is usually fixed to the switch by multiple bolts. This installation requires the staff to use professional tools to screw multiple bolts to complete, thereby reducing the efficiency of the installation and disassembly maintenance of the dustproof structure; secondly, the existing dustproof structure of the heat dissipation hole of the switch usually needs to filter the air entering the switch through a filter, but the filter will adhere to a lot of dust after long-term use, and the filter is prone to clogging, thereby reducing the air circulation and reducing the heat dissipation effect inside the switch.
