The dust-proof mechanism 3 further includes a first clamping head 301, the first clamping head 301 is fixedly connected to the connection port 2, the second clamping head 303 is movably connected to a position below the first clamping head 301. The dust-proof mechanism 3 further includes a third clamping head 307 and a fourth clamping head 309, the third clamping head 307 is fixedly connected to the left and right sides of the storage bin 306, the fourth clamping head 309 is fixedly connected to the left and right sides of the cover plate 308, the fourth clamping head 309 is movably connected to a position below the third clamping head 307. The dust-proof cover 302 is pressed towards the connection port 2, so that the first clamping head 301 is clamped into the position below the second clamping head 303, and the dust-proof cover 302 is installed on the connection port 2. The cover plate 308 moves downward through the fourth clamping head 309 to a position below the third clamping head 307 of the storage bin 306, so that the cover plate 308 is fixedly connected to the storage bin 306, thus facilitating the installation of the cover plate 308 on the storage bin 306.

[0021] As Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown in the figure, the storage bin 306 is fixedly connected to the side position of the dust-proof cover 302. A cover plate 308 is movably installed on the storage bin 306. The connecting plate 311 is fixedly connected to the upper position inside the dust-proof cover 302. The pressing frame 312 is movably installed inside the dust-proof cover 302 and is located below the connecting plate 311.

Move the movable rod 313 upward, so that the pressing frame 312 moves upward and the spring 314 is compressed. Pull the dust-proof net 310 out to the side. The dust-proof net 310 inside the storage bin 306 synchronously moves into the dust-proof cover 302 through the movable groove 305. When the old dust-proof net 310 inside the dust-proof cover 302 is removed and the new dust-proof net 310 moves into the dust-proof cover 302, release the movable rod 313, so that the pressing frame 312 moves downward to fix the dust-proof net 310, thus facilitating the replacement of the dust-proof net 310.

[0022] It should be noted that the present utility model is a dust-proof upper cover for a chassis. The dust-proof cover 302 is squeezed towards the connection port 2, so that the first clamping head 301 is clamped under the second clamping head 303. The first clamping head 301 and the second clamping head 303 are mutually squeezed, thereby installing the dust-proof cover 302 onto the connection port 2. When disassembly is required, the dust-proof cover 302 is forcefully pulled out from the connection port 2, thereby disassembling the dust-proof cover 302. The cover plate 308 moves downward through the fourth clamping head 309 to a position below the third clamping head 307 of the storage bin 306, so that the cover plate 308 is fixedly connected to the storage bin 306, thereby facilitating the installation of the cover plate 308 on the storage bin 306. Similarly, by forcefully pulling out the cover plate 308, the cover plate 308 is facilitated to be disassembled. The movable rod 313 is moved upward, so that the pressing frame 312 is moved upward, so that the pressing frame 312 moves towards the connecting plate 311, so that the spring 314 is compressed. The dust-proof net 310 is pulled out to the side, so that the dust-proof net 310 is moved out of the movable groove 305 on one side of the dust-proof cover 302 to an external position. The dust-proof net 310 in the storage bin 306 synchronously moves into the dust-proof cover 302 through the movable groove 305. When the old dust-proof net 310 in the dust-proof cover 302 is moved out and the new dust-proof net 310 is moved into the dust-proof cover 302, the movable rod 313 is released, so that the compressed spring 314 resumes expansion, so that the pressing frame 312 moves downward to fix the dust-proof net 310. Then, after the old dust-proof net 310 is cut off, the dust-proof mechanism 3 can be used for a longer time, and the dust-proof net 310 is convenient to replace.
