The dust-proof net fixing component 3 includes a fixed sliding rod 31 and a rotating rod 32. The middle of the rear end of the fixed sliding rod 31 is rotatably connected to the middle of the front end of the rotating rod 32 through a hinge, and the maximum cross-sectional dimensions of the fixed sliding rod 31 and the rotating rod 32 are equal. The inner wall of the square insertion hole 22 is movably connected to the outer wall of the fixed sliding rod 31. The connecting block 21 is inserted into the fixed sliding rod 31 through the square insertion hole 22, and the dust-proof net 2 is installed inside the installation groove 12, thereby installing the dust-proof net 2 on the outer wall of the computer housing 1.

[0025] The As Figure 4 figure shows, the present utility model provides a magnetic computer case dust-proof net. A notch is opened at the rear side of the bottom of the fixed sliding rod 31. Two connecting holes 311 are opened at the top of the inner wall of the notch. Two connecting rods 321 are provided on the front side of the rotating rod 32. A cavity 327 is opened at the front side of the top of the connecting rod 321. A spring 328 is fixedly connected to the bottom of the inner wall of the cavity 327. A fixed block 329 is fixedly connected to the top of the spring 328. The upper and lower sides of the fixed block 329 are both bevel edges. A jack 312 is opened at the rear side of the inner wall of the connecting hole 311. A square notch 322 is opened at the rear side of the top of the rotating rod 32. Two sliding grooves 324 are opened at the top of the square notch 322. A sliding rod 325 is movably connected to the inner wall of the sliding groove 324. Two limiting grooves 326 are opened on the front side of the rotating rod 32, and the rear side of the top of the limiting groove 326 is connected to the bottom of the sliding groove 324. The outer wall of the connecting rod 321 is movably connected to the inner wall of the limiting groove 326.

After the dust-proof net 2 is installed, rotate the rotating rod 32. Then slide the sliding plate 323. The sliding plate 323 drives the two sliding rods 325 to move along the sliding groove 324. The sliding rods 325 drive the connecting rod 321 to move along the limiting groove 326 and insert into the connecting hole 311. By the outer wall of the connecting hole 311 squeezing the hypotenuse of the fixed block 329, the fixed block 329 is pushed to the inner wall of the cavity 327 and the spring 328 is compressed. Then the spring 328 rebounds and inserts the fixed block 329 into the jack 312, thus fixing the rotating rod 32. By the rotating rod 32 blocking the connecting block 21, the dust-proof net 2 is prevented from falling off. The dust-proof net 2 can be removed by the reverse operation. Therefore, only by rotating the rotating rod 32 can the disassembly and assembly of the dust-proof net 2 be realized, which is convenient for the quick disassembly and assembly of the dust-proof net 2.
