Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-5 The utility model provides a technical solution: a sheet metal chassis with a dust filtering structure, including a sheet metal chassis body 1, a heat dissipation tube 2, a ventilation chute 3, a heat dissipation fan 4, a dustproof net 5, a limiting mechanism 6, a fixing block 7, a movable column 8, a protruding rod 9, a fixing column 10, a fixing groove 11, a cover plate 12, a water baffle 13, a connecting column 14, a fixing cap 15, a movable plate 16 and a fixing rod 17.

[0031] When using the sheet metal chassis with dust filtering structure, Figure 1 and Figure 2 As shown, the left and right ends of the sheet metal chassis body 1 are fixedly connected with heat dissipation tubes 2, and the outer side of the heat dissipation tube 2 is provided with ventilation chute 3 at equal intervals. Through the arrangement of the ventilation chute 3 and the water baffle 13 fixedly installed on the upper end of the cover plate 12, it can play a good waterproof effect in the daily use process while ensuring the smooth ventilation and heat dissipation, and prevent water from entering the sheet metal chassis body 1. In addition, a heat dissipation fan 4 is fixedly installed in the heat dissipation tube 2, and the heat dissipation fan 4 is staggered at the left and right ends of the sheet metal chassis body 1. The heat dissipation fan 4 is used to blow air into the sheet metal chassis body 1 to accelerate the air flow inside the sheet metal chassis body 1, so as to facilitate the rapid discharge of the heat inside the sheet metal chassis body 1. The overall heat dissipation efficiency is high, and a dustproof net 5 is provided on the side of the heat dissipation fan 4 close to the sheet metal chassis body 1. The dustproof net 5 is plugged and installed in the middle of the heat dissipation tube 2. Through the arrangement of the dustproof net 5, it is prevented that the external dust is blown into the sheet metal chassis body 1 during the blowing and heat dissipation process. The overall dustproof effect is good and the practicability is high.

[0032] When the metal sheet is processed, Figure 3 and Figure 4 As shown, put your hand between the cover plate 12 and the water baffle plate 13, rotate the fixing cap 15 threadedly connected to the outer surface of the connecting column 14, and rotate the fixing cap 15 and the movable plate 16, so that the fixing cap 15 drives the movable plate 16 to move upward, so that the movable plate 16 drives the cover plate 12 to move upward, and the fixing cap 15 is disengaged from the connecting column 14, thereby releasing the limit between the cover plate 12 and the sheet metal chassis body 1, making it easy to disassemble the cover plate 12 and the water baffle plate 13 from the sheet metal chassis body 1, and conveniently taking the processed products inside the sheet metal chassis body 1;

The movable column 8 is rotated, and at the same time, the movable column 8 drives the protruding rod 9 to move, so that the protruding rod 9 moves to the opening on the front side of the fixing groove 11, thereby loosening the limit between the dustproof net 5 and the heat dissipation tube 2, and then the dustproof net 5 is pulled upward, and the dustproof net 5 slides between the heat dissipation tube 2, and the dustproof net 5 drives the movable column 8 to be pulled out from the fixed column 10, and the protruding rod 9 is moved out from the opening on the front side of the fixing groove 11, so as to facilitate the disassembly and cleaning of the dustproof net 5 to prevent the dustproof net 5 from being blocked during long-term use, and it is very convenient to use.
