Slide into the limit groove 2, so that the cover plate 3 and the shell 1 are docked together, so that the fixing groove 4 on the cover plate 3 is aligned with the fixing groove 4 on the shell 1, and then slide the fixing block 6 into the fixing groove 4, and fix the embedding block 7 in the embedding groove 5 by screws, so that the fixing block 6 is fixed in the fixing groove 4, so that the cover plate 3 and the shell 1 are fixed together, and then when the twin-screw mechanical supercharger is overhauled, the screws on the embedding block 7 are unscrewed to take out the embedding block 7 and the fixing block 6, and the cover plate 3 can be removed, and the cover plate 3 can be quickly disassembled, and the disassembly work can be faster, which is convenient and fast for the maintenance of the twin-screw mechanical supercharger.

[0023] In one aspect of the present embodiment, the position of the card slot 12 is higher than the bottom of the limiting slot 2. Therefore, when the cover plate 3 needs to be slid into the bottom of the limiting slot 2, the cover plate 3 needs to be pressed down and carded into the card slot 12, so that the card block 11 slides downward between the opening slot 9 to squeeze the spring 10, and then the cover plate 3 and the housing 1 are fixed together by the fixing block 6 in the fixing slot 4. When fixed together, the elastic force of the spring 10 will act on the cover plate 3 so that the cover plate 3 has an upward force, which can make the fixing slot 4 push the fixing block 6 upward, so that So that the fixing block 6 fixes the cover plate 3 and the shell 1 more firmly, after the twin-screw mechanical supercharger is installed in the shell 1 and the cover plate 3 is fixed to the shell 1, the heat emitted by the twin-screw mechanical supercharger during operation will be dissipated from the heat dissipation groove 13, and the gauze 15 is fixed to the lower side position of the heat dissipation groove 13 in the installation groove 14, so that after the heat dissipation groove 13 dissipates the heat, air will also enter the shell 1 from the heat dissipation groove 13, and the gauze 15 can block dust in the air, which can effectively prevent dust from entering the shell 1 from the heat dissipation groove 13.

[0024] In one aspect of the present embodiment, through the provision of the buckle groove 16, when the shell needs to be transported and moved, the staff can buckle their hands into the buckle groove 16 to leverage the shell to lift it, so that the lifting and movement can be better leveraged. When the shell is placed, the rubber pad 18 fixedly connected in the groove 17 will contact the placement position. The rubber material has the function of increasing friction, so that the shell can be placed more stably and not easy to slide.

[0025] Working principle of the utility model: when the twin-screw supercharger housing is in use, after the twin-screw supercharger is installed inside the housing 1, the cover plate 3 is slid into the limiting groove 2. When the cover plate 3 needs to be slid into the bottom of the limiting groove 2, the cover plate 3 needs to be pressed down and inserted into the card slot 12, so that the card block 11 slides down between the opening slot 9 to squeeze the spring 10, and then the embedded block 7 is fixed in the embedded groove 5 by screws, so that the fixing block 6 is fixed in the fixing groove 4, so that the cover plate 3 is fixed to the housing 1. The cover plate 3 and the housing 1 are fixed together, and the elastic force of the spring 10 acts on the cover plate 3 so that the cover plate 3 has an upward force, so that the fixing groove 4 can press the fixing block 6 upward, so that the fixing block 6 can fix the cover plate 3 and the housing 1 more firmly. Later, when the twin-screw mechanical supercharger is overhauled, the screws on the embedding block 7 are unscrewed to take out the embedding block 7 and the fixing block 6, and the cover plate 3 can be disassembled. The cover plate 3 can be disassembled quickly, and the disassembly work can be faster, which is convenient and fast for the overhaul of the twin-screw mechanical supercharger.
