Please also refer to FIG. 10. When using the computer case 100, insert the first hook 32 of the cover plate 30 into the locking portion 181 provided on the second side plate 18, so that the cover plate 30 takes the first hook 32 as the axis. , turn toward the opening 28. The hook portion 344 of the second hook 34 first abuts against the inclined surface 662 of the fitting 60 , the cover plate 30 continues to rotate, and the hook portion 344 presses the inclined surface 662 , so that the mounting portion 68 of the fitting 60 moves along the first side plate 16 . The sliding groove 162 slides, and the elastic member 90 is stretched. During the sliding process of the fitting 60 , the hook portion 344 slides along the inclined surface 662 until the hook portion 344 enters the engaging portion 69 from the inclined surface 662 , and the hook portion 344 no longer resists the inclined surface 662 so that the sliding member 70 acts on the elastic member 90 . The bottom returns to its original position, the engaging part 69 engages with the second hook 34, the buckle part 76 engages with the third hook 36, the first hook 32 engages with the locking part 181, and the cover plate 30 is closed In the casing 10 , the resisting portion 72 resists the rotating member 59 at this moment.

When the cover plate 30 needs to be disassembled from the computer case 100, the operating member 52 is pulled, the operating member 52 drives the rotating shaft 54 to rotate, and then drives the rotating member 59 fixed on one end of the rotating shaft 54 to rotate, the torsion spring 56 elastically deforms, and the rotating member 59 rotates. The abutting part 72 of the sliding part 70 is pressed against, so that the sliding part 70 slides relative to the casing 10, and the sliding part 70 drives the matching part 60 to slide together, so that the buckle part 76 and the engaging part 69 are separated from the third hook 36 and the third hook 36 respectively. Two hooks 34, at this time the elastic member 90 is stretched. At this time, continue to pull the operating member 52 to drive the cover plate 30 to rotate with the first hook 32 as the axial direction away from the opening 28 , so that the cover plate 30 is detached from the first side plate 16 . Under the action of the elastic member 90 , the sliding member 70 drives the matching member 60 to return to its original position. The cover 30 can be disassembled by disengaging the first hook 32 from the locking portion 181 , which is more convenient. Release the operating member 52, and under the action of the torsion spring 56, the operating member 52 returns to its original shape.

It can be understood that the number of the second hook 34 and the matching member 60 can also be one or more, and at this time, the number of the sliding groove 162 and the positioning portion 74 are set correspondingly. The third hook 36 and the buckle portion 76 can be omitted, and the operating member 52 , the torsion spring 56 and the snap ring 58 can be omitted. At this time, the rotating member 59 can be pulled to rotate. The first mounting plate 12 and the second mounting plate 14 can be omitted. The fixing portion 64 can also be a through hole opened in the main body portion 62 . In this case, the positioning portion 74 corresponds to a protrusion protruding from the sliding member 70 to cooperate with the fixing portion 64 .

In addition, those skilled in the art can also make other changes within the spirit of the present invention. Of course, these changes made according to the spirit of the present invention should be included in the scope of protection claimed by the present invention.
