This step has a cleaning effect on dust and dirt that may accumulate in the computer slot 22, thereby reducing the damage of dust to the computer.

[0032] like Figure 1 , Figure 4As shown, the interior of the display cabinet body 1 is fixed with a colored light 72; the interior of the display cabinet body 1 is fixed with a partition plate 73; the interior of the partition plate 73 is fixed with a rubber pad 71; the middle of the display cabinet body 1 is rotatably connected with a rotating shaft 75; the rotating shaft 75 is rotatably connected with a glass door panel 74; when working, the partition plate 73 will separate the space of the display cabinet body 1, and the colored light 72 will illuminate it. The glass door panel 74 is rotated by the rotating shaft 75 rotatably connected to the display cabinet body 1 to achieve the opening and closing effect. A rubber pad 71 is placed at the bottom of each compartment, and the exhibits are placed on the rubber pad 71. This step can attract customers by using lights to attract the attention of customers. At the same time, due to the wide variety of computer hardware, the compartments are used to classify them, so that the display of exhibits is more ornamental, the exhibits are protected to a certain extent, and the viewing is not affected. It can also prevent dust from entering the display cabinet body 1, polluting and damaging the exhibits, increasing the friction between the exhibits and the display cabinet body 1, and making the exhibits more stable when placed in the compartments, thereby strengthening the protection of the exhibits. The working principle is that the knob 100 is rotated to drive the transmission shaft 18 and the block 19 to rotate, and then drive the gear 17 and other parts to rotate, so that the rack 14 is translated, and then the slider 12 and the connecting plate 13 fixed to the rack 14 are translated inside the slide frame 11, and multiple groups of sliders 12 can be moved away to place exhibits. When the knob 100 is stopped, the first spring 15 compressed by the movement of the slider 12 provides a reaction force to clamp the exhibit. At the same time, the deformation of the second spring 103 caused by the rotation of the transmission shaft 18 restores the second spring 103 to its original state when released, so that the gear 17 and the reverse gear 102 rotate, driving the slider 12 and the fixing plate 105 to further fix the exhibit. When the exhibit needs to be taken out, it only needs to turn the fixing plate 105 to conveniently take out the exhibit.

The flexible cloth 51 is deformed due to the squeezing of the exhibits. The fixing block 53 is used to fix the flexible cloth 51 to reduce the risk of falling off during use. This step reduces the possibility of accidental falling off of the exhibits when clamping the exhibits with irregular appearances, and is easy to replace when the flexible cloth 51 is damaged or loses its characteristics. The sliding column 62 slides in the second sliding groove 61, thereby driving the cleaning plate 63 to move back and forth in the computer slot 22. This step has a cleaning effect on the dust and dirt that may accumulate in the computer slot 22, reducing the damage to the computer by dust. The partition plate 73 will The space of the cabinet body 1 is separated, and the colored lights 72 will illuminate it. The glass door panel 74 is rotated by the rotating shaft 75 rotatably connected to the display cabinet body 1 to achieve the opening and closing effect. Rubber pads 71 ​​are placed at the bottom of each compartment, and exhibits are placed on the rubber pads 71. This step can attract customers by using lights to attract customers' attention. At the same time, due to the wide variety of computer hardware, the compartments are used to classify them, making the display of exhibits more ornamental, and the exhibits are protected to a certain extent without affecting the viewing. It can also prevent dust from entering the display cabinet body 1, polluting and damaging the exhibits, increasing the friction between the exhibits and the display cabinet body 1, making the exhibits more stable when placed in the compartments, and strengthening the protection of the exhibits. ;
