[0023] Example 2

[0024] like Figure 2As shown, in order to solve the problem of inconvenience in controlling the opening and closing of the door body 4, a dual-axis motor 6 is fixedly connected to the center of the top inner side of the door frame 2, and a threaded shaft 7 is fixedly connected to the end of the main shaft of the dual-axis motor 6, and the threaded shaft 7 is rotatably connected to the door frame 2, and the threaded shaft 7 passes through the slider 5, and the threaded shaft 7 is spirally connected to the slider 5, and the slider 5 is slidingly connected to the door frame 2. By controlling the dual-axis motor 6 to drive the threaded shaft 7 to be spirally connected to the slider 5, it is convenient to control the opening and closing of the door body 4 through the slider 5.

[0025] Example 3

[0026] like Figure 2 As shown, in order to solve the problem that it is inconvenient to automatically control the dual-axis motor 6 to stop after the door body 4 is opened or closed, a control switch 8 is provided at the top end of the outer side of the slider 5, and the control switch 8 is fixedly connected to the slider 5. The control switch 8 on one side is in contact with the door frame 2. After the door body 4 is opened or closed, the control switch 8 on one side is triggered by the slider 5, which facilitates the automatic control of the dual-axis motor 6 to stop.

[0027] Example 4

[0028] like Figure 2 、 Figure 3 and Figure 5 As shown, in order to solve the problem of poor sealing between the two door bodies 4 after the door bodies 4 are closed, a sealing gasket 12 is provided on the outside of the fixed plate 9, and the sealing gasket 12 is fixedly connected to the door body 4. The sealing gasket 12 is made of rubber. After the door bodies 4 are closed, the door bodies 4 on both sides are in contact with each other through the sealing gasket 12 made of rubber material, so that the sealing between the two door bodies 4 is better.

[0029] Example 5

[0030] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, in order to solve the problem that tools, parts and foreign objects cannot be prevented from falling into the door body slide groove at the bottom of the door frame 2 after the door body 4 is opened, an electric push rod 15 is fixedly connected to the bottom end of the inner side of the door frame 2, and a baffle 16 is fixedly connected to the top of the electric push rod 15, and the baffle 16 is slidably connected to the door frame 2.
