No further details are given. A rotating block 12 is rotatably connected to both ends of the surface of one side of the cabinet 1. An adjusting threaded rod 13 is rotatably installed on the side of the rotating block 12. An adjusting nut 14 is threadedly connected to the surface of the adjusting threaded rod 13. The position can be threadedly adjusted to ensure alignment with the surface of the control box 11 to avoid misalignment and interference, which is convenient for installation and use. One end surface of the adjusting nut 14 is slidably connected to the two end sides of the cabinet 1, and the other end surface of the adjusting nut 14 is provided with a hinge seat 15. The surface of the hinge seat 15 is hinged with a U-shaped connecting rod 16. The U-shaped connecting rod 16 is located on one side of the control box 11, and both ends of the U-shaped connecting rod 16 are rotatably installed with threaded shafts 17. One end of the threaded shaft 17 is fixedly connected to a winding rod 18. Both ends of the winding rod 18 are rotatably connected to the two end surfaces of the U-shaped connecting rod 16. The surface of the winding rod 18 is fixedly wrapped with a silicone protective film 19, which can be wrapped and shrunk for placement, or unfolded to cover the surface of the control box 11 for isolation and protection. The transparent structure will not affect the viewing of the buttons, which is conducive to operation and use. This can prevent pollution such as oil from penetrating into the interior, thereby improving safety of use. The silicone protective film 19 is located on one side of the control box 11.

[0029] See also Figure 2 and Figure 3 One end of the silicone protective film 19 is fixedly connected to the positioning strip 2, and both ends of the positioning strip 21 are provided with card joints 21. The other side surface of the U-shaped connecting rod 16 is provided with a positioning groove 22.

The cabinet door 29 is hinged by the hinge shaft 28, which can be connected from the outside for protection, double-layer protection, and is convenient for opening and closing.

[0031] When in use, the control box 11 can be fixedly installed on one side of the cabinet 1, and then the tightening screws 26 at both ends are turned, and the wedge block 25 is pushed by the tightening ball head 27 to ensure that the elastic plate 24 elastically presses the surface of one side of the control box 11, which can assist in positioning, ensure stability, and avoid movement and misalignment. Then the adjusting threaded rod 13 is rotated to move the adjusting nut 14 and the hinge seat 15 to ensure that the U-shaped connecting rod 16 is aligned with the surface of the control box 11, while avoiding obstruction and interference. Then the silicone protective film 19 can be unfolded and covered on the surface, and the positioning strip 2 is snapped into the positioning groove 22 for positioning. It can be stably unfolded for isolation and protection, and the transparent structure will not affect the viewing of the buttons, which is conducive to operation and use. This can prevent pollution such as oil from penetrating into the interior, improve safety of use, and at the same time, the U-shaped connecting rod 16 can be flipped around the hinge seat 15 to open, which will not affect cleaning and maintenance. It is stable, efficient, and highly adaptable.
