[0031] Refer to Figures 1-5 ,

[0032] Embodiment:

[0033] The structure for the electromagnetic shielding housing of a switch includes an outer housing 1. At the four corners of the lower surface of the outer housing 1, there is a fixedly connected roller fixing block 3. Inside the roller fixing block 3, there is a rotatably connected roller 14. The left and right surfaces of the roller 14 penetrate into the inside of the roller fixing block 3 and are rotatably provided with a rotating shaft 15. On the outer surface of the rotating shaft 15, there is a rubber pad 16. On the outer circumferential surface of the rubber pad 16, there is a fixedly connected blocking block 18. On the side of the circumferential surface of the blocking block 18, there is a fixedly connected fixed cross block 17. At the four corners of the lower surface of the electromagnetic shielding outer housing of the switch, a roller structure is fixedly connected. In this roller structure, a structure for fixing the roller is designed. On the outer surface of the rotating shaft of the roller, a rubber pad is connected. At the same time, on the outside of the rubber pad, there is a fixed cross block that can be connected to the roller fixing block. After the operator moves the device to the working area, the fixing structure can be installed on the surface of the rotating shaft. Through the frictional force generated between the rubber pad and the rotating shaft, the rotating shaft can be fixed to stop its rotation, thereby fixing the movement of the overall device, improving the convenience of the device, and at the same time reducing more manual output.

[0034] On the upper surface of the outer housing 1, there is a fixedly connected upper anti-collision cover 5. A layer of anti-collision cover is installed on the upper surface of the outer housing to prevent the device from being damaged due to heavy objects placed on the upper surface of the device, increasing the safety of the device and at the same time improving the reliability of the device operation.

[0035] The front surface of the outer housing 1 is provided with a front windshield glass plate 4. A handle 2 is fixedly connected to the front surface of the front windshield glass plate 4 near the right edge. The front windshield glass plate is installed on the front surface of the outer housing, which not only protects the safe operation of the internal equipment but also facilitates the operator to timely observe the operation conditions inside the device. In case of an accident, the operator can handle it in time, improving the operation stability.

[0036] At the center position of the upper part of the rear surface of the outer housing 1, a fan fixing block 6 is fixedly connected. A fan 7 is arranged through the center position of the fan fixing block 6. Connecting the fan fixedly at the center position of the upper part of the rear surface of the outer housing facilitates the cooling treatment of the whole equipment inside, preventing the internal equipment from having an accident due to too long operation time and too high temperature, and increasing the operation reliability of the equipment.

[0037] An air outlet net 8 is arranged at the lower part of the rear surface of the outer housing 1. Arranging the air outlet net at the lower part of the fan structure facilitates the discharge of the internal hot gas from the equipment, accelerating the internal air circulation and improving the stability of the equipment.

[0038] An electromagnetic shielding layer 9 is fixedly connected to the inner surface of the outer housing 1. A placement plate 12 is fixedly connected horizontally inside the outer housing 1. Fixing the electromagnetic shielding layer on the inner surface of the outer housing can prevent the electromagnetic radiation emitted by the internal equipment from affecting the external operator, improving the safety of equipment use. At the same time, installing the placement plate inside the outer housing for placing equipment increases the convenience of the equipment.

[0039] The fan 7 penetrates through to the inner rear surface of the outer housing 1 and is fixedly connected with a fan front cover 10. A fan blade housing 11 is fixedly connected to the outer circumferential surface of the fan front cover 10. Installing a front cover inside the outer housing where the fan is located is used to block the sundries blown into the equipment by the fan, preventing the sundries from entering the equipment and improving the operation reliability.

[0040] A lighting lamp 13 is fixedly connected to the center position of the upper surface inside the outer housing 1. Installing the lighting lamp inside the outer housing improves the internal visibility and the convenience of equipment use.

[0041] The implementation principle of the structural embodiment of the electromagnetic shielding housing for the switch of the present application is as follows: In the present application, roller structures are fixedly connected to the four corners of the lower surface of the electromagnetic shielding outer housing of the switch. A structure for fixing the rollers is designed in the roller structure. A rubber pad is connected to the outer surface of the rotating shaft of the roller. At the same time, a fixed cross block that can be connected to the roller fixing block is arranged outside the rubber pad. After the operator moves the equipment to the working area, the fixing structure can be installed on the surface of the rotating shaft. Through the friction force generated between the rubber pad and the rotating shaft, the rotating shaft can be fixed to stop rotating, thereby fixing the movement of the whole equipment, improving the convenience of the equipment and reducing more human effort output.

[0042] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
