[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a light shield for an electric meter, comprising a top plate 1. A groove 2 is provided at the top right end of the top plate 1. The groove 2 provides a track and space for the sliding of subsequent components, allowing the entire light shield structure to achieve certain adjustment functions to meet different usage needs. This provides a foundation for the flexibility and adjustability of the entire device. The groove 2 is connected to a fixed plate 4 via a sliding assembly 3. A side baffle 5 is rotatably connected to the bottom right end of the fixed plate 4. The rotatable connection of the side baffle 5 allows it to be flexibly opened or closed. When the electric meter needs to be installed, repaired, or read, the side baffle 5 can be rotated open; after the operation is completed, it can be rotated closed. This effectively blocks ambient light, preventing interference with the electric meter, improving the accuracy and stability of the electric meter reading, and also providing some protection for the instrument, preventing dust and debris from entering. Objects entering from the side can affect the normal operation of the instrument. Fixed plate 4 is connected to the bottom of top plate 1 through limiting component 6. The presence of limiting component 6 ensures the positional accuracy and stability of fixed plate 4 during movement and use, preventing unnecessary displacement of fixed plate 4 and ensuring the robustness and reliability of the entire light shield structure, enabling it to stably perform its light shielding and protective functions. Fixed plate 7 is fixedly connected to the bottom left end of top plate 1, and side baffle 8 is rotatably connected to the bottom left end of fixed plate 7. Side baffle 8 and side baffle 5 work together to form side protection for the power metering instrument. When the two are rotated and closed, they can better block light from different directions and external interference, creating a relatively closed and well-lit working environment for the power metering instrument. At the same time, the overall structure is foldable, allowing the light shield to be folded into a smaller shape when not in use, making it easy to carry and store. It can also be quickly fixed in shape when unfolded for use.

[0027] Reference Figure 1 , Figure 3 and Figure 5The sliding assembly 3 includes a slide rod 301 and a return spring 303. The slide rod 301 is fixedly connected to the left and right sides of the inner wall of the slide groove 2. A slider 302 is slidably connected to the outside of the slide rod 301. The slide rod 301 provides a precise sliding track and support for the slider 302, ensuring that the slider 302 slides smoothly in a straight line during movement. This ensures the stability and accuracy of the entire structure during adjustment and avoids affecting the performance of the sunshade due to irregular movement of components. The slider 302 is fixedly connected to the top left end of the fixed plate 4. The sliding of the slider 302 on the slide rod 301 can drive the fixed plate 4 to adjust its position, so that the shading range and angle of the sunshade can be adjusted according to the power supply. The light shield is flexibly adjusted according to the actual situation of the metering instrument, improving its applicability and versatility, and meeting the usage requirements of power metering instruments of different specifications and installation positions. The left end of the return spring 303 is fixedly connected to the right side of the slider 302, and the right end of the return spring 303 is fixedly connected to the right side of the inner wall of the slide groove 2. The return spring 303 surrounds the outside of the slide rod 301. When the operator applies an external force to the fixed plate 4, causing the slider 302 to slide on the slide rod 301, the return spring 303 will be compressed or stretched, storing elastic potential energy. When the external force disappears, the return spring 303 uses the stored elastic potential energy to return the slider 302 and the fixed plate 4 to the initial position, realizing automatic clamping. The fixed function facilitates operation. The slider 302 is slidably connected to the inner wall of the slide groove 2. The top of the slider 302 is higher than the top of the top plate 1. This design makes it convenient for operators to manually operate the slider 302, making it easy to apply force and improving the convenience and operability of operation. The bottom of the side baffle 1 5 and the side baffle 2 8 are both fixedly connected to a handle 11. The handle 11 makes it easy for operators to rotate the side baffle 1 5 and the side baffle 2 8. The limiting component 6 includes a T-shaped groove 601, which is opened on the front and rear sides of the bottom right end of the top plate 1. The inner wall of the T-shaped groove 601 is slidably connected to a limiting block 602, which is fixedly connected to the top of the fixed plate 1 4. The front and rear ends of the T-shaped groove 601 and the limiting block 602 cooperate to ensure that the fixing plate 4 can slide in a certain range in the horizontal direction while limiting it in the vertical direction. This prevents the fixing plate 4 from moving up and down during use, enhances the stability and safety of the structure, and avoids structural deformation or damage to the sunshade due to vertical displacement. This ensures the sunshade's shading and protection effects. The bottom of the fixing plate 4 and the fixing plate 7 are both provided with a slot 9 near one end. The slot 9 is provided with a magnetic strip 10. The magnetic strip 10 allows the side baffle 5 and the side baffle 8 to be in a stable closed state when not in use, making them easy to store.

[0028] Working principle: When it is necessary to repair or read the power meter, the operator can turn the handle 11 to open the side baffle 5 and the side baffle 8. The slide groove 2 at the top right end of the top plate 1 provides a track for the sliding component 3. The operator can manually push the slider 302 to slide on the slide rod 301, which will drive the fixed plate 4 to adjust its position. At the same time, the T-shaped groove 601 of the limiting component 6 and the limiting block 602 cooperate to ensure that the fixed plate 4 slides stably and does not move up and down. This allows for flexible adjustment of the size of the light shield to adapt to different specifications of power meter. During this process, the reset spring 303 is compressed or stretched to store elastic potential energy. After the operation is completed and the external force disappears, it will automatically reset and clamp and fix. After use, turn the side baffle 5 and the side baffle 8 to close. When closed, the magnetic strip 10 at the bottom of the side baffle 5 and the side baffle 8 will be attracted into the slot 9 of the fixed plate 4 and the fixed plate 7 to ensure a tight closure, which is convenient for carrying and storing when not in use.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
