[0024] Example:

[0025] Reference Figure 1-Figure 4 A guide rail type electric energy meter comprises a shell 1 with a guide rail groove 101 on the back. The shell 1 can be slid and installed on the guide rail by means of the guide rail groove 101, and an electric energy component is arranged in the shell 1, and the electric energy component usually includes the following main parts: Dial: numbers or pointers showing the amount of electric energy used, usually in kilowatt-hours. Metering device: measures current and voltage to calculate the amount of electric energy used. Casing: protects the internal components of the electric energy meter from the influence of the external environment. Terminal block: used to connect the electric energy meter to the power line. Lead sealing screw: used to seal the casing of the electric energy meter to prevent unauthorized interference. A wiring hole is opened at the bottom of the shell 1 for connecting the wires.

[0026] Also, please refer to Figure 2 and Figure 3As shown in, a cavity 2 is also opened in the shell 1, and the cavity 2 is connected to the guide rail groove 101, and a bottom plate 201 is fixedly connected in the cavity 2, and a guide rod 6 is fixedly connected on the bottom plate 201, and a top plate 5 is fixedly installed at the end of the guide rod 6, so that the guide rod 6 can be limited. At the same time, a rotating shaft 3 is also fixedly connected in the cavity 2, and a rotatable limiting plate 4 is also installed on the rotating shaft 3, and a contact plate 401 is also arranged at the end of the limiting plate 4, and the material of the contact plate 401 is rubber or silicone, and the contact end of the contact plate 401 can be against the outer wall of the guide rail, and the material of the contact plate 401 is rubber or silicone, which can increase the friction with the outer wall of the guide rail, and improve the limiting effect of the contact plate 401.

[0027] In order to better improve the limiting effect of the limiting plate 4, please refer to Figure 3 As shown in the figure, a horizontal plate is also slidably connected to the guide rod 6, and two groups of horizontal plates are provided, namely a pressure reducing horizontal plate 601 and a pressure increasing horizontal plate 602, and a slide groove 102 is also opened on the side wall of the shell 1, and the horizontal plate extends into the slide groove 102, and the horizontal plate can slide in the slide groove 102, and can be pushed or pressed by hand.

[0028] Here, in order to better limit the horizontal plate, a spring 402 is fixedly connected to the bottom plate 201, and the end of the spring 402 is fixedly connected to the bottom of the boosting horizontal plate 602, and the decompression horizontal plate 601 and the boosting horizontal plate 602 are fixedly connected by a connecting plate with a gap between them, and then the limiting plate 4 is extended into the gap, please refer to Figure 4 As shown in FIG. 4 , the limiting plate 401 is limited by the spring 402 , so that the contact end of the contact plate 401 abuts against the outer wall of the guide rail, thereby enabling the contact plate 401 to maintain a stable state on the guide rail.
