The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0027] For the embodiments, please refer to Figures 1-4 , the present utility model provides a technical solution:

[0028] An electric energy meter control device includes a fixed seat 1. Wiring holes 101 are respectively opened on the top and bottom surfaces of the fixed seat 1. A first metal guide piece 1011 and a second metal guide piece 1012 are respectively arranged inside the wiring holes 101. Locking screws 102 are respectively movably embedded and installed at the top and bottom ends on the left side of the fixed seat 1. A battery slot 103 is opened on the rear surface of the fixed seat 1. A storage battery 1031 is snap-connected and arranged at the bottom end inside the battery slot 103. A slot cover 1032 is arranged outside the battery slot 103. A control panel 104 is fixedly installed on the left side of the fixed seat 1. A display screen 1041 and adjustment buttons 1042 are respectively arranged on the left side of the control panel 104. A transparent hard plastic is arranged on the outer surface of the display screen 1041 to facilitate the protection of the display screen 1041;

[0029] Among them, the outer surface of the first metal guide piece 1011 is fixedly connected to the inner wall of the wiring hole 101, and its cross-sectional shape is a U-shaped structure. The first metal guide piece 1011 is electrically connected to the control panel 104 through a wire. The front and rear surfaces of the second metal guide piece 1012 are attached to the front and rear ends inside the first metal guide piece 1011. The right end of the locking screw 102 sequentially passes through the left and right ends of the first metal guide piece 1011 and the second metal guide piece 1012, and is rotatably connected to the inner wall of the first metal guide piece 1011. The outer right end surface of the locking screw 102 is threadedly connected to the inner wall of the second metal guide piece 1012. The locking screw 102 plays a role in driving the second metal guide piece 1012 to move horizontally, so that the left side of the second metal guide piece 1012 gradually approaches the inner left end surface of the first metal guide piece 1011, facilitating the clamping of the power cord and ensuring the smoothness of the circuit. The outer side of the slot cover 1032 is slidably connected to the inner wall of the battery slot 103 through a chute. The type of the storage battery 1031 is a lithium-ion battery, which facilitates the protection of the storage battery 1031 and ensures the working state of the storage battery 1031, thus solving the problem that the device does not have an external power input and making it more convenient for the device to operate.

[0030] In this embodiment, please refer to Figure 1 、 Figure 2 and Figure 3 , a convenient installation mechanism 2 is provided on the right side of the fixed seat 1. The convenient installation mechanism 2 includes an installation groove 201 opened on the right side surface of the fixed seat 1. A fixed strip 202 is fixedly installed at the top end inside the installation groove 201, and a limiting block 203 is movably penetrated through the bottom end inside it. A compression spring 204 and a pull rod 205 are respectively fixedly installed at the bottom of the limiting block 203. A sliding rod 2041 is arranged inside the compression spring 204. The bottom end of the pull rod 205 movably penetrates through the bottom inner wall of the fixed seat 1 and is fixedly installed with an anti-detachment block 206. The anti-detachment block 206 plays a role in driving the pull rod 205 to move vertically, so that the pull rod 205 drives the limiting block 203 to move and makes the limiting block 203 contact the bottom of the strip at the installation position and form a snap connection, thus solving the problem that the bottom of the working base in the device lacks a convenient installation component and facilitating the installation by installers;

[0031] Among them, the right side surface of the fixing bar 202 and the right side surface of the fixing base 1 are in the same plane, which is convenient for the installation position of the fixing bar 202 to contact the top of the clamping bar. The bottom ends of the compression spring 204 and the sliding rod 2041 are fixedly connected to the inner bottom wall of the fixing base 1. The top end of the sliding rod 2041 movably penetrates through the bottom surface of the limiting block 203 and extends inward, and its length matches the height of the limiting block 203. The sliding fit between the sliding rod 2041 and the limiting block 203 ensures the smooth movement of the limiting block 203. The setting of the compression spring 204 facilitates the reset of the position of the limiting block 203. The anti-detachment block 206 is located below the fixing base 1 and is symmetrically distributed about the bottom central axis of the fixing base 1, which is convenient for moving the pull rod 205.

[0032] The working process of the present utility model: When using a power meter control device, first, move the slot cover 1032 through the chute and snap-install the battery 1031 at the inner bottom end of the battery slot 103. Under the condition of ensuring that the battery 1031 is electrically connected to the control panel 104 through a wire, make the slot cover 1032 fit tightly with the battery slot 103 through the chute. Secondly, install the device on the clamping bar at the required position. First, make the fixing bar 202 contact the top of the clamping bar, and then pull the anti-detachment block 206. The anti-detachment block 206 drives the pull rod 205 to move. As the pull rod 205 moves, the limiting block 203 moves vertically. Immediately, the compression spring 204 is squeezed and generates an elastic reaction force. The sliding rod 2041 and the limiting block 203 have a sliding fit, enabling the limiting block 203 to move smoothly until the top surface of the limiting block 203 is lower than the bottom surface of the clamping bar and ensuring that the fixing base 1 is parallel to the clamping bar. At this time, the anti-detachment block 206 can be released. Under the elastic reaction force, the compression spring 204 drives the limiting block 203 to move upward and closely contact the bottom of the clamping bar, thus completing the clamping connection between the fixing base 1 and the clamping bar, which is convenient for the installer to operate. Finally, first strip one end of the power cord and place it between the first metal guide piece 1011 and the second metal guide piece 1012, and then use a screwdriver to rotate the locking screw 102. Under the thread fit between the locking screw 102 and the second metal guide piece 1012, the second metal guide piece 1012 moves and pushes the power cord to gradually approach the inner left end surface of the first metal guide piece 1011 until the power cord is in close contact with the first metal guide piece 1011 and the second metal guide piece 1012. Then connect the other end of the power cord to the circuit of the power meter. Thus, the power meter can be controlled through the display screen 1041, the adjustment button 1042, and the corresponding control program.

[0033] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
