Through the provided support assembly 9, the limit block 8 is more stable in the process of sliding at the vertical plate 10, thereby improving the stability of the limit block 8 when moving. An electric push rod 11 is rotatably provided between the two L-shaped plates 5. The telescopic rod of the electric push rod 11 is extended and retracted. Since the bottom and the end of the electric push rod 11 are rotatably connected with the two L-shaped plates 5, the telescopic end of the electric push rod 11 is extended and retracted, so that the L-shaped plate 5 is swung and adjusted with the support block 4 as the central axis, thereby cooperating with the rotatably connected support rod 6, and then the limit block 8 sliding at the two vertical plates 10 is moved in the opposite direction, so that the limit block 8 and the limit groove at the card block 2 are separated from each other, so that the bottom shell 1 is convenient to disassemble and remove, and the subsequent maintenance and use of the smart meter main body 903 is convenient to use;

[0026] The support assembly 9 includes two fixing plates 901, which are respectively fixedly mounted on the surface of the limit block 8. A spring 902 is sleeved on the surface of the limit block 8. By arranging the spring 902 on the surface of the two limit blocks 8, the movement of the limit block 8 can be stabilized.

[0027] One end of the spring 1 902 facing away from the fixed plate 901 is fixedly connected to one side of the vertical plate 10, and the other end is fixedly connected to the surface of the fixed plate 901, so that the spring 1 902 is installed and fixed to avoid instability at the spring 1 902;

[0028] The four corners of the surface of the mounting plate 3 are provided with mounting holes, which are convenient for fixing the mounting plate 3 at a suitable position with the help of bolt and nut groups. The surface of the upper shell 12 is respectively provided with a handle 905 and an observation window 906 for observing the indications, which is convenient for stretching and removing the upper shell 12. It is easy to use and convenient for the staff to observe the smart meter body 903 through the observation window 906 in time. Embodiment 2:

[0029] A mounting assembly 13 is provided on one side of the upper shell 12. The mounting assembly 13 includes two support plates 1301. The two support plates 1301 are symmetrically mounted on the surface of the bottom shell 1. A U-shaped pull rod 1302 is slidably mounted between the two support plates 1301. Two fixing blocks 1305 are symmetrically mounted on the surface of the upper shell 12. The insides of the two fixing blocks 1305 are provided with limiting holes matching the U-shaped pull rod 1302. The four corners of the surface of the upper shell 12 are engaged with the surface of the bottom shell 1 through limiting columns 1306. The U-shaped pull rod 1302 is stretched to separate from the limiting holes at the fixing blocks 1305, so that the upper shell 12 can be disassembled and removed easily. The four limiting columns 1306 inserted into the bottom shell 1 are provided to limit the upper shell 12.

[0030] Two springs 1304 are sleeved at the bottom of the U-shaped pull rod 1302, and a fixing ring 1303 is provided at the bottom of the U-shaped pull rod 1302. One end of the spring 1304 facing the fixing block 1305 is fixedly connected to the surface of the fixing ring 1303, and the other end is fixedly connected to the bottom of the support plate 1301. The spring 1304 provided at the U-shaped pull rod 1302 cooperates with the fixing ring 1303, so that the bottom of the U-shaped pull rod 1302 is plugged into the limiting hole at the fixing block 1305, which plays a role of reset support.

[0031] A plurality of heat dissipation slots 904 are provided on both sides of the bottom shell 1, and a dustproof net is provided on the surface of the heat dissipation slots 904. A wire groove for installing the wires of the smart meter body 903 is provided at the bottom of the bottom shell 1. A sealing sleeve is provided at the bottom of the wire groove, which is convenient for heat dissipation and dust prevention of the smart meter body 903, and is convenient for laying the wires of the smart meter body 903, and at the same time plays a sealing role;

[0032] A protective sleeve is provided in the middle of the U-shaped pull rod 1302. The protective sleeve is made of rubber material, which is convenient for protecting the U-shaped pull rod 1302 and having a certain anti-slip effect, making it convenient for staff to lift and move the U-shaped pull rod 1302.

[0033] When in use, first, by setting the mounting plate 3 and cooperating with the bolt and nut group, the mounting plate 3 is installed to the wall or other position to complete the installation of the bottom shell 1 and the internal smart meter body 903 and the upper shell 12. When the bottom shell 1 needs to be disassembled and removed, the telescopic rod of the electric push rod 11 is shortened by controlling the setting. Since the two ends of the electric push rod 11 are rotatably connected between the two L-shaped plates 5, the shortening of the telescopic rod of the electric push rod 11 makes the two L-shaped plates 5 swing synchronously with the support block 4 as the center. Since a rotatably connected support rod 6 is also provided at the top of the L-shaped plate 5, in cooperation with the rotating block 7, the two limit blocks 8 move synchronously in opposite directions, so that they are separated from the limit grooves at the card block 2, thereby facilitating the disassembly and removal of the bottom shell. Conversely, the extension of the telescopic rod of the electric push rod 11 is controlled to complete the installation of the bottom shell.

[0034] When the upper shell 12 needs to be disassembled, it is only necessary to stretch the U-shaped pull rod 1302 and lift the U-shaped pull rod 1302 upwards. At this time, the bottom of the U-shaped pull rod 1302 is separated from the limiting hole at the fixed block 1305. At this time, the spring 2 1304 is compressed, and then the upper shell 12 can be removed through the provided handle 905, and then the smart meter body 903 inside the bottom shell 1 can be inspected or maintained. After the maintenance is completed, repeat the above steps, stretch the U-shaped pull rod 1302 again, and limit the bottom shell 1 through the limiting column 1306. The U-shaped pull rod 1302 set by Panasonic can be installed on the upper shell 12 under the reset of the spring 2 1304.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
