[0028] Embodiment

[0029] This embodiment provides a nameplate installation structure for an electric energy meter. The electric energy meter includes a housing and a connection cover 2 covering the upper part of the housing. A display window 1 is opened in the connection cover 2. A transparent display board 3 for displaying nameplate information is installed at the display window 1. A clamping structure 4 is provided between the display board 3 and the nameplate. The clamping structure 4 includes a clamping portion 41 provided on one side of the display board 3 or the nameplate and a clamping groove 42 provided on the other side for the clamping portion 41 to be inserted into. An extension wing 5 capable of quickly taking it out from the display board 3 is provided on the nameplate.

[0030] The above specific improvement is as follows: As Figures 1-4 shown, a display window 1 is opened on the connection cover 2, and a transparent display board 3 is pasted with adhesive at the display window 1. The nameplate is installed on the display board 3 to display the information of the electric energy meter. Compared with the prior art, 4 clamping portions 41 and 4 clamping grooves 42 are respectively provided at the display board 3 and the nameplate. During installation, the clamping portion 41 is inserted into the clamping groove 42 to complete the installation. The originally required cutting part on the nameplate is bent into the extension wing 5, so that no additional materials need to be added, and waste utilization can be better realized. When the nameplate needs to be replaced, hold the extension wing 5 with both hands, and the clamping portion 41 can be disengaged from the clamping groove 42 externally. When the extension wing 5 is not needed, the extension wing 5 can be bent to both sides, which will not interfere with the subsequent installation of the liquid crystal display screen. This connection method can install the nameplate more quickly and conveniently, thus effectively improving work efficiency.

[0031] Based on the above embodiment: The clamping portion 41 is provided on one side of the nameplate, the clamping groove 42 is provided on one side of the display board 3. A plurality of positioning blocks 6 are provided on the side of the display board 3. The clamping groove 42 is opened in the positioning block 6. A guiding inclined surface 61 for guiding it to be inserted into the clamping groove 42 is provided on the side of the clamping portion 41 opposite to the clamping groove 42. Avoidance grooves 7 capable of avoiding the positioning blocks 6 are provided on both sides of the clamping portion 41.

[0032] The above specific improvement is as follows: As Figure 4 and Figure 9 shown, when installing the nameplate, first insert the clamping portion 41 on one side of the nameplate into the clamping groove 42, then press the nameplate into an arch shape, and install the clamping portion 41 on the other side into the clamping groove 42 as well. The setting of the guiding inclined surface 61 on the clamping portion 41 makes the contact area where the clamping portion 41 is inserted into the clamping groove 42 smaller, so that the clamping portion 41 can be quickly inserted into the clamping groove 42. Avoidance grooves 7 for avoiding the positioning blocks are provided on both sides of the clamping portion 41. Through the setting of the avoidance grooves 7, the two side positions of the positioning block 6 can be inserted into the avoidance grooves 7, making the nameplate fixed more stably.

[0033] On the basis of the above embodiment: the side of the positioning block 6 is provided with an abutment column 8 for supporting the clamping portion 41 when the clamping portion 41 is inserted into the positioning block 6, and the abutment column 8 includes a guide end 81 and an abutment end 82, and the guide end 81 is located on the side close to the positioning block 6.

[0034] The above specific improvements are: Figures 4-8 As shown, an abutment column 8 is provided on the side of the positioning block 6, and the abutment column 8 is divided into an abutment end 82 and a guide end 81. The guide end 81 is a guiding slope. When the clamping part 41 of the nameplate is inserted into the plug-in slot, the clamping part 41 will first contact the guiding slope, and reach the abutment end 82 through the guidance of the guiding slope, so that the lower end surface of the clamping part 41 will contact the upper end surface of the abutment end 82, thereby positioning the position of the nameplate.

[0035] On the basis of the above embodiment: the inner wall of the connection cover 2 is provided with a positioning component 9 which is in contact with the display panel 3 or the positioning block 6 .

[0036] On the basis of the above embodiment: the positioning assembly 9 includes a first positioning column 91 abutting against the side of the positioning block 6 and a second positioning column 92 abutting against the side of the display panel 3 .

[0037] The above specific improvements are: Figure 1 and Figure 3 As shown, the positioning assembly 9 includes a first positioning column 91 and a second positioning column 92. The first positioning column 91 and the second positioning column 92 are used to quickly fix the position of the display panel 3. During installation, the first positioning column 91 can quickly determine the lateral position of the display panel 3, while the second positioning column 92 can quickly determine the longitudinal position of the display panel 3. Therefore, through the coordinated setting of the first positioning column 91 and the second positioning column 92, the position of the display panel 3 can be quickly determined, so that the display panel 3 can be quickly installed, thereby improving the processing efficiency.

[0038] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
