[0058] The present application provides a device for facilitating replacement of an electric energy meter by providing a latch 4 on a side of the electric energy meter 1 away from a display end, first engaging the latch 4 with a latch sleeve 31, and then utilizing a first groove 35 and a second groove 36 provided on a fixed back plate 3 of the electric energy meter to respectively engage with a first buckle 12 and a second buckle 13 on a side of the electric energy meter 1 away from a display end, thereby completing the fixing work of the fixed back plate 3 of the electric energy meter and the electric energy meter 1, and then providing a fixing hook 5 in the electric energy meter cover box 2, utilizing a hanging ring provided on the fixed back plate 3 of the electric energy meter to hang it on the fixing hook 5, and utilizing a fixing ring 53 to fix it, thereby completing the fixing work of the electric energy meter 1 to the electric energy meter cover box 2, so that the electric energy meter 1 and the electric energy meter cover box 2 fit tightly together.

[0059] The device provided by the present application is convenient for replacing an electric energy meter, which solves the problem that on-site installation is greatly affected by business skills and environment. No electric tools are required. When the wall surface where the electric energy meter is installed on site is uneven, the wall angle is not perpendicular to the ground or the ground is uneven, the installer does not need to fix the electric energy meter while drilling and tightening the screws laboriously, and work on the ladder for a long time, which ensures the work safety of the installer and reduces the work difficulty of the installer. The device provided by the present application improves the efficiency of replacing the electric energy meter, does not require repeated installation and removal of screws, and effectively avoids the occurrence of screws falling off, loss, and damage to the fixing part of the electric energy meter cover box or damage to the screw nut due to repeated fixing and removal of screws, making the screws unable to be fixed and removed. The device provided by the present application reduces the time for frequent replacement of electricity meters and reduces the workload of power supply companies. With the development of the rural economy, electricity consumption has changed greatly and the load has continued to increase, making the actual capacity far exceed the capacity of the power supply equipment. The over-capacity usage can easily cause the electricity meter to malfunction or burn out. In addition, there are some short-circuit problems of single-phase electronic electricity meters, short-circuit problems of three-phase electricity meters, safety problems when wiring electricity meters, etc., which increase the probability of replacing electricity meters. Reducing the time for replacing meters can greatly reduce the workload of power supply sites. The device provided by the present application can effectively avoid the phenomenon of causing irregular operation results; currently, each electric energy meter is installed in the meter box with at least 3 screws, and 1 to 2 of the 3 screws of many electric energy meters are not screwed into place or are twisted crooked, such as only fixing 1 screw on the meter head and 1 screw in the meter foot, or even only fixing 1 screw on the meter head so that the electric energy meter is fixed by only 1 screw. Due to the long-term uneven force or concentrated force of the above-mentioned method of installing the electric energy meter, it is easy to cause the electric energy meter cover box and the electric energy meter to deform, reducing the service life of the electric energy meter and increasing the replacement frequency of the electric energy meter. The device provided by the present application can avoid using screws to fix the electric energy meter in the electric energy meter cover box, and make the connection between the electric energy meter and the electric energy meter cover box more firmly, effectively avoiding the phenomenon of increased replacement frequency of the electric energy meter due to deformation of the electric energy meter cover box and the electric energy meter. The device provided by the present application increases the stress area of ​​the running electric energy meter; due to the uneven wall surface where the electric energy meter is installed on site, the electric energy meter cover box is upside down or the installation angle is less than 90 degrees, causing the force of the electric energy meter to be concentrated on one screw, causing the electric energy meter to be deformed or damaged. Because the installation angle of the electric energy meter is less than 90 degrees, the electric energy meter is fitted to the electric energy meter cover box, which increases the force on the electric energy meter cover box, causing damage to the electric energy meter cover box, or the electric energy meter is directly exposed and external, causing damage, thereby reducing the life and performance of the electric energy meter. The falling off of the screw fixing part will also cause the wiring part to be deformed by stress, causing the electric energy meter to heat up or directly malfunction. At the same time, because the electric energy meter is not fixed stably, it may fall and injure the installer sometimes. Through the device provided by the present application, the electric energy meter can be made close to the electric energy meter cover box, and its installation angle is 90 degrees, thereby avoiding the occurrence of the above problems.

[0060] The above specific implementation methods further explain in detail the purpose, technical solutions and beneficial effects of the embodiments of the present application. It should be understood that the above are only specific implementation methods of the embodiments of the present application and are not used to limit the protection scope of the embodiments of the present application. Any modifications, equivalent substitutions, improvements, etc. made on the basis of the technical solutions of the embodiments of the present application should be included in the protection scope of the embodiments of the present application.
