[0001] The utility model relates to the technical field of electric energy meters, in particular to a prepaid electric energy meter structure. Background Art
[0002] An electric energy meter is an instrument used to measure electric energy, also known as a watt-hour meter, a kilowatt-hour meter, or a meter for measuring various electrical quantities. In order to improve the national electricity consumption efficiency and rationally utilize electric power resources, the electricity consumption of users is charged by time-sharing, and a prepaid electric energy meter is used for charging.
[0003] Most prepaid electric energy meters are card-swipe type. An insertion slot for swiping the card is provided on the electric energy meter. The staff inserts the card into the insertion slot to swipe the card and then takes it out after five seconds. However, during use, after the staff swipes the card, the card is inconvenient to store. Usually, the user finds a separate place to store it. In the case of storing it in other places, it is easy to forget and cannot be found when used next time. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a prepaid electric energy meter structure to solve the above technical problems.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.
[0024] As Figures 1 - 4 shown, a prepaid electricity meter structure includes an electricity meter body 1. On one side of the electricity meter body 1, there is an insertion slot 6 for swiping cards. On one side of the electricity meter body 1, a protective cover plate 2 hinged and matched with the insertion slot 6 is provided. After the protective cover plate 2 is closed, the insertion slot 6 is blocked, effectively preventing flying insects or impurities from entering the insertion slot 6. On one side of the electricity meter body 1, a storage box 3 for storing cards is fixedly provided. After swiping the card, the staff can store the card in the storage box 3, which is convenient for next use and avoids storing the card in other places, where it is easy to forget the storage location over a long time and it is relatively troublesome to find. On one side of the upper end of the storage box 3, a box cover 4 is hinged. Both the box cover 4 and the protective cover plate 2 are hinged and matched with the outside of the electricity meter body 1 through a reset hinge. On one side of the electricity meter body 1, a limiting component matched with the protective cover plate 2 and the box cover 4 is provided.
[0025] Further, the limiting component includes a mounting block 7 fixedly arranged on one side of the electricity meter body 1 and a sliding groove 14 opened in the middle of the mounting block 7. A limiting plate 8 for restricting the flipping and opening of the protective cover plate 2 is slidably arranged inside the sliding groove 14. A fixing plate 12 is fixedly arranged inside the sliding groove 14. A sliding rod 9 is movably penetrated through the middle of the fixing plate 12. One end of the sliding rod 9 is fixedly provided with an end plate 10. A spring 11 is arranged between the end plate 10 and the fixing plate 12. The other end of the sliding rod 9 is fixedly connected with the limiting plate 8. A limiting block 13 is arranged on one side of the limiting plate 8. A limiting groove 5 matched with the limiting block 13 is opened on the outer surface of the box cover 4. The cross section of the limiting block 13 is triangular. The end face on the side of the limiting plate 8 away from the limiting block 13 is beveled. During use, the staff flips the box cover 4 upwards to open it. During this process, the box cover 4 will squeeze the limiting block 13 to make the limiting block 13 move, and drive the limiting plate 8 to slide along the sliding groove 14. The sliding of the limiting plate 8 makes one end of the limiting plate 8 gradually move away from the protective cover plate 2, releasing the limiting constraint on the protective cover plate 2. The protective cover plate 2 flips and opens under the action of the reset hinge. Then, the box cover 4 is further flipped so that after the limiting block 13 is aligned with the limiting groove 5, under the reset action of the spring 11, the limiting plate 8 and the limiting block 13 are driven to move, so that the limiting block 13 is inserted into the limiting groove 5, achieving the effect of limiting the opening of the box cover 4. Furthermore, the staff can take out the card from the storage box 3 and insert it into the card slot 6 for card swiping. After the card swiping is completed, the card is put back into the storage box 3, and then the protective cover plate 2 is closed. During the closing process of the protective cover plate 2, the beveled end of the limiting plate 8 is squeezed, so that the limiting plate 8 and the limiting block 13 move, and further the limiting block 13 is separated from the limiting groove 5. Then, under the action of the reset hinge, the box cover 4 flips and closes. When the protective cover plate 2 is completely closed, at this time, the limiting plate 8 returns to its original state under the reset action of the spring 11 and abuts against the side wall of the protective cover plate 2, achieving the effect of limiting and constraining the protective cover plate 2.
[0026] Further, a handle is arranged on the outer surface of the box cover 4, which is convenient for the staff to hold the handle for operation.
[0027] Further, one end of the sliding rod 9 is fixedly connected with the limiting plate 8 by threads. The outer surface of one end of the sliding rod 9 is threaded. A threaded hole matched with the end of the sliding rod 9 is opened on the outer surface of the limiting plate 8. The end plate 10 is circular and the outer diameter value is greater than the width value of the sliding groove 14. During use, it is convenient to install and disassemble the sliding rod 9 and the limiting plate 8.
[0028] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
