In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0021] As Figures 1 - 3 This is a schematic structural diagram of a rail-type electric energy meter according to a preferred embodiment of the present utility model. In this embodiment, a rail-type electric energy meter includes an electric energy meter main body 1. Operation platforms 3 are provided on both sides of the top of the electric energy meter main body 1. Terminal ports 4 are provided on the surfaces of the operation platforms 3. Through the terminal ports 4, the operator can perform operations on the wiring terminals. A groove 5 is provided on the surface of the operation platform 4 behind the terminal ports 4. A cover plate 2 is rotatably connected to the opposite position of the operation platform 3 on the top of the electric energy meter main body 1. A support device 6 for supporting the cover plate 2 is installed on the inner wall of the cover plate 2 at the position opposite to the groove 5. Through the support device 6, the operator can support the cover plate 2 during the operation of the wiring terminals. A storage block 7 for storing the support device 6 is fixedly installed on the inner wall of the cover plate 2 directly in front of the support device 6. Combining the above structural design, the problem that the cover plate 2 slides down freely and interferes with the operation of the operator during the operation process is effectively solved.

[0022] In this embodiment, the support device 6 includes a fixed block 61 and a support rod 62. The fixed block 61 is fixedly installed on the inner wall surface of the cover plate 2. A rotation position 63 is provided in the middle of the surface of the fixed block 61. A support rod 62 is rotatably connected through the rotation position 63. Rotation ports 65 are provided on both sides of the inner wall of the rotation position 63. Rotation rods 64 are symmetrically and fixedly connected above the surface of the support rod 62, and the rotation rods 64 are rotatably connected in the rotation ports 65. With this structural design, the flipping function of the support rod 62 is realized.

[0023] In this embodiment, a storage groove 71 is provided on the surface of the storage block 7 at the position opposite to the support rod 62. A convex bump 72 is fixedly connected to the inner wall of the storage groove 71. The surface of the convex bump 72 is in contact with the surface of the support rod 62, playing a role in fixing the support rod 62. Combining this structural design, when the cover plate 2 is turned down, the support rod 62 can be stored, preventing the cover plate 2 from not being able to be turned down due to the interference of the support rod 62, resulting in the cover plate 2 being unable to protect the wiring terminals.

[0024] In this embodiment, the bottom surface of the support rod 62 is in contact with the surface of the groove 5, and the support for the cover plate 2 is realized through the setting of this structure.

[0025] Working principle

[0026] During specific use, when the operator needs to operate on the wiring terminal, first turn up the cover plate 2, pick out the support rod 62 from the storage groove 71, and turn the support rod 62 downward so that the bottom surface of the support rod 62 is in contact with the surface of the groove 5, thereby completing the support for the cover plate 2; similarly, when the operator finishes operating on the wiring terminal, take out the support rod 62 from the groove 5 so that the bottom surface of the support rod 62 is not in contact with the surface of the groove 5, and then turn the support rod 62 upward and buckle it into the storage groove 71 to complete the storage and fixation of the support rod 62.

[0027] The above content further elaborates on the present utility model in combination with specific embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model pertains, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the protection scope determined by the claims submitted for the present utility model.
