Detailed Implementation

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] Example 1

[0024] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a hardware testing fixture for an electricity meter, including:

[0025] The support plate 5 is adjustable in height and includes a base 1. An electric push rod 4 is installed on the upper end of the base 1. The output end of the electric push rod 4 is fixedly connected to the bottom of the support plate 5. When the electric push rod 4 is working, it can drive the support plate 5 to move up and down, thereby realizing the up and down movement of the simulation box 6. This allows the height of the simulation box 6 to be adjusted to meet the usage needs of staff of different heights.

[0026] To ensure the stable up-and-down movement of the support plate 5, two limiting mechanisms are also included. The limiting mechanism includes a sleeve 2 fixed on the base 1, and a guide rod 3 is slidably connected inside the sleeve 2. The guide rod 3 is fixedly connected to the bottom of the support plate 5, so as to guide the support plate 5 in the direction of up-and-down movement.

[0027] The electricity meter testing mechanism includes a simulation box 6 mounted on a support plate 5. Multiple sets of electrical plugs 13 are installed inside the simulation box 6. Each electrical plug 13 consists of two oval-shaped metal rings. A power supply board 9 is mounted on the simulation box 6, and the electrical plugs 13 are mounted on the power supply board 9. A control switch is installed on the power supply board 9. Multiple electrical plugs 13 are connected in parallel, ensuring the same voltage. During use, the electricity meter is placed inside the simulation box 6 and then pushed until the two wiring holes on the meter are fitted onto the two oval-shaped metal rings. The oval-shaped metal rings deform due to compression, and when they are located within the wiring holes, they can tightly abut against the metal plates of the meter. Installing them one by one allows for powering the meter. Since the entire device is placed on the ground, the oval-shaped metal rings are not easily detached from the meter. After testing, the meter can be easily removed by simply moving it. This is simple and convenient. After installation, the power supply board 9 is turned on, and the meter begins to operate and count.

[0028] The power supply board 9 is explained as follows: each circuit supplying power to each set of electrical plugs 13 has a load installed, such as a light bulb. The light bulb is located on the simulation box 6. When the light bulb 6 lights up, it means that the meter can be powered normally. Conversely, the meter is damaged and unqualified.

[0029] A hot air blower 7 is installed through one side of the simulation box 6. A flow equalization plate 12 is installed inside the simulation box 6 between the hot air blower 7 and the power plug 13. A cover plate 11 is rotatably installed on the simulation box 6. The end of the cover plate 11 near the hot air blower 7 is hinged to the simulation box 6. An exhaust port 8 is provided through the end of the cover plate 11 near the power plug 13. A thermometer 10 is installed on the cover plate 11. The temperature inside the simulation box 6 can be known through the thermometer 10.

[0030] Connect the electricity meter to the power plug 13 to turn on the power. The hot air blower 7 delivers hot air into the simulation box 6 to simulate the electricity meter working in a summer environment. The hot air blower 7 is further explained as consisting of a fan and an electric heating wire. The temperature of the heating element can be controlled by controlling the voltage supplied to both ends of the electric heating wire, similar to a hair dryer. This is existing technology.

[0031] After the meters are installed, cover plate 11 is closed and hot air blower 7 is turned on. Hot air blower 7 blows heat into the simulation box 6. The airflow is guided by the flow equalization plate 12 so that the hot air is evenly blown to the energized meters. Finally, the temperature inside the simulation box 6 is within a uniform range, which can be determined by thermometer 10 (this temperature can be set according to the temperature inside the meter box in the summer). After a period of time, turn off hot air blower 7 and power supply board 9, open cover plate 11, and observe whether the readings of the four meters are similar. If there is a large difference, there is a hardware problem and rework is required. Meters with similar readings are qualified.

[0032] As mentioned above, the simulation box 6 can simulate the operation of the electricity meter in a high-temperature environment in summer, detect the stable state of the hardware under high-temperature conditions, and facilitate the disassembly and assembly of the electricity meter, which is simple and convenient.

[0033] Example 2

[0034] Reference Figures 4-5 The difference between this embodiment and embodiment 1 is that, in this embodiment, the inner bottom of the simulation box 6 is provided with a T-shaped groove 14, and a T-shaped block 16 is slidably connected in the T-shaped groove 14. The flow equalization plate 12 is installed on the T-shaped block 16, and the flow equalization plate 12 slides against the inner wall of the simulation box 6. The inner bottom of the T-shaped groove 14 is provided with multiple locking holes 15. A locking pin 17 is slidably connected to the T-shaped block 16. The locking pin 17 is slidably connected in one of the locking holes 15. A spring 18 is fixed on the locking pin 17 and the T-shaped block 16. In order to ensure the stability of the meter installed on the power plug 13, the tester can pull the locking pin 17 upward to make it disengage from the locking hole 15. At this time, the T-shaped block 16 is no longer limited. Moving the locking pin 7 drives the T-shaped block 16 and the flow equalization plate 12 to move, so that the flow equalization plate 12 abuts against the meter. In this way, the meter can be limited and its stability can be ensured.

[0035] The current equalization plate 12, which is in contact with the meter, blows hot air onto the meter, while other parts of the meter are exposed to hot air. This mainly provides an environmental space for the meter, so the impact on the meter's stability can be ignored, and the meter can still operate in high-temperature environments in summer.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
