Abstract
Description
Technical Field
[0001] This utility model relates to the field of wiring devices, and in particular to a wiring device for testing electricity meters. Background Technology
[0002] An electricity meter, also known as a kilowatt-hour meter or energy meter, is an instrument used to measure electrical energy. Its core function is to record the cumulative value of electrical energy consumption over a certain period of time. It measures the product of current and voltage through electromagnetic induction or electronic circuits and integrates it over time to calculate the electrical energy consumed. The unit of measurement is kilowatt-hour (kW·h), which is what we commonly refer to as a "degree" in daily life.
[0003] Electricity meters can be classified according to their structure and working principle into electromechanical electricity meters and static (electronic) electricity meters; according to their connection method into direct connection type and indirect connection type (connected via current transformer); and according to the metering object into active energy meters, reactive energy meters, maximum demand meters, multi-tariff (time-of-use) energy meters, multi-function energy meters, smart energy meters, etc. In addition, electricity meters have some key parameters, such as reference voltage, reference frequency, basic current and rated maximum current, meter constant, and accuracy class. These parameters collectively describe the operating characteristics and performance of the electricity meter.
[0004] During the production and processing of electricity meters, performance testing is required. In actual operation, multiple electricity meters are placed side by side on a workbench, and workers insert the positive and negative terminals into the electricity meters to complete the wiring work. According to the performance of the electricity meters displayed by the tester, this type of test wiring device requires manual operation of inserting and unplugging each electricity meter one by one. Pressing the terminals with your hands for a long time can easily cause muscle soreness.
[0005] Therefore, it is necessary to provide a new wiring device for testing electricity meters to solve the above-mentioned technical problems. Utility Model Content
[0006] To solve the above-mentioned technical problems, this utility model provides a wiring device for testing electricity meters.
[0007] The electricity meter testing wiring device provided by this utility model includes a working frame, on which a placement frame is fixed, and multiple clamping devices are installed on the placement frame.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] Please refer to the following: Figures 1-4 ,in, Figure 1 A schematic diagram of the electrical energy meter testing wiring device provided by this utility model; Figure 2 for Figure 1 A partial structural diagram of the structure shown; Figure 3 for Figure 1 A schematic diagram of the clamping component in the structure shown; Figure 4 for Figure 3 The diagram shows a cross-sectional view of the structure.
[0023] In the specific implementation process, such as Figures 1-4 As shown, the device includes a work frame 1, on which a placement frame 2 is fixed. Multiple clamping devices are installed on the placement frame 2. Each clamping device includes two clamping members, and the distance between the two clamping members is adjustable. A reciprocating moving device is also installed on the work frame 1. A lifting member is installed on the moving end of the reciprocating moving device, and two clamping rings 3 with adjustable spacing are installed on the lifting end of the lifting member.
[0024] It should be noted that the detector can be installed on the transmission frame 11, specifically by bolts. The detector model is ZH4444. Considering the problem of wire tangling when the detector moves, an external power supply can be used directly. The external power supply is placed on the detector and electrically connected to the detector through a wire. The detector does not move relative to the external power supply during use.
[0025] The clamping components include a mounting plate 4, a clamping block 5, and a spring 6. The mounting plate 4 is placed on the placement frame 2. A receiving groove 7 is provided on the mounting plate 4. The clamping block 5 is slidably arranged in the receiving groove 7. The top of the clamping block 5 is an upward inclined structure. The two ends of the spring 6 are respectively fixed to the clamping block 5 and the bottom wall of the receiving groove 7. When the electricity meter is placed between the two clamping components, the inclined structure of the clamping blocks 5 on both sides is squeezed when the electricity meter moves down, causing the clamping blocks 5 to move into the receiving groove 7. The spring 6 is compressed, and the electricity meter is positioned by the clamping block 5.
[0026] The reciprocating moving device includes a mounting frame 8, a first threaded rod 9, a guide rod 10, a transmission frame 11, and a first motor 12. The mounting frame 8 is fixed on the working frame 1. The first threaded rod 9 is rotatably connected to the mounting frame 8 and threadedly connected to the transmission frame 11. The guide rod 10 is fixed on the mounting frame 8 and movably passes through the transmission frame 11. The first motor 12 is fixed on the mounting frame 8, and its output end is fixed to one end of the first threaded rod 9. The lifting component is an electric cylinder 13, which is fixed on the transmission frame 11. An adjustment device is installed on the telescopic end of the electric cylinder 13, and two clamping rings 3 are installed on the adjustment device. The first motor 12 drives the first threaded rod 9 to rotate, causing the transmission frame 11 to move the terminals. When the device moves to the position of the electricity meter, the electric cylinder 13 drives the clamping frame 16 to move downward, so that the two terminals are inserted into the wire groove of the electricity meter, facilitating the testing of the electricity meter.
[0027] The placement rack 2 has a sliding hole 14 on one side. Multiple sliders 15 are installed in the sliding hole 14 at the positions of multiple clamping parts. Bolts are threaded onto the sliders 15. One end of the bolt can be pressed against the mounting plate 4. The position of the sliders 15 can be adjusted according to the size of the electricity meter. After the sliders 15 are moved to the appropriate position, the bolts on them can be rotated so that one end of the bolt can be pressed against the mounting plate 4.
[0028] The adjustment device includes a clamping frame 16, a second threaded rod 17, a second motor 18, and two transmission plates 19. The clamping frame 16 is fixed to the telescopic end of the electric cylinder 13. The second threaded rod 17 is rotatably connected to the clamping frame 16. The two ends of the second threaded rod 17 are respectively provided with left and right threads. The two transmission blocks are respectively threaded to the left and right threads. The two transmission blocks are respectively fixedly connected to the two clamping rings 3. The second motor 18 is fixed to the clamping frame 16. The output end of the second motor 18 is fixedly connected to the second threaded rod 17. The second motor 18 can drive the second threaded rod 17 to rotate, which facilitates the adjustment of the distance between the two clamping rings 3 to adapt to different energy meters.
[0029] The working principle of this utility model is as follows: When using the device, multiple energy meters are placed sequentially on the clamping device, with the energy meters positioned between two clamping parts. As the energy meters move downwards, the inclined structure of the clamping blocks 5 on both sides is squeezed, causing the clamping blocks 5 to move into the receiving groove 7. The spring 6 is compressed, and the energy meters are positioned by the clamping blocks 5. The detector is installed on the transmission frame 11, and the two terminals of the detector are inserted into the two clamping rings 3. Bolts can be threaded onto the clamping rings 3. By tightening the bolts, the terminals are installed on the clamping rings 3. In addition, the second motor 18 can drive the second threaded rod 17 to rotate, which facilitates the adjustment of the distance between the two clamping rings 3. The first motor 12 drives the first threaded rod 9 to rotate, causing the transmission frame 11 to move the terminals. When the terminals move to the position of the energy meters, the electric cylinder 13 drives the clamping frame 16 to move downwards, so that the two terminals are inserted into the wire groove of the energy meters, which facilitates the testing of the energy meters.
[0030] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
