Description

Technical Field

[0001] This utility model belongs to the technical field of electricity meter calibration equipment, specifically relating to a multi-layer switchable connection and disconnection unit. Background Technology

[0002] During the manufacturing process, electricity meters undergo verification (i.e., testing and calibration) to ensure their accuracy and reliability. Electricity meters are crucial devices in the power system used to measure electricity consumption, and their accuracy directly impacts the fairness of electricity billing and the interests of users. Therefore, the verification of electricity meters is extremely important, ensuring fair transactions in the electricity market and preventing disputes and losses caused by metering errors.

[0003] During the calibration of electricity meters, the meters are transported via a pair of parallel conveyor belts, and then calibrated by a connection / disconnection unit. However, existing connection / disconnection units are mostly single-layer designs, and the number, spacing, and size of the pins on the calibration connectors vary. This means that the calibration connectors for single-phase electricity meters can only calibrate single-phase meters and cannot calibrate other types of electricity meters, such as three-phase meters, data acquisition terminals, and concentrators. In addition, when the production line changes to a calibration product that is different from the electricity meters that the connection / disconnection unit can calibrate, the corresponding calibration unit needs to be replaced, and the cables connecting the meter holder and the electrical testing equipment also need to be reconfigured. This makes each change of calibration product time-consuming and affects the normal operation of the equipment. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a multi-layer switchable connection and disconnection unit, which effectively solves the problems of limited energy meter types and inconvenient replacement in existing connection and disconnection units.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-layer switchable connection and disconnection unit, including a mounting frame, on which a lifting frame is slidably connected vertically; a movable frame is slidably connected to the lifting frame, and multiple mounting seats are arranged sequentially from bottom to top on the movable frame; a fixed base plate is detachably connected to each of the multiple mounting seats, and a pair of meter holders are fixedly connected to each of the multiple fixed base plates; a pair of wiring plug-in modules are provided on each of the multiple mounting seats, and the meter holders are provided with plug-in module pins that cooperate with the wiring plug-in modules.

[0006] Furthermore, a switching telescopic rod is fixedly connected to the mounting frame, and the telescopic end of the switching telescopic rod is fixedly connected to the lifting frame.

[0007] Furthermore, a guide rod that is slidably connected to the mounting frame is fixedly connected to the lifting frame, and a limiting block that cooperates with the mounting frame is fixedly connected to the end of the guide rod away from the lifting frame.

[0008] Furthermore, a mounting plate is fixedly connected to the lifting frame, and a calibration telescopic rod is fixedly connected to the mounting plate. The telescopic end of the calibration telescopic rod is fixedly connected to the moving frame.

[0009] Furthermore, a slide rail is fixedly connected to the lifting frame, and a slider that is slidably connected to the slide rail is fixedly connected to the moving frame.

[0010] Furthermore, a plurality of upper ear plates are fixedly connected to the fixed base plate, and a lower ear plate corresponding to the plurality of upper ear plates is fixedly connected to the mounting base. Connecting bolts are passed through the plurality of upper ear plates and the plurality of lower ear plates.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. In use, this utility model allows for the installation of multiple sets of different types of connection and disconnection units by means of multiple mounting seats arranged sequentially from bottom to top. In use, the different types of connection and disconnection units can be aligned with the energy meters on the belt conveyor by the up and down movement of the lifting frame. Then, the mounting seats and meter holders can be moved to the positions corresponding to the energy meters by the moving frame to perform the verification, thereby improving the adaptability of this application.

[0013] 2. When using this utility model, if the production line changes to a different energy meter than the one that the connection and disconnection unit can calibrate, the meter holders on different fixed base plates are installed on the wiring plug-in module. This allows the application to replace the meter holder without reconfiguring the mounting base and the cables connected to the mounting base, thereby improving the efficiency of meter holder replacement and enabling the application to switch between different energy meter calibrations more quickly.

[0016] A multi-layer switchable connection / disconnection unit, such as Figure 1 As shown, the device includes a mounting frame 5, on which a lifting frame 6 is slidably connected vertically; a movable frame 9 is slidably connected to the lifting frame 6, and multiple mounting seats are arranged sequentially from bottom to top on the movable frame 9; a fixed base plate 12 is detachably connected to each of the multiple mounting seats, and a pair of watch holders 13 are fixedly connected to each of the multiple fixed base plates 12; a pair of wiring plug-in modules 11 are provided on each of the multiple mounting seats, and the watch holders 13 are provided with plug-in module pins that cooperate with the wiring plug-in modules 11.

[0017] In use, this utility model allows for the installation of multiple sets of different types of connection / disconnection units via multiple mounting bases arranged sequentially from bottom to top. The lifting frame 6 allows different types of connection / disconnection units to be aligned with the energy meters on the conveyor belt. The moving frame 9 then moves the mounting base and meter holder 13 to the corresponding positions for calibration, improving the adaptability of this invention. Furthermore, if the production line is changed to calibrated products different from those calibrated by the connection / disconnection units, the meter holders 13 on different fixed base plates 12 are installed on the wiring plug-in module 11. This eliminates the need to reconfigure the mounting base and connected cables when changing meter holders, improving the efficiency of meter holder replacement and enabling faster switching between different energy meter calibrations.

[0018] Furthermore, in order to make the lifting frame 6 move up and down, a switching telescopic rod 1 is fixedly connected to the mounting frame 5, and the telescopic end of the switching telescopic rod 1 is fixedly connected to the lifting frame 6; the lifting frame 6 is driven to move up and down by the switching telescopic rod 1.

[0019] Furthermore, to improve the stability of the sliding of the lifting frame 6, a guide rod 2 is fixedly connected to the lifting frame 6 and slidably connected to the mounting frame 5. A limiting block 4 that cooperates with the mounting frame 5 is fixedly connected to the end of the guide rod 2 away from the lifting frame 6. The lifting frame 6 is guided to move up and down by the guide rod 2, thereby improving the stability of the lifting frame 6.

[0020] Furthermore, in order to allow the movable frame 9 to slide along the lifting frame 6, a mounting plate 8 is fixedly connected to the lifting frame 6, and a calibration telescopic rod 3 is fixedly connected to the mounting plate 8. The telescopic end of the calibration telescopic rod 3 is fixedly connected to the movable frame 9, and the movable frame 9 slides along the lifting frame 6 by the telescopic extension and retraction of the calibration telescopic rod 3.

[0021] Furthermore, to improve the stability of the sliding of the movable frame 9, a slide rail 7 is fixedly connected to the lifting frame 6, and a slider that is slidably connected to the slide rail 7 is fixedly connected to the movable frame 9. The sliding of the movable frame 9 is guided by the cooperation of the slide rail 7 and the slider.

[0022] Furthermore, to improve the stability of the connection between the fixed base plate 12 and the mounting base, a plurality of upper ear plates are fixedly connected to the fixed base plate 12, and a lower ear plate 10 corresponding to the plurality of upper ear plates is fixedly connected to the mounting base. Connecting bolts are provided on the plurality of upper ear plates and the plurality of lower ear plates 10. The fixed base plate 12 and the mounting base are fixed by the cooperation of the connecting bolts with the upper ear plates and the lower ear plates 10, thereby improving the stability of the fixed base plate 12 and the watch holder 13.

[0023] The working process of this utility model is as follows:

[0024] In use, when the electricity meter is being tested, the belt conveyor moves the electricity meter to the position corresponding to the meter holder 13, causing the switching telescopic rod 1 to extend and retract. The switching telescopic rod 1 then moves the lifting frame 6 up and down, so that different types of connection and disconnection units correspond to the electricity meter on the belt conveyor. Then, the testing telescopic rod 3 extends, and the testing telescopic rod 3 moves the moving frame 9 along the lifting frame 6 through the cooperation of the slider and the slide rail 7. The moving frame 9 moves the mounting base and the meter holder 13 to the position corresponding to the electricity meter for testing, thereby improving the adaptability of this application.

[0025] When replacing the watch holder 13, the disassembly process of the watch holder 13 is as follows: Remove the connecting bolts to separate the fixing base plate 12 from the mounting base. The fixing base plate 12 drives the plug module pins on the watch holder 13 to separate from the wiring plug module 11, thereby disassembling the watch holder 13. The installation process of the watch holder 13 is as follows: Align the plug module pins on the watch holder 13 with the wiring plug module 11, and drive the plug module pins to descend and connect with the wiring plug module 11 through the fixing base plate 12 and the watch holder 13. Connect the fixing base plate 12 and the mounting base with connecting bolts to achieve the installation of the watch holder 13.
