Description

Technical Field

[0001] This application relates to the field of electricity meter testing technology, and more specifically, to an electricity meter metering and testing device. Background Technology

[0002] Electricity meter testing equipment is specifically designed to test the metering accuracy, functional integrity, and operational stability of electricity meters. By simulating actual electricity consumption scenarios, it accurately collects the metering data and compares it with the output value of a standard metering device to determine whether the electricity meter meets the requirements of metrological regulations.

[0003] In related technologies, to address the issue of needing to connect power cables to view equipment data, patent CN206710587U provides a testing and operation platform for metering terminal equipment. This platform features a specially designed housing structure for specific metering terminal equipment, comprising a first housing structure and a second housing structure. The power interface of the first housing structure includes one live wire port and one neutral wire port for housing a single-phase energy meter or concentrator. The power interface of the second housing structure includes three live wire ports and one neutral wire port for housing a three-phase four-wire energy meter or load control terminal. Each port is movably connected, and the housing structure contains ports connected to a composite carrier. This allows for direct power connection to meters such as energy meters, or connection to the load carrier port for faster and more convenient viewing of metering terminal equipment data and other operations.

[0004] Although the existing technical solutions mentioned above include a housing structure to enable faster and more convenient viewing of data from metering terminal equipment, setting up several housing structures dedicated to specific metering terminal equipment can easily occupy a lot of space, leading to an increase in the size of the test equipment and reducing portability. Furthermore, the limited number of housing structures makes it difficult to accommodate the diverse range of electricity meters on the market, resulting in poor versatility.

[0005] In view of this, we propose an electricity meter metering and testing device. Utility Model Content

Detailed Implementation

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] Reference Figure 1 , Figure 2 and Figure 4 This application discloses an electricity meter metering test device, including a test box 1. The top of the test box 1 is provided with an inclined surface 11 for supporting the electricity meter body 100. Two positioning plates 2 are slidably arranged on the inner side of the inclined surface 11 for clamping and positioning the electricity meter body 100. A bracket 3 is slidably arranged on the top of the test box 1. The bracket 3 is arranged parallel to the inclined surface 11. A lower pressure plate 4 is slidably arranged on the top of the bracket 3. Several adjusting blocks 42 are slidably arranged on the inner side of the lower pressure plate 4 for driving the test terminals 43 to adjust the docking position. The test terminals 43 are elastically arranged at the bottom of the adjusting blocks 42. A top cover 17 is rotatably arranged on the top of the test box 1.

[0030] When testing the electricity meter body 100, the electricity meter body 100 is placed inside the inclined plane 11, so that one side of the electricity meter body 100 is close to the bottom side of the inclined plane 11, and the two positioning plates 2 clamp and position the electricity meter body 100. Then, the bracket 3 slides on the top of the test box 1, so that the lower pressure plate 4 is located on the top of the wiring terminal of the electricity meter body 100. Then, by sliding the adjusting block 42, the adjusting block 42 is aligned with the wiring terminal of the electricity meter body 100, and the lower pressure plate 4 is pressed down, which drives the test terminal 43 to move down and connect with the wiring terminal of the electricity meter body 100. This achieves the effect of quickly connecting the electricity meter body 100 to the test circuit, making the test operation more convenient. The test box 1 is equipped with metering and testing equipment, which is connected to the test terminal 43.

[0031] Reference Figure 2 , Figure 3 and Figure 4 The inner side of the test chamber 1 has sliding grooves A12 on both sides of the inclined plane 11. The bracket 3 is slidably disposed inside the sliding grooves A12. Sliding grooves B13 are formed at the bottom of the two sliding grooves A12. A connecting plate 312 is fixedly disposed at the bottom of the bracket 3. A screw 311 is rotatably disposed on the outer side of the connecting plate 312. An adjusting knob 31 is fixedly disposed at the end of the screw 311 away from the connecting plate 312. A fixing plate A15 is fixedly disposed on the outer side of the test chamber 1 by screws. The fixing plate A15 is threaded onto the screw 311. The bracket 3... A sliding hole 32 is provided on the inner side. A slider 41 is fixedly provided on the bottom of the lower pressure plate 4. The slider 41 is slidably disposed with the sliding hole 32. The top of the bracket 3 is supported by an elastic component 33. The elastic component 33 includes a connecting post 332. The connecting post 332 is fixedly disposed on the top of the bracket 3. The connecting post 332 is slidably disposed with the inner side of the lower pressure plate 4. A spring B331 is sleeved on the outer side of the connecting post 332. A limit plate 3321 is fixedly provided on the top of the connecting post 332. A handle 44 is fixedly provided on the outer side of the lower pressure plate 4.

[0032] When testing the electricity meter body 100, rotating the adjustment knob 31 causes the screw 311 to rotate, making the screw 311 threadedly engage with the fixing plate A15, which in turn moves the connecting plate 312, thereby moving the bracket 3. The bracket 3 then moves the top pressure plate 4, adjusting the docking position of the test terminals 43 so that a row of test terminals 43 are vertically aligned with the wiring terminals of the electricity meter body 100. Then, by moving the adjustment block 42, the adjustment block 42 slides inside the slider 41, thereby making each test terminal 43 correspond one-to-one with the wiring terminals of the electricity meter body 100. Then, pressing down the handle 44 causes the pressure plate 4 to descend, making the pressure plate 4 move the slider 41 inside the sliding hole 32, making the test terminals 43 dock with the wiring terminals of the electricity meter body 100. After the test is completed, the pressure plate 4 is reset by the elastic effect of the spring B331.

[0033] Reference Figure 2 , Figure 3 and Figure 5 Inside the test chamber 1, on both sides of the inclined plane 11, there are device slots 14. On the side of the two positioning plates 2 that are far apart from each other, springs A21 and sliding columns 22 are fixedly installed. The two sliding columns 22 are slidably installed inside the device slots 14. A fixing plate B16 is fixedly installed on the top of the device slots 14 by screws. A rubber pad 23 is fixedly installed on the side of the positioning plate 2 that is far away from springs A21. An anti-slip groove 231 is opened on the outer side of the rubber pad 23.

[0034] Under the elastic effect of spring A21, the two positioning plates 2 can clamp and position the electricity meter body 100. The sliding column 22 slides inside the device groove 14 to limit the movement of the positioning plate 2. By setting the rubber pad 23, damage to the electricity meter body 100 is prevented. The anti-slip groove 231 increases the friction between the rubber pad 23 and the electricity meter body 100, preventing the electricity meter body 100 from sliding.

[0035] In summary, when using the electricity meter metering and testing equipment disclosed in this application, the electricity meter body 100 is placed inside the inclined plane 11, so that one side of the electricity meter body 100 is close to the bottom side of the inclined plane 11, and the two positioning plates 2 clamp and position the electricity meter body 100. Then, by rotating the adjustment knob 31, the screw 311 is rotated, so that the screw 311 is threadedly engaged with the fixing plate A15, which drives the connecting plate 312 to move, thereby driving the bracket 3 to move. The bracket 3 drives the top pressure plate 4 to move, adjusting the docking position of the test terminals 43, so that one... The test terminals 43 are vertically aligned with the wiring terminals of the energy meter body 100. Then, by moving the adjusting block 42, the adjusting block 42 slides inside the slider 41, thereby driving each test terminal 43 to correspond one-to-one with the wiring terminals of the energy meter body 100. Then, the handle 44 is pressed down, driving the lower pressure plate 4 to descend, causing the lower pressure plate 4 to drive the slider 41 to slide inside the sliding hole 32, driving the test terminals 43 to connect with the wiring terminals of the energy meter body 100. This achieves the effect of quickly connecting the energy meter body 100 to the test circuit, making the test operation more convenient.
