Technical Field

[0001] This utility model relates to the field of verification and testing technology, specifically to a mobile energy meter test stand. Background Technology

[0002] Mobile energy meter test racks are essential tools in power systems for testing the performance and accuracy of energy meters. Traditional test racks are typically fixed in place, immobile, and complex to operate, making them unsuitable for rapid on-site testing and multi-point testing. With the power industry's increasing demands for equipment testing efficiency and flexibility, there is an urgent need for a lightweight, mobile, and easy-to-operate energy meter test rack to quickly complete energy meter calibration and testing in different locations, thereby improving the operational efficiency and reliability of the power system.

[0003] Patent publication number CN211955797U discloses an electricity meter test frame, including a test frame body with a multi-layer structure. The test frame body has multiple test slots, and each test slot has an electricity meter placement slot. The bottom of the electricity meter placement slot has a tail seat, which is welded to the electricity meter placement slot by a spring. The upper end of the electricity meter placement slot has multiple shock-absorbing rods, the upper end of which is fixedly connected to the electricity meter placement slot. The lower end of the shock-absorbing rod has an elastic plate.

[0004] To address the issues of complex operation and insufficient stability, existing technologies employ multiple shock-absorbing rods at the top of the meter placement slot. The upper ends of these rods are fixedly connected to the slot, while the lower ends are fitted with elastic plates. This method of using shock-absorbing rods and elastic plates still presents challenges such as inconvenient movement, difficulties in initial calibration, aging, and re-inspection, leading to low work efficiency and limited device flexibility.
