A clamping device for electric meter testing

Abstract

The invention provides a clamping device for electric meter detection. The cross section of a sliding groove is in a shape of a Chinese character ao, a fixed substrate is arranged on an opening surface of the sliding groove, a cylinder body is arranged on the fixed substrate, a fastening bolt enables the cylinder body and the fixed substrate to be fastened on the opening surface of the sliding groove, an operating rod is formed by smoothly connecting a vertically downward section, a bending section and an obliquely downward section in head-to-tail mode, the upper portion of the operating rod is hinged to two ear plates on the lower portion of the cylinder body through a first shaft, the upper portion of a push rod is hinged to the bending section of the operating rod through a second shaft, the upper portion of a push block for pushing an electric meter downward to be inserted in a testing hole is hinged to the lower portion of the push rod through a third shaft, a sliding plate is located between the opening surface of the sliding groove and the bottom surface of the push block, and a clamping bolt enables the push block and the sliding plate to be movably fixed on an opening of the sliding groove. The clamping device can exert pushing force on the electric meter so as to enable the electric meter to be inserted in the testing hole to complete testing, and has the advantages of saving labor and being convenient to operate and accurate in electric meter positioning.

Description

technical field [0001] The invention relates to an auxiliary tool for electric meter detection, in particular to a clamping device for electric meter detection. Background technique [0002] The watt-hour meter calibrator is a portable device specially designed and developed for on-site calibration sheets, three-phase active and reactive power inductive and electronic watt-hour meters and other electrical instruments. The device applies high-precision sampling technology, combined with the latest digital signal processing methods, and provides a convenient and efficient solution for on-site calibration of energy meters and other electrical instruments. Mainly used in: teaching equipment, scientific research, commodity inspection, public security fire protection, safety production; belongs to the physical classification. [0003] The following items should be paid attention to when using the calibration table: [0004] 1. Before the equipment is energized and used, it shoul...

[0006] 3. It is strictly forbidden to press the Ua / external power supply selection switch repeatedly when the equipment is powered on;

[0007] 4. It is strictly forbidden to touch the terminals on the panel with hands when the equipment is powered on;

[0015] The current quality proofreading process of finished electric meters is basically tested on the operating table. On the standard operating table, the electric meter needs to be inserted and fixed on the test hole, and most of the testers in the testing process are women. Due to the influence of physiological factors, the electric meter The weight and difficulty of insertion are a huge challenge for women, and it is also difficult to accurately align the meter with the test hole
