Description

Technical Field

[0001] The utility model relates to a portable Leeb hardness tester, belonging to the technical field of detection devices. Background Art

[0002] In medium and thick plate steel enterprises, according to the performance requirements of steel grades, it is necessary to measure the surface hardness of steel plates. The commonly used measuring device is a portable Leeb hardness tester. The portable Leeb hardness tester consists of a host, connecting wires and impact components. The measurement object is a steel plate laid flat on the ground. When measuring, the measurer needs to squat at the measurement position, place the host on the ground of the measurement area, press the fixed impact component vertically at the measurement position with one hand, press the loading sleeve with the other hand, and then press the release button to measure. Finally, check the measurement value of the host to complete a measurement. During large-scale production in steel enterprises, steel plates are placed on the ground of the factory building, and the measurer needs to squat frequently to complete the measurement of multiple positions and multiple steel plates. This increases the work intensity of the measurer, and at the same time causes certain damage to the knee joints of the measurers who have been engaged in hardness measurement for a long time. The measurement efficiency is also not high, and often two measurers are required to take turns to measure. Utility Model Content
