Tilt angle measurement device

Abstract

The invention discloses a tilt angle measurement device which comprises a vertical measurement mechanism, a horizontal measurement mechanism and a bracket, wherein the vertical measurement mechanism comprises a first height adjustment mechanism, a first fixed rod, a first movable rod, a first pointer rod and a first dial gauge; the horizontal measurement mechanism comprises a second height adjustment mechanism, a second fixed rod, a second movable rod, a second pointer rod and a second dial gauge; and the bracket comprises a support frame and a working platform. The tilt angle measurement device converts the tilt angles along the vertical measurement direction and the horizontal measurement direction of a television (TV) into deflection angles of the first pointer rod and the second pointer rod in an equivalent way and can control the deflection of a pointer by the linear motion of the movable rods along the horizontal or vertical direction, so that the tilt angle value along the vertical or horizontal direction can be obtained; and the tilt angle measurement device is high in measurement accuracy, good in stability, simple in operation and high in universality.

Description

technical field [0001] The invention relates to the field of measuring devices, in particular to an inclination angle measuring device. Background technique [0002] With the complete transformation of TVs from CRT to LED, various shapes of flat-panel TVs are rapidly emerging, and customers are particularly concerned about the tilt of flat-panel TV displays, because the tilt of the display screen affects customers' visual perception to a certain extent Therefore, when the product leaves the factory, it is necessary to check whether the inclination angle of the TV set meets the standard after the base is assembled. Existing ordinary mechanical angle rulers and angle gauges cannot meet the test requirements, and it is not easy to select the test surface for the angle tester with digital display on the TV, so the commonly used detection methods are: first, the inclination angle in the horizontal direction : Place the TV on the horizontal platform, select two approximately symm...

Problems solved by technology

Existing ordinary mechanical angle rulers and angle gauges cannot meet the test requirements, and it is not easy to select the test surface for the angle tester with digital display on the TV, so the commonly used detection methods are: first, the inclination angle in the horizontal direction : Place the TV on the horizontal platform, select two approximately symmetrical points in the horizontal direction of the TV, measure the distance from the TV to the horizontal platform and the distance between the two points, and then perform geometric calculations to measure the inclination angle in the horizontal direction; 2. The tilt angle in the vertical direction: place a vertical ruler on the horizontal platform as a reference, select two approximately symmetrical points in the vertical direction of the TV, measure the distance to the vertical reference ruler and the distance between the two points, and then perform geometric calculations , to measure the inclination angle in the vertical direction; this measurement method has a large measurement error, cumbersome operation, and takes a long time
