The invention discloses a measuring tool for measuring distance and angle, which includes a base and a first and second measuring rods which can be stretched and arranged in the groove of the base, and the first and second measuring rods are connected by a fixed pin It can be installed on the base in a manner that can be rotated relative to the base, and the measuring tool also includes a first length for measuring the length of the first measuring rod, a second length ruler for measuring the length of the second measuring rod, and a second length ruler for measuring the length of the second measuring rod. An angle ruler for obtaining the angle value between the first measuring rod and the second measuring rod. Based on the measured length and angle values, the straight-line distance between these two points, or the distance along a certain measuring rod direction, can be calculated through a suitable cosine function formula. The measuring tool has a simple structure, is easy to carry, and measures conveniently and accurately.
Description
technical field [0001] The invention relates to a measuring tool, in particular to a measuring tool used in the automotive field that can measure distance and angle. Background technique [0002] In the actual operation of vehicle development, it is often necessary to measure some key dimensions on the real vehicle, such as seat height and leg room, which represent human comfort, shoulder space, which represents lateral space, and the height of parts from the ground. If you use a simple tape measure and ruler, the accuracy of some dimensions is not high when measured with these tools; in addition, due to the narrow space in the car, the space for measuring tools to operate is often relatively small, and some dimensions are difficult to measure. [0003] Therefore, it is necessary to provide improvements to overcome the technical problems existing in the prior art. Contents of the invention [0004] The main technical problem to be solved by the present invention is to pro...
