Abstract
A novel set square is provided with a protractor, and the protractor comprises corresponding angle scale marks; a closed arc-shaped cavity is arranged along the angle scale line of the protractor, and the closed arc-shaped cavity forms a semicircular ring with fixed curvature; be equipped with liquid, bubble in the cavity, its characterized in that: a small ball is also arranged in the arc-shaped cavity; the diameter of the closed arc-shaped cavity is smaller than the diameter of the circular section of the closed arc-shaped cavity, and the closed arc-shaped cavity can sink in liquid in the closed cavity. The pellet is a spherical solid. The small ball is a liquid drop formed by a solution which is not dissolved in the liquid filled in the closed cavity, and the liquid drop is formed by a solution with the density which is higher than that of the liquid filled in the closed cavity.
Description
Technical Field
A novel set square belongs to the field of measuring tools.
Background
The protractors arranged on the current set square cannot make horizontal lines and vertical lines on a blackboard, and cannot detect whether a plane is horizontal (such as whether a desktop is horizontal). In order to better make horizontal lines, vertical lines, and lines that are at a certain angle with respect to the vertical lines and the horizontal lines, it has been designed to place a ball in the toroidal cavity. However, the ball will swing to the left and right during measurement, and it takes a certain time to stop. And it cannot be judged whether the desk top is level like the ground. In order to overcome the problems, the inventor designs the ball belt to move in a damping mode, so that the ball can be stopped quickly, and a user can read the ball quickly and accurately.
Has the advantages that: the angle can be rapidly and accurately indicated, the horizontal measuring function of the triangular plate is expanded, and the levelness of planes such as the ground, a desktop and the like can be measured due to the existence of air bubbles.
