The invention provides a reflection bubble horizontal ruler. The reflection bubble horizontal ruler comprises a long-shaped ruler body, wherein the long-shaped ruler body comprises a first surface and a second surface; a cavity is formed between the first surface and the second surface and an opening is formed in the cavity on the second surface; a horizontal ruler body arranged in the cavity comprises a non-light-proof body ruler body provided with an inclined plane and a first observation surface, and a bubble assembly arranged in the ruler body; the vertical axis of the bubble assembly is vertical to the first surface; the first surface is arranged between the first end of the bubble assembly and a detected surface; the first observation surface is arranged between the second end of the bubble assembly and a user; an image of the bubble assembly is formed by the reflection of the inclined plane; and the user can observe the image of the bubble assembly, which is reflected by the inclined plane, through the first observation surface. According to the reflection bubble horizontal ruler provided by the invention, light is reflected when passing through an interface, and the user can observe the bubble assembly from the front surface when the perpendicularity is measured; and the horizontal ruler is molded and manufactured in one step, and extra assembling and calibration are not needed, so that the manufacturing is simple and the cost is low.
Description
technical field [0001] The invention relates to a reflective bubble level, which belongs to measuring tools. Background technique [0002] The water bubble level is a measuring tool used to measure the levelness and vertical plane of the surface of the object. Generally, the level is based on the bottom surface as the reference plane, and the bottom surface of the level is placed on the surface to be measured. By observing the corresponding The level bubble is used to judge whether the measured surface is horizontal or vertical. [0003] When you want to measure whether a plane is level, place the spirit level on the measured plane and observe whether the level bubble on the 180° water bubble assembly moves to the middle of the two scales on the level bubble. If it is in the middle, the measured plane is level, otherwise it is Measuring plane is not level. [0004] When you want to measure whether a plane is vertical, put the level bar vertically against the measured plane...
