Three-dimensional measurement ruler

Abstract

The invention relates to a three-dimensional measurement ruler which consists of cuboid aluminium boxes, a rotator, a plastic graduated scale, a graduated disc, a level bubble, a compass and a hook. The three-dimensional measurement ruler is characterized in that the cuboid aluminium box and the cuboid aluminium box are connected by the rotator; the compass is mounted on the upper surface of the rotator; the level bubble is embedded at the very centers of the compass and the rotator; the graduated scale capable of rotating and the fixed graduated disc are embedded on the lateral surface of onecuboid aluminium box; the hook is mounted at the upper end of the graduated scale; a switch, a left regulation point, a yellow light, a green light, a red light, a color light, a red light, a green light, a yellow light and a right regulation point are respectively mounted on the upper surfaces of the cuboid aluminium boxes; and a battery box, a magnet, laser lights and eight mercury switches arealso mounted inside the cuboid aluminium boxes. When the three-dimensional measurement ruler is used for measuring levelness, the three-dimensional measurement ruler not only is high in accuracy, high in visibility and convenient and visual to use, but also is very good in measurement effect.

Description

One technical field [0001] The invention is a three-dimensional measuring rule specially designed and manufactured for construction, advertising, decoration, decoration, carpenters, bricklayers and teaching. 2. Background technology [0002] At present, master masons all use a level ruler, and usually look at whether the bubble is "centered" to judge whether the line or (surface) is level. Due to working in a muddy, dusty environment, and the masters use muddy hands to touch, the level is often blurred, it looks very difficult, and sometimes even tears can be seen. Experience and feeling, and the method of observing the "center" of the blisters with the naked eye to judge the level itself is not accurate. In addition, the levels they use cannot be compressed, cannot be dropped, and are prone to deformation, which directly affects the quality of the project. From this, I designed and produced a three-dimensional measuring ruler. Three invention content [0003] The purpose of th...

Problems solved by technology

Due to working in a sandy and dusty environment, and the masters touch it with muddy hands, the level is often blurred, it looks very difficult, and sometimes it even tears, so you can only rely on it. Experience and feeling, and the method of judging the level by observing the "center" of the blister with the naked eye is not very accurate

In addition, the level they use cannot be compressed, cannot be dropped, and is prone to deformation, which directly affects the quality of the project
