Background

Levels are used by carpenters, masons, wallers, and the like to help ensure that the surface being measured is horizontal, vertical, or in a particular angular relationship to the horizontal. A typical level includes at least two vials, each for confirming whether a surface is "level," i.e., horizontal, or "plumb," i.e., vertical. The level comprises one or more measuring surfaces and a vial set in angular relation to the measuring surfaces, the vial being partially filled with a liquid, such as mineral spirits, the vial not being completely filled, thereby forming a bubble when the vial is closed. Typically, two marker rings are formed in the outside locations of the vial to visually divide the cavity into three sections of approximately equal length, with level and plumb conditions being confirmed by indicating the location of the bubble relative to the marker rings. The existing level bar may slide in the using process, so that the level bar falls off to influence the measuring precision of the air level, and therefore, an anti-skid level bar for engineering detection is provided to solve the problems.
