Description

Technical Field

[0002] Levels such as (bubble) levels are used to determine the levelness of a structure, surface or workpiece. In use, the level is placed on or in contact with the surface to be measured, and the user observes the position of the bubble in the vial relative to the mark indicating the levelness of the structure, surface or workpiece. This can be similar to measuring the flatness of a building surface, which varies according to building stress changes, and the displacement deformation of the building structure needs to be measured, which requires a portable level measuring instrument for detection;

[0003] In the bubble level in the prior art, such as CN207300236U, the utility model provides a level and a level and ruler system, the level may include one or more anti-skid structures, the anti-skid structure may be a collar formed of a high friction polymer material at least partially surrounding the level vial, the collar may be co-molded with the material of the vial surrounding piece;

[0004] The level may be a relatively small level having a length of less than 14 inches, and the level may include a groove for receiving a ruler, the groove design alone or in combination with a collar may allow a relatively short level to support a relatively long ruler, the level and ruler system may include a level and a ruler positioned within a channel of the level, wherein the ruler is positioned within the channel at an angle relative to a vertical plane; and a maximum length of the ruler is at least twice a maximum length of the level;

[0005] In the above-mentioned patent, when in use, the measuring ruler is used in conjunction with three sets of fixed-angle levels, the angles of which are fixed and cannot be adjusted. When measuring buildings, the angles of their building surfaces are different, it is inconvenient to adjust the angles during inspection, the measurement flexibility is poor, and the built-in level is inconvenient to replace.
