[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. "Buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that can meet people's production, living, learning, and public activities. During the construction of construction projects, workers need to use a measuring ruler to detect the verticality of the building walls. The existing measuring rulers need to rely on the ground as a reference surface when detecting the verticality of the wall, so most of the existing measuring rulers are equipped with support reference components. The existing support reference components are mostly composed of support rods and reference plates, which increases the overall length of the measuring ruler and is inconvenient to carry. The existing measuring rulers are not convenient for storing the support reference components inside the measuring rulers, so that they can be easily carried. Therefore, we propose a verticality measuring ruler. Utility Model Content

An opening 4 connected to the inside of the storage chamber 6 is provided at the bottom of the detection ruler 1. Under the action of the guide groove 31 and the guide block 32, the support plate 33 moves upward on the outer wall of the threaded rod 34, so that the support plate 33 and the reference plate 30 move into the storage chamber 6 through the opening 4. A stabilizing component 5 is provided in the reference plate 30.

[0017] See also Figure 2 The stabilizing component 5 includes a bidirectional screw rod 54 provided in the reference plate 30, one end of the bidirectional screw rod 54 is connected to a bearing provided on the right side wall of the reference plate 30, and the other end of the bidirectional screw rod 54 passes through the left side wall of the reference plate 30 and is connected to the rotating knob 50 provided on the outside.
