[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0022] Please refer to Figures 1-7The utility model provides a technical scheme: a wall flatness detection device for building construction, including the front side of the ruler board 1 is equipped with the installation groove 2, the inside installation of installation groove 2 has level bubble 3, one side of installation groove 2 is equipped with recess 4, the inside installation of recess 4 has the protective plate 5, the side of protective plate 5 is fixed with spring 6 away from installation groove 2, and the end of spring 6 is fixedly connected with the inner wall of recess 4, and the top of installation groove 2 is equipped with through slot 7, and the top of through slot 7 is equipped with sliding slot 8, and the inside installation of sliding slot 8 has sliding rod 9, and the bottom of sliding rod 9 is fixed with connecting block 10, and the lower end of connecting block 10 is fixedly connected with the top of protective plate 5 through the inside of through slot 7, and the outside of sliding rod 9 is installed in the outside of ruler board 1 with nut 11.
[0023] The outside of the protective plate 5 and the inside of the recess 4 are mutually attached, and the protective plate 5 and the recess 4 form a sliding connection, and the protective plate 5 and the installation groove 2 form a sliding connection, which ensures that the protective plate 5 can normally move in the recess 4, and the protective plate 5 is stored in the recess 4, which does not hinder the observation of the level bubble 3.
[0024] The outside of the sliding rod 9 and the inside of the sliding slot 8 are mutually attached, and the sliding rod 9 and the sliding slot 8 form a sliding connection, which ensures that the sliding rod 9 can move in the sliding slot 8, so that the sliding rod 9 can drive the connecting block 10 to move.
[0025] The outside of the connecting block 10 and the inside of the through slot 7 are mutually attached, and the connecting block 10 and the through slot 7 form a sliding connection, which ensures that the connecting block 10 can move in the through slot 7, so that the connecting block 10 can drive the protective plate 5 to move.
