[0025] Example 1

[0026] See also Figures 1 to 6 The utility model provides a wall flatness detection ruler for construction, comprising a main ruler 1 and a secondary ruler 2 rotatably arranged at one end of the main ruler 1, a groove 3 is provided on one side of the main ruler 1, and the secondary ruler 2 rotates in the groove 3. When the secondary ruler 2 is in an unfolded mode, a side wall of the secondary ruler 2 is flush with a side wall of the main ruler 1 away from the groove 3. When the secondary ruler 2 is folded, the secondary ruler 2 is located in the groove 3.

[0027] A notch is provided at the rotating end of the secondary ruler 2. When the secondary ruler 2 is unfolded, the notch can collide with the main ruler 1, thereby limiting the position of the secondary ruler 2 and ensuring that the secondary ruler 2 is always flush with the main ruler 1.

[0028] A control rod 4 is rotatably arranged on both sides of the secondary ruler 2, and the connection between each control rod 4 and the secondary ruler 2 is close to the rotation end of the secondary ruler 2;

[0029] One end of each control rod 4 away from the secondary scale 2 is rotated to set a swing arm 5, and the swing arm 5 is rotatably connected to the main scale 1.

[0030] By rotating the control rod 4, the position between the secondary scale 2 and the primary scale 1 can be adjusted. When the secondary scale 2 is unfolded, the control rod 4 can simultaneously fix the state of the secondary scale 2, ensuring that one side wall of the secondary scale 2 is always flush with one side wall of the primary scale 1.

[0031] A bump 6 is provided at each end of each control rod 4. One bump 6 is rotatably connected to the secondary scale 2, and the other bump 6 is rotatably connected to the swing arm 5.

[0032] A notch 7 is provided at one end of the primary scale 1 near the rotation axis of the secondary scale 2, and two notches 7 are provided at the other end. The bumps 6 at both ends of the control rod 4 respectively correspond to one of the notches 7.

[0033] When the secondary scale 2 is in different states of being unfolded or folded, the position of the bump 6 in the notch 7 will change accordingly, playing a role in limiting and stabilizing the structure. For example, when the secondary scale 2 is unfolded, one bump 6 far from the secondary scale 2 is in a notch 7 close to the secondary scale 2, which can ensure the stability when the secondary scale 2 is flush with the primary scale 1; when the secondary scale 2 is folded, the bump 6 will move to the position of another notch 7 to ensure the firm placement of the secondary scale 2 in the groove 3.

[0034] Two sets of buckles 8 are respectively provided on both sides of the primary scale 1. Each set of buckles 8 includes a base 9 fixedly connected to the primary scale 1. A handle 10 is rotatably provided on the base 9, and a hook 11 is rotatably provided in the middle of the handle 10;

[0035] The hook 11 is detachably connected to the control rod 4.

[0036] Two limiting rods 12 are respectively fixedly provided at both ends of the control rod 4. The hook 11 of each buckle 8 is detachably connected to one of the limiting rods 12.

[0037] When it is necessary to fix the position or state of the secondary scale 2, rotate the handle 10 on the base 9. The hook 11 rotatably provided in the middle of the handle 10 moves as the handle 10 rotates. When it is necessary to fix the control rod 4, connect the hook 11 to the control rod 4. Specifically, the hook 11 is detachably connected to the limiting rods 12 respectively fixedly provided at both ends of the control rod 4.

[0038] When the secondary scale 2 is in the unfolded state, the control rod 4 can be fixed by the buckle 8, so as to maintain the state of the secondary scale 2 being flush with the primary scale 1 and ensure the stability of the leveling ruler when detecting a large-area wall surface;

[0039] When the secondary scale 2 is in the folded state, the control rod 4 can also be fixed at a suitable position by using the buckle 8 to prevent the secondary scale 2 from shaking in the groove 3, which is convenient for carrying and storing.

[0040] When the utility model is in use, the auxiliary ruler 2 can be selected to be unfolded according to the actual situation to detect a large-area wall surface, or it can be folded to adapt to a narrow area or for easy carrying and storage. By rotating the control rod 4, the position between the auxiliary ruler 2 and the main ruler 1 can be adjusted. When the auxiliary ruler 2 is unfolded, the control rod 4 can simultaneously fix the state of the auxiliary ruler 2, so that one side wall of the auxiliary ruler 2 is always flush with one side wall of the main ruler 1.

[0041] When detecting the flatness of the wall surface, the device is closely attached to the wall surface. The flatness is judged by observing the gaps between the main ruler 1 and the auxiliary ruler 2 and the wall surface. If there are uneven areas, they can be marked for subsequent repair. This leveling rule is flexible and convenient to operate, and has a reasonable structural design, which can improve the efficiency and accuracy of wall surface flatness detection in building construction and provide a strong guarantee for the construction quality.

[0042] The above are only the preferred embodiments of the utility model, and are not intended to limit the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included within the protection scope of the utility model.
