While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0029] like Figures 1 to 3As shown, an embodiment of this utility model provides a wall flatness testing ruler, comprising: a ruler 1, a verticality testing instrument 2 fixedly connected to the surface of the ruler 1, a horizontality testing instrument 3 fixedly connected to the surface of the ruler 1, two connecting frames 4 fixedly connected to the side wall of the ruler 1, a disc 5 slidably connected to the inner wall of each of the two connecting frames 4, a round rod 6 fixedly connected to the surface of the disc 5, a pressing rod 10 slidably connected to the surface of each of the two connecting frames 4, a connecting plate 9 fixedly connected to the surface of the pressing rod 10, the pressing rod 10 and the round rod 6 slidably connected, an extension plate 12 fixedly connected to the surface of the connecting plate 9, and a scale groove 13 formed on the surface of the extension plate 12. When one side of the ruler 1 is pressed against the wall, the flatness can be tested, and then the ruler can be slidably pressed against the wall. The rod 10 moves to a new position, causing the extension plate 12 to slide towards the ruler 1. The operator can then determine the length of the gap by observing the distance from the graduated groove 13. A spring 18 is fitted onto the surface of the round rod 6, with both ends of the spring 18 fixedly connected to the disc 5 and the connecting plate 9, respectively. The spring 18 allows the rod 10 to press firmly against the wall surface, eliminating the need for manual operation and improving the convenience of flatness testing. A ball bearing 11 is rotatably connected to the end of the rod 10 furthest from the connecting plate 9. The ball bearing 11 improves the smoothness of the rod's movement on the wall, preventing jamming and allowing for rapid movement to the required testing position and quick understanding of the test results. A rotating... Both sides of the rotating plate 14 are fixedly connected to pressing blocks 15. The pressing blocks 15 are made of rubber and have a trapezoidal cross-section. Rotating the rotating plate 14 allows one side of the pressing block 15 to press against the surface of the connecting frame 4. Since the pressing block 15 is made of rubber, it increases the friction between it and the connecting frame 4, thereby limiting the position of the pressing rod 10 and preventing it from slipping after moving to the detection position, thus ensuring the accuracy of the data after detection. A pull ring 16 is fixedly connected to the surface of the extension plate 12. A protective ring 17 is glued to the inner wall of the pull ring 16. The protective ring 17 is made of sponge. When moving the pressing rod 10 and the disc 5, a finger can be placed inside the pull ring 16 and then the pull ring 16 can be pulled. The movable pressure rod 10 and the disc 5 move in position. A protective ring 17 is located on the inner wall of the pull ring 16, improving the comfort of placing fingers inside the pull ring 16. Two auxiliary plates 7 are slidably connected to the surface of the ruler 1. Both auxiliary plates 7 are L-shaped. When measuring the vertical flatness of a wall, the operator can slide out the auxiliary plates 7 and place their foot on the protruding side, conveniently limiting the ruler 1 and preventing it from tilting without support. Two adhesive plates 8 are glued to the surface of the ruler 1. The surfaces of the adhesive plates 8 are covered with double-sided adhesive. When not in use, the auxiliary plates 7 can be slid towards the ruler 1, allowing them to adhere to the surface of the adhesive plates 8.It will not slip when carried or used.

[0030] In this embodiment of the utility model (working principle), the ruler 1 is folded or unfolded according to the wall surface, and then the ruler 1 is pressed against the wall surface. At this time, the operator can place their fingers inside the pull ring 16, which contacts the protective ring 17 on the inner wall of the pull ring 16. This can drive the extension plate 12 and the pressing rod 10 to move to the gap position that needs to be detected. When the pressing rod 10 slides, the roller will slide against the wall surface at the same time, reducing the friction of the pressing rod 10 itself and preventing the pressing rod 10 from being blocked when moving. Then the operator can further rotate the rotating plate 14, so that the pressing block 15 on one side of the rotating plate 14 presses against the surface of the connecting frame 4. The pressing block 15 increases the pressure on the wall surface. Friction prevents the pressure rod 10 and extension plate 12 from sliding. Since the pressure rod 10 is pushed against the wall by the spring 18, it can drive the connecting plate 9 to slide in the direction of the straightedge 1, thereby moving the extension plate 12. At this time, the operator can understand the length of the gap by the distance marked on the surface of the scale groove 13 and the distance it moves, and then record it. It can detect whether the flatness of the wall meets the standard. When testing the flatness of the wall vertically, the auxiliary plate 7 can be slid so that the operator's feet can step on the surface of the auxiliary plate 7, so that the operator does not need to use too much force to support the straightedge 1, which facilitates the use of the straightedge 1. When the auxiliary plate 7 is not in use, it can be limited by the adhesive plate 8.

[0031] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
