[0003] Traditional straightedges come in 1-meter and 2-meter sizes, with a folded length of 1 meter and an unfolded length of 2 meters. They are stored by folding to ensure the integrity of both sides. However, after folding and unfolding, traditional straightedges are prone to issues with whether the two sides are on the same horizontal plane, which can be attributed to the stability problem of the hinge. In addition, the function of traditional straightedges is relatively simple, relying only on the ruler plate for basic measurements. When inspecting building walls, it is necessary to test multiple indicators of the wall, requiring the use of different tools. This means that multiple traditional single-function testing devices need to be prepared, causing inconvenience in carrying the equipment. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-7 As shown, this utility model provides a liftable non-destructive testing device for building walls, including a straightedge main structure. The straightedge main structure includes a telescopic part 1 in the middle and fixed blocks 2 at both ends. The telescopic part 1 includes an outer frame 101 and an inner rod 102. The inner rod 102 is slidably disposed in the inner cavity of the outer frame 101. The fixed blocks 2 are respectively fixed to one end of the inner rod 102 and the outer frame 101. The outer frame 101 is provided with a drive assembly 3 for telescopic adjustment of the inner rod 102. A spirit level 4 is installed on the fixed blocks 2.

[0029] The inner ruler rod 102 is driven by the drive component 3, which allows the inner ruler rod 102 to extend and retract within the inner cavity of the outer ruler frame 101, adjusting the length of the main body of the ruler. Simultaneously, the inner ruler rod 102 slides within the inner cavity of the outer ruler frame 101, enabling smooth movement of the inner ruler rod 102 and one side of the outer ruler frame 101 to ensure the level of the measuring surface. Additionally, bubble levels 4 are installed at both ends of the main body of the ruler for level detection under different measuring environments. Furthermore, a right-angle ruler 12 is provided for right-angle measurement of the corners of building walls, demonstrating the multi-functionality of the ruler and reducing the carrying weight of single-function measuring tools.

[0030] Among them, such as Figure 3 As shown:

[0031] The drive assembly 3 includes a drive motor 31 fixed to one end of the inner cavity of the outer scale frame 101. A ball screw 32 is fixed to the output shaft of the drive motor 31. A connecting block 34 is threadedly connected to the outer side of the ball screw 32 through a screw pair 33. One side of the connecting block 34 is fixed to the side wall of the inner scale rod 102. The drive motor 31 drives the ball screw 32 to rotate, and then the screw pair 33 moves the connecting block 34 to translate. The connecting block 34 drives the inner scale rod 102 to extend and retract within the outer scale frame 101.

[0032] like Figure 5-7 As shown, mounting bases 5 are fixedly embedded on the end and side wall of the fixed block 2. A movable seat 6 is movably arranged in the inner cavity of the mounting base 5. The level bubble 4 is fixedly installed on the inner side of the movable seat 6. An adjustment component 7 for rotating the mounting base 5 by 90 degrees is provided in the mounting base 5. The angle of the level bubble 4 can be adjusted by rotating the movable seat 6 in the mounting base 5. The movable seat 6 can be rotated by 90 degrees by adjusting the component 7.

[0033] like Figure 6-7 As shown, the adjustment assembly 7 includes a movable groove 71 formed around the outer perimeter of the movable seat 6. A support spring 72 is fixed inside the movable groove 71. A support base 73 is fixed to one end of the support spring 72. The end of the support base 73 away from the support spring 72 extends outward and abuts against a steel ball 74. Positioning holes 75 that cooperate with the steel ball 74 are formed around the perimeter of the inner cavity of the mounting base 5. The steel ball 74 is supported by the support spring 72 and the support base 73, allowing the steel ball 74 to extend and retract within the movable groove 71, facilitating engagement with the positioning holes 75. This enables the movable seat 6 to be angle-limited, allowing it to rotate 90 degrees. The levelness is then checked using a bubble level 4.

[0034] It is worth noting that, such as Figure 4 As shown:

[0035] The connecting block 34 has a through groove inside, and a flexible protective plate 8 is movably installed in the inner cavity of the through groove. The two ends of the flexible protective plate 8 extend to the outside of the through groove and are fixed to the two ends of the inner cavity of the outer frame 101. The flexible protective plate 8 facilitates the isolation of the inner cavity space of the outer frame 101, and facilitates the protection of the ball screw 32, preventing external dust and sand from falling between the ball screw 32 and the screw pair 33, thus accelerating the wear of the ball screw 32.

[0036] In a further preferred embodiment, such as Figure 2 As shown:

[0037] One side of the inner ruler rod 102 is flush with one side of the outer ruler frame 101. A groove 9 is provided at the center of one side of the inner ruler rod 102. A limiting rod 10 is slidably arranged in the inner cavity of the groove 9. One end of the limiting rod 10 is fixed on a set of fixing blocks 2. By setting the limiting rod 10, not only can the flatness of the detection surface of the outer ruler frame 101 be ensured, but the inner ruler rod 102 can also be limited, so that the inner ruler rod 102 and the outer ruler frame 101 remain stable and the detection surfaces of the inner ruler rod 102 and the outer ruler frame 101 remain smooth.

[0038] In addition, such as Figure 5 As shown:

[0039] The fixed block 2 has slots 11 on both sides of its ends. A right angle ruler 12 is hinged to the inner cavity of the slot 11. A through hole 13 is opened on the outer side of the fixed block 2. A positioning bolt 14 is movably installed in the inner cavity of the through hole 13. A threaded hole 15 is opened on the right angle ruler 12 to be threadedly connected to the positioning bolt 14. By hinged to the right angle ruler 12 in the slot 11, the right angle ruler 12 can be moved out to inspect the corner of the building wall.

[0040] In practical use, when it is necessary to use a straightedge to check the flatness of a building wall, the drive motor 31 is started. The drive motor 31 drives the ball screw 32 to rotate. The ball screw 32 moves the connecting block 34 through the screw pair 33. Then, the connecting block 34 drives the inner ruler rod 102 to slide inside the outer ruler frame 101, increasing the length of the telescopic part 1. At the same time, the inner ruler rod 102 and the detection surface of the outer ruler frame 101 remain smooth. The unfolded straightedge main structure is placed against the outside of the building wall, which can directly detect the flatness of the wall. At the same time, the straightedge main structure is placed on a horizontal wall. On the body, the horizontality of the wall is checked by the level bubble 4 at the top, and then the movable seat 6 is rotated. Through the rotation of the movable seat 6, the steel ball 74 is squeezed and retracted into the moving groove 71. After the steel ball 74 is aligned with the next set of positioning holes 75, a 90-degree rotation is achieved. The horizontality is checked again by the level bubble 4 to ensure the accuracy of the test. When it is necessary to check the verticality of the wall, the unfolded straightedge main structure is first placed against the outside of the wall, and then the horizontality of the top of the fixed block 2 is checked by the level bubble 4 at the top, thus indirectly checking the verticality of the wall.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
