[0027] As Figures 1-5 The utility model provides a kind of wall flatness detection rest ruler for construction engineering, including connecting plate main body 1, the outer side wall of connecting plate main body 1 is symmetrically rotated sleeve joint with two side rest rulers 2, two side rest rulers 2 and connecting plate main body 1 are limited annularly by being provided with positioning pin 8, the lower portion of each side rest ruler 2 is provided with the protection mechanism 6 of preventing side rest ruler 2 and contact surface from being abraded, side rest ruler 2 and protection mechanism 6 are provided with the limiting mechanism 7 that both are quickly separated between them.

[0028] It should be noted that the symmetrical rotating sleeve is connected to the two side leaning rulers 2 on the outer side wall of the connecting plate body 1, and is annularly limited by the positioning pin 8, so that the side leaning ruler 2 can be flexibly rotated and adjusted in angle to adapt to different wall detection requirements, and the positioning pin 8 ensures the stability after adjustment, so that the detection process is more accurate and reliable. The protection mechanism 6 arranged below each side leaning ruler 2 effectively prevents the side leaning ruler 2 from being worn with the contact surface, prolongs the service life of the side leaning ruler 2, and reduces the equipment maintenance cost. At the same time, the protection mechanism 6 can also reduce the detection error caused by wear, and ensure the accuracy of the detection data. When the protection mechanism 6 is damaged or needs to be replaced with a protection piece of different material, the construction personnel can quickly complete the operation, save time and effort, and improve work efficiency.

[0029] As shown in Figure 1 and Figure 2 , the protection mechanism 6 includes a protection frame 61 arranged below the side leaning ruler 2, and the inner side wall of the protection frame 61 is fixedly connected with two fixed shafts 62 symmetrically, and the inner side wall of the protection frame 61 is provided with six limiting holes 63 between the two fixed shafts 62.

[0030] It should be noted that the protection frame 61 is arranged below the side leaning ruler 2, which provides a stable support foundation for the entire protection structure, can effectively disperse the pressure generated when the side leaning ruler 2 contacts with the contact surface, and avoid damage caused by excessive local stress.

[0031] As shown in Figures 2-5 , each set of limiting mechanism 7 includes an elastic sleeve frame 71 fixedly connected to the lower bottom end of the side leaning ruler 2 symmetrically, and four fixed rods 76 are fixedly connected to the lower bottom end of the side leaning ruler 2 between the two elastic sleeve frames 71, and a fixed plate 73 is fixedly connected to the lower bottom end of the four fixed rods 76, and an extrusion plate 72 is slidably sleeved on the outer wall of the four fixed rods 76, and the contact surface between the extrusion plate 72 and the fixed rod 76 is provided with a through hole 721.

[0032] It should be noted that when the protection mechanism 6 is installed or disassembled, the elastic sleeve frame 71 can be clamped or separated with the fixed shaft 62 through its elastic deformation, which greatly improves the operation efficiency and saves the construction time. When the protection mechanism 6 needs to be limited and fixed, the extrusion plate 72 slides along the fixed rod 76 and extrudes the protection mechanism 6, which is firmly fixed in the appropriate position through the cooperation with the elastic sleeve frame 71, preventing it from loosening during the detection process, and ensuring the accuracy and stability of the detection. The through hole 721 provided on the extrusion plate 72 enables it to smoothly slide on the fixed rod 76, reducing the friction resistance and making the operation more labor-saving.

[0033] As shown in Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the upper end of each side rest ruler 2 is threadedly sleeved with a threaded screw rod 75, the inside of the extrusion plate 72 is embedded with a bearing 751, the end of the threaded screw rod 75 is fixedly connected to the inner ring of the bearing 751, the threaded screw rod 75 is rotationally sleeved with the extrusion plate 72 through the bearing 751, the outer wall of the fixed plate 73 is fixedly connected with three guide shafts 731 on both sides, two inclined blocks 74 are symmetrically arranged below the side rest ruler 2, three guide holes 741 that are sleeved with the guide shafts 731 are formed in the opposite side of the two inclined blocks 74, three limiting blocks 742 that are inserted into the limiting hole 63 are fixedly connected to the side away from each other of the two inclined blocks 74, the two sides of the extrusion plate 72 are movably abutted with the two inclined blocks 74, and the opposite side of the two inclined blocks 74 is magnetically connected.

[0034] It should be noted that the threaded screw rod 75 threadedly sleeved on the upper end of the side rest ruler 2 cooperates with the bearing 751 embedded in the inside of the extrusion plate 72, the construction personnel can easily drive the extrusion plate 72 to move up and down along the fixed rod 76 by rotating the threaded screw rod 75, the operation is simple and accurate, the extrusion force of the protection mechanism 6 can be flexibly adjusted, the limiting is firm and will not be damaged by excessive extrusion, the three guide shafts 731 fixed on the outer wall of the fixed plate 73 on both sides are sleeved with the guide holes 741 on the inclined blocks 74, which provides stable guidance for the movement of the inclined blocks 74, so that the movement track is accurate, and the stability and reliability of the limiting mechanism 7 are ensured, the opposite side of the two inclined blocks 74 is magnetically connected, which enhances the connection tightness between the two, and facilitates quick separation when needed, the limiting blocks 742 on the side away from each other of the inclined blocks 74 are inserted into the limiting hole 63, which realizes accurate limiting of the protection mechanism 6, and the two sides of the extrusion plate 72 are movably abutted with the two inclined blocks 74, when the extrusion plate 72 moves, it can push the inclined blocks 74 to move along the guide shafts 731, and then the limiting blocks 742 are inserted into or withdrawn from the limiting hole 63, realizing quick fixing and separation of the protection mechanism 6, improving the construction efficiency, and ensuring the smooth progress of the detection work.

[0035] As shown in Figure 1 and Figure 4 , the upper end of each side rest ruler 2 is threadedly sleeved with a threaded screw rod 75, the inside of the extrusion plate 72 is embedded with a bearing 751, the end of the threaded screw rod 75 is fixedly connected to the inner ring of the bearing 751, the threaded screw rod 75 is rotationally sleeved with the extrusion plate 72 through the bearing 751, the outer wall of the fixed plate 73 is fixedly connected with three guide shafts 731 on both sides, two inclined blocks 74 are symmetrically arranged below the side rest ruler 2, three guide holes 741 that are sleeved with the guide shafts 731 are formed in the opposite side of the two inclined blocks 74, three limiting blocks 742 that are inserted into the limiting hole 63 are fixedly connected to the side away from each other of the two inclined blocks 74, the two sides of the extrusion plate 72 are movably abutted with the two inclined blocks 74, and the opposite side of the two inclined blocks 74 is magnetically connected.

[0036] It should be noted that the guide groove 3 opened on the top end of the connecting plate body 1 and the two side leaning rulers 2 provides a track for the movement of the synchronous block 4, so that the synchronous block 4 can slide along the guide groove 3 to realize precise guidance and ensure the stability of the movement track of the synchronous block 4, so as to ensure the accuracy of the operation. The synchronous block 4 located inside the guide groove 3 on the top end of the connecting plate body 1 is slidably connected with the end surface of the guide groove 3 on the side leaning ruler 2 through magnetic attraction. This magnetic attraction connection method is simple and reliable. It can quickly and synchronously connect the two side leaning rulers 2 with the connecting plate body 1 when needed, so that the three form a stable overall structure, ensuring the stability and consistency of the ruler during detection and improving the detection accuracy. When it is necessary to adjust the angle of the side leaning ruler 2 or perform other operations, the synchronous block 4 can be easily separated from the side leaning ruler 2, which is convenient and efficient.

[0037] Working principle: In the use process, the protection mechanism 6 plays a key protection role. The protection frame 61 is located below the side leaning ruler 2. When the side leaning ruler 2 contacts the wall surface for detection, the protection frame 61 directly contacts the wall surface, avoiding direct friction between the side leaning ruler 2 and the wall surface, effectively preventing the wear of the contact surface between the side leaning ruler 2 and the wall surface due to long-time friction, and further avoiding the occurrence of detection errors, thereby ensuring the detection accuracy. At the same time, the two side leaning rulers 2 are symmetrically rotatably connected to the outer side wall of the connecting plate body 1 and are annularly limited by the positioning pin 8. When storage is needed, the angle of the two side leaning rulers 2 can be flexibly adjusted to make them close to each other, thereby achieving portable storage.

[0038] After long-term use, the end surface of the protection mechanism 6 will be worn. At this time, the limiting mechanism 7 plays a role. The threaded screw 75 is rotatably connected to the extrusion plate 72 through the bearing 751. The extrusion plate 72 will slide upward along the four fixed rods 76. The two inclined blocks 74 on both sides of the extrusion plate 72 are in movable abutment. With the upward movement of the extrusion plate 72, the extrusion force on the inclined blocks 74 disappears. The two inclined blocks 74 approach each other under the guidance of the magnetic attraction force and the guidance of the guide shaft 731 and the guide hole 741. The limiting block 742 exits from the limiting hole 63 in the inner side wall of the protection frame 61, thereby quickly realizing the separation of the side leaning ruler 2 and the protection frame 61, facilitating the replacement of the worn protection frame 61, and ensuring the normal use of the protection mechanism 6, thereby ensuring the continuous and efficient detection work.

[0039] During the detection process, the worker can observe the contact surface between the protection frame 61 and the wall surface. If the contact surface between the protection frame 61 and the wall surface is concave or convex, the flatness of the wall surface is not enough.

Any skilled person in the art, according to the technical scheme and improvement concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the scope of protection of the present application.
