[0002] With the development of science and technology, civil engineering construction technology has also gradually developed. In the field of engineering construction, in order to ensure the flatness of the wall, it is necessary to conduct a flatness test after the wall is constructed. Generally, the flatness detection of the wall requires the use of measuring tools such as a level or a level ruler. When using it, it is necessary to manually lean the measuring tool against the wall. When there is a pit, it is necessary to determine whether the pit meets the qualified standard by visual inspection or with a ruler. When there is a protrusion, the measuring tool cannot remain horizontal. Therefore, when it does not meet the qualified standard, the unqualified part is tested. This process is not convenient for marking the unqualified part, and it is not convenient to record the starting point of the test, which easily leads to repeated detection positions. In addition, since the measuring tool is not convenient to move, it is necessary to take the measuring tool to another part of the wall after one test to perform a flatness test. Repeated measurements and comparisons can measure the flatness of the wall. When facing a large wall, it takes a lot of time and manpower to test, and the efficiency of building detection is low.

The outer surface of the detection seat 4 is rotatably connected with a roller 12 for sliding on the wall;

[0034] The first driving assembly 7 includes a driving bar 71 fixedly arranged on the top wall of the detection slot 2, a sliding slot 72 for the driving bar 71 to slide is provided on the top of the detection seat 4, a first transmission slot 73 is provided inside the detection seat 4, a first transmission rod 74 is rotatably provided inside the first transmission slot 73, the bottom of the driving bar 71 abuts against the top of the first transmission rod 74, a pressing plate 76 is elastically connected to the inner side of the first mounting seat 5 through a second spring 75, the outer surface of the pressing plate 76 abuts against the bottom of the first transmission rod 74, a first protrusion 77 is fixedly provided on the top of the first mounting seat 5, a first groove 78 is provided inside the detection seat 4, and the first protrusion 77 is elastically arranged in the first groove 78 through a third spring 79;

[0035] The second driving assembly 10 includes a second transmission groove 101 opened inside the detection seat 4, a second protrusion 102 is fixedly arranged on one side of the second mounting seat 8, a second groove 103 is opened inside the detection seat 4, the second protrusion 102 is elastically arranged in the second groove 103 by a fourth spring 104, a second transmission rod 105 and a third transmission rod 106 are rotatably connected in the second transmission groove 101, the second transmission rod 105 and the third transmission rod 106 are transmission-connected by two sets of U-shaped rings 107, and an end of the first abutting rod 11 is arranged on one side of the third transmission rod 106 for driving the third transmission rod 106 to rotate;

[0036] In the present technical solution, when the flatness of a wall is detected, first, when horizontal movement detection is required, the detection ruler body 1 is placed vertically and moved horizontally along the wall; when vertical movement detection is required, the detection ruler body 1 is placed horizontally and moved vertically along the wall; specifically, before the detection, the first marking pen 6 is inserted into the first mounting seat 5 with interference fit, the first spring 3 is in a pressure-free state, the first marking pen 6 is ejected to the farthest position, the first marking pen 6 first contacts the wall with the roller 12, and makes a marking point on the wall to mark the first detected position, so as to facilitate the worker to identify the first detected part and know the starting point of the detection more quickly;

[0037] Then, the detection ruler body 1 is pressed to move the detection seat 4 into the calibration groove, the first spring 3 accumulates force, and the force is released through the third spring 79, so that the first protrusion 77 is pulled to slide in the first groove 78, and the first protrusion 77 drives the first mounting seat 5 to move into the detection seat 4, and the first marking pen 6 is retracted; during the movement, if a certain degree of pit is encountered on the wall, the first spring 3 releases force, and the detection seat 4 is pushed out from the detection groove 2, and the first transmission rod 74 is abutted by the driving bar 71 to rotate the first transmission rod 74, and the other end of the first transmission rod 74 abuts the pressing plate 76, and the pressing plate 76 accumulates force through the second spring 75 to push the first mounting seat 5 to move, and at the same time stretches the third spring 79 to push the first mounting seat 5 out, and the first marking pen 6 marks the pit. When the wall is flat again, the first spring 3 is compressed, the second spring 75 and the third spring 79 release force, and the first marking pen 6 and the first mounting seat 5 return to the detection seat 4 again, completing the detection when the wall has a certain degree of pit;

[0038] The second marking pen 9 and the first marking pen 6 can be crayons, pencils, etc. The second marking pen 9 and the first marking pen 6 have different colors for easy distinction. When encountering a protruding part of the wall, the detection seat 4 slides into the detection groove 2, the first spring 3 is compressed, and the first marking pen 6 shrinks into the detection seat 4. At this time, the first abutting rod 11 abuts against one end of the third transmission rod 106. Figure 6 and Fig. 9 As shown, when the protruding position is unqualified, the detection seat 4 continues to slide in the detection groove 2, and the first resistance rod 11 applies a thrust to the third transmission rod 106, and the third transmission rod 106 rotates. At the same time, the other end of the third transmission rod 106 drives the second transmission rod 105 to rotate through two sets of U-shaped rings 107, so that the other end of the second transmission rod 105 pushes the second mounting seat 8, and pushes the second mounting seat 8 out from one side of the detection seat 4, and the protruding part is marked and marked by the second marking pen 9, so as to complete the flatness detection of the protruding part of the wall;

[0039] During this detection process, the pits and protrusions of the wall can be detected simultaneously while the detection ruler body 1 is moving. There is no need for workers to visually judge the eligibility of the pits and protrusions of the wall, thereby increasing the detection rate. During the detection process, it is only necessary to slide the detection ruler body 1 and mark with the first marking pen 6 and the second marking pen 9. This not only increases the adequacy of wall detection, but also facilitates marking of walls and protrusions with a certain degree of pits, so that workers can accurately locate the marked parts after the detection. In addition, by using the first marking pen 6 and the second marking pen 9 of different colors, it is possible to quickly distinguish whether the marked position is a pit or a protrusion.

[0040] In order to increase the detection accuracy of the first marking pen 6, the first transmission rod 74 is rotatably arranged in the first transmission groove 73 through the first pin shaft 710, and the first pin shaft 710 is arranged at the upper part of the first transmission rod 74, and the first transmission rod 74 is divided into a short upper part and a long lower part by the first pin shaft 710. Figure 4 , so that the distance that the first mounting seat 5 moves in the detection seat 4 is much greater than the distance that the driving bar 71 moves relative to the upper part of the first transmission rod 74, thereby facilitating the first mounting seat 5 to slide out from the inside of the detection seat 4, thereby increasing the detection accuracy;

[0041] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figure 1-Figure 11 The first mounting seat 5 is rotatably connected to the detection seat 4 through a rotating assembly 13, the rotating assembly 13 includes a rotating shaft 131, the end of the rotating shaft 131 is provided with a positioning block 136 for fixing the first marking pen 6, the rotating shaft 131 is elastically connected to the detection seat 4 through a torsion spring 132, the positioning block 136 is rotatably arranged in the first mounting seat 5, a rotating disk 133 is fixed to the end of the rotating shaft 131 away from the first mounting seat 5, a wedge block 134 is eccentrically arranged on the outer surface of the rotating disk 133, and a push rod 135 that can contact the wedge block 134 is fixed on the inner surface of the pressing plate 76;

[0042] A third mounting seat 14 is slidably connected inside the detection seat 4, and a third marking pen 15 is installed on the third mounting seat 14. A third driving assembly 16 having the same structure as the second driving assembly 10 is also provided inside the detection seat 4, and the third driving assembly 16 is drivingly connected to the third mounting seat 14. A second interference rod 17 for abutting against the third driving assembly 16 is provided on the inner wall of the detection slot 2. The second interference rod 17 pushes the third marking pen 15 out by abutting against the third driving assembly 16, and the length of the second interference rod 17 is less than the length of the first interference rod 11;

[0043] In the present technical solution, the third marking pen 15 can be a crayon, a pencil, etc. When a deeper pit is detected on the wall, the first spring 3 continues to release force, and the detection seat 4 continues to be pushed out of the detection slot 2. The first transmission rod 74 continues to apply pressure to the pressure plate 76, and the pressure plate 76 drives the push rod 135 to move, so that the end of the push rod 135 contacts the wedge block 134, and a cross-sectional force is applied to the wedge block 134, so that the turntable 133 drives the rotating shaft 131 to rotate a certain angle, and the torsion spring 132 accumulates force, and the rotating shaft 131 rotates a certain angle. Driven by the rotating shaft 131, the positioning block 136 drives the first marking pen 6 to rotate a certain angle, so that the first marking pen 6 can draw a wider marking line, thereby marking the deeper pit, which is convenient for distinguishing it from ordinary pits, and convenient for workers to determine the condition of the pit on the wall according to the width of the marking line;

[0044] When it is detected that the wall has a higher protruding part, while the first abutting rod 11 pushes out the second mounting seat 8, the second abutting rod 17 abuts against the third driving assembly 16, so that the third driving assembly 16 pushes the third mounting seat 14 out of the side of the detection seat 4. The third driving assembly 16 has the same structure as the second driving assembly 10. The specific working principle refers to the second driving assembly 10 part mentioned above. The second marking pen 9 and the third marking pen 15 are used to mark the higher protruding part at the same time to complete the marking process at the higher protruding part of the wall. The difference in the number of two lines and one line makes it easy to distinguish between the higher protruding part and the ordinary protruding part, so as to determine the condition of the protruding part of the wall.

[0045] In order to prevent the two groups of U-shaped rings 107 from being pulled apart, the two groups of U-shaped rings 107 are elastically connected by a fifth spring 108, and the ends of the second transmission rod 105 and the third transmission rod 106 are both against the inner side of the U-shaped ring 107; by providing the fifth spring 108, the two groups of U-shaped rings 107 will not be pulled apart when subjected to excessive tension, thereby playing a protective role;

[0046] In order to increase the accuracy of the third marking pen 15 and the detection of the third marking pen 15, the second transmission rod 105 is rotatably arranged in the second transmission groove 101 through the second pin shaft 109, and the second pin shaft 109 is arranged at one end of the second transmission rod 105 close to the U-shaped ring 107, and the third transmission rod 106 is rotatably arranged in the second transmission groove 101 through the third pin shaft 110, and the third pin shaft 110 is arranged at one end of the third transmission rod 106 away from the U-shaped ring 107. The second rotating rod is divided into a short upper part and a long lower part by the second pin shaft 109, and the third rotating rod is divided into a short upper part and a long lower part by the third pin shaft 110. Figure 8, so that the distance that the second mounting seat 8 and the third mounting seat 14 move in the detection seat 4 is much greater than the distance that the detection seat 4 moves relative to the detection slot 2, thereby facilitating the second mounting seat 8 and the third mounting seat 14 to slide out from the inside of the detection seat 4, thereby increasing the accuracy of the detection;

[0047] In order to prevent the acting force between the first resistance rod 11 and the third transmission rod 106 from being too large, causing the first resistance rod 11 to be broken due to the resistance, the end of the first resistance rod 11 away from the third transmission rod 106 is slidably sleeved with a sleeve 111, and the end of the first resistance rod 11 is slidably arranged in the sleeve 111 through a sixth spring 112; the set sixth spring 112 can make the first resistance rod 11 slide in the sleeve 111, thereby preventing the first resistance rod 11 from being broken due to excessive force.

[0048] Embodiment 3: This embodiment is an improvement made on the basis of Embodiment 2. For details, please refer to Figure 1-Figure 11 Both ends of the detection ruler body 1 are provided with a wall stability detection mechanism 18, and the wall stability detection mechanism 18 includes a storage groove 181, and a rotating rod 182 is fixedly provided in the storage groove 181, and a tape roll 183 is rotatably sleeved on the circumference of the rotating rod 182, and a limiting component 184 is provided on the rotating rod 182 to prevent the tape roll 183 from sliding off the end of the rotating rod 182, and a compacting roller 185 for pressing the tape against the wall is rotatably provided on the outer side of the storage groove 181;

[0049] In the present technical solution, when the detection ruler body 1 detects the flatness of the wall, one end of the tape is pre-bonded to the wall, and the outer surface of the tape is pressed by the compacting roller 185. When the detection ruler body 1 moves, the provided tape roll 183 rotates on the rotating rod 182 inside the storage slot 181, and the compacting roller 185 presses the tape tightly against the surface of the wall. After the movement is completed, the tape is cut by a cutter, and after waiting for a period of time, the tape is torn off the wall to observe whether the wall is torn. In this way, the flatness of the wall can be detected while the stability of the wall is detected. In addition, the limiting component 184 can limit the rotation of the tape roll 183 in the storage slot 181, and the limiting component 184 can be a nut threadedly connected to the end of the rotating rod 182, which is easy to disassemble, thereby completing the replacement of the tape roll 183.
