Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

[0033] Furthermore, the term "identical" and similar terms do not necessarily require that the components be absolutely identical; slight variations are permitted.

[0034] Example 1:

[0035] See also Figure 1-2The utility model provides a technical solution: a building inspection ruler for construction engineering inspection, comprising a ruler body 1, wherein the ruler body 1 is provided with a plurality of measuring components on the side of the ruler body 1, and the plurality of measuring components are fixed to the side of the ruler body 1 along the length direction of the ruler body 1; the measuring component comprises a shell 2 fixedly connected to the ruler body 1, a measuring part, a linkage part and a reading part are provided in the shell 2, and the measuring part and the reading part are both slidably connected to the shell 2 along the thickness direction of the ruler body 1, and the lower end of the measuring part and the upper end of the reading part respectively pass through the bottom and top of the shell 2 and protrude from the bottom and top surfaces of the ruler body 1, and the linkage part is provided between the reading part and the measuring part, and the linkage part is used to drive the reading part to move downward when the lower end of the measuring part is squeezed by the surface to be measured and pushed upward to slide.

[0036] The measuring part and the reading part are both slidably connected to the housing 2, and the two are arranged in parallel. The lower end of the measuring part and the upper end of the reading part pass through the housing 2 and protrude from the bottom and top surfaces of the ruler body 1 respectively.

[0037] The measuring part and the reading part are connected by a linkage part. When the measuring part or the reading part moves in the longitudinal direction, the linkage part drives the reading part or the measuring part to move in the opposite direction. That is, the position change between the lower end of the measuring part and the ruler body 1 is converted into the position change between the upper end of the reading part and the ruler body 1 through the linkage part.

[0038] In this solution, multiple measuring components are set along the length direction of the ruler body 1, that is, multiple measuring points can be formed along the length direction of the ruler body 1. By reading the position change between the reading part and the ruler body 1 at each measuring point, the height difference between the multiple points can be directly obtained.

[0039] Specifically, before measurement, the multiple measuring parts and the multiple reading parts are adjusted so that the lower ends of the multiple measuring parts are on the same straight line and parallel to the bottom surface of the ruler body 1, and the upper ends of the multiple reading parts are on the same straight line and parallel to the top surface of the ruler body 1;

[0040] Then, place the ruler 1 with its bottom side facing downward on the ground to be measured. The ruler 1 is then used to keep the multiple measuring parts in contact with the ground by its own weight or by applying pressure to the ruler 1. When the lower end of the measuring part is pressed upward in the housing 2, the reading part will move downward.

[0041] If the ground being measured is flat and the moving distances of the multiple measuring units are the same, the moving distances of the multiple reading units are also the same;

[0042] If there is a local depression in the ground being measured, the distance the measuring part opposite to the depression moves upward is relatively small, and the distance the corresponding reading part moves downward is also small, forming a convex point on the straight line formed by multiple measuring parts;

[0043] Conversely, if the measured ground exists local convex, then the measuring part opposite to the convex moves upward with relatively large distance, then the corresponding reading part moves downward with relatively large distance, and the concave point will be formed on the straight line constituted by the plurality of measuring parts;

[0044] The unevenness can be intuitively identified, and the specific difference can be obtained by comparing the distance change value between the concave or convex point and other positions, which is used for calculating the unevenness.

[0045] In the embodiment, the measuring part comprises a measuring rack 4 and a measuring rod 7 connected with the lower end of the measuring rack 4, the measuring rod 7 is parallel to the measuring rack 4, and the lower end extends downward through the housing 2 and protrudes from the bottom surface of the ruler body;

[0046] The linkage part comprises an intermediate gear 5 which is rotatably connected in the housing 2 through a gear shaft 6;

[0047] The reading part comprises a reading rack 3, the upper end of the reading rack 3 extends through the housing 2 and protrudes from the top surface of the ruler body 1;

[0048] The reading rack 3 and the measuring rack 4 are arranged in parallel and are respectively engaged on both sides of the intermediate gear 5, the length direction extension lines of the reading rack 3 and the measuring rack 4 are perpendicular to the length direction extension line of the ruler body 1, and both are slidably connected with the housing in the thickness direction of the ruler body;

[0049] A supporting spring 8 is arranged between the upper end of the measuring rack 4 and the inner wall of the housing 2, the two ends of the supporting spring 8 respectively abut against the inner wall of the housing 2 and the upper end of the measuring rack 4, and under the supporting action of the supporting spring 8, the lower end of the measuring rack 4 keeps abutting against the inner wall of the housing 2.

[0050] The lower end of the measuring rod 7 extends downward through the housing 2, the extension direction is parallel to the sliding direction of the measuring rack 4, and the lower end of the measuring rod 7 protrudes from the bottom surface of the ruler body 1, which is equivalent to reserving a certain measuring space;

[0051] The upper end of the measuring rod 7 penetrates into the lower end of the measuring rack 4, the upper end of the measuring rack 4 is connected with the inner wall of the housing 2 through the supporting spring 8, the axis direction of the supporting spring 8 is parallel to the sliding direction of the measuring rack 4, and under the action of the supporting spring 8, the measuring rack 4 keeps abutting against the inner wall of the housing 2 when not subjected to external force;

[0052] The intermediate gear 5 can rotate clockwise or counterclockwise relative to the housing 2 through the gear shaft 6 installed on the housing 2, the measuring rack 4 and the reading rack 3 are respectively engaged on both sides of the intermediate gear 5, and the sliding directions of the two racks are parallel;

[0053] The upper end of the reading rack 3 extends out of the housing 2 and protrudes from the top surface of the ruler body 1, which is equivalent to reserving a certain reading space.

[0054] When in use, the multiple measuring rods 7 and the multiple reading racks 3 are first adjusted so that the lower ends of the multiple measuring rods 7 are located on the same straight line and parallel to the bottom surface of the ruler body 1, and the upper ends of the multiple reading racks 3 are located on the same straight line and parallel to the top surface of the ruler body 1;

[0055] The lower end of the measuring rod 7 is squeezed by the surface to be measured, driving the measuring rack 4 to slide upward, further driving the intermediate gear 5 meshing with the measuring rack 4 to rotate counterclockwise, and the intermediate gear 5 drives the reading rack 3 to slide downward. The position change between the upper end of the reading rack 3 and the ruler body 1 can reflect the position change between the lower end of the measuring rod 7 and the ruler body 1, making it easier for the user to observe the unevenness of the surface to be measured;

[0056] In addition, when the measuring rack 4 slides upward in a direction parallel to the thickness of the ruler body 1, the support spring 8 is further compressed and maintains this state during the measurement process. When the measurement is completed, the interference between the measuring rod 7 and the measured surface is released. Under the action of the support spring 8, the measuring rack 4 slides downward relative to the thickness direction of the ruler body 1 and resumes the interference with the inner wall of the housing 2. At the same time, it drives the intermediate gear 5 to rotate clockwise relative to the housing 2, further driving the reading rack 3 to slide upward and reset.

[0057] In this embodiment, an internal threaded hole is opened at the lower end of each measuring rack 4, and an external thread is opened at the upper end of each measuring rod 7. The extension direction of the thread axis is parallel to the measuring rack 4, the rotation directions of the internal and external threads match, and the upper end of the measuring rod 7 matches the shape of the internal space of the lower end of the measuring rack 4.

[0058] Specifically, when the measuring rod 7 is twisted, the housing 2 limits the rotation of the measuring rack 4 relative to the housing 2, so that the distance by which the lower end of the measuring rod 7 protrudes from the scale body 1 can be adjusted, and the parts of multiple measuring rods 7 that extend beyond the lower end of the scale body 1 can be adjusted to the same length. When the measuring rod 7 comes into contact with the surface to be measured, the thread can limit the up and down movement of the measuring rod 7 relative to the measuring rack 4, and then the position change between the lower end of the measuring rod 7 and the scale body 1 is converted into the position change between the upper end of the reading rack 3 and the scale body 1.

[0059] In this embodiment, a standard portion 17 is connected to one end of the ruler body 1. The bottom surface of the standard portion 17 is parallel to and lower than the bottom surface of the ruler body 1, and is higher than the lower end of the measuring portion.

[0060] The ruler body 1 is connected to the standard part 17. When the entire ground to be measured is uneven, using only the ruler body 1 as the detection standard will lead to inaccurate detection results. In this case, the bottom surface of the standard part 17 is used as the measurement standard. The bottom surface of the standard part 17 is parallel to and lower than the bottom surface of the ruler body 1, and can be placed directly on the ground. The bottom surface of the standard part 17 is higher than the lower end of the measuring part, preventing the measuring rod 7 from not contacting the ground to be measured during measurement.

[0061] In this embodiment, a level 16 is installed on the top surface of the standard part.

[0062] When it is necessary to check the inclination of the ground, place the measuring ruler on the ground to be measured, adjust the lower ends of the multiple measuring rods 7 to be in the same straight line and parallel to the bottom surface of the ruler body 1, and make the upper ends of the multiple reading racks in the same straight line, observe the level 16. When the bubble of the level 16 shows that the measuring ruler remains horizontal, use a pad to pad the end of the ruler body 1 away from the standard part 17 so that the standard part 17 and the ruler body 1 are in the same horizontal line;

[0063] If the ground being measured is horizontal, the straight line formed by the multiple measuring units and the straight line formed by the multiple reading units are both parallel to the horizontal line;

[0064] If the ground being measured is tilted at a certain angle to the horizontal line, the straight line formed by the multiple measuring parts will also form this tilt angle with the horizontal line, which can intuitively identify the degree of tilt of the ground being measured. The specific tilt angle can be calculated by combining the change in the distance between the upper end of any reading rack 3 and the ruler body 1 with the distance between the selected reading rack 3 and one end of the standard part 17.

[0065] Example 2:

[0066] See also Figure 3 、 Figure 4 The present invention also provides a technical solution, which is different from the first embodiment in that a single measuring component is slidably connected to the ruler body 1.

[0067] The detection component is slidably connected to the outside of the ruler body 1, and the measuring component is slidably connected to the side of the shell 2. The side of the ruler body 1 is provided with a first sliding groove 11 along the length direction of the ruler body 1. The first sliding groove 11 is slidably connected to the slider 12, and the shell 2 is fixedly connected to the slider 12.

[0068] When the housing 2 is moved, the housing 2 drives the slider 12 to make the measuring component slide along the first sliding groove 11 , that is, the ruler body 1 serves as the sliding track of the measuring component.

[0069] Specifically, before measurement, the measuring rod 7 and the reading rack 3 are adjusted so that the lower end of the measuring rod 7 is lower than the bottom surface of the ruler body 1 and can contact the surface to be measured, and the upper end of the reading rack 3 is located at a position protruding from the top surface of the ruler body 1;

[0070] If there are local unevenness on the ground being measured, the upward movement distance of the measuring rod 7 relative to the depression or convexity will be relatively small or large, and the corresponding downward movement distance of the reading rack 3 will also be small or large, forming convex points and concave points on the sliding track of the measuring rod 7; the unevenness can be identified intuitively, and the specific difference can be obtained by comparing the distance change value between the concave point or convex point and other positions, which is used to calculate the unevenness.

[0071] In addition, this embodiment can also be used to measure the inclination of the ground to be measured.

[0072] If the ground being measured is horizontal, the sliding track of the measuring component is parallel to the horizontal line;

[0073] If the ground being measured is tilted at a certain angle to the horizontal line, the sliding trajectory of the measuring assembly will also form this tilt angle with the horizontal line. The change in the distance between the upper end of the reading portion and the scale body 1 can intuitively identify the degree of tilt of the ground being measured. The specific tilt angle can be calculated by combining the change in the distance between the upper end of the reading rack 3 and the scale body 1 with the distance between the reading rack 3 and one end of the standard portion 17.

[0074] In this embodiment, an adsorption portion 15 is fixed to one end of the ruler body 1 . The adsorption portion 15 is arranged outside the connection end of the ruler body 1 and the standard portion 17 and cooperates with the housing 2 of the measuring assembly.

[0075] The adsorption part 15 and the shell 2 of the measuring component are preferably made of a combination of magnetic adsorption material and iron alloy material; by turning the shell 2, the connection state between the shell 2 and one end of the standard part 17 of the ruler body 1 can be controlled. When measurement is required, the connection state between the shell 2 and the ruler body 1 is released.

[0076] The adsorption portion 15 can also be a leather cup, and the end of the shell 2 opposite to it can be provided with a smooth plane opposite to the leather cup. When the detection ruler is carried in a non-use state, the leather cup is fastened, and the shell 2 is adsorbed on one end of the standard part 17 of the ruler body 1 under the action of atmospheric pressure.

[0077] In addition, the adsorption part 15 can also be replaced by a connecting part, which is composed of a first connecting part and a second connecting part. The first connecting part and the second connecting part are respectively installed on the shell 2 and the standard part 17 of the measuring component. The connection method of the first connecting part and the second connecting part can be Velcro, snap, hook, adhesion and other connection methods.

[0078] When not in use, the adsorption portion 15 or the connection portion is used to fix the measuring component to prevent the measuring component from sliding freely when the user is carrying it, reduce the collision between the measuring component and the ruler body 1, prevent the components inside the measuring component housing 2 from loosening from each other, and extend the service life.

[0079] Example 3:

[0080] See also Figure 5 The difference from the second embodiment is that the ruler body 1 has a hollow structure, the measuring assembly is slidably connected to the ruler body 1, the top and bottom surfaces of the ruler body 1 are provided with a second slide groove 9 and a third slide groove 10 along the length direction of the ruler body 1, the upper end of the reading rack 3 and the lower end of the measuring rod 7 extend out of the ruler body 1 through the second slide groove 9 and the third slide groove 10 respectively, and the adsorption portion 15 is provided inside the connection between the ruler body 1 and the standard portion 17.

[0081] When the measuring component slides inside the ruler body 1, the extension directions of the second slide groove 9 and the third slide groove 10 are parallel to the length direction of the ruler body 1, that is, the ruler body 1 serves as the sliding track of the measuring component, and the adsorption part 15 is also inside the ruler body 1 and can be in direct contact with the shell 2 to ensure the adsorption effect.

[0082] In this embodiment, a fourth sliding slot 14 extending along the length direction is formed on the side of the ruler body 1 , and a handle 13 is connected to the side of the housing 2 . The handle 13 passes through the fourth sliding slot 14 and extends laterally out of the ruler body 1 .

[0083] The extension direction of the fourth slot 14 is parallel to the length direction of the ruler body 1, that is, the ruler body 1 serves as the sliding track of the measuring assembly. The handle 13 can slide left and right in the fourth slot 14. When measurement is required, the handle 13 is toggled to release the connection between the housing 2 and one end of the standard portion 17 of the ruler body 1, allowing the measuring assembly to slide along the fourth slot 14, making operation more convenient. Then, the measuring rod 7 is used to detect the unevenness or inclination of the surface to be measured.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
