Description

Technical Field

[0001] This utility model relates to the field of engineering inspection rulers, and in particular to a multifunctional engineering inspection ruler. Background Technology

[0002] An engineering inspection ruler is a quality inspection tool specifically designed for various construction projects, including building construction, interior decoration, bridge construction, and equipment installation. Its main function is to ensure that the quality of the project meets standards during the construction and completion stages. It is particularly important for inspecting the verticality, horizontality, and flatness of buildings. In home renovation supervision, this tool is used very frequently. It can effectively inspect the flatness and verticality of walls and tiles, while also ensuring the levelness and flatness of floor joists.

[0003] Currently, commonly used engineering measuring rulers are integrated and relatively long, which makes them take up a lot of space when carried and stored, making them inconvenient to transport and store. Moreover, longer measuring rulers may be more susceptible to damage during use, and may be difficult to operate in narrow or restricted spaces, thus limiting their scope of application.

[0004] In response to the problem that the engineering inspection ruler is too long and inconvenient to fold, this application proposes a multifunctional engineering inspection ruler. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multifunctional engineering measuring ruler. This measuring ruler can be folded at any angle, resulting in a small size after folding, making it easy to carry and not taking up too much space. It is highly portable and can be unfolded or adjusted more flexibly to meet various complex measurement needs and improve the flexibility of use.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A multi-functional engineering inspection ruler, comprising:

[0008] A second measuring ruler, a second rotating block is fixedly connected to the left end of the second measuring ruler, a connecting block is connected to the inner wall of the second rotating block through an adjusting component, the outer wall of the connecting block is rotatably connected to the inner wall of the second rotating block, a first rotating block is connected to the bottom end of the second rotating block through a limiting component, the top end of the first rotating block is rotatably connected to the bottom end of the second rotating block, and a first measuring ruler is fixedly connected to the rear end of the outer wall of the first rotating block.

[0009] The first measuring ruler has a level on its inner wall, and the second measuring ruler has at least two hexagonal holes on the right side of its top. Both the first and second measuring rulers have length scales on their top inclined surfaces, and the second rotating block has an angle scale on its top.

[0010] Furthermore, the adjustment assembly includes a fixed ring fixedly connected to the inner wall of the second rotating block, long sliding grooves are provided on all four sides of the outer wall of the fixed ring, the top of the connecting block is slidably connected to the inner wall of the long sliding groove, and short sliding grooves are provided on all four sides of the bottom of the fixed ring.

[0011] Furthermore, an adjusting block is slidably connected to the inner wall of the fixed ring, and a squeezing roller is fixedly connected to the bottom of the four sides of the outer wall of the adjusting block, and the squeezing roller is embedded in the inner wall of the long sliding groove.

[0012] Furthermore, the limiting component includes a face gear rotatably connected to the bottom end of the connecting block, and the face gear is slidably connected to the inner wall of the first rotating block.

[0013] Furthermore, a spring is fixedly connected to the bottom end of the face gear, and the other end of the spring is fixedly connected to the bottom end of the inner wall of the first rotating block.

[0014] Furthermore, a toothed ring is fixedly connected to the inner wall of the bottom end of the second rotating block, and the bottom end of the toothed ring meshes with the top end of the face gear.

[0015] Furthermore, the first and second measuring rulers are made of steel to provide high strength for the hexagonal holes during use.

[0016] Furthermore, the length and angle scales are made of fluorescent ink so that they emit visible fluorescence in poor lighting conditions.

[0019] 2. In this utility model, multiple functions are provided on the two measuring rulers, so that multiple measurement tasks can be completed at one time in actual use, avoiding the need to frequently change measuring tools, reducing interruptions and waiting time in the measurement process, thereby improving the overall accuracy and efficiency of measurement.

[0026] 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.

[0027] Reference Figures 2-4This utility model provides an embodiment of a multifunctional engineering inspection ruler, comprising a second measuring ruler 2, a second rotating block 4 fixedly connected to the left end of the second measuring ruler 2, a connecting block 11 provided on the inner wall of the second rotating block 4, the outer wall of the connecting block 11 rotatably connected to the inner wall of the second rotating block 4, a first rotating block 3 provided at the bottom end of the second rotating block 4, the top end of the first rotating block 3 rotatably connected to the bottom end of the second rotating block 4, a first measuring ruler 1 fixedly connected to the rear end of the outer wall of the first rotating block 3, a fixing ring 8 fixedly connected to the inner wall of the second rotating block 4, and long sliding grooves 15 provided on all four sides of the outer wall of the fixing ring 8, with the top of the connecting block 11 having a long sliding groove 15. The moving connection is on the inner wall of the long slide groove 15. Short slide grooves 14 are provided on all four sides of the bottom end of the fixed ring 8. The inner wall of the fixed ring 8 is slidably connected to the adjusting block 9. The bottom of the four sides of the outer wall of the adjusting block 9 is fixedly connected to the squeezing roller 10. The squeezing roller 10 is embedded in the inner wall of the long slide groove 15. The bottom end of the connecting block 11 is rotatably connected to the face gear 12. The face gear 12 is slidably connected to the inner wall of the first rotating block 3. The bottom end of the face gear 12 is fixedly connected to the spring 7. The other end of the spring 7 is fixedly connected to the bottom end of the inner wall of the first rotating block 3. The inner wall of the bottom end of the second rotating block 4 is fixedly connected to the face tooth ring 13. The bottom end of the face tooth ring 13 meshes with the top end of the face gear 12.

[0028] Specifically, when the adjusting block 9 is pressed down, it will cause the squeezing roller 10 to squeeze the connecting block 11 downward. At this time, the connecting block 11 will be squeezed out of the inner wall of the long slide groove 15. Then, because the squeezing roller 10 will squeeze the inclined surface of the connecting block 11, the connecting block 11 will rotate and enter the short slide groove 14 along the transition inclined surface at the bottom of the fixing ring 8. The connecting block 11 will then open the face gear 12, thereby unlocking the meshing restriction relationship between the face gear 12 and the face gear ring 13, and thus enabling the angle between the first measuring ruler 1 and the second measuring ruler 2 to rotate.

[0029] Reference Figure 1 The first measuring ruler 1 has a level 5 installed on its inner wall. The second measuring ruler 2 has at least two hexagonal holes 6 on the right side of its top. Both the first measuring ruler 1 and the second measuring ruler 2 have length scales on their top inclined surfaces. The second rotating block 4 has an angle scale on its top. The first measuring ruler 1 and the second measuring ruler 2 are made of steel so that the hexagonal holes 6 can provide high strength during use. The length scale and the angle scale are made of fluorescent ink so that they can emit visible fluorescence in poor lighting conditions.

[0030] Specifically, the level 5 uses a bubble level, consisting of a transparent tube and a liquid containing bubbles. During testing, the position of the bubbles in the tube is observed to determine whether the plane is level. When the bubbles in the tube are in the center, the plane is level. To accommodate the large torque generated during use by the hexagonal hole 6, the first measuring ruler 1 and the second measuring ruler 2 are made of steel, ensuring that the wrench is not easily worn or deformed during use and can work stably for a long time in various environments. The angle scale line set on the top of the second rotating block 4 can display the rotation angle between the first measuring ruler 1 and the second measuring ruler 2, thereby enabling angle detection.

[0031] Working principle: When the first measuring ruler 1 and the second measuring ruler 2 are folded, the adjusting block 9 is pressed down. At this time, the adjusting block 9 will drive the pressing roller 10 to push the connecting block 11 downward. Then, the connecting block 11 will drive the face gear 12 to move downward and disengage from the teeth of the face gear ring 13. Then, the connecting block 11 will disengage from the long slide groove 15 and enter the short slide groove 14, thereby keeping the face gear 12 in engagement with the face gear ring 13. Then, the first measuring ruler 1 or the second measuring ruler 2 is rotated. At this time, the first measuring ruler 1 and the second measuring ruler 2 will drive the first rotating block 3 and the second rotating block 4 to rotate respectively. Then, the angle can be measured according to the angle scale line at the top of the second rotating block 4. When the first measuring ruler 1 and the second measuring ruler 2 are folded down, the angle can be measured. When the two measuring rulers 2 are in a straight line, the length can be measured. After adjustment according to the actual situation, press the adjusting block 9 again. The adjusting block 9 will push the connecting block 11 through the action of the squeezing roller 10. As a result, the connecting block 11 will disengage from the short slide groove 14 and enter the long slide groove 15. Then, the face gear 12 will descend under the reaction force of the spring 7 and re-engage on the face gear ring 13. At this time, the first measuring ruler 1 and the second measuring ruler 2 will be restricted again. Measurement is then performed. Then, the engineering level is checked according to the function of the level 5 and the hexagonal hole 6. The variety of the size of the hexagonal hole 6 can be used to compare and check the size of the nut in the engineering inspection. It can also be used to check the tightness. If it is too loose, it can be tightened.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
