[0028] Embodiment 1:

[0029] Please refer to Figures 1-4 , the above technical solutions of the present utility model are described in detail through the following embodiments:

[0030] A folding ruler for highway detection, comprising:

[0031] The detection ruler 1, the detection ruler 1 includes two folding rulers 11, the two folding rulers 11 are rotatably connected through a rotating hinge 12, an installation groove 15 is provided on the side of the detection ruler 1, a horizontal measurement assembly 2 is provided in the installation groove 15, and the horizontal measurement assembly 2 is connected with an angle adjustment assembly 3.

[0032] The folding ruler 11 is made of aluminum alloy material,

[0033] A buckle 14 is welded to the top surface and the front side surface of the left folding ruler 11, and a clamping plate 13 is rotatably installed on the top surface and the side surface of the right folding ruler 11.

[0034] The clamping plate 13 is used to be clamped with the buckle 14 to limit the rotation of the folding ruler 11.

[0035] An anti-collision block 16 is clamped at the end of the folding ruler 11, and the anti-collision block 16 is made of plastic material. It is used to prevent accidental bumps.

[0036] The horizontal measurement assembly 2 includes a level 23, the level 23 is used to detect the levelness, and a rotating assembly is provided below the level 23; the rotating block is rotatably installed in the installation groove 15;

[0037] The level 23 adopts a well-known cylindrical bubble level, and the outside is wrapped with a metal shell.

[0038] The rotating assembly includes a sector-shaped rotating block 21. The sector-shaped rotating block 21 is rotatably installed in the installation groove 15 through a rotating shaft 22. The top surface of the sector-shaped rotating block 21 is flush with the top surface of the installation groove 15. A scale 25 is provided on the front side of the sector-shaped rotating block 21.

[0039] The rotating shaft 22 is welded and installed at the center position of the sector-shaped rotating block 21. The rotating shaft 22 is rotatably connected to the folding ruler 11. The interval of the scale 25 is 1°. The scale 25 faces the axis of the rotating shaft 22.

[0040] The spirit level 23 is fixedly installed on the top surface of the sector-shaped rotating block 21 by screws. Limit blocks 24 are provided on both the front and rear sides of the spirit level 23 beyond the sector-shaped rotating block 21. The limit blocks 24 are used to abut against the folding ruler 11.

[0041] When the sector-shaped rotating block 21 rotates, it can drive the spirit level 23 to rotate around the rotating shaft 22. When rotating, the rotation angle can be judged through the scale 25.

[0042] An arc-shaped rack 26 is welded and installed on the arc-shaped side surface of the sector-shaped rotating block 21.

[0043] The center of the arc-shaped rack 26 coincides with the center of the sector-shaped rotating block 21.

[0044] The angle adjustment assembly 3 includes an adjustment gear 31. The adjustment gear 31 is connected to the rotating assembly. The adjustment gear 31 is connected with a driving assembly through a transmission shaft 32. The driving assembly is used to drive the adjustment gear 31 to rotate, so as to drive the rotating assembly to rotate. The arc-shaped rack 26 meshes with the adjustment gear 31.

[0045] The transmission shaft 32 is rotatably connected to the folding ruler 11. When the adjustment gear 31 rotates, it can drive the sector-shaped rotating block 21 to rotate through the arc-shaped rack 26.

[0046] The driving assembly includes a worm gear 33. The worm gear 33 is fixedly installed on the transmission shaft 32. A worm 34 meshes with the side surface of the worm gear 33. The worm 34 is perpendicular to the transmission shaft 32.

[0047] When the worm 34 rotates, it can drive the worm gear 33 to rotate, so as to drive the adjustment gear 31 to rotate through the transmission shaft 32.

[0048] It should be noted that the worm gear 33 cannot drive the worm 34 to rotate.

[0049] A second rotating shaft 35 is clamped on the top surface of the worm 34. The top of the second rotating shaft 35 penetrates through the folding ruler 11 and is clamped with an adjustment knob 36.

[0050] Rotating the adjustment knob 36 can drive the second rotating shaft 35 to rotate, so as to drive the worm 34 to rotate.

[0051] When the operator in this embodiment uses this device, the clamping plate 13 on the side of the folding ruler 11 is separated from the buckle 14 on the side, and the folding ruler 11 is rotated until the two folding rulers 11 are flush. Then, the clamping plate 13 on the top surface of the folding ruler 11 is rotated to engage with the buckle 14 on the top surface, ensuring that the folding ruler 11 cannot rotate.

[0052] The side of the folding ruler 11 without the horizontal measurement component 2 is abutted against the road surface.

[0053] By observing the level 23, it is judged whether the road surface is horizontal at this time. If the road surface is not horizontal.

[0054] The adjusting knob 36 is rotated to drive the second rotating shaft 35 to rotate, thereby driving the worm 34 to rotate. The rotation of the worm 34 drives the worm wheel 33 to rotate, thereby driving the adjusting gear 31 to rotate through the transmission shaft 32, and further driving the sector-shaped rotating block 21 to rotate through the arc-shaped rack 26. The rotation of the sector-shaped rotating block 21 drives the level 23 to rotate.

[0055] During the rotation of the sector-shaped rotating block 21, the state of the level 23 is observed in real time until the level 23 is horizontal, and the scale 25 on the front side of the sector-shaped rotating block 21 is observed at this time.

[0056] The scale 25 flush with the side surface of the folding ruler 11 is the included angle between the level 23 and the folding ruler 11, that is, the slope of the road surface.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions in the specification are only preferred examples of the present invention and do not limit the present invention.
