[0026] Example

[0027] like Figures 1-7 As shown, a road smoothness rapid detection tool includes a cross frame 1 with a cross-shaped groove along its length, a cross-shaped slide plate 2 sliding inside the cross-shaped groove, and a number of I-shaped plates 3 distributed vertically through the cross-shaped slide plate 2. When the cross-shaped slide plate 2 moves, the paths of two adjacent I-shaped plates 3 overlap.

[0028] The side of the "I" shaped plate 3 is provided with several square slots 4 that are equally spaced along its height direction. The "+" shaped slide plate 2 has a triangular block 5 that matches the square slots 4 that slides along its length direction. When the triangular block 5 is locked inside the square slot 4, the top surface of the triangular block 5 coincides with the inner top surface of the square slot 4, and the inclined surface of the triangular block 5 contacts the bottom edge of the square slot 4.

[0029] The cross-shaped slide plate 2 is equipped with a return spring 6 that presses the triangular block 5 towards the side of the I-shaped plate 3.

[0030] When a rapid test of road flatness is required, the staff first places the crossbeam 1 on the road. Due to the pressure of the ground, the "I" shaped plate 3 with the square slot 4 will be pressed upward. At this time, the "I" shaped plate 3 will press the inclined surface of the triangular block 5, causing the triangular block 5 to move away from the "I" shaped plate 3 until both ends of the crossbeam 1 are completely in contact with the ground. Then, the "+" shaped sliding plate 2 is moved along the length of the crossbeam 1 to move the "I" shaped plate 3. When there is a protrusion on the ground, the bottom of the "I" shaped plate 3 will be pressed upward. Since the paths of two adjacent "I" shaped plates 3 overlap, this testing tool can be used to conduct a comprehensive test of the road.

[0031] The cross-shaped slide plate 2 has through holes 201 that correspond one-to-one with the I-shaped plate 3. The I-shaped plate 3 passes through the through holes 201 and slides in conjunction with the through holes 201.

[0032] By opening the through hole 201, the "I" shaped plate 3 can pass through the "+" shaped slide plate 2, making it easy for the "I" shaped plate 3 to slide along the vertical direction of the "+" shaped slide plate 2;

[0033] The upper surface of the cross-shaped slide plate 2 is provided with a receiving cavity 202 that communicates with the through hole 201. A guide groove 203 is provided on one of the opposite inner walls of the receiving cavity 202. The two sides of the triangular block 5 are fixed with guide blocks 7 located inside the guide groove 203 and slidingly engaged with the guide groove 203.

[0034] By opening the receiving cavity 202, the triangular block 5 can be located inside the receiving cavity 202. By combining the guide groove 203 and the guide block 7, the triangular block 5 can slide along the length direction of the crossbeam 1.

[0035] A bent tube 8 is fixed on the triangular block 5. A fixed rod 204 is fixed above the cross-shaped slide plate 2. A movable plate 205 is slidably sleeved on the outside of the fixed rod 204. The lower surface of the movable plate 205 contacts the upper surface of the cross-shaped slide plate 2. Several protrusions 206 are fixed on the movable plate 205, which are distributed along the length of the movable plate 205 to press against the bent tube 8.

[0036] The movable plate 205 can drive the protrusion 206 to move. The protrusion 206 squeezes the bent tube 8, causing all the bent tubes 8 to move to the right. At this time, the triangular block 5 will disengage from the inside of the square slot 4, and the return spring 6 will contract and shorten. All the "I" shaped plates 3 will fall due to gravity, making it convenient for the next inspection.

[0037] An extension shaft 301 is fixedly installed at the bottom of the "I" shaped plate 3, which is distributed along its length direction. The bottom surface of the extension shaft 301 is an arc surface.

[0038] By setting the extension shaft 301, the extension shaft 301 can be made to contact the road surface when the "I" shaped plate 3 moves left and right. By setting the bottom end surface of the extension shaft 301 as an arc surface, the extension shaft 301 can be easily slid in the left and right directions.

[0039] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
