[0025] As can be seen from the above, by starting the adjusting motor 3, the adjusting motor 3 drives the adjusting screw 301 to rotate clockwise, and the adjusting nut seat 302 will move to the left through the adjusting screw 301. At this time, the adjusting nut seat 302 pushes the adjusting frame 11, and the sliding rod 10 on the adjusting frame 11 will move to the left through the adjusting slot 9 on the detection frame 1, thereby adjusting the length of the detection device.

[0026] Embodiment 2: The moving mechanism includes a moving frame 12, a mounting bracket 13 and a moving wheel 14. The moving frame 12 is fixedly connected to the bottom of the adjustment frame 11 and the detection frame 1. The mounting bracket 13 is fixedly connected to one side and the other side of the moving frame 12. The inner side of the mounting bracket 13 is movably connected to the moving wheel 14.

[0027] As can be seen from the above, when the detection device is moving, the moving wheels 14 enable the detection device to move normally, and the moving frame 12 enables the detection device to have a certain height so that it is not easy to collide with the ground.

[0028] Embodiment 3: The connecting assembly comprises a movable rod 4 , a movable sleeve 5 and a connecting rod 6 . The movable rod 4 is fixedly connected to the inner side of the detection frame 1 , the outer side of the movable rod 4 is movably connected to the movable sleeve 5 , and the outer side of the movable sleeve 5 is fixedly connected to the connecting rod 6 .

[0029] As can be seen from the above, since the movable sleeve 5 is movably connected to the movable rod 4, the movable sleeve 5 can rotate clockwise and counterclockwise on the movable rod 4 to easily adjust the position of the connecting rod 6.

[0030] Embodiment 4: The collection component includes a movable connecting rod 17, a collecting wheel 18, a telescopic spring 19 and a top plate 20.

[0036] Working principle: When using the road flatness detection device, the staff holds the connecting rod 6 or connects the connecting rod 6 to the vehicle, and then starts the adjustment motor 3 according to the detection requirements. The adjustment motor 3 drives the adjusting screw 301 to rotate clockwise, and the adjusting nut seat 302 moves to the left through the adjusting screw 301. At this time, the adjusting nut seat 302 pushes the adjusting frame 11, and the sliding rod 10 on the adjusting frame 11 moves to the left through the adjusting slot 9 on the detection frame 1, thereby adjusting the length of the detection device. After the adjustment is completed, the detection device can be moved through the moving wheel 14 during detection, because the telescopic spring 19 pulls one end of the movable connecting rod 17, and the movable connecting rod 17 moves through the movable shaft 16, and at the same time When the detection device is moving, the collection wheel 18 pushes the movable link 17 upward because the road is higher, and the telescopic spring 19 is stretched. At the same time, the top plate 20 releases the collection sensor 22, and the collection sensor 22 is extended and retracted. The data is collected by the data collector 8 and transmitted to the data detector 2, so as to detect the flatness of the road. When the detection device needs to be stored after the detection, the adjusting motor 3 drives the adjusting screw 301 to rotate counterclockwise, and the detection frame 1 moves to the right, and the detection frame 1 is combined with the adjusting frame 11, thus completing the use process of the utility model. The utility model has a simple structure and is safe and convenient to use.
