[0015] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0016] Combined with Figure 1 , Attachment Figure 2 and attached Figure 3 A road levelness measuring device comprises a flat plate 1 and oppositely arranged upright poles 5, both sides of the bottom of the flat plate 1 are provided with oppositely arranged elastic soft clips 4 cooperating with the upright poles 5, a level sensor 2 is provided at the upper end of the flat plate 1, a display screen 3 electrically connected to the level sensor 2 is provided on one side of the flat plate 1, so as to facilitate observation of the value of the level sensor 2, and a transparent protective shell cooperating with the display screen 3 is provided on one side of the flat plate 1, so as to provide protection for the display screen 3.

[0017] Combined with Figure 1 , Attachment Figure 2 and attached Figure 3, telescopic rods 6 are provided on both sides of the flat plate 1, and one end of the telescopic rods 6 on both sides is provided with a connecting block 7. The telescopic rod 6 is a structure in which an extension rod is slidably sleeved in a sleeve, the sleeve is fixed to the flat plate 1, and the extension rod is fixed to the connecting block 7. Universal joints 8 are provided at the lower ends of the connecting blocks 7 on both sides, and mounting blocks 9 are provided at the lower ends of the universal joints 8. Mounting holes 10 are provided in the mounting blocks 9. One end of the vertical pole 5 is provided with a threaded column 11 that matches the mounting hole 10, and the other end is provided with a base 12. A non-slip pad is adhered to the base 12 to prevent the bottom of the base 12 from being worn out due to long-term contact with the ground.

[0018] When the utility model is implemented and used, when it is necessary to measure the horizontality of the road, specifically, the vertical pole is taken out from the elastic soft clamp, and then the threaded columns at the upper ends of the vertical poles on both sides are respectively aligned with the mounting holes in the mounting blocks on both sides and rotated, so that the threaded columns can be threadedly connected in the mounting holes. At this time, the base is placed on the road, and the telescopic rod can be telescopically adjusted in length as required, so as to adjust the spacing between the vertical poles on both sides. When the heights of the road where the bases at the lower ends of the vertical poles on both sides are located are different, the flat plate will tilt under the action of the universal joint, and the value of the horizontal sensor will be displayed on the display screen. The horizontality of the road can be judged by observing the value on the display screen. The structure for realizing the measurement of the road horizontality is simple, does not contain large and heavy components, and is easy to carry and use.
