Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0016] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0017] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0018] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0019] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0020] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element.

[0021] Example This embodiment provides a road testing instrument for road surface inspection, such as... Figure 1 and Figure 2 As shown, it includes a smoothness adjustment mechanism 1000 and a laser ranging mechanism 2000. The laser ranging mechanism 2000 is arranged along the length direction of the smoothness adjustment mechanism 1000 and can slide along the length direction to detect the road surface below.

[0022] The flatness adjustment mechanism 1000 includes a mounting plate 1100 and telescopic legs 1200. The mounting plate 1100 is used to provide a mounting platform. The mounting plate is provided with a sliding groove along its length for mounting the laser rangefinder 2000. The telescopic legs 1200 are located at the four bottom corners of the mounting plate 1100.

[0023] In this embodiment, the telescopic column base 1200 can be an electric telescopic rod, with its length controlled by a remote control. Alternatively, it can be a screw structure, with one end passing through and screwed onto the mounting plate 1100, and the other end resting on the ground; its height can be adjusted by rotating the screw.

[0024] The bottom of the telescopic column base 1200 is covered with an anti-slip sleeve to enhance the friction between the rest of the ground and improve stability.

[0025] The mounting plate 1100 is also equipped with a bubble level 4000 on its top. The bubble level 4000 is used to observe the overall flatness of the device and works in conjunction with the telescopic column feet 1200 to adjust the flatness of the device. An inclination sensor can also be used to measure its flatness more intuitively and accurately. It can also be connected to an electric telescopic rod, which automatically levels itself after obtaining the inclination data.

[0026] The laser ranging mechanism 2000 includes a linear guide rail 2100, which is arranged in a sliding groove. A laser rangefinder 2200 is mounted on the linear guide rail 2100. The upper end of the laser rangefinder 2200 is slidably connected to the linear guide rail 2100, and its ranging end faces the ground. The laser rangefinder 2200 can slide on the linear guide rail 2100 by means of a drive mechanism or manually.

[0027] In this embodiment, a light-shielding curtain 3000 is provided around the bottom of the mounting plate 1100, and a telescopic canopy 2300 is provided between the laser rangefinder 2200 and the sliding groove. The light-shielding curtain 3000 and the telescopic canopy 2300 work together to create a relatively dark and enclosed detection environment, reducing the impact of outdoor light changes and dust and water mist on the distance measurement of the laser rangefinder 2200.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
