[0021] Embodiment

[0022] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the technical solution in the embodiments of the present application effectively solves the technical problem that the existing control method is to manually use a leveling rod and a tape measure for height control, which is greatly affected by human factors, resulting in a deviation in height between the edge and the curbstone after the surface layer paving is completed, affecting the road quality and appearance quality. The general idea is as follows:

[0023] In view of the problems existing in the prior art, the present utility model provides an adjustable laser-assisted leveling rod, including a first leveling rod plate 1, a second leveling rod plate 2, a threaded rod 3, a lifting block 4, a laser pen 5, a limiting rod 6, a knob 7, a scale ruler 8, an insertion ring 9, an insertion rod 11 and a hinge 12. The size of the first leveling rod plate 1 is 100 cm in length and 15 cm in width, and the size of the second leveling rod plate 2 is 90 cm in length and 15 cm in width.

[0024] The hinge 12 is installed at the connection of the first leveling rod plate 1 and the second leveling rod plate 2. The threaded rod 3 is rotatably installed at the side end of the first leveling rod plate 1. The limiting rod 6 is fixedly installed at the side end of the first leveling rod plate 1. The lifting block 4 is slidably installed at the side end of the first leveling rod plate 1; the lifting block 4 is slidably connected with the limiting rod 6, and the lifting block 4 is threadedly connected with the threaded rod 3.

[0025] The laser pen 5 is installed at the side end of the lifting block 4. The scale ruler 8 is opened at the side end of the second leveling rod plate 2. The knob 7 is fixedly installed at the top end of the threaded rod 3. The insertion rod 11 is installed at the side end of the first leveling rod plate 1. The insertion ring 9 is fixedly installed at the side end of the second leveling rod plate 2; the insertion ring 9 corresponds to the insertion rod 11.

[0026] Working principle:

[0027] First step, both the first ruler plate 1 and the second ruler plate 2 are made of stainless steel, which can effectively reduce the influence of asphalt adhesion on measurement data. When in use, lean the first ruler plate 1 and the second ruler plate 2 against the road curbstone, and the height of the road curbstone can be read through the scale ruler 8 opened at the side end of the second ruler plate 2. Turn on the laser pen 5, and the laser pen 5 will emit a laser beam. Rotate the knob 7. Since the knob 7 is fixedly connected to the threaded rod 3, rotating the knob 7 will drive the threaded rod 3 to rotate. Since the threaded rod 3 is threadedly connected to the lifting chuck 4, and at the same time the lifting chuck 4 is slidably connected to the limiting rod 6, rotating the threaded rod 3 can make the lifting chuck 4 slide up and down along the limiting rod 6. When the laser beam emitted by the laser pen 5 irradiates on the top plane of the asphalt, stop rotating the threaded rod 3, and the height of the asphalt pavement can be read by observing the scale position irradiated by the laser beam. By comparing the height corresponding to the road curbstone and the height irradiated by the laser, the height difference between the two can be obtained, so as to be adjusted during subsequent construction. By utilizing the characteristic that light travels in a straight line, the measured data is made more accurate.

[0028] Second step, when the measurement is completed, rotate the second ruler plate 2 to fold the second ruler plate 2 with the first ruler plate 1. After the second ruler plate 2 and the first ruler plate 1 are folded, slide the insertion rod 11 downward so that the insertion rod 11 is inserted into the insertion ring 9 to complete the fixation. Connect the first ruler plate 1 and the second ruler plate 2 through the hinge 12, so that the first ruler plate 1 and the second ruler plate 2 can be folded, achieving the effect of being convenient for storage.

[0029] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, rather than limiting the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
