During the observation process, the surveyor needs to lean out to hold the rod, which poses safety hazards, is time-consuming and laborious, and the rod cannot be strictly vertical, which leads to a decrease in the quality of the observation data and thus affects the accuracy of the measurement results. Therefore, a special reflective device is now needed to help surveyors conduct observations.

[0003] To address the problem that surveyors cannot directly observe the bubble in the leveling rod, which causes the leveling rod to not be perfectly vertical, a new type of precision leveling rod with a reflective device is proposed to solve the above problem. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are: the precision leveling rod with reflective device not only enables quick installation and convenient angle adjustment, but also enables quick folding to align the reflective component with the observation position;

[0015] (1) By setting up a mounting pad, connecting sleeve, mounting bolt, threaded cylinder, positioning plate, anti-slip pad and connecting piece, when installing the device, first put the mounting base on the leveling scale, rotate the mounting bolt to make it rotate inside the threaded cylinder, and at the same time push the connecting piece to move. The connecting piece pushes the positioning plate to move through the connecting sleeve, and cooperates with the mounting base to position the device.

When the mounting clamp rotates, it drives the positioning plate inside the fixed cylinder to rotate. When the positioning plate rotates, it drives the positioning clips on both sides to rotate. When the angle is appropriate, the spring pieces on both sides of the positioning plate can push out the positioning clip and engage with the toothed block, thereby positioning the mounting clamp through the positioning plate and positioning the reflector through the mounting clamp, thus realizing the convenient adjustment of the reflector angle;

[0017] (3) By setting up an installation clamp, a first connecting arm, a second connecting arm, a first connecting clamp, a reflector, a threaded sleeve, fastening bolts, a second connecting clamp, and a connecting block, after installation, the first connecting arm and the second connecting arm can be pulled respectively. By folding both of them, the reflector can be moved to a suitable position and maintained at the required distance. Then, by rotating each set of fastening bolts and cooperating with the threaded sleeve, the installation clamp, the first connecting clamp, and the second connecting clamp are tightened to position the first connecting arm and the second connecting arm. Thus, the reflector is positioned by the first connecting arm and the second connecting arm, so that the reflector is aligned with the designated observation position. This achieves the ability to easily fold the reflector so that it can be aligned with the observation position. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Please refer to Figure 1-4 A precision leveling ruler with a reflective device includes a mounting base 1, a fixing cylinder 2 fixedly connected to the top of the mounting base 1, a mounting clamp 3 movably connected to the top of the fixing cylinder 2, the center line of the fixing cylinder 2 and the center line of the mounting base 1 being on the same vertical plane, a reflector 7 being provided on one side of the top of the mounting base 1, and an installation structure for quick positioning of the device being provided inside the mounting base 1.

[0025] The mounting structure includes a mounting pad 12, a mounting pad 12 fixedly connected to one side inside the mounting base 1, a threaded cylinder 16 fixedly connected to one side of the mounting base 1, a mounting bolt 15 movably connected inside the threaded cylinder 16, a connecting piece 22 fixedly connected to the mounting bolt 15 extending to the inside of the mounting base 1, a connecting sleeve 14 movably connected to the outside of the connecting piece 22, a positioning plate 17 fixedly connected to one side of the connecting sleeve 14, and an anti-slip pad 18 fixedly connected to one side of the positioning plate 17.

[0026] The centerline of the anti-slip pad 18 and the centerline of the mounting pad 12 are on the same vertical plane, and the threaded cylinder 16 is connected to the interior of the mounting base 1.

[0027] The connecting piece 22 is movably connected to the positioning plate 17, and the center line of the connecting piece 22 is on the same horizontal plane as the center line of the connecting sleeve 14.

[0028] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, when installing the device, the mounting base 1 is first fitted onto the leveling scale, and the mounting bolt 15 is rotated to make it rotate inside the threaded cylinder 16. At the same time, the connecting piece 22 is pushed to move. The connecting piece 22 pushes the positioning plate 17 to move through the connecting sleeve 14, and cooperates with the mounting base 1 to position the device. The anti-slip pad 18 on one side of the positioning plate 17 and the mounting pad 12 inside the mounting base 1 can improve the anti-slip effect and effectively prevent wear on the device and the scale after installation, thus enabling quick installation of the device.

[0029] The top of the fixed cylinder 2 is movably connected to a positioning plate 11, the inside of the fixed cylinder 2 is fixedly connected to a toothed block 19, the two sides of the positioning plate 11 are fixedly connected to a spring piece 21, and one end of one side of the spring piece 21 is fixedly connected to a positioning block 20.

[0030] The positioning block 20 is movably connected to the toothed block 19, and the positioning disc 11 passes through the fixing cylinder 2 and is fixedly connected to the mounting clamp 3;

[0031] Specifically, such as Figure 1 and Figure 3 As shown, after installation, the mounting clamp 3 can be rotated to drive the top structure to rotate, adjusting the reflector 7 to the required angle. While the mounting clamp 3 rotates, it drives the positioning plate 11 inside the fixing cylinder 2 to rotate. While the positioning plate 11 rotates, it drives the positioning blocks 20 on both sides to rotate. When the angle is appropriate, the spring pieces 21 on both sides of the positioning plate 11 can push out the positioning blocks 20 and engage with the toothed block 19, thereby positioning the mounting clamp 3 through the positioning plate 11, and then positioning the reflector 7 through the mounting clamp 3, thus realizing the convenient adjustment of the angle of the reflector 7.

[0032] The mounting clamp 3 is internally connected to a first connecting arm 4. The top of the first connecting arm 4 is fixedly connected to a second connecting clamp 10. The second connecting clamp 10 is internally connected to a second connecting arm 5. One side of the second connecting arm 5 is fixedly connected to a first connecting clamp 6. One side of the reflector 7 is fixedly connected to a connecting block 13. One side of the mounting clamp 3, one end of the second connecting clamp 10, and one end of the first connecting clamp 6 are respectively fixedly connected to a set of threaded sleeves 8. The other side of the mounting clamp 3, one end of the second connecting clamp 10, and one end of the first connecting clamp 6 are respectively movably connected to a set of fastening bolts 9.

[0033] The fastening bolt 9 extends into the interior of the threaded sleeve 8 and is threadedly connected to the threaded sleeve 8; the connecting block 13 is movably connected to the first connecting clamp 6.

[0034] The centerline of the first connecting arm 4 and the centerline of the second connecting clamp 10 are on the same vertical plane, and the centerline of the second connecting arm 5 and the centerline of the first connecting clamp 6 are on the same vertical plane.

[0035] Specifically, such as Figure 1 and Figure 2 As shown, after installation, the first connecting arm 4 and the second connecting arm 5 can be pulled respectively. By folding both, the reflector 7 can be moved to a suitable position and maintained at the required distance. Then, by rotating each set of fastening bolts 9 in conjunction with the threaded sleeve 8, the mounting clamp 3, the first connecting clamp 6 and the second connecting clamp 10 are tightened to position the first connecting arm 4 and the second connecting arm 5. Thus, the reflector 7 is positioned by the first connecting arm 4 and the second connecting arm 5, so that the reflector 7 is aligned with the designated observation position. This allows for easy folding so that the reflector 7 can be aligned with the observation position.

[0036] Working Principle: When using this invention, during installation, the mounting base 1 is first fitted onto the leveling ruler. The mounting bolt 15 is rotated to make it rotate inside the threaded cylinder 16, simultaneously pushing the connecting piece 22 to move. The connecting piece 22, through the connecting sleeve 14, pushes the positioning plate 17 to move, cooperating with the mounting base 1 to position the device. The anti-slip pad 18 on one side of the positioning plate 17 and the mounting pad 12 inside the mounting base 1 improve the anti-slip effect and effectively prevent wear on the device and the leveling ruler after installation. After installation, the mounting clamp 3 can be rotated to rotate the top structure, adjusting the reflector 7 to the required angle. Simultaneously, the rotation of the mounting clamp 3 drives the positioning disc 11 inside the fixing cylinder 2 to rotate. The rotation of the positioning disc 11... Simultaneously, the positioning blocks 20 on both sides rotate. When the angle is appropriate, the spring pieces 21 on both sides of the positioning disk 11 can push out the positioning blocks 20 and engage with the toothed blocks 19, thereby positioning the mounting clamp 3 through the positioning disk 11, and then positioning the reflector 7 through the mounting clamp 3. After installation, the first connecting arm 4 and the second connecting arm 5 can be pulled respectively. By folding both, the reflector 7 can be moved to a suitable position and maintained at the required distance. Then, each set of fastening bolts 9 is rotated to cooperate with the threaded sleeve 8 to tighten the mounting clamp 3, the first connecting clamp 6 and the second connecting clamp 10 to position the first connecting arm 4 and the second connecting arm 5, thereby positioning the reflector 7 through the first connecting arm 4 and the second connecting arm 5, so that the reflector 7 is aligned with the designated observation position.
