Description

Technical Field

[0001] The present application relates to the technical field of level measurement, and in particular to an auxiliary ruler frame for a level rod. Background Art

[0002] In engineering construction, leveling is essential due to topographic survey or control network requirements. The level rod is the main tool for leveling. It mainly relies on the surveyor's hands to hold it or use two equal-length rods as support to keep it vertical. Due to wind, rain or other adverse environmental influences during field measurement, the surveyor will inevitably shake when holding the ruler, making it difficult to keep the ruler vertical, resulting in measurement errors, and the measurement accuracy will directly affect the quality of engineering construction. Although there are many auxiliary ruler frames on the market, they are usually a tripod structure composed of two rods and a level rod. Since the level rod needs to be kept vertical, the center of gravity is close to the level rod, which is easy to tip over, or the structure is too complicated, resulting in too long installation and debugging time, affecting measurement efficiency.

[0027] like Figure 1-4As shown, the embodiment of the present application provides an auxiliary ruler frame for a leveling ruler, which mainly includes a mounting portion 1 and a supporting portion 3, wherein the mounting portion 1 includes a ruler frame clamp 11 and a first connecting member 12, the ruler frame clamp 11 includes a mounting cavity 13, the mounting cavity 13 is used to mount the leveling ruler 2, and the number of the first connecting members 12 is multiple, and the multiple first connecting members 12 are respectively movably connected to the ruler frame clamp 11 and used to clamp the leveling ruler 2 in the mounting cavity 13. The supporting portion 3 includes a plurality of ruler frame legs 31 and a plurality of second connecting members 32, the ruler frame legs 31 are movably arranged on the side wall of the ruler frame clamp 11, the ruler frame legs 31 are used to support the ruler frame clamp 11, the ruler frame legs 31 can slide along the length direction of the ruler frame clamp 11 and rotate relative to the ruler frame clamp 11 at a preset angle, and the multiple second connecting members 32 are respectively movably connected to the ruler frame legs 31 and used to fix the position and rotation angle of the ruler frame legs 31.

[0028] In this embodiment, the level rod auxiliary frame can be used to install the level rod 2 through the installation part 1, and the level rod 2 can be stably supported by the support part 3. The entire structure is easy to install and convenient to operate, allowing surveyors to accurately level the level rod 2 and quickly fix the level rod 2, reducing measurement errors caused by wind, rain or other adverse environmental influences during field work, and improving measurement speed and measurement accuracy; in addition, the frame legs 31 can be selectively opened and folded up as needed for easy carrying, and the frame legs 31 can adjust the height and angle, thereby enhancing the adaptability of the level rod 2 bracket to complex terrain; the frame legs 31 located on the side of the installation part 1 have a certain forward tilt angle after opening, which can prevent the level rod 2 from tipping forward, thereby improving the overall stability of the support.

[0029] like Figure 1-4 As shown, in a specific embodiment, the ruler frame fixture 11 is a hollow rectangular parallelepiped structure, and the mounting cavity 13 extends along the length direction of the ruler frame fixture 11 and penetrates the ruler frame fixture 11; the ruler frame fixture 11 includes a first side wall 14 and a second side wall 15 opposite to each other, and the first side wall 14 is provided with a through slot 16 for observing the reading of the level rod 2, and the through slot 16 extends a preset length along the length direction of the first side wall 14. In addition, the first connecting member 12 includes a fixing knob, and the fixing knob is provided on both sides of the ruler frame fixture 11 along the length direction.

[0030] It should be noted that the ruler frame fixture 11 can also be in other shapes or structures, such as a polygonal column or a cylinder, etc., but generally speaking, because the shape of the level ruler 2 is a rectangular parallelepiped structure, the ruler frame fixture 11 with a rectangular parallelepiped structure can better adapt to the shape of the level ruler 2, making the connection between the two more compatible. As shown in the figure, in this embodiment, the first side wall 14 and the second side wall 15 are the front and back sides of the ruler frame fixture 11.

[0031] like Figure 1-4As shown, in a specific embodiment, the ruler frame fixture 11 further includes a third side wall 17 and a fourth side wall 18 opposite to each other, the third side wall 17 and the fourth side wall 18 are two side surfaces of the ruler frame fixture 11 respectively, and the number of the ruler frame legs 31 is three, and the three ruler frame legs 31 are respectively arranged on the second side wall 15, the third side wall 17 and the fourth side wall 18 of the ruler frame fixture 11. The three ruler frame legs 31 arranged on the three side surfaces of the ruler frame fixture 11 can stably support the ruler frame fixture 11.

[0032] like Figure 1-4 As shown, in a specific embodiment, the leg 31 of the ruler frame includes a leg slider 33 and a leg support foot 34, the leg support foot 34 is movably connected to the leg slider 33 and can rotate relative to the leg slider 33 at a preset angle, and the leg slider 33 is slidably connected to the ruler frame fixture 11 through a slide groove provided on the side wall of the ruler frame fixture 11.

In addition, different support feet can be selectively opened to support the ruler according to measurement needs. The support sharp angle set at the far end of the leg support feet 34 can facilitate the insertion of the leg support feet 34 into the soil or uneven ground, thereby increasing the stability of the entire structure.

[0034] The steps for using the auxiliary ruler frame of the level ruler in the embodiment of the present application are as follows: put the level ruler 2 into the installation cavity 13 of the ruler frame clamp 11, clamp the level ruler 2 by tightening the fixing knob, loosen the tightening button to open the ruler frame legs 31 outward, adjust the position of each ruler frame leg 31 in the slide slot, and preliminarily adjust the ruler frame legs 31 so that the level ruler 2 stands upright on the point to be measured. Further, adjust the level bubble on the level ruler 2, and after the bubble is centered, tighten the tightening knobs on the ruler frame legs 31 respectively to lock the ruler frame legs 31, so as to achieve the purpose of accurately supporting the level ruler 2.
