Description

Technical Field

[0001] The utility model relates to the technical field of level rods, in particular to a multifunctional rotary double-sided level rod. Background Art

[0002] Leveling, also known as geometric leveling, is a method of measuring the height difference between two points on the ground using a level and a level rod. A level is placed between two points on the ground, and the level rod erected at the two points is observed, and the height difference between the two points is calculated according to the readings on the rod. Usually, starting from the leveling origin or any known elevation point, the elevation of each point is measured station by station along the selected leveling route. The line divisions of the double-sided level rod and the division values ​​of the precision level rod are 10mm and 5mm. The precision level rod with a division value of 10mm has two rows of divisions. The right row of divisions is marked from 0-300cm, which is called the basic division, and the left row of divisions is marked from 300-600cm, which is called the auxiliary division. The readings of the basic division and the auxiliary division at the same height differ by a constant, which is called the base-auxiliary difference, usually also called the rod constant. It can be used to check the correctness of the readings during leveling operations.

[0003] The angle of the existing double-sided level is not convenient to adjust, and once the angle is adjusted, it is easy for the double-sided level to lose its levelness. The levelness of the double-sided level itself is the key to measurement accuracy, but the existing double-sided level is not convenient to control its own levelness, resulting in inaccurate measurement and slowing down the measurement process.

[0019] The following is a further detailed description of the features of the present invention and other related features through embodiments in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:

[0020] like Figure 1-3As shown in the figure, the numbers 1-17 respectively represent: base 1, universal ball shaft 2, adjustment plate 3, support ring 4, airbag 5, air guide tube 6, inflatable ball 7, support rod 8, rotating cylinder 9, telescopic rod 10, measuring ruler 11, connecting rod 12, air valve 13, fixing part 14, screw hole 15, support leg 16, bubble level 17.

[0021] Example: Figures 1 to 3 As shown, the multifunctional rotary double-sided level in this embodiment includes a base 1, and a plurality of outwardly inclined legs 16 are fixedly connected to the bottom of the base 1 to provide stable support. The number and position of the legs 16 can be selected according to actual requirements.

[0022] Combine Figure 1 and Figure 2 As shown, an adjustment plate 3 is movably connected to the center of the upper end surface of the base 1 via a universal ball joint 2, allowing the position of the plate 3 on the base 1 to be adjusted. A support ring 4 is provided between the base 1 and the adjustment plate 3. Two airbags 5 are slidably connected to the outer wall of the support ring 4. The outer walls of the two airbags 5 are connected to an inflatable ball 7 via an air guide tube 6. A bubble level 17 is provided on the adjustment plate 3 for checking whether the adjustment plate 3 is level.

[0023] During use, the current position status of the adjustment plate 3 is checked through the bubble level 17. When it needs to be adjusted, the adjustment plate 3 can first be flexibly moved through the universal ball shaft 2, and the interior of the airbag 5 is inflated or deflated through the inflatable ball 7. The two airbags 5 support the adjustment plate 3, and the two airbags 5 can slide on the outer wall of the support ring 4 to adjust the position of the two airbags 5, so as to facilitate the lifting or lowering of the adjustment plate 3 at different positions, thereby realizing rapid adjustment of the horizontality of the adjustment plate 3, thereby ensuring the accuracy of the level rod measurement results.

[0024] In this embodiment, if Figure 2 As shown, connecting rods 12 are fixedly connected to both the front and rear ends of the upper end face of the base 1 , and the other ends of the two connecting rods 12 are fixedly connected to the support ring 4 for fixedly supporting the support ring 4 .

[0025] like Figure 1 As shown, an air valve 13 is provided at the end of the inflatable ball 7 to facilitate the inflation and deflation of the airbag 5 .
