Description

Technical Field

[0001] This utility model relates to the field of measuring tools, specifically an auxiliary ruler device for directly reading out elevation differences. Background Technology

[0002] Common methods for measuring elevation include leveling, trigonometric leveling, and barometric leveling. Leveling is the primary and most precise method for determining the elevation difference between two points. Leveling utilizes a horizontal line of sight and a leveling rod erected at a point on the ground to determine the elevation difference between two points.

[0003] In engineering elevation measurement, the elevation difference is usually obtained by measuring the elevation of a point with a level and subtracting the elevation of a reference point. This process is particularly cumbersome during site leveling, requiring a lot of repetitive calculations, which is prone to errors and inefficient. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary ruler device for directly reading the height difference.

[0005] An auxiliary ruler device for directly reading height difference includes an auxiliary ruler. The front of the auxiliary ruler is provided with height difference scale lines. A scale groove is opened in the middle of the front of the auxiliary ruler. A scale pointer is provided in the scale groove. Fixed clamps one and two are fixedly provided on the upper and lower parts of the auxiliary ruler, respectively. A gap adjustment device is rotatably provided on both the upper and lower ends of the auxiliary ruler.

[0006] Furthermore, the gap adjustment device includes multiple L-shaped flexible plates that cooperate with each other, and the multiple L-shaped flexible plates are rotatably connected to the auxiliary ruler through a rotating shaft.

[0007] Furthermore, the first fixing clamp is a bolt fastening clamp, and the second fixing clamp is a spring fastening clamp.

[0008] Furthermore, the height difference scale line includes a 0 mark, which is located in the middle of the height difference scale line. The upper part of the 0 mark consists of progressively increasing positive marks, and the lower part consists of progressively decreasing negative marks. The scale pointer is aligned with the 0 mark.

[0009] In summary, this utility model has the following beneficial effects:

[0010] This utility model is fixedly installed on one side of the tower using fixing clip one and fixing clip two. By adjusting the auxiliary ruler at its upper and lower ends and between it and the tower rod using different numbers of L-shaped flexible plates, the vertical installation of the auxiliary ruler is ensured. By moving the scale pointer into the scale groove, the pointer is brought as close as possible to the front of that section of the tower rod, ensuring the accuracy of the level instrument measurement. Data on the auxiliary ruler is read directly from the level instrument, allowing for the direct determination of the measured elevation difference without calculation, thus improving work efficiency and avoiding errors caused by calculation.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] The following is in conjunction with the appendix Figure 1-3 The present invention will be further described as follows:

[0019] An auxiliary ruler device for directly reading height difference includes an auxiliary ruler 1. The front of the auxiliary ruler 1 is provided with a height difference scale line 4. The height difference scale line 4 includes a 0 mark 41, which is located in the middle of the height difference scale line 4. The upper part of the 0 mark 41 has progressively increasing positive marks 42, and the lower part of the 0 mark 41 has progressively decreasing negative marks 43. The ruler pointer 3 is in conjunction with the 0 mark 41.

[0020] In this embodiment, when the level line 10 of the level instrument 9 is located at the 0 mark 41, the elevation difference is 0; when the level line 10 of the level instrument 9 is located at a certain mark of the positive mark 42, the elevation difference is positive; when the level line 10 of the level instrument 9 is located at a certain mark of the negative mark 43, the elevation difference is negative.

[0021] The auxiliary ruler 1 has a scale groove 2 in the middle of the front side, and a scale pointer 3 is installed in the scale groove 2. The upper and lower parts of the auxiliary ruler 1 are respectively fixedly installed with a fixing clip 5 and a fixing clip 6. The upper and lower ends of the auxiliary ruler 1 are rotatably equipped with gap adjustment devices 7. The gap adjustment device 7 includes multiple L-shaped flexible plates 71 that cooperate with each other. The multiple L-shaped flexible plates 71 are rotatably connected to the auxiliary ruler 1 through a rotating shaft 72.

[0022] In this embodiment, preferably, the first fixing clip 5 is a bolt-fastening clip, and the second fixing clip 6 is a spring-fastening clip. The auxiliary ruler 1 is fixedly installed on one side of the tower gauge 8 through the first fixing clip 5 and the second fixing clip 6. The advantage of the spring-fastening clip is that it is convenient and quick to operate, while the advantage of the bolt-fastening clip is that it is firmly fastened and can be applied to the width of each section of the tower gauge 8. The bolt-fastening clip and the spring-fastening clip are applications of prior art in this application, and their specific structures will not be described in detail.

[0023] During installation, the upper and lower ends of the auxiliary ruler 1 may connect to two adjacent sections of the tower gauge 8. Since each section of the tower gauge 8 has a different width, adjustments need to be made between the upper and lower ends of the auxiliary ruler 1 and the tower gauge 8 using a varying number of L-shaped flexible plates 71 to ensure that the auxiliary ruler 1 is vertically aligned after installation. Preferably, the L-shaped flexible plates 71 are made of flexible plastic or rubber.

[0024] In this embodiment, preferably, the scale pointer 3 is slidably disposed within the scale groove 2. A large distance between the scale pointer 3 and the front surface of the leveling rod 8 will affect the accuracy of the level instrument 9's measurements. Since each section of the leveling rod 8 has a different thickness, when the scale pointer 3 needs to engage with a thinner section of the leveling rod 8, it can be moved into the scale groove 2 to bring it as close as possible to the front surface of that section of the leveling rod 8, ensuring the accuracy of the level instrument 9's measurements.

[0025] In this embodiment, when using it, the reference point of the leveling rod 8 needs to be determined first. Then, the pointer 3 of the leveling rod is aligned with the reference point of the leveling rod 8, that is, the 0 mark 41 is aligned with the reference point of the leveling rod 8. Then, the auxiliary ruler 1 is fixedly installed on one side of the leveling rod 8 using fixing clip 5 and fixing clip 6. The level instrument 9 is used to observe and measure the auxiliary ruler 1. Figure 3 As shown, the reference point of the 8-meter gauge is "100".

[0026] Figure 4 As shown, when the level line 10 of the level instrument 9 is located... Figure 4 When the positive scale 42 is marked as "1", it means that the elevation difference is 1.

[0027] In summary, this utility model is not limited to the specific embodiments described above. Those skilled in the art can make various modifications and alterations without departing from the spirit and scope of this utility model. The scope of protection of this utility model should be determined by the claims of this utility model.
