Description

Technical Field

[0001] This utility model relates to the field of measurement technology, and in particular to a tool for measuring slope ratio. Background Technology

[0002] In civil engineering, water conservancy engineering, road construction, and mining, the slope ratio, which is the ratio of vertical height H to horizontal distance L, is a key parameter for assessing slope stability, guiding construction, and conducting safety monitoring. Rapid and accurate measurement of the slope ratio is crucial for engineering safety and efficiency. Therefore, developing dedicated slope ratio measurement tools aims to simplify the measurement process, improve on-site operational efficiency, and reduce reliance on complex instruments or tedious calculations, thus possessing significant practical engineering value.

[0003] Several tools for directly measuring slope ratios have been proposed. For example, Chinese utility model patent CN220288607U discloses an instrument for measuring slope ratios. This instrument mainly includes a pole, a retractable measuring rod, and a protractor fixed to the bottom of the pole. In use, the pointed end of the pole is inserted into the soil at the foot of the slope for fixation. The bubble at the top of the pole is adjusted to ensure its verticality. Then, the measuring rod is unfolded and adjusted to fit the slope surface. Finally, the angle between the pole and the measuring rod is read on the protractor, which also marks the angle and its corresponding slope ratio value. Although this method allows for direct reading of the slope ratio, avoiding calculation, it still has significant drawbacks: 1. It requires inserting a cone to fix the upright, adjusting the length of the telescopic rod, ensuring the bubble is centered, and then adjusting the measuring rod to fit the slope surface. These multiple steps are time-consuming, making the operation cumbersome and inefficient; 2. It relies on inserting the cone into the soil for fixation, making it difficult to use or even impossible to fix on hard slopes such as rock, concrete, or frozen soil, or on ground conditions where it cannot be inserted. Therefore, it has poor terrain adaptability; 3. Including multiple telescopic rods and a cone structure, the overall size and weight are relatively large, making it inconvenient to carry and operate. Therefore, it lacks portability and ease of operation.

[0004] In summary, while existing tools for directly measuring slope ratios avoid complex calculations in principle, they still fall short in terms of efficiency, terrain adaptability, and portability, especially in meeting the engineering requirements for rapid and efficient measurements in complex terrain. Therefore, there is an urgent need to develop a new type of slope ratio measurement tool that is faster to operate, more adaptable, and simpler in structure to improve on-site measurement efficiency. Utility Model Content

[0005] In view of the shortcomings of existing technology, the technical problem solved by this utility model is to provide a tool for measuring slope ratio, thereby solving the problem of low measurement efficiency of existing measuring tools.

[0006] To solve the above problems, the technical solution adopted by this utility model is: a slope ratio measuring tool, including a slope guide, a level, a scale, and a level bubble. The slope guide and the level are rotatably connected by a hinge structure; the level is fixedly connected to the scale; the level bubble is an elongated bubble and is located on the side of the level; the center of the scale is coaxial with the center of the pin.

[0007] Compared with existing technologies, the beneficial effects of this solution are as follows: Existing technologies require cumbersome steps such as fixing the pole tip, adjusting the telescopic rod, and ensuring the bubble is centered; while this solution only requires placing the slope ruler on the slope and adjusting the level bubble to take the reading, reducing the number of steps, increasing measurement efficiency, and allowing a single person to quickly complete the slope ratio measurement with one hand.

[0008] Furthermore, the hinge structure includes a pivot pin, through which the slope ruler and the level ruler achieve 0-90° rotational positioning.

[0009] Furthermore, the dial is rigidly fixed to the level by bolts.

[0010] Furthermore, the end of the level away from the hinge structure is provided with an anti-slip grip, and the surface of the anti-slip grip is provided with a textured surface.

[0011] Furthermore, the anti-slip grip portion is provided with a support device at its end, which consists of two legs symmetrically arranged on both sides of the central axis of the anti-slip grip portion.

[0012] Furthermore, one end of the support leg is spherically hinged to the anti-slip grip, while the other end can rotate freely in the spatial plane.

[0013] Furthermore, the horizontal bubble is replaced with a circular level, which is positioned at the end of the anti-slip grip part near the hinge structure.

[0014] Furthermore, the horizontal bubble is replaced by two long spirit bubbles, which are distributed perpendicularly to each other on the top surface of the horizontal ruler. Attached Figure Description

[0019] The following detailed description illustrates the specific implementation method:

[0020] Example 1

[0021] A slope ratio measuring tool includes a slope guide 1, a level 2, a dial 3, and a level bubble 4. The slope guide 1 and level 2 are rotatably connected via a hinged structure, while the level 2 is fixedly connected to the dial 3. The level bubble 4 is located on the side of the level 2. The hinged structure allows the slope guide 1 to rotate flexibly to conform to the slope surface. The level 2, combined with the level bubble 4, allows for quick leveling to establish a measurement reference. The dial 3 facilitates direct reading of the slope ratio data. This measuring tool can quickly align with the slope surface and directly read the slope ratio data, reducing measurement time and offering convenient operation suitable for complex field terrain.

[0022] Furthermore, the slope guide 1 is used to conform to the slope surface. The slope guide 1 is made of a hard and non-deformable metal material, such as aluminum alloy, which is lightweight and easy to carry and operate. The slope guide 1 is rectangular in shape. Alternatively, the slope guide 1 can be made of high-strength plastic, which is less expensive and has some corrosion resistance. The level 2 serves to determine the horizontal reference and is made of metal. The level 2 is rectangular in shape with a flat surface to ensure measurement accuracy. Besides metal, a wooden level 2 can also be used; however, wooden level 2 needs to be treated to prevent moisture damage and maintain measurement accuracy.

[0023] Furthermore, the slope guide 1 and the level 2 are connected by a hinge structure using a pin made of stainless steel, which has high strength and wear resistance. The slope guide 1 can rotate and be positioned within a range of 0-90° around the pin. By rotating the pin, the slope guide 1 can quickly conform to the slope surface at different angles.

[0024] Furthermore, dial 3 is used to display the slope ratio data. It is circular in shape, with its center coaxial with the center of the pivot pin. Dial 3 is made of plastic, with clear graduations and slope ratio values ​​printed on its surface. Plastic is lightweight, inexpensive, and easy to process and manufacture. A metal dial 3 can also be used, as it is more durable and provides a better display. Dial 3 is rigidly fixed to the level 2 with bolts. The bolts are ordinary hexagonal bolts made of carbon steel, providing sufficient strength. Securely fixing dial 3 to the level 2 with bolts ensures a stable relative position between dial 3 and the level 2, thus accurately displaying the slope ratio data.

[0025] Furthermore, the horizontal bubble 4 is used to assist in leveling the spirit level 2. The horizontal bubble 4 is a long bubble and is set on the side of the spirit level 2.

[0026] Example 2

[0027] A non-slip grip 7 is provided at the end of the level ruler 2 furthest from the hinge structure. The surface of the non-slip grip 7 has a textured surface and is wrapped in rubber at the end of the level ruler 2. The rubber material has good elasticity and anti-slip properties, increasing the friction between the hand and the level ruler 2 and preventing the tool from slipping during operation. In addition to rubber, a silicone grip 7 can also be used, as silicone is softer and provides a better feel. A support device is located at the end of the non-slip grip 7, consisting of two legs 8 symmetrically positioned on either side of the central axis of the non-slip grip 7. The legs 8 are made of metal tubing, such as steel, providing high strength. One end of each leg 8 is spherically hinged to the non-slip grip 7, using a stainless steel ball head and socket structure. The other end of the leg 8 can rotate freely in the spatial plane. In complex terrain, the legs 8 can adjust their angle according to the ground conditions, providing stable support for the measuring tool.

[0028] The horizontal bubble 4 in Example 1 is replaced with a circular bubble 6. The circular bubble 6 is located at the end of the anti-slip grip 7 near the hinge structure. The circular bubble 6 is usually made of glass and contains liquid and bubbles. The level of the spirit level 2 is determined by observing the position of the bubbles. Glass has good transparency, making it easy to observe the position of the bubbles.

[0029] Example 3

[0030] In Example 2, the circular bubble 6 is replaced with two elongated bubble levels 5, which are perpendicularly distributed on the top surface of the level ruler 2. The elongated bubble levels 5 are also made of glass, and their precision is higher than that of the circular bubble 6, allowing for more accurate leveling of the level ruler 2. When the bubble in the level level is in the center position, it indicates that the level ruler 2 is horizontal, and the measurement reference is accurate.

[0031] The implementation principle of this embodiment is as follows: This rapid slope ratio measurement tool integrates a slope guide 1, a level 2, a dial 3, and a level bubble 4. Utilizing a hinged structure and a pivot pin, the slope guide 1 can rotate flexibly. The level bubble 4, in conjunction with the level 2, allows the measuring tool to quickly conform to the slope surface and establish an accurate measurement benchmark. The dial 3 is coaxial with the pivot pin and rigidly fixed to the level 2, facilitating direct reading of the slope ratio data. The anti-slip grip 7 and freely rotating support legs 8 enhance the ease of operation and the tool's stability in complex terrain. Compared to traditional measuring tools, this reduces instrument adjustment time, improves measurement efficiency, adapts to the operational needs of complex field terrain, and offers high measurement efficiency, allowing for rapid slope ratio measurement by a single person using only one hand.

[0032] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
