Description

Technical Field

[0001] This utility model relates to the field of measuring tool technology, and in particular to a measuring tool with an adjustable angle. Background Technology

[0002] Slope measuring tools are essential equipment in engineering planning and construction, used to ensure that the flatness and inclination of engineering structures meet design requirements. Traditional slope measurement methods may rely on visually observing the movement of a spirit level to determine the angle, but this method has limited accuracy and is easily affected by the observer's subjective factors. Therefore, with the development of technology, adjustable-angle electronic slope measuring tools have emerged.

[0003] Adjustable-angle slope measuring tools are indispensable equipment in modern engineering technology. Their high precision, ease of use, and versatility make them essential tools in all stages of engineering planning, construction, installation, decoration, renovation, supervision, quality control, and acceptance. With continuous technological advancements, the performance and functionality of these tools will continue to improve to meet increasingly complex and diverse engineering measurement needs.

[0004] Existing slope measurement tools are generally suitable for fixed engineering structures where the slope is known and does not change. Users may not need to frequently adjust the measurement angle or have particularly high requirements for the accuracy of the measurement angle. Therefore, measuring tools with non-adjustable angles can meet the needs. However, when multiple different slopes occur in a project, multiple slope measurement tools with fixed angles need to be carried, which limits portability. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-7 An adjustable-angle measuring tool includes a reference rod 1, with a measuring rod 2 rotatably mounted at one end of the reference rod 1. A fixing mechanism is provided between the reference rod 1 and the measuring rod 2, and an angle adjustment mechanism is provided at the rotatable connection between the reference rod 1 and the measuring rod 2. During the use of this device, the slope angle is determined by the size of the angle between the reference rod 1 and the measuring rod 2. The angle adjustment mechanism allows the user to easily change the angle between the reference rod 1 and the measuring rod 2, and the fixing mechanism keeps the positions of the reference rod 1 and the measuring rod 2 relatively fixed, preventing external forces from causing changes in the angle between the reference rod 1 and the measuring rod 2.

[0027] As a preferred embodiment, the angle adjustment mechanism includes a connecting shaft 3, which is fixedly installed at one end of the measuring rod 2. The connecting shaft 3 is located at the rotatable connection between the measuring rod 2 and the reference rod 1, and is rotatably adapted to the reference rod 1. Multiple spherical slots 4 are provided at both ends of the connecting shaft 3. Multiple ball-head locking posts 5 are slidably installed at the rotatable connection between the reference rod 1 and the measuring rod 2. Springs 6 are fixedly connected between the multiple ball-head locking posts 5 and the reference rod 1. The ball-head locking posts 5 and the spherical slots... 4-phase compatibility; In this device, there are 360 ​​ball-head locking posts 5 and spherical slots 4, evenly arranged in a ring, so that the angle formed between two spherical slots 4 and the center origin of the connecting shaft 3 is 1°. When the measuring rod 2 is rotated by external force, the ball-head locking post 5 will be pushed out of the spherical slot 4. When the ball-head locking post 5 coincides with the next spherical slot 4, it will be pushed back into the spherical slot 4 by the spring 6. In the user's perception, every time the measuring rod 2 rotates one degree, the measuring rod 2 will feel resistance again, which helps the user to accurately adjust to the required angle.

[0028] As a preferred technical solution of this embodiment, a scale 7 is engraved at the rotatable connection between the reference rod 1 and the connecting shaft 3. The scale 7 is engraved with corresponding numbers (not shown in the figure), and a pointer groove 8 is provided on the top of the connecting shaft 3. The scale 7 can have corresponding numbers from 0 to 90. When the reference rod 1 and the measuring rod 2 coincide, the pointer groove 8 points to the 0 mark on the scale 7. As the measuring rod 2 rotates, the mark on the scale 7 pointed to by the pointer groove 8 will also change, making it easy for the user to determine the current angle between the measuring rod 2 and the reference rod 1 at a glance.

[0029] As a preferred embodiment, the fixing mechanism includes a fixing rod 9, which is rotatably mounted on the side wall of the reference rod 1. A movable groove 10 is provided on the fixing rod 9. A support pad 11 is fixedly mounted on the side wall of the measuring rod 2. The support pad 11 is slidably disposed inside the movable groove 10. A fixing nut 12 is threadedly connected to the top of the support pad 11. The fixing rod 9 is disposed between the fixing nut 12 and the support pad 11. After the measuring rod 2 and the reference rod 1 are unfolded, the fixing rod 9 rotates with the change in the angle of the measuring rod 2. At this time, the position of the support pad 11 inside the movable groove 10 changes. When the measuring rod 2 rotates to a specified angle, by rotating the fixing nut 12, the support pad 11 and the fixing nut 12 press and fix the fixing rod 9 between them, making the position of the fixing rod 9 immutable, thereby locking the reference rod 1 and the measuring rod 2.

[0030] As a preferred technical solution in this embodiment, the side wall of the fixing nut 12 is provided with an anti-slip groove 13; the anti-slip groove 13 prevents slippage when rotating the fixing nut 12.

[0031] As a preferred embodiment, the reference rod 1 has a storage groove 14 inside, the measuring rod 2 is rotatably disposed inside the storage groove 14, and the reference rod 1 has a through groove 15 on its side wall, which is connected to the storage groove 14. The support pad 11 is disposed inside the through groove 15. The measuring rod 2 and the support pad 11 are stored in the storage groove 14 and the through groove 15, so that the device can completely store the fixing rod 9 and the measuring rod 2 on the reference rod 1, saving space and making it easy to carry.

[0032] As a preferred technical solution in this embodiment, one end of the measuring rod 2 is rotatably connected to a vertical rod 16. After the vertical rod 16 is rotated and unfolded, the angle between it and the measuring rod 2 is 90°. A level tube 17 is embedded in both the measuring rod 2 and the vertical rod 16. In use, the vertical rod 16 and the measuring rod 2 form a right angle. During measurement, the reference rod 1 is in contact with the slope surface. When the horizontal bubble inside the level tube 17 on the measuring rod 2 and the vertical rod 16 is centered, the slope measurement is qualified.
