Technical Field

[0001] This utility model relates to the field of measuring tool technology, and in particular to a multifunctional measuring rod structure. Background Technology

[0002] In many fields such as building construction, topographic surveying, and engineering surveying, surveying benchmarks are commonly used measuring tools. Existing surveying benchmarks have relatively limited functions, typically only capable of simple height measurements, making it difficult to meet the diverse measurement needs such as horizontal measurements in complex scenarios. Furthermore, existing benchmarks have limitations in adjusting measurement angles and maintaining measurement accuracy during the measurement process, hindering the flexible and accurate acquisition of measurement data and affecting the efficiency and quality of the measurement work. Therefore, there is an urgent need for a multifunctional surveying benchmark structure that integrates multiple measurement functions, offers high measurement accuracy, and is easy to operate; to address this, a multifunctional surveying benchmark structure 1 is provided to solve the above problems. Utility Model Content

[0003] This invention addresses the fact that current equipment and existing technologies lack suitable devices to solve the aforementioned problems. These devices often have limited functionality, typically only capable of simple height measurement, failing to meet the diverse measurement needs such as horizontal measurement in complex scenarios. This invention provides a multifunctional measuring benchmark structure for both height and horizontal measurement, effectively resolving the problems mentioned in the background section.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows:

[0005] A multifunctional measuring rod structure includes a rod and a base detachably connected to the bottom of the rod. The rod is movably fitted with a lower measuring claw and an upper measuring claw for measuring height. Above the upper measuring claw is a leveling device for adjusting the level of the laser head.

[0016] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figure 1-2 As shown, this utility model provides a multifunctional measuring rod structure, including a rod 1 and a base 2 detachably connected to the bottom of the rod 1. The rod 1 is movably fitted with a lower measuring claw 3 and an upper measuring claw 4 for measuring height. Above the upper measuring claw 4 is a leveling device for adjusting the level of the laser head 5. The leveling device includes a lower connecting plate 10 and an upper connecting plate 11 fixed above the upper measuring claw 4 and cooperating with each other. The lower connecting plate 10 and the upper connecting plate 11 have semi-circular grooves, which allow the ball head of the steering rod 12 to move and turn within them. The upper connecting plate 11 has a through hole for the steering rod 12 to turn. A level 13 is provided on the side wall of the steering rod 12.

[0018] The multi-functional measuring rod consists of a rod 1 and a detachable base 2. The base 2 is detachably installed at the bottom of the rod 1 for easy assembly and disassembly depending on the measurement scenario. The rod 1 is fitted with a lower measuring claw 3 and an upper measuring claw 4 that can move up and down. The lower and upper measuring claws 3 and 4 are aligned with the scale on the rod 1 to fix it at a specified height. Due to varying environments, the base 2 will support the rod 1 on various uneven surfaces. To ensure the laser head 5 is level, a leveling device is installed above the upper measuring claw 4 to calibrate the laser head 5. This device includes a cooperating lower connecting plate 10 and an upper connecting plate 11, both with semi-circular grooves inside. The ball end of the steering rod 12 is placed within these grooves, allowing for flexible turning. The through hole in the upper connecting plate 11 provides space for the steering rod 12 to rotate. A level 13 is mounted on the side wall of the steering rod 12, visually displaying the level status of the steering rod 12 through the bubble position. Rotate the steering lever 12 and observe the level 13. When the bubble is centered, the top laser head 5 is in a horizontal state and can project a horizontal laser line to achieve precise horizontal positioning.

[0019] The upper connecting plate 11 has a knob 14 hole for fixing the ball head. The knob 14 hole allows the knob 14 to be screwed in or out, and the knob 14 can fix or move the ball head.

[0020] A knob 14 hole is provided on the side wall of the upper connecting plate 11. The knob 14 hole is internally threaded and forms a threaded engagement structure with the externally threaded knob 14. In actual use, when the operator needs to adjust the angle of the laser head 5, the knob 14 can be turned outward along the knob 14 hole. At this time, the restraining force of the knob 14 on the ball head disappears, and the ball head can rotate freely in the semi-circular groove of the upper and lower connecting plates 10. With the movement of the steering rod 12 in the through hole, multiple angles can be flexibly adjusted. When the laser head 5 is confirmed to be horizontal by the level 13, the knob 14 is turned inward along the knob 14 hole. The end of the knob 14 gradually presses against the ball head. As the knob 14 is tightened, the ball head is firmly fixed in the semi-circular groove, so that the steering rod 12 and the top laser head 5 remain stable, ensuring that the horizontal position of the laser head 5 does not shift during operation.

[0021] The laser head 5 is located at the top of the steering rod 12, and the steering rod 12 is adjusted to make the laser head 5 horizontal.

[0022] The laser head 5 is securely mounted on the top of the steering rod 12, and the two are connected in an integrated or high-strength manner to ensure a tight fit during operation and prevent easy loosening. The ball head at the lower end of the steering rod 12 can rotate flexibly within the semi-circular groove of the upper and lower connecting plates 10, while passing through the through hole of the upper connecting plate 11, giving the steering rod 12 multiple degrees of freedom of movement. During measurement, the operator manually adjusts the angle of the steering rod 12 by observing the level 13 on the side wall of the steering rod 12. When the bubble in the level 13 is in the center position, it indicates that the steering rod 12 has reached a horizontal state, and at this time, the laser head 5 at the top is also simultaneously in a horizontal position. The horizontally positioned laser head 5 can emit a straight and precise horizontal laser line. In actual work, this laser line can be used as a horizontal reference to calibrate the flatness of the wall surface, determine the horizontal height difference, etc., providing an intuitive and accurate reference standard for the work, significantly improving the efficiency and accuracy of measurement.

[0023] The upper measuring claw 4 and the lower measuring claw 3 extend out of the base 2.

[0024] Both the upper measuring claw 4 and the lower measuring claw 3 extend beyond the base 2. Structurally, these two measuring claws act like "measuring arms" extending from both sides of the measuring rod 1, sliding up and down along the rod 1 and fixed in position by the first and second knobs. The base 2 is securely installed at the bottom of the measuring rod 1, providing support for the entire measuring rod 1. This structural design offers significant advantages when actually measuring wall height. During measurement, the base 2 of the measuring rod 1 is placed stably on the ground. Because the measuring claws extend beyond the radius of the base 2, they can easily pass over the base 2 and directly contact the wall surface. The operator can place the lower measuring claw 3 against the bottom of the wall and fix its position using the second knob, then move the upper measuring claw 4 to the top of the wall and fix it with the first knob. At this point, the scale value corresponding to the position of the upper and lower measuring claws 3 on the measuring rod 1 is read, and the difference between the two values ​​is the wall height. When calculating the wall height difference, the above measurement operation is repeated at different positions, and the difference between the different measurement results can be compared to accurately determine the height difference between different parts of the wall. This design avoids interference from the base 2's measuring claws adhering to the wall, greatly improving the accuracy and convenience of measurement, making the measurement of wall height and height difference more efficient and precise.

[0025] The surface of the benchmark 1 is engraved with scales.

[0026] The surface of the measuring rod 1 is engraved with clear and regular scales that run the entire length of the rod. These scales work in conjunction with the upper measuring jaw 4 and the lower measuring jaw 3, which are movably mounted on the rod 1, to complete the measurement. In actual measurement work, the scales play a crucial role. When using the upper measuring jaw 4 and the lower measuring jaw 3 to measure the height of a wall, after the measuring jaws are moved to the designated position, the specific length data at the location of the measuring jaws can be obtained by observing the scale markings and numbers on the side of the measuring jaws corresponding to the rod 1.

[0027] The upper measuring claw 4 is provided with a first knob, and the lower measuring claw 3 is provided with a second knob on its side wall. The first knob and the second knob can fix the upper measuring claw 4 and the lower measuring claw 3 in a specified position.

[0028] On the upper measuring jaw 4, the first knob has a screw-like structure, vertically penetrating the side wall of the upper measuring jaw 4 and making close contact with the surface of the scale rod 1; the lower measuring jaw 3 has a second knob installed on its side wall, which is also screw-like and can abut against the side of the scale rod 1. Both knobs are designed with external threads, precisely matching the corresponding internal thread holes on the side wall of the measuring jaws, allowing for smooth screwing in and out. In actual measurement, when the operator needs to adjust the position of the upper and lower measuring jaws 3, they only need to screw the first and second knobs outwards, separating the ends of the knobs from the surface of the scale rod 1, thus releasing the measuring jaws and allowing them to slide freely along the scale rod 1; when the measuring jaws move to the appropriate position, the knobs are screwed inwards. As the knobs are screwed in, their ends gradually press against the surface of the scale rod 1, using friction to firmly fix the upper measuring jaw 4 and the lower measuring jaw 3 in the designated position. In this way, whether measuring objects of different heights or performing repeated measurement operations, the measuring claws can be positioned quickly and accurately, ensuring the accuracy and stability of the measurement data and greatly improving the efficiency and precision of the measurement work. The usage process of this multifunctional measuring rod structure is as follows: First, place the rod 1 at the starting position of the measurement. When measuring the height, loosen the first knob and the second knob 14, move the upper and lower measuring claws 3 up and down, and align them with the upper and lower endpoints of the object being measured. Then, tighten the knob 14 to fix the position and read the corresponding value on the scale of the rod 1. Then, perform a horizontal measurement. Unscrew the knob 14 on the steering rod 12, rotate the steering rod 12, and observe the level 13 on its side wall. When the bubble is centered, the laser head 5 is in a horizontal state. Tighten the knob 14 to fix it. At this time, the horizontal light emitted by the laser head 5 can be used as the measurement reference to complete the horizontal positioning, calibration and other operations.
