[0032] Specifically, the rangefinder 1 measures distance using laser ranging technology. It emits laser pulses and measures the round-trip time to calculate the target distance. The base 3 supports the instrument, and the adjustable frame 4 can change its height and angle, slidingly connected to the fixed frame 5 to adjust its length for accurate measurement. The telescopic rod 8 slides within the fixed frame 5, adjusting its overall length to accommodate different distances. The spring plate 9 provides cushioning and shock absorption, protecting the instrument from damage and ensuring stable measurement. The connecting frame 10 has casters 11 for easy movement and reduced handling. The fixing pad 12 provides stable support and prevents slippage. The fixing buckle 6 and bolt 7 can fix the instrument in a specific position, suitable for long-term monitoring or precise measurement. The adjustment mechanism 2 is fixed at the bottom of the distance measuring instrument 1. The function of the adjustment mechanism 2 is to precisely adjust the various parameters of the distance measuring instrument to ensure the accuracy of its measurement. In addition, a fixing block 13 is fixedly connected to the bottom front side of the distance measuring instrument 1. The fixing block 13 provides stable support for the entire distance measuring instrument 1. A fixing groove 14 for fixing other components is opened on the inner wall front side of the adjustment plate 201. The fixing groove 14 works in conjunction with the fixing block 13, thereby improving the adaptability and connectivity of the entire distance measuring instrument 1.
[0033] Reference Figure 1 , Figure 2 and Figure 5The adjustment mechanism 2 includes an adjustment plate 201, which is rotatably connected to the bottom rear side of the distance measuring instrument 1. A bolt 202 is rotatably connected to the right side of the outer wall of the adjustment plate 201. Multiple telescopic springs 203 are fixedly connected to the front side of the inner wall of the adjustment plate 201. A clamping block 204 is slidably connected to the right side of the inner wall of the adjustment plate 201. A fixing bolt 205 is threadedly connected to the middle of the inner wall of the clamping block 204. A slide bar 206 is slidably connected to the bottom of the outer wall of the adjustment plate 201. The slide bar 206 is fixedly connected to the top of the outer wall of the base 3. A pre-aiming frame 15 is fixedly connected to the top of the outer wall of the distance measuring instrument 1. A bolt 16 is threadedly connected to the middle of the inner wall of the pre-aiming frame 15. An adjustment block 17 is rotatably connected to the middle of the inner wall of the base 3. A bolt 18 is threadedly connected to the rear side of the outer wall of the base 3.
[0034] Specifically, the adjustment plate is connected to the bottom of the rangefinder 1 and can be rotated to adjust its pitch angle. The operator can manually rotate the adjustment plate 201 to align the instrument with targets in different directions, meeting the angle requirements of various measurement scenarios. A slide bar 206 is fixed to the top of the base 3, and the bottom of the adjustment plate 201 is slidably connected to the slide bar 206, allowing for fine-tuning in the horizontal direction and improving measurement accuracy. A telescopic spring 203 on the inner wall of the adjustment plate 201 absorbs vibrations, protects the internal components of the instrument, maintains stability, and improves measurement accuracy. A clamping block 204 can slide within the adjustment plate 201 and clamps the object using a fixing bolt 205, enhancing stability and ensuring reliable measurement results. Bolt 201 is used to fix the position of the adjustment plate 201 or to cooperate with other components to achieve complex adjustments. A pre-aiming frame 15 is connected to the top of the rangefinder 1. This pre-aiming frame 15 is not only structurally stable, but also has a bolt 16 connected to its inner wall by a thread. This not only ensures the stability of the connection, but also facilitates precise adjustment. The inner wall of the base 3 also has a rotating connection function. The adjustment block 17 is installed on the base 3, providing the necessary adjustment capability for the entire rangefinder 1. In addition, in order to further enhance the stability and functionality of the rangefinder 1, bolt 18 is also connected to the outer rear side of the base 3 by a thread. This bolt 18 not only enhances the stability of the base 3, but also provides more convenience for the installation and adjustment of the instrument.
[0035] Reference Figure 1 , Figure 2 and Figure 3 The inner wall of the pulley 11 is threaded with multiple nuts 19, and the outer wall of the pulley 11 is provided with anti-slip texture 20. The top of the outer wall of the fixed frame 5 is fixedly connected with connecting blocks 21. The top of the inner wall of the adjusting frame 4 is provided with connecting grooves 22. The bottom of the outer wall of the fixed frame 5 is fixedly connected with buffer pads 23, and the bottom of the outer wall of the buffer pads 23 is fixedly connected with wear-resistant pads 24.
[0036] Specifically, the pulley 11, through multiple nuts 19 connected by its central thread, can adjust the tightness of the components related to the connecting frame 10, facilitating the disassembly, installation, and adjustment of the pulley 11's position. The anti-slip texture 20 on the outer wall of the pulley 11 increases the friction with the ground and other contact surfaces, ensuring the rangefinder is more stable and less prone to slipping during movement. The fixed frame 5, through the connecting block 21 at its top, cooperates with the connecting groove 22 on the top of the inner wall of the adjusting frame 4 to achieve a sliding connection, thereby flexibly adjusting the length of the adjusting frame 4 extending out of the fixed frame 5. The buffer pad 23 connected to the bottom of the fixed frame 5 can buffer vibration and protect the equipment when the rangefinder is moved or placed, while the wear-resistant pad 24 at its bottom can reduce friction wear with the ground and extend the service life of the components.
[0037] Working Principle: The rangefinder 1 uses laser, ultrasonic, and other rangefinding technologies to measure distance. Taking laser rangefinding as an example, the instrument emits a laser pulse. After the laser encounters the target, it reflects back. The instrument calculates the distance to the target by measuring the round-trip time of the laser and combining it with the speed of light. The base 3 supports the rangefinder 1. Multiple adjustment frames 4 are rotatably connected to the base 3. By rotating the adjustment frames 4, the height and angle of the rangefinder 1 can be changed. The bottom of the outer wall of the adjustment frame 4 is slidably connected to the fixed frame 5. The length of the adjustment frame 4 extending out of the fixed frame 5 can be adjusted as needed, thereby achieving more precise height and angle adjustment to adapt to different measurement scenarios and target positions. The telescopic rod 8 inside the fixed frame 5 can slide within the fixed frame 5 to further adjust the overall length of the rangefinder to adapt to different measurement distance requirements. Multiple spring plates 9 in the middle of the inner wall of the telescopic rod 8 play a role in buffering... The shock absorption function is that when the rangefinder is subjected to vibration or collision, the spring plate 9 deforms to absorb the impact force, protecting the rangefinder 1 and its internal precision components from damage. At the same time, it can also make the measurement results more stable and accurate. The connecting frame 10 is connected to the bottom of the telescopic rod 8. The pulleys 11 on the left and right ends of its outer wall facilitate the movement of the rangefinder on the ground or other planes, making it convenient for operators to measure in different positions and reducing the trouble of manual handling. The fixing pad 12 at the bottom of the connecting frame 10 plays a role in stabilizing support and anti-slip during measurement, preventing the rangefinder from sliding during the measurement process and ensuring the accuracy of the measurement. In addition, the fixing buckle 6 and bolt 7 on the front fixing frame 5 can be used to fix the rangefinder to certain objects to enhance its stability. It is suitable for some special measurement scenarios, such as long-term monitoring on a fixed bracket or precise measurement in a specific position.
[0038] The adjusting plate 201 is rotatably connected to the bottom rear side of the rangefinder 1. By rotating the adjusting plate 201, the pitch angle of the rangefinder 1 can be changed. When it is necessary to adjust the measuring angle of the rangefinder 1, the operator can manually rotate the adjusting plate 201 to align the rangefinder 1 with targets in different directions to meet the angle requirements in different measurement scenarios. The slide bar 206 is fixed to the top of the outer wall of the base 3, and the bottom of the outer wall of the adjusting plate 201 is slidably connected to the slide bar 206. In this way, the adjusting plate 201 can slide along the slide bar 206 in the horizontal direction, thereby driving the rangefinder 1 to make fine adjustments in the horizontal direction, so that the rangefinder 1 can be more accurately aligned with the target and improve the measurement accuracy. Multiple telescopic springs 203 on the front side of the inner wall of the adjusting plate 201 play a role in buffering and auxiliary fixing. When the rangefinder 1 is subjected to external vibration or slight impact, the springs 203 extend to provide cushioning and auxiliary fixing. The spring 203 undergoes elastic deformation, absorbing part of the impact force and reducing the impact on the rangefinder 1, protecting its internal precision components. At the same time, it can also keep the rangefinder 1 in a relatively stable state to a certain extent, which helps to improve the accuracy of the measurement. A clamping block 204 is slidably connected to the right side of the inner wall of the adjusting plate 201. The clamping block 204 can slide inside the adjusting plate 201. By tightening the fixing bolt 205, the clamping block 204 can clamp the object that needs to be fixed, such as fixing the rangefinder to a tripod or other support. This design can enhance the stability of the rangefinder during the measurement process, prevent it from shaking or moving, and ensure the reliability of the measurement results. Bolt 202 is rotatably connected to the right side of the outer wall of the adjusting plate 201. It may be used to further fix the position of the adjusting plate 201 or cooperate with other components to achieve more complex adjustment or fixing functions.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
