Description

Technical Field

[0001] This utility model relates to the field of rangefinder technology, and in particular to a rangefinder for building engineering. Background Technology

[0002] In the field of construction engineering, distance measuring instruments are an indispensable tool, widely used in all stages of construction, from preliminary site surveying and architectural design to structural erection and quality inspection during construction. Accurate distance measurement plays a crucial role in ensuring the smooth progress of projects according to design requirements. With the continuous development of the construction industry, various construction projects are becoming increasingly complex and diverse. Whether it's large commercial complexes, towering skyscrapers, or uniquely designed cultural venues, all these projects place higher demands on the performance of distance measuring instruments.

[0003] Traditional distance measuring instruments used in construction engineering typically employ simple, fixed supports and installation methods in terms of mechanical structure. Most distance measuring instruments are directly fixed to tripods of standard height, requiring operators to manually move the tripod to adjust position and angle. Their technical principle primarily relies on laser emission and reception to measure distance, but this lacks flexibility in height and angle adjustment mechanisms. For example, common distance measuring instruments are fixed to non-adjustable supports, and the angle of light emission is also relatively fixed, making it difficult to easily change according to actual measurement needs.

[0004] However, in actual construction projects, the complex and varied terrain, including uneven ground, varying floor heights, and numerous obstacles, highlights the limitations of traditional rangefinders in adjusting height. Operators struggle to quickly adjust the rangefinder to a suitable height, leading to inaccurate measurement results. Inappropriate height causes light to fail to reach the target location accurately, resulting in measurement errors. This compromises the accuracy and convenience of measurements, making the rangefinder ill-suited for the complex and diverse construction environments. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rangefinder for construction engineering, aiming to improve the problem that when operators have difficulty quickly adjusting the rangefinder to a suitable height, the measuring light cannot accurately reach the target position due to unsuitable height, resulting in measurement errors and easily affecting the accuracy and convenience of measurement.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a distance measuring instrument for building engineering, including a bracket, a placement platform fixedly connected to the upper surface of the bracket, a distance measuring instrument body disposed above the placement platform, a fixing plate fixedly connected to the upper surface of the placement platform, and an adjustment component disposed on the upper surface of the fixing plate;

[0007] The adjustment assembly includes a fixed shaft, the lower surface of which is fixedly connected to the upper surface of a fixed disk. A locking block is rotatably connected to the inner wall of the fixed shaft. A turntable is fixedly connected to the upper surface of the locking block. A locking block is fixedly connected to the outer wall of the turntable. A threaded rod is threadedly connected to the inner wall of the turntable, and a fixed sleeve is fixedly connected to the outer wall of the threaded rod.

[0008] Furthermore, a handle is fixedly connected to the outer wall of the rangefinder body, and a fixing component is provided on the lower surface of the rangefinder body.

[0009] Furthermore, the fixing component includes a fixing gripper, the lower surface of which is fixedly connected to the upper surface of the threaded rod, a turntable II is threadedly connected to the outer wall of the fixing gripper, a universal ball is fitted to the inner wall of the fixing gripper, a connecting rod is fixedly connected to the outer wall of the universal ball, and a connecting post is fixedly connected to the upper surface of the connecting rod.

[0010] Furthermore, the upper surface of the connecting column is fixedly connected to the lower surface of the rangefinder body, and the connecting column is used to drive the rangefinder body to rotate.

[0011] Furthermore, the outer wall of the threaded rod is slidably connected to the inner wall of the fixed shaft, and the threaded rod is used to adjust the height of the rangefinder body.

[0012] Furthermore, the locking block is disposed between the fixed sleeve and the fixed shaft, and the locking block is used to drive the turntable to rotate.

[0013] Furthermore, the fixing gripper is positioned above the fixing sleeve, and the fixing gripper is used to fix the omnidirectional ball.

[0014] Furthermore, the second turntable is positioned above the fixed sleeve.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, when the height needs to be adjusted, the operator rotates the turntable one, and uses the threaded relationship between the turntable one and the threaded rod to drive the threaded rod to move up and down on the inner wall of the fixed shaft, thereby realizing the rapid height adjustment of the rangefinder body. When facing different building scenarios and measurement needs, the height of the rangefinder can be flexibly adjusted, improving the accuracy and convenience of measurement, avoiding measurement errors caused by unsuitable height, and is suitable for various complex building engineering environments.

[0017] 2. In this utility model, when the operator needs to adjust the angle, he can release the locking of the fixed clamp on the universal ball by rotating the second turntable, and then freely rotate the universal ball to adjust to the appropriate angle. Afterwards, rotating the second turntable in the opposite direction will fix the universal ball again, so that the rangefinder can easily deal with various inclined and irregular surfaces in the building structure, flexibly adjust the measurement angle, reduce the measurement deviation caused by angle problems, and greatly enhance the applicability and flexibility of the rangefinder.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 - Figure 2 An embodiment of this utility model is provided: a distance measuring instrument for building engineering, including a bracket 1 to ensure that the distance measuring instrument body 5 can be placed stably on the ground during use. A placement platform 2 is fixedly connected to the upper surface of the bracket 1, and the distance measuring instrument body 5 is set on the upper surface of the placement platform 2. A fixing plate 3 is fixedly connected to the upper surface of the placement platform 2 and installed on the upper surface of the placement platform 2 to provide a fixed installation position for the adjustment component. The upper surface of the fixing plate 3 is provided with the adjustment component.

[0025] The adjustment assembly includes a fixed shaft 4, the lower surface of which is fixedly connected to the upper surface of a fixed disk 3. A locking block 9 is rotatably connected to the inner wall of the fixed shaft 4. A turntable 7 is fixedly connected to the upper surface of the locking block 9, and its inner wall is threadedly connected to a threaded rod 8. By rotating the turntable 7, the threaded rod 8 moves up and down on the inner wall of the fixed shaft 4. A locking block 9 is fixedly connected to the outer wall of the turntable 7, and the threaded rod 8 is threadedly connected to the inner wall of the turntable 7. The threaded rod 8 engages with the turntable 7 to move up and down, thereby driving the rangefinder body 5 fixed above it to move up and down, thus achieving the height adjustment function. A fixing sleeve 10 is fixedly connected to the outer wall of the threaded rod 8, providing protection and stability for the threaded rod 8. A handle 6 is fixedly connected to the outer wall of the rangefinder body 5, making it convenient for the operator to hold and move the rangefinder body 5. A fixing assembly is provided on the lower surface of the rangefinder body 5.

[0026] Specifically, firstly, the bracket 1 provides stable support for the rangefinder body 5, ensuring that the rangefinder body 5 can be placed stably on the ground in various usage scenarios, avoiding the impact of unstable placement on the measurement results. When the rangefinder body 5 needs to be installed on the placement platform 2 and its height adjusted, the operator rotates the turntable 7. The turntable 7 and the threaded rod 8 are connected by a thread, which causes the threaded rod 8 to move up and down on the inner wall of the fixed shaft 4 during the rotation of the turntable 7. Since the rangefinder body 5 is connected to the threaded rod 8, it drives the rangefinder body 5 to move up and down, achieving the effect of quickly adjusting the height of the rangefinder body 5, and can quickly adapt to the height requirements of different measurement scenarios.

[0027] Reference Figure 1 - Figure 3 The fixing component includes a fixing gripper 11, which, through threaded engagement with a turntable 12, can lock and unlock the universal ball 14, thereby controlling the angle adjustment and fixing of the rangefinder body 5. The lower surface of the fixing gripper 11 is fixedly connected to the upper surface of the threaded rod 8. The outer wall of the fixing gripper 11 is threadedly connected to the turntable 12. Rotating the turntable 12 can change the clamping degree of the fixing gripper 11 on the universal ball 14. The universal ball 14 is attached to the inner wall of the fixing gripper 11 and can rotate freely in the unlocked state of the fixing gripper 11. A connecting rod 15 is fixedly connected to the wall, and a connecting column 13 is fixedly connected to the upper surface of the connecting rod 15. The upper surface of the connecting column 13 is fixedly connected to the lower surface of the rangefinder body 5. The connecting column 13 is used to drive the rangefinder body 5 to rotate. The outer wall of the threaded rod 8 is slidably connected to the inner wall of the fixed shaft 4. The threaded rod 8 is used to adjust the height of the rangefinder body 5. The locking block 9 is set between the fixed sleeve 10 and the fixed shaft 4. The locking block 9 is used to drive the first turntable 7 to rotate. The fixed clamp 11 is set above the fixed sleeve 10. The fixed clamp 11 is used to fix the universal ball 14. The second turntable 12 is set above the fixed sleeve 10.

[0028] Specifically, when the operator rotates turntable 12, the locking state of the fixed clamp 11 on the universal ball 14 is released, and the universal ball 14 can rotate freely. The operator can adjust it to a suitable angle. After the angle is adjusted, the operator rotates turntable 12 in the opposite direction, and the fixed clamp 11 fixes the universal ball 14 again, thereby achieving the purpose of precise angle adjustment and flexibly coping with various complex building structures and measurement direction requirements.

[0029] Working principle: When a rangefinder for construction engineering is needed, firstly, the bracket 1 supports the rangefinder body 5, ensuring that the rangefinder body 5 can be placed stably on the ground during use. When the rangefinder body 5 is installed above the placement platform 2, if the height needs to be adjusted, the turntable 7 is rotated to drive the threaded rod 8 to move up and down on the inner wall of the fixed shaft 4. With the threaded relationship between the turntable 7 and the threaded rod 8, the rangefinder body 5 is moved up and down, thus achieving the effect of quickly adjusting the height of the rangefinder body 5.

[0030] Furthermore, by rotating the universal ball 14 on the inner wall of the fixed clamp 11, and in conjunction with the threaded relationship between the turntable 12 and the fixed clamp 11, when the angle needs to be adjusted, the turntable 12 is rotated to release the lock of the fixed clamp 11 on the universal ball 14, so that the universal ball 14 can be rotated. After adjusting to the appropriate angle, the turntable 12 is rotated in the opposite direction, thereby driving the fixed clamp 11 to fix the universal ball 14, thus achieving the effect of adjusting the angle.

[0031] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
