Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering surveying technology, and in particular to a rangefinder for engineering surveying. Background Technology
[0002] Engineering surveying is a crucial component of construction projects, widely applied in land surveying, architectural planning, road design, and bridge construction. The accuracy of surveying directly impacts the project's implementation and subsequent safety. Especially in large-scale projects, precise distance measurement is essential to ensuring that design drawings match the actual terrain. In engineering surveying, distance measuring instruments serve as a key tool, enabling rapid and accurate measurement of distances between targets, ensuring the reliability and efficiency of survey data.
[0003] Most existing engineering surveying rangefinders use a fixed-angle support rod design, which cannot flexibly adjust the tilt angle of the support rod according to the operating environment and usage requirements. Although this fixed design is simple, it cannot provide optimal angle adaptation in different measurement scenarios, resulting in inconvenience in operation. Especially in complex terrain or confined spaces, the fixed-angle support rod limits the flexibility and accuracy of measurements. Therefore, a new engineering surveying rangefinder is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a rangefinder for engineering surveying, aiming to improve the problems of inconvenient operation and poor adaptability caused by the inability to flexibly adjust the angle of the support rod as needed in the existing technology.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A rangefinder for engineering surveying includes a counter and a roller. The counter is connected to the roller. A deflection mechanism is provided on the side wall of the counter. An adjustment mechanism is provided on the top of the deflection mechanism.
[0007] The deflection mechanism includes a fixed sleeve, the side wall of which is fixedly connected to the side wall of the counter. A toothed plate is provided inside the fixed sleeve, a spring is provided inside the fixed sleeve, a toothed plate is fixedly connected inside the fixed sleeve, a push block is slidably connected inside the toothed plate, the push block is connected to the toothed plate, and a support rod is fixedly connected to the side wall of the push block.
[0008] As a further description of the above technical solution:
[0009] The adjusting mechanism includes a sleeve, which is fixedly connected to the top of the support rod. A sliding rod is slidably connected inside the sleeve. A sliding groove is opened inside the sleeve. A fixing bolt is threaded inside the sliding rod. A flexible clamp is rotatably connected to the outside of the fixing bolt. A knob is fixedly connected to one end of the fixing bolt.
[0010] As a further description of the above technical solution:
[0011] The fixing bolt is located inside the slide groove, and the flexible clamp is located between the sleeve and the knob.
[0012] As a further description of the above technical solution:
[0013] A handle is fixedly connected to the top of the slide bar.
[0014] As a further description of the above technical solution:
[0015] One end of the spring is fixedly connected inside the fixed sleeve, and the other end of the spring is in contact with one side wall of the toothed plate.
[0016] As a further description of the above technical solution:
[0017] The first toothed plate and the second toothed plate engage with each other, and one side wall of the toothed plate is in contact with the inner wall of the fixing sleeve.
[0018] As a further description of the above technical solution:
[0019] The counter is equipped with auxiliary wheels at its bottom.
[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, by pushing the support rod, the push block slides and drives the toothed plate one to move and compress the spring. By rotating, the angle of the support rod changes. After adjustment, the support rod is released, and the spring's reverse force causes the toothed plate one to return to its original position and engage with the toothed plate two, thereby stabilizing the angle of the support rod. Through the cooperation between the above structures, the operator can adjust the tilt angle of the support rod according to actual needs to adapt to different operating environments and usage habits, thereby improving the adaptability of the equipment.
[0022] 2. In this utility model, the contact pressure between the soft clamp and the sleeve is adjusted by rotating the knob. After releasing the clamp pressure, the slide rod can slide inside the sleeve to change the grip height. After adjustment, the knob is rotated again to lock the position of the slide rod. The height is fixed by the friction between the clamp and the sleeve to ensure grip stability. Through the cooperation of the above structures, the operator can easily adjust the grip height according to personal needs, improving the comfort and accuracy of operation.

[0028] 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.
[0029] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a rangefinder for engineering surveying, comprising a counter 1 and a roller 2. The counter 1 is connected to the roller 2. Surveying work is performed through the cooperation between the counter 1 and the roller 2, which is existing technology and will not be described in detail here. The counter 1 has a deflection mechanism on its side wall to change the angle of the handheld lever for easy handling by the operator. The top of the deflection mechanism has an adjustment mechanism to change the length of the handheld lever to accommodate operators of different heights. The deflection mechanism includes a fixed sleeve 4, and the fixed sleeve 4 has a side wall... A toothed plate 5 is fixedly connected to the side wall of the counter 1. A spring 6 is installed inside the fixed sleeve 4. A toothed plate 7 is fixedly connected inside the fixed sleeve 4. A push block 8 is slidably connected inside the toothed plate 7. The push block 8 is connected to the toothed plate 5. A support rod 9 is fixedly connected to the side wall of the push block 8. One end of the spring 6 is fixedly connected inside the fixed sleeve 4. The other end of the spring 6 is in contact with the side wall of the toothed plate 5. The toothed plate 5 is engaged with the toothed plate 7. The side wall of the toothed plate 5 is in contact with the inner wall of the fixed sleeve 4. An auxiliary wheel 3 is provided at the bottom of the counter 1 to facilitate equipment stability.
[0030] During the use of the equipment, the operator can adjust the tilt angle of the support rod 9 according to their personal usage habits. By pushing the support rod 9, the push block 8 is slid into the fixed sleeve 4. The sliding of the push block 8 then pushes the toothed plate 5 to move, and at the same time compresses the spring 6. At this time, the rotation of the support rod 9 causes the toothed plate 5 to deflect inside the fixed sleeve 4, so that the tilt angle of the support rod 9 is changed. After the adjustment is completed, the operator releases the support rod 9. At this time, since the spring 6 has lost the pressure previously applied, it generates a reverse force, pushing the toothed plate 5 back to its original position, so that the toothed plate 5 re-engages with the toothed plate 7, thereby ensuring that the angle of the support rod 9 is stably fixed, thus improving the operability and stability of the equipment.
[0031] Reference Figure 1 and Figure 3 The adjustment mechanism includes a sleeve 10, which is fixedly connected to the top of the support rod 9. A slide rod 11 is slidably connected inside the sleeve 10. A slide groove 12 is opened inside the sleeve 10. A fixing bolt 13 is threaded inside the slide rod 11. A flexible clamp 14 is rotatably connected to the outside of the fixing bolt 13. A knob 15 is fixedly connected to one end of the fixing bolt 13. The fixing bolt 13 is located inside the slide groove 12. The flexible clamp 14 is located between the sleeve 10 and the knob 15. A handle 16 is fixedly connected to the top of the slide rod 11.
[0032] After adjusting the angle of the support rod 9, the contact pressure between the flexible clamp 14 and the sleeve 10 is further adjusted by rotating the knob 15. Rotating the knob 15 causes the fixing bolt 13 to rotate, gradually releasing the pressure on the flexible clamp 14 until it separates from the sleeve 10. Once the pressure on the flexible clamp 14 is released, the height of the grip 16 can be changed by pulling the slide rod 11, allowing it to slide inside the sleeve 10. The operator can then adjust the height of the grip 16 as needed to ensure comfort and precision during operation. After height adjustment, to fix the position of the slide rod 11, the knob 15 is turned again, causing the fixing bolt 13 to rotate back into the slide rod 11 and lock it. During locking, the fixing bolt 13, through its engagement with the slide rod 11, presses the flexible clamp 14 back onto the outside of the sleeve 10. The friction between the flexible clamp 14 and the sleeve 10 stabilizes the position of the slide rod 11, ensuring the stability of the grip 16 height.
[0033] Working principle: When using this equipment for surveying, by pushing the equipment to move it, the counter 1 will monitor the distance according to the rotation of the roller 2. The operator can know the surveying result through the numerical display on the top of the counter 1. When using the equipment, the operator can adjust the tilt angle of the support rod 9 according to their usage habits. By pushing the support rod 9, the push block 8 slides into the fixed sleeve 4, thereby pushing the toothed plate 5 to move and compressing the spring 6. Then, by rotating the support rod 9, the toothed plate 5 deflects in the fixed sleeve 4, thereby changing the angle of the support rod 9. After the angle adjustment is completed, the support rod 9 is released. At this time, the spring 6 loses pressure and pushes the toothed plate 5 to reset, so that the toothed plate 5 and the toothed plate 7 re-engage, thereby determining the angle of the support rod 9.
[0034] After adjusting the angle of the support rod 9, the pressure on the soft clip 14 can be gradually released by turning the knob 15 to rotate the fixing bolt 13, causing it to separate from the sleeve 10. Then, the height of the grip 16 can be changed by pulling the slide rod 11 to slide it in the sleeve 10. After adjustment, the knob 15 is turned back to rotate the fixing bolt 13 back into the slide rod 11 and squeeze the soft clip 14 again. The position of the slide rod 11 is fixed by the friction between the sleeve 10 and the soft clip 14, thereby ensuring the stability of the grip 16 height.
[0035] 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.
