Description

Technical Field

[0001] This utility model relates to the field of surveying instrument technology, specifically a high-precision surveying device. Background Technology

[0002] High-precision surveying instruments are professional instruments capable of spatial measurement with millimeter-level or even sub-millimeter-level accuracy. They are widely used in fields such as engineering construction, topographic mapping, deformation monitoring, and precision installation. Their core characteristics are high precision, strong stability, and good anti-interference ability. They are usually combined with multiple sensors and advanced algorithms to ensure the reliability of measurement results.

[0003] The "High-Precision Surveying Rod" disclosed in application number "202320611044.2" includes a base plate with a rotating assembly on its upper side. The rotating assembly is used to rotate a first sleeve. A second sleeve is slidably disposed inside the first sleeve, and a third sleeve is slidably disposed inside the second sleeve. A first spring and a second spring are respectively disposed inside the first and second sleeves. The two ends of the first spring are fixed to the lower end of the second sleeve and the bottom of the inner wall of the first sleeve, respectively. The two ends of the second spring are fixed to the lower end of the third sleeve and the bottom of the inner wall of the second sleeve, respectively. The beneficial effect is that by releasing the pull rope through the rope-retracting assembly, the third sleeve will be pushed out of the second sleeve by the second spring, and the second sleeve will be pushed out of the first sleeve by the first spring, thus unfolding the device. By winding the pull rope through the rope-retracting assembly, the third sleeve will be pulled into the second sleeve by the pull rope, and the second sleeve will be pushed into the first sleeve, thus retracting the device for easy carrying. The operation is simple and convenient.

[0004] However, the above method still has the following drawbacks: Referring to the bubble level 2, the posture of the adjustable sleeve 1 can be made to be vertical to the ground without manual support, but it needs to be adjusted by the rotating shaft 1 of the rotating component. The sleeve 1 can only rotate along the rotating shaft 1, which has certain limitations. When the ground is uneven, the sleeve 1 is prone to tilting along the slope of the ground. In addition, the sleeve 1 is connected by the rotating shaft 1 and does not have a height adjustment function, resulting in poor flexibility. Utility Model Content

By engaging the mounting bracket 14 with the mounting block 13, it is easy to quickly install and disassemble the measuring rod 16. After installation, the angle of the measuring rod 16 can be freely adjusted through the damping universal joint 11. With the help of the bubble level 15, it can be quickly leveled. The operation is simple. When the ground is uneven, it can prevent the measuring rod 16 from slightly tilting along the slope of the ground, thus improving the surveying accuracy.

An arc-shaped groove is formed on one side of the clamping block 402, and a rubber pad 403 is adhered to the surface of the arc-shaped groove. A support frame 404 is fixedly provided on the other side of the clamping block 402. A through hole 405 is formed in the middle of one side of the support frame 404. A screw 406 is inserted through the through hole 405. A plug 407 is fixedly provided at one end of the screw 406, and a knob 408 is fixedly provided at the other end of the screw 406. One side of the protective shell 401 is fixedly connected to the top of the sleeve 2, and the other side of the protective shell 401 is fixed by screws.

A contraction opening 18 is opened at the top of the sleeve 2. The clamping block 402 is inserted and connected to the contraction opening 18. By rotating the screw 406 with the knob 408, the plug 407 can pull back the clamping block 402 through the support frame 404. The clamping block 402 can be contracted through the contraction opening 18, which facilitates the sliding of the telescopic column 3 and adjusts the placement height of the measuring rod 16. It has good flexibility. By rotating the screw 406 in the opposite direction with the knob 408, the clamping block 402 can clamp the telescopic column 3 through the rubber pad 403, which can ensure the firmness of the telescopic column 3 and prevent the telescopic column 3 from slipping.

A hinge seat 502 is fixedly provided on the surface of the sliding sleeve 501. A connecting rod 503 is hinged to the hinge seat 502. A hinge seat 504 is hinged to one end of the connecting rod 503. One end of the hinge seat 504 is fixedly connected to the support leg of the tripod 1. A retaining ring 6 is fixedly provided at the bottom end of the sleeve 2 to limit the sliding sleeve 501. By sliding the sliding sleeve 501, the sliding sleeve 501 can drive the connecting rod 503 to move, thereby unfolding the connecting rod 503. The sliding sleeve 501 can provide support for the support leg of the tripod 1 through the connecting rod 503, thus maintaining the stability of the tripod 1. In this embodiment, preferably, a washer 7 is fixedly provided on the top of the telescopic column 3, and an mounting plate 8 is fixedly installed on the top of the washer 7 by screws. A circular plate 10 is fixedly provided on one side of the mounting plate 8, and a mounting plate 12 is fixedly provided on the other end of the damping universal joint 11. One side of the mounting plate 12 is fixedly connected to one side of the mounting plate 8 by screws. A column groove 9 is opened on the surface of the mounting plate 8. The mounting plate 8 is sleeved on the surface of the telescopic column 3 through the column groove 9. The washer 7 can support the mounting plate 8, and the mounting plate 8 can support the circular plate 10. The mounting plate 12 can fix the damping universal joint 11 on the circular plate 10, which facilitates the installation and disassembly of the damping universal joint 11. In this embodiment, preferably, a protrusion 17 is fixedly provided on the bottom of one side of the measuring rod 16. The width of the protrusion 17 is equal to the width of the card holder 14. When the measuring rod 16 is disassembled and used to fit against the wall, the protrusion 17 and the card holder 14 can ensure the fit between the measuring rod 16 and the wall, thus ensuring the parallelism between the measuring rod 16 and the wall.

[0020] In use, first slide the sliding sleeve 501 of the reinforcing component 5. The sliding sleeve 501 can drive the connecting rod 503 to move, which can unfold the connecting rod 503. The sliding sleeve 501 can provide support for the support leg of the tripod 1 through the connecting rod 503, which can maintain the stability of the tripod 1. Then, the tripod 1 is erected on the ground. After that, the mounting bracket 14 at the top of the measuring rod 16 is engaged with the locking block 13 at one end of the damping universal joint 11, which can quickly install the measuring rod 16. Finally, the angle of the measuring rod 16 can be freely adjusted through the damping universal joint 11. With the help of the level 15, it can be quickly leveled, which can ensure the mapping accuracy of spatial measurement. When the height of the measuring rod 16 needs to be adjusted, the screw 406 is rotated by the knob 408 of the limiting component 4. The plug 407 can pull back the clamp 402 through the support frame 404. The clamp 402 can retract through the contraction port 18. Then, the telescopic column 3 is slid to adjust the placement height of the measuring rod 16. After the adjustment is completed, the screw 406 is rotated in the opposite direction by the knob 408. The clamp 402 can clamp the telescopic column 3 through the rubber pad 403, which can ensure the firmness of the telescopic column 3 and prevent the telescopic column 3 from slipping. When it is necessary to disassemble the measuring rod 16 and attach it to the wall, the surveyor vertically lifts the bracket 14 to separate it from the bracket 13, thus disassembling the measuring rod 16. Then, the protrusion 17 and the bracket 14 are attached to the wall. Since the width of the protrusion 17 is equal to the width of the bracket 14, the measuring rod 16 can be parallel to the wall, and surveying activities can be carried out.
