[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution:

[0022] A surveying instrument support device for surveying engineering includes a tripod 1. The tripod 1 is made of high-strength aluminum alloy, which is lightweight and corrosion-resistant. The bottom can be equipped with anti-slip pads or suction cups to adapt to different terrains. A column 2 is fixedly installed on the top of the tripod 1. The inside of the column 2 has a mounting groove 3, and an adjusting column 4 is inserted into the mounting groove 3. Locking components 5 for quickly clamping the adjusting column 4 are respectively provided on the two side walls of the column 2. A U-shaped frame 6 is fixedly connected to the top of the adjusting column 4. Clamping components 7 for positioning the surveying instrument are respectively provided on the two side walls of the U-shaped frame 6. By setting up the column 2, mounting groove 3, adjusting column 4 and locking components 5 for coordinated use, when the adjusting column 4 moves from top to bottom, the locking components 5 can automatically lock and position the adjusting column 4, which is conducive to further improving the convenience of adjustment operation. At the same time, it can support multi-level height adjustment of the surveying instrument, effectively solving the problem of low adjustment efficiency in the prior art and significantly improving the work efficiency of surveying engineering.

[0023] The locking assembly 5 includes a positioning shell 501, which is fixedly installed on one side wall of the column 2. A movable block 502 is slidably inserted into the interior of the positioning shell 501. The positioning shell 501 is made of engineering plastic and has an internal slide rail to guide the linear movement of the movable block 502. One end of the movable block 502 passes through the column 2 and is inserted into the interior of the adjusting column 4. The other end of the movable block 502 is fixedly connected to a spring 503. The spring 503 is a high-strength compression spring. The preload can ensure that the wedge-shaped part 8 and the positioning groove 9 fit tightly, while avoiding excessive compression that could cause structural damage.

[0024] One end of the movable block 502 is provided with a wedge-shaped part 8, and the side wall of the adjusting column 4 is provided with several sets of positioning grooves 9 that are adapted to the wedge-shaped part 8. The wedge-shaped part 8 is inserted into the interior of the positioning groove 9 at the corresponding position. By setting the wedge-shaped part 8 and the positioning groove 9 to work together, when the adjusting column 4 moves from top to bottom, the outer wall of the adjusting column 4 exerts a squeezing force on the wedge-shaped part 8. At this time, the movable block 502 automatically moves towards the interior of the positioning shell 501. At this time, the spring 503 is in a compressed state. After the adjusting column 4 is moved to the appropriate position, the wedge-shaped part 8 is aligned with the positioning groove 9 at the corresponding position. At this time, the rebound force of the spring 503 can be used to drive the wedge-shaped part 8 to be firmly inserted into the interior of the positioning groove 9, thereby realizing the quick clamping and positioning of the adjusting column 4, thereby lowering the height of the surveying instrument.

[0025] A pull rod 10 is fixedly connected to the end of the movable block 502 away from the wedge-shaped part 8. The pull rod 10 is slidably inserted into the inside of the positioning shell 501, and the spring 503 is movably sleeved on the outer wall of the pull rod 10. When it is necessary to raise the height of the surveying instrument, the pull rod 10 can be pulled until the wedge-shaped part 8 is completely separated from the positioning groove 9. At this time, the adjusting column 4 is lifted upward to the appropriate position, and then the pull rod 10 is released. The rebound force of the spring 503 can be used to drive the wedge-shaped part 8 to be firmly inserted into the inside of the positioning groove 9, thereby raising the height of the surveying instrument.

[0026] The clamping assembly 7 includes a screw 701, which is threaded into the side wall of the frame 6. One end of the screw 701 passes through the frame 6 and is rotatably connected to a movable plate 702. A clamping plate 703 is rotatably mounted on one side of the movable plate 702 via a damping shaft. The screw 701 adopts a trapezoidal thread design, which has excellent self-locking performance and can prevent the surveying instrument from loosening in a vibration environment. The inner side of the clamping plate 703 is covered with a rubber pad, which protects the surface of the surveying instrument and enhances friction.

[0027] It also includes an adjustment knob 704, which is fixedly connected to one end of the screw 701. The surface of the adjustment knob 704 is provided with anti-slip knurling for easy one-handed operation.

[0028] A guide rod 11 is slidably inserted into the side wall of the frame 6. One end of the guide rod 11 passes through the frame 6 and is fixedly connected to the moving plate 702. The guide rod 11 is made of stainless steel. By setting the guide rod 11, the moving plate 702 is limited, making its movement process more stable, thereby providing a stable clamping force for the surveying instrument.

[0029] Working principle: When the height of the surveying instrument needs to be lowered, the adjusting column 4 can be pressed down directly. The outer wall of the adjusting column 4 exerts a squeezing force on the wedge-shaped part 8. At this time, the movable block 502 automatically moves into the positioning shell 501. At this time, the spring 503 is in a compressed state. After the adjusting column 4 is moved to the appropriate position, the wedge-shaped part 8 is aligned with the positioning groove 9 at the corresponding position. At this time, the rebound force of the spring 503 can be used to drive the wedge-shaped part 8 to be firmly inserted into the positioning groove 9.

[0030] When it is necessary to raise the height of the surveying instrument, the pull rod 10 can be pulled until the wedge part 8 is completely separated from the positioning groove 9. At this time, the adjusting column 4 can be lifted upward to the appropriate position, and then the pull rod 10 can be released. The spring force of the spring 503 can be used to drive the wedge part 8 to be firmly inserted into the inside of the positioning groove 9, thereby raising the height of the surveying instrument. The operation is simple and quick.

[0031] When the surveying instrument needs to be installed and positioned, rotating the adjustment knob 704 causes the screw 701 to drive the moving plate 702 to move linearly along the guide rod 11. The moving plate 702 then moves the clamping plate 703 closer to the surveying instrument. The clamping plate 703 is equipped with protrusions that insert into the holes on the surveying instrument's outer shell, ultimately achieving a stable clamping. Through the coordinated design of the wedge locking and screw clamping, the height of the surveying instrument support device can be quickly adjusted and accurately positioned, significantly improving the work efficiency and stability of surveying projects.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
