[0027] To better understand the purpose, structure and function of the present invention, the following further describes in detail a horizontal measuring instrument for engineering survey with a dual-stable structure of the present invention in conjunction with the drawings.

[0028] AsFigures 1-4 As shown in the figure, a horizontal measuring instrument for engineering surveying with a double-stable structure of the present utility model includes a measuring instrument 1, a circular bottom plate 8, a turntable 24, a movable support 2 and a lower fixing plate 4. A fixing pipe 5 is fixedly connected to the bottom of the lower fixing plate 4. A connecting rod 14 is inserted into the inner side of the fixing pipe 5. A ground nail 15 is fixedly connected to the bottom of the connecting rod 14. In this way, when using it on the ground, first insert the ground nail 15 into the ground, which can make the device stably fixed at this position, and greatly improve the stability of the device. The lower fixing plate 4 is connected to the movable support 2 through a rotating shaft. A first through hole 10 is provided on the surface of the movable support 2. A sliding rod 11 is inserted into the inner side of the first through hole 10. A connecting block 23 is fixedly connected to the bottom of the sliding rod 11. A threaded hole 12 is provided on the surface of the connecting block 23. A first sliding groove 13 is provided on the surface of the circular bottom plate 8. A butterfly bolt handle 16 is inserted into the inner side of the threaded hole 12. The butterfly bolt handle 16 is inserted into the inner side of the first sliding groove 13. In this way, with the circular bottom plate 8 structure provided at the bottom, when the movable support 2 and the sliding rod 11 are adjusted to the appropriate height and angle, tighten the butterfly bolt handle 16, so that the three movable supports 2 and the sliding rod 11 will form a stable structure with the circular bottom plate 8 and will not shake easily with each other, greatly improving the stability of the device.

[0029] A slider 17 is fixedly connected to the bottom of the measuring instrument 1. A second sliding groove 20 is provided on the top of the turntable 24. The slider 17 is inserted into the inner side of the second sliding groove 20. A second through hole 18 is provided on the surface of the slider 17. A third through hole 25 is provided on the surface of the turntable 24. A spherical plug rod 21 is inserted into the inner side of the second through hole 18. The spherical plug rod 21 is inserted into the inner side of the third through hole 25. A spring 19 is provided on the surface of the spherical plug rod 21. A fixed frame 7 is fixedly connected to the surface of the turntable 24. A fourth through hole 26 is provided on the surface of the fixed frame 7. The spherical plug rod 21 is inserted into the inner side of the fourth through hole 26. In this way, by inserting the slider 17 at the bottom of the measuring instrument 1 into the second sliding groove 20, the semi-circular structure at the front of the slider 17 will push the spherical plug rod 21 to slide to both sides until it is inserted into the third through hole 25 and is firmly inserted therein under the action of the spring 19. When disassembling, pull the spherical handle and pull out the plug rod to easily pull out the measuring instrument 1.

[0030] An upper fixing plate 3 is provided at the bottom of the turntable 24. The upper fixing plate 3 is fixedly connected to the bottom of the lower fixing plate 4. In this way, the turntable 24 can make the measuring level rotate 360 degrees to adjust the angle.

[0031] A pentagonal bolt handle 9 is provided on the surface of the movable support 2. The end of the pentagonal bolt handle 9 abuts against the sliding rod 11. In this way, by loosening the pentagonal bolt handle 9, the length of the sliding rod 11 can be adjusted, and then by tightening the pentagonal bolt handle 9, the positions of the movable support 2 and the sliding rod 11 are fixed, making the device more convenient to a great extent.

[0032] A retaining ring 22 is fixedly connected to the surface of the spherical plug rod 21, and the retaining rings 22 are symmetrically distributed. In this way, when the spherical plug rod 21 is inserted into the third through hole 25, the spring 19 will apply pressure to the retaining ring 22, and then the spherical plug rod 21 will be stably inserted into the third through hole 25 and will not easily slide out.

[0033] A spherical handle 6 is fixedly connected to the surface of the spherical plug rod 21, and a first handle 27 is fixedly connected to the bottom of the measuring instrument 1. In this way, when moving the measuring instrument 1, the first handle 27 provides a force application point, and pulling the handle can lift the measuring instrument 1 to move.

[0034] The working principle of the engineering survey horizontal measuring instrument with a double-stable structure: When the horizontal measuring instrument needs to be used, first pull out the connecting rod 14 by a certain distance, and then insert the ground nail 15 into the ground surface, so that the device can be stably fixed at the position where the ground nail 15 is inserted. Then loosen the butterfly bolt handle 16 and rotate the movable bracket 2, so that the non-threaded end of the butterfly bolt handle 16 slides through the first chute 13 to the position where it needs to be fixed, and then tighten the butterfly bolt handle 16. In this way, the three movable bracket 2 structures form a connected device, and they will not easily shake or move, which greatly improves the stability of the device. Then loosen the pentagon bolt handle 9, and then you can pull the first handle 27 to lift the movable slide rod 11 and the above device upward to the required height, and tighten the pentagon bolt handle 9. In this way, the device is convenient to adjust the height and has high stability. When the measuring instrument 1 and the turntable 24 need to be installed, insert the slider 17 at the bottom of the measuring instrument 1 into the second chute 20. At this time, the semi-circular slider 17 will push the spherical plug rod 21 to slide to both sides. When the slider 17 moves forward to the end, the plug rod will just insert into the third through hole 25, and under the action of the spring 19, it will be stably inserted into the third through hole 25. In this way, it is convenient to fix the measuring instrument 1 on the turntable 24. When the measuring instrument 1 needs to be disassembled, only need to pull the spherical handle 6 to both sides to drive the spherical plug rod 21 to leave the third through hole 25, and then the slider 17 can be pulled out to disassemble the measuring instrument 1. The device greatly improves the simplicity of disassembly and installation of the measuring instrument 1.
