DETAILED DESCRIPTION

[0021] Embodiment 1

[0022] like Figure 1-Figure 3 As shown, a three-dimensional coordinate measuring device proposed in this embodiment includes a protective cylinder 1, an adjustable bracket, a telescopic support rod B, a total station body 2 and two elastic sheets 7.

[0023] The protective cylinder 1 has an annular air bag 6 inside, and the protective cylinder 1 is opened at the upper end.

[0024] The adjustable bracket is installed at the bottom end of the protective cylinder 1, and the adjustable bracket includes a threaded tube 4, an adjusting member, a moving ring 19, three telescopic support rods A3 and three connecting rods 5. The threaded tube 4 is fixed at the bottom end center of the protective cylinder 1, and the three telescopic support rods A3 are rotatably installed at the bottom end of the protective cylinder 1 along a circular array. The moving ring 19 is slidably sleeved on the outer periphery of the threaded tube 4, and the three connecting rods 5 are all rotatably installed on the moving ring 19, and the other ends of the three connecting rods 5 are respectively rotatably installed on the three telescopic support rods A3. The adjusting member includes a threaded ring 15, a limit ring 16 and a fixed rod 17 fixedly connected between the threaded ring 15 and the limit ring 16. The threaded ring 15 is threadedly connected to the threaded tube 4, and the moving ring 19 is arranged between the threaded ring 15 and the limit ring 16; the sleeve 8 movably passes through the inner side of the threaded tube 4; the adjustable bracket is used to adjust the height of the total station body 2.

[0025] The telescopic support rod B includes a sleeve 8, a movable rod 9 and a support 10. The top end of the movable rod 9 is slidably arranged on the inner side of the sleeve 8, the bottom end of the movable rod 9 movably penetrates the bottom of the protective cylinder 1, and the butterfly bolt 18 is threadedly connected to the bottom end of the sleeve 8; the total station body 2 is installed at the upper end of the sleeve 8.

[0026] Two elastic sheets 7 are obliquely arranged on the inner wall of the protective cylinder 1, and the bottom end of the elastic sheet 7 is inclined toward the center of the adjacent protective cylinder 1. This structure is arranged to ensure that the turntable 11 can smoothly fall into the inner side of the protective cylinder 1, while preventing the turntable 11 from moving out from the inside of the protective cylinder 1, thereby playing a one-way limiting role; the bottom ends of the two elastic sheets 7 are fixedly connected with a pull rope 12 that passes through the side wall of the protective cylinder 1, and the ends of the two pull ropes 12 are fixed with pull rings 14. A fixing ring 13 is arranged on the outer wall of the protective cylinder 1, and the two pull ropes 12 pass through the fixing ring 13; at the same time, the two fixing rings 13 are pulled outward, which drives the pull rope 12 to move, and the pull rope 12 pulls the elastic sheet 7, thereby making it easy to take out the turntable 11 that falls into the inner side of the protective cylinder 1.

[0027] In this embodiment, during installation, the protective cylinder 1 is supported by an adjustable bracket, and then the upper end of the telescopic support rod B is adjusted so that the detection end of the total station body 2 is exposed outside the protective cylinder 1, and the bottom end of the telescopic support rod B is in contact with the ground. When the device is tilted, the telescopic support rod B moves diagonally downward, thereby driving the total station body 2 to move to the inner side of the protective cylinder 1. The turntable 11 squeezes the elastic sheet 7 when sliding, and finally the turntable 11 falls into the inner bottom end of the protective cylinder 1. The elastic sheet 7 can realize the function of limiting the total station body 2. When the device touches the ground, the entire total station body 2 is located on the inner side of the protective cylinder 1, and the annular airbag 6 can strengthen the protection of the total station body 2, thereby improving its safety.
