DETAILED DESCRIPTION
[0019] The following is combined with Figure 1-4 This application is described in further detail.
[0020] The present application embodiment discloses a fixing bracket of a surveying instrument, referring to Figure 1-Figure 4, including a triangular prism 1, a fixed plate 2 is fixedly connected to the top of the triangular prism 1, a turntable 3 is rotatably connected to the top of the fixed plate 2, a plurality of mounting holes 4 are provided on the turntable 3, and movable supporting mechanisms are arranged on the three sides of the triangular prism 1, the movable supporting mechanisms include a connecting block 7, a slider 8, an extension rod 9, a fixing sleeve 10, a universal wheel 12 and a supporting foot 18, a limiting mechanism is arranged at the bottom of the triangular prism 1, and the surveying instrument can be fixed on the top of the turntable 3 through the mounting hole 4, and the surveying direction of the surveying instrument can be adjusted by rotating the turntable 3, and the surveying instrument can be supported above the surveying point through the fixed plate 2 by unfolding the three movable supporting mechanisms, and the height of the surveying instrument can be changed by adjusting the angle of the movable supporting mechanism, and the limiting mechanism can play a role of limiting and fixing the three movable supporting mechanisms.
[0021] Reference Figure 2 The connecting block 7 is rotatably connected to the two fixed blocks 5 through the rotating shaft 6. The two fixed blocks 5 are fixedly connected to the side walls of the triangular prism 1. The two ends of the bottom of the connecting block 7 are fixedly connected to the two sliders 8 respectively. The bottoms of the two sliders 8 are fixedly connected to the fixing sleeves 10. The two sliders 8 are slidably connected with the extension rod 9. A bolt 11 is threadedly connected to one side of the fixing sleeve 10. One end of the slider 8 can be pulled to drive the other end of the slider 8 to rotate around the rotating shaft 6, thereby unfolding the three movable support mechanisms. The extension rod 9 can be slid downward along the slider 8 to extend the movable support mechanism. The bolt 11 is turned inward to make one end of the bolt 11 press the extension rod 9 tightly, so that the extension rod 9 is fixed to the slider 8, and the three movable support mechanisms are adjusted to the same height and angle, thereby adjusting the height of the turntable 3 and the surveying instrument.
[0022] Reference Figure 1 and Figure 3 One end of the extension rod 9 movably passes through the fixed sleeve 10 and is fixedly connected with the universal wheel 12 and the supporting foot 18. The supporting foot 18 is located on the inner side of the bottom of the extension rod 9, and in the vertical state, the height of the supporting foot 18 is slightly lower than the universal wheel 12. When the three movable supporting mechanisms are retracted, the three extension rods 9 are in a vertical state, the three universal wheels 12 are close to the ground, and the three supporting feet 18 are suspended in the air, which can hold the fixed bracket and move the fixed bracket through the three universal wheels 12. When the three movable supporting mechanisms are unfolded, the extension rod 9 is in an inclined state, and the three inner supporting feet 18 are close to the ground, providing three stable supporting points for the turntable 3, and the three universal wheels 12 are suspended in the air, which is convenient for the movement and support of the fixed bracket.
[0023] Reference Figure 3 and Figure 4The limiting mechanism includes a fixing column 13, a ring 15 and a connecting rod 17. The top of the fixing column 13 is fixedly connected to the middle part of the bottom of the triangular prism 1. The ring 15 is movably sleeved on the outer surface of the fixing column 13. The outer surface of the ring 15 is rotatably connected to the three connecting rods 17. The other ends of the three connecting rods 17 are rotatably connected to the inner sides of the three fixing sleeves 10 respectively. A limiting groove 14 is provided on the top of the fixing column 13. A bolt 2 16 is threaded through one side of the ring 15. The bolt 2 16 is adapted to the limiting groove 14. By screwing the bolt 2 16, the ring 15 can slide down along the fixing column 13 as the three movable supporting mechanisms are unfolded, and the three connecting rods 17 rotate and tilt accordingly. When the positions of the three movable supporting mechanisms are determined, the bolt 2 16 is rotated inwardly, so that one end of the bolt 2 16 can be inserted into the limiting groove 14 and squeeze the limiting groove 14, thereby fixing the ring 15 and the fixing column 13, thereby fixing the three movable supporting mechanisms, and thus stably supporting the surveying instrument.
[0024] The implementation principle of a fixed bracket of a surveying instrument in the embodiment of the present application is as follows: by setting a movable supporting mechanism and a limiting mechanism, the surveying instrument can be fixed on the top of the turntable 3 through the mounting hole 4, one end of the slider 8 can be pulled, thereby driving the other end of the slider 8 to rotate around the rotating shaft 6, thereby unfolding the three movable supporting mechanisms, sliding the extension rod 9 downward along the slider 8 to extend the movable supporting mechanism, turning the bolt 11 inward so that one end of the bolt 11 presses the extension rod 9, so that the extension rod 9 is fixed to the slider 8, and the three movable supporting mechanisms are adjusted to the same height and angle, thereby adjusting the height of the turntable 3 and the surveying instrument, and turning the bolt 21 inward so that the extension rod 9 is pressed against the extension rod 9, so that the extension rod 9 is fixed to the slider 8, and the three movable supporting mechanisms are adjusted to the same height and angle, thereby adjusting the height of the turntable 3 and the surveying instrument, and turning the bolt 12 inward so that the extension rod 9 is pressed against the extension rod 9, so that the extension rod 9 is fixed to the slider 8, and the three movable supporting mechanisms are adjusted to the same height and angle, and then the height of the turntable 3 and the surveying instrument is adjusted. 6, one end of the second bolt 16 can be inserted into the limiting groove 14 and squeeze the limiting groove 14, thereby fixing the ring 15 and the fixing column 13, so that the three movable supporting mechanisms are fixed. At this time, the extension rod 9 is in an inclined state, and the three inner supporting feet 18 are close to the ground, providing three stable supporting points for the turntable 3, and the three universal wheels 12 are suspended in the air. When the three movable supporting mechanisms are retracted, the three extension rods 9 are in a vertical state, the three universal wheels 12 are close to the ground, and the three supporting feet 18 are suspended in the air, so that the fixed bracket can be supported and the fixed bracket can be moved by the three universal wheels 12, which has the effects of flexible adjustment, stable fixation and easy movement.
