[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment:

[0035] Please refer to Figures 1 - 6 , a three-dimensional stable fine-tuning cloud platform, including a triangular platform 1 provided on the top of the carbon-free trolley. The triangular platform 1 can be used to install monitoring devices, such as cameras, video recorders, etc., to record the competition process, or can also be used to install hanging pulleys to realize the travel of the carbon-free trolley using gravitational potential energy.

[0036] As shown Figure 1 in the figure, a base 2 is detachably installed on the triangular platform 1, and a mounting plate 7 with an adjusting seat 20 is movably arranged up and down on the top of the base 2. Specifically, please refer to Figure 3 the figure. A lead screw 4 is rotatably installed in the base 2. One end of the lead screw 4 is rotatably installed on the inner wall of the base 2, and the other end extends to the outside of the base 2 and is fixedly connected with an adjusting knob 5. A moving block 3 is threadedly connected to the outer wall of the lead screw 4. A ramp surface is obliquely formed on the top of the moving block 3. The lower inclined surface at the bottom of the lifting block 6 fits with the ramp surface, and the top is fixedly connected to the mounting plate 7 and is movably arranged up and down in a top groove opened on the top of the base 2;

[0037] Thus, when the lead screw 4 drives the moving block 3 to move left and right, through the cooperation between the ramp surface and the lower inclined surface, the up and down movement of the lifting block 6 can be controlled. Specifically, when the moving block 3 moves left, it will drive the lifting block 6 to rise, and when the moving block 3 moves right, the lifting block 6 will descend.

[0038] As shown Figure 1 in the figure, the two side plates of the U-shaped plate 24 are rotatably installed on the adjusting seat 20, and a monitoring device is installed on the middle plate. The monitoring device can be specifically installed by means of buckles, bolts, sliding in, etc. There is no specific limitation in this embodiment, and those skilled in the art can choose according to actual needs;

[0039] Furthermore, by controlling the lifting of the lifting block 6, the installation height of the mounting plate 7, the adjusting seat 20, the U-shaped plate 24 and the monitoring device is also controlled, realizing the adjustment of the installation height.

[0040] As shown Figure 3 in the figure, a rotating shaft is rotatably installed inside the adjusting seat 20 through a bearing. A worm gear 21 is fixedly installed on the rotating shaft. A worm 22 is engaged with the outer wall of the worm gear 21. One end of the worm 22 is rotatably installed on the inner wall of the adjusting seat 20, and the other end extends to the outside of the adjusting seat 20 and is fixedly connected with a knob 23. By turning the knob 23, the worm gear 21 can be driven to rotate by the worm 22, and then the rotation of the rotating shaft can be controlled;

[0041] As shown Figure 4 in the figure, both ends of the rotating shaft extend to the outside of the adjusting seat 20 and are fixedly connected with rectangular blocks 25, and the rectangular blocks 25 are connected to the side plates of the U-shaped plate 24. Thus, when the rotating shaft rotates, the pitching angle of the U-shaped plate 24 and the monitoring device thereon can be controlled, realizing the adjustment of the angle.

[0042] In this embodiment, a rectangular groove 26 is horizontally formed on the side plate of the U-shaped plate 24. The rectangular block 25 is slidably installed in the rectangular groove 26. In addition, a nut 27 is provided and fixedly installed on the side plate. The inner wall of the nut 27 is threadedly connected with a threaded rod 28. One end of the threaded rod 28 is rotatably connected to the rectangular block 25, and the other end is fixedly connected with an adjusting handle. Rotating the adjusting handle can adjust the position of the rectangular block 25 in the rectangular groove 26, thereby controlling the "extended length" of the entire U-shaped plate 24 and realizing the adjustment of the extended length of the monitoring device relative to the triangular platform 1. At the same time, by adjusting the extended length, the weight distribution of the monitoring device can also be controlled, thereby controlling the center of gravity of the entire carbon-free trolley.

[0043] As Figure 2 shown, an L-shaped hook plate 8 is fixedly installed on one side of the bottom of the base 2, and two sliding grooves 9 are parallelly formed on the other side. Slide columns 10 are movably arranged in both of the two sliding grooves 9. The bottom of the slide column 10 is fixedly installed with a clamping plate 11, and the diameter of the clamping plate 11 is larger than that of the slide column 10. After the base 2 is placed on the triangular platform 1, by moving the two slide columns 10 close to the L-shaped hook plate 8, the base 2 can be fixed on the triangular platform 1 by the blocking of the L-shaped hook plate 8 and the two clamping plates 11. The installation is stable and firm, and at the same time, operations such as drilling holes on the triangular platform 1 are not required.

[0044] As Figure 5 shown, the top of the slide column 10 is fixedly installed with a slider 12. The slider 12 is slidably arranged in a moving cavity 13 formed inside the moving block 3 and is supported by a support spring 14. Thus, when the moving block 3 moves leftward to raise the mounting plate 7 from the initial height position, the slider 12, the slide column 10, and the clamping plate 11 will also be driven to move. When the clamping plate 11 is stuck to the side of the triangular platform 1, the base 2 can be fixed to the triangular platform 1. At this time, even if the moving block 3 continues to move leftward, the position of the slider 12 can remain unchanged, and the continuous leftward movement of the moving block 3 is compensated by compressing the support spring 14.

[0045] Furthermore, a transmission gear 15 is also meshed with the side surface of the lifting block 6 through teeth. The transmission gear 15 is rotatably installed in the base 2, and on the other side, it is meshed with a toothed plate 16. The bottom of the toothed plate 16 is movably and telescopically provided with a pressure rod 17. Specifically, as Figure 6 shown, the top of the pressure rod 17 is fixedly installed with an inner plate 18. The inner plate 18 is movably arranged in a vertical cavity formed inside the toothed plate 16 and is supported by a lower support spring 19.

[0046] When the mounting plate 7 is raised from the initial height position, through the transmission of the transmission gear 15, the toothed plate 16 can also be moved downward. The downward movement of the toothed plate 16 drives the pressure rod 17 to move downward, so that the pressure rod 17 abuts against the triangular platform 1, thereby further ensuring the stability of the installation of the base 2.

[0047] After the compression bar 17 abuts against the triangular platform 1, if the lifting block 6 continues to rise at this time, then the compression bar 17 will compress the lower support spring 19 in the reverse direction through the inner plate 18 to adapt to the change in the position of the lifting block 6.

[0048] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
