The staff inserts the support arm seat into the counterweight mounting seat and locks it by threaded connection. At the same time, a ring-shaped counterweight block can be set on the outer wall of the cantilever according to the weight of the shooting personnel, so as to achieve the effect of opposite surface balance, prevent rollover, and improve the balance during rotating shooting;

[0015] 3. The anti-skid ribs can increase the friction and prevent slipping when the photographer uses the pedal force to rotate.

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1-Figure 3As shown, a fast-rotating low-angle supporting device for sports shooting includes a base 1 as a fixed part of the device, which carries all components on the base 1, a rotating disk 4, which can swing left and right around the central axis and is connected to the moving coil 2, so that the user's swinging action can drive the moving coil 2 to rotate; the moving coil 2 is connected to the rotating disk 4 and can rotate relative to the base 1; at least one deep groove ball bearing 6 is located between the moving coil 2 and the base 1, allowing the moving coil 2 to rotate relative to the base 1 and supporting radial and axial loads at the same time; a fixed ring 3, whose inner circumferential wall surface contacts the outer ring of the deep groove ball bearing 6 to fix the axial position of the deep groove ball bearing 6, and whose outer circumferential wall surface contacts the inner circumferential wall surface of the moving coil 2 to limit the axial movement of the moving coil 2; at least two auxiliary needle bearings 5 ​​are located on both sides of the moving coil 2 and The fixed ring 3 and the base 1 are adjacent to each other, and are used to reduce the friction during the rotation of the moving coil 2, so as to make the rotation action smoother; a seat mounting seat 13 is fixed at the notch on the top surface of the rotating disk 4, and a seat cantilever 14 is detachably inserted inside the seat mounting seat 13, and a seat mounting cantilever 16 is fixed to the rear end of the seat cantilever 14, and a seat support plate 17 is arranged on the top surface of the seat mounting cantilever 16, and the seat support plate 17 is used to fix the seat (the seat is not shown in the figure), and two limit plates 18 are fixed to the bottom surface of the seat support plate 17, and the limit plates 18 are fitted with the left and right sides of the seat mounting cantilever 16, and a square nut 20 is fixed to one side of one of the limit plates 18, and two bolts 19 are arranged inside the other limit plate 18, and the threaded end of the bolt 19 passes through between the two limit plates 18 and is connected to the internal thread of the square nut 20.

[0023] During use, the staff inserts the seat cantilever 14 into the seat mounting seat 13, and locks the seat cantilever 14 and the seat mounting seat 13 by threaded connection. The photographer sits on the seat and supports the tail handle of the heavy camera with both hands. At this time, the photographer's feet are placed on the top surface of the pedal 21. When rotating shooting is required, the photographer drives the rotating disk 4 to swing left and right through the pedal force. This swinging action is transmitted to the moving coil 2 through the rotating disk 4. Since there is a deep groove ball bearing 6 between the moving coil 2 and the base 1, it can support the moving coil 2 to perform low-friction rotation. The fixed ring 3 ensures that the position of the deep groove ball bearing 6 is accurate and stable, and the auxiliary needle bearing 5 further reduces the friction resistance during the rotation process, making the rotation smoother. Through the combination of the rotating disk 4 and the moving coil 2 that can rotate 360 ​​degrees, the device can capture all-round pictures around, which is suitable for quickly and easily shooting panoramic images or videos.

[0024] like Figure 1-Figure 3As shown, a counterweight mounting seat 9 is fixed at the notch on the top surface of the rotating disk 4, and a configuration cantilever 7 is detachably inserted inside the counterweight mounting seat 9. The configuration cantilever 7 is used to place a counterweight block (the counterweight block is not shown in the figure, and the counterweight block is a metal ring structure). A first support arm seat 8 is fixed at one end of the configuration cantilever 7. Cover plates 10 are fixed at both ends of the counterweight mounting seat 9 and the seat mounting seat 13 that are close to each other. Several pillars 12 are fixed on the top surface of the base 1. A bracket 11 is arranged above the rotating disk 4. The bracket 11 is used to adapt to the bottom of the heavy camera, and the bottom surface of the bracket 11 is fixed to the top of several pillars 12. Then, the staff inserts the support arm seat 8 into the interior of the counterweight mounting seat 9 and locks it by threaded connection. At the same time, a ring-shaped counterweight block can be set on the outer wall of the configuration cantilever 7 according to the weight of the shooting personnel, so as to achieve the effect of opposite surface balance, prevent the phenomenon of rollover, and improve the balance during rotating shooting.

[0025] like Figure 1-Figure 4 As shown, during assembly, the staff needs to fix the seat to the top surface of the seat support plate 17 by threaded connection. The staff loosens the square nut 20, and can push or pull the seat support plate 17 to move forward and backward on the axis of the seat mounting cantilever 16, so as to adjust the seat to a comfortable position suitable for the shooting personnel to sit in. Then the staff tightens the square nut 20 to lock the position of the seat support plate 17. Then the staff places the heavy camera on the top surface of the bracket 11. During the placement process, it is necessary to ensure that the tail handle of the heavy camera is in the same direction as the seat support plate 17;

[0026] Three pedal seats 27 are fixed to the bottom surface of the base 1, and three pedals 21 are arranged around the base 1. A pedal bolt 26 is fixed to the bottom surface of the pedal 21. One end of the pedal bolt 26 extends out of the bottom surface of the pedal 21 and is detachably plugged into the inside of the pedal seat 27. Three second support arm seats 28 are fixed to the bottom surface of the base 1. A support arm 23 is detachably plugged into the inside of the limit plate 18. A notch for adapting to the outer wall of the support arm 23 is opened between each pedal 21. A threaded sleeve 25 is fixed to the inside of the end of the support arm 23 away from the base 1. The internal thread of the threaded sleeve 25 is connected to an adjusting foot 24. A plurality of anti-skid ribs 22 are fixed to the top surface of the pedal 21. The anti-skid ribs 22 can increase the friction and prevent slipping when the photographer rotates using the pedal force. A reinforcing rib 15 is fixed at the connection between the seat mounting cantilever 16 and the seat cantilever 14. The reinforcing rib 15 can increase the load-bearing capacity of the connection between the seat mounting cantilever 16 and the seat cantilever 14 to ensure the safety of the connection.

[0027] During assembly, the staff inserts the three pedals 21 into the periphery of the base 1 through the pedal bolts 26 and the pedal seats 27, and locks them through threaded connection. Then the staff inserts the support arm 23 into the second support arm seat 28, and locks it through threaded connection to prevent it from falling off. At this time, the staff can turn the adjustment foot 24 according to the flatness of the ground, and adjust the threaded connection between the foot 24 and the threaded sleeve 25 to fine-tune the height of the support arm 23, so as to achieve an overall stable effect. At the same time, by adjusting the foot 24 downward, the overall height can be lowered, so as to achieve a low-angle shooting effect.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
