[0018] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.
[0019] Referring to Figure 1 , Figure 2 , Figure 3 The utility model provides a low gravity center spherical holder locking device with fine adjustment function, including main part 1, sphere 2, the sphere locking tray 3 of setting in the sphere bottom, the locking ring 4 of setting in the sphere locking tray bottom and the locking ring bracket 5 of setting in the locking ring bottom, set in the trapezoidal locking slider 6 and trapezoidal fine adjustment slider 8 of locking ring side surface, and set in the locking drive rod 7 of trapezoidal locking slider side surface and set in the fine adjustment drive rod 9 of trapezoidal fine adjustment slider side surface. The inside top of main part 1 is equipped with spherical camber 11 and sphere 2, one end of sphere locking tray 3 is equipped with spherical camber 31 and sphere 2, the other end is equipped with two parallel inclined plane 32 and with the two parallel inclined plane 41 of one end of locking ring 4 is inlaid, the other end plane 42 of locking ring 4 is pasted with the top surface 51 of locking ring bracket 5, the side of locking ring 4 is equipped with a drive boss 43 and with the plane 61 of one end of trapezoidal locking slider 6 is inlaid, the plane 81 of one end of trapezoidal fine adjustment slider 8 is pasted with the inside plane 12 of main part, the inclined plane 62 of trapezoidal locking slider 6 is pasted with the inclined plane 82 of trapezoidal fine adjustment slider 8, the end surface 71 of locking drive rod 7 is pasted with the side plane 63 of trapezoidal locking slider 6, the end surface 91 of fine adjustment drive rod 9 is pasted with the side plane 83 of trapezoidal fine adjustment slider 8, the other end 52 of locking ring bracket 5 is closely connected into an organic whole with main part 1.
[0020] The ball locking tray 3, locking ring 4, and locking ring bracket 5 are all circular ring designs, allowing the center of gravity of the ball 2 to sink accordingly. The spherical surface of the ball 2 will not interfere with the ball locking tray 3, locking ring 4, and locking ring bracket 5. The locking ring 4 has a driving boss 43 on its side that matches the plane 61 at one end of the trapezoidal locking slider 6. The end face 71 of the locking drive rod 7 pushes the side plane 63 of the trapezoidal locking slider 6, causing the trapezoidal locking slider 6 to generate a vertical force through the inclined plane 62, which acts on the driving boss 43 on the side of the locking ring 4, pushing the locking ring 4 forward and backward. Furthermore, the two parallel inclined planes 41 of the locking ring 4 act on the two parallel inclined planes 32 of the ball locking tray 3, causing the ball locking tray 3 to rise and fall, thereby achieving the locking and unlocking of the ball 2. Similarly, the end face 91 of the fine-tuning drive rod 9 pushes the side plane 83 of the trapezoidal fine-tuning slider 8, causing the trapezoidal fine-tuning slider 8 to form a vertical force with the inclined surface 62 of the trapezoidal locking slider 6 through the inclined surface 82. This force acts on the drive boss 43 on the side of the locking ring 4, pushing the locking ring 4 forward and backward. In turn, the two parallel inclined surfaces 41 of the locking ring 4 act on the two parallel inclined surfaces 32 of the ball locking tray 3, causing the ball locking tray 3 to rise and fall, thereby controlling the tightness of the ball 2.
[0021] As a further explanation of this embodiment, the operation flow of the camera gimbal fine-tuning and locking structure is now described: With all components relaxed, the ball 2 is also in a free-moving state. Thus, the end face 91 of the fine-tuning drive rod 9 slowly moves forward against the side plane 83 of the trapezoidal fine-tuning slider 8. Since the inclined surface 82 and end face 81 of the trapezoidal fine-tuning slider 8 are respectively restricted by the inclined surface 62 of the trapezoidal locking slider 6 and the inner side surface 12 of the main body 1, the trapezoidal fine-tuning slider 8 can only move forward and backward along the fine-tuning drive rod 9. Then, the trapezoidal fine-tuning slider 8 forms a vertical force with the inclined surface 62 of the trapezoidal locking slider 6, which acts on the drive boss 43 on the side of the locking ring 4 to push the locking ring 4 forward and backward. Then, through the two parallel inclined surfaces 41 of the locking ring 4, it acts on the two parallel inclined surfaces 32 of the ball locking tray 3, causing the ball locking tray 3 to rise and fall, thus realizing the fine-tuning of the ball's tightness. Based on this, the end face 71 of the locking drive rod 7 pushes the side plane 63 of the trapezoidal locking slider 6, causing the trapezoidal locking slider 6 to form a vertical force through the inclined surface 62 and the inclined surface 82 of the trapezoidal fine-tuning slider, which acts on the driving boss 43 on the side of the locking ring 4 to push the locking ring 4 forward and backward. Then, through the two parallel inclined surfaces 41 of the locking ring 4, it acts on the two parallel inclined surfaces 32 of the ball locking tray 3, causing the ball locking tray 3 to rise and fall, thereby realizing the locking and unlocking of the ball 2.
[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
