Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 5 As shown, the utility model provides a photographic pan head locking device, including a photographic pan head body 1, wherein a movable component 2 and a locking component 3 are respectively installed inside the photographic pan head body 1, wherein the movable component 2 includes a rotating rod 21, a rotating column 22 and a centrifugal block 23, wherein the top surface of the rotating rod 21 is rotatably connected to the bottom surface of the rotating column 22, and the top surface of the rotating column 22 is fixedly connected to the bottom surface of the centrifugal block 23, the centrifugal block 23 is in an irregular state as a whole, and the centrifugal block 23 is located at the connection between the rotating rod 21 and the rotating column 22.

[0023] The above scheme is adopted: by setting the rotating rod 21, the rotation of the rotating rod 21 is used to drive the rotating column 22 and the centrifugal block 23 to move synchronously, and the irregular state of the centrifugal block 23 is used to drive the first movable plate 33 and the second movable plate 34 to move toward the outside of the limit frame 15.

[0024] like Figures 3 to 5As shown, the photographic head body 1 includes a fixed plate 11, a limit block 12, a support column 13, a rotating drum 14 and a limit frame 15. The bottom surface of the fixed plate 11 is fixedly connected to the top surface of the limit block 12, the top end of the support column 13 is rotatably connected to the inner wall of the limit block 12, the bottom surface of the rotating drum 14 is rotatably connected to the center of the top surface of the fixed plate 11, and the top surface of the rotating drum 14 is fixedly connected to the bottom surface of the rotating rod 21. The interior of the limit frame 15 is hollow, and the bottom surface of the centrifugal block 23 is in contact with the inner bottom wall of the limit frame 15, and the top surface of the limit frame 15 is provided with two sets of grooves.

[0025] The above scheme is adopted: through the setting of the fixed plate 11 and the rotating drum 14, the camera can be stably rotated under the drive of the limit frame 15, so as to facilitate the camera to shoot the surrounding environment. Through the setting of the support column 13, the stability of the entire device can be ensured while supporting the device. Through the setting of the limit frame 15, the first movable plate 33 and the second movable plate 34 are more stable during the movement.

[0026] like Figure 2 and Figure 5 As shown, the locking assembly 3 includes a first movable plate 31, a second movable plate 32, a first activity plate 33, a second movable plate 34 and a telescopic spring 35. The bottom surface of the first movable plate 31 is fixedly connected to the top surface of the first movable plate 33, the bottom surface of the second movable plate 32 is fixedly connected to the top surface of the second movable plate 34, and one side of the first movable plate 31 and the second movable plate 32 are in contact with the outer surface of the centrifugal block 23. Both ends of the telescopic spring 35 are fixedly connected to the connection between the first movable plate 33 and the second movable plate 34. The outer surfaces of the first movable plate 31 and the second movable plate 32 are slidably connected to the inside of the groove, and the first movable plate 33, the second movable plate 34 and the telescopic spring 35 are all located inside the limit frame 15.

[0027] The above scheme is adopted: through the setting of the first movable plate 31 and the second movable plate 32, the position of the camera can be fixed to prevent the camera from falling when shooting on the photography gimbal, and through the setting of the telescopic spring 35, the position of the moved first movable plate 31 and the second movable plate 32 can be restored to the original state by utilizing its own contractility, and a certain pressure is applied to the first movable plate 31 and the second movable plate 32 by its own contraction force, so that the first movable plate 31 and the second movable plate 32 can better fix the position of the camera.

[0028] The working principle and use process of the utility model are as follows: first, the device is placed on a stable bottom surface, and the support column 13 is spread out, and then the rotating rod 21 is rotated, so that the centrifugal block 23 rotates under the drive of the rotating column 22, and the pressure generated by the rotation of the centrifugal block 23 drives the first movable plate 33 and the second movable plate 34 to move as a whole toward the outside of the limit frame 15. At this time, the first movable plate 31 and the second movable plate 32 will follow the first movable plate 33 and the second movable plate 34 to move synchronously.

[0029] The distance between the first movable plate 31 and the second movable plate 32 is maximized, and then the bottom of the camera is placed above the limit frame 15. At this time, the rotating rod 21 is swung to its original position. When the telescopic spring 35 is under the pressure brought by the centrifugal block 23, it will continue to shrink. At the same time, the first movable plate 31 and the second movable plate 32 will continue to approach each other following the telescopic spring 35, and contact with the bottom of the camera. The position of the camera is fixed by the pressure generated by the contraction of the telescopic spring 35. At this point, the overall operation process is completed.
