Description

Technical Field

[0001] The utility model relates to the technical field of pan - tilt, and specifically relates to a damping structure of a pan - tilt. Background Technique

[0002] A pan - tilt is a device used to support and adjust a camera, video camera or other optical instruments, which allows users to precisely control actions such as the pitch, yaw and sometimes roll of the device. The function of the pan - tilt is to stabilize the imaging device, prevent picture vibration caused by hand tremors or movement, and thus obtain a clear and stable shooting effect.

[0003] With the popularization of photography and videography technologies, as an important tool for stabilizing imaging devices, the performance of the pan - tilt directly affects the stability and quality of the captured images.

[0004] Traditional damping adjustment structures of pan - tilts often use simple friction methods to control the smoothness of rotation. This method not only has a limited adjustment range, but also over time, the friction material may wear, resulting in unstable damping force, affecting the service life and operating experience of the pan - tilt. Content of the Utility Model

[0005] The purpose of the utility model is to provide a damping structure of a pan - tilt to solve the problem that over time, the friction material may wear, resulting in unstable damping force, affecting the service life and operating experience of the pan - tilt.

[0006] To achieve the above - mentioned utility model purpose, the utility model adopts the following technical solutions: a damping structure of a pan - tilt, including a main seat, a regulating knob is rotatably arranged on the bottom surface of the main seat, a ball head is fixed on the top surface of the main seat, a bracket is arranged between the main seat and the ball head, a bracket resistance ring is arranged between the bracket and the ball head, an adjusting screw is arranged between the two ends of the bracket resistance ring, the bottom end of the adjusting screw is connected to the inside of the regulating knob, a ball bearing is fixed on the bottom surface of the main seat, and the inner wall of the inner ring of the ball bearing is fixedly sleeved with the outer wall of the adjusting screw.

[0007] Preferably, a plurality of fixing screws are inserted into the ball head, the fixing screws are threadedly connected to the top surface of the bracket, a first O - ring is arranged on the outer wall of the bracket, and the outer wall of the first O - ring is fitted with the inner wall of the ball head.

[0008] Preferably, a fixing seat is arranged on the inner wall of the top of the bracket, a C - shaped sealing ring is arranged on the outer wall of the fixing seat, the outer wall of the C - shaped sealing ring is mutually fitted with the inner wall of the bracket, the bottom end inside the ball head penetrates through the fixing seat and extends into the inside of the bracket, the outer wall of the adjusting screw is sleeved inside the fixing seat, and a second O - ring is arranged at the sleeve - setting position of the adjusting screw and the inside of the fixing seat.

[0009] Preferably, two connecting screws are inserted into the bracket resistance ring. The bottom end of the connecting screw penetrates through the fixing seat and is threadedly connected to the main seat. A thrust bearing is arranged on the inner wall of the main seat, and the outer wall of the thrust bearing is attached to the inner bottom surface of the bracket.

[0010] Preferably, a deep groove ball bearing is fixedly sleeved on the inner wall of the main seat. A positioning ring is arranged on the bottom surface of the main seat. An M8 screw is sleeved inside the positioning ring. The threaded end of the M8 screw penetrates through the deep groove ball bearing, the C-shaped sealing ring and is threadedly connected to the bracket.

[0011] Preferably, a C-shaped sealing ring is sleeved on the outer wall of the fixing seat. The outer wall of the C-shaped sealing ring is in contact with the inner wall of the bracket. A third O-ring is arranged at the middle position inside the fixing seat. The inner wall of the third O-ring is attached to the outer wall of the inner bottom end of the bracket.

[0012] Compared with the prior art, a pan-tilt damping structure adopting the above technical scheme has the following beneficial effects:

[0013] First, during use, the user drives the adjusting screw to move up and down by rotating the adjusting knob. Since a ball bearing is installed below the adjusting knob, this ensures the stability and smoothness of the rotation of the adjusting knob.

[0014] The top end of the adjusting screw has a tapered surface. When it moves up and down, it interacts with the adjusting screw with a tapered surface. This interaction causes the effective outer diameter of the bracket resistance ring to change. As the adjusting screw moves downward, the outer diameter of the bracket resistance ring shrinks; conversely, when moving upward, the outer diameter increases. When the outer diameter of the bracket resistance ring increases, its fit with the ball head becomes tighter, thereby increasing the damping force, that is, the rotational resistance felt by the user is greater. On the contrary, if the outer diameter decreases, the damping force is reduced and the rotation is lighter. Damping grease is filled inside the ball head, and the surface of the bracket resistance ring is covered with a wear-resistant sheet made of cork material. Such a combination can generate a uniform and stable damping force during relative movement, thereby providing a good photography feel and picture stability.

[0015] Second, during use, C-shaped sealing rings, the first O-ring, the second O-ring, and the third O-ring are used for sealing to ensure that the damping grease filled inside the ball head will not leak. In addition, sealant is applied on the contact surface between the bracket and the ball head to enhance the sealing effect. The presence of the deep groove ball bearing and the thrust bearing ensures that the connecting parts of the pan-tilt do not get stuck during movement, and at the same time ensures the smooth movement and uniform rotation speed of the main seat. The ball head and the bracket, as a group of interrelated components, produce a precisely controlled relative movement with other components. Description of the Drawings

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] like Figures 1-5 As shown, a pan / tilt damping structure comprises a main seat 5, an adjusting knob 1 is rotatably provided on the bottom surface of the main seat 5, a ball head 17 is fixed on the top surface of the main seat 5, a bracket 7 is provided between the main seat 5 and the ball head 17, the inside of the ball head 17 is filled with damping grease, a bracket resistance ring 14 is provided between the bracket 7 and the ball head 17, the surface of the bracket resistance ring 14 is covered with a wear-resistant sheet made of cork, an adjusting screw 15 is provided between the two ends of the bracket resistance ring 14, the bottom end of the adjusting screw 15 is connected to the inside of the adjusting knob 1, a ball bearing 2 is fixed to the bottom surface of the main seat 5, the inner wall of the inner ring of the ball bearing 2 is fixedly sleeved with the outer wall of the adjusting screw 15, and a A plurality of fixing screws 18 are threadedly connected to the top surface of the bracket 7. A first O-ring 8 is provided on the outer wall of the bracket 7. The outer wall of the first O-ring 8 fits with the inner wall of the ball head 17. A fixing seat 11 is provided on the inner wall of the top of the bracket 7. A C-shaped sealing ring 10 is provided on the outer wall of the fixing seat 11. The outer wall of the C-shaped sealing ring 10 fits with the inner wall of the bracket 7. The inner bottom end of the ball head 17 passes through the fixing seat 11 and extends to the inside of the bracket 7. The outer wall of the adjusting screw 15 is sleeved with the inside of the fixing seat 11. A second O-ring 12 is provided at the sleeve between the adjusting screw 15 and the inside of the fixing seat 11. The contact surface between the bracket 7 and the ball head 17 is coated with sealant.

[0024] In use, the user drives the adjusting screw rod 15 to move up and down by rotating the adjusting knob 1. Since a ball bearing 2 is installed below the adjusting knob 1, this ensures the stability and smoothness of the rotation of the adjusting knob 1;

[0025] The top end of the adjusting screw rod 15 has a tapered surface. When it moves up and down, it interacts with the adjusting screw rod 15 which also has a tapered surface. This interaction causes the effective outer diameter of the bracket resistance ring 14 to change. As the adjusting screw rod 15 moves downward, the outer diameter of the bracket resistance ring 14 shrinks; conversely, when it moves upward, the outer diameter increases. When the outer diameter of the bracket resistance ring 14 increases, its fit with the ball head 17 becomes tighter, thereby increasing the damping force, that is, the rotational resistance felt by the user is greater. On the contrary, if the outer diameter decreases, the damping force is reduced and the rotation is lighter. Damping grease is filled inside the ball head 17, and the surface of the bracket resistance ring 14 is covered with a wear-resistant sheet made of cork material. Such a combination can generate uniform and stable damping force during relative movement, thereby providing a good photographic feel and picture stability.

[0026] As Figures 1-4 shown, two connecting screws 16 are inserted into the bracket resistance ring 14. The bottom ends of the connecting screws 16 penetrate through the fixing seat 11 and are threadedly connected to the main seat 5. A deep groove ball bearing 6 is fixedly sleeved on the inner wall of the main seat 5. A positioning ring 4 is arranged on the bottom surface of the main seat 5. An M8 screw 3 is sleeved inside the positioning ring 4. The threaded end of the M8 screw 3 penetrates through the deep groove ball bearing 6, the C-shaped sealing ring 10 and is threadedly connected to the bracket 7. The C-shaped sealing ring 10 is sleeved on the outer wall of the fixing seat 11. The outer wall of the C-shaped sealing ring 10 is in contact with the inner wall of the bracket 7. A third O-ring 13 is arranged at the middle position inside the fixing seat 11. The inner wall of the third O-ring 13 fits with the outer wall of the bottom end inside the bracket 7.

[0027] In use, the C-shaped sealing ring 10, the first O-ring 8, the second O-ring 12 and the third O-ring 13 are used for sealing treatment to ensure that the damping grease filled inside the ball head 17 will not leak. In addition, sealant is applied on the contact surface between the bracket 7 and the ball head 17 to enhance the sealing effect. The presence of the deep groove ball bearing 6 and the thrust bearing 9 ensures that the connecting parts of the pan-tilt will not get stuck during movement, and at the same time ensures the smooth movement and uniform rotation speed of the main seat 5. The ball head 17 and the bracket 7, as a group of interrelated components, generate precisely controlled relative movement with other components.
