[0020] The following will make a detailed description of the implementation manners of the present utility model in conjunction with the accompanying drawings.

[0021] As Figures 1 to 3 shown, the present utility model discloses an anti-rotation pan-tilt locking structure, which includes a pan-tilt main body 1, a pan-tilt base assembly 2 provided on the upper part of the pan-tilt main body 1 for installing a camera device, and a sphere 3 provided on the lower part of the pan-tilt main body 1. A locking ring 11 is rotatably connected to the pan-tilt main body 1. The pan-tilt main body 1 is further provided with a threaded member 41. A rotating mechanism 5 capable of driving the threaded member 41 to rotate when the locking ring 11 rotates is provided between the locking ring 11 and the threaded member 41. A guide seat 42 that is threadedly connected to the threaded member 41 and guides the threaded member 41 to move in the up and down direction when the threaded member 41 rotates is provided on the pan-tilt base assembly 2 or the pan-tilt main body 1. A locking structure 6 capable of locking the pan-tilt main body 1 and the sphere 3 when the threaded member 41 presses downward is provided between the pan-tilt main body 1 and the sphere 3.

[0022] The pan-tilt main body 1 is used to support the components. The pan-tilt base assembly 2 provides a platform for installing a camera device or other loads, and a clamping assembly can be provided on the pan-tilt base assembly 2 to facilitate the quick installation and disassembly of the device. The sphere 3 provides free rotation of the pan-tilt main body 1 in multiple directions to achieve omnidirectional shooting angle adjustment. The threaded member 41 is linked with the locking ring 11 through the rotating mechanism 5, so that when the locking ring 11 rotates, the threaded member 41 can be driven to rotate through the rotating mechanism 5. The guide seat 42 guides the threaded member 41 to move in the up and down direction when rotating. The locking structure 6 can lock the pan-tilt main body 1 and the sphere 3 together when the threaded member 41 presses downward. The user can adjust the up and down movement of the threaded member 41 through the locking ring 11, thereby controlling the locking state of the pan-tilt to ensure the stability of the pan-tilt during use and prevent rotation.

[0023] Through the arrangement of the rotating mechanism 5 capable of driving the threaded member 41 to rotate when the locking ring 11 rotates, the guide seat 42 guiding the threaded member 41 to move in the up and down direction when the threaded member 41 rotates, and the locking structure 6 capable of locking the pan-tilt main body 1 and the sphere 3 when the threaded member 41 presses downward, the pan-tilt ensures smooth rotation of the sphere 3 and sufficient locking force while having a compact structure, improving the user experience.

[0024] A sphere gasket 7 is provided between the pan-tilt main body 1 and the sphere 3. The locking structure 6 includes an elastic sheet 61 provided on the upper part of the sphere gasket 7 and arranged around the sphere 3. A locking member 62 capable of pressing and locking the sphere 3 by pressing the elastic sheet 61 when being pressed downward by the threaded member 41 is provided below the threaded member 41.

[0025] By adding a spherical washer 7 between the sphere 3 and the pan-tilt body 1, the direct contact between the two is reduced, wear is decreased, thus playing a buffering and protective role. The elastic piece 61 is arranged around the sphere 3. When the locking piece 62 is pressed downward by the threaded piece 41, the elastic piece 61 will be extruded and deformed, thereby increasing the frictional force on the sphere and achieving locking. Through the deformation of the elastic piece 61, the sphere 3 is prevented from spinning during use.

[0026] The locking piece 62 is a hollow cylindrical shape, and a locking inclined surface 621 capable of extruding the elastic piece 61 toward the sphere 3 is provided at the lower part of the locking piece 62.

[0027] The locking piece 62 is a hollow cylindrical structure. The locking inclined surface 621 is located at the lower part of the locking piece 62. When the threaded piece 41 presses downward, the locking inclined surface 621 will gradually extrude the elastic piece 61, causing the elastic piece 61 to apply pressure toward the sphere 3, thereby achieving the locking of the sphere 3. The setting of the locking inclined surface 621 makes the locking process more gradual, and the locking force can be gradually increased as needed.

[0028] The elastic piece 61 and the spherical washer 7 are of an integral structure, and a cut 71 for the deformation of the elastic piece 61 is provided on the spherical washer 7.

[0029] The integral design of the elastic piece 61 and the spherical washer 7 increases the strength and stability of the overall structure, reduces looseness and wear between components. The elastic piece 61 and the spherical washer 7 are an integral whole, making the contact locking between the contact surface of the elastic piece 61 and the sphere 3 smoother and improving the use feel. The elastic piece 61 and the spherical washer 7 do not require additional connecting parts, simplifying the assembly process and reducing the manufacturing cost. The cut 71 is provided on the spherical washer 7, and the cut 71 provides a space for the deformation of the elastic piece 61, thereby allowing the elastic piece 61 to undergo sufficient deformation when locking, ensuring that sufficient locking force can be provided when locking to fully squeeze the sphere 3 and improving the locking effect.

[0030] A locking ball 43 is provided at the lower part of the threaded piece 41, and a locking piece 622 for the locking ball 43 to press against is provided at the upper part of the locking piece 62.

[0031] A locking ball 43 is provided at the lower part of the threaded piece 41. When the threaded piece 41 moves downward, the locking ball 43 will press against the locking piece 622 on the locking piece 62, thereby achieving the locking of the sphere 3. The point contact between the locking ball 43 and the locking piece 62 can provide a higher locking force, while reducing the contact area and wear.

[0032] The locking structure 6 that can lock the two when the threaded part 41 presses downward can also be realized in other ways. For example, when the threaded part 41 presses downward, a set or multiple sets of jaws can be used to clamp the sphere 3 to achieve locking. Or a spring-loaded mechanism can be used to lock the sphere 3 and the pan-tilt body 1 through the spring when the threaded part 41 presses downward.

[0033] The locking ring 11 is sleeved on the pan-tilt body 1. The rotating mechanism 5 includes a gear ring 51 provided on the inner wall of the locking ring 11, a planet gear 52 meshed with the gear ring 51, and a sun gear 53 meshed with the planet gear 52. A clamping groove 531 is provided in the middle of the sun gear 53, and a clamping portion 411 matching the clamping groove 531 is provided on the threaded part 41.

[0034] The locking ring 11 is sleeved on the pan-tilt body 1. The gear ring 51 is provided on the inner wall of the locking ring 11 and meshes with the planet gear 52. The sun gear 53 meshes with the planet gear 52 and cooperates with the clamping portion 411 on the threaded part 41 through the clamping groove 531 in the middle thereof, so as to transmit the rotation to the threaded part 41. The planetary gear system can efficiently convert the rotation of the locking ring 11 into the rotation of the threaded part 41, with high stability and durability, and at the same time has a compact structure and small occupied space.

[0035] A sleeve 8 is sleeved outside the locking member 62. A limiting block 81 is provided at the bottom of the sleeve 8, and a limiting groove 72 matching the limiting block 81 is provided on the sphere washer 7.

[0036] The sleeve 8 is sleeved outside the locking member 62. The limiting block 81 is provided at the bottom of the sleeve 8 and cooperates with the limiting groove 72 on the sphere washer 7 to prevent the locking member 62 from shifting during the locking process.

[0037] A planetary gear carrier 54 is provided on the pan-tilt body 1. A rotating pin 55 connecting the two is provided between the planet gear 52 and the planetary gear carrier 54. A first notch 82 is provided at the upper part of the sleeve 8, and a second notch 12 is provided on the pan-tilt body 1 opposite to the first notch 82. The first notch 82 and the second notch 12 surround and form a pin slot 9 for one end of the rotating pin 55 to be inserted.

[0038] The planetary gear carrier 54 is provided on the pan-tilt body 1 for supporting and fixing the planet gear 52. The rotating pin 55 connects the planet gear 52 and the planetary gear carrier 54 to ensure that the planet gear can rotate freely. The first notch 82 is provided at the upper part of the sleeve 8, and the second notch 12 is provided on the pan-tilt body 1. The first notch 82 and the second notch 12 cooperate to form a pin slot 9 for one end of the rotating pin 55 to be inserted, ensuring that the rotating pin 55 can be firmly fixed between the pan-tilt body 1 and the sleeve 8. At this time, the positions of the planetary gear carrier 54, the planet gear 52, the sleeve 8, the pan-tilt body 1 and the sphere washer 7 are mutually restricted and fixed, and will not shake left and right, thus playing an anti-rotation role.

[0039] The rotation mechanism 5 that can drive the threaded member 41 to rotate when the locking ring 11 rotates can be implemented in other ways. For example, an electromagnetic device capable of driving the threaded member 41 to rotate is provided between the locking ring 11 and the threaded member 41. The electromagnetic device is activated by rotating the locking ring 11 to drive the threaded member 41 to rotate.

[0040] The pan-tilt base assembly 2 is provided with an installation groove 21 running through it, and the guide seat 42 is arranged in the installation groove 21.

[0041] The installation groove 21 runs through the pan-tilt base assembly 2, enabling the guide seat 42 to be embedded within the pan-tilt base assembly 2, saving space. By accommodating the guide seat 42 through the installation groove 21, it is convenient for the installation and adjustment of the guide seat 42, simplifying the assembly process.

[0042] The threaded member 41 is provided with a connecting rod 412, and the guide seat 42 is provided with a guide hole 421 for the connecting rod 412 to extend into. The outer wall of the connecting rod 412 is provided with a first thread, and the inner wall of the guide hole 421 is provided with a second thread that mates with the first thread.

[0043] The connecting rod 412 is arranged on the threaded member 41 and is used to cooperate with the guide hole 421 on the guide seat 42. The outer wall of the connecting rod 412 is provided with a first thread (not shown in the figure), and the inner wall of the guide hole 421 is provided with a second thread (not shown in the figure) that mates with it. The up and down movement of the threaded member 41 is achieved through the cooperation of the threads. Through the setting of the first thread and the second thread, the rotational motion of the threaded member 41 is converted into a linear motion, and the stability of the threaded member 41 during movement is ensured.

[0044] During use, the locking ring 11 is rotated, and the planetary gear system drives the planet gear 51 and the sun gear 53 to rotate, thereby driving the threaded member 41 to rotate, and guiding the threaded member 41 to move up and down through the guide seat 42. When locking, the threaded member 41 rotates downward, pushing the locking ball 43 to press down on the locking piece 622. The locking piece 622 pushes the locking member 62 to press the elastic piece 61, causing the elastic piece 61 to deform and squeeze towards the sphere 3, achieving the locking effect on the sphere 3.
