Description

Technical Field

[0001] The utility model relates to the technical field of photography auxiliary devices, in particular to an angle adjustment device and a photography kit. Background Art

[0002] As people's living standards improve, the demand for the use of gimbals is gradually increasing, especially when shooting telephoto or macro shots. Fine-adjustment gimbals are adopted by more and more photographers due to their advantage of fine-adjustable angles. Fine-adjustment gimbals on the market, such as the gear gimbal structure disclosed in the Chinese patent document with publication number CN207179090U, have a quick-release plate connecting piece vertically connected to the bottom of the clamping base. The driving mechanism formed by the cooperation of the worm gear and the worm drives the quick-release plate connecting piece to swing on the vertical plane with its bottom as the rotation center, thereby adjusting the shooting angle of the photographic equipment installed on the clamping base.

[0003] In order to prevent the quick-release plate connector from colliding with the head base during the swinging process, the gear head in the prior art usually has a long quick-release plate connector. This results in the clamp being installed at a high position, which makes its center of gravity higher and less stable.

[0004] Secondly, when the drive mechanism formed by the worm and worm wheel is installed on the gear head, its transmission method determines the installation method on the gear head. The direction of the worm must be consistent with the swing direction of the quick-release plate connector. Therefore, on some gear heads with integrated multiple angle adjustment functions, this drive method is subject to greater limitations, which is not conducive to the reasonable arrangement of the position of the drive mechanism according to the installation space. The appearance is also relatively abrupt and affects the photographer's experience. Utility Model Content

DETAILED DESCRIPTION

[0053] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes and are not intended to limit the present invention.

[0054] In the description of this application, the terms "upper" and "lower" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. These are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on this application.

[0055] For example 1, please refer to Figure 1 The utility model provides a technical solution: an angle adjustment device, comprising a hemispherical seat 1, wherein the top of the hemispherical seat 1 has a semi-concave ball groove 2, and further comprising a hemispherical body 3, wherein the hemispherical body 3 extends into the hemispherical seat 1, and the outer spherical surface of the hemispherical body 3 fits with the groove wall of the semi-concave ball groove 2, and the outer spherical surface of the hemispherical body 3 is in smooth contact with the groove wall of the semi-concave ball groove 2;

[0056] A strip hole A4 is provided through the bottom of the hemispherical seat 1 from top to bottom. The top opening of the strip hole A4 is connected to the semi-concave ball groove 2 so that the top opening of the strip hole A4 is arc-shaped. A transmission member A5 is vertically installed in the strip hole A4, and the transmission member A5 can move in the strip hole A4 under the action of external force.

[0057] See also Figure 1A through hole A31 is provided in the bottom center of the hemispherical body 3, and two stoppers 32 are provided at the bottom outlet of the through hole A31 along the length direction of the strip-shaped hole A4. The stoppers 32 are integrally formed with the hemispherical body 3.

[0058] The transmission member A5 includes a transmission block 51 located below the hemispherical seat 1. In this embodiment, the transmission block 51 is cylindrical in shape as a whole, and a driving portion 52 is integrally formed on the top of the transmission block 51. The upper end of the driving portion 52 extends into the through hole A31. When the transmission member A5 moves, the hemispherical body 3 can be swung along the arc direction of the strip hole A4 by the driving portion 52 to adjust the shooting angle of the photographic device. Compared with the swing adjustment mechanism in the prior art, the present invention can lower the center of gravity of the photographic device, making the shooting process more stable and safe, and reducing the overall volume of the pan / tilt head, which is convenient for storage and carrying. In addition, the stop block 32 can extend the effective distance of the driving portion 52, so that when the hemispherical body 3 swings a certain angle, the driving portion 52 will not separate from the hemispherical body 3.

[0059] The driving portion 52 has a curved surface 53 on one side facing the stopper 32 . The curved surface 53 can reduce the interference of the driving portion 52 on the movement of the stopper 32 when the hemispherical body 3 swings at a certain angle, so that the hemispherical body 3 can swing at a larger angle.

[0060] See also Figure 1 The driving mechanism A6 includes a screw rod 61 threadedly connected to the transmission block 51, and one end of the screw rod 61 is integrally formed with a mounting rod 62. An adjusting knob 63 is fixed to the end of the mounting rod 62. The mounting rod 62 is screwed by the adjusting knob 63. When the mounting rod 62 rotates, the screw rod 61 is driven to rotate synchronously, thereby driving the transmission block 51 to move along the length direction of the strip hole A4, and then the hemisphere 3 can be moved left or right along the arc direction of the strip hole A4 to fine-tune the photographic angle of the shooting equipment on the same vertical plane.

[0061] For example 2, please refer to Figures 2 to 4 , different from the first embodiment, the transmission block 51 of this embodiment is in the shape of a flat plate as a whole, and an oblique groove 54 is formed at the bottom of the transmission block 51. The oblique groove 54 is arranged diagonally along two diagonally opposite corners of the transmission block 51. The transmission member A5 also includes a rod body 55 extending into the oblique groove 54. The lower end of the rod body 55 is integrally formed with a sleeve 56. The sleeve 56 is threadedly connected to the screw rod 61 in the driving mechanism A6. Specifically:

[0062] The mounting rod 62 is screwed by the adjusting knob 63. When the mounting rod 62 rotates, the screw rod 61 is driven to rotate synchronously, thereby driving the sleeve 56 to move along the length direction of the screw rod 61. When the sleeve 56 moves, the rod body 55 moves in the inclined groove 54. Since the inclined groove 54 is obliquely arranged at the bottom of the transmission block 51, the transmission block 51 can be moved along the moving direction perpendicular to the sleeve 56 when the rod body 55 moves, thereby changing the direction of force propagation. At this time, the driving mechanism A6 can be arranged perpendicular to the movement direction of the transmission part A5 along the strip hole A4 or at a certain angle to the movement direction, which is conducive to the reasonable arrangement of the position of the driving mechanism A6 according to the installation space.

[0063] See also Figures 5 to 7 The present invention also provides a technical solution: a photographic kit including a gear head, the gear head including a head base 7 and a head axis A8 rotatably mounted on the head base 7. The rotational mounting method is conventional and will not be described in detail herein. The gear head also includes a head clamp 9. The angle adjustment device of the second embodiment is mounted between the head axis A8 and the head clamp 9. Since a plurality of angle adjustment mechanisms are often integrated on the gear, the angle adjustment device of the second embodiment can be used to reasonably arrange the position of the drive mechanism A6 according to the installation space on the gear head.

[0064] The pan / tilt clamp 9 is fixedly connected to the top of the hemisphere 3, and the hemisphere 3 has an upwardly opening mounting space 33, and a spherical gasket 10 is coupled and arranged in the mounting space 33, and the spherical surface of the spherical gasket 10 is in contact with the inner wall of the mounting space 33;

[0065] The top of the pan / tilt center axis A8 is provided with a mounting groove A81 for mounting the hemispherical seat 1. The hemispherical seat 1 and the hemispherical body 3 are both provided with strip-shaped positioning holes A11 extending therethrough. A positioning column A82 is integrally formed on the bottom wall of the mounting groove A81. The length of the positioning column A82 matches the length of the positioning hole A11 on the hemispherical seat 1, which is beneficial for positioning and mounting the hemispherical seat 1. The length of the positioning column A82 is less than the length of the positioning hole A11 on the hemispherical body 3, so that when the hemispherical body 3 swings in the hemispherical seat 1, the positioning column A82 cooperates with the positioning hole A11 to assist the movement of the hemispherical body 3.

[0066] The upper end of the positioning column A82 passes through the two positioning holes A11 in sequence and extends into the spherical gasket 10, and is fixed to the spherical gasket 10 with screws, thereby vertically connecting the gimbal center axis A8, the hemispherical seat 1 and the hemispherical body 3 into one, preventing the hemispherical seat 1 and the hemispherical body 3 from moving up and down.

[0067] See also Figure 7 and Figure 8 The bottom wall of the mounting groove A81 is provided with a movable groove 83 for sliding the transmission member A5, and the lower portion of the movable groove 83 is connected to a mounting long hole 13 for mounting the drive mechanism A6;

[0068] The mounting slot 13 includes four mounting holes that are sequentially connected from the inside to the outside. A first bearing 14 is installed in the mounting hole A131. The first bearing 14 is installed at the end of the screw rod 61 away from the mounting rod 62.

[0069] The mounting hole B132 is used to mount the sleeve 56. The second bearing 15 is mounted in the mounting hole C133. The second bearing 15 is sleeved outside the mounting rod 62. The first bearing 14 and the second bearing 15 are both plane thrust bearings, which can reduce the axial load generated when the screw 61 is turned, making the operation smoother.

[0070] A stop ring 16 is threadedly connected in the mounting hole D134. The stop ring 16 is sleeved on the outside of the mounting rod 62 and is located in front of the adjusting knob 63. The stop ring 16 can play a limiting role to prevent the screw rod 61 from axial movement in the mounting long hole 13. The end of the mounting rod 62 is threadedly connected to a screw 17 for connecting the adjusting knob 63 and the mounting rod 62 as one.

[0071] The working principle of the present utility model is as follows: when the mounting rod 62 is screwed clockwise / counterclockwise by the adjusting knob 63, the rotation of the mounting rod 62 drives the screw rod 61 to rotate synchronously, thereby driving the sleeve 56 to move along the length direction of the screw rod 61. When the sleeve 56 moves, the rod body 55 moves in the inclined groove 54. Since the inclined groove 54 is obliquely arranged at the bottom of the transmission block 51, the transmission block 51 can be moved along the length direction of the movable groove 83 when the rod body 55 moves. When the transmission block 51 moves, the driving part 52 and the stop block 32 cooperate to move the hemisphere 3 to swing left or right along the arc direction of the strip hole A4, thereby accurately fine-tuning the photographic angle of the shooting equipment on the same vertical plane.

[0072] See also Figure 9The present invention also provides another technical solution: a photography kit, including a two-dimensional fine-tuning pan-tilt platform 18, the bottom of which is generally cylindrical, and the two-dimensional fine-tuning pan-tilt platform 18 adopts the angle adjustment device described in Example 1, and a clamp is installed on the top of the device to achieve the purpose of reducing the volume of the two-dimensional fine-tuning pan-tilt platform 18 and accurately fine-tuning the photographic angle of the shooting equipment.

[0073] See also Figures 10 to 15 The present invention also provides another technical solution: a photographic kit, including a three-dimensional fine-tuning pan-tilt head 19, wherein the three-dimensional fine-tuning pan-tilt head 19 includes a pan-tilt head axis B20, wherein the pan-tilt head axis B20 is cylindrical in shape as a whole, and the angle adjustment device in the first embodiment is installed on the top of the pan-tilt head axis B20, and a clamping seat is installed on the top of the device. Since the three-dimensional fine-tuning pan-tilt head 19 has fewer integrated components, the angle adjustment device in the first embodiment can be directly adopted. Of course, the angle adjustment device in the second embodiment can also be adopted as needed to achieve the effect of reasonably arranging the driving mechanism A6 according to the installation space. The bottom of the pan-tilt head axis B20 has a mounting groove B21, and an arched member 22 is installed in the mounting groove B21;

[0074] The bottom end surface of the pan / tilt center axis B20 is provided with two arc-shaped grooves A23 facing each other, and the bottom surface of the arched member 22 is provided with an arc-shaped groove B24. The two ends of the arc-shaped groove B24 are respectively aligned with the two arc-shaped grooves A23, and an arched support 25 is coupled to the arc-shaped groove A23 and the arc-shaped groove B24.

[0075] The arched support 25 has an arched inner cavity 30, in which an arched gasket 31 is coupled. Positioning holes B32 are respectively provided on the arched member 22 and the arched support 25 in an upward and downward manner. The bottom wall of the mounting groove B21 protrudes downward to form a positioning column B33. The width of the positioning column B33 is adapted to the positioning hole B32. The length of the positioning column B33 is adapted to the length of the positioning hole B32 on the arched member 22, which is conducive to the positioning and installation of the arched member 22. The length of the positioning column B33 is less than the length of the positioning hole B32 on the arched support 25, leaving room for movement for the mutual swing of the pan / tilt center axis B20 and the arched support 25.

[0076] The positioning column B33 passes through the two positioning holes B32 in sequence downward and extends into the arched inner cavity 30, and is fixedly connected to the arched gasket 31 by screws, thereby vertically connecting the pan head axis B20, the arched member 22 and the arched support 25 into one. The bottom opening of the arched inner cavity 30 is fixedly connected to a bottom plate 34 by screws to seal the bottom opening of the arched inner cavity 30;

[0077] A strip hole B26 is provided in the middle of the arch member 22 from top to bottom, and a through hole B27 is provided on the top of the arch support 25. A transmission member B28 is provided in both the through hole B27 and the strip hole B26. The portion of the transmission member B28 extending into the through hole B27 is in the shape of a round handle. The other end of the transmission member B28 is connected to a driving mechanism B29 for driving the transmission member B28 to move along the length direction of the strip hole B26 to drive the arch support 25 and the arch member 22 to swing relative to each other. The driving mechanism B29 can adopt the driving mechanism A6 in Example 1. The installation method of the driving mechanism B29 on the three-dimensional fine-tuning pan-tilt platform 19 is the same as the installation direction of the driving mechanism A6 on the gear pan-tilt platform.

[0078] When the driving mechanism B29 drives the transmission member B28 to move linearly, the transmission member B28 drives the arch support 25 to swing along the arc direction of the arc groove B24. However, since the arch support 25 is fixedly mounted on the clamping base of the tripod during use, the arch support 25 does not swing, and the pan head axis B20 swings on the arch support 25, thereby driving the pan head axis B20 to swing within a certain range to fine-tune the photographic angle of the shooting device. The final state is as follows: Figure 15 As shown;

[0079] Secondly, if Figures 10 to 12 As shown, the arrangement direction of the driving mechanism B29 can be perpendicular to the arrangement direction of the driving mechanism A6 in the angle adjustment device on the top of the gimbal center axis B20, so that the angle of the clamp can be accurately fine-tuned in two intersecting vertical planes, and the bottom surface of the arch support 25 is cylindrical, with a relatively large bearing area and a stable structure. At the same time, the three-dimensional fine-tuning gimbal 19 adopts the angle adjustment device in Example 1, which can achieve the purpose of reducing the volume of the three-dimensional fine-tuning gimbal 19 and accurately fine-tuning the photographic angle of the shooting equipment.

[0080] Finally, it should be noted that the above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
