Description

Technical Field

[0001] The invention relates to the technical field of photography auxiliary devices, and in particular to a gear head capable of quickly adjusting angles. Background Art

[0002] The gear head is a relatively sophisticated auxiliary equipment among camera heads, and has incomparable advantages when used in telephoto or macro photography. However, since it takes a long time for the gear head to horizontally adjust the angle of the clamp seat through a fine-tuning mechanism (the worm and worm gear cooperate), it is less efficient when the horizontal photographic angle of the shooting equipment needs to be quickly adjusted. Therefore, how to provide a gear head with the function of fine-tuning and quickly adjusting the horizontal angle of the clamp seat is a problem that needs to be urgently solved by technical personnel in this field. Summary of the invention

[0003] In view of this, an object of the present invention is to provide a gear pan-tilt platform that can quickly adjust the angle, which has integrated fine-tuning and quick-adjusting functions, and has a simple structure and a compact size, so as to solve the technical problems described in the background technology.

[0004] The present invention is achieved through the following technical solutions:

[0005] A gear pan / tilt capable of quickly adjusting an angle, comprising a clamping seat with an accommodating cavity, the opening of the accommodating cavity facing downward, a bottom plate installed in the bottom opening of the accommodating cavity, a rotation adjustment seat arranged below the bottom plate, a limiting groove arranged on one side of the bottom plate facing the rotation adjustment seat, and a button installed on the rotation adjustment seat for cooperating with the limiting groove to limit the free rotation of the bottom plate;

[0006] The bottom plate is provided with a fine-tuning mechanism for driving the clamping seat and the rotation adjustment seat to rotate relative to each other so as to adjust the horizontal angle of the clamping seat.

[0007] Furthermore, a central shaft is fixedly connected to the center of the bottom plate, and the upper end of the central shaft extends into the clamp seat and is connected to the clamp seat as a whole through a connecting screw A;

[0008] The lower end of the central shaft extends downwardly out of the bottom plate, and a damping gasket is arranged between the bottom plate and the rotation adjustment seat and at the bottom of the rotation adjustment seat. A positioning buckle that is mutually plugged with the lower end of the central shaft is installed in the damping gasket located below, and when the central shaft rotates, the positioning buckle can be driven to rotate synchronously;

[0009] A connecting screw B is installed at the bottom of the rotating adjustment seat, and the screw portion of the connecting screw B passes upward through the positioning buckle and is threadedly connected to the lower end of the central shaft to connect the positioning buckle and the central shaft as a whole.

[0010] Furthermore, the fine-tuning mechanism includes a worm gear integrally formed in the middle part of the central axis, and the clamp seat is provided with an installation space connected to the accommodating cavity. The installation space is connected to the accommodating cavity, and a driving shaft for driving the worm gear to rotate is installed in the installation space, and both ends of the driving shaft extend out of the installation space respectively, and knobs are respectively installed at the ends.

[0011] Further, the driving shaft comprises a worm meshing with the worm wheel, and mounting rods are integrally formed at both ends of the worm;

[0012] Stop rings are respectively inserted at the openings at both ends of the installation space. The stop rings are fixedly connected to the knobs and are sleeved outside the installation rods. Insert blocks for limiting the movement of the stop rings are installed on the installation rods.

[0013] Furthermore, a plurality of positioning holes are provided at the bottom of the base plate along its rotation direction; a mounting hole is provided on the side of the rotation adjustment seat facing the base plate, a spring A is vertically fixed in the mounting hole, a positioning bead is fixed on the spring A, and the positioning bead partially extends into the positioning hole under the action of the spring A.

[0014] Furthermore, the limiting groove includes a circular arc groove and a plurality of arc grooves arranged along the arc direction of the circular arc groove and connected to the circular arc groove;

[0015] The button comprises a pressing portion and a limiting portion integrally formed on the top of the pressing portion, and when the limiting portion extends into the arc groove, the base plate can be restricted from freely rotating.

[0016] Furthermore, a notch is provided on the bottom end surface of the rotation adjustment seat, the pressing portion is installed in the notch, and a spring B is installed between the front end surface of the pressing portion and the rotation adjustment seat;

[0017] A strip hole communicating with the notch is provided on the top end surface of the rotation adjustment seat, and the limiting portion passes through the strip hole and extends into the limiting groove.

[0018] Furthermore, a hemispherical body is fixedly disposed outside the rotation adjustment seat, and a through hole is opened on the hemispherical body for allowing the pressing part to extend outward.

[0019] The beneficial effects of the present invention are:

[0020] 1. When the camera angle of the photographic device needs to be quickly adjusted, the button is pressed to disengage the button from the limiting groove to release the circumferential limit on the bottom plate. After the limit is released, the clamping seat is rotated, and the clamping seat drives the bottom plate and the rotating adjustment seat to rotate relative to each other, thereby quickly adjusting the shooting angle of the photographic device;

[0021] After the adjustment is completed, the button cooperates with the limiting groove to limit the free rotation of the base plate, thereby quickly locking the clamping seat.

[0022] 2. When the clamp seat rotates, the central axis is driven to rotate synchronously, and the rotation of the central axis drives the base plate and the positioning buckle to rotate synchronously. When the positioning buckle and the base plate rotate synchronously, the damping gasket between the base plate and the rotation adjustment seat and the damping gasket between the rotation adjustment seat and the positioning buckle generate damping force to prevent the base plate from rotating excessively, thereby stably and quickly adjusting the shooting angle of the photographic equipment.

[0023] 3. When the base plate rotates, the positioning bead is squeezed downward into the mounting hole. When the base plate continues to rotate so that the positioning bead is aligned with the positioning hole at the bottom of the base plate, the positioning bead extends out of the mounting hole and into the positioning hole under the action of the spring A, thereby colliding to produce a prompt sound and a positioning effect during the rotation of the base plate, so that the rotation angle of the clamp seat can be clearly known in conjunction with the scale marking outside the hemisphere, and it has a mechanical feel, thereby improving the user experience.

[0024] 4. When it is necessary to fine-tune the shooting angle of the photographic equipment, directly turn the knob to drive the worm to rotate, and the rotation of the worm drives the worm wheel to rotate, and the rotation of the worm wheel drives the central axis to rotate, thereby driving the base plate and the clamp to rotate synchronously to accurately fine-tune the shooting angle of the photographic equipment.

[0034] 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 changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0035] In the description of the present application, the terms "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present 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, and therefore should not be understood as a limitation on the present application.

[0036] See also Figures 1 to 5 The present invention provides a technical solution: a gear pan / tilt capable of quickly adjusting an angle, comprising a clamping seat 1 having an accommodating cavity 2, the opening of the accommodating cavity 2 facing downward, a bottom plate 3 installed in the bottom opening of the accommodating cavity 2, a central axis 8 fixedly connected to the center of the bottom plate 3, an upper end of the central axis 8 extending into the clamping seat 1, and connected to the clamping seat 1 by connecting screws A9;

[0037] The lower end of the central shaft 8 extends downward from the bottom plate 3, a rotation adjustment seat 4 is arranged below the bottom plate 3, a damping gasket 10 is arranged between the bottom plate 3 and the rotation adjustment seat 4 and at the bottom of the rotation adjustment seat 4, a positioning buckle 11 mutually plugged with the lower end of the central shaft 8 is installed in the damping gasket 10 located below, and when the central shaft 8 rotates, the positioning buckle 11 can be driven to rotate synchronously;

[0038] A connecting screw B12 is installed at the bottom of the rotating adjustment seat 4, and the screw portion of the connecting screw B12 passes upward through the positioning buckle 11 and is threadedly connected to the lower end of the central shaft 8, so as to connect the positioning buckle 11 and the central shaft 8 as a whole;

[0039] When the clamping seat 1 is rotated to quickly adjust the shooting angle of the photographic equipment, the clamping seat 1 is rotated to drive the central axis 8 to rotate. When the central axis 8 rotates, it drives the base plate 3 and the positioning buckle 11 to rotate synchronously. When the positioning buckle 11 and the base plate 3 rotate synchronously, the damping gasket 10 between the base plate 3 and the rotation adjustment seat 4 and the damping gasket 10 between the rotation adjustment seat 4 and the positioning buckle 11 generate damping force to prevent the base plate 3 from excessive rotation, which is beneficial to the stable rotation of the clamping seat 1 to adjust the shooting angle of the photographic equipment. The locking force can be adjusted by screwing the connecting screw B12, and then the magnitude of the damping force generated by the damping gasket 10 is adjusted.

[0040] See also Figure 1 , Figure 3 , Figure 5 and Figure 6 The bottom plate 3 is provided with a limiting groove 5 on one side facing the rotating adjustment seat 4, and the limiting groove 5 includes an arc groove 51 and a plurality of arc grooves 52 arranged along the arc direction of the arc groove 51 and connected to the arc groove 51;

[0041] The rotation adjustment seat 4 is provided with a button 6 for cooperating with the limiting groove 5 to limit the free rotation of the bottom plate 3. The button 6 includes a pressing portion 61 and a limiting portion 62 integrally formed on the top of the pressing portion 61. When the limiting portion 62 extends into the arc groove 52, the bottom plate 3 can be limited from free rotation.

[0042] The bottom end surface of the rotation adjustment seat 4 has a notch 17, the pressing portion 61 is installed in the notch 17, and a spring B19 is installed between the front end surface of the pressing portion 61 and the rotation adjustment seat 4;

[0043] A strip hole 18 communicating with the notch 17 is formed on the top end surface of the rotation adjustment seat 4, and the limiting portion 62 passes through the strip hole 18 and extends into the limiting groove 5;

[0044] A hemisphere 20 is fixedly provided on the outside of the rotation adjustment seat 4, and a through hole 21 is opened on the hemisphere 20 for the pressing part 61 to extend outward. The hemisphere 20 is fixedly connected to the pan-tilt base, or the rotation adjustment seat 4 can also be directly fixed on the pan-tilt base, and the pressing part 61 is pressed into the through hole 21. When the pressing part 61 moves, it drives the limiting part 62 to slide along the strip hole 18, so that the top of the limiting part 62 moves from the arc groove 52 to the circular arc groove 51. At this time, the limiting part 62 releases the limit on the bottom plate 3, and the bottom plate 3 can rotate freely. When the button 6 is released, the button 6 is reset under the action of the spring B19, and the limiting part 62 moves back into the arc groove 52 to limit the free rotation of the bottom plate 3.

[0045] See also Figure 5 and Figure 6 A plurality of positioning holes 13 are provided at the bottom of the base plate 3 along its rotation direction, and the plurality of positioning holes 13 are arranged in an arc on the base plate 3; a mounting hole 14 is provided on the side of the rotation adjustment seat 4 facing the base plate 3, and a spring A15 is vertically fixed in the mounting hole 14, and a positioning bead 16 is fixed on the spring A15, and the positioning bead 16 partially extends into the positioning hole 13 under the action of the spring A15. Specifically, when the base plate 3 rotates, the positioning bead 16 can be squeezed downward into the mounting hole 14. When the base plate 3 continues to rotate so that the positioning bead 16 is aligned with the positioning hole 13 at the bottom of the base plate 3, the positioning bead 16 extends out of the mounting hole 14 and into the positioning hole 13 under the action of the spring A15, thereby colliding to produce a prompt sound and a positioning effect during the rotation of the base plate 3, so that the rotation angle of the clamp 1 can be clearly known in conjunction with the scale marking outside the hemisphere 20, and it has a mechanical feel, thereby improving the user experience.

[0046] See also Figures 1 to 4, a fine-tuning mechanism 7 is installed above the bottom plate 3 for driving the clamping seat 1 and the rotating adjustment seat 4 to slowly rotate relative to each other so as to accurately adjust the horizontal angle of the clamping seat 1, the fine-tuning mechanism 7 includes a worm gear 71 integrally formed in the middle of the central axis 8, the worm gear 71 is a one-third worm gear 71, the accommodating chamber 2 includes a mounting groove for installing the worm gear 7, the top of the worm gear 71 extends into the mounting groove and is adapted to the shape of the mounting groove, when the clamping seat 1 rotates, the worm gear 71 can be driven to rotate synchronously, the clamping seat 1 is provided with an installation space 72 connected with the accommodating chamber 2, the installation space 72 is connected with the accommodating chamber 2, and a driving shaft 73 for driving the worm gear 71 to rotate is installed in the installation space 72, both ends of the driving shaft 73 extend out of the installation space 72 respectively, and knobs 74 are installed at the ends thereof;

[0047] When the driving shaft 73 is rotated by the knob 74, the driving shaft 73 drives the worm gear 71 to rotate, and the rotation of the worm gear 71 drives the central shaft 8 to rotate. The rotation of the central shaft 8 drives the base plate 3 and the clamp 1 to rotate synchronously, so that the shooting angle of the photographic equipment can be accurately fine-tuned within a certain range.

[0048] See also Figure 2 and Figure 3 The driving shaft 73 includes a worm 731 meshing with the worm wheel 71, and mounting rods 732 are formed integrally at both ends of the worm 731. Two planar thrust bearings are mounted on the mounting rods 732. The two planar thrust bearings are disposed at both ends of the worm 731. The planar thrust bearings are used to bear axial loads to provide rolling or sliding contact, which significantly reduces the friction caused by the axial load during the process of driving the worm 731 to rotate through the knob 74, and helps to improve the efficiency and user experience of the system;

[0049] Stop rings 75 are respectively inserted at the openings at both ends of the installation space 72. The stop rings 75 are fixedly connected to the knob 74 and are mounted on the outside of the installation rod 732. An insert block 76 for limiting the movement of the stop ring 75 is installed on the installation rod 732. The insert block 76 threadedly connects the stop ring 75 and the installation rod 732 to connect the stop ring 75 and the installation rod 732 as a whole, so that rotating the knob 74 can drive the installation rod 732 to drive the worm 731 to rotate, and the knobs 74 and the stop rings 75 at both ends cooperate to prevent the drive shaft 73 from axial movement.

[0050] The working principle of the present invention is as follows: when it is necessary to quickly adjust the shooting angle of the photographic device, the pressing portion 61 is pressed into the through hole 21, and when the pressing portion 61 moves, it drives the limiting portion 62 to slide along the strip hole 18, so that the top of the limiting portion 62 moves from the arc groove 52 to the circular arc groove 51, and at this time, the limiting portion 62 releases the circumferential limit on the bottom plate 3;

[0051] After releasing the limit, the clamping seat 1 is rotated, and when the clamping seat 1 rotates, the central shaft 8 is driven to rotate synchronously, and when the central shaft 8 rotates, the bottom plate 3 and the positioning buckle 11 are driven to rotate synchronously, and when the positioning buckle 11 and the bottom plate 3 rotate synchronously, the damping gasket 10 between the bottom plate 3 and the rotation adjustment seat 4 and the damping gasket 10 between the rotation adjustment seat 4 and the positioning buckle 11 generate a damping force to prevent the bottom plate 3 from rotating excessively, thereby stably and quickly adjusting the shooting angle of the photographic device;

[0052] After the adjustment is completed, the button 6 is released, and the button 6 is reset under the action of the spring B19. At this time, the limiting portion 62 moves back into the arc groove 52 to limit the free rotation of the bottom plate 3, thereby completing the locking of the horizontal shooting angle of the photographic device.

[0053] When the base plate 3 rotates, the positioning bead 16 is squeezed downward into the mounting hole 14. When the base plate 3 continues to rotate so that the positioning bead 16 is aligned with the positioning hole 13 at the bottom of the base plate 3, the positioning bead 16 extends out of the mounting hole 14 and into the positioning hole 13 under the action of the spring A15, thereby colliding to produce a prompt sound and a positioning effect during the rotation of the base plate 3, so that the rotation angle of the clamp 1 can be clearly known in conjunction with the scale marking outside the hemisphere 20, and it has a mechanical feel, thereby improving the user experience.

[0054] When the camera angle of the photographic device needs to be fine-tuned, the knob is turned to drive the worm 731 to rotate, and the rotation of the worm 731 drives the worm wheel 71 to rotate, and the rotation of the worm wheel 71 drives the central shaft 8 to rotate, thereby driving the bottom plate 3 and the clamping seat 1 to rotate synchronously, so as to accurately fine-tune the shooting angle of the photographic device;

[0055] In the process of accurately fine-tuning the shooting angle of the photographic equipment through the fine-tuning mechanism 7, since the base plate 3 will rotate synchronously with the worm gear 71 under the drive of the worm gear 71, and the groove wall of the limiting groove 5 is arc-shaped, and the limiting portion 62 is cylindrical, when the base plate 3 rotates under the action of the fine-tuning mechanism 7, the limiting portion 62 can be squeezed and pushed from the arc groove 52 into the circular arc groove 51, and the limiting portion 62 can move along the groove wall of the limiting groove 5, so that the button 6 will not interfere with the use of the fine-tuning mechanism 7.

[0056] 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 substitutions made by technicians in this field on the basis of the present invention are within the scope of protection required by the present invention.
