[0038] This application proposes a pan / tilt head for photography and videography, suitable for use with photography and videography equipment. Photographic equipment is a general term for cameras, lenses, related accessories, and various other equipment and items related to photography. Consumables such as film, as well as photography vests and bags sold by most photography equipment dealers, fall under the category of photographic equipment, also known as photographic accessories. The scope of photographic equipment is broad. In addition to the familiar cameras, it primarily includes various zoom lenses, fixed-focus lenses, flashes, color filters for various purposes, camera bags, camera tripods, studio flashes, softboxes, various light stands, reflectors, reflective umbrellas, outdoor lights, video lights, quartz lamps, lens caps, lens hoods, tripods, adapters, expansion boards, quick-release components, brackets, monopods, camera cleaning tools, shutter cables, and accessories for the aforementioned equipment. Traditional photographic equipment also includes darkroom printers, enlargers, safelights, laminators, thermostats, timers, and the like. Color enlargers and printers also fall under the category of photographic equipment. Digital cameras have integrated photography and videography into one, so they are also called more extensive imaging equipment, which includes both photography and videography.

[0039] In a first embodiment, as shown in Figures 1, 2, and 9, a photographic and video camera head includes at least one locking assembly, a support frame 4, a base bracket 5 rotatably connected to the support frame 4, and a handle assembly 6 for adjusting the pitch angle of the support frame 4. The support frame 4 is used to support photographic and video equipment. The base bracket 5 includes a base 51 for externally connecting photographic and video equipment, and an upper support portion 52 rotatably connected to the support frame 4. A locking assembly is located between the support frame 4 and the upper support portion 52 to lock or unlock the support frame 4, so that the support frame 4 can rotate about a first axis to drive the photographic and video equipment to perform pitch motion.

[0040] Among them, the upper support portion 52 is protruding with a first rotating shaft 42 extending along the first axis, wherein a locking assembly is used to clamp the first rotating shaft 42, and the locking assembly includes a rotating part, at least one clamping part 11 and at least one elastic part 12, the elastic part 12 is used to push the clamping part 11 to clamp on the outer peripheral surface of the first rotating shaft 42, an elastic part 12 is used to push a clamping part 11, and the rotating part rotates to drive the clamping part 11 to release the first rotating shaft 42.

[0041] In this embodiment, after assembly, all elastic members 12 push all clamping members 11 to clamp and lock the first rotating shaft 42. When the rotating member is driven manually or by other driving structures, the clamping member 11 connected to the rotating member is driven to release the first rotating shaft 42, thereby unlocking the first rotating shaft 42. The handle assembly 6 can be moved to adjust the rotation angle of the support frame 4 relative to the upper support part 52, thereby adjusting the photographic equipment, such as the pitch angle of the camera. After that, after releasing or stopping the actuation of the rotating member, the elastic member 12 pushes the clamping member 11 to reset to lock the first rotating shaft 42 again. The first rotating shaft 42 extends in the horizontal direction, the clamping is stable, and it is easy to operate.

[0042] Among them, the number of locking components is set according to the needs of use, and the number of rotating parts can be 1, 2 or more than 2. One rotating part can drive a clamping part 11, and the clamping part 11 and the side wall where the first rotating shaft 42 is located form a clamping or release to lock or unlock the first rotating shaft 42. In order to ensure stable clamping, one rotating part can also drive two clamping parts 11, and the two clamping parts 11 are clamped on the outer periphery of a rotating shaft. The number of rotating parts and clamping parts 11 is set according to needs. For example, if there are two rotating parts, one rotating part drives two clamping parts 11, thereby driving the two rotating parts to realize that four clamping parts 11 can synchronously clamp the first rotating shaft 42, or synchronously release the first rotating shaft 42.

[0043] In this embodiment, referring to Figures 8 to 10, in order to make the locking assembly compact and easy to install, the support frame 4 is provided with at least one long strip slide 41 on the side away from the upper support portion 52, the outer peripheral surface of the first rotating shaft 42 extends into the slide 41, the clamping member 11 and the elastic member 12 are both installed in the slide 41, one end of the elastic member 12 is connected to the clamping member 11, and the other end is connected to the side groove wall at one end of the slide 41, the rotating member is provided with a convex limiting portion, the limiting portion extends into the slide 41 and abuts against the clamping member 11. A side away from the elastic member 12 allows the clamping member 11 to clamp the first rotating shaft 42. After assembly, the side of the clamping member 11 located between the elastic member 12 and the limiting portion supports the first rotating shaft 42. When the rotating member rotates to drive the limiting portion to push the clamping member 11 to slide in the slide groove 41, the clamping member 11 releases the first rotating shaft 42. An elastic member 12 and a clamping member 11 can be provided in a slide groove 41, and adjacent slide grooves 41 can also be connected. According to the aspects of saving space and facilitating production, the elastic member 12 can be a long strip spring.

[0044] In this embodiment, in order to facilitate the operation of the rotating part, the rotating part includes an annular portion and a lug portion. The lug portion is protruded from the outer side of the annular portion. A through hole is provided in the middle of the annular portion for rotatably accommodating the first rotating shaft 42. At least one limiting portion is protruded from one surface of the annular portion. When the lug portion is actuated, the annular portion drives the limiting portion to push the clamping member 11 to move. It can be actuated manually or by other structures.

[0045] Preferably, the annular portion is convexly provided with two limiting portions distributed around the through hole, one limiting portion matches a clamping member 11 and an elastic member 12 , and the support frame 4 is concavely provided with two sliding grooves 41 .

[0046] Specifically, referring to Figures 8 to 10 again, the locking assembly includes two rotating parts, namely the first rotating part 2 and the second rotating part 3, the first rotating part 2 includes a first annular portion 22 and a first lug portion 23, the first annular portion 22 is provided with a first through hole in the middle, and one surface of the first annular portion 22 is provided with at least one first limiting portion 21, the second rotating part 3 includes a second annular portion 32 and a second lug portion 33, the second annular portion 32 is provided with a second through hole in the middle, and one surface of the second annular portion 32 is convexly provided with at least one second limiting portion 31, the first annular portion 22 is provided with an arc groove 24 matching the number of the second limiting portions 31, one end of the second limiting portion 31 passes through the arc groove 24, a first limiting portion 21 limits a rotating part to extrude an elastic part 12 at one end of a sliding groove 41, and a second limiting portion 31 limits a rotating part to extrude an elastic part 12 at the other end of the sliding groove 41, saving space and convenient operation. The relative positions of the first rotating part 2 and the second rotating part 3 are not easily changed, and the operation is stable.

[0047] After assembly, a first limiting portion 21 abuts against a clamping member 11, and a second limiting portion 31 abuts against another clamping member 11. By rotating the first lug portion 23 and the second lug portion 33, the first lug portion 23 and the second lug portion 33 can be rotated around the first rotating shaft 42 in opposite rotation directions, so that the first limiting portion 21 and the second limiting portion 31 can slide toward the two ends of the sliding groove 41. For example, the first lug portion 23 rotates clockwise and the second lug portion 33 rotates counterclockwise, so that four or more clamping members 11 release the first rotating shaft 42 at the same time.

[0048] Further, referring to Figure 9, there are four slide grooves 41, one slide groove 41 accommodates an elastic member 12, a rotating member and a first limit portion 21, or one slide groove 41 accommodates an elastic member 12, a rotating member and a second limit portion 31, and the two slide grooves 41 are connected to each other, saving space and facilitating production.

[0049] In this embodiment, the limiting portion can be in the shape of a curved plate. The connection between the elastic member 12 and the clamping member 11 can be fixed, abutted, or removable, without limitation. The elastic member 12 can be a spring, such as a compression spring or a tension spring. The first lug portion 23 can be flat. In other embodiments, the two slide grooves 41 may not be interconnected. The base 51 can be circular with a threaded hole in the center.

[0050] Furthermore, in order to facilitate the control and adjustment of the rotating part, the pan-tilt head also includes an unlocking part 13, which drives the first lug part 23 and the second lug part 33 to move. The unlocking part 13 includes an unlocking part, which is clamped between the first lug part 23 and the second lug part 33. When the unlocking part 13 rotates along the first direction, it drives the unlocking part to push the first lug part 23 and the second lug part 33 to separate in opposite directions. The unlocking part changes the width of the part clamped between the first lug part 23 and the second lug part 33 to adjust the distance between the first lug part 23 and the second lug part 33 to drive the first lug part 23 and the second lug part 33 to rotate. The unlocking part is asymmetrically arranged and can be threadedly connected to the support frame 4. In order to facilitate adjustment, the sliding unlocking part is clamped between the first lug part 23 and the second lug part 33, and the cross-section is a spherical shape with flat or inclined surfaces on both sides, which is not limited here. The unlocking member 13 is located on the outer surface of the support frame 4 away from the upper support part 52 for easy operation. There is a rotation installation position between the support frame 4 and the upper support part 52, such as a circular boss and a mounting groove that are matched and installed. The specific details are not described in detail.

[0051] Of course, it can be understood that the first lug portion 23 and the second lug portion 33 are respectively extended out of the pan-tilt head, and the first lug portion 23 and the second lug portion 33 are directly moved manually to move in the opposite directions, releasing the first lug portion 23 and the second lug portion 33. The elastic member 12 can push the clamping member 11 to reset, and the clamping member 11 pushes the first limiting portion 21 and the second limiting portion 31 to reset, thereby resetting the first lug portion 23 and the second lug portion 33.

[0052] In some embodiments, the annular portion may also not be provided with a lug, and the side of the annular portion is recessed to form a limiting groove 34. The first annular portion 22 and the second annular portion 32 both have side recesses to form a limiting groove 34. The two limiting grooves 34 are connected to each other from top to bottom, and the unlocking portion passes through and is clamped in the two limiting grooves 34. The groove walls on both sides of the two limiting grooves 34 clamp the two sides of the unlocking portion. When the unlocking member 13 rotates along the first direction, it drives the unlocking portion to push the groove walls on both sides of the two limiting grooves 34 to separate in reverse.

[0053] Further, referring to Figures 8 to 10, the base bracket 5 includes two upper support parts 52. The lower end of the base 51 is used to support external photographic and video equipment. The upper end of the base 51 has two upper support parts 52 spaced apart. The two support frames 4 are rotatably connected to the two upper support parts 52 respectively. The handle assembly 6 is located on one of the support frames 4. The other support frame 4 and the other upper support part 52 can be easily adjusted by providing a damping assembly, such as a torsion spring. The handle assembly 6 can be switched to connect with both support frames 4 to meet the needs of left-handed and right-handed shooting. The upper ends of the two support frames 4 can be provided with a clamping assembly, such as a slide seat and a quick-release plate. The quick-release plate is provided with a camera or other electronic device. Of course, in order to make the support frame 4 rotate slowly, the support frame 4 and the upper support part 52 can also be provided with a torsion spring 7.

[0054] To facilitate assembly, the first rotating shaft 42 includes a fixed section and a clamping section. The fixed section is fixedly connected to the upper support portion 52 and can also be arranged as an integral unit. The clamping section and the fixed section are detachably connected and are used to clamp, lock or release the clamped part 11. The fixed section and the clamping section rotate synchronously. In order to prevent relative movement between the two during rotation, a limiting structure can be provided between the two, such as a concave-convex structure, a limiting groove 34 and a plane structure, a limiting pin, etc. The diameters of the fixed section and the clamping section can be different and can be designed according to specific needs. For example, the clamping section is mushroom-shaped, and the diameter increase portion passes through the first through hole and the second through hole. In order to further lock and fix, the fixed section and the clamping section can be locked together by screws.

[0055] When the first rotating shaft 42 is unlocked, the unlocking member 13 is rotated so that the portion of the unlocking member located between the first and second lugs 23 and 33 increases, thereby driving the first and second lugs 23 and 33 to separate in opposite directions. When the first lug 23 rotates to drive the first annular portion 22 to rotate, the first limiting portion 21 pushes one clamping member 11 to slide. When the second lug 33 rotates to drive the second annular portion 32 to rotate, the second limiting portion 31 pushes another clamping member 11 to slide. All elastic members 12 are compressed, thereby releasing all clamping members 11 from the first rotating shaft 42. The user can then move the handle assembly 6 to adjust the rotation angle of the support frame 4 relative to the first rotating shaft 42, thereby adjusting the pitch angle of the camera, that is, adjusting the shooting angle of electronic products such as cameras.

[0056] After adjustment, when the unlocking portion is rotated in the opposite direction, the width of the unlocking portion between the first lug portion 23 and the second lug portion 33 is reduced, and all elastic members 12 correspondingly push the first limiting portion 21 and the second limiting portion 31 to reset, so that the first lug portion 23 and the second lug portion 33 rotate toward each other to reset. When the first lug portion 23 rotates to drive the first annular portion 22 to rotate, the elastic member 12 pushes the clamping member 11 to reset. At the same time, the clamping member 11 pushes the first limiting portion 21 to reset. When the second lug portion 33 rotates to drive the second annular portion 32 to rotate, the corresponding elastic member 12 pushes the clamping member 11 to reset. At this time, the clamping member 11 pushes the second limiting portion 31 to reset, so that all the clamping members 11 are reset, and they are all held on the outer peripheral side surface of the first rotating shaft 42, thereby realizing the locking of the first rotating shaft 42.

[0057] In some embodiments, the number of clamping members 11 may be one or more, as long as they can achieve tight contact with the first rotating shaft 42. The number of limiting portions and elastic members 12 may match the number of clamping members 11. For example, if the number of clamping members 11, elastic member 12, and rotating member is one, a single slide 41 may be provided, which may extend radially along the first rotating shaft 42. When the lug is rotated, the limiting portion on the annular portion pushes the clamping member 11 to move along the slide 41 away from the first rotating shaft 42, thereby further compressing the elastic member 12, and releasing or disengaging the clamping member 11 from the first rotating shaft 42. For another example, if the number of elastic members 12 and clamping members 11 is two, the two clamping members 11 may be clamped on both sides of the first rotating shaft 42, and the line connecting the two clamping members 11 may pass through the center line of the first rotating shaft 42. Two limiting portions are correspondingly provided on the clamping member 11. For another example, the number of elastic members 12 and clamping members 11 is three, and the three clamping members 11 can clamp the outer circumference of the first rotating shaft 42. The central angle between adjacent clamping members 11 can be 120 degrees. The clamping members 11 are correspondingly provided with three evenly spaced stoppers. Therefore, the number of elastic members 12 and clamping members 11 is not limited, as long as they can tighten the first rotating shaft 42. The extension direction of the sliding groove 41 can be convenient for the stoppers to push.

[0058] In some embodiments, the rotating member may also drive the clamping member 11 to release the rotating shaft through a linkage mechanism.

[0059] In some embodiments, the rotating member may not be provided, and the clamping member 11 is provided with a moving portion located on the outside, and the moving portion is manually moved to drive the clamping member 11 to release the rotating shaft.

[0060] In the second embodiment, based on the first embodiment, another locking assembly is provided between the base 51 and the base bracket 5. The description of the locking assembly can refer to the first embodiment. Alternatively, only one locking assembly may be provided between the base 51 and the base bracket 5. Referring to Figures 3 to 7, the details are as follows:

[0061] The photographic and video head includes at least one locking assembly, a support frame 4, a base bracket 5 rotatably connected to the support frame 4, and a handle assembly 6 for adjusting the pitch angle of the support frame 4. The support frame 4 is used to support photographic and video equipment. The base bracket 5 includes a support body and a base 51 for externally connecting photographic and video equipment. The support body is rotatably connected to the support frame 4, and the lower end of the support body is connected to the base 51. A locking assembly is located between the lower end of the support body and the base 51 to lock or unlock the support body, so that the support body can rotate about a second axis to drive the photographic and video equipment to perform horizontal plane movement.

[0062] Among them, the base 51 is protruding with a second rotating shaft 54 ​​extending along the second axis, and a locking assembly is used to clamp the second rotating shaft 54. The locking assembly includes a rotating part, at least one clamping part 11 and at least one elastic part 12. The elastic part 12 is used to push the clamping part 11 to clamp the outer surface of the second rotating shaft 54. The rotating part rotates to drive the clamping part 11 to release the second rotating shaft 54.

[0063] In this embodiment, referring to Figures 3 and 4, the bracket body includes two upper support portions 52 and a bottom support portion 53 for connecting the bottoms of the two upper support portions 52. A locking assembly is provided between the bottom support portion 53 and the base 51. A second rotating shaft 54 ​​extends horizontally and is used to adjust the horizontal shooting angle of an electronic device such as a camera. After assembly, all elastic members 12 push all clamping members 11 to clamp and lock the second rotating shaft 54. When the rotating member is driven manually or by other driving structures, the clamping member 11 connected to the rotating member is driven to release the second rotating shaft 54, thereby unlocking the second rotating shaft 54. The photographic device or the bracket body is moved to adjust the horizontal shooting angle of the photographic device, such as a camera. Afterwards, after releasing or stopping the actuation of the rotating member, the elastic member 12 pushes the clamping member 11 to return to its original position to relock the second rotating shaft 54, resulting in stable clamping and easy operation.

[0064] In this embodiment, referring to Figure 5, at least one long strip slide groove 41 is recessed on the side of the bracket body away from the base 51, and the outer peripheral surface of the second rotating shaft 54 ​​extends into the slide groove 41. The clamping member 11 and the elastic member 12 are both installed in the slide groove 41. One end of the elastic member 12 is connected to the clamping member 11, and the other end is connected to the side groove wall at one end of the slide groove 41. The rotating member is convexly provided with a limiting portion, which extends into the slide groove 41 and abuts against the side of the clamping member 11 away from the elastic member 12 so that the clamping member 11 clamps the second rotating shaft 54. After assembly, the side of the clamping member 11 located between the elastic member 12 and the limiting portion supports the second rotating shaft 54. When the rotating member rotates to drive the limiting portion to push the clamping member 11 to slide in the slide groove 41, the clamping member 11 releases the second rotating shaft 54.

[0065] In this embodiment, referring to Figures 6 and 7, in order to facilitate more stable clamping, the photo and video platform includes two rotating parts, which are named as the first rotating part 2 and the second rotating part 3 respectively. The first rotating part 2 includes a first annular portion 22, a first through hole is provided in the middle of the first annular portion 22, and at least one first limiting portion 21 is provided on one surface of the first annular portion 22. The second rotating part 3 includes a second annular portion 32, a second through hole is provided in the middle of the second annular portion 32, and at least one second limiting portion 31 is convexly provided on one surface of the second annular portion 32. An arc groove 24 matching the number of the second limiting portions 31 is provided on the first annular portion 22, and one end of the second limiting portion 31 passes through the arc groove 24. A first limiting portion 21 limits a rotating part to extrude an elastic part 12 at one end of a slide groove 41, and a second limiting portion 31 limits a rotating part to extrude an elastic part 12 at the other end of the slide groove 41.

[0066] In this embodiment, to facilitate user adjustment and operation, the locking assembly further includes an unlocking member 13. The unlocking member 13 includes an unlocking portion. The first annular portion 22 and the second annular portion 32 each have recessed sides forming a retaining groove 34. The retaining grooves 34 communicate vertically with each other. The unlocking portion extends through and is held within the retaining grooves 34. Opposing walls of the retaining grooves 34 clamp the unlocking portion. Rotating the unlocking member 13 in the first direction drives the unlocking portion to push the opposing walls of the retaining grooves 34 in opposite directions. The unlocking member 13 is exposed between the two upper support portions 52 and is disposed away from the base 51.

[0067] Among them, after assembly, the first side groove wall of the limiting groove 34 of the first annular portion 22 presses against one side of the unlocking portion, and the second side groove wall of the limiting groove 34 of the second annular portion 32 away from the first side groove wall presses against the other side of the unlocking portion. After rotating the unlocking portion, the unlocking portion simultaneously pushes the first side groove wall and the second side groove wall apart, thereby causing the first annular portion 22 and the second annular portion 32 to rotate in opposite directions.

[0068] To sum up, the photography and video camera head includes two locking components, one locking component is installed between the support frame 4 and the upper support part 52 to adjust the pitch angle of the photography and video equipment, and the other locking component is installed between the base 51 and the bottom support part 53 to adjust the horizontal shooting angle of the photography and video equipment. Therefore, the photography and video camera head runs stably and is easy to operate.

[0069] The above description is merely an optional embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structural transformation made by using the contents of the present application specification and drawings under the application concept of the present application, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present application.
