[0042] The present invention proposes a quick-release rotating structure for use with photographic equipment. Photographic equipment is a general term for cameras, lenses, and related accessories, as well as various devices and items related to photography. Consumables such as film, as well as the photography vests and bags sold by most photographic 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, various filters, 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 release cables, and accessories for the aforementioned equipment. Traditional photographic equipment also includes darkroom printers, enlargers, safelights, glazing machines, constant temperature plates, 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.

[0043] In the first embodiment, as shown in Figures 1, 2 and 4, the quick-release rotary support includes a clamping component 10, an external component 30 and a locking component 20. The clamping component 10 is used to clamp a first photographic device. The clamping component 10 can directly clamp the first photographic device, or it can be connected to a photographic accessory that is compatible with the clamping interface of the clamping component 10 through a camera protection frame, a quick-release plate, a slide bar, etc. The external component 30 is used to connect a second photographic device. The clamping component 10 also includes a rotating shaft 11 for being rotatably connected to the locking component 20. The rotating shaft 11 can be located below the clamping component 10. After assembly, the clamping component 10 can be locked to clamp the first photographic device. The locking component 20 includes a first rotating member 23, a second rotating member 24, a torsion spring 26, at least two clamping members 21 and at least two elastic members 22. The elastic member 22 is used to push the clamping member 21 to clamp on the outer peripheral side surface of the rotating shaft 11 to lock the rotating shaft 11, thereby preventing clamping. The holding assembly 10 rotates relative to the locking assembly 20, the first rotating member 23 is driven and connected to at least one clamping member 21, and the second rotating member 24 is driven and connected to at least one clamping member 21, actuating the first rotating member 23 and the second rotating member 24 to rotate to drive at least two clamping members 21 to release the rotating shaft 11 so that the clamping assembly 10 can rotate around the locking assembly 20. At the same time, the two force arms of the torsion spring 26 and the first rotating member 23 and the second rotating member 24 generate a torsional force, thereby adjusting the shooting angle of the electronic device clamped by the clamping assembly 10, thereby unlocking the rotating shaft 11 through the first rotating member 23 and the second rotating member 24. The operation is simple and fast. After releasing the first rotating member 23 and the second rotating member 24, the torsion spring 26 drives the first rotating member 23 and the second rotating member 24 to reset, so that the elastic member 22 and the torsion spring 26 work together to reset the clamping member 21, and the clamping member 21 clamps the rotating shaft 11 again. The operation is simple, fast and stable.

[0044] In this embodiment, as shown in Figures 3 to 5, the first rotating member 23 and the second rotating member 24 respectively drive two or more clamping members 21 in opposite directions to release the rotating shaft 11. The first rotating member 23 and the second rotating member 24 can be driven manually, or the first rotating member 23 and the second rotating member 24 can be driven to rotate by other structures, such as a pressing structure, a pushing structure, etc.

[0045] Specifically, as shown in FIG6 , to stably clamp the rotating shaft 11 , four clamping members 21 may be provided, and four elastic members 22 are provided correspondingly. Each elastic member 22 is used to push one clamping member 21 , the first rotating member 23 drives two of the clamping members 21 , and the second rotating member 24 drives the other two of the clamping members 21 . The four clamping members 21 surround the outer circumference of the rotating shaft 11 , and the central angle between adjacent clamping members 21 can be 90°. The number of clamping members 21 can be set according to usage needs, such as 6, 8, etc.

[0046] Furthermore, as shown in Figures 4 and 6, the quick-release rotating structure also includes a shaft seat 40 for mounting the locking assembly 20. The shaft seat 40 is rotatably sleeved on the rotating shaft 11. One side of the shaft seat 40 is recessed with at least one long first sliding groove 41 arranged around the rotating shaft 11. Each first sliding groove 41 accommodates a clamping member 21 and an elastic member 22. One end of the clamping member 21 presses the elastic member 22 against one end of the first sliding groove 41, and the other end of the clamping member 21 presses against the rotating shaft 11 through the notch at the other end of the first sliding groove 41.

[0047] The shaft seat 40 is also recessed with at least one long second slide groove 42 arranged around the rotating shaft 11. Each second slide groove 42 accommodates a clamping member 21 and an elastic member 22. One end of the clamping member 21 presses the elastic member 22 against one end of the second slide groove 42, and the other end of the clamping member 21 presses against the rotating shaft 11 through the notch at the other end of the second slide groove 42. The notch of the first slide groove 41 is adjacent to or communicates with the notch of the second slide groove 42. The overall structure is compact and easy to install.

[0048] An elastic member 22 is positioned between a clamping member 21 and one side wall of the first or second chute 41, 42. One end of the elastic member 22 is connected to the clamping member 21, while the other end is connected to one side wall of the first or second chute 41, 42. The openings of the first and second chute 41, 42 can form a large V-shape. The shaft seat 40 is disc-shaped, with a thickness adjusted to suit specific needs.

[0049] Furthermore, as shown in FIG5 , the first rotating member 23 is provided with a first limiting portion 231 convexly. The first limiting portion 231 extends into the first sliding groove 41 and abuts against a side of the clamping member 21 away from the elastic member 22 therein. When the first rotating member 23 is actuated, the first limiting portion 231 pushes the clamping member 21 to release the rotating shaft 11.

[0050] The second rotation member 24 is provided with a second limiting portion 241 . The second limiting portion 241 extends into the second sliding groove 42 and abuts against a side of the clamping member 21 away from the elastic member 22 . When the second rotation member 24 is actuated, the second limiting portion 241 pushes the clamping member 21 to release the rotating shaft 11 .

[0051] Specifically, the first rotating member 23 includes a first annular portion 232 and a first lug portion 233. The first lug portion 233 facilitates driving the first annular portion 232 to rotate. A first through hole 234 is defined in the middle of the first annular portion 232. The first lug portion 233 is protruded from the outer side of the first annular portion 232. A plurality of first limiting portions 231 are spaced apart on the upper surface of the first annular portion 232 and are distributed around the first through hole 234. Each first limiting portion 231 is used to push a clamping member 21 to release the rotating shaft 11.

[0052] The second rotating member 24 includes a second annular portion 242 and a second lug portion 243. A second through hole 245 is provided in the middle of the second annular portion 242. The second through hole 245 is used to rotatably accommodate the rotating shaft 11. The second lug portion 243 is protruded from the outer side of the second annular portion 242. An inner ring portion 244 is protruded from the upper surface of the second annular portion 242 and is arranged around the second through hole 245. A plurality of second limiting portions 241 are evenly spaced on the upper portion of the inner ring portion 244. The first rotating member 23 and the second rotating member 24 are overlapped with each other, and the inner ring portion 244 is rotatably accommodated in the first through hole 234. The torsion spring 26 is located between the first annular portion 232 and the second annular portion 242. When the first lug portion 233 and the second lug 243 are actuated, the first limiting portion 231 and the second limiting portion 241 respectively push the clamping member 21 to move. One force arm of the torsion spring 26 is connected to the first annular portion 232, and the other force arm of the torsion spring 26 is connected to the second annular portion 242.

[0053] After assembly, a first limiting portion 231 abuts against a clamping member 21, and a second limiting portion 241 abuts against another clamping member 21. The first lug portion 233 and the second lug portion 243 can be driven to rotate manually or by other structures, so that the first lug portion 233 and the second lug portion 243 both rotate around the rotating shaft 11 in opposite rotation directions, so that the first limiting portion 231 pushes the clamping member 21 to release the rotating shaft 11, and the second limiting portion 241 pushes the clamping member 21 to release the rotating shaft 11, such as the first lug portion 233 rotates clockwise and the second lug portion 243 rotates counterclockwise, so that all the clamping members 21 release the rotating shaft 11 at the same time, thereby realizing the rotation of the clamping assembly 10.

[0054] In this embodiment, the first limiting portion 231 can be in the shape of a curved plate or an arcuate plate, and the second limiting portion 241 can also be in the shape of a curved plate or an arcuate plate. The connection between the elastic member 22 and the clamping member 21 can be fixed, abutted, or removable, without limitation. The elastic member 22 can be a spring, such as a compression spring or a tension spring. The inner ring portion 244 is annular. The clamping members 21 are evenly spaced about the outer circumference of the rotating shaft 11.

[0055] Furthermore, as shown in Figures 3 to 6, in order to facilitate the control and adjustment of the rotating parts, the quick-release rotating structure also includes an unlocking member 25, which drives the first lug portion 233 and the second lug portion 243 to move. The facing surfaces of the first lug portion 233 and the second lug portion 243 may be inclined surfaces. When the unlocking member 25 is pressed to slide, the two sides of the unlocking member 25 slide along the inclined surfaces of the first lug portion 233 and the second lug portion 243 respectively, thereby pushing the first lug portion 233 and the second lug portion 243 to move in opposite directions. Of course, it can be understood that the first lug portion 233 and the second lug portion 243 extend outward from the quick-release rotating structure respectively, and the first lug portion 233 and the second lug portion 243 are directly moved manually to move in the opposite directions respectively, and the first lug portion 233 and the second lug portion 243 are released. The torsion spring 26 and the elastic member 22 can push the clamping member 21 to reset, and the clamping member 21 pushes the first limiting portion 231 and the second limiting portion 241 to reset, thereby resetting the first lug portion 233 and the second lug portion 243.

[0056] Furthermore, as shown in FIG3 , the side surfaces facing each other of the first lug portion 233 and the second lug portion 243 are first inclined surfaces, and a trapezoidal receiving groove is formed between the two first inclined surfaces. The unlocking member 25 has a trapezoidal driving portion 251 , and the free end of the driving portion 251 is clamped between the two first inclined surfaces.

[0057] The unlocking member 25 has a driving portion 251 at one end and a pressing portion 252 at the other end. The pressing portion 252 extends out of the shaft seat 40 for the user to press. The driving portion 251 is located between the first lug portion 233 and the second lug portion 243. The inclined surfaces of the first lug portion 233 and the second lug portion 243 facing each other form an inverted triangle or trapezoidal space. The outer periphery of the driving portion 251 is correspondingly arranged in an inverted triangle or trapezoidal shape. Pulling the pressing portion 252 causes the driving portion 251 to slide along the inclined surfaces of the first lug portion 233 and the second lug portion 243, so that the angle between the first lug portion 233 and the second lug portion 243 increases, thereby causing the first limiting portion 231 and the second limiting portion 241 to slide simultaneously to push the corresponding clamping member 21 respectively, thereby causing all clamping members 21 to release the rotating shaft 11. After releasing the pressing portion 252, the torsion spring 26 pulls the first rotating member 23 and the second rotating member 24 to return to their original position, and the elastic member 22 pushes the clamping member 21 to return to its original position. The first lug portion 233 may be a flat triangle, and the second lug portion 243 may also be a flat triangle.

[0058] Furthermore, the quick-release rotation structure also includes a rear axle cover 50, which is fixed on the side of the axle seat 40 away from the clamping assembly 10. The first rotating member 23 and the second rotating member 24 are both accommodated in the accommodating cavity formed between the rear axle cover 50 and the axle seat 40. The rear axle cover 50 is provided with an upper opening 51, so that the first lug portion 233 and the second lug portion 243 extend out of the accommodating cavity from the upper opening 51. One of the unlocking member 25 and the rear axle cover 50 is provided with a limiting column 52, and the other is provided with a limiting groove 53. For example, the rear axle cover 50 is provided with a limiting groove 53 extending along the sliding direction of the unlocking member 25, and the surface of the unlocking member 25 is provided with a limiting column 52 to limit the sliding range of the unlocking member 25 and improve stability.

[0059] Furthermore, as shown in FIG5 and FIG7, the quick-release rotating structure further includes an external component 70 located on a side of the rear axle cover 50 away from the axle seat 40, and the external component 70 is used to connect with the second photographic equipment;

[0060] The quick-release rotation structure also includes a sleeve 60, an open side of the sleeve 60 is fixedly connected to the rear axle cover 50, and the axle seat 40 and the locking assembly 20 are located in the sleeve 60, one end of the rotating shaft 11 passes through the sleeve 60 and is fixedly connected to the clamping assembly 10, and the pressing portion 252 of the unlocking member 25 passes through the sleeve 60.

[0061] In summary, after the quick-release rotating structure is assembled, all the clamping members 21 are clamped on the outer periphery of the rotating shaft 11, and the driving portion 251 is located in the trapezoidal space formed by the first inclined surfaces facing each other of the first lug portion 233 and the second lug portion 243. When the rotating shaft 11 needs to be unlocked, the pressing portion 252 is pressed downward to make the limiting column 52 slide along the limiting groove 53. The two sides of the driving portion 251 slide along the first inclined surfaces facing each other of the first lug portion 233 and the second lug portion 243, so that the first lug portion 233 and the second lug portion 243 rotate in opposite directions, and the torsion spring 26 generates a torsion force, and the first lug portion 233 rotates to When the first annular portion 232 is driven to rotate, a first limiting portion 231 pushes a clamping member 21 to slide away from the central axis of the rotating shaft 11 to release the rotating shaft 11. When the second lug portion 243 rotates to drive the second annular portion 242 to rotate, a second limiting portion 241 pushes another clamping member 21 to slide away from the central axis of the rotating shaft 11 to release the rotating shaft 11. All elastic members 22 are compressed, so that all clamping members 21 release the rotating shaft 11. Therefore, the user can rotate the rotating shaft 11 to drive the clamping assembly 10 to rotate to adjust the angle of the first photographic equipment, such as adjusting the shooting angle of electronic products such as cameras.

[0062] When the second lug 243 rotates to drive the second annular portion 242 to rotate, the elastic member 22 pushes the clamping member 21 to return to its original position, and the clamping member 21 pushes the second limiting portion 231 to return to its original position. When the second lug 243 rotates to drive the second annular portion 242 to rotate, the elastic member 22 pushes the clamping member 21 to return to its original position, and the clamping member 21 pushes the second limiting portion 241 to return to its original position, so that all the clamping members 21 are reset, that is, they are all held on the outer peripheral side surface of the rotating shaft 11, thereby achieving the locking of the rotating shaft 11.

[0063] In some implementations, the number of clamping members 21 can be one or more, as long as they can tighten the rotating shaft 11. For example, the number of elastic members 22 and clamping members 21 can be two, and the two clamping members 21 can clamp on both sides of the rotating shaft 11. The line connecting the two clamping members 21 can pass through the centerline of the rotating shaft 11, and the first and second limit portions on the clamping members 21 correspond. In another example, the number of elastic members 22 and clamping members 21 can be three, and the three clamping members 21 can clamp on the outer peripheral surface of the rotating shaft 11. The central angle between adjacent clamping members 21 can be 120°, and the clamping member 21 corresponds to three evenly spaced limit portions. Therefore, the number of elastic members 22 and clamping members 21 is not limited, as long as they can tighten the rotating shaft 11.

[0064] In some embodiments, the clamping assembly 10 may have a variety of structures. The clamping assembly 10 includes a clamping seat with a clamping groove. The groove wall on one side of the clamping groove can be controlled by a screw to move closer to or away from the groove wall on the other side to lock or unlock. One end of the rotating shaft 11 is fixedly connected to the side of the clamping seat away from the clamping groove and can be connected by a locking member such as a screw. The other end of the rotating shaft 11 can be rotatably connected to the rear axle cover 50 by a screw.

[0065] In some embodiments, the clamping assembly 10 includes a threaded disk, two clamping jaws, and a fixed seat. The upper surface of the threaded disk is provided with a spiral line, the spiral line guide forms a notch, the lower end of the clamping jaw is provided with a plurality of fixed teeth, the plurality of fixed teeth are spaced to form a thread, the fixed teeth of the clamping jaw are nested between the notches formed by the spiral line guide, and a clamping space is formed between the two clamping jaws for clamping a first photographic equipment such as a quick release plate; and the fixed seat is rotatably connected to the threaded disk, the fixed seat is radially provided with two limiting grooves, one clamping jaw is limited to one limiting groove, the bottom surface of the fixed seat is provided with a rotating shaft 11, the rotating shaft 11 passes through the central circular hole of the threaded disk, the lower surface of the threaded disk has a recessed accommodating space, and the threaded disk covers the outer periphery above the shaft seat 40, resulting in a compact structure and a tight connection. The locking control of the clamping assembly 10 and the locking assembly 20 can be performed separately without affecting each other.

[0066] Among them, the rotation of the threaded disk will cause the threaded groove on the threaded disk and the threaded fixed teeth on the clamping jaw to move relative to each other, and the fixed teeth on the clamping jaw will slide in the threaded groove on the threaded disk. Its moving pair is similar to the threaded pair form of threaded connection, and the spiral teeth formed by the thread line and the fixed teeth on the clamping jaw constitute a structure similar to the threaded pair.

[0067] When the threaded disk is rotated forward, the threads on the disk move relative to the fixed teeth on the clamping jaws. Constrained by the limit slots on the fixed seat, the clamping jaws move closer to each other along the radial direction of the disk, thereby clamping photographic accessories of different sizes, such as quick-release plates. After clamping, no further locking structure such as the locking assembly 20 is required. The structure is compact and simple, and operation is convenient. When the threaded disk quick release device needs to be unlocked, the disk is rotated backward, and the threads on the disk move relative to the fixed teeth on the clamping jaws. Constrained by the limit slots on the fixed seat, the clamping jaws move away from each other along the radial direction of the disk, thereby releasing and unlocking the photographic accessory. The simultaneous radial movement of the two clamping jaws enables the clamping and fixing of photographic accessories of different sizes, such as quick-release plates and sliders. Forward rotation and reverse rotation are opposite rotation directions. For example, forward rotation can be clockwise, which conforms to human operating habits and improves user experience, while reverse rotation can be counterclockwise. The clamping claw can be located on one side of the fixing base, and the other side of the fixing base can be connected to other photographic accessories or equipment, thereby realizing the disassembly and assembly function of the threaded disk quick-release device, which has the advantages of being easy to use, convenient to carry, easy to disassemble and assemble, and having a wide range of applications.

[0068] In some embodiments, the external assembly 30 includes an external seat, which is located below the shaft seat 40, and has inclined edges on two opposite sides of the external seat; or the external seat has inclined edges on two opposite sides, and the external seat also has inclined edges on two other opposite sides, and the inclined edges are connected by arc surfaces, so that the external seat has no installation direction and has strong applicability. The bottom surface of the external seat has a cross groove for engaging other quick-install structures.

[0069] Among them, the camera and other electronic devices can be locked to the upper surface of the quick-release plate by screws, and then the quick-release plate is slid into the clamping space of the dovetail groove. When the threaded disk is rotated forward, the threaded lines on the threaded disk and the fixed teeth on the clamping claws move relative to each other. Under the restriction of the limit groove on the fixed seat, the clamping claws approach each other in the radial direction of the threaded disk to shrink the clamping space until the inclined edges of the two clamping claws are clamped on both sides of the quick-release plate and other photographic accessories. The external seat of the external component 30 can be clamped and connected with other quick-release structures to achieve the connection of the electronic device; when the clamping component 10 needs to be unlocked, the threaded disk is rotated backward, and the threaded lines on the threaded disk and the fixed teeth on the clamping claws move relative to each other. Under the restriction of the limit groove on the fixed seat, the clamping claws move away from each other in the radial direction of the threaded disk to release the two sides of the quick-release plate and other photographic accessories. The two sides of the quick-release plate and other photographic accessories can slide out from the inclined edges of the two clamping claws to achieve the release and unlocking of the photographic accessories.

[0070] In some embodiments, the external component 70 may also be a clamping structure, a threaded structure, a snap-on structure, etc., which are not specifically listed here. The second photographic equipment may be a side handle, a top handle, etc. As shown in FIG2 , if the threaded structure includes a mounting base, the mounting base may be provided with a threaded hole.

[0071] The above descriptions are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present description and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
