Digital cameras have integrated photography and video recording, so they are also called more extensive imaging equipment, including the two major camps of photography and video recording.

[0036] The present utility model provides a quick-release assembly, as Figures 1 to 7 shown. The quick-release assembly includes a rotating shaft 11 and a locking assembly 20 for clamping the rotating shaft 11. The locking assembly 20 includes a rotating member, at least one clamping member 21 and at least one elastic member 22. The elastic member 22 is used to push the clamping member 21 to clamp on the outer peripheral surface of the rotating shaft 11, and the rotating member rotates to drive the clamping member 21 to release the rotating shaft 11.

[0037] In this embodiment, the quick-release assembly applies a clamping force to the clamping member 21 to clamp the rotating shaft 11 through the elastic member 22 to lock the rotating shaft 11. By actuating the rotating member, the clamping member 21 is driven to release the rotating shaft 11. After releasing the rotating member, the elastic member 22 drives the clamping member 21 to reset to clamp the rotating shaft 11 again, thereby realizing the locking or unlocking of the rotating shaft 11. Furthermore, the first external connection assembly connected to the rotating shaft 11 can adjust the angle. If the first external connection assembly can install a photographic device, the shooting angle of the photographic device can be adjusted. The operation is simple and fast. The present utility model also proposes a photographic kit.

[0038] Among them, the number of the clamping members 21 can be one. One clamping member 21 cooperates with the side wall of the installation position of the rotating shaft 11 to realize the clamping or unlocking of the rotating shaft 11. The number of the clamping members 21 can be two or more, such as three clamping members 21, with stable clamping, and no further limitation will be made one by one here. The rotating shaft 11 can be cylindrical, and the clamping member 21 can also be cylindrical extending along the axial direction of the rotating shaft 11, which is convenient for clamping and operation. The elastic member 22 can be a spring. There are many ways to actuate the rotating member, which can be directly driven by a braking member, or can be driven by an actuating assembly or an actuating structure, and no further limitation will be made one by one here.

[0039] In some embodiments, the quick-release assembly further includes a connection seat 40 for installing the locking assembly 20. At least one long strip-shaped chute 41 is concavely provided on the lower end surface of the connection seat 40. The connection seat 40 can be in a disc shape. An installation space for installing the locking assembly 20 is concavely provided on the bottom surface of the disc. The clamping member 21 and the elastic member 22 are both installed in the chute 41. One end of the elastic member 22 is connected to the clamping member 21, and the other end is connected to the side wall of one end of the chute 41. The rotating member is convexly provided with a limiting portion, and the limiting portion extends into the chute 41 and abuts against the side of the clamping member 21 away from the elastic member 22 so that the clamping member 21 clamps the rotating shaft 11. After assembly, the side surface of the clamping member 21 between the elastic member 22 and the limiting portion abuts against the rotating shaft 11. When the rotating member rotates to drive the limiting portion to push the clamping member 21 to slide in the chute 41, the clamping member 21 releases the rotating shaft 11, so that the rotating shaft 11 can rotate. After releasing the rotating member, the elastic member 22 pushes the clamping member 21, so that when the clamping member 21 pushes the limiting portion to rotate, the rotating member resets.

[0040] In some embodiments, please refer to Figure 5 , the rotating member includes an annular portion and a convex ear portion. The convex ear portion protrudes outside the annular portion. A through hole for rotatably accommodating the rotating shaft 11 is provided in the middle of the annular portion. At least one limiting portion is convexly provided on the upper surface of the annular portion. When the convex ear portion is actuated, the annular portion drives the limiting portion to push the clamping member 21 to release the rotating shaft 11.

[0041] In some embodiments, the upper surface of the annular portion is convexly provided with three limiting portions distributed around the through hole. One limiting portion is matched with a clamping member 21 and an elastic member 22. The lower end surface of the connecting seat 40 is concavely provided with three sliding grooves 41, so as to realize more stable clamping of the rotating shaft 11.

[0042] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 4 , the quick-release assembly includes two rotating members, which are respectively named the first rotating member 23 and the second rotating member 24. The first rotating member 23 includes a first annular portion 232 and a first convex ear portion 233. A first through hole 234 is provided in the middle of the first annular portion 232. The upper surface of the first annular portion 232 is provided with at least one first limiting portion 231 distributed around the first through hole 234. The second rotating member 24 includes a second annular portion 242 and a second convex ear portion 243. A second through hole 245 is provided in the middle of the second annular portion 242. The upper surface of the second annular portion 242 is convexly provided with an inner ring portion 244 arranged around the second through hole 245. At least one second limiting portion 241 is provided at the upper end of the inner ring portion 244. The first annular portion 232 is located above the second annular portion 242, and the inner ring portion 244 is rotationally received in the first through hole 234. One first limiting portion 231 limits a rotating member to squeeze the elastic member 22 at one end of a sliding groove 41, and one second limiting portion 241 limits a rotating member to squeeze an elastic member 22 at the other end of the sliding groove 41.

[0043] In some embodiments, the number of the sliding grooves 41 is three and they are distributed in a triangle. A first limiting portion 231 and a second limiting portion 241 are slidably received in one sliding groove 41, and the second limiting portion 241 rotates within the inner circle of the first limiting portion 231. The first limiting portion 231 and the second limiting portion 241 can be disc-shaped.

[0044] In some embodiments, the quick-release assembly further includes an unlocking member 25. The unlocking member 25 includes an unlocking portion 251. The unlocking portion 251 is clamped between the first convex ear portion 233 and the second convex ear portion 243. When the unlocking member 25 slides in the first direction, it drives the unlocking portion 251 to drive the first convex ear portion 233 and the second convex ear portion 243 to rotate in opposite directions, so as to realize that the unlocking member 25 simultaneously drives the first convex ear portion 233 and the second convex ear portion 243 to rotate around the rotating shaft 11. After releasing the unlocking member 25, the elastic member 22 pushes the rotating member to push the first limiting portion 231 and the second limiting portion 241 to reset, and at the same time, the first convex ear portion 233 and the second convex ear portion 243 drive the unlocking member 25 to reset.

[0045] In some embodiments, for convenient operation, the cross-section of the unlocking portion 251 is triangular. A triangular clamping hole matching the unlocking portion 251 is formed between the first convex ear portion 233 and the second convex ear portion 243. One corner portion of the unlocking portion 251 faces away from the rotating shaft 11. During the resetting process of the first limiting portion 231 and the second limiting portion 241, the inclined surfaces on both sides of the clamping hole slide relative to the surface of the unlocking portion 251 to drive the unlocking portion 251 to reset.

[0046] In some embodiments, the unlocking member 25 further includes a sliding portion. The unlocking portion 251 protrudes from the sliding portion. One end of the sliding portion extending outside the connecting seat 40 has a handheld portion 252. The sliding portion is slidably connected to the connecting seat 40. Therefore, the user holds or pinches the handheld portion 252 and pulls the sliding portion outward to unlock the rotating shaft 11, and can release the handheld portion 252 to reset, or can also push the handheld portion 252 to reset the unlocking member 25.

[0047] In some embodiments, the quick-release assembly further includes a bottom cover. The bottom cover limits the locking assembly 20 within the connecting seat 40, making the whole compact and combined together.

[0048] The present utility model also proposes a photography kit. The photography kit includes the quick-release assembly as described above. The quick-release assembly includes a rotating shaft 11, a locking assembly 20 for clamping the rotating shaft 11. The locking assembly 20 includes a rotating member, at least one clamping member 21 and at least one elastic member 22. The elastic member 22 is used to push the clamping member 21 to clamp on the outer peripheral surface of the rotating shaft 11, and the rotating member rotates to drive the clamping member 21 to release the rotating shaft 11.

[0049] In some embodiments, the photography kit further includes a first external connection assembly and a second external connection assembly. The first external connection assembly is connected to the rotating shaft 11, and the first external connection assembly is fixedly connected to the quick-release assembly. The first external connection assembly is used to install a photographic and video device. The first external connection assembly can be a clamping assembly 10, an adapter bracket, a magic arm, a camera protection frame and other installation assemblies capable of installing a photographic and video device. The second external connection assembly can be a connection device for connecting to a support device, such as a quick-release plate, a cold shoe slot, a threaded hole, etc.

[0050] In the first embodiment, the first external connection assembly is a clamping assembly 10, and the second external connection assembly is an external connection assembly 30, which together form a quick-release rotating bracket, specifically as follows:

[0051] In this embodiment, as Figure 1 and Figure 2As shown in the figure, the quick-release rotating bracket includes a clamping assembly 10, an external connection assembly 30, and a locking assembly 20. The clamping assembly 10 is used to clamp the first photographic equipment. The clamping assembly 10 can directly clamp the first photographic equipment, or can be connected to the clamping interface of the clamping assembly 10 through photographic accessories such as a camera protection frame, a quick-release plate, and a slide bar that are adapted to it. The external connection assembly 30 is used to connect the second photographic equipment. The clamping assembly 10 further includes a rotating shaft 11 for rotatably connecting with the locking assembly 20. The rotating shaft 11 can be located below the clamping assembly 10. After assembly, the clamping assembly 10 can be locked to clamp the first photographic equipment. The locking assembly 20 includes a rotating member, a clamping member 21, and an elastic member 22. The elastic member 22 is used to push the clamping member 21 to clamp on the outer peripheral surface of the rotating shaft 11 to lock the rotating shaft 11, thereby preventing the clamping assembly 10 from rotating relative to the locking assembly 20. The rotating member rotates to drive the clamping member 21 to release the rotating shaft 11 so that the clamping assembly 10 can rotate around the locking assembly 20, thereby adjusting the shooting angle of the electronic device clamped by the clamping assembly 10. Thus, unlocking the rotating shaft 11 can be achieved with one-key and one-step operation by the rotating member, and the operation is simple and fast.

[0052] In this embodiment, as Figures 3 to 5 shown, the number of rotating members can be 2, which are respectively named the first rotating member 23 and the second rotating member 24. The first rotating member 23 and the second rotating member 24 drive more than two clamping members 21 to release the rotating shaft 11 in opposite directions.

[0053] Specifically, in order to stably clamp the rotating shaft 11, the number of clamping members 21 can be 6, and the number of elastic members 22 is correspondingly provided with 6. One elastic member 22 is used to push one clamping member 21. The quick-release rotating bracket further includes a connecting seat 40 for installing the locking assembly 20. The lower surface of the connecting seat 40 can be recessed with 3 long strip-shaped sliding grooves 41. The 3 long strip-shaped sliding grooves 41 are sequentially close to each other end to end to be distributed in a triangular shape. The sliding grooves 41 are used to slidably accommodate the clamping members 21 and the elastic members 22. Each sliding groove 41 is provided with 2 elastic members 22 and 2 clamping members 21. The 2 elastic members 22 are respectively located at both ends of the corresponding sliding groove 41. One elastic member 22 is located between one clamping member 21 and the side groove wall at one end of the corresponding sliding groove 41, that is, one end of the elastic member 22 is connected to the clamping member 21, and the other end is connected to the side groove wall at one end of the corresponding sliding groove 41. The clamping member 21 can slide along the extending direction of the sliding groove 41;

[0054] The first rotating member 23 includes a first annular portion 232 and a first convex ear portion 233. The first convex ear portion 233 is convenient for driving the first annular portion 232 to rotate. A first through hole 234 is provided in the middle of the first annular portion 232. The first convex ear portion 233 protrudes from the outer side surface of the first annular portion 232. Three first limiting portions 231 distributed around the first through hole 234 are spaced on the upper surface of the first annular portion 232. Each first limiting portion 231 is used to push one clamping member 21 to release the rotating shaft 11;

[0055] The second rotating member 24 includes a second annular portion 242 and second lug portions 243. A second through hole 245 is provided in the middle of the second annular portion 242. The second through hole 245 is used for rotatably accommodating the rotating shaft 11. The second lug portions 243 protrude from the outer side surface of the second annular portion 242. An inner ring portion 244 surrounding the second through hole 245 is protruded on the upper surface of the second annular portion 242. Three second limiting portions 241 are uniformly spaced on the upper part of the inner ring portion 244. The first rotating member 23 is located above the second rotating member 24, and the inner ring portion 244 is rotatably accommodated in the first through hole 234. One end of each sliding groove 41 has a first limiting portion 231, and the other end has a second limiting portion 241.

[0056] After assembly, one first limiting portion 231 abuts against one clamping member 21, and one second limiting portion 241 abuts against the other clamping member 21. By rotating the first lug portion 233 and the second lug portion 243, the first lug portion 233 and the second lug portion 243 can both rotate around the rotating shaft 11 along opposite rotation directions, so that the first limiting portion 231 and the second limiting portion 241 both slide towards the two ends of the sliding groove 41. For example, the first lug portion 233 rotates clockwise and the second lug portion 243 rotates counterclockwise, so that the 6 clamping members 21 release the rotating shaft 11 at the same time, and then the rotation of the clamping assembly 10 is realized.

[0057] In this embodiment, the limiting portion can be in the shape of a curved sheet. The connection manner between the elastic member 22 and the clamping member 21 can be fixed connection, abutting connection, detachable connection, and is not specifically limited. The elastic member 22 can be a spring, such as a compression spring, a tension spring, etc. The first lug portion 233 can be flat.

[0058] Furthermore, as Figure 6 shown, in order to facilitate the control and adjustment of the rotating member, the quick-release rotating bracket further includes an unlocking member 25. The first lug portion 233 and the second lug portion 243 are driven to move by the unlocking member 25. The opposite surfaces of the first lug portion 233 and the second lug portion 243 can be inclined surfaces. When the unlocking member 25 slides, 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, so as to push 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 respectively protrude out of the outer side of the quick-release rotating bracket, and the first lug portion 233 and the second lug portion 243 are directly manually moved in opposite directions to release the first lug portion 233 and the second lug portion 243. The elastic member 22 can push the clamping member 21 to reset, so that the clamping member 21 pushes the first limiting portion 231 and the second limiting portion 241 to reset, so as to reset the first lug portion 233 and the second lug portion 243.

[0059] Furthermore, as Figure 1As shown, the unlocking member 25 includes an unlocking portion 251 and a sliding portion. The unlocking portion 251 protrudes from the sliding portion. One end of the sliding portion extending outside the connecting seat 40 has a handheld portion 252. The unlocking portion 251 is located between the first convex ear portion 233 and the second convex ear portion 243. The inclined surfaces of the first convex ear portion 233 and the second convex ear portion 243 facing each other form an inverted triangular space, and the outer periphery of the unlocking portion 251 is correspondingly arranged in an inverted triangle. When pulling the handheld portion 252 in a direction away from the threaded disc 13, the unlocking portion 251 slides along the inclined surfaces of the first convex ear portion 233 and the second convex ear portion 243, so that the included angle between the first convex ear portion 233 and the second convex ear portion 243 increases, thereby enabling the first limiting portion 231 and the second limiting portion 241 to slide simultaneously to respectively push the clamping members 21 at both ends of the chute 41, so that all the clamping members 21 release the rotating shaft 11.

[0060] In summary, after the quick-release rotating bracket is assembled, all the clamping members 21 are clamped on the outer peripheral surface of the rotating shaft. The unlocking portion 251 is located in the inverted triangular space formed by the inclined surfaces of the first convex ear portion 233 and the second convex ear portion 243 facing each other. During the process of unlocking the rotating shaft 11, when pulling the handheld portion 252 outward to drive the sliding portion to slide, the unlocking portion 251 slides along the inclined surfaces of the first convex ear portion 233 and the second convex ear portion 243 facing each other, so that the first convex ear portion 233 and the second convex ear portion 243 rotate in opposite directions. When the first convex ear portion 233 rotates to drive the first annular portion 232 to rotate, a first limiting portion 231 pushes a clamping member 21 to slide. When the second convex ear portion 243 rotates to drive the second annular portion 242 to rotate, a second limiting portion 241 pushes another clamping member 21 to slide, and the elastic member 22 is compressed, so that all the clamping members 21 release the rotating shaft 11, so that the user can rotate the fixed seat 12 to adjust the shooting angle of electronic products such as cameras; after adjustment, when the handheld portion 252 is pushed in the reverse direction to drive the sliding portion to slide, the unlocking portion 251 slides along the inclined surfaces of the first convex ear portion 233 and the second convex ear portion 243 facing each other, and the elastic member 22 pushes the first limiting portion 231 and the second limiting portion 241 to reset, so that the first convex ear portion 233 and the second convex ear portion 243 rotate towards each other to reset. When the first convex ear portion 233 rotates to drive the first annular portion 232 to rotate, the elastic member 22 pushes the clamping member 21 to reset, and the clamping member 21 pushes the first limiting portion 231 to reset. When the second convex ear portion 243 rotates to drive the second annular portion 242 to rotate, the elastic member 22 pushes the clamping member 21 to reset, and the clamping member 21 pushes the second limiting portion 241 to reset, so that all the clamping members 21 are reset, that is, they all abut against the outer peripheral surface of the rotating shaft 11, thereby realizing the locking of the rotating shaft 11.

[0061] In some embodiments, the number of the clamping members 21 can be one or more, as long as the rotation shaft 11 can be tightly pressed. The number of the limiting portions and the elastic members 22 can match the number of the clamping members 21. For example, the number of the clamping members 21, the elastic members 22, and the rotating members is all one, and the sliding groove 41 of the connecting seat 40 can be provided with one, which can extend radially along the rotation shaft 11. When the rotating lug is rotated, the limiting portion on the annular portion pushes the clamping member 21 to move along the sliding groove 41 away from the rotation shaft 11, so that the clamping member 21 further compresses the elastic member 22, realizing that the clamping member 21 loosens or disengages from the rotation shaft 11. Another example is that the number of the elastic members 22 and the clamping members 21 is both two. The two clamping members 21 can clamp on both sides of the rotation shaft 11, and the connection line of the two clamping members 21 can pass through the center line of the rotation shaft 11. Two limiting portions are correspondingly provided on the clamping member 21. Another example is that the number of the elastic members 22 and the clamping members 21 is both three. The three clamping members 21 can clamp on the outer circumferential side of the rotation shaft 11, and the central angle between adjacent clamping members 21 can be 120°. Three limiting portions evenly distributed at intervals are correspondingly provided on the clamping member 21. Therefore, the number of the elastic members 22 and the clamping members 21 is not limited, as long as the rotation shaft 11 can be clamped tightly. The extending direction of the sliding groove 41 only needs to be convenient for the limiting portion to push.

[0062] In this embodiment, as Figure 1 and Figure 7 shown, the clamping assembly 10 includes a threaded disk 13, two clamping jaws 14 and a fixed seat 12. A spiral line is provided on the upper surface of the threaded disk 13, and the spiral line guides to form a notch. A plurality of fixing teeth are provided at the lower end of the clamping jaw 14, and the plurality of fixing teeth are arranged at intervals to form a thread. The fixing teeth of the clamping jaw 14 are nested between the notches formed by the spiral line guiding. A clamping space is formed between the two clamping jaws 14 for clamping a first photographic equipment such as a quick-release plate; and the fixed seat 12 is rotatably connected with the threaded disk 13. Two limiting grooves 121 are radially formed in the fixed seat 12, and one clamping jaw 14 is limited in one limiting groove 121. A rotation shaft 11 is provided at the bottom surface of the fixed seat 12, and the rotation shaft 11 passes through the circular hole in the middle of the threaded disk 13. The lower surface of the threaded disk 13 has a sunken accommodation space, and the threaded disk 13 covers the outer circumference above the connecting seat 40, with a compact structure and a tight connection. The locking control of the clamping assembly 10 and the locking assembly 20 can be carried out separately without affecting each other.

[0063] Among them, the rotation of the threaded disk 13 will cause relative movement of the threaded notch on the threaded disk 13 and the thread of the fixing teeth on the clamping jaw 14. The fixing teeth on the clamping jaw 14 will slide in the threaded notch on the threaded disk 13, and its kinematic pair is similar to the form of the thread pair of the threaded connection. The spiral teeth formed by the thread line and the fixing teeth on the clamping jaw 14 constitute a structure similar to the thread pair.

[0064] When the threaded disk 13 is rotated forward, the thread lines on the threaded disk 13 and the fixed teeth on the clamping jaws 14 move relative to each other. Under the restriction of the limiting groove 121 on the fixed seat 12, the clamping jaws 14 approach each other along the radial direction of the threaded disk 13, realizing the clamping of photographic accessories such as quick-release plates of different sizes. After clamping, there is no need to further lock with a locking component 20 or other locking structures. The structure is compact and simple, and the operation is convenient. When it is necessary to unlock the quick-release device of the threaded disk 13, rotate the threaded disk 13 in the reverse direction. The thread lines on the threaded disk 13 and the fixed teeth on the clamping jaws 14 move relative to each other. Under the restriction of the limiting groove 121 on the fixed seat 12, the clamping jaws 14 move away from each other along the radial direction of the threaded disk 13, realizing the release and unlocking of the photographic accessories. The method of making the two clamping jaws 14 move radially at the same time realizes the clamping and fixing of photographic accessories of different sizes, such as quick-release plates and slide bars. Forward rotation and reverse rotation are opposite rotation directions. For example, forward rotation can be clockwise rotation, which conforms to the operating habits of people and improves the use experience. Reverse rotation can be counterclockwise rotation. The clamping jaws 14 can be located on one side of the fixed seat 12, and the other side of the fixed seat 12 can be connected to other photographic accessories or equipment, so as to realize the disassembly and assembly function of the quick-release device of the threaded disk 13, which has the advantages of convenient use, easy carrying, convenient disassembly and wide application range.

[0065] In this embodiment, the external connection component 30 includes an external connection seat 31. The external connection seat 31 is located below the connection seat 40. The opposite sides of the external connection seat 31 have inclined edges 311; or the opposite sides of the external connection seat 31 have inclined edges 311, and the other opposite sides of the external connection seat 31 also have inclined edges 311. The inclined edges 311 are connected by an arc surface, so that the external connection seat 31 has no installation direction and has strong applicability. The bottom surface of the external connection seat 31 has a cross groove for engaging other quick-release structures.

[0066] Among them, electronic devices such as cameras can be locked on 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 13 is rotated forward, the thread lines on the threaded disk 13 and the fixed teeth on the clamping jaws 14 move relative to each other. Under the restriction of the limiting groove 121 on the fixed seat 12, the clamping jaws 14 approach each other along the radial direction of the threaded disk 13 to contract the clamping space until the inclined edges of the two clamping jaws 14 clamp on both sides of photographic accessories such as quick-release plates. The external connection seat 31 of the external connection component 30 can be clamped and connected with other quick-release structures, so as to realize the connection of the electronic device; when it is necessary to unlock the clamping component 10, rotate the threaded disk 13 in the reverse direction. The thread lines on the threaded disk 13 and the fixed teeth on the clamping jaws 14 move relative to each other. Under the restriction of the limiting groove 121 on the fixed seat 12, the clamping jaws 14 move away from each other along the radial direction of the threaded disk 13 to release both sides of photographic accessories such as quick-release plates. Both sides of photographic accessories such as quick-release plates can slide out from the inclined edges of the two clamping jaws 14, realizing the release and unlocking of the photographic accessories.

[0067] In some embodiments, the external component can also be a clamping structure, a threaded structure, a snap structure, etc., and no further setting will be made here one by one.

[0068] In some embodiments, the rotating member can also drive the clamping member to release the rotating shaft through a linkage mechanism.

[0069] In some embodiments, the rotating member may not be provided, and the clamping member is provided with an outer handling portion, and manually handling the handling portion drives the clamping member to release the rotating shaft.
