Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0034] Please also refer to Figures 1 to 7 , the quick-release structure provided in the embodiment of the present application is now described.

[0035] Please also refer to Figures 1 to 4The quick-release structure includes: a mounting base 10, an adapter block 20, a locking assembly 30 and a retaining assembly 40. The mounting base 10 is provided with a mounting groove 111; the adapter block 20 is installed in the mounting groove 111; the locking assembly 30 includes a rotating member 31 and a locking block 32, the rotating member 31 is rotatably connected to the mounting base 10 and connected to the locking block 32, the rotating member 31 is used to drive the locking block 32 to switch between a locked position and an unlocked position, and when the locking block 32 is in the locked position, the locking block 32 locks the adapter block 20 in the mounting groove 111; the retaining assembly 40 includes a convex button 41 and a first elastic member 42, the convex button 41 is movably connected to the mounting base 10, the first elastic member abuts against the convex button 41, and when the locking block 32 is in the unlocked position, the convex button 41 abuts against the rotating member 31 under the action of the first elastic member 42.

[0036] Among them, one of the mounting base 10 and the adapter block 20 is used to connect to the photographic device, and the other is used to connect to the bracket. For example, the mounting base 10 is used to connect to the photographic device, and the adapter block 20 is used to connect to the bracket; or the mounting base 10 is used to connect to the bracket, and the adapter block 20 is used to connect to the photographic device, and the adapter block 20 is used to connect to the photographic device through the detachable connection between the adapter block 20 and the mounting base 10, thereby achieving a detachable connection between the photographic device and the bracket. Of course, in other embodiments, the quick-release structure can also be used for other two components that require a detachable connection, such as the detachable connection between the lamp body and the bracket.

[0037] By rotatably connecting the rotating member 31 to the mounting base 10 and connecting the rotating member 31 to the locking block 32, when the rotating member 31 rotates relative to the mounting base 10, the locking block 32 can be driven to switch between a locked position and an unlocked position. When the locking block 32 is in the locked position, the locking block 32 can lock the adapter block 20 in the mounting groove 111, and the adapter block 20 cannot be removed from the mounting groove 111. When the locking block 32 is in the unlocked position, the locking block 32 unlocks the adapter block 20, and the adapter block 20 can be removed from the mounting groove 111. It can be understood that by locking and unlocking the adapter block 20 by the locking block 32, the adapter block 20 and the mounting base 10 are detachably connected.

[0038] See also Figure 1 and Figure 4 When the rotating member 31 drives the locking block 32 to switch from the locked position to the unlocked position, the rotating member 31 abuts against the convex button 41, compressing the first elastic member 42. At this time, the first elastic member 42 provides a reaction force to the convex button 41, causing the convex button 41 to abut against the rotating member 31, preventing the rotating member 31 from rotating in the opposite direction, thereby keeping the locking block 32 in the unlocked position.

[0039] The quick-release structure provided by the present application is compared with the prior art. In the quick-release structure of the present application, one of the mounting seat 10 and the adapter block 20 is used to connect with the photographic device, and the other is used to connect with the bracket. When the rotating member 31 rotates relative to the mounting seat 10, it can drive the locking block 32 to switch between the locked position and the unlocked position, thereby realizing locking and unlocking of the adapter block 20, making the adapter block 20 detachably connected to the mounting seat 10, and further making the photographic device detachably connected to the bracket. When the rotating member 31 drives the locking block 32 to switch from the locked position to the unlocked position, the convex button 41 abuts against the rotating member 31 under the action of the first elastic member 42, preventing the rotating member 31 from rotating in the opposite direction, thereby keeping the locking block 32 in the unlocked position, without continuously applying external force to the rotating member 31. Specifically, it is necessary to remove the photographic device from the bracket. When disassembling, the user applies an external force to the rotating member 31 with one hand to rotate the rotating member 31 to drive the locking block 32 to switch from the locked position to the unlocked position. When the locking block 32 is in the unlocked position, the convex button 41 elastically abuts against the rotating member 31, so that the rotating member 31 remains stationary, thereby maintaining the locking block 32 in the unlocked position. At this time, the external force on the rotating member 31 is removed, that is, the user's hand leaves the rotating member 31, and the locking block 32 can also be maintained in the unlocked position, so that the user can free up his hands to perform the next operation, such as removing the adapter block 20 from the mounting slot 111, and the photographic equipment can be removed from the bracket with one hand, realizing one-handed operation. The quick-release structure is simple and convenient to operate, and can meet the quick-release requirements, such as being able to quickly and easily remove the photographic device from the bracket.

[0040] In one embodiment of this application, see Figure 2 and Figure 3 The adapter block 20 slides in cooperation with the mounting groove 111. The mounting seat 10 is further provided with an accommodating cavity 13 connected to the mounting groove 111. The locking block 32 is arranged in the accommodating cavity 13. When the locking block 32 is in the locked position, part of the locking block 32 protrudes into the mounting groove 111 and abuts against the adapter block 20.

[0041] Optionally, see Figure 1 、 Figure 3 and Figure 4 The mounting base 10 includes a base body 11 and a back plate 12 . The back plate 12 is connected to the base body 11 and cooperates to form an accommodating cavity 13 . The mounting groove 111 is provided on a side of the base body 11 away from the back plate 12 .

[0042] The sidewall of the base body 11 is provided with a sliding opening 112, which is in communication with the mounting groove 111. The adapter block 20 can slide into or out of the mounting groove 111 through the sliding opening 112. The edge of the mounting groove 111 is provided with a first limiting surface 113, which is inclined toward the mounting groove 111. The adapter block 20 is provided with a second limiting surface 21, which is inclined outward. When the adapter block 20 slides into the mounting groove 111, the first limiting surface 113 and the second limiting surface 21 cooperate and slide in contact, achieving sliding engagement between the adapter block 20 and the mounting groove 111 and preventing the adapter block 20 from disengaging from the mounting groove 111 in a direction perpendicular to the sliding direction.

[0043] The seat body 11 is provided with a through opening 114, which is in communication with the mounting groove 111 and the accommodating chamber 13, that is, the accommodating chamber 13 is in communication with the mounting groove 111 through the through opening 114. When the locking block 32 is in the locked position, part of the locking block 32 protrudes into the mounting groove 111 through the through opening 114 and abuts against the adapter block 20. At this time, the adapter block 20 is in a locked state and cannot slide out of the sliding opening 112. Figure 4 When the locking block 32 is in the unlocked position, the locking block 32 exits the mounting groove 111 and moves away from the adapter block 20. The adapter block 20 is in the unlocked state, and the adapter block 20 can slide out from the sliding opening 112, such as Figure 5 .

[0044] The above technical solution can easily and quickly slide the adapter block 20 into or out of the mounting groove 111 by slidingly engaging the adapter block 20 with the mounting groove 111, making the operation convenient. By arranging the locking block 32 in the accommodating cavity 13, the layout between the locking block 32 and the mounting seat 10 is compact, which is conducive to reducing the overall volume of the quick-release structure and reducing the space occupied by the quick-release structure. Moreover, by connecting the accommodating cavity 13 with the mounting groove 111, when the locking block 32 is in the locked position, a portion of the locking block 32 protrudes into the mounting groove 111 and abuts against the adapter block 20, preventing the adapter block 20 from sliding out of the mounting groove 111, thereby locking the adapter block 20 in the mounting groove 111. When the locking block 32 is in the unlocked position, the locking block 32 withdraws from the mounting groove 111 and moves away from the adapter block 20, allowing the adapter block 20 to slide out of the mounting groove 111. The structure is simple and easy to use.

[0045] In one embodiment of this application, see Figure 2 and Figure 3 The adapter block 20 is a polygon, and the number of sides of the adapter block 20 is greater than or equal to six, and the outer contour of the mounting groove 111 is adapted to the adapter block 20.

[0046] Optionally, the adapter block 20 is a regular polygon, wherein the number of sides of the adapter block 20 can be six, eight, ten, etc. Since the outer contour of the mounting groove 111 is adapted to the adapter block 20, the mounting groove 111 is also a regular polygon, and the number of edge sides of the mounting groove 111 is also greater than or equal to six, for example, six, eight, ten, etc.

[0047] By setting the adapter block 20 to a polygonal structure, the outer contour of the mounting groove 111 is adapted to the adapter block 20, so that when the adapter block 20 slides into the mounting groove 111, the adapter block 20 is effectively prevented from rotating relative to the mounting groove 111. The number of sides of the adapter block 20 is greater than or equal to six. In this way, the adapter block 20 can slide into the mounting groove 111 from multiple angles. There is no need to make large adjustments to the angle at which the adapter block 20 slides into the mounting groove 111, and the adapter block 20 can be quickly slid into the mounting groove 111.

[0048] Further, see Figure 4 and Figure 5 A groove 22 is provided on the adapter block 20 . When the locking block 32 is in the locking position, part of the locking block 32 is locked into the groove 22 .

[0049] Specifically, when the locking block 32 slides into the mounting groove 111 and is in place, part of the locking block 32 protrudes into the mounting groove 111 through the through opening 114 and is locked in the groove 22 to limit the sliding of the adapter block 20 relative to the mounting groove 111, preventing the adapter block 20 from sliding out of the sliding opening 112, thereby locking the adapter block 20 in the mounting groove 111.

[0050] In one embodiment of this application, see Figures 3 to 5 The rotating member 31 includes a rotating ring 311 and a lever 312. The rotating ring 311 is rotatably arranged in the accommodating cavity 13 and is connected to the locking block 32. One end of the lever 312 is connected to the rotating ring 311, and the other end extends to the outside of the accommodating cavity 13. When the locking block 32 is in the unlocked position, the convex button 41 abuts against the lever 312.

[0051] Specifically, see Figure 1 、 Figure 3 and Figure 4 The side wall of the back plate 12 is provided with a clearance opening 121, which is connected to the accommodating cavity 13. One end of the shift rod 312 is connected to the side wall of the rotating ring 311, and the other end of the shift rod 312 extends to the outside of the accommodating cavity 13 by passing through the clearance opening 121.

[0052] Optionally, the shift rod 312 and the rotating ring 311 are integrally formed.

[0053] See also Figure 3 、 Figure 4 and Figure 6When the locking block 32 is in the unlocked position, the reaction force provided by the convex button 41 to the lever 312 can prevent the lever 312 from rotating in the opposite direction, so that the locking block 32 remains in the unlocked position.

[0054] When the locking block 32 is in the unlocked position, the button 41 abuts against the lever 312 under the action of the first elastic member 42, preventing the lever 312 from rotating in the opposite direction, thereby keeping the locking block 32 in the unlocked position even without external force, freeing both hands and facilitating operation.

[0055] In one embodiment of this application, see Figure 4 and Figure 6 The swivel 311 is movably mounted on the adapter block 20 . The swivel 311 is provided with a guide groove 3111 . The guide groove 3111 is tilted along the circumference of the swivel 311 . The outer wall of the locking block 32 is provided with a boss 321 . The boss 321 is movably inserted into the guide groove 3111 .

[0056] Among them, there are multiple guide grooves 3111, and the multiple guide grooves 3111 are arranged at intervals along the circumference of the rotating ring 311. The number of protrusions 321 is equal to the number of guide grooves 3111, and the multiple protrusions 321 are respectively inserted into the multiple guide grooves 3111 in a one-to-one correspondence.

[0057] Optionally, there are three guide grooves 3111, which are evenly spaced along the circumference of the rotating ring 311. There are also three bosses 321, which are spaced along the outer wall of the locking block 32. The three bosses 321 are respectively inserted into the three guide grooves 3111.

[0058] When the rotating ring 311 is rotated by toggling the toggle rod 312 , the guide groove 3111 guides the boss 321 to move in the guide groove 3111 , thereby driving the locking block 32 to move axially along the rotating ring 311 , so that the locking block 32 approaches or moves away from the adapter block 20 .

[0059] It should be noted that, in other embodiments, other methods can also be used to convert the rotational motion of the swivel 311 into the linear motion of the locking block 32. For example, the locking block 32 and the mounting seat 10 are slidably engaged along the axial direction of the swivel 311. The swivel 311 is sleeved on the locking block 32 and is threadedly engaged with the locking block 32. In this way, when the swivel 311 rotates, it can also drive the locking block 32 to move along the axial direction of the swivel 311, so that the locking block 32 is close to or away from the adapter block 20.

[0060] In one embodiment of this application, see Figure 4 and Figure 5 The locking assembly 30 further includes a second elastic member 33 . The second elastic member 33 is disposed in the accommodating cavity 13 and abuts against a side of the locking block 32 away from the mounting groove 111 .

[0061] Optionally, the second elastic member 33 may be a spring or other elastic component.

[0062] One end of the second elastic member 33 abuts against the side of the locking block 32 away from the mounting groove 111, and the other end of the second elastic member 33 abuts against the back plate 12. When the convex twist releases the restriction on the rotating member 31, the second elastic member 33 can drive the locking block 32 to move from the unlocked position to the locked position, and then drive the locking block 32 to rotate in the opposite direction to the initial position. In this way, after the adapter block 20 slides into the mounting groove 111 and is in place, the locking block 32 can automatically abut against the adapter block 20 under the action of the second elastic member 33, so as to lock the adapter block 20 in the mounting groove 111, which is convenient to use.

[0063] Furthermore, the locking block 32 defines a receiving cavity 322 , and the second elastic member 33 is at least partially accommodated in the receiving cavity 322 .

[0064] Specifically, the receiving cavity 322 passes through a side of the locking block 32 facing away from the installation slot 111 , and a portion of the second elastic member 33 is accommodated in the receiving cavity 322 .

[0065] By at least partially accommodating the second elastic member 33 in the receiving cavity 322 , the receiving cavity 322 can guide the telescopic movement of the second elastic member 33 , thereby effectively preventing the second elastic member 33 from generating lateral deformation.

[0066] In one embodiment of this application, see Figure 4 and Figure 5The lever 312 is arranged on the side of the mounting base 10 away from the mounting groove 111, the mounting base 10 is provided with a movable groove 115, the retaining assembly 40 is accommodated in the movable groove 115, and the first elastic member 42 abuts against the side of the convex button 41 away from the lever 312, so that part of the convex button 41 can protrude out of the movable groove 115 toward the direction of the lever 312.

[0067] Specifically, the movable slot 115 is provided at an edge of the base body 11 and passes through a side of the base body 11 away from the installation slot 111 . The shifting rod 312 is provided on a side of the base body 11 away from the installation slot 111 .

[0068] The first elastic member 42 may be a spring or other elastic components.

[0069] When the locking block 32 is in the locked position, the positions of the lever 312 and the convex button 41 are offset, and the convex button 41 does not abut the lever 312. At this time, under the action of the first elastic member 42, the convex button 41 causes most of the convex button 41 to protrude out of the movable groove 115 toward the lever 312, as shown in FIG. Figure 4 When the locking block 32 is in the unlocked position, the position of the lever 312 corresponds to that of the convex button 41, the convex button 41 abuts against the lever 312, and the convex button 41 is retracted into the movable groove 115 under the action of the lever 312, and the first elastic member 42 is in a compressed state. Figure 5 .

[0070] In one embodiment of this application, see Figure 4 、 Figure 5 and Figure 7 The movable groove 115 is connected to the installation groove 111. The retaining assembly 40 also includes a push block 43 and a third elastic member 44. The push block 43 is movably arranged in the movable groove 115. The push block 43 is provided with a receiving cavity 431 for accommodating the convex button 41 and the first elastic member 42. The third elastic member 44 acts on the push block 43 to make the push block 43 abut against the adapter block 20.

[0071] Specifically, the push block 43 is movable within the movable slot 115, and a portion of the push block 43 can protrude into or out of the mounting slot 111. An accommodating cavity 431 extends through the side of the push block 43 facing the actuating rod 312, allowing the knob 41 to protrude out of the accommodating cavity 431 under the action of the first elastic member 42 to abut against the actuating rod 312.

[0072] The third elastic member 44 can be a spring or other elastic member. The third elastic member 44 abuts against the push block 43 to drive the push block 43 to move toward the installation slot 111.

[0073] When the adapter block 20 slides out of the mounting groove 111, when the adapter block 20 is disengaged from the push block 43, the push block 43 moves toward the mounting groove 111 under the action of the third elastic member 44 and protrudes into the mounting groove 111. At the same time, the push block 43 drives the convex button 41 and the first elastic member 42 to move synchronously, so that the convex button 41 is disengaged from the abutment of the detent rod 312. At the moment when the adapter block 20 completely slides out of the mounting groove 111, the locking block 32 moves from the unlocking position to the locking position under the elastic action of the second elastic member 33, thereby driving the locking block 32 to rotate in the opposite direction to the initial position, and the detent rod 312 returns to a position staggered with the convex button 41. Figure 7 Similarly, when the adapter block 20 slides into the installation groove 111, when the adapter block 20 abuts against the push block 43, the push block 43 retracts into the movable groove 115, and at the same time drives the convex button 41 and the first elastic member 42 to move synchronously, so that most of the convex button 41 protrudes to the side of the base 11 away from the installation groove 111, so that when the position of the detent rod 312 corresponds to that of the convex button 41, the convex button 41 can abut against the detent rod 312 under the action of the first elastic member 42, as shown in FIG. Figure 4 .

[0074] The above technical solution, by providing a push block 43 and a third elastic member 44, when the adapter block 20 is removed from the mounting groove 111, the third elastic member 44 cooperates with the push block 43 to disengage the convex button 41 from the abutment against the detent rod 312, and automatically releases the restriction of the convex button 41 on the detent rod 312, that is, automatically releases the restriction of the retaining assembly 40 on the locking assembly 30, without manual operation, which is convenient for users to use. In addition, when the retaining assembly 40 releases the restriction on the locking assembly 30, the locking block 32 can automatically switch from the unlocked position to the locked position, realizing one-button operation, which is easy to use and helps to improve the user experience.

[0075] In some embodiments of this application, please refer to Figure 4 、 Figure 5 and Figure 7 The retaining assembly 40 also includes a limiting sleeve 45, which is sleeved on the push block 43. The limiting sleeve 45 covers the opening of the accommodating cavity 431 to limit part of the convex button 41 and the first elastic member 42 within the accommodating cavity 431 to prevent the convex button 41 and the first elastic member 42 from escaping from the accommodating cavity 431.

[0076] In some embodiments of this application, please refer to Figure 4 and Figure 5The quick-release structure further includes a retaining ring 50, which is disposed on the side of the base body 11 facing away from the mounting groove 111. The retaining ring 50 blocks the opening of the movable groove 115 to restrict the retaining assembly 40 within the movable groove 115 and prevent the retaining assembly 40 from escaping from the movable groove 115. A third elastic member 44 is sleeved on the limiting sleeve 45, with one end of the third elastic member 44 abutting against the push block 43 and the other end of the third elastic member 44 abutting against the retaining ring 50.
