[0039] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more unless otherwise specifically defined.

[0040] Please refer to Figure 1 and Figure 2 together. Now, the quick-release structure provided by the embodiments of this application will be described. The quick-release structure is used to connect a first device and a second device. The quick-release structure includes a first connecting member 1, a second connecting member 2, a moving member 3, and an elastic member 4. The first connecting member 1 is used to connect to the first device, and a first clamping structure 110 is provided on the first connecting member 1. The second connecting member 2 is used to connect to the second device. The first connecting member 1 can be inserted into the second connecting member 2 along the axial direction, and the first connecting member 1 is restricted from rotating relative to the second connecting member 2 about the axis. The moving member 3 is allowed to rotate relative to the second connecting member 2 about the axis. A limiting structure is provided on the moving member 3, and the limiting structure restricts the moving member 3 from moving axially relative to the second connecting member 2. A second clamping structure 30 for engaging with the first clamping structure 110 is provided on the moving member 3. In a state where the first clamping structure 110 and the second clamping structure 30 are engaged, the first connecting member 1 is restricted from moving axially relative to the moving member 3. The elastic member 4 abuts between the moving member 3 and the second connecting member 2, and the elastic member 4 can drive the moving member 3 to rotate relative to the second connecting member 2 about the axis so that the first clamping structure 110 and the second clamping structure 30 are in an engaged state.

[0041] The first connecting member 1 and the second connecting member 2 are respectively connected to the first device and the second device. The first connecting member 1 and the second connecting member 2 are inserted into each other to limit relative rotation about the axis. The first connecting member 1 and the second connecting member 2 are engaged by the first engaging structure 110 and the second engaging structure 30 to limit the relative axial movement between the first connecting member 1 and the second connecting member 2, so that the first connecting member 1 and the second connecting member 2 are locked to each other. Among them, the second engaging structure 30 is provided on the moving member 3. Since the moving member 3 is restricted from moving axially relative to the second connecting member 2, but can rotate relative to the second connecting member 2 about the axis, the position of the second engaging structure 30 can be moved by rotating the moving member 3, so that the engaging state between the first engaging structure 110 and the second engaging structure 30 can be released, or the second engaging structure 30 can be engaged with the first engaging structure 110. In addition, since the elastic member 4 abuts between the moving member 3 and the second connecting member 2, during the process of inserting the first connecting member 1 into the second connecting member 2, the first engaging structure 110 pushes the second engaging structure 30 to make way. After the first connecting member 1 is inserted in place, the moving member 3 can automatically reset under the elastic action of the elastic member 4 and make the first engaging structure 110 and the second engaging structure 30 tightly engaged. The assembly process can be completed in one step and can be operated with one hand.

[0042] Compared with the prior art, the quick-release structure provided by the present application can engage or disengage the second engaging structure 30 and the first engaging structure 110 by rotating the moving member 3. The moving member 3 can automatically reset under the action of the elastic member 4 and make the first engaging structure 110 and the second engaging structure 30 tightly engaged, improving the structural reliability. The disassembly and assembly process is fast and convenient, without the need to use auxiliary tools and parts. The assembly process can be completed in one step and can be operated with one hand.

[0043] In another embodiment of the present application, please refer to Figures 1 to 3 , the second connecting member 2 is a cylindrical structure, the moving member 3 is a ring structure, one end of the second connecting member 2 is open for the moving member 3 to be sleeved therein, and the bottom of the second connecting member 2 is used to connect to the second device. The first connecting member 1 is a cylindrical structure, and the first connecting member 1 can be inserted into the second connecting member 2. Thus, the moving member 3 can rotate within the second connecting member 2, and when the first connecting member 1 is inserted into the second connecting member 2, it can cooperate with both the first connecting member 1 and the moving member 3 to be locked, making the cooperation structure of the three more compact.

[0044] Further, when the moving member 3 is sleeved within the second connecting member 2, the outer side wall of the moving member 3 can be attached to the inner side wall of the second connecting member 2, thereby guiding the rotation of the moving member 3.

[0045] In another embodiment of the present application, please refer to Figure 2 and Figure 4, a limiting block 20 is provided on the second connecting member 2, and the limiting block 20 is located on the bottom wall of the second connecting member 2. A limiting groove 32 is formed at the bottom of the moving member 3, and the limiting groove 32 can accommodate the limiting block 20 and the elastic member 4 at the same time. When the moving member 3 is sleeved in the second connecting member 2, the limiting block 20 is located in the limiting groove 32. At the same time, the elastic member 4 is located in the limiting groove 32, and both ends of the elastic member 4 are respectively abutted against the limiting block 20 and the groove wall of the limiting groove 32. The elastic member 4 is arranged to have a radian to adapt to the moving track of the moving member 3 rotating around the axis. When the moving member 3 is abutted by the first clamping structure 110, the moving member 3 squeezes the elastic member 4 towards the limiting block 20. When the first clamping structure 110 is aligned with the second clamping structure 30, the elastic member 4 releases elastic force to reset the moving member 3 and clamp the second clamping structure 30 on the moving member 3 with the first clamping structure 110.

[0046] In another embodiment of the present application, the number of the elastic members 4 is at least one, specifically, it can be one, two, three, four, etc. Correspondingly, the numbers of the limiting blocks 20 and the limiting grooves 32 are set correspondingly. In this embodiment, please refer to Figure 3 , there are two elastic members 4, two limiting blocks 20 are provided on the second connecting member 2 at opposite positions, and two limiting grooves 32 are formed at the bottom of the moving member 3 at opposite positions. The two elastic members 4 are respectively located in the two limiting grooves 32. Moreover, when the moving member 3 is sleeved on the second connecting member 2, both of the two limiting blocks 20 are located at the rear side in the rotating direction. For example, when the direction of rotation of the moving member 3 around the axis after being abutted by the first clamping structure 110 is the clockwise direction, the limiting block 20 is located at the rear side in the clockwise direction relative to the elastic member 4 to ensure that the moving member 3 can squeeze the elastic member 4.

[0047] In another embodiment of the present application, the elastic member 4 can specifically be a spring, an elastic rubber strip, etc. In this embodiment, the elastic member 4 is a spring.

[0048] In another embodiment of the present application, please refer to Figure 2 and Figure 3 , a guiding groove 21 for the moving member 3 to insert is provided on the second connecting member 2, and the moving member 3 can rotate around the axis direction in the guiding groove 21.

[0049] Specifically, a protruding boss 22 is provided on the inner bottom wall of the second connecting member 2. The boss 22 is located at the middle position of the bottom. There is a gap between the boss 22 and the side wall of the second connecting member 2, and this gap is the guiding groove 21. The guiding groove 21 is annular. When the moving member 3 is sleeved on the second connecting member 2, the outer side of the moving member 3 can be attached to the inner wall of the second connecting member 2, and the inner side of the moving member 3 can be attached to the side wall of the boss 22.

[0050] In another embodiment of the present application, in order to improve the connection reliability between the first connecting member 1 and the second connecting member 2, a plurality of first clamping structures 110 are provided. Correspondingly, a plurality of second clamping structures 30 are provided, and the plurality of first clamping structures 110 are snap-fitted with the plurality of second clamping structures 30 in one-to-one correspondence.

[0051] Since in the quick-release structure provided by the embodiment of the present application, the second clamping structure 30 is provided on the moving member 3, during the disassembly and assembly process, by simply rotating the moving member 3, the plurality of second clamping structures 30 can be synchronously moved, ensuring the smooth progress of the disassembly and assembly process and improving the disassembly and assembly convenience.

[0052] In this embodiment, the number of the first clamping structures 110 is four, and the corresponding number of the second clamping structures 30 is four. The four first clamping structures 110 are circumferentially and uniformly distributed on the first connecting member 1, and the four second clamping structures 30 are circumferentially and uniformly distributed on the moving member 3.

[0053] In addition, in order to ensure that each second clamping structure 30 can be synchronously displaced when the moving member 3 is rotated, all the second clamping structures 30 are arranged in the same direction. For example, all the second clamping structures 30 are arranged in the clockwise direction. Or, all the second clamping structures 30 are arranged in the counterclockwise direction. The first clamping structures 110 are correspondingly arranged.

[0054] In another embodiment of the present application, referring to Figure 5 and Figure 6 , the first clamping structure 110 is a clamping block 1100, and the second clamping structure 30 is a clamping groove 300. In some other embodiments, the first clamping structure 110 is a clamping groove 300, and the second clamping structure 30 is a clamping block 1100.

[0055] Specifically, the shape of the clamping groove 300 is "L"-shaped. The clamping groove 300 includes an insertion groove 3000 and a clamping groove 3001 that are communicated with each other. The insertion groove 3000 is used for the clamping block 1100 to be axially inserted, and the clamping groove 3001 is used for the clamping block 1100 to be rotationally inserted around the axis and restrict the axial movement of the clamping block 1100. During the process of inserting the first connecting member 1 into the second connecting member 2, the clamping block 1100 pushes the moving member 3 to rotate around the axis, so that the clamping block 1100 can axially enter the insertion groove 3000. Subsequently, the moving member 3 is reset under the action of the elastic member 4, so that the clamping groove 3001 and the clamping block 1100 are tightly clamped together.

[0056] In this embodiment, referring to Figure 5 and Figure 6, the first clamping structure 110 is a clamping block 1100, and the clamping block 1100 protrudes from the side wall of the first connecting member 1. The second clamping structure 30 is a clamping groove 300, and the clamping groove 300 is formed on the peripheral side of the moving member 3. One end of the first connecting member 1 close to the moving member 3 can be inserted into the moving member 3, and the protruding clamping block 1100 can push against the peripheral side of the moving member 3 and be clamped into the clamping groove 300.

[0057] In another embodiment of the present application, please continue to refer to Figure 5 and Figure 6 , a first wedge surface 301 is provided at the notch of the clamping groove 300 close to the engaging groove 3001, and a second wedge surface 1101 for cooperating with the first wedge surface 301 to push is provided on the clamping block 1100.

[0058] During the engagement of the clamping block 1100 and the clamping groove 300, the clamping block 1100 pushes against the notch of the clamping groove 300 (the end face of the moving member 3 facing the first connecting member 1) to rotate the moving member 3 around the axis, and at the same time enters the clamping groove 300 axially. During this process, the first wedge surface 301 can be attached to the second wedge surface 1101 to provide a guiding effect for the movement of the clamping block 1100 and the moving member 3.

[0059] In another embodiment of the present application, please refer to Figure 2 and Figure 3 , a positioning structure is provided between the first connecting member 1 and the second connecting member 2. The positioning structure is used to provide guidance for the axial movement of the first connecting member 1 relative to the second connecting member 2 and to limit the rotation of the first connecting member 1 relative to the second connecting member 2 around the axis.

[0060] By providing the positioning structure, the axial movement of the first connecting member 1 can be restricted, ensuring that the first clamping structure 110 moves axially and smoothly pushes the moving member 3 to rotate. Furthermore, by providing the positioning structure, the relative rotation of the first connecting member 1 and the second connecting member 2 around the axis can be restricted. In addition, during the insertion of the first connecting member 1 into the second connecting member 2, since it is necessary to align the axial positions of the first clamping structure 110 and the second clamping structure 30, the positioning structure can facilitate the alignment of the insertion positions of the first connecting member 1 and the second connecting member 2 at one time.

[0061] In another embodiment of the present application, please refer to Figure 2 and Figure 3 , the positioning structure includes a positioning block 100 and a positioning groove 23. The positioning block 100 is provided on the outside of the first connecting member 1, and the positioning groove 23 is provided on the inner side wall of the second connecting member 2. The positioning block 100 can slide axially in the positioning groove 23.

[0062] Specifically, the first connecting member 1 includes a first section 10 and a second section 11 which are connected to each other. Both the first section 10 and the second section 11 are cylindrical structures. The outer diameter of the first section 10 is larger than that of the second section 11. The first section 10 is used to cooperate with the second connecting member 2, and the second section 11 is used to cooperate with the moving member 3. Therefore, the positioning block 100 is provided on the outer side of the first section 10, and the first clamping structure 110 is provided on the outer side of the second section 11. During the process of inserting the first connecting member 1 into the second connecting member 2, the second section 11 is inserted into the moving member 3, and at the same time, the first clamping structure 110 is in clamping cooperation with the second clamping structure 30. The first section 10 is inserted into the second connecting member 2, and at the same time, the positioning block 100 is in sliding cooperation with the positioning groove 23. After reaching the position, the first section 10 and the moving member 3 are juxtaposed in the first direction.

[0063] In another embodiment of the present application, please refer to Figure 2 , the quick-release structure further includes an unlocking member 5. The unlocking member 5 is connected to the moving member 3, and at least a part of the unlocking member 5 is located outside the second connecting member 2. The operator can indirectly push the moving member 3 to rotate around the axis through the unlocking member 5, so that the second clamping structure 30 is disengaged from the first clamping structure 110.

[0064] In another embodiment of the present application, please refer to Figure 2 , the unlocking member 5 includes a hand-held portion 50 and a connecting portion 51 which are connected to each other. The second connecting member 2 is provided with a through hole 24 for the connecting portion 51 to pass through. One end of the connecting portion 51 passes through the through hole 24 and is connected to the moving member 3. The connecting portion 51 is the above-mentioned limiting structure. The through hole 24 extends along the circumferential direction of the second connecting member 2. The connecting portion 51 can rotate around the axis in the through hole 24, and the hand-held portion 50 is located outside the second connecting member 2.

[0065] Specifically, the connecting portion 51 is fixedly connected to the moving member 3. The fixed connection method can be welding, bonding, bolt fastening, etc., which is not limited here. In this embodiment, the fixed method of the connecting portion 51 and the moving member 3 is: a fixing hole 33 is formed on the side wall of the moving member 3, and one end of the connecting portion 51 is in interference fit with the fixing hole 33 to achieve fixation.

[0066] In another embodiment of the present application, the number of the unlocking members 5 is two, and two through holes 24 are provided. The two through holes 24 are respectively located on the opposite sides of the second connecting member 2. Correspondingly, the two connecting portions 51 are respectively connected to the opposite sides of the moving member 3.

[0067] In another embodiment of the present application, please refer to Figure 1 and Figure 2 , when the clamping block 1100 is located in the clamping groove 3001, there is a moving gap between the connecting portion 51 and the hole wall of the through hole 24 in the direction of rotation around the axis. The moving gap is at least large enough for the connecting portion 51 to move to make the clamping block 1100 withdraw from the clamping groove 3001.

[0068] Specifically, the perforation 24 extends along the circumferential direction of the second connecting member 2 to form an oblong hole. When the clamping block 1100 is located in the engaging groove 3001, assuming that the rotation direction of the clamping block 1100 from the engaging groove 3001 to the insertion groove 3000 is counterclockwise, then at this time the moving member 3 should be able to rotate in the clockwise direction, so that the clamping block 1100 can move from the engaging groove 3001 to the insertion groove 3000. Therefore, the moving gap should be able to allow the connecting portion 51 to rotate clockwise around the axis in the perforation 24, and the moving gap should at least be able to allow the connecting portion 51 to move to make the clamping block 1100 withdraw from the engaging groove 3001.

[0069] In another embodiment of the present application, please refer to Figure 1 and Figure 2 , the hole wall of the perforation 24 abuts against the connecting portion 51 in the axial direction, so that the moving member 3 is restricted from moving axially relative to the second connecting member 2.

[0070] Specifically, along the axial direction, the length of the perforation 24 is the same as the length of the connecting portion 51. Therefore, when the connecting portion 51 is inserted into the perforation 24, the connecting portion 51 is restricted from moving axially by the perforation 24 (that is, the second connecting member 2). Since the connecting portion 51 is fixedly connected to the moving member 3, the moving member 3 is restricted from moving axially relative to the second connecting member 2.

[0071] The present application also provides a photographic device, which includes a first device, a second device, and the quick-release structure provided by the embodiment of the present application. The first connecting member 1 is connected to the first device, and the second connecting member 2 is connected to the second device.

[0072] Specifically, for example, the photographic device is a gimbal, the first device is a gimbal controller, the second device is a bracket. The first connecting member 1 in the quick-release structure is connected to the gimbal controller, and the second connecting member 2 is connected to the bracket. When in use, align the positioning block 100 on the first connecting member 1 with the positioning groove 23 on the second connecting member 2, and move the first connecting member 1 along the first direction towards the second connecting member 2 until the clamping block 1100 is engaged with the clamping groove 300, then the assembly is completed. When disassembly is required, rotate the handheld portion 50 of the unlocking member 5, and pull out the first connecting member 1 to complete the disassembly.

[0073] Another example is that the photographic device is a lamp, the first device is the lamp body, the second device is a bracket. The first connecting member 1 in the quick-release structure is connected to the lamp body, and the second connecting member 2 is connected to the bracket. The disassembly and assembly method is the same as the above example, and will not be repeated here.
