However, most of the extension accessories currently require specific tools for disassembly and replacement, which makes the replacement of extension accessories troublesome and affects shooting efficiency. Utility Model Content

[0003] The purpose of the embodiments of the present application is to provide a quick-release structure and a lens assembly to solve the technical problem of the troublesome disassembly and assembly of the extended accessories in the lens assembly in the prior art.

[0004] To achieve the above-mentioned purpose, the technical solution adopted in the present application is: to provide a quick-release structure for assembling a first structural member and a second structural member, the quick-release structure comprising:

[0005] A fixing member, configured to be fixed to the first structural member;

[0006] A clamping member, rotatably connected to the fixing member, and the clamping member can rotate relative to the fixing member to be clamped to the second structural member;

[0007] A locking member is movably arranged between the fixing member and the clamping member, wherein the locking member limits the relative rotation of the clamping member and the fixing member when the locking member is in a first position, and unlocks the relative rotation of the clamping member and the fixing member when the locking member is in a second position.

[0008] In one embodiment, the locking member is slidably disposed on the clamping member;

[0009] When the locking member is in the first position, the locking member is located on the fixing member to limit the relative rotation between the clamping member and the fixing member;

[0010] When the locking member is at the second position, the fixing member is avoided to unlock the relative rotation between the clamping member and the fixing member.

[0011] In one embodiment, the fixing member has:

[0012] a limiting groove, wherein the locking element is limitedly located in the limiting groove when in the first position;

[0013] An arc groove is connected to the limiting groove, and the arc groove is arranged around the rotation center line of the clamping member; the locking member is slidably arranged in the arc groove when in the second position.

[0014] In one embodiment, the fixing member is formed with a slot, the locking member is inserted into the slot when in the first position, and the locking member retracts into the clamping member when in the second position.

[0015] In one embodiment, the quick-release structure further includes a pressing member connected to the locking member. The pressing member extends to the outside of the fixing member or the clamping member, and pressing the pressing member can drive the locking member to move from the first position to the second position.

[0016] In one embodiment, the quick-release structure further includes a reset member connected to the pressing member or the locking member. The reset member has an elastic pressure for resetting the locking member and the pressing member from the second position to the first position.

[0017] In one embodiment, the clamping member has a receiving groove, a sliding groove, and a guiding groove that are sequentially communicated along the rotation center direction of the clamping member; the reset member is received in the receiving groove, the locking member is slidably disposed in the sliding groove, the pressing member extends from the guiding groove into the receiving groove via the sliding groove, and the pressing member abuts against the reset member.

[0018] In one embodiment, the clamping member is formed with a mounting groove, and at least a part of the fixing member is received in the mounting groove.

[0019] In one embodiment, the clamping member has a first end and a second end that are oppositely arranged along a first direction. The fixing member is received in the first end, and the second end has a clamping portion for clamping the second structural member; the locking member is slidably disposed between the first end and the second end, and the sliding direction of the locking member is parallel to the rotation center direction of the clamping member, and the first direction is perpendicular to the sliding direction of the locking member.

[0020] On the other hand, the present application further provides a lens assembly, including a lens, an extended accessory, and a quick-release structure for realizing the assembly of the lens and the extended accessory.

[0021] The beneficial effects of the quick-release structure and the lens assembly provided by this application are as follows: Through the settings of the fixing member, the clamping member, and the locking member, and the locking member is movably arranged between the fixing member and the clamping member.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more such features. In the description of this application, "a plurality" means two or more unless otherwise specifically defined.

[0039] Please refer to Figure 1 and Figure 2 , an embodiment of this application provides a lens assembly, including a lens 2 and an extension accessory 3. The extension accessory 3 is detachably mounted on the lens 2. The extension accessory 3 is disposed on the light-emitting side of the lens 2 and is used to process the light emitted from the lens 2 to achieve different lighting effects.

[0040] Among them, the extension accessory 3 can be a light-shielding structure, a softbox, or a lens, etc.

[0041] Please refer to Figure 1 and Figure 2 , the quick-release structure 1 provided by the embodiment of this application will now be described. The quick-release structure 1 is used to realize the assembly of a first structural member and a second structural member. In this embodiment, the quick-release structure 1 is mainly used to mount the extension accessory 3 on the lens 2. The first structural member is the lens 2, and the second structural member is the extension accessory 3, or the first structural member is the extension accessory 3 and the second structural member is the lens 2. It can be understood that in other embodiments of this application, the quick-release structure 1 can also be used for the connection of other structures, such as realizing the installation of a lampshade on a lamp body, or realizing the installation of a fan cover on a fan body.

[0042] Please refer to Figures 3 to 6 , the quick-release structure 1 includes a fixing member 100, a clamping member 200, and a locking member 300. The fixing member 100 is set to be fixed to the first structural member; the clamping member 200 is rotatably connected to the fixing member 100, and the clamping member 200 can rotate relative to the fixing member 100 to be clamped to the second structural member; the locking member 300 is movably disposed between the fixing member 100 and the clamping member 200. When the locking member 300 is in the first position, the relative rotation of the clamping member 200 and the fixing member 100 is limited, and when the locking member 300 is in the second position, the relative rotation of the clamping member 200 and the fixing member 100 is unlocked.

[0043] Among them, the locking member 300 is movably disposed between the fixing member 100 and the clamping member 200, and the movement of the locking member 300 can be linear sliding or rotation. When the locking member 300 moves, the locking member 300 can alternately be in the first position and the second position.

[0044] When the locking member 300 is in the first position, the locking member 300 defines the relative rotation of the clamping member 200 and the fixing member 100, that is, the clamping member 200 and the fixing member 100 cannot rotate relative to each other. The clamping member 200 can be maintained in a state of being clamped to the second structural member, that is, the first structural member and the second structural member are kept connected; or the clamping member 200 can be maintained in a state of being separated from the second structural member, that is, the first structural member and the second structural member are kept separated.

[0045] When the locking member 300 is in the second position, the locking member 300 unlocks the relative rotation of the clamping member 200 and the fixing member 100, that is, the clamping member 200 and the fixing member 100 can rotate relative to each other. The clamping member 200 can rotate from a state of being separated from the second structural member to a state of being clamped to the second structural member; the clamping member 200 can also rotate from a state of being clamped to the second structural member to a state of being separated from the second structural member.

[0046] For the quick-release structure 1 in this embodiment, during assembly, only by externally driving the locking member 300 to move from the first position to the second position, the clamping member 200 can be rotated so that the clamping member 200 is clamped to the second structural member; during disassembly, similarly, only by externally driving the locking member 300 to move from the first position to the second position, the clamping member 200 can be rotated so that the clamping member 200 is separated from the second structural member.

[0047] For the quick-release structure 1 in the embodiment of the present application, through the settings of the fixing member 100, the clamping member 200 and the locking member 300, and the locking member 300 is movably arranged between the fixing member 100 and the clamping member 200. When the locking member 300 is in the second position, the relative rotation of the clamping member 200 and the fixing member 100 is unlocked, so that the clamping member 200 can be rotated relative to the fixing member 100 to be clamped to the second structural member to achieve the clamping between the first structural member and the second structural member. When the locking member 300 is in the first position, the relative rotation of the clamping member 200 and the fixing member 100 is defined, so that the clamping member 200 can be maintained in a position clamped to the second structural member to ensure the connection reliability between the first structural member and the second structural member. For the quick-release structure 1 of the present application, during assembly and disassembly, only by externally driving the locking member 300 to move between the first position and the second position, the operation is simple and convenient, and no specific tool is required. When the quick-release structure 1 in the present application is used to realize the assembly between the expansion accessory 3 and the lens 2, it not only makes the disassembly and assembly of the expansion accessory 3 and the lens 2 convenient and fast, but also can ensure the assembly reliability of the expansion accessory 3 on the lens 2.

[0048] In addition, please refer to Figure 1 and Figure 2When the rotation center line O between the clamping member 200 and the fixing member 100 is set to be tangent to the outer contour of the lens 2, the clamping member 200 and the fixing member 100 can be installed on the outer surface of the cylindrical lens 2 and the extension accessory 3 to achieve the assembly between the lens 2 and the extension accessory 3, without installing the quick release structure 1 inside the lens 2 or the extension accessory 3, thereby simplifying the structural design of the lens 2 and the extension accessory 3. Figure 8 Shown by the dashed line.

[0049] In one embodiment, the locking member 300 is slidably disposed on the clamping member 200. When the locking member 300 is in the first position, it is limited to the fixing member 100 to limit the relative rotation of the clamping member 200 and the fixing member 100. When the locking member 300 is in the second position, it avoids the fixing member 100 to unlock the relative rotation of the clamping member 200 and the fixing member 100.

[0050] During assembly, the locking member 300 is manually slid from the first position to the second position, and then the clamping member 200 is rotated relative to the fixing member 100 to be clamped on the second structural member. After clamping, the locking member 300 is slid from the second position to the first position so that the clamping member 200 remains clamped on the second structural member.

[0051] In this embodiment, it is only necessary to slide the locking member 300 so that a structural limit or structural avoidance is formed between the locking member 300 and the fixing member 100, so as to limit or unlock the relative rotation between the clamping member 200 and the fixing member 100, which is convenient for operation. It can be understood that in other embodiments of the present application, the locking member 300 can also be rotatably arranged in the clamping member 200; or the locking member 300 can also be slidably or rotatably arranged on the fixing member 100, and a structural limit or structural avoidance is formed between the locking member 300 and the clamping member 200, so as to limit or unlock the relative rotation between the clamping member 200 and the fixing member 100, which is not the only limitation here.

[0052] In one embodiment, see Figures 6 to 8 The fixing member 100 has a limiting groove 110 and an arc groove 120, the arc groove 120 is connected to the limiting groove 110, and the arc groove 120 is arranged around the rotation center line O of the clamping member 200; the locking member 300 is limited in the limiting groove 110 when in the first position; and the locking member 300 is slidably arranged in the arc groove 120 when in the second position. Figure 8 Shown by the dashed line.

[0053] Specifically, the locking member 300 can slide in the clamping member 200. When the locking member 300 slides to the first position, the locking member 300 is limited in the limiting groove 110, so as to limit the relative rotation between the clamping member 200 and the fixing member 100. When the locking member 300 slides to the second position, the locking member 300 is arranged corresponding to the arc-shaped groove 120. Since the arc-shaped groove 120 is arranged around the rotation center line O of the clamping member 200, when the clamping member 200 rotates around the rotation center line O, the locking member 300 also rotates around the rotation center line O, and the part of the locking member 300 corresponding to the arc-shaped groove 120 slides in the arc-shaped groove 120. At this time, the locking member 300 forms a structural avoidance with the fixing member 100 through the arc-shaped groove 120, thereby unlocking the relative rotation between the clamping member 200 and the fixing member 100. In this embodiment, by forming the arc-shaped groove 120 on the fixing member 100, it is realized that when the locking member 300 is in the second position, it can slide in the arc-shaped groove 120 to avoid the fixing member 100, thereby unlocking the relative rotation between the fixing member 100 and the clamping member 200. The structure is simple and easy to process. It can be understood that in other embodiments, the limiting groove 110 and the arc-shaped groove 120 can also be formed in the clamping member 200, and this is not the only limitation here.

[0054] In one embodiment, please refer to Figures 6 to 9 , the clamping member 200 is formed with a sliding groove 212 with an opening facing the fixing member 100. The opening of the limiting groove 110 faces the clamping member 200, and the opening of the arc-shaped groove 120 faces the outer peripheral surface of the fixing member 100, and the opening of the arc-shaped groove 120 at least partially faces the clamping member 200. One end of the locking member 300 is slidably arranged in the sliding groove 212 of the clamping member 200, and the other end of the locking member 300 is slidably arranged between the limiting groove 110 and the arc-shaped groove 120.

[0055] In one embodiment, please refer to Figure 6 and Figure 9 , the sliding direction of the locking member 300 is arranged parallel to the rotation center line O of the clamping member 200. A clamping portion 214 is provided at one end of the clamping member 200 away from the rotation center line O, and the clamping portion 214 is clamped on the second structural member. The above arrangement makes the sliding operation of the locking member 300 not interfere with the clamping portion 214 of the clamping member 200. Of course, in other embodiments, the sliding direction of the locking member 300 can also be arranged at an angle with the rotation center line O of the clamping member 200, and this is not the only limitation here.

[0056] In one embodiment, please refer to Figures 3 to 6, the quick-release structure 1 further includes a pressing member 400. The pressing member 400 is connected to the locking member 300 and extends to the outside of the fixing member 100 or the clamping member 200. Pressing the pressing member 400 can drive the locking member 300 to move from the first position to the second position. Among them, through the setting of the pressing member 400, it is possible to press the pressing member 400 externally to drive the locking member 300 to move from the first position to the second position, and the operation is simple and convenient.

[0057] In a specific embodiment, please refer to Figure 6 , the locking member 300 is slidably disposed in the clamping member 200. One end of the pressing member 400 extends into the clamping member 200 to be connected to the locking member 300, and the other end of the pressing member 400 extends out of the clamping member 200 for the user to press and drive.

[0058] In a specific embodiment, the pressing member 400 is in the shape of a long rod, and the length extension direction of the pressing member 400 is parallel to the rotation center line O of the clamping member 200, that is, the end of the pressing member 400 far from the locking member 300 extends to the outside of one side of the clamping member 200 along the rotation center line O. Such a setting makes the clamping portion 214 of the pressing member 400 and the clamping member 200 not interfere with the structure and is convenient for the user to operate.

[0059] In one embodiment, the pressing member 400 is threadedly connected to the locking member 300. In this way, the pressing member 400 and the locking member 300 are convenient to disassemble and assemble, and the connection is reliable, so that the pressing member 400 and the locking member 300 can slide synchronously. It can be understood that in other embodiments of the present application, the pressing member 400 and the locking member 300 can also be synchronously slid by welding, clamping, or step limiting. In addition, the pressing member 400 and the locking member 300 can also be set as an integral connection structure, that is, another part of the locking member 300 is directly extended to the outside of the clamping member 200 for the user to drive, and this is not limited uniquely here.

[0060] In one embodiment, please refer to Figure 5 and Figure 6 , the quick-release structure 1 further includes a reset member 500. The reset member 500 is connected to the pressing member 400, and the reset member 500 has an elastic pressure for resetting the locking member 300 and the pressing member 400 from the second position to the first position. It can be understood that in other embodiments, the reset member 500 can also be directly abutted against the locking member 300, and this is not limited uniquely here.

[0061] Specifically, due to the setting of the reset member 500, the locking member 300 is held at the first position, that is, the engaging member 200 and the fixing member 100 are held in a non-rotatable relative state. When assembling the second structural member with the first structural member, the pressing member 400 is pressed to cause the locking member 300 to slide from the first position to the second position, so that the engaging member 200 can rotate relative to the fixing member 100 to be engaged with the second structural member, and at this time the reset member 500 is compressed and stores elastic force. After the assembly is completed, the pressing member 400 is released, and the pressing member 400 and the locking member 300 automatically reset to the first position under the elastic pressure of the reset member 500, so that the second structural member remains in the engaged state, which is convenient to operate.

[0062] In one embodiment, please refer to Figure 6 and Figure 9 , the engaging member 200 has a receiving groove 211, a sliding groove 212, and a guiding groove 213 that are sequentially communicated along the rotation center direction of the engaging member 200; the reset member 500 is received in the receiving groove 211, the locking member 300 is slidably disposed in the sliding groove 212, the pressing member 400 extends into the receiving groove 211 from the guiding groove 213 through the sliding groove 212, and the pressing member 400 abuts against the reset member 500.

[0063] When assembling the quick-release structure 1, the reset member 500 is loaded into the receiving groove 211, the locking member 300 is loaded into the sliding groove 212, and then the pressing member 400 is inserted into the receiving groove 211 from the guiding groove 213 through the sliding groove 212, so that the reset member 500 abuts against one end of the pressing member 400, and the other end of the pressing member 400 extends out of the engaging member 200 from the guiding groove 213 for the user to drive.

[0064] When assembling the second structural member, it is only necessary to press the pressing member 400 along the rotation center direction of the engaging member 200 outside the engaging member 200. The above structural design not only makes the quick-release structure 1 convenient to operate, but also makes the quick-release structure 1 simple in structure and simple in assembly, and does not cause structural interference with the engaging portion 214 of the engaging member 200.

[0065] In a specific embodiment, please refer to Figure 6 , the receiving groove 211 penetrates through one end of the engaging member 200 facing away from the guiding groove 213, a locking nut 600 is installed at one end of the receiving groove 211 facing away from the guiding groove 213, and the reset member 500 abuts between the locking nut 600 and the pressing rod.

[0066] In a specific embodiment, please refer to Figure 6 , the caliber of the sliding groove 212 is larger than that of the receiving groove 211, and the caliber of the sliding groove 212 is larger than that of the guiding groove 213. The opening of the sliding groove 212 faces the fixing member 100, and the locking member 300 can slide in the sliding groove 212.

[0067] In a specific embodiment, please refer to Figure 6 , the pressing member 400 includes an axially connected connecting section 410 and a guiding section 420. The outer diameter of the connecting section 410 is smaller than that of the guiding section 420. The connecting section 410 is disposed in the sliding groove 212 and the receiving groove 211. The connecting section 410 is provided with an external thread, and the locking member 300 is threadedly sleeved on the connecting section 410; the guiding section 420 is slidably disposed in the guiding groove 213, and the guiding section 420 and the guiding groove 213 form a sliding guide for the pressing member 400.

[0068] During assembly, first, the locking member 300 is inserted into the sliding groove 212 from the opening of the sliding groove 212; then, the connecting section 410 of the pressing member 400 is rotated through the locking member 300 and extends into the receiving groove 211; then, the reset member 500 is inserted into the receiving groove 211; finally, the locking nut 600 is tightened at the opening of the receiving groove 211 so that the reset member 500 abuts against the locking nut 600 and the connecting section 410 of the pressing member 400.

[0069] In addition, please refer to Figure 6 , one end of the guiding section 420 departing from the connecting section 410 is further connected with a holding portion 430. The outer diameter of the holding portion 430 is larger than that of the guiding section 420, and the holding portion 430 abuts against the outside of the engaging member 200. The user can drive the pressing member 400 by holding the holding portion 430.

[0070] In an embodiment, please refer to Figure 5 and Figure 6 , the quick-release structure 1 further includes a rotating shaft 700, and the engaging member 200 and the fixing member 100 are rotatably connected through the rotating shaft 700.

[0071] Specifically, please refer to Figure 8 and Figure 9 , along the axial direction of the rotating shaft 700, two relatively arranged first mounting holes 130 are formed on the fixing member 100. Opposite ends of the engaging member 200 have second mounting holes 221. The two rotating shafts 700 are respectively mounted in the two first mounting holes 130, and the engaging member 200 is rotatably disposed on the two rotating shafts 700 through the two second mounting holes 221 respectively, so as to realize the rotation of the engaging member 200 on the fixing member 100. It can be understood that in other embodiments of the present application, only one rotating shaft 700 may be provided, and the rotating shaft 700 is axially penetrated through the fixing member 100. Here, the rotating shaft 700 may also be fixed on the fixing member 100, and then the rotating shaft 700 is rotatably connected with the engaging member 200, and this is not limited uniquely.

[0072] In an embodiment, please refer to Figure 6 and Figure 9The clamping member 200 is formed with an installation groove 230, and the fixing member 100 is at least partially received in the installation groove 230. By receiving the fixing member 100 in the clamping member 200, the connection stability between the fixing member 100 and the clamping member 200 can be improved, and the occupied area of the fixing member 100 and the clamping member 200 can also be reduced, so that the overall appearance of the quick-release structure 1 is neat and beautiful.

[0073] For details, please refer to Figure 6 and Figure 9 The clamping member 200 has a first end 240 and a second end 250 that are arranged opposite to each other along the first direction X. The fixing member 100 is received in the first end 240, and the second end 250 has a clamping portion 214 that is clamped to the second structural member. The locking member 300 is slidably arranged between the first end 240 and the second end 250, and the sliding direction of the locking member 300 is parallel to the rotation center direction Z of the clamping member 200, and the first direction X is perpendicular to the sliding direction of the locking member 300. The above arrangement enables the transition structure of the fixing member 100 and the clamping member 200 and the clamping portion 214 of the clamping member 200 to be located at opposite ends of the clamping member 200 along the first direction X, respectively, and the first direction X is perpendicular to the axial direction of the rotating shaft 700, thereby reducing structural interference.

[0074] Specifically, the installation groove 230 passes through the end surface of the first end 240 of the clamping member 200, and the fixing member 100 is inserted into the installation groove 230 from the opening of the installation groove 230. The fixing member 100 is rotatably connected to the side wall of the clamping member 200 through the rotating shaft 700 at the opposite ends along the rotation center direction of the clamping member 200. The second end 250 of the clamping member 200 has a clamping portion 214, which is used to be clamped to the second structural member.

[0075] In one embodiment, see Figures 2 to 6 and Figure 9 , the fixing member 100 is locked and fixed to the outer wall of the first structural member by the fastener 800. Specifically, the mounting groove 230 passes through the two opposite sides of the clamping member 200 along the second direction Y, and the fixing member 100 is attached to the outer wall of the first structural member on one side along the second direction Y, and is locked on the first structural member by the fastener 800. The second direction Y is perpendicular to the first direction X, and the second direction Y is a direction perpendicular to the radial direction of the first structural member.

[0076] In one embodiment, see Figure 6 Along the first direction X, the pressing member 400, the locking member 300 and the reset member 500 are located between the rotating shaft 700 and the clamping portion 214, so that the various structures on the clamping member 200 are distributed along the length direction of its rotating arm, so that the rotating arm of the clamping member 200 is long enough, the lever principle can be utilized, the operation is labor-saving, and the clamping is secure.

[0077] In one embodiment, please refer to Figure 6 and Figure 9 , the snap-in member 200 includes a main body portion 210 and two lugs 220. The two lugs 220 are respectively located on one side of the main body portion 210 along the first direction X. The two lugs 220 are spaced apart along the axial direction of the rotating shaft 700. The main body portion 210 and the two lugs 220 jointly enclose to form the above-mentioned mounting groove 230. The two rotating shafts 700 are respectively passed through the two lugs 220, so that the fixing member 100 is rotatably arranged on the snap-in member 200. The pressing member 400, the locking member 300 and the reset member 500 are all arranged on the main body portion 210. The snap-in portion 214 is arranged on the side of the main body portion 210 away from the lugs 220.

[0078] In one embodiment, please refer to Figure 1 and Figure 2 , the first structural member is cylindrical, and at least the part of the second structural member connected to the first structural member is cylindrical. For example, the first structural member is a lens 2 (such as a Fresnel lens), the second structural member is an extension accessory 3 (such as a shutter), and the part of the extension accessory 3 connected to the lens 2 is a connecting portion 31, and the connecting portion 31 is cylindrical. A flange 311 extends on the outer periphery of the connecting portion 31, and the snap-in portion 214 of the snap-in member 200 is snap-connected to the flange 311.

[0079] In another embodiment of the present application, the locking member 300 can also be installed between the snap-in member 200 and the fixing member 100 in other ways. Specifically, please refer to Figure 10 , the fixing member 100 is formed with a slot 140. When the locking member 300 is in the first position, it is inserted into the slot 140. When the locking member 300 is in the second position, it retracts into the snap-in member 200. Wherein, when the locking member 300 is inserted into the slot 140, the locking member 300 and the fixing member 100 form a structural limit. When the locking member 300 retracts into the snap-in member 200, the locking member 300 and the fixing member 100 form a structural avoidance.

[0080] In addition, please refer to Figure 10 , a reset member 500 is abutted between the locking member 300 and the snap-in member 200. The reset member 500 is used to keep the locking member 300 inserted into the slot 140, so as to keep the locking member 300 in the first position.

[0081] The above are only the preferred embodiments of the present application, and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
