Description

Technical Field

[0001] This utility model relates to the field of photographic equipment technology, and in particular to a quick-release component, photographic accessories and disassembly kit. Background Technology

[0002] In the field of photographic equipment, with the continuous development of photographic technology and the increasing diversification of user needs, the expansion and realization of various functions in the photographic process increasingly rely on the collaborative work between different devices. The foundation of this collaborative work is the effective connection between different devices.

[0003] Taking common photography scenarios as an example, the camera stand, as the basic support equipment of the entire shooting system, plays a crucial role. In order to enrich shooting functions and meet the diverse shooting needs of users in different environments and shooting requirements, camera stands often need to be equipped with various functional devices, such as fill lights, microphones, etc.

[0004] In this process, the connecting components undoubtedly become the key elements for connecting the camera bracket and functional devices, and their performance directly affects the stability and reliability of the entire shooting system. However, existing connecting components on the market currently have many problems. From a structural design perspective, existing connecting components are complex in structure, and these complex connecting components are prone to slippage during actual use. Once slippage occurs, the connection between the devices becomes unstable. During shooting, functional devices may shake or even fall off due to unstable connections, resulting in problems such as blurry or shaky images, seriously affecting shooting stability and image quality. Utility Model Content

[0005] The main purpose of this invention is to propose a quick-release assembly, which aims to solve the technical problem that the connection between components in current photographic equipment is not stable enough.

[0006] To achieve the above objectives, this utility model proposes a quick-release assembly for photographic accessories. The quick-release assembly includes a connecting module and a claw, a control component, and a first reset component disposed on the connecting module.

[0007] The claw is detachably mounted on the connecting module and is used to hold or release the connecting member.

[0008] The control component is movably connected to the connection module. The control component has a locking position and an unlocking position on its movement path. The control component is used to switch to the locking position to act on the claw, so that the claw closes to hold the connector, or to switch to the unlocking position to cancel the action of the claw, so that the claw can open to release the connector.

[0009] The first reset member acts on the control member and applies an elastic force to the control member to reset it.

[0010] In some embodiments, the claw includes two claw portions, which are arranged at a distance from each other and are rotatably connected to the connecting module. The two ends of the claw portions are a clamping end and a pressing end, respectively. The clamping end is used to clamp the connecting member, and the pressing end is used to be squeezed by the control member.

[0011] When the control element is switched to the locked position, it squeezes the pressure end, causing the claw portion to rotate and drive the holding end to clamp the connector. Alternatively, when the control element is switched to the unlocked position, it releases the pressure end, allowing the claw portion to rotate and driving the holding end to release the connector.

[0012] In some embodiments, the control member includes a rotating part and a pressure part connected to or integrally formed with the rotating part. The rotating part is rotatably connected to the connecting module and located between the two claw parts. The pressure part is located on the periphery of the rotating part and is used to rotate with the rotating part to press the pressure end in the locked position or release the pressure end in the unlocked position.

[0013] In some embodiments, the control element further includes a control lever, which is located on the periphery of the rotating part and connected to or integrally formed with the rotating part. The control lever is used to drive the rotating part to rotate when subjected to an external force.

[0015] Both of the aforementioned claw portions are rotatably connected to the first half-shell, and the pressure-receiving end of the claw portion is located inside the receiving cavity, while the holding end of the claw portion extends out of the receiving cavity;

[0016] The rotating part is located within the receiving cavity and is rotatably connected to at least one of the first half-shell and the second half-shell; the pressure-applying part is located within the receiving cavity.

[0017] One end of the control lever is located inside the receiving cavity, and the other end of the control lever extends out from the first half-shell and / or the second half-shell.

[0018] In some embodiments, the first half-shell is provided with a receiving groove, which extends about the rotation axis of the rotating part;

[0019] The control component also includes a connecting portion that extends into the receiving groove, the connecting portion being located in the circumferential direction of the rotating part and being movably disposed with the rotating part;

[0020] The first reset member includes a spring, which is housed in the receiving groove. One end of the spring is connected to the groove wall at one end of the receiving groove, and the other end of the spring is connected to the connecting part.

[0021] In some embodiments, the rotating part is provided with a mounting hole, a limiting member, and a second resetting member. The mounting hole is located around the rotation axis of the rotating part. The limiting member is slidably disposed in the mounting hole and can extend or retract from the mounting hole. The second resetting member is disposed in the mounting hole and is located between the limiting member and the bottom wall of the mounting hole. The second resetting member acts on the limiting member and is used to apply an elastic force to the limiting member to reset it.

[0022] The first half-shell is provided with a limiting hole, and a pushing member is provided in the limiting hole for sliding cooperation with it. The pushing member can extend or retract from one end of the limiting hole.

[0023] The limiting hole is located on the rotation path of the limiting member. The limiting member can extend into the limiting hole from one end opening under the elastic force of the second reset member to form a stop limit on the rotating part. The pushing member can push the limiting member out of the limiting hole by retracting into the limiting hole to cancel the stop limit on the rotating part.

[0024] In some embodiments, the rotating part is provided with a shaft hole, and the inner wall of the second half shell is provided with a connecting shaft, which is inserted into the shaft hole so that the rotating part is rotatably connected to the second half shell.

[0025] The connecting shaft is provided with a connecting hole, which extends along the axial direction of the connecting shaft and penetrates the outer wall of the second half-shell.

[0026] In some embodiments, the connection module is provided with a magnetic attraction structure, which is used to generate a magnetic attraction force on the pressure end of the claw portion, and the direction of the magnetic attraction force is the same as the direction in which the control member squeezes the pressure end.

[0027] This utility model also proposes a photography accessory, wherein the photography accessory includes an accessory body and a quick-release assembly as described above, and the connecting module is connected to the accessory body.

[0028] This utility model also proposes a disassembly kit, wherein the disassembly kit includes connectors and photographic accessories as described above.

[0029] In some embodiments, the connecting module can slide relative to the connector along the length direction of the connector;

[0030] The connector is provided with multiple positioning grooves, which are spaced apart along the length of the connector. The connecting module is provided with positioning protrusions, which are used to engage with the positioning grooves to position the connecting module.

[0031] The quick-release assembly provided by this utility model can be connected to a connector to achieve connection between different components in photographic equipment.

The first component is connected to the quick-release assembly, and the connector can be the second component to be connected, or it can be an intermediate component connected to the second component. When using this quick-release assembly, the user can easily and quickly lock and release the connector by switching the control component between the locked and unlocked positions. When the control component is switched to the locked position, it will act on the connector, causing the connector to close and lock the connector, ensuring the stability of the connection between the components of the photographic equipment, preventing the components from shaking or falling off due to unstable connection, thereby ensuring the stability of shooting and avoiding problems such as blurry or shaky images.

Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0042] This utility model embodiment provides a quick-release component 1 for photographic accessories, see reference. Figure 1 and Figure 2 The quick-release assembly 1 includes a connecting module 11 and a claw, a control component 13, and a first reset component 14 disposed on the connecting module 11;

[0043] The claw 12 is detachably mounted on the connecting module 11 and is used to hold or release the connecting piece 2.

[0044] The control element 13 is movably connected to the connection module 11. The control element 13 has a locking position and an unlocking position on its movement path. The control element 13 is used to switch to the locking position to act on the claw 12, so that the claw 12 closes to hold the connector 2, or to switch to the unlocking position to cancel the action of the claw 12, so that the claw 12 can open to release the connector 2.

[0045] The first reset member 14 acts on the control member 13 and applies an elastic force to the control member 13 to reset it.

[0046] The quick-release assembly 1 involved in this embodiment is applied to photographic equipment to realize the connection between components in the photographic equipment. The quick-release assembly 1 can be connected to the connector 2. In practical applications, two components in the photographic equipment can be connected through the connection of the quick-release assembly 1 and the connector 2. Specifically, taking the first component and the second component in the photographic equipment as an example, the first component is connected to the quick-release assembly 1. The connection method can include screw connection, snap-fit ​​connection, etc., which are not limited in this embodiment. For example, such as... Figure 1 As shown, the quick-release assembly 1 has a connection hole 1121K on its connection module 11 for connecting a first device. The first device can be a functional device such as a fill light or microphone, but is not limited to these. The connecting piece 2 can be the second device to be connected; that is, the first device is connected to the quick-release assembly 1, and the quick-release assembly 1 is connected to the connecting piece 2 (i.e., the second device), thus achieving the connection between the two devices. Alternatively, the connecting piece 2 can also serve as an intermediate component connected to the second device. The connection method can include screw connections, snap-fit ​​connections, etc., meaning the first device is connected to the quick-release assembly 1, the second device is connected to the connecting piece 2, and the quick-release assembly 1 is connected to the connecting piece 2, thus achieving the connection between the two devices. The second device can be such as a camera stand, but is not limited to these.

[0047] In the quick-release assembly 1, the connecting module 11 serves as the basic load-bearing component, providing a foundation for the installation and connection of other components. The claw 12 engages with the connecting module 11 through a movable connection, allowing it to move within a certain range. This movable connection can be, for example, a sliding connection, a rotating connection, or other similar methods. The movable connection of the claw 12 allows it to move relative to the connecting module 11 as needed, achieving opening and closing actions to accommodate connectors 2 of different sizes and to clamp them. For example, the claw 12 can be rotatably connected to the connecting module 11, and can rotate around the connection point at a certain angle, thereby achieving opening and closing.

[0048] Furthermore, the control element 13 and the first reset element 14, as key components for switching between the locked and unlocked states of the quick-release assembly 1, control the opening and closing state of the claw 12 by applying and releasing mechanical force. The control element 13 is movably connected to the connecting module 11, including rotational and sliding connections, but not limited to these. This movable connection allows the control element 13 to switch positions on the connecting module 11. Specifically, the control element 13 can be movably switched to the locked position. When in the locked position, it can press the claw 12, applying pressure. When the control element 13 acts on the claw 12 and applies pressure, the claw 12 closes under pressure, using friction and clamping force to firmly fix the connecting member 2. Simultaneously, the control element 13 can also be movably switched to the unlocked position, releasing the claw 12 and canceling the pressure. When the control element 13 releases its action on the claw 12 and releases the pressure, the claw 12 opens backward under its own elastic restoring force or a small external force, thus releasing the connecting member 2. The first reset element 14 acts on the control element 13, and its main function is to provide the control element 13 with an elastic force to reset its movement. Furthermore, the presence of this elastic force ensures that the control element 13 can automatically remain in the locked position without external intervention, thereby guaranteeing the stable holding of the pawl 12 on the connecting element 2. The first reset element 14 can be a tension spring, compression spring, or coil spring, etc., and can be specifically set according to actual needs.

[0049] The control component 13 may contain mechanical transmission structures, such as cam transmission or lever transmission. Taking cam transmission as an example, the rotation of the cam changes the position of its contact point with the pawl 12, using this change in cam profile to drive the pawl 12. Lever transmission, on the other hand, amplifies and transmits the force applied to one end of the lever to the pawl 12 through the lever's lever arm principle, thus enabling the pawl 12 to move. These are merely examples and not limiting; the control component 13 can also have other structural forms.

[0050] Locking process:

[0051] First, the photographic device to be connected is mounted on the connector 2 via the quick-release assembly 1. Then, the control member 13 is subjected to a force (such as the elastic force of the first reset member 14), causing it to move towards the locking position and begin acting on the jaw 12. Under the action of the control member 13, the jaw 12 gradually closes towards the center. As the jaw 12 closes, the space in the middle of the jaw 12 gradually decreases until the jaw 12 is in close contact with the connector 2. Through friction and clamping force, the connector 2 is firmly clamped, completing the locking connection between the quick-release assembly 1 and the connector 2. Furthermore, the elastic force continuously applied by the first reset member 14 to the control member 13 ensures that the control member 13 always maintains its action on the jaw 12, thereby maintaining the stable clamping state of the jaw 12 on the connector 2.

[0052] Unlocking process:

[0053] When it is necessary to disassemble the camera device, the control member 13 is operated in reverse, moving towards the unlock position and releasing its effect on the claw 12. At this time, the claw 12 opens backward under its own automatic movement or a small external force (such as the user gently prying open the claw 12 manually). As the claw 12 opens, the space in the middle of the claw 12 gradually increases, causing the clamping force between the quick-release component 1 and the connector 2 to disappear. At this time, the quick-release component 1 and the connector 2 can be easily separated, completing the unlocking process.

[0054] Based on the need for stable connection of components in photographic equipment, the quick-release assembly 1 achieves stable clamping and rapid assembly / disassembly of the connector 2 through the coordinated operation of the connection module 11, the jaws 12, the control component 13, and the first reset component 14. Specifically, the operation of the control component 13 on the jaws 12 controls the clamping force of the jaws 12 on the connector 2, thereby switching between the locked and unlocked states of the quick-release assembly 1.

[0055] When using this quick-release component 1, the user can easily and quickly engage and disengage the latch 12 onto the connector 2 by switching the control element 13 between the locked and unlocked positions. When the control element 13 is switched to the locked position, it engages the latch 12, causing it to close and hold the connector, ensuring the stability of the connection between the components of the photographic equipment. This prevents the components from shaking or falling off due to unstable connections, thus ensuring shooting stability and avoiding problems such as blurry or shaky images.

[0056] In some embodiments, refer to Figures 2 to 4 The claw 12 includes two claw parts 121, which are arranged at intervals relative to each other and are rotatably connected to the connecting module 11. The two ends of the claw parts 121 are respectively the holding end 1211 and the pressing end 1212. The holding end 1211 is used to hold the connecting member, and the pressing end 1212 is used for the operating member 13 to squeeze.

[0057] When the control member 13 switches to the locked position, it squeezes the pressure end 1212, causing the claw part 121 to rotate and drive the holding end 1211 to clamp the connector 2. Or when it switches to the unlocked position, it releases the pressure end 1212, allowing the claw part 121 to rotate and drive the holding end 1211 to release the connector 2.

[0058] In this embodiment, the claw 12 employs two opposing and spaced-apart claw portions 121, both of which are rotatably connected to the connecting module 11. This design provides a basis for the flexible opening and closing of the claw 12. One end of the claw portion 121 is designed as a holding end 1211 specifically for clamping the connector 2, and the holding end 1211 is roughly hook-shaped, while the other end is a pressure end 1212. This clear functional division enables the claw 12 to efficiently perform clamping and releasing operations on the connector 2 throughout the operation of the quick-release assembly 1.

[0059] When it is necessary to connect and lock the quick-release assembly 1 to the connector 2, the connector 2 is first placed between the two claw portions 121. Subsequently, the control member 13 is subjected to a force (such as the elastic force of the first reset member 14) and moves from the initial position to the locked position. As the control member 13 switches to the locked position, it contacts the pressure end 1212 of the claw portion 121 and begins to apply a compressive force. According to the lever principle, the claw portion 121 uses its rotational connection point with the connecting module 11 as the fulcrum. After the pressure end 1212 is subjected to compressive force, the holding end 1211 rotates in opposite directions around the fulcrum. During this process, the holding ends 1211 of the two claw portions 121 gradually move closer to each other and finally tightly clamp the connector 2. At the same time, the first reset member 14 undergoes elastic deformation and releases elastic potential energy during the movement of the control member 13 to the locked position. When the control member 13 reaches the locked position, the first reset member 14 continuously applies an elastic force toward the locked position to the control member 13 to ensure that the control member 13 always maintains a squeezing force on the pressure end 1212 of the claw part 121, thereby maintaining the stable clamping state of the claw part 121 on the connector 2.

[0060] When it is necessary to disassemble the quick-release assembly 1 and the connector 2, that is, to release the clamping force of the claw 121 on the connector 2, an external force opposite to the locking process is applied to the control member 13, causing the control member 13 to move from the locked position to the unlocked position against the elastic force of the first reset member 14. As the control member 13 moves, the squeezing force on the pressure end 1212 of the claw 121 gradually decreases until it disappears. At this time, under the action of its own weight (if the weight of the claw 121 is sufficient to overcome the rotational resistance) or other external forces, the claw 121 rotates around the fulcrum of the rotational connection point with the connecting module 11, and the clamping end 1211 rotates in the opposite direction, thereby gradually releasing the clamping force on the connector 2. During this process, the first reset member 14 undergoes elastic deformation and accumulates elastic potential energy.

[0061] Through the coordinated action of the control element 13 and the first reset element 14, in the locked state, a continuous and stable squeezing force can be applied to the pressure end 1212 of the claw portion 121, ensuring that the claw portion 121 firmly clamps the connector 2, making the connection between components more stable during the use of photographic equipment. The design of the control element 13 allows users to switch between the locked and unlocked states of the quick-release component 1 through simple operations (such as flicking or pressing). Meanwhile, the automatic reset function of the first reset element 14 reduces extra steps for the user during operation; the user does not need to manually reset the control element 13 to the locked position, making operation smoother and more efficient.

[0062] In some embodiments, refer to Figures 3 to 6 The control member 13 includes a rotating part 131 and a pressure part 132 connected to or integrally formed with the rotating part 131. The rotating part 131 is rotatably connected to the connecting module 11 and is located between the two claw parts 121. The pressure part 132 is located on the periphery of the rotating part 131. The pressure part 132 is used to rotate with the rotating part 131 to press the pressure end 122 in the locked position or release the pressure end 122 in the unlocked position.

[0063] Specifically, the rotating part 131, as the core rotating component of the control element 13, is rotatably connected to the connecting module 11. This connection can be achieved through a specific rotating pair, such as a common pin connection or bearing connection, ensuring that the rotating part 131 can rotate flexibly and stably on the connecting module 11. The design of the rotating part 131 provides the rotational basis for the operation of the entire control element 13, enabling other components to perform corresponding functions as it rotates. Specifically, the rotating part 131 can be located between the pressure ends 1212 of the two jaw parts 121.

[0064] The pressure-applying part 132 is connected to or integrally formed with the rotating part 131. The main function of the pressure-applying part 132 is to switch positions as the rotating part 131 rotates, thereby performing a squeezing or releasing operation on the pressure-receiving end 1212 of the claw part 121. The shape and size of the pressure-applying part 132 are specifically designed according to the structure of the pressure-receiving end 1212 of the claw part 121 and the required squeezing force. For example, the pressure-applying part 132 can be a pressure protrusion extending outward from the circumference of the rotating part 131.

[0065] Based on the above-described structure of the control member 13, the first reset member 14 may include a coil spring, which is coaxially disposed with and connected to the rotating part 131. The coil spring can directly provide an elastic force to the rotating part 131 to reset its rotation. Besides this, the first reset member 14 may also have other structures and layouts, which will be further described in subsequent embodiments.

[0066] When unlocking is required, the user can apply external force to the control member 13 to rotate the rotating part 131, which then rotates towards the unlock position. As the rotating part 131 rotates, the connected pressure part 132 also rotates synchronously. During this rotation, the pressure part 132 gradually disengages from the pressure-bearing end 1212 of the claw part 121, and the pressure exerted on the pressure-bearing end 1212 of the claw part 121 gradually decreases until it disappears, thereby causing the claw part 121 to gradually release its grip on the connecting member 2, thus unlocking. When locking is required, the user can release the control member 13, and under the elastic force of the first reset member 14, the rotating part 131 rotates towards the locked position. As the rotating part 131 rotates, the pressure-applying part 132 gradually approaches the pressure-receiving end 1212 of the claw part 121. When the rotating part 131 rotates to a specific angle, that is, when it reaches the locking position, the pressure-applying part 132 accurately contacts the pressure-receiving end 1212 of the claw part 121 and begins to apply pressure, thereby causing the claw part 121 to clamp the connector 2.

[0067] The overall structure of the control component 13 is compact and reasonable. The connection between the rotating part 131 and the pressure-applying part 132 is simple and effective, reducing unnecessary parts and complex connection structures. Furthermore, the cooperative working mechanism of the rotating part 131 and the pressure-applying part 132 ensures that, in the locked state, the pressure-applying part 132 can stably and accurately apply compressive force to the pressure end 1212 of the claw part 121.

[0068] In some embodiments, refer to Figures 3 to 6 The control component 13 also includes a control lever 133, which is located on the periphery of the rotating part 131 and is connected to or integrally formed with the rotating part 131. The control lever 133 is used to drive the rotating part 131 to rotate when subjected to external force.

[0069] The control lever 133 is tightly connected to the rotating part 131, and can be either connected or integrally formed. Structurally, the control lever 133 extends outward from the periphery of the rotating part 131. This unique structural design allows the user to easily rotate the rotating part 131 by directly applying external force to the control lever 133. The length and shape of the control lever 133 can be optimized according to actual operational needs.

[0070] In some embodiments, refer to Figure 2 and Figure 3 The connecting module 11 has a first half shell 111 and a second half shell 112 that are connected to each other, and the second half shell 112 and the first half shell 111 enclose a receiving cavity.

[0071] Both claw portions 121 are rotatably connected to the first half-shell 111, and the pressure-receiving end 1212 of the claw portion 121 is located inside the receiving cavity, while the holding end 1211 of the claw portion 121 extends out of the receiving cavity.

[0072] The rotating part 131 is located inside the receiving cavity and is rotatably connected to at least one of the first half-shell 111 and the second half-shell 112; the pressure applying part 132 is located inside the receiving cavity.

[0073] One end of the control lever 133 is located inside the receiving cavity, and the other end of the control lever 133 extends out from the first half-shell and / or the second half-shell.

[0074] Specifically, the connecting module 11 consists of a first half-shell 111 and a second half-shell 112, which are connected by a detachable connection method, such as common snap-fit ​​connections, bolt connections, or magnetic connections. Taking a snap-fit ​​connection as an example, the first half-shell 111 has an inwardly protruding snap-fit ​​structure on its edge, and the second half-shell 112 has a corresponding slot to accommodate the snap-fit. By precisely inserting the snap-fit ​​into the slot, a tight connection is achieved between the two. Disassembly only requires applying appropriate external force to disengage the snap-fit ​​from the slot. This detachable connection method facilitates assembly and debugging during the manufacturing process. Furthermore, during later maintenance, the connecting module 11 can be easily opened to inspect, repair, or replace internal components. Of course, this is only an example and not a limitation; other detachable connection methods, such as screw connections, can also be used.

[0075] When the first half-shell 111 and the second half-shell 112 are connected, they cleverly enclose a closed receiving cavity. The size and shape of the receiving cavity are precisely designed to accommodate the installation and operation of the internal components. For example, the length, width, and height of the receiving cavity are customized according to the dimensions of the pressure-receiving end 1212, the rotating part 131, and the pressure-applying part 132 of the claw part 121, ensuring that each component has sufficient room to move within the cavity, while preventing the components from shaking due to excessive space. The receiving cavity not only provides physical protection for the internal components, preventing them from being impacted by the external environment, dust, or moisture, but also plays a role in positioning and supporting the components, ensuring their relative positional accuracy during operation.

[0076] Both jaw portions 121 are rotatably connected to the first half-shell 111. Specifically, this can be achieved by setting a special mounting shaft on the first half-shell 111, with corresponding matching holes on the jaw portions 121, which are then fitted onto the mounting shaft to form a rotating pair. A high-precision clearance fit is used between the rotating shaft and the holes, ensuring both the flexibility of the jaw portions 121's rotation and effectively controlling any wobbling during rotation. The pressure-receiving end 1212 of the jaw portion 121 is located within the receiving cavity. This layout allows the pressure-receiving end 1212 to directly receive the force from the control component 130, while the clamping end 1211 extends out of the receiving cavity, facilitating the clamping operation of the connector 2.

[0077] The rotating part 131, as the core rotating component of the control element 13, is installed in the receiving cavity and is rotatably connected to at least one of the first half-shell 111 and the second half-shell 112. If rotatably connected to the first half-shell 111, a support shaft may be provided on the first half-shell 111, and the rotating part 131 is sleeved on the support shaft to achieve a rotatable engagement with the first half-shell 111. If rotatably connected to the second half-shell 112, a corresponding connecting shaft will be provided on the second half-shell 112, and the rotating part 131 is sleeved on the connecting shaft to achieve a rotatable engagement with the second half-shell 112.

[0078] At least one of the first half-shell 111 and the second half-shell 112 is provided with an opening 11K. The size of the opening 11K is larger than the cross-sectional size of the control lever 133 and extends along the movement path of the control lever 133 to ensure that the control lever 133 can move freely along the opening 11K. When the first half-shell 111 is provided with an opening 11K, the opening 11K may be located at the edge of the first half-shell 111 that is used to mate with the second half-shell 112, so that the control lever 133 can pass through. When the second half-shell 112 is provided with an opening 11K, the opening 11K may be located at the edge of the second half-shell 112 that is used to mate with the first half-shell 111, so that the control lever 133 can pass through. When both the first half-shell 111 and the second half-shell 112 are provided with openings 11K, the openings 11K of the two are joined together to allow the control lever 133 to pass through. The control lever 133 protrudes from the opening 11K and is exposed outside the connection module 11 for easy operation by the user. By moving the control lever 133, the user can easily drive the rotating part 131 to rotate, thereby controlling the action of the pressure part 132.

[0079] In this embodiment, the double half-shell design of the connecting module 11 and the reasonable layout of each component in the receiving cavity make the structure of the entire quick-release assembly 1 more compact.

[0080] In some embodiments, refer to Figure 5 and Figure 6 The first half-shell 111 is provided with a receiving groove 111C, which extends around the rotation axis of the rotating part 131;

[0081] The control component 13 also includes a connecting part 134 extending into the receiving groove 111C. The connecting part 134 is located in the circumferential direction of the rotating part 131 and is movably disposed with the rotating part 131. The connecting part 134 can be directly connected to the rotating part 131, or it can be connected to the rotating part 131 by connecting to the control lever 133. When the rotating part 131 rotates, it will drive the connecting part 134 to rotate accordingly.

[0082] The first reset member 14 includes a spring, which is housed in a receiving groove 111C. One end of the spring is connected to the groove wall at one end of the receiving groove 111C, and the other end of the spring is connected to the connecting part 134.

[0083] Specifically, taking a tension spring as an example, when unlocking is required, the user applies an external force to the control lever 133. The control lever 133 drives the rotating part 131 to rotate around its rotation axis in the first direction until the pressure part 132 disengages from the pressure end 1212 of the claw part 121. At the same time, the connecting part 134 rotates with the rotating part 131 to move in the receiving groove 111C in the first direction, thereby stretching the spring located in the receiving groove 111C, so that the spring accumulates elastic potential energy.

[0084] When unlocking is required, the user can release the control lever 133, the tension spring releases its elastic potential energy, and the connecting part 134 moves in the receiving groove 111C in a second direction opposite to the first direction under the action of the elastic force of the tension spring, thereby driving the rotating part 131 to rotate around its rotation axis in the second direction until the pressure part 132 contacts the pressure end 1212 of the claw part 121 and squeezes it.

[0085] In addition to the tension springs illustrated above, compression springs can also be used, depending on actual needs. This embodiment does not impose any restrictions on this.

[0086] In this embodiment, the arrangement of the receiving groove 111C extending around the rotation axis of the rotating part 131, and the ingenious connection between the connecting part 134 and the spring, the rotating part 131, and / or the control lever 133, make the structure of the entire quick-release assembly 1 more compact. Furthermore, by rationally arranging the spring and the connecting part 134 within the receiving groove 111C, the internal space of the first half-shell 111 is fully utilized. This efficient space utilization not only improves the compactness of the structure but also reduces the risk of interference between components, making the internal structure of the entire quick-release assembly 1 clearer and more rational, facilitating manufacturing, installation, commissioning, and subsequent maintenance and repair.

[0087] Reference Figure 5 and Figure 6 Optionally, the number of receiving slots 111C is set to two, and the two receiving slots 111C are arranged opposite to each other;

[0088] The number of springs is set to two, and each spring is housed in a receiving slot 111C;

[0089] The number of connecting parts 134 is set to two. One of the two connecting parts 134 is connected to the rotating part 131 and extends into a receiving groove 111C to connect with the spring inside. The other is connected to the control lever 133 and extends into another receiving groove 111C to connect with the spring inside.

[0090] By incorporating two opposing receiving slots 111C, two springs, and two connecting parts 134, precise bidirectional control of the reset process of the rotating part 131 and the control lever 133 can be achieved. The elastic force of the two springs can accurately push the rotating part 131 and the control lever 133 back to their initial positions from two opposing directions, greatly improving the accuracy and consistency of reset compared to a single spring design. Furthermore, even if one spring experiences a certain degree of performance degradation during long-term use, the basic reset function can still be guaranteed due to the normal operation of the other spring. This redundant design improves the fault tolerance and service life of the quick-release assembly 1, reducing maintenance and replacement costs caused by component failure.

[0091] In some embodiments, refer to Figures 4 to 6 The rotating part 131 is provided with a mounting hole 131K, a limiting member 10, and a second resetting member 15. The mounting hole 131K is located on the periphery of the rotation axis of the rotating part 131. The limiting member 10 is slidably disposed in the mounting hole 131K and can extend or retract from the mounting hole 131K. The second resetting member 15 is disposed in the mounting hole 131K and is located between the limiting member 10 and the bottom wall of the mounting hole 131K. The second resetting member 15 acts on the limiting member 10 and is used to apply an elastic force to the limiting member 10 to reset it.

[0092] The first half-shell 111 is provided with a limiting hole 111K, and a pusher 20 is provided in the limiting hole 111K for sliding cooperation with it. The pusher 20 can extend or retract from one end of the limiting hole 111K.

[0093] The limiting hole 111K is located on the rotation path of the limiting member 10. The limiting member 10 can extend into the limiting hole 111K from one end opening under the elastic force of the second reset member 15 to form a stop limit on the rotating part 131. The pushing member 20 can push the limiting member 10 out of the limiting hole 111K by retracting into the limiting hole 111K to cancel the stop limit on the rotating part 131.

[0094] In this embodiment, the rotating part 131, through the cooperation of the limiting member 10 and the upper limit hole 111K of the first half-shell 111, can achieve precise positioning at a specific angle. For example, Figure 4 As shown, a second reset member 15 can be provided within the limiting hole 111K. One end of the second reset member 15 is connected to or abuts against the inner wall of the mounting hole 131K, and the other end of the second reset member 15 is connected to or abuts against the limiting member 10. The elastic force provided by the second reset member 15 to the limiting member 10 enables the limiting member 10 to extend outward from the mounting hole 131K and reset. Optionally, the limiting member 10 has a recessed hole, and the second reset member 15 extends into the recessed hole and abuts against the bottom wall of the recessed hole to achieve abutment with the limiting member 10. The second reset member 15 can be a compression spring.

[0095] The stop and limit process includes:

[0096] Initial state: When the rotating part 131 is in a free rotation state, the limiting member 10, under the action of the second reset member 15, protrudes from the mounting hole 131K from the surface of the rotating part 131 to abut against the inner wall of the first half shell 111, and waits to enter the limiting hole 111K to achieve limiting.

[0097] Rotation and Limit Trigger: When the rotating part 131 starts to rotate, as the rotation progresses, the limiting member 10 gradually approaches the limiting hole 111K. When the rotating part 131 rotates to a specific angle, the head of the limiting member 10 is exactly aligned with the limiting hole 111K. Under the elastic force of the second reset member 15, the limiting member 10 is smoothly inserted into the limiting hole 111K. Due to the high-precision fit between the limiting member 10 and the limiting hole 111K, the limiting member 10 forms a stop limit on the rotating part 131 after insertion, preventing the rotating part 131 from continuing to rotate and ensuring that the rotating part 131 stays at the set position.

[0098] Stable limiting state: In the limiting state, the limiting member 10 is tightly engaged with the limiting hole 111K, and the second elastic member continuously applies elastic force to the limiting member 10 to ensure that the limiting member 10 is securely locked in the limiting hole 111K.

[0099] The process of canceling the stop limit includes:

[0100] Operation trigger: When it is necessary to release the stop limit on the rotating part 131, an external force can be applied to the pusher 20. As the external force is applied, the pusher 20 retracts into the limiting hole 111K and moves towards the position of the limiting member 10. When the pusher 20 contacts the limiting member 10, the external force is continued to be applied, and the pusher 20 pushes the limiting member 10 out of the limiting hole 111K.

[0101] Resumption of free rotation: After the limiting member 10 is pushed out of the limiting hole 111K, it retracts into the mounting hole 131K. At this time, the rotating part 131 is released from the limiting constraint and returns to a free state, and can then continue to be operated to perform corresponding actions.

[0102] Optionally, the wall of the limiting hole 111K is constructed with a limiting step, which is used to limit the movement of the pusher 20 and prevent the pusher 20 from sliding out of the limiting hole 111K.

[0103] The specific angle at which the rotating part 131 achieves its positioning can be the angle corresponding to the quick-release assembly 1 being in the unlocked state. That is, when the limiting member 10 is inserted into the limiting hole 111K to form a limiting fit, so that the position of the rotating part 131 relative to the connecting module 11 is fixed and cannot be rotated, the quick-release assembly 1 remains in the unlocked state. When the limiting member 10 is pushed out of the limiting hole 111K by the pushing member 20 to cancel the limiting fit, so that the rotating part 131 can rotate relative to the connecting module 11, the quick-release assembly 1 can switch from the unlocked state to other states such as the locked state.

[0104] In practical applications, the quick-release assembly 1 is in an unlocked state due to the limiting engagement between the limiting member 10 and the limiting hole 111K. Correspondingly, the operating member 13 does not compress the two claw portions 121, and thus, the two claw portions 121 are in a relaxed state. Therefore, when assembling the quick-release assembly 1 and the connecting member 2, the quick-release assembly 1 can be pressed directly toward the connecting member 2, and the connecting member 2 can easily push open the two claw portions 121 and be inserted between them. After the connecting member 2 is inserted into place, the connecting member 2 will press the pushing member 20 to retract it into the limiting hole 111K. The pushing member 20 will push the limiting member 10 out of the limiting hole 111K to cancel the stop limiting of the rotating part 131. When the stop limit of the rotating part 131 is removed, under the elastic force of the first reset member 14, the rotating part 131 rotates toward the locked position, so that the pressure part 132 squeezes the pressure end 1212 of the claw part 121, the claw part 121 clamps the connector 2, and the quick release assembly 1 automatically switches from the unlocked state to the locked state. It is simple to operate, convenient to use, and easy to use.

[0105] In addition, after the quick-release component 1 and the connector 2 are disassembled, the user can manually operate the control lever 133 to drive the rotating part 131 to rotate, so that the limiting part 10 is inserted into the limiting hole 111K to form a limiting fit, that is, the quick-release component 1 is pre-switched to the unlocked state, so as to facilitate the next assembly operation.

[0106] In some embodiments, refer to Figure 5 and Figure 6 The rotating part 131 is provided with a shaft hole 131Z, and the inner wall of the second half shell 112 is provided with a connecting shaft 1121. The connecting shaft 1121 is inserted into the shaft hole 131Z so that the rotating part 131 and the second half shell 112 are rotatably connected.

[0107] The connecting shaft 1121 is provided with a connecting hole 1121K, which extends along the axial direction of the connecting shaft 1121 and penetrates the outer wall of the second half shell 112.

[0108] In this embodiment, to achieve a rotatable connection with the second half-shell 112, the rotating part 131 is provided with a shaft hole 131Z. The shaft hole 131Z is typically circular in shape to accommodate the connecting shaft 1121 that mates with it. The rotating part 131 rotatably engages with the connecting shaft 1121 of the second half-shell 112 through the shaft hole 131Z, thereby achieving a rotatable connection with the second half-shell 112 and enabling stable rotation. The second half-shell 112 is provided with a connecting hole 1121K at the location of the connecting shaft 1121. The function of the connecting hole 1121K is to connect an external photographic device, for example, it can be used to connect the main body of an accessory. The connecting hole 1121K can be a threaded hole, etc., and this embodiment does not limit this. By utilizing the structural position of the connecting shaft 1121 to set the connecting hole 1121K, no extra space is occupied, the structure is compact, and the design of the connecting hole 1121K also expands the function of the quick-release assembly 1.

[0109] In some embodiments, refer to Figure 3 and Figure 4 The connecting module 11 is provided with a magnetic attraction structure, which is used to generate a magnetic attraction force on the pressure end 1212 of the claw part 121. The direction of the magnetic attraction force is the same as the direction in which the control member 13 squeezes the pressure end 1212.

[0110] As an example, the claw portion 121 may be provided with a first magnetic attractor 30, which is located at the pressure end 1212 of the claw portion 121; the connecting module 11 may be provided with a second magnetic attractor 40, which is positioned opposite to the first magnetic attractor 30 and applies a magnetic attraction force to the first magnetic attractor 30.

[0111] In this configuration, one of the first magnetic attractor 30 and the second magnetic attractor 40 can be a magnetic block, and the other can be a magnetically attractable metal block, or both can be magnetic blocks, depending on the actual requirements. The pressure-receiving end 1212 of the claw portion 121 is provided with a groove adapted to the first magnetic attractor 30, and the first magnetic attractor 30 is housed in the groove. The magnetic attraction force generated by the second magnetic attractor 40 on the first magnetic attractor 30 is in the same direction as the compressive force applied by the control member 13 to the pressure-receiving end 1212.

[0112] In other words, the design of the first magnetic suction member 30 and the second magnetic suction member 40 works closely in coordination with the control member 13. Specifically, the combined effect of the magnetic attraction force and the squeezing force of the control member 13 was fully considered during the design process. Through mechanical analysis and simulation calculations, the magnitude and direction of the magnetic attraction force of the magnetic suction member were determined, so that it cooperates with the squeezing force applied by the control member 13 to the pressure end 1212 of the claw portion 121, jointly enhancing the clamping force of the claw portion 121. For example, in the locked state, the squeezing force of the control member 13 and the magnetic attraction force of the magnetic suction member act simultaneously on the pressure end 1212 of the claw portion 121, enabling the claw portion 121 to clamp the connector 2 more tightly and improve the stability of the connection.

[0115] In some embodiments, refer to Figure 1 and Figure 2 The connecting module 11 can slide relative to the connecting member 2 along the length direction of the connecting member 2;

[0116] The connector 2 is provided with multiple positioning grooves 2C, which are spaced apart along the length of the connector 2. The connecting module 11 is provided with positioning protrusions 11B, which are used to engage with the positioning grooves 2C to position the connecting module 11.

[0117] In this embodiment, the quick-release component 1 can slide relative to the connector 2 via the connecting module 11 to adjust its installation position on the connector 2. After moving to the pre-adjusted position, the connecting module 11 is positioned by the positioning protrusion 11B engaging with the positioning groove 2C. Then, the quick-release component 1 clamps the connector 2 to achieve the connection and assembly of the two. This helps improve the positional accuracy of the quick-release component 1 on the connector 2 and the connection stability between the quick-release component 1 and the connector 2. There can be two positioning protrusions 11B, which are spaced apart at opposite ends of the connecting module 11 along the sliding direction of the connecting module 11. The connecting module 11 is positioned by the engagement of the two positioning protrusions 11B with two of the multiple positioning grooves 2C.
