[0049] The embodiment of the present invention provides a quick release assembly 100 for photographic accessories, referring to Figure 1 and Figure 2 , the quick release assembly 100 comprises:

[0050] Connecting seat 110;

[0051] Two clamping arms 120 are respectively disposed on opposite sides of the connecting seat 110 and are movably connected to the connecting seat 110. The two clamping arms 120 and the connecting seat 110 are surrounded to form a fitting groove 10, and the fitting groove 10 is used to fit on the structural member 200;

[0052] The locking assembly 130 is disposed on the connecting seat 110 and acts on the two clamping arms 120;

[0053] The quick-release assembly 100 has a locked state and an unlocked state. In the locked state, the locking assembly 130 squeezes the two clamp arms 120 so that the two clamp arms 120 close together to clamp the structural component 200; in the unlocked state, the locking assembly 130 loosens the two clamp arms 120 so that the two clamp arms 120 can open back to back to loosen the structural component 200.

[0054] The quick release assembly 100 involved in this embodiment is applied to photographic equipment to achieve connection between components in the photographic equipment. The quick release assembly 100 can be connected to the structural member 200. In actual application, two components in the photographic equipment can be connected through the connection between the quick release assembly 100 and the structural member 200.

[0055] Specifically, take the two components in the photographic equipment as an example, namely the first component and the second component, wherein the first component is connected to the quick release assembly 100, and the connection form may include screw connection, snap connection, etc., which is not limited in this embodiment. For example, Figure 1 As shown, the connection seat 110 of the quick release assembly 100 is provided with a connection hole 1121K for connecting a first device, wherein the first device may be a functional device such as a fill light, a microphone, etc., including but not limited to these.

[0056] The structural member 200 involved may be the second device to be connected, that is, the first device is connected to the quick-release assembly 100, and the quick-release assembly 100 is connected to the structural member 200 (i.e., the second device), thereby realizing the connection between the two devices. Alternatively, the structural member 200 may also be connected to the second device as an intermediate member, and the connection form may include screw connection, snap connection, etc., that is, the first device is connected to the quick-release assembly 100, and the second device is connected to the structural member 200, and the quick-release assembly 100 is connected to the structural member 200, thereby realizing the connection between the two devices. The second device may be, for example, a photographic stand, including but not limited to this.

[0057] In the quick-release assembly 100, the connection seat 110 serves as a basic bearing component, providing a foundation for the installation and connection of other components. The clamp arm 120 cooperates with the connection seat 110 through a movable connection method, and can move within a certain range. The movable connection method can be a sliding connection, a rotating connection, etc., including but not limited to this. The movable connection method of the clamp arm 120 enables it to move relative to the connection seat 110 as needed to achieve an opening and closing action, so as to adapt to structural members 200 of different sizes and achieve clamping thereof. For example, the clamp arm 120 is rotatably connected to the connection seat 110, and the clamp arm 120 can rotate around the connection point to a certain angle to achieve opening and closing.

[0058] In addition, the locking assembly 130, as a key component for switching between the locked and unlocked states of the quick-release assembly 100, controls the motion state of the two clamp arms 120 by applying and releasing mechanical force. When the locking assembly 130 applies pressure, the two clamp arms 120 are closed toward each other by the pressure, and the structural component 200 sleeved in the sleeve groove 10 is tightly fixed by friction and clamping force; when the locking assembly 130 releases the pressure, the clamp arms 120 open back to back under their own elastic restoring force or external micro-force, thereby releasing the structural component 200.

[0059] The locking assembly 130 may include some mechanical transmission structures, such as cam transmission or lever transmission. Taking the cam transmission as an example, the rotation of the cam will change the position of the contact point between its profile and the clamp arm 120, and the change of the cam profile is used to push the clamp arm 120 to move. The lever transmission is based on the lever arm principle, which amplifies the force applied to one end of the lever and transmits it to the clamp arm 120 to achieve the movement of the clamp arm 120. The above is only exemplary and not restrictive. In addition, the locking assembly 130 can also be other structural forms.

[0060] When the locking assembly 130 applies pressure, the two clamp arms 120 rotate in opposite directions around the active connection point with the connecting seat 110 under the action of the external force according to the principle of mechanics. When the clamp arms 120 contact the structural member 200, according to the principle of friction, the clamp arms 120 generate positive pressure on the surface of the structural member 200, thereby generating friction. At the same time, the closing action of the clamp arms 120 will also generate a clamping force on the surface of the structural member 200. These two forces work together to tightly fix the structural member 200 located in the sleeve groove 10. When the locking assembly 130 releases the pressure, the clamp arms 120, under the action of their own elastic restoring force (if the clamp arms 120 are made of a material with a certain elasticity) or a small force applied from the outside (for example, the user manually gently pries the clamp arms 120 open), again according to the principle of mechanics, rotate back to back around the active connection point with the connecting seat 110, thereby loosening the structural member 200.

[0061] The specific process includes:

[0062] Locking process:

[0063] First, the photographic device to be connected is mounted on the structural member 200 through the mounting groove 10 of the quick release assembly 100, and then the locking assembly 130 is operated, and the locking assembly 130 begins to press the two clamping arms 120 to apply pressure, and the two clamping arms 120 gradually close to the middle under the pressure. As the two clamping arms 120 close toward each other, the space of the mounting groove 10 gradually decreases until the clamping arms 120 are in close contact with the structural member 200, and the structural member 200 is firmly clamped by friction and clamping force, completing the locking connection between the quick release assembly 100 and the structural member 200.

[0064] Unlocking process:

[0065] When the photographic device needs to be disassembled, the locking assembly 130 is operated in the reverse direction to release the squeezing of the two clamping arms 120. At this time, the two clamping arms 120 open backwards under their own automatic movement or a slight force applied from the outside (for example, the user manually opens the clamping arms 120). As the two clamping arms 120 open backwards, the space of the set slot 10 gradually increases, so that the clamping force between the quick release assembly 100 and the structural member 200 disappears. At this time, the quick release assembly 100 can be easily separated from the structural member 200, completing the unlocking process.

[0066] Based on the requirement of stable connection of components in photographic equipment, the quick release assembly 100 realizes stable clamping and quick disassembly of the structural component 200 through the coordinated work of the connection seat 110, the clamping arm 120 and the locking assembly 130. The clamping force of the two clamping arms 120 on the structural component 200 is controlled by the squeezing and loosening action of the locking assembly 130, thereby realizing the switching of the locking and unlocking states of the quick release assembly 100.

[0067] The quick-release assembly 100 of the present invention can ensure a stable connection between components of photographic equipment, ensuring that the components are not prone to shaking or falling off during the use of the photographic equipment, thereby ensuring shooting stability and image quality, improving the user experience, and thus meeting the user's requirements for the stability and reliability of photographic equipment.

[0068] In some embodiments, reference Figures 2 to 4 , both clamp arms 120 are rotatably connected to the connection seat 110 , one end of the clamp arm 120 is a clamping end 121 for clamping the structural member 200 , and the other end of the clamp arm 120 is a pressure-bearing end 122 ;

[0069] The locking assembly 130 includes:

[0070] The unlocking operation member 131 is movably connected to the connecting seat 110. The unlocking operation member 131 is used to movably switch to the locking position to squeeze the pressure-receiving end 122, so that the clamping arm 120 rotates to drive the clamping end 121 to clamp the structural member 200, or movably switch to the unlocking position to release the pressure-receiving end 122, so that the clamping arm 120 can rotate to drive the clamping end 121 to release the structural member 200;

[0071] The first elastic member 132 acts on the unlocking operating member 131 . The first elastic member 132 is used to provide an elastic force to the unlocking operating member 131 to reset the unlocking operating member 131 to the locking position.

[0072] In this embodiment, both clamp arms 120 are connected to the connecting seat 110 in a rotational manner, and this design provides a basis for the flexible opening and closing of the clamp arms 120. One end of the clamp arm 120 is designed as a clamping end 121 specifically used to clamp the structural member 200. The clamping end 121 is roughly hook-shaped, and the other end is a pressure-bearing end 122. This clear functional division enables the clamp arm 120 to efficiently clamp and release the structural member 200 during the entire working process of the quick-release assembly 100. The locking assembly 130, as the core control component of the quick-release assembly 100, has an ingenious structural design and is mainly composed of an unlocking operating member 131 and a first elastic member 132. The unlocking operating member 131 is movably connected to the connecting seat 110, and the movable connection includes a rotating connection, a sliding connection, etc., but is not limited to this. This movable connection mode enables the unlocking operating member 131 to switch positions on the connecting seat 110. Specifically, the unlocking operating member 131 has the function of switching to the locking position through movement. When in the locking position, it can squeeze the compressed end 122 of the clamp arm 120, thereby applying a squeezing force. At the same time, the unlocking operating member 131 can also switch to the unlocking position through movement, at which time the compressed end 122 of the clamp arm 120 will be released, thereby canceling the squeezing force. The first elastic member 132 plays a vital role in the locking assembly 130. It acts on the unlocking operating member 131, and its main function is to provide the unlocking operating member 131 with an elastic force to reset its movement toward the locking position. In addition, the existence of this elastic force ensures that the unlocking operating member 131 can automatically remain in the locking position when there is no external force intervention, thereby ensuring that the clamp arm 120 can stably clamp the structural member 200. Among them, the first elastic member 132 can be a tension spring, a compression spring, a coil spring, etc., which can be set according to actual needs.

[0073] Principle of the locking process: When the quick-release assembly 100 needs to be connected and locked with the structural member 200, the structural member 200 is first placed in the fitting groove 10 formed by the two clamping arms 120 and the connecting seat 110. Subsequently, the unlocking operating member 131 is acted upon by a force (such as the elastic force of the first elastic member 132) and moves from the initial position to the locking position. As the unlocking operating member 131 switches to the locking position, it contacts the compressed end 122 of the clamping arm 120 and begins to apply a squeezing force. According to the lever principle, the clamping arm 120 uses its rotational connection point with the connecting seat 110 as a fulcrum. After the compressed end 122 is subjected to a squeezing force, the clamping end 121 rotates toward each other around the fulcrum. In this process, the clamping ends 121 of the two clamping arms 120 gradually approach each other and finally tightly clamp the structural member 200. At the same time, the first elastic member 132 undergoes elastic deformation and releases elastic potential energy during the movement of the unlocking operating member 131 to the locking position. When the unlocking operating member 131 reaches the locking position, the first elastic member 132 continuously applies an elastic force toward the locking position to the unlocking operating member 131, ensuring that the unlocking operating member 131 always maintains a squeezing force on the compressed end 122 of the clamping arm 120, thereby maintaining a stable clamping state of the clamping arm 120 on the structural member 200.

[0074] When it is necessary to disassemble the quick-release assembly 100 and the structural member 200, that is, to release the clamping of the clamping arm 120 on the structural member 200, an external force in the opposite direction to the locking process is applied to the unlocking operating member 131, so that the unlocking operating member 131 overcomes the elastic force of the first elastic member 132 and moves from the locking position to the unlocking position. As the unlocking operating member 131 moves, its squeezing force on the compressed end 122 of the clamping arm 120 gradually decreases until it disappears. At this time, under the action of its own gravity (if the gravity of the clamping arm 120 is sufficient to overcome the rotation resistance) or other external forces, the clamping end 121 rotates in the opposite direction around the fulcrum with the rotation connection point with the connecting seat 110 as the fulcrum, thereby gradually loosening the clamping of the structural member 200. In this process, the first elastic member 132 undergoes elastic deformation and accumulates elastic potential energy.

[0075] The locking assembly 130, through the synergistic effect of the unlocking operating member 131 and the first elastic member 132, can continuously and stably apply a squeezing force to the pressure-bearing end 122 of the clamp arm 120 in the locked state, ensuring that the clamp arm 120 firmly clamps the structural member 200, so that the connection between the components is more stable during the use of the photographic equipment. In addition, the design of the unlocking operating member 131 allows the user to switch the locked and unlocked states of the quick-release assembly 100 through simple operations (such as toggling, pressing, etc.). At the same time, the automatic reset function of the first elastic member 132 reduces the extra steps of the user during the operation process. The user does not need to manually reset the unlocking operating member 131 to the locked position, and the operation is smoother and more efficient.

[0076] In some embodiments, reference Figures 3 to 6 , the unlocking operating member 131 includes:

[0077] The rotating part 1311 is rotatably connected to the connecting seat 110;

[0078] The lever portion 1312 is connected to or integrally formed with the rotating portion 1311. The lever portion 1312 extends outward from the circumference of the rotating portion 1311. When the lever portion 1312 is acted upon by an external force, it drives the rotating portion 1311 to rotate.

[0079] The pressure-applying portion 1313 is connected to or integrally formed with the rotating portion 1311 . The pressure-applying portion 1313 is used to switch positions with the rotation of the rotating portion 1311 to squeeze or release the pressed end 122 .

[0080] Specifically, the rotating portion 1311, as the core rotating part of the unlocking operating member 131, is connected to the connecting seat 110 by rotation, which can be realized by a specific rotating pair, such as a common pin connection or a bearing connection, to ensure that the rotating portion 1311 can rotate flexibly and stably on the connecting seat 110. The design of the rotating portion 1311 provides a rotation basis for the entire unlocking operating member 131 to perform actions, so that other components can realize corresponding functions as it rotates. Among them, the rotating portion 1311 can be located between the pressure-bearing ends 122 of the two clamping arms 120.

[0081] The lever portion 1312 is closely connected to the rotating portion 1311, and can be connected or integrally formed. From the perspective of structural layout, the lever portion 1312 is extended outward from the peripheral side of the rotating portion 1311. This unique structural design allows the user to easily drive the rotating portion 1311 to rotate by directly applying external force to the lever portion 1312. The length and shape of the lever portion 1312 can be optimized according to actual operation requirements. For example, in order to facilitate the user to hold and operate, the lever portion 1312 can be designed to have a rod body shape with a certain length and a non-slip surface.

[0082] The pressure-applying portion 1313 is also connected to or integrally formed with the rotating portion 1311. The main function of the pressure-applying portion 1313 is to switch positions as the rotating portion 1311 rotates, thereby achieving the squeezing or releasing operation on the pressure-receiving end 122 of the clamp arm 120. The shape and size of the pressure-applying portion 1313 are specifically designed according to the structure of the pressure-receiving end 122 of the clamp arm 120 and the required squeezing force. For example, the pressure-applying portion 1313 can be a pressure-applying protrusion protruding outward from the circumference of the rotating portion 1311.

[0083] Based on the above structural composition of the unlocking operating member 131, the first elastic member 132 may include a coil spring, which is coaxially arranged and connected to the rotating portion 1311, and the coil spring may directly provide elastic force to the rotating portion 1311 to rotate and reset it. In addition, the first elastic member 132 may also have other structures and layout forms, which will be further described in the subsequent embodiments.

[0084] When unlocking is required, the user can apply an external force to the lever portion 1312, and the lever portion 1312 drives the rotating portion 1311 to rotate, and the rotating portion 1311 rotates toward the unlocking position. As the rotating portion 1311 rotates, the pressure-applying portion 1313 connected thereto also rotates synchronously. During the rotation process, the pressure-applying portion 1313 gradually separates from the pressure-receiving end 122 of the clamping arm 120, and its squeezing force on the pressure-receiving end 122 of the clamping arm 120 gradually decreases until it disappears, thereby causing the clamping arm 120 to gradually loosen its grip on the structural member 200, thereby achieving unlocking. When locking is required, the user can loosen the lever portion 1312, and under the elastic force of the first elastic member 132, the rotating portion 1311 rotates toward the locking position. As the rotating portion 1311 rotates, the pressure-applying portion 1313 gradually approaches the pressure-receiving end 122 of the clamping arm 120. When the rotating portion 1311 rotates to a specific angle, that is, reaches the locking position, the pressure-applying portion 1313 accurately contacts the pressure-receiving end 122 of the clamping arm 120 and begins to apply extrusion force, thereby enabling the clamping arm 120 to clamp the structural component 200.

[0085] The overall structure design of the unlocking operating member 131 is compact and reasonable, and the connection between the rotating part 1311, the lever part 1312 and the pressure part 1313 is simple and effective, reducing unnecessary parts and complex connection structures. In addition, the cooperative working mechanism of the rotating part 1311, the lever part 1312 and the pressure part 1313 ensures that in the locked state, the pressure part 1313 can stably and accurately apply a squeezing force to the pressure end 122 of the clamp arm 120.

[0086] In some embodiments, reference Figure 2 and Figure 3 The connecting seat 110 includes a first half shell 111 and a second half shell 112 detachably connected to the first half shell 111, and the second half shell 112 and the first half shell 111 are enclosed to form a receiving cavity;

[0087] The two clamp arms 120 are both rotatably connected to the first half shell 111, and the pressure-bearing end 122 of the clamp arm 120 is located in the accommodating cavity, and the clamping end 121 of the clamp arm 120 extends out of the accommodating cavity;

[0088] The rotating portion 1311 is located in the accommodating cavity and is rotatably connected to at least one of the first half shell 111 and the second half shell 112. The pressure-applying portion 1313 is located in the accommodating cavity. At least one of the first half shell 111 and the second half shell 112 is provided with an avoidance opening 110K. The lever portion 1312 passes through the avoidance opening 110K to be exposed outside the connecting seat 110.

[0089] Specifically, the connecting seat 110 is composed of a first half shell 111 and a second half shell 112, and the two are connected in a detachable manner, such as a common snap connection, a bolt connection or a magnetic connection. Taking the snap connection as an example, the edge of the first half shell 111 is provided with an inwardly protruding snap structure, and the corresponding position of the second half shell 112 is provided with a slot for accommodating the snap. The snap is accurately inserted into the slot to achieve a tight connection between the two, and when disassembling, it is only necessary to apply appropriate external force to make the snap out of the slot. This detachable connection method is convenient for assembly and debugging during the production process. At the same time, during later maintenance, the connecting seat 110 can be easily opened to inspect, repair or replace the internal components. Of course, this is only exemplary and not restrictive, and detachable connection methods such as screw connection can also be adopted.

[0090] When the first half shell 111 and the second half shell 112 are connected, the two are cleverly enclosed to form a closed accommodating cavity. The size and shape of the accommodating cavity are precisely designed to adapt to the installation and operation of the internal components. For example, the length, width and height of the accommodating cavity are customized according to the size of the pressure-bearing end 122, the rotating part 1311 and the pressure-applying part 1313 of the clamping arm 120 to ensure that the components have enough space to move in the cavity, while the components will not shake due to excessive space. The accommodating cavity not only provides physical protection for the internal components to prevent them from being hit, dust or water vapor erosion by the external environment, but also plays a role in positioning and supporting the components to ensure their relative position accuracy during operation.

[0091] Both clamp arms 120 are rotatably connected with the first half shell 111, which can be achieved by setting a special mounting shaft on the first half shell 111, and setting a matching hole at the corresponding position on the clamp arm 120, and sleeved on the mounting shaft through the hole to form a rotating pair. The high-precision clearance fit between the rotating shaft and the hole can not only ensure the flexibility of the clamp arm 120 in rotation, but also effectively control the shaking during the rotation process. The pressure-bearing end 122 of the clamp arm 120 is located in the accommodating cavity. Such a layout enables the pressure-bearing end 122 to directly receive the force from the locking assembly 130, while the clamping end 121 extends out of the accommodating cavity, which is convenient for clamping the structural member 200.

[0092] The rotating portion 1311 is the core rotating component of the unlocking operating member 131, installed in the accommodating cavity, and is rotatably connected to at least one of the first half shell 111 and the second half shell 112. If it is rotatably connected to the first half shell 111, a support shaft may be provided on the first half shell 111, and the rotating portion 1311 is sleeved on the support shaft to achieve rotational cooperation with the first half shell 111. If it is rotatably connected to the second half shell 112, a corresponding connecting shaft will be provided on the second half shell 112, and the rotating portion 1311 is sleeved on the connecting shaft to achieve rotational cooperation with the second half shell 112.

[0093] At least one of the first half shell 111 and the second half shell 112 is provided with an escape opening 110K, the size of the escape opening 110K is larger than the cross-sectional size of the lever portion 1312 and is extended along the movable path of the lever portion 1312 to ensure that the lever portion 1312 can move freely along the opening. When the first half shell 111 is provided with an escape opening 110K, the escape opening 110K may be located at the edge of the first half shell 111 for docking with the second half shell 112, so as to allow the lever portion 1312 to pass through; when the second half shell 112 is provided with an escape opening 110K, the escape opening 110K may be located at the edge of the second half shell 112 for docking with the first half shell 111, so as to allow the lever portion 1312 to pass through; when both the first half shell 111 and the second half shell 112 are provided with an escape opening 110K, the escape openings 110K of the two are combined to allow the lever portion 1312 to pass through. The lever portion 1312 passes through the avoidance opening 110K to be exposed outside the connection base 110 , which is convenient for the user to directly operate. The user can easily drive the rotating portion 1311 to rotate by shifting the lever portion 1312 , thereby controlling the movement of the pressure applying portion 1313 .

[0094] In this embodiment, the double half-shell design of the connecting seat 110 and the reasonable layout of various components in the accommodating cavity make the structure of the entire quick-release assembly 100 more compact.

[0095] In some embodiments, reference Figure 5 and Figure 6 The first half shell 111 is provided with a receiving groove 111C, and the receiving groove 111C is extended around the rotation axis of the rotating part 1311;

[0096] The unlocking operation member 131 further includes a connecting portion 1314 extending into the receiving groove 111C, the connecting portion 1314 is located in the circumferential direction of the rotating portion 1311 and is arranged to move with the rotating portion 1311; wherein the connecting portion 1314 may be directly connected to the rotating portion 1311, or may be connected to the rotating portion 1311 by connecting to the lever portion 1312, and when the rotating portion 1311 rotates, the connecting portion 1314 is driven to rotate accordingly;

[0097] The first elastic member 132 includes a spring, which is accommodated in the receiving groove 111C. One end of the spring is connected to a groove wall at one end of the receiving groove 111C, and the other end of the spring is connected to the connecting portion 1314 .

[0098] Specifically, taking the spring as a tension spring as an example, when unlocking is required, the user applies an external force to the lever portion 1312, and the lever portion 1312 drives the rotating portion 1311 to rotate along the first direction around its rotation axis until the pressure-applying portion 1313 is out of contact with the pressure-receiving end 122 of the clamp arm 120. At the same time, the connecting portion 1314 rotates with the rotating portion 1311 to move along the first direction in the receiving groove 111C, thereby lengthening the spring in the receiving groove 111C, so that the spring accumulates elastic potential energy.

[0099] When unlocking is required, the user can loosen the lever portion 1312, the tension spring releases its elastic potential energy, and the connecting portion 1314 moves in the accommodating groove 111C along a second direction opposite to the first direction under the elastic force of the tension spring, thereby driving the rotating portion 1311 to rotate along the second direction around its rotation axis until the pressure-applying portion 1313 contacts and squeezes the pressure end 122 of the clamping arm 120.

[0100] In addition to the tension springs described above as examples, the springs may also be compression springs, which can be selected based on actual needs, and this embodiment does not impose any limitation on this.

[0101] In this embodiment, the way in which the receiving groove 111C is extended around the rotation axis of the rotating part 1311, and the ingenious connection between the connecting part 1314 and the spring, the rotating part 1311 and / or the lever part 1312, makes the structure of the entire quick-release assembly 100 more compact. In addition, by rationally arranging the spring and the connecting part 1314 in the receiving groove 111C, the space inside the first half shell 111 is fully utilized. This efficient space utilization method not only improves the compactness of the structure, but also reduces the risk of mutual interference between components, making the internal structure of the entire quick-release assembly 100 clearer and more reasonable, and facilitating production, installation and commissioning, as well as later maintenance and repair.

[0102] In some embodiments, reference Figure 5 and Figure 6 , the number of the receiving grooves 111C is set to two, and the two receiving grooves 111C are arranged opposite to each other;

[0103] The number of springs is correspondingly set to two, and each spring is accommodated in a receiving groove 111C;

[0104] The number of the connecting parts 1314 is set to two, one of which is connected to the rotating part 1311 and extends into an accommodating groove 111C to connect with the spring therein, and the other is connected to the lever part 1312 and extends into another accommodating groove 111C to connect with the spring therein.

[0105] In this embodiment, by providing two opposite receiving grooves 111C, two springs and two connecting parts 1314, accurate two-way control of the resetting process of the rotating part 1311 and the lever part 1312 can be achieved. The elastic force of the two springs can accurately push the rotating part 1311 and the lever part 1312 back to the initial state from two relative directions, which greatly improves the accuracy and consistency of the resetting compared to the design of a single spring. In addition, during long-term use, even if one of the springs has a certain degree of performance degradation, the basic resetting 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 100 and reduces the maintenance and replacement costs caused by component failures.

[0106] In some embodiments, reference Figure 5 and Figure 6 The rotating part 1311 is configured with an axial hole 1311Z, and the inner wall of the second half shell 112 is provided with a connecting shaft 1121, and the connecting shaft 1121 is inserted into the axial hole 1311Z so that the rotating part 1311 is rotatably connected with the second half shell 112;

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

[0108] In this embodiment, in order to realize the rotational connection with the second half shell 112, the rotating part 1311 is provided with an axial hole 1311Z, and the shape of the axial hole 1311Z is generally circular to adapt to the connecting shaft 1121 matched therewith. The rotating part 1311 is rotationally matched with the connecting shaft 1121 of the second half shell 112 through the axial hole 1311Z to be rotationally connected with the second half shell 112 and can rotate stably. The second half shell 112 is provided with a connecting hole 1121K at the position 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 accessory body. Among them, the connecting hole 1121K can be a threaded hole, etc., which is not limited in this embodiment. Among them, by utilizing the structural position of the connecting shaft 1121 to set the connecting hole 1121K, no additional space is occupied, the structure is compact, and the design of the connecting hole 1121K also expands the function of the quick release assembly 100.

[0109] In some embodiments, reference Figures 4 to 6The rotating part 1311 is provided with a mounting hole 1311K and a stopper 20, the mounting hole 1311K is located on the peripheral side of the rotating axis of the rotating part 1311, and the stopper 20 is slidably disposed in the mounting hole 1311K and can be elastically extended or retracted from the mounting hole 1311K;

[0110] The first half shell 111 is provided with a limiting hole 111K through which a pusher 30 slidably matched is provided. The pusher 30 can extend from or retract from one end of the limiting hole 111K.

[0111] Among them, the limiting hole 111K is located on the rotation path of the limiting member 20, and the limiting member 20 can extend into the limiting hole 111K from an end hole of the limiting hole 111K to form a stop limit for the rotating part 1311; the pushing member 30 can push the limiting member 20 out of the limiting hole 111K by retracting into the limiting hole 111K to cancel the stop limit for the rotating part 1311.

[0112] In this embodiment, the rotating part 1311 can be precisely positioned at a specific angle through the cooperation between the stopper 20 and the upper limit hole 111K of the first half shell 111. Figure 4 As shown, a second elastic member 133 may be disposed in the limiting hole 111K, one end of the second elastic member 133 is connected or abutted with the inner wall of the mounting hole 1311K, and the other end of the second elastic member 133 is connected or abutted with the limiting member 20, and the second elastic member 133 provides an elastic force to the limiting member 20 to extend outward from the mounting hole 1311K and reset. Optionally, the limiting member 20 is provided with a concave hole, and the second elastic member 133 extends into the concave hole and abuts with the bottom wall of the concave hole to achieve abutment with the limiting member 20. The second elastic member 133 may be a compression spring.

[0113] The stop limit process includes:

[0114] Initial state: when the rotating part 1311 is in a free rotation state, the limiting member 20, under the action of the elastic element (such as the second elastic member 133), protrudes from the mounting hole 1311K to the surface of the rotating part 1311 to abut against the inner wall of the first half shell 111, and waits to enter the limiting hole 111K to achieve limiting;

[0115] Rotation and limit triggering: When the rotating part 1311 starts to rotate, as the rotation proceeds, the limit member 20 gradually approaches the limit hole 111K. When the rotating part 1311 rotates to a specific angle, the head of the limit member 20 is aligned with the limit hole 111K, and under the action of the elastic element (such as the second elastic member 133), the limit member 20 is smoothly inserted into the limit hole 111K. Due to the high-precision fit between the limit member 20 and the limit hole 111K, the limit member 20 forms a stop limit for the rotating part 1311 after insertion, preventing the rotating part 1311 from continuing to rotate, and ensuring that the rotating part 1311 stays at the set position.

[0116] Stable limiting state: In the limiting state, the limiting member 20 is tightly matched with the limiting hole 111K, and the second elastic member continuously applies elastic force to the limiting member 20 to ensure that the limiting member 20 is firmly stuck in the limiting hole 111K.

[0117] The process of cancelling the stop limit includes:

[0118] Operation trigger: When the stop limit of the rotating part 1311 needs to be cancelled, an external force can be applied to the push member 30. As the external force is applied, the push member 30 retracts into the limit hole 111K and moves toward the position of the limit member 20. When the push member 30 contacts the limit member 20, the external force continues to be applied, and the push member 30 pushes the limit member 20 out of the limit hole 111K.

[0119] Restoration of free rotation: After the limiting member 20 is pushed out of the limiting hole 111K, it retracts into the mounting hole 1311K accordingly. At this time, the rotating part 1311 is released from the limiting constraint and restored to a free state, and can then continue to be operated to perform corresponding actions.

[0120] Optionally, a hole wall of the limiting hole 111K is structured with a limiting step, and the limiting step is used to limit the movement of the pushing member 30 to prevent the pushing member 30 from sliding out of the limiting hole 111K.

[0121] The specific angle at which the rotating part 1311 is positioned can be the angle corresponding to the quick release assembly 100 in the unlocked state, that is, when the limiting member 20 is inserted into the limiting hole 111K to form a limiting fit, so that the position of the rotating part 1311 relative to the connecting seat 110 is fixed and cannot be rotated, the quick release assembly 100 remains in the unlocked state. When the limiting member 20 is pushed out of the limiting hole 111K by the pushing member 30 to cancel the limiting fit, so that the rotating part 1311 can rotate relative to the connecting seat 110, the quick release assembly 100 can switch from the unlocked state to other states such as the locked state.

[0122] In actual application, the quick release assembly 100 is in an unlocked state through the limited cooperation between the limit member 20 and the limit hole 111K, and accordingly, the unlocking operation member 131 does not squeeze the two clamp arms 120, and thus the two clamp arms 120 are in a relaxed state. Therefore, when assembling the quick release assembly 100 and the structural member 200, the quick release assembly 100 can be directly pressed toward the structural member 200, and the structural member 200 can easily squeeze the two clamp arms 120 apart and be installed into the set groove 10. Moreover, after the structural member 200 is installed in place in the set groove 10, the structural member 200 will squeeze the push member 30 to retract it into the limit hole 111K, and the push member 30 will push the limit member 20 out of the limit hole 111K to cancel the stop limit of the rotating part 1311. When the stop limit of the rotating part 1311 is cancelled, under the elastic force of the first elastic member 132, the rotating part 1311 rotates toward the locking position, so that the pressure-applying part 1313 squeezes the pressure-receiving end 122 of the clamping arm 120, and the clamping arm 120 clamps the structural member 200. The quick-release assembly 100 automatically switches from the unlocked state to the locked state, which is simple to operate, easy to use, and labor-saving.

[0123] In addition, after the quick-release assembly 100 and the structural member 200 are separated, the user can manually operate the lever portion 1312 to drive the rotating portion 1311 to rotate, so that the limiting member 20 is inserted into the limiting hole 111K to form a limiting fit, that is, the quick-release assembly 100 is pre-switched and maintained to the unlocked state, which is convenient for the next assembly operation.

[0124] In some embodiments, reference Figure 3 and Figure 4 , the clamp arm 120 is provided with a first magnetic attraction member 40, and the first magnetic attraction member 40 is located at the pressure-receiving end 122 of the clamp arm 120;

[0125] The connecting seat 110 is provided with a second magnetic member 50 , which is opposite to the first magnetic member 40 and exerts a magnetic force on the first magnetic member 40 , and the direction of the magnetic force is the same as the direction in which the unlocking operating member 131 squeezes the pressed end 122 .

[0126] In this embodiment, one of the first magnetic member 40 and the second magnetic member 50 can be a magnet block, and the other can be a metal block that can be magnetically attracted, or both can be magnet blocks, according to actual needs. Among them, the pressure-receiving end 122 of the clamp arm 120 is provided with a groove that is compatible with the first magnetic member 40, and the first magnetic member 40 is accommodated in the groove. The direction of the magnetic attraction force generated by the second magnetic member 50 on the first magnetic member 40 is the same as the direction of the extrusion force applied by the unlocking operating member 131 to the pressure-receiving end 122.

[0127] That is, the design of the first magnetic member 40 and the second magnetic member 50 closely cooperates with the unlocking operating member 131 and works together. Specifically, during the design process, the combined effect of the magnetic attraction force and the squeezing force of the unlocking operating member 131 is fully considered. Through mechanical analysis and simulation calculations, the magnitude and direction of the magnetic attraction force of the magnetic member are determined so that it cooperates with the squeezing force applied by the unlocking operating member 131 to the compressed end 122 of the clamping arm 120 to jointly enhance the clamping force of the clamping arm 120. For example, in the locked state, the squeezing force of the unlocking operating member 131 and the magnetic attraction force of the magnetic member act on the compressed end 122 of the clamping arm 120 at the same time, so that the clamping arm 120 can clamp the structural member 200 more tightly and improve the stability of the connection.

[0128] The present invention also proposes a photographic accessory, which includes an accessory body and a quick-release assembly 100 as described in the aforementioned embodiment, and a connecting seat 110 is connected to the accessory body.

[0130] In some embodiments, reference Figure 1 and Figure 2 , the connecting seat 110 can slide relative to the structural member 200 along the length direction of the structural member 200;

[0131] The structural member 200 is provided with a plurality of positioning grooves 200C, which are arranged at intervals along the length direction of the structural member 200 . The connecting seat 110 is provided with a positioning portion 110B, which is used to snap into the positioning grooves 200C to position the connecting seat 110 .

[0132] In this embodiment, the quick release assembly 100 can slide relative to the structural member 200 through the connecting seat 110 to adjust its installation position on the structural member 200. After moving to the pre-adjusted position, the connecting seat 110 is positioned by the positioning portion 110B being inserted into the positioning groove 200C, and then the structural member 200 is clamped by the quick release assembly 100 to achieve the connection and assembly of the two, which helps to improve the position accuracy of the quick release assembly 100 on the structural member 200 and the connection stability between the quick release assembly 100 and the structural member 200. There can be two positioning portions 110B, and the two positioning portions 110B are spaced at opposite ends of the connecting seat 110 along the sliding direction of the connecting seat 110.
