[0020] The quick-release structures of existing camera gimbals and other fixed devices generally lack a design for quick locking. The few structures that do have quick locking also lack a safety mechanism, making them easy to be released under external interference or misoperation, which can cause the camera equipment to become loose or fall.
[0021] This application discloses a quick-release structure 100 for a photographic device, referring to... Figure 1 , Figure 3 and Figure 7 , Figure 1 This is a schematic diagram of the quick-release structure 100 of a photographic device in one embodiment of this application; Figure 3 This is a schematic diagram of the quick-release structure 100 of a photographic device in one embodiment of this application; Figure 7 for Figure 1 A schematic diagram of the base 110 in the quick-release structure 100 of the photographic equipment. In some embodiments, the quick-release structure 100 of the photographic equipment includes a base 110, a clamping member 120, a locking mechanism 130, and a limiting member 140. The base 110 has a receiving cavity 111, and strip-shaped protrusions 1121 are spaced apart on both sides of the main plane of the base 110. One of the protrusions 1121 has a first opening 1122, which communicates with the receiving cavity 111. The clamping member 120 is partially disposed in the receiving cavity 111 and can move along the spacing direction of the two protrusions 1121. One end of the clamping member 120 is movably inserted through the first opening. The opening 1122 is used to clamp the photographic equipment; the locking mechanism 130 includes a driving member 131 and an operating member 132. The driving member 131 is installed in the receiving cavity 111 and is used to push the clamping member 120 to move so that it can move through one end of the first opening 1122 to clamp or unlock the photographic equipment; the operating member 132 is located on one side of the boss 1121 and is linked with the driving member 131; the limiting member 140 is movably disposed in the receiving cavity 111, and a limiting structure is provided between the limiting member 140 and the locking mechanism 130 for engaging or releasing the operating member 132.
[0022] In this embodiment, the base 110 is the base of a quick-release structure, specifically including a receiving cavity 111 with an open top surface and a cover plate 112 connected to the top surface. The receiving cavity 111 is used to house the clamping member 120, the locking mechanism 130, and the limiting member 140, achieving a space-saving effect and making the quick-release structure more compact overall. The upper surface of the cover plate 112 is used to support the photographic equipment, and the upper surface of the cover plate 112 is also provided with two strip-shaped protrusions 1121. One of the protrusions 1121 has a first opening 1122 for one end of the clamping member 120 to pass through. One end of the clamping member 120 and the other strip-shaped protrusion 1121 jointly clamp the photographic equipment. In a preferred embodiment, the facing surfaces of one end of the clamping member 120 and the other strip-shaped protrusion 1121 match the shape of the two side surfaces of the dovetail plate of the photographic equipment to adapt to clamping the dovetail plate of the photographic equipment.
[0023] The clamping member 120 is a component that cooperates with another strip-shaped boss 1121 to clamp and fix the photographic equipment. The clamping member 120 is movably disposed in the receiving cavity 111 in the interval direction between the two bosses 1121, so that the end of it exposed outside the first opening 1122 can also reciprocate along the interval direction between the two bosses 1121, so as to achieve the effect of clamping and fixing or unlocking the photographic equipment in cooperation with the other boss 1121. The locking mechanism 130 is a component that drives the clamping member 120, including a driving member 131 disposed in the receiving cavity 111 to directly push the clamping member 120, and an operating member 132 linked with the driving member 131. The operating member 132 is located on one side of the boss 1121. Driving the operating member 132 causes the driving member 131 to push the clamping member 120, so that the exposed end of it approaches or moves away from the other boss 1121, thereby achieving the effect of clamping or unlocking the photographic equipment.
[0024] The limiting member 140 is a component of the operating member 132 of the locking mechanism 130. The limiting member 140 is movably disposed in the receiving cavity 111. A limiting structure is provided between the limiting member 140 and the locking mechanism 130. The limiting structure can be a snap-fit structure, a plug-in structure, or other detachable structure, as long as it can achieve the effect of fastening or releasing the operating member 132. When the operating member 132 is fastened to the limiting member 140 through the limiting structure, if you want to move the operating member 132, you need to first release the limiting structure between the two before you can move the operating member 132. This prevents the operating member 132 from being released by accidental operation or external force interference, which would cause the clamping member 120 to move away from the other protrusion 1121, resulting in the accidental drop of the camera equipment, damage to property, or accidental injury to the operator.
[0025] The quick-release structure 100 of the photographic equipment in this application includes a base 110, a clamping member 120, a locking mechanism 130, and a limiting member 140. The base 110 has a receiving cavity 111. Two protrusions 1121 are spaced apart on both sides of the main plane of the base 110. One of the protrusions 1121 has a first opening 1122 for one end of the clamping member 120 to pass through. The clamping member 120 is moved by the operating member 132 of the locking mechanism 130 in conjunction with the driving member 131, so that one end of the clamping member 120 moves through the first opening 1122 in the spaced direction between the two protrusions 1121, thereby clamping or unlocking the photographic equipment and finally achieving the quick-release effect of the photographic equipment. Furthermore, a limiting member 140 is movably disposed within the receiving cavity 111. A limiting structure is provided between the limiting member 140 and the locking mechanism 130 to engage or release the operating member 132. When the operating member 132 is engaged by the limiting member 140, in order to drive the operating member 132, the limiting structure between the limiting member 140 and the operating member 132 must first be released to prevent the operating member 132 from being accidentally operated and releasing the photographic equipment, thereby improving the safety of using the photographic equipment.
[0026] Reference Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of one embodiment of the quick-release structure 100 of the photographic equipment of this application. Figure 6 for Figure 5 A cross-sectional view at point AA. In some embodiments, one end of the limiting member 140 is movably connected to the receiving cavity 111, and the other end of the limiting member 140 is provided with a hook 141. One end of the operating member 132 is provided with a slot 1321 facing the limiting member 140. The hook 141 cooperates with the slot 1321 to engage or release the operating member 132.
[0027] In this embodiment, one end of the limiting member 140 is movably connected to the receiving cavity 111. Specifically, the movable connection can be that one end of the limiting member 140 is a cylindrical structure, and a cylindrical groove is opened at the bottom of the receiving cavity 111, so that one end of the limiting member 140 can rotate in the cylindrical groove, thereby enabling the other end of the limiting member 140 to rotate relative to the bottom of the receiving cavity 111, that is, the hook 141 can rotate relative to the bottom of the receiving cavity 111. One end of the operating member 132 has a slot 1321 opened on the surface facing the limiting member 140. When it is necessary to fix the operating member 132, the limiting member 140 rotates relative to the bottom of the receiving cavity 111, so that the hook 141 and the slot 1321 are engaged and connected, thereby realizing the engagement connection between the limiting member 140 and the operating member 132, preventing the operating member 132 from being accidentally operated and unlocking the photography equipment.
[0028] In some embodiments, such as Figures 1 to 4 As shown, Figure 2 for Figure 1 A schematic diagram of the quick-release structure 100 of the photographic equipment with the top cover removed. Figure 4 for Figure 3 A schematic diagram of the quick-release structure 100 of the photographic equipment with the top cover removed. The receiving cavity 111 includes opposite front and rear ends and opposite left and right sides. The operating member 132 is located on the left or right side of the receiving cavity 111. One end of the operating member 132 is located inside the receiving cavity 111 and is rotatably connected to the rear end of the receiving cavity 111, and the other end is close to the front end of the receiving cavity 111.
[0029] In this embodiment, one end of the operating member 132 is located inside the receiving cavity 111 and is rotatably connected to the rear end of the receiving cavity 111. Specifically, the rotatable connection can be achieved by setting a rotating shaft at the rear end of the receiving cavity 111, and having a shaft hole at one end of the operating member 132 that mates with the rotating shaft, thereby realizing the rotatable connection between the operating member 132 and the rear end of the receiving cavity 111. The other end of the operating member 132 is close to the front end of the receiving cavity 111 for easy operation by the user. The user only needs to apply force to the front end of the receiving cavity 111 to rotate the operating member 132. Furthermore, the operating member 132 is a lever arm, which is relatively long, making operation less strenuous.
[0030] In some embodiments, such as Figure 2 and Figure 5 As shown, one end of the limiting member 140 is housed in the receiving cavity 111, and a first elastic reset member 150 is provided between one end of the limiting member 140 and the receiving cavity 111; the other end of the limiting member 140 is exposed on the right front side or left front side of the receiving cavity 111 and is flush with the cavity wall of the receiving cavity 111.
[0031] In this embodiment, one end of the limiting member 140 is located inside the receiving cavity 111, and a first elastic reset member 150 is provided between one end of the limiting member 140 and the receiving cavity 111. Specifically, a partition is provided at the bottom of the receiving cavity 111, and the first elastic reset member 150 is provided between the partition and one end of the limiting member 140. The first elastic reset member 150 is a compression spring. When an external force drives the limiting member 140, the limiting member 140 rotates relative to one end, the hook 141 disengages from the slot 1321 of the operating member 132, the compression spring is compressed, and when the external force is lost, the compression spring recovers its deformation, pushing the limiting member 140 to rotate in the opposite direction, thereby realizing the automatic reset of the limiting member 140. It is understood that, in a preferred embodiment, the edges of the slot 1321 and the hook 141 are provided with mutually cooperating guide slopes. Before the operating member 132 rotates to the snap-fit connection position, the guide slope of the edge of the slot 1321 pushes the guide slope of the edge of the hook 141, causing the limiting member 140 to rotate and the first elastic reset member 150 to compress. When the locking mechanism 130 is fully in the snap-fit connection position, the first elastic reset member 150 loses external force and recovers its deformation, pushing the hook 141 to snap into the slot 1321, thereby realizing the automatic reset of the hook 141.
[0032] The other end of the limiting member 140 is exposed on the right front or left front side of the receiving cavity 111. This exposed design facilitates user pressing. The specific position of the other end of the limiting member 140 is determined by the setting position of the operating member 132 to minimize the distance between the two actions of driving the limiting member 140 and driving the operating member 132. By designing the other end of the limiting member 140 flush with the cavity wall of the receiving cavity 111, flexible surfaces such as skin and gloves can press the other end of the driving limiting member 140, causing the limiting member 140 to rotate and disengage the hook 141 from the slot 1321, allowing the operating member 132 to move. However, hard surfaces cannot press the other end of the driving limiting member 140, further preventing accidental unlocking by hard surfaces and improving the safety of the quick-release structure 100 of the photographic equipment. It is understandable that, in a preferred embodiment, the other end of the limiting member 140 is recessed relative to the groove wall of the receiving cavity 111. In this case, it is necessary to insert a finger or other elongated structure to drive the other end of the limiting member 140, thereby further improving the safety effect.
[0033] In some embodiments, refer to Figure 7 The accommodating cavity 111 has a accommodating part 1111 on the left or right side for accommodating the operating member 132.
[0034] In this embodiment, a receiving portion 1111 for accommodating the operating member 132 is provided on the left or right side of the receiving cavity 111. The position of the receiving portion 1111 is the same as the orientation of the hook 141 of the limiting member 140, so that the unlocking action between the operating member 132 and the limiting member 140 and the subsequent rotation action of the operating member 132 are on the same line of motion, which facilitates user operation. The advantage of providing the receiving portion 1111 is that it makes the side surface of the operating member 132 flush with the side of the base 110, making the quick-release structure more compact and saving space.
[0035] In some embodiments, refer to Figure 7 The receiving portion 1111 is connected to the first opening 1122. When the operating member 132 moves away from the receiving portion 1111, one end of the clamping member 120 can retract into the receiving portion 1111 to move away from the photographic equipment.
[0036] In this embodiment, when the operating member 132 rotates away from the receiving portion 1111, it causes one end of the clamping member 120 to move away from the other boss 1121. One end of the clamping member 120 and the other boss 1121 on the base 110 lose their clamping force on the photographic device. However, since the perpendicular line between the contact point of the clamping member 120 and the photographic device is located inside the perpendicular line between the clamping member 120 and the center of the rotating shaft, the three form a hooking effect, which can prevent the photographic device from detaching due to a single upward pull. At this time, one end of the clamping member 120 is further driven towards the bottom of the receiving cavity 111, causing one end of the clamping member 120 to retract into the receiving portion 1111 through the first opening 1122. The photographic device is then removed from the hooking range of one end of the clamping member 120 and the other boss 1121. At this time, lifting the photographic device upward completes the disassembly action.
[0037] In some embodiments, such as Figure 2 As shown, the receiving cavity 111 is constructed with a guide groove 1112, and the clamping member 120 is partially housed in the guide groove 1112 and can move along the guide groove 1112; the driving member 131 is provided with an abutting part 1311 for abutting against the clamping member 120.
[0038] In this embodiment, a guide groove 1112 is formed within the receiving cavity 111, and the clamping member 120 is partially disposed within the guide groove 1112, so that the clamping member 120 can move along the guide groove 1112, thereby stabilizing the moving direction of the clamping member 120 and preventing the movement of the clamping member 120 from deviating, which would cause instability in clamping. An abutment portion 1311 is connected to the driving member 131, which abuts against the clamping member 120. The driving member 131 pushes the clamping member 120 to move in the spaced direction between the two bosses 1121 through the abutment portion 1311, thereby achieving the effect of clamping and unlocking the photographic equipment. Understandably, in a preferred embodiment, the other end of the clamping member 120 is rotatably connected to a rotating shaft. The rotating shaft is connected to an abutment portion 1311, and the abutment portion 1311 and the rotating shaft are threaded together. Rotating the abutment portion 1311 can adjust the distance between the rotating shaft and the driving member 131, thereby adjusting the distance between the clamping member 120 and another boss 1121. This achieves the effect of adjusting the tightness of the clamping of the photographic equipment and allows the quick-release structure 100 of this photographic equipment to be adapted to photographic equipment of different sizes, thus improving the applicability of the quick-release structure 100. Furthermore, a coil spring is sleeved on the outer periphery of the rotating shaft. When the rotating shaft is rotated by external force, the coil spring will be wound. When the external force is removed, the coil spring will restore its deformation, pushing the rotating shaft to reset, thereby causing the clamping member 120 to automatically rotate and reset, saving manpower and improving the ease of operation of the quick-release structure.
[0039] In some embodiments, such as Figure 2 As shown, the guide groove 1112 is arranged in the left and right direction along the receiving cavity 111; the driving member 131 is arranged in a bent shape, including a connecting section 1312 connected to the operating member 132 and a main section 1313 bent relative to the connecting section 1312, and the main section 1313 is provided with an abutment part 1311.
[0040] In this embodiment, the guide groove 1112 is arranged in the left-right direction of the receiving cavity 111, that is, in the interval direction of the two protrusions 1121. The clamping member 120 moves along the guide groove 1112, that is, moves in the interval direction of the two protrusions 1121, and moves closer to or away from the other protrusion 1121, thereby clamping or unlocking the photography device.
[0041] The other end of the operating member 132 is linked to the clamping member 120 through the driving member 131 and the abutment part 1311. The driving member 131 has an L-shaped bent design and includes a connecting section 1312 connected to the operating member 132 and a main section 1313 with the abutment part 1311. One end of the connecting section 1312 is rotatably connected to the other end of the operating member 132, one end of the main section 1313 is rotatably connected to the bottom of the receiving cavity 111, one end of the abutment part 1311 is connected to the middle of the main section 1313, and the other end is connected to the clamping member 120. When the operating member 132 rotates out of the receiving cavity 111 from the receiving part 1111, it drives the connecting section 1312 of the driving member 131 to move, thereby driving the main section 1313 of the driving member 131 to tilt away from the other boss 1121, driving the abutment part 1311 and the clamping member 120 to move away from the other boss 1121, that is, one end of the clamping member 120 moves away from the other boss 1121, thereby achieving the effect of the clamping member 120 and the other boss 1121 releasing the photographic equipment. When the operating member 132 rotates from outside the receiving cavity 111 to inside the receiving part 1111, it pushes the connecting section 1312 of the driving member 131 to move, thereby driving the main section 1313 of the driving member 131 to rotate towards the other boss 1121, driving the abutment part 1311 and the clamping member 120 to move towards the other boss 1121, that is, one end of the clamping member 120 moves towards the other boss 1121, thereby achieving the effect of clamping the photographic equipment by the clamping member 120 and the boss 1121.
[0042] In some embodiments, such as Figure 4 As shown, a second elastic reset member 160 is also provided between the driving member 131 and the clamping member 120.
[0043] In this embodiment, the second elastic reset member 160 is a compression spring. One end of the second elastic reset member 160 abuts against the driving member 131, and the other end abuts against the clamping member 120. When relative movement occurs between the driving member 131 and the clamping member 120, the second elastic reset member 160 deforms under force. When the external force is removed, the second elastic reset member 160 recovers its deformation, causing the driving member 131 and the clamping member 120 to automatically reset. It can be understood that, in a preferred embodiment, the second elastic reset member 160 is sleeved on the outer periphery of the abutment portion 1311 to guide the compression trajectory of the second elastic reset member 160 and prevent the second elastic reset member 160 from deflecting, causing the reset failure problem.
[0044] This application further discloses a fixing device for a photographic device, including the quick-release structure 100 of the photographic device as described above.
[0045] In this embodiment, the fixing device for the photography equipment includes, but is not limited to, devices that can detachably mount the photography equipment, such as camera gimbals, camera shoulder straps, and stabilizers.
