Description

Technical Field

[0001] This utility model relates to the field of shooting auxiliary equipment technology, specifically to an adjustable quick-assembly and disassembly component. Background Technology

[0002] With the development of economic life, more and more people have begun to fall in love with taking photos and videos. As a result, more and more photography accessories have begun to be used. When using them, users usually need to install photography accessories at a certain work position, that is, install them at the target mounting position, such as installing a monitor on the truss of the director's vehicle.

[0003] To avoid delaying the shooting schedule, photographic accessories need to be quickly installed at the work station. This is especially important for heavier accessories, where the installation speed must be increased to reduce the workload of the operators. Therefore, in actual operation, appropriate quick-release components are used to enable the rapid installation of photographic accessories at the work station. Generally, quick-release components include a quick-release base and at least a hook-shaped part that can be reciprocated and installed on the quick-release base. They also include a locking mechanism. The locking mechanism drives the hook-shaped part to cooperate with the quick-release base to clamp and lock the external structure, and the locking mechanism abuts against the quick-release base to lock the hook-shaped part in the locked position.

[0004] In actual use, different users have different requirements for the tightness of the locking mechanism of the quick-release assembly. In order to improve the user experience, it is necessary to design a quick-release assembly with an adjustable tightness of the locking mechanism. Utility Model Content

[0005] This utility model provides an adjustable quick-release assembly with adjustable tightness of the locking mechanism.

[0006] This utility model provides an adjustable quick-assembly / disassembly component, which includes:

[0007] A quick-release bracket includes a base body and an adjusting member, the base body having a receiving groove for receiving an external structure, the receiving groove having a stop wall for stopping the external structure, and the adjusting member being threadedly mounted on the base body;

[0008] A hook-shaped component is disposed opposite to the stop wall and is used to engage with the stop wall to lock the external structure.

[0009] A locking mechanism includes an operating member and a connecting member. The connecting member is connected between the hook-shaped member and the operating member. At least one of the hook-shaped member and the connecting member is movably mounted on the quick-release seat. The connecting member and the operating member are rotatably connected. One of the operating member and the adjusting member contacts and engages with the other through a curved surface structure. The curved surface structure extends away from the stop wall, so that when the operating member moves relative to the adjusting member, it can drive the hook-shaped member to approach or move away from the stop wall through the connecting member to lock or release the external structure.

[0010] The direction in which the hook-shaped member is driven to move by the connector is defined as the adjustment direction, and the adjustment member is rotatably mounted on the base along the adjustment direction.

[0011] In one technical solution, the adjusting member includes a large-diameter section and a small-diameter section. The small-diameter section has an external thread that connects to the seat body. The seat body has a groove at the opening of a threaded hole into which the adjusting member is screwed. The groove is used to accommodate the large-diameter section of the adjusting member. The groove wall has a notch, through which a portion of the large-diameter section of the adjusting member is exposed. The outer circumferential surface of the large-diameter section has a force-applying structure for the operator to apply force.

[0012] In one technical solution, the force-applying structure is a concave-convex structure on the outer circumferential surface of the large-diameter section.

[0013] In one technical solution, the edge of the notch has a rounded corner structure.

[0014] In one technical solution, the orientation of the notch is opposite to the orientation of the opening of the receiving groove.

[0015] In one technical solution, the connector is rod-shaped and passes through a channel opened on the base. The center of the adjusting member is a through hole, which communicates with the channel, and the connector extends out of the through hole.

[0016] In one technical solution, the hook-shaped member is connected to one end of the connector, the operating member is an operating handle and is hinged to the other end of the connector, the operating handle has a cam structure that abuts against the adjusting member, and the cam surface of the cam structure constitutes the curved surface structure.

[0017] In one technical solution, a locking pawl is hinged to the operating handle, and an elastic element is provided between the locking pawl and the operating handle to drive the locking pawl to press against the connecting member. A middle locking groove is provided on the connecting member, and the locking pawl and the middle locking groove cooperate to form a ratchet and pawl structure. When the locking pawl and the middle locking groove are engaged, the distance between the hook-shaped member and the stop wall is adapted to the size of the external structure so as to constrain but not lock the external structure.

[0018] In one technical solution, the cam surface includes an anti-rotation engagement portion. When the locking pawl engages with the intermediate locking groove, the anti-rotation engagement portion of the operating handle engages with the adjusting member to prevent the operating handle from rotating.

[0019] In one technical solution, the hook-shaped member is hinged to the locking mechanism, and an elastic driving member is provided between at least one of the locking mechanism and the quick-release seat and the hook-shaped member. The elastic driving member is used to drive the hook-shaped member to reset towards the stop wall.

[0020] The beneficial effects of this utility model are:

[0021] According to the aforementioned adjustable quick-release assembly, the stop wall and hook-shaped part on the quick-release base cooperate to clamp the external structure under the drive of the locking mechanism. When it is necessary to install photographic accessories onto the external structure of the working position, such as the quick-release plate of the working position, the photographic accessories can be connected and installed on the quick-release base, that is, the photographic accessories are installed on the adjustable quick-release assembly, and then the adjustable quick-release assembly is engaged with the quick-release plate of the working position, so that the quick-release plate of the working position enters between the stop wall and the hook-shaped part. Then, the hook-shaped part is locked in the locking position by the locking mechanism, which quickly realizes the connection between the quick-release plate and the adjustable quick-release assembly, thereby realizing the quick installation of photographic accessories in the working position. If the working position has a structure that connects to the adjustable quick-release assembly, the adjustable quick-release assembly can be connected to the working position, and the photographic accessories are connected to the quick-release plate. The quick installation of the quick-release plate on the quick-release base realizes the quick installation of photographic accessories in the working position. For different users, the position of the adjusting part can be changed by screwing the adjusting part in and out, thus adjusting the tightness of the operating part to meet the user experience of different users.

[0045] In this invention, the hook-shaped component of the adjustable quick-release assembly cooperates with the stop wall, and a locking mechanism is provided for the hook-shaped component. The locking mechanism can lock the hook-shaped component in the locked position to lock the external structure between the stop wall and the hook-shaped component. It can also be unlocked to allow the hook-shaped component to reach the unlocked position to release the constraint on the external structure, allowing the external structure to move out from between the hook-shaped component and the stop wall. In this way, the locking mechanism drives the hook-shaped component to cooperate with the stop wall, realizing the quick installation and removal of the external structure on the quick-release assembly, improving the convenience of installing and removing photographic accessories at the target working position. The operating component cooperates with the adjusting component, and the adjusting component can be adjusted in position, thus changing the tightness of the operating component to meet the operating experience of different users.

[0046] An embodiment of an adjustable quick-assembly / disassembly component of this utility model:

[0047] Please refer to Figure 1 In one embodiment, the adjustable quick-release assembly is used to mount a camera accessory onto an external structure, specifically a truss on a director's vehicle 1100. The truss is a beam-type quick-release plate 100 mounted on the director's vehicle. In use, the quick-release plate 100 extends horizontally in length, vertically in width, and horizontally in thickness. The camera accessory is a monitor 200, which is mounted onto the quick-release plate 100 using the adjustable quick-release assembly of this invention.

[0048] The adjustable quick-release assembly includes a quick-release mount 300, which has a mounting structure for connecting and installing the monitor 200. Please refer to [reference needed]. Figure 2 and Figure 3 , Figure 2 The diagram shows a portion of the quick-release plate 100. The quick-release seat 300 has a seat body 301, which has a receiving groove 3011 for accommodating the quick-release plate 100. The receiving groove 3011 has a stop wall 3012 for stopping the quick-release plate 100. Please refer to [reference needed]. Figure 4 The adjustable quick-release assembly also includes a hook-shaped part 400 that mates with the stop wall 3012.

[0049] Please refer to Figure 4 The stop wall 3012 and the hook-shaped member 400 are arranged opposite to each other. The hook-shaped member 400 and the stop wall 3012 form an installation space 500 that ultimately accommodates the quick-release plate 100. The shape of the installation space 500 can be a commonly used interface specification in the field of photography, such as Manfrotto, Arca, NATO, etc. In one embodiment, the stop wall 3012 is an inclined wall that is inclined toward the location of the hook-shaped member 400. In this way, the stop wall 3012 and the hook-shaped member 400 form a trapezoidal cross-section installation space 500 with a small opening and a large cavity, which matches the trapezoidal cross-section of the quick-release plate 100.

[0050] In some other embodiments, the cross-sectional shape of the stop wall can also be an inverted L-shape, and the specific shape and bending angle of the hook-shaped member can be matched accordingly, so that the cross-sectional shape of the installation space is convex, which can also be matched with the quick-release plate 100.

[0051] Please refer to Figure 2 , Figure 4 and Figure 5 In order for the hook-shaped part 400 to cooperate with the stop wall 3012 to clamp the quick-release plate 100, the adjustable quick-release assembly also includes a locking mechanism 600. The locking mechanism 600 is connected to the hook-shaped part 400, and the movement of the locking mechanism 600 drives the hook-shaped part 400 to move toward the stop wall 3012. The hook-shaped component 400 has a locking position and an unlocking position during its travel. When the hook-shaped component 400 is brought to the locking position by the locking mechanism 600, the hook-shaped component 400 cooperates with the stop wall 3012 to lock the quick-release plate 100. When the hook-shaped component 400 is in the unlocking position, the quick-release plate 100 can be moved out from between the hook-shaped component 400 and the stop wall 3012. In the unlocking position, the minimum distance between the hook-shaped component 400 and the stop wall 3012 is not less than the maximum width of the quick-release plate 100. Thus, when it is necessary to separate the adjustable quick-release assembly from the quick-release plate 100, the quick-release plate 100 can be moved out from between the hook-shaped component 400 and the stop wall 3012 simply by moving the adjustable quick-release assembly. To improve the locking force, in some embodiments, the surface of the hook-shaped component 400 that mates with the quick-release plate has a protruding structure 402.

[0052] Please refer to Figure 4 and Figure 5 The hook-shaped component 400 is hinged to the locking mechanism 600 via a hinge shaft 700. The locking mechanism 600 includes an operating handle 601 and a connecting member 602. The connecting member 602 is rod-shaped and reciprocally mounted on the quick-release seat 300. The hook-shaped component 400 is hinged to the connecting member 602 via the hinge shaft 700. In one embodiment, the hook-shaped component 400 and the operating handle 601 are connected at both ends of the connecting member 602. An elastic driving member is provided between the hook-shaped component 400 and the quick-release seat 300 to drive the hook-shaped component 400 to rotate toward the locking position. In one embodiment, the elastic driving member is a torsion spring 800 sleeved on the hinge shaft 700. One end of the torsion spring 800 abuts against the hook-shaped component 400, and the other end abuts against the quick-release seat 300. In some other embodiments, the other end of the torsion spring 800 may not engage with the quick-release seat 300, but may instead engage with the connector 602; alternatively, one end may engage with both the connector 602 and the quick-release seat 300, while the other end engages with the hook-shaped member. Of course, the elastic drive element may also be a coil spring disposed between the hinge shaft 700 and the hook-shaped member 400, or a tension spring connected between the hook-shaped member 400 and the connector 602. In some other embodiments, the hook-shaped member 400 may also be fixedly connected to the locking mechanism 600.

[0053] The operating handle 601 is a manually operated component, hinged to the connecting member 602. The operating handle 601 has a cam structure 6011. During operation, the operating handle 601 engages with the quick-release seat 300 via the cam structure 6011. Naturally, the operating handle 601 has an operating handle locking position corresponding to the locking position of the hook-shaped member 400 during its rotational stroke. Please refer to [reference needed] for this state. Figure 6 At this time, the operating handle 601 is approximately at a 180-degree position.

[0054] The operating handle 601 also has an operating handle unlocking position corresponding to the unlocking position of the hook-shaped part 400 during its rotation stroke. Please refer to the following for this state. Figure 7 At this time, the operating handle 601 is approximately at the 0-degree position. When the small-diameter portion of the cam structure 6011 abuts against the quick-release seat 300, the operating handle 601 is in the unlocked position and the hook-shaped part 400 is in the unlocked position. When the large-diameter portion of the cam structure 6011 abuts against the quick-release seat 300, the operating handle 601 is in the locked position and the hook-shaped part 400 is in the locked position.

[0055] In use, the operating handle 601 can be rotated to a position between the operating handle unlock position and the operating handle locking position. In one embodiment, this position can be approximately 90 degrees. At this time, the hook-shaped member 400 reaches the position between the locking position and the unlock position under the drive of the locking mechanism. Please refer to [reference needed]. Figure 2 At this time, the distance between the end 401 of the hook-shaped part 400 and the stop wall 3012 is less than the width of the quick-release plate 100. When installing the quick-release plate 100, please refer to... Figure 8 First, one side of the quick-release plate 100 can be installed to mate with the stop wall 3012. At this time, the other side of the quick-release plate 100 will press against the end 401 of the hook-shaped member 400. Since the hook-shaped member 400 is hinged to the connector 602, when the quick-release plate 100 is pressed into the installation space 500, it can force the hook-shaped member 400 to rotate and move away from the quick-release plate 100. After the quick-release plate 100 is installed in place, under the drive of the torsion spring 800, the hook-shaped member 400 rotates toward the quick-release plate 100 to reset. Please refer to the following for this state. Figure 9 .

[0056] After resetting, the hook-shaped component 400 cooperates with the stop wall 3012 to constrain the quick-release plate 100 within the installation space 500. Through the cooperation between the side slope of the quick-release plate 100 and the inner side of the hook-shaped component 400, the quick-release plate 100 can be constrained from easily coming out of the installation space 500. At the same time, since the hook-shaped component 400 does not lock the quick-release plate 100, the monitor 200 can slide along the quick-release plate 100 together with the adjustable quick-release assembly. This allows the installation position of the monitor 200 to be adjusted while making it difficult for the monitor 200 to come off the quick-release plate 100.

[0057] In another scenario, when installing the monitor 200 onto the quick-release plate 100, the operating handle 601 can be turned to an intermediate position between the unlocked and locked positions, such as the aforementioned approximately 90-degree position. Then, the assembly consisting of the monitor 100 and the adjustable quick-release components can be installed onto the quick-release plate 100. Once the quick-release plate 100 is inside the installation space 500, there is no need to lift the monitor 100, freeing the operator's hands to move the monitor 200 to the appropriate position along the quick-release plate 100. Then, the operating handle 601 can be turned to the locked position to lock the quick-release plate 100. This allows for quick installation of the monitor 200 at the target installation position while reducing the time the operator spends lifting the monitor 200, thus reducing workload. This method is particularly suitable for installing heavy photographic accessories at the target installation position.

[0058] The term "middle position" refers to the position between the locked and unlocked positions of the operating handle. Correspondingly, it refers to the position of the hook-shaped part between the unlocked and locked positions. It does not specifically refer to the exact middle position. In some embodiments, the middle position can be changed to other non-90-degree positions between the unlocked and locked positions of the operating handle, as long as the above-mentioned operational requirements are met, such as the 60-degree position, the 100-degree position, etc.

[0059] In one embodiment, please refer to Figure 5 , Figure 10 and Figure 13 The operating handle 601 and the connecting member 602 have a locking structure. The locking structure includes a locking pawl 900 hinged to the operating handle, and an elastic element between the locking pawl 900 and the operating handle 601. The elastic element can be a compression spring pressed between the operating handle 601 and the locking pawl 900, a torsion spring disposed between the locking pawl 900 and the operating handle 601, or a tension spring connected between the locking pawl 900 and the operating handle 601. The elastic element drives the locking pawl 900 to press against the connecting member 602. The locking structure also includes an intermediate locking groove 6021 formed on the connecting member 602, so that the locking pawl 900 and the connecting member 602 cooperate to form a ratchet and pawl structure, restricting the operating handle 601 to rotate only from the operating handle unlock position to the operating handle locked position. When it is necessary for the operating handle 601 to move from the operating handle locked position to the operating handle unlock position, the end of the locking pawl 900 away from the connecting member 602 is pressed to disengage the locking pawl 900 from the intermediate locking groove 6021.

[0060] To further improve the stability of the operating handle 601 when locked in the intermediate position, the cam surface of the cam structure 6011 has an anti-rotation engagement portion 60111. The anti-rotation engagement portion 60111 has a planar structure. When the operating handle 601 is rotated to the intermediate position, the operating handle 601 engages with the quick-release seat 300 through the anti-rotation engagement portion, further improving the stability of the operating handle 601 in the intermediate position. In other embodiments, the anti-rotation engagement portion can also be a raised dot on the cam surface. Correspondingly, a groove that engages with the dot is provided on the part of the quick-release seat that engages with the operating handle. When the operating handle is rotated to the intermediate position, the dot is embedded in the groove.

[0061] In order to ensure that the operating handle 601 can be stably maintained in the operating handle locking position, a locking groove 6023 is also formed on the connector 602 at the position corresponding to the operating handle locking position. In this way, when the operating handle 601 is in the operating handle locking position, the operating handle can be locked to achieve reliable position maintenance and prevent accidental locking.

[0062] In other embodiments, the locking structure can also be other structures, such as a pin-type locking structure. For example, a pin hole is provided on the operating handle 601, and a locking hole is provided on the connector 602. The position of the locking hole corresponds to the target position to be locked by the operating handle 601. When the operating handle 601 is turned to the target position, the pin hole and the locking hole are aligned, and a locking pin is inserted into the pin hole and the locking hole to lock the operating handle 601 in the intermediate position. For the locking mechanism, it can also be a structure that does not involve the operating handle and the connector cooperating. For example, it can be a structure that involves the locking nut and the screw. The screw acts as a connector, with one end connected to the hook-shaped member and the other end cooperating with the locking nut. When the end face of the locking nut abuts against the quick-release seat 300, the hook-shaped member 400 is locked in the locked position.

[0063] Please refer to Figure 3 , Figure 10 and Figure 11The base 301 has a mounting cavity 3013 for accommodating the hook-shaped component 400. The mounting cavity 3013 extends through the base 301. The end 401 of the hook-shaped component 400 protrudes through an opening at one end of the mounting cavity 3013 to engage with the stop wall 3012. The quick-release base 300 has a cover plate 302 installed at the other end opening of the mounting cavity 3013. After the hook-shaped component 400 is installed in the mounting cavity 3013, the cover plate 302 is installed in place. After installation, the torsion spring 800 abuts against the cover plate 302. This structure allows the hook-shaped component 400, the torsion spring 800, and the connection structure between the hook-shaped component 400 and the connector 602 to be concealed within the quick-release base 300. This not only improves aesthetics but also protects the hook-shaped component 400, the connection structure between the hook-shaped component 400 and the connector 602, and the torsion spring 800. To facilitate assembly, a through hole 1000 is provided in the cavity wall of the mounting cavity 3013. During assembly, the hook-shaped member 400 and the connecting member 602 can be aligned inside the mounting cavity 3013, and the hinge shaft 700 can be inserted through the through hole 1000 to hinge the hook-shaped member 400 and the connecting member 602 together. In some other embodiments, the mounting cavity may not be provided on the base, and the hook-shaped member may be exposed on the outside of the base.

[0064] In one embodiment, please refer to Figure 10 In addition to the base body 301 and the cover plate 302, the quick-release bracket 300 also includes an adjusting component 303. Please refer to [the documentation / reference]. Figure 11 The receiving groove 3011, the stop wall 3012, and the mounting cavity 3013 are located on the base 301. The base 301 has a channel communicating with the mounting cavity 3013, and the connector 602 is installed in this channel to enable the locking mechanism to reciprocate on the quick-release base 300. In other embodiments, the hook-shaped member can also be reciprocated linearly along a set track and installed on the base, with the connector fixedly connected to the hook-shaped member, and the connector not directly assembled with the base.

[0065] Please refer to Figure 12 The adjusting member 303 has a large diameter section 3031 and a small diameter section 3032. The small diameter section 3032 has threads formed on its outer side. The channel opening of the mounting connector 602 has a groove 3014, and the end of the channel that connects to the groove 3014 has an internal thread to form a threaded hole into which the adjusting member 303 can be screwed.

[0066] The direction in which the hook-shaped part 400 is driven by the connector 602 is defined as the adjustment direction. The adjustment part 602 is screwed in and out of the base 301 along the adjustment direction. The adjustment part 303 has a through hole 3033 in the middle for the connector 602 to pass through. The operating handle 601 and the adjustment part 303 are engaged in abutting cooperation. Specifically, the cam surface of the cam structure 6011 of the operating handle 601 is a curved surface structure that cooperates with the adjustment part 303. The curved surface structure extends away from the stop wall 3012. When different users use this adjustable quick-release assembly, they can screw the adjustment part 303 outward or inward to adjust the tightness of the operating handle 601 when it is in motion, so as to meet the operating experience of different users.

[0067] In other embodiments, the locking mechanism may have other structures, and correspondingly, the structure of the adjusting member may also be changed. For example, the adjusting member may have a cylindrical portion extending out of the seat 301, and two hollowed-out spiral grooves may be opened on the cylindrical wall of the cylindrical portion. The spiral grooves extend away from the stop wall 3012, and the spiral surface of the spiral grooves is a curved surface structure. The end of the connecting member of the locking mechanism extends into the cylindrical portion, and the operating member is a crossbar perpendicular to the connecting member. The two ends of the crossbar extend out through the two hollowed-out grooves for manual operation, and the crossbar is rotatably mounted on the connecting member around the axis of the connecting member. When the hook-shaped member 400 needs to lock the quick release plate 100, the operating crossbar moves the crossbar away from the seat 301 along the spiral surface of the spiral groove, so that the connecting member drives the hook-shaped member 400 to lock the quick release plate 100.

[0068] In one embodiment, the groove wall of the groove 3014 has a notch 30141, allowing the large-diameter section 3031 of the adjusting member 303 to be partially exposed. The outer peripheral surface of the large-diameter section 3031 of the adjusting member 303 has a concave-convex structure (not shown in the figure), which serves as a force-applying structure for the operator to apply force. The operator can drive the adjusting member 303 to rotate by rubbing its fingertips against the large-diameter section 3031, thereby adjusting the amount of screwing of the adjusting member 303 into the seat 301. In other embodiments, the force-applying structure may also be blind holes spaced apart on the outer peripheral surface of the large-diameter section 3031 of the adjusting member 303. The operator can insert a rod-shaped tool into the blind holes to apply force to adjust the adjusting member.

[0069] To prevent fingers from being cut, the edge of the notch 30141 has a rounded corner structure 30142. In one embodiment, please refer to... Figure 11The notch 30141 faces opposite to the opening of the mounting space 500, which prevents accidental contact with the adjusting member 303 when installing the quick-release plate 100. In some other embodiments, the groove wall may not have a notch. In this case, the end face of the adjusting member 303 should have a structure that cooperates with a tool so that the adjusting member can be rotated and adjusted by the tool. Of course, the groove 3014 may not be formed on the quick-release base 300. In this case, the large diameter section 3031 of the adjusting member 303 is completely exposed, which makes adjustment more convenient, but it will also affect the simplicity of the overall structure of the adjustable quick-release assembly, and may also easily lead to accidental contact with the adjusting member 303, causing the adjusting member 303 to rotate and adjust accidentally.

[0070] In one embodiment, please refer to Figure 5 The connecting piece 602, which is installed in conjunction with the quick-release base 300, is a round rod structure 6022. The hook-shaped piece 400 is hinged to the round rod structure 6022. The round rod structure has a guide elongated hole 60221, and a guide pin 603 is fitted inside the guide elongated hole 60221. In order to install the guide pin 603, the quick-release base 300 has a guide pin mounting hole (not shown in the figure) that communicates with the channel for installing the connecting piece 602. During assembly, the connecting piece 602 is installed in the channel on the quick-release base 300, so that the guide elongated hole 60221 is aligned with the guide pin mounting hole. Then, the guide pin 603 is installed in the guide pin mounting hole and extends into the guide elongated hole 60221. Then, a plug is installed at the opening of the guide pin mounting hole to prevent the guide pin 603 from coming out. In some other embodiments, a guide elongated hole can be formed on the quick-release seat to connect the outside world and accommodate the connector. The guide pin 603 is fixedly installed on the round rod structure. During specific assembly, the connector can be installed into the channel first, so that the hole for installing the guide pin on the round rod structure of the connector is aligned with the guide elongated hole. Then, the guide pin 603 is fixedly installed on the connector through the guide elongated hole.

[0071] In one embodiment, a compression spring 604 is fitted onto the round rod structure 60221. One end of the compression spring 604 abuts against the quick-release seat 300, and the other end abuts against the hinge shaft 700. When the connecting member 602 moves towards the locking position with the hook-shaped member 400, the compression spring 604 is compressed and stores energy. When the operating handle 601 reaches the operating handle locking position, the counterforce exerted by the compression spring 604 on the connecting member ensures that the operating handle 601 remains stably in the operating handle locking position. Furthermore, after the locking mechanism is unlocked, the compression spring 604 can drive the locking mechanism, carrying the hook-shaped member 400, to move to the unlocked position. In other embodiments, the compression spring 604 can also be connected to the quick-release seat 300 and the hinge shaft 700.

[0072] In some other embodiments, the photographic accessory can also be other equipment, such as a camera, camcorder, etc. A quick-release plate can also be connected to the photographic accessory, and the quick-release mount can be connected to a structural component of the target mounting location, such as a tripod, thus enabling quick mounting and dismounting of the photographic accessory from the tripod.

[0073] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
