[0046] In this invention, the hook-shaped component of the 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 locking position to lock the external structure between the stop wall and the hook-shaped component. It can also unlock the hook-shaped component to reach the unlock 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 can drive 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.

[0047] An embodiment of a quick-assembly / disassembly component in this utility model:

[0048] Please refer to Figure 1 In one embodiment, the quick-release assembly is used to install a camera accessory on an external structure, specifically a truss on a director's vehicle 1100. The truss is a beam-type quick-release plate 100 installed 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 installed on the quick-release plate 100 using the quick-release assembly of this invention.

[0049] The 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 quick-release assembly also includes a hook-shaped part 400 that mates with the stop wall 3012.

[0050] 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.

[0051] 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.

[0052] 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 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 quick-release assembly from the quick-release plate 100, the quick-release assembly can be moved directly to move the quick-release plate 100 out from between the hook-shaped component 400 and the stop wall 3012. 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.

[0053] 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.

[0054] The operating handle 601 is hinged to the connecting member 602, and the operating handle 601 has a cam structure 6011. During operation, the operating handle 601 abuts against the quick-release seat 300 through 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 rotation stroke. Please refer to this state. Figure 6 At this time, the operating handle 601 is approximately at a 180-degree position.

[0055] 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.

[0056] 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 2At 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 .

[0057] 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 quick-release assembly. This allows the monitor 200 to be adjusted in its installation position while making it difficult for the monitor 200 to come off the quick-release plate 100.

[0058] 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 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.

[0059] 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.

[0060] In one embodiment, please refer to Figure 5 , Figure 10 and Figure 13The 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] Please refer to Figure 3 , Figure 10and Figure 11 The 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.

[0065] 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.

[0066] 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.

[0067] The direction in which the hook-shaped component 400 is driven by the connector 602 is defined as the adjustment direction. The adjustment component 602 is screwed in and out of the base 301 along the adjustment direction. The adjustment component 303 has a through hole 3033 in the middle for the connector 602 to pass through. The operating handle 601 and the adjustment component 303 are engaged in abutting cooperation. Thus, by adjusting the amount of screwing the adjustment component 303 into the threaded hole, the degree of slackness of the operating handle 601 when it is in motion can be changed, that is, the degree of slackness of the connector 602 can be adjusted. Specifically, after the adjustment component 303 is screwed outward, when the operating handle 601 is operated, the position of the connector 602 is adjusted so that when the connector 602 drives the hook-shaped component 400 to lock the quick-release plate 100, the feel is tighter, that is, more operating force is required. Conversely, the feel is looser, and less operating force is required, so as to meet the operating experience of different users.

[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 circumferential surface of the large-diameter section 3031 of the adjusting member 303 has an uneven structure (not shown in the figure). An 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. To prevent finger injuries, the edge of the notch 30141 has a rounded corner structure 30142. In one embodiment, please refer to... Figure 11 The 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 seat 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 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.

[0069] In one embodiment, please refer to Figure 5The 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.

[0070] 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.

[0071] 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.

[0072] 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.
