Description

Technical Field

[0001] The utility model belongs to the technical field of photography auxiliary accessories, and particularly relates to a quick-release structure. Background Art

[0002] During the shooting process of camera and other photographic equipment, the staff sometimes needs to add external functional accessories to the camera, such as microphone, flash, etc., according to the shooting requirements. Sometimes the camera needs to be installed on a head or tripod, and sometimes the camera needs to be removed from the head or tripod for use alone. In this way, the connection components connecting the camera and the photographic accessories (head, tripod or other functional components) are used. The connection components are often used for the rapid installation and removal of the camera and the installation accessories. The connection components on the market are generally set as an integrated unit, and the camera and the configured photographic accessories are connected by bolts respectively. When disassembly is required, the screws need to be removed to disassemble the camera from the photographic accessories, which is relatively troublesome.

[0003] For example, the patent with publication number CN113568259A discloses a disassembly and assembly component, which sets a handle on the side of the bottom shell and realizes disassembly and assembly between two fixing parts by rotating the handle. During disassembly and assembly, the staff needs to rotate the connecting component in the height direction to unlock it. With such a setting, during operation, the staff needs to hold the base of the connecting component with one hand and rotate the handle to the unlocking position with the other hand. The operation requires the cooperation of both hands, and the whole process is rather cumbersome. Utility Model Content

The two clamping members 31 and the trigger 32 are both movably arranged on the quick release base 2, and the two clamping members 31 are adjacent to the mounting groove A. The two clamping members 31 are used to install the quick release plate 1 in the mounting groove A; the trigger 32 is used to trigger the clamp 31, so that the quick release plate 1 is relaxed in the mounting groove A. In this embodiment, the clamp 31 can clamp the quick release plate 1 in the mounting groove A, and the trigger 32 can trigger the clamp 31 to unlock the quick release plate 1 from the mounting groove A, thereby realizing the quick disassembly and installation between the quick release plate 1 and the quick release base 2; and when unlocking, only one hand needs to press the trigger 32, and no two hands are required, which is more convenient and quick.

[0039] Furthermore, the plurality of clamping members 31 include a first clamping member 311 and a second clamping member 312, and the first clamping member 311 and the second clamping member 312 are respectively arranged on both sides of the trigger member 32, and when the trigger member 32 moves relative to the quick release base 2, the first clamping member 311 and the second clamping member 312 can move toward each other or move away from each other. In this embodiment, when the trigger member 32 is pressed inwardly, the first clamping member 311 and the second clamping member 312 can move away from each other, leaving installation space, and the quick release plate 1 can be quickly installed in the installation slot A. At this time, the trigger member 32 is released, and the first clamping member 311 and the second clamping member 312 can move toward each other, so that the quick release plate 1 is stably installed in the installation slot A. At this time, other photographic equipment can be installed through the quick release structure in this application. When the user needs to disassemble the photographic equipment, for example, to remove the camera kit from the tripod, the user can press the trigger again, and the first clamping member 311 and the second clamping member 312 can move in directions away from each other, leaving installation space, so that the quick release plate 1 can be quickly removed from the installation slot A, thereby separating the camera kit and the tripod. In another embodiment, when the reverse buckle method is adopted (i.e., the quick release plate 1 is buckled outward), when the trigger 32 is pressed, the first clamping member 311 and the second clamping member 312 can move in directions close to each other, leaving installation space, and the quick release plate 1 can be quickly installed in the installation slot A. At this time, the trigger 32 is released, and the first clamping member 311 and the second clamping member 312 can move in directions away from each other and be reversely clamped on the quick release plate 1.
