Description

Technical Field

[0001] The utility model relates to the field of quick-release components, in particular to a quick-release plate and a quick-release component. Background Art

[0002] In daily life, quick-release components are widely used in various fields. For example, corresponding quick-release components are used in the connection between two devices or components such as photographic devices, photographic stands, and display stands. To achieve the connection between the two devices, one of the devices is usually connected to the other device using a connecting component. For example, when a functional device is added to a photographic stand, the functional device is set on the photographic stand through the connecting component, thereby completing the installation and connection of the photographic stand and related equipment.

[0003] With the continuous advancement of photographic technology and the increasing diversification of photographic equipment, the quick release plate, as a key component connecting photographic equipment with supporting equipment such as tripods and gimbals, has become increasingly important. The quick release plate not only improves the efficiency of photographers when changing equipment or adjusting shooting angles, but also ensures the stability and safety of photographic equipment.

[0004] However, although the existing quick-release plates and quick-release assemblies meet the requirements of use to a certain extent, the installation limit accuracy of the quick-release seat and the quick-release plate needs to be strictly controlled, which requires high processing accuracy and leads to greater processing difficulty. When the processing accuracy error increases, it is easy to cause the connection between the quick-release plate and the quick-release seat to shake, thereby affecting the stability of the connection, which is not conducive to the stable connection between the quick-release plate and the quick-release seat.

[0005] The locking connection of the existing quick-release seat to the quick-release plate is generally achieved by rotating the quick-release plate through the rotation drive of the rotating shaft, or by locking the quick-release plate with the hook structure of the quick-release seat and the bayonet of the quick-release plate, or by locking the inclined surface of the quick-release plate through the plate buckle structure, thereby completing the plug-in installation of the quick-release plate and the quick-release seat. Since the existing quick-release plate and quick-release seat are relatively cumbersome to operate during the clamping and unlocking process, the disassembly and assembly efficiency is low, and the quick-release plate and the quick-release seat are still not firmly connected or loose, resulting in the problem of poor stability of the connection method between the quick-release plate and the quick-release seat, which makes it difficult to disassemble and replace, seriously affecting the efficiency and user experience of the assembly connection.

[0072] The specific installation and use process of this embodiment is as follows: the quick-release plate is detachably clamped and installed on the base 201 through the limiting portion 103, and the clamping protrusion 203 on the base 201 and the locking protrusion 208 of the locking block 207 are combined to form a fast and stable connection method;

[0073] Specifically, pressure is applied to the unlocking member 205, and the unlocking member 205 drives the locking block 207 to move along the sliding cavity 204. The wedging surface 210 of the wedging block 206 is loosened from the locking block 207 and the unlocking member 205, and moves into the sliding groove 227 under the action of the fourth resetting member 216. When the locking block 207 is compressed by the third resetting member 215 and moves away from the holding protrusion 203, the self-locking member 212 enters the unlocking groove 2221 under the resetting action of the first resetting member 213, and the self-locking member The top end of 212 is kept exposed on the upper surface of the base 201 by the first return member 213, and the unlocking groove 2221 of the locking block 207 is clamped by the unlocking portion 223 to prevent it from being accidentally clamped. At this time, the unlocking member 205 can be loosened to restore the unlocking member 205 to its original position under the action of the second return spring, that is, part of the unlocking member 205 is exposed outside the base 201, so that the locking protrusion 208 of the locking block 207 and the clamping protrusion 203 form an open unlocking state, and the base 201 is unlocked;

[0074] When the quick-release plate is inserted into the base 201, the self-locking member 212 is compressed by the plate body 101 into the sliding cavity 204, so that the unlocking portion 223 of the self-locking member 212 releases the clamping of the unlocking groove 2221 of the locking block 207, so that the locking block 207, under the reset action of the third reset member 215, causes the locking protrusion 208 and the clamping protrusion 203 to quickly clamp and lock the plate body 101, and the self-locking groove of the locking block 207 slides into the self-locking portion 224 of the self-locking member 212 and clamps the self-locking member 212 to prevent its top from being exposed on the upper surface of the base 201 At the same time, under the clamping action of the locking block 207, the wedge block 206 is reset through the fourth reset piece 216, thereby driving the wedging surface 210 of the wedge block 206 to contact the control part 225 of the unlocking piece 205 and the contact part 226 of the locking block 207 to form a wedge-tight fit, so that when no pressure is applied to the unlocking piece 205, the wedging surface 210 of the wedge block 206 can firmly wedge the unlocking piece 205 and the locking block 207, thereby reducing the loosening and shaking of the locking block 207, thereby improving the stability and reliability of use, and completing the locking of the plate body 101.

[0075] In summary, the combination of the self-locking part 212 and the unlocking part 205 realizes the quick self-locking function of the quick-release assembly, which greatly improves the convenience and safety of use. The quick disassembly of the quick-release plate simplifies the disassembly process and improves the operating efficiency. At the same time, the wedging surface 210 of the wedging block 206 cooperates closely with the locking block 207 and the unlocking part 205 to form a stable wedging effect, ensuring that the quick-release plate is not easy to loosen or fall off when subjected to external force, thereby improving the stability and reliability of the connection and enhancing the quick-release efficiency.

Specifically, the wedge block 206 is screwed in, so that its wedge surface 210 contacts the control part 225 of the unlocking member 205 and the contact part 226 of the locking block 207 to form a wedge-tight fit. When it is unlocked, the wedge block 206 is rotated toward the rotation groove 231 by the rotation of the rotating shaft 233, thereby improving the stability and reliability of the wedge block 206.
