For example, corresponding connecting components are used in the connection between two devices or components such as photographic devices, photographic brackets, and display brackets. In order 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 bracket, the functional device is set on the photographic bracket through the connecting component, thereby completing the installation and connection of the photographic bracket and related equipment.

[0003] On July 14, 2023, the applicant filed an invention patent application with the patent publication number CN 117119720 A. The patent discloses a quick-release plate structure that can automatically lock and is compatible with general-specification photographic devices, including a self-locking Arca quick-release plate body, the self-locking Arca quick-release plate body is provided with a self-locking assembly, the top of the self-locking Arca quick-release plate body is provided with a card slot, the self-locking Arca quick-release plate is detachably restrained in the card slot, and the bottom of the self-locking Arca quick-release plate body is connected to the Arca standard base plate via a bottom adapter plate and a first screw. This patent mainly solves the problem that a photographic device can automatically lock by directly installing the self-locking Arca quick-release plate into the card slot, thereby improving the efficiency of use, and improving the compatibility and extensibility of the quick-release plate connection and installation, effectively reducing the user's usage cost.

[0004] However, the connecting components of this patent still have certain defects. The overall components in this patent are numerous and the connection structure is complex, which is not conducive to rapid connection and use during the production and assembly process. When an abnormality occurs, the connection structure of the device is complex and cumbersome, making it difficult to disassemble and replace, affecting the user experience and production efficiency.

[0005] Chinese patent publication number CN 117489928 A discloses a quick-release assembly, photographic accessory, and assembly and disassembly kit. The quick-release assembly includes a connecting base with a fitting slot that allows it to be fitted onto a structural member, the structural member having a latching slot. The connecting base is provided with an actuating structure, a reset member, and a retaining member. The retaining member is exposed from the inner wall of the fitting slot and fits into the latching slot. The actuating structure is movably mounted on the connecting base, and the reset member applies a force to reset the actuating structure. The quick-release assembly has a locked state and an unlocked state. In the unlocked state, the actuating structure releases the retaining member, disengaging it from the latching slot. In the locked state, the actuating structure resets and squeezes the retaining member, retaining it in the latching slot. The quick-release assembly of this patent allows for tight connections between components of photographic equipment, facilitates connection and installation, and helps enhance the user experience.

[0006] However, the quick-release assembly of this patent still has certain defects. In this patent, the enabling structure can control the locking of the structural member by the card holder, and the self-locking locking of the card holder requires the enabling structure to drive the extrusion member to complete the extrusion of the card holder, thereby locking the card slot. The connection control structure of the card holder is relatively cumbersome, and the card holder may be loose or not firmly connected. The traditional connection method between the photographic device and the bracket often has problems such as complicated operation, slow connection speed, and poor stability, which makes it difficult to disassemble and replace, seriously affecting the efficiency and user experience of the equipment assembly connection.

The reset member 120 can apply a force to the control member 110 to reset it;

[0035] The connection between the control member 110 and the wedge block 130 has a locked state and an unlocked state. In the locked state, the connecting seat 100 moves along the sliding portion 201 of the structural member 200 to the self-locking inclined surface 202, and the reset member 120 generates a reset to squeeze the wedge block 130, so that the wedge block 130 is wedged between the clamping inclined surface 102 of the connecting seat 100 and the self-locking inclined surface 202 of the sliding portion 201; in the unlocked state, the control member 110 squeezes the reset member 120, so that the locked wedge block 130 slides and loosens along the clamping inclined surface 102 of the connecting seat 100 and the self-locking inclined surface 202 of the sliding portion 201.

[0036] This embodiment is applied to photographic equipment to achieve connection between photographic equipment (photographic accessories). Two components (hereinafter referred to as the first component and the second component) in the photographic equipment can be connected through a connecting base 100 and a structural member 200. The first component is connected to the connecting base 100 by screw connection, riveting, or snap connection. As shown in FIG3 , the connecting base 100 is provided with a threaded hole that communicates with the sleeve groove 101. The threaded hole is threadedly connected to a connecting bolt.

[0038] Optionally, a portion of the first component may be configured as a connection socket 100 as needed, so that the first component directly has the function of the connection socket 100 and can be quickly connected to the structural component 200 .

[0039] Optionally, a portion of the second device may be configured as a structural member 200 as needed, so that the second device directly carries the function of the structural member 200 and can be quickly connected to the connecting socket 100 .

[0040] The fitting groove 101 on the connecting seat 100 can be located on one side thereof, and the fitting groove 101 is adapted to the structural member 200. When the connecting seat 100 is fitted on the structural member 200, the structural member 200 passes through the notch at one end of the fitting groove 101 and passes through the notch at the other end, thereby being able to slide along the sliding portion 201. When it moves to the self-locking inclined surface 202 on the surface of the sliding portion 201, the wedging block 130 forms a wedging clamp with the self-locking inclined surface 202 and the clamping inclined surface 102, and can be unlocked by pressing the control member 110, so that it can continue to move along the sliding portion 201.

[0041] In some embodiments, two wedge blocks 130 are provided. In this embodiment, two wedge blocks 130 are provided and are relatively distributed in the sleeve groove 101 of the connecting seat 100 , and guide pillars 132 are formed on the opposite inner sides of the two wedge blocks 130 .

[0042] In this embodiment, a mounting cavity 103 is provided on the connecting seat 100, and the inserting portion 111 of the control member 110 can be slidably inserted into the mounting cavity 103, and one end of the control member 110 is exposed on the outer side surface of the connecting seat 100 to form a pressable protrusion. The control member 110 can make the wedge block 130 cooperate with it through the sliding structure. The control member 110 is connected to the mounting cavity 103 through the inserting portion 111. The wedge block 130 is located on the sliding path of the control member 110. The control member 110 is used to squeeze or release the wedge block 130 through the inserting portion 111, so that the pressing or releasing of the control member 110 can control the clamping and loosening of the wedge block 130, and the structural member 200 can be unlocked or locked.

[0043] Optionally, the reset member 120 is provided according to actual needs. In this embodiment, the reset member 120 is a spring and two reset members 120 are provided. The inner wall of the installation cavity 103 is formed with a mounting groove 104 for mounting the reset member 120. One end of the reset member 120 abuts against the mounting groove 104, and the other end of the reset member 120 abuts against the end surface of the insertion portion 111 on the control member 110 extending toward the installation cavity 103.

[0044] Optionally, the two reset members 120 are respectively sleeved with the guide posts 132 between the two wedging blocks 130, so that they are located between the two wedging blocks 130, so that the two ends of the reset member 120 are respectively abutted against the guide posts 132 of one wedging block 130, and the reset and expansion of the reset member 120 can drive the two wedging blocks 130 to expand, so that the exposed parts of the wedging blocks 130 are in contact with the self-locking inclined surface 202 and the clamping inclined surface 102 and wedged, thereby generating a locked state for the structural member 200, and conversely, the compression of the reset member 120 can drive the two wedging blocks 130.

[0045] In some embodiments, a pressure plate 105 is connected to the fitting groove 101 of the connecting seat 100, and an avoidance groove 106 for matching the wedge block 130 is opened on the pressure plate 105. The pressure plate 105 is installed on the bottom of the fitting groove 101 by screws. Guide slopes are formed on opposite sides of the pressure plate 105. When the pressure plate 105 is installed on the fitting groove 101, a self-locking channel is formed between the guide slope and the clamping slope 102, and the wedge block 130 is located between the clamping slope 102 and the guide slope of the fitting groove 101.

[0046] In some embodiments, the structural member 200 can slide relative to the fitting groove 101 of the connecting seat 100 through the sliding portion 201. When the control member 110 is in the locked state, the fitting portion wedges and presses the structural member 200 through the wedging block 130. When the control member 110 is in the unlocked state, the fitting portion releases the structural member 200 through the wedging block 130. The width of the self-locking inclined surface 202 on the sliding portion 201 is adapted to the expanded self-locking width of the wedging block 130.

[0047] In some embodiments, the clamping bevel 102 of the connecting seat 100 and the self-locking bevel 202 of the structural member 200 can be set as an arc surface, an inclined surface or a wavy surface, and the contact surface between the wedge block 130 and the clamping bevel 102 and the self-locking bevel 202 can be set as a square, a column or a spherical shape.

[0048] In this embodiment, the sliding structure is composed of an insertion groove 112 formed on the insertion part 111, and a pin 131 is provided on the wedge block 130. The insertion groove 112 of the insertion part 111 is inserted into the pin 131 on the wedge block 130. The insertion part 111 extends into the installation cavity 103, which can drive the pin 131 on the wedge block 130 to slide along the insertion groove 112 of the insertion part 111. The sliding direction of the pin 131 is set at an angle to the sliding direction of the insertion part 111 in the control member 110. The pairing of the insertion groove 112 formed on the insertion part 111 and the pin 131 enables the insertion groove 112 to drive the wedge block 130 to unlock or lock the self-locking inclined surface 202 of the structural member 200 when the control member 110 is pressed or released.

[0049] When the control member 110 is pressed by an external force, the insertion portion 111 of the control member 110 slides along the installation cavity 103, and the position of the insertion slot 112 changes accordingly, so that the pin 131 inserted in the insertion slot 112 is pushed by the side wall of the insertion slot 112 and slides along the path of the insertion slot 112, thereby driving the wedge block 130 to move.

[0050] In some embodiments, the insertion portion 111 and the control member 110 are integrally formed, and a relative insertion slot 112 is set on the insertion portion 111 of the control member 110. The pins 131 on the wedge block 130 are set corresponding to the insertion slots 112 on the insertion portion 111. Each pin 131 is correspondingly plugged into an insertion slot 112, which is set according to actual conditions. The number of groups of insertion slots 112 and pins 131 can be set to one group or multiple groups according to actual conditions.

[0051] In this embodiment, the connection base 100 forms a wedge-tight fit with the two self-locking inclined surfaces 202 on the structural member 200 through the two wedge blocks 130 provided thereon, thereby improving the connection stability and operability between the two, thereby further enhancing the tightness of the connection between the two components of the photographic equipment. In addition, as another embodiment, optionally, while a structure is provided at the slot end of the connection base 100 near the fitting slot 101 to prevent the structural member 200 from sliding out, only one wedge block 130 can be provided at the corresponding other end to wedge between the clamping inclined surface 102 of the connection base 100 and the self-locking inclined surface 202 of the sliding portion 201 to form a self-locking connection.

[0052] The specific use of this embodiment: the combined use of the control member 110, the reset member 120 and the wedge block 130 allows the connection state of the connecting seat 100 and the structural member 200 to be flexibly switched. In the unlocked state, by squeezing or pressing the end of the control member 110 exposed on the outer side of the connecting seat, the two wedge blocks 130 are clamped and slid loose between the clamping inclined surface 102 of the connecting seat 100 and the self-locking inclined surface 202 of the sliding portion 201. The reset member 120 under squeezing generates compression, so that the structural member 200 can be easily removed from the connecting seat. 100, and in the locked state, release the control member 110, so that the reset member 120 is reset and expanded to form an extrusion effect, so that the two wedge blocks 130 are tightly wedged between the clamping slope 102 of the connecting seat 100 and the self-locking slope 202 of the sliding part 201, ensuring the firmness and stability of the connection, and not easily loosened or falling off due to external force, thereby improving the durability and reliability of the component, improving the efficiency and user experience of the connection of the photographic device, and can be adapted to other equipment and scenarios that require quick connection and disassembly.
