Description

Technical Field

[0001] This utility model relates to the field of film and television equipment, and in particular to an optical accessory unlocking component. Background Technology

[0002] In film and television production, optical accessories such as lampshades and softboxes often need to be used with film and television lights. Traditionally, when connecting the light body to the optical accessory, a connector is typically installed on the light body. A locking mechanism, such as a bayonet, is incorporated into the connector, and the optical accessory has elastic clips on its outer periphery. These clips engage with the connector to achieve a stable connection. However, due to the structural limitations of the connector and the optical accessory, the space available for finger or tool operation during unlocking can be very limited. This makes it difficult for users to apply force and accurately press or flick the elastic clips, increasing the difficulty and complexity of unlocking and causing inconvenience to users.

[0014] Furthermore, the locking part is a bayonet provided on the connecting seat, and the locking end is provided with a locking connector. When the linkage end moves, the locking connector extends into or retracts from the bayonet.

[0015] One end of the elastic component abuts against the end of the snap-fit ​​connector opposite to the snap-fit ​​opening, and the other end of the elastic component is connected to the connecting seat and is used to provide an elastic stress to drive the snap-fit ​​connector to extend into the snap-fit ​​opening.

[0017] Furthermore, the linkage end is provided with a third limiting groove, and the connecting seat is provided with a second limiting member. The second limiting member passes through the third limiting groove and abuts against the groove wall of the third limiting groove when the linkage end moves.

[0018] Furthermore, the locking end has a through cavity, one end of the elastic member passes through the through cavity, and the other end of the elastic member is connected to the second limiting member.

[0019] Furthermore, the linkage end is also provided with a snap-fit ​​notch, and the driving end snaps into the snap-fit ​​notch; the inner wall of the snap-fit ​​notch has an arc-shaped guide surface, and the arc-shaped guide surface slides in cooperation with the outer peripheral wall of the driving end when the driving end rotates, so as to guide the movement of the linkage end.

[0020] Furthermore, the outer diameter of the linkage end is larger than the outer diameter of the locking end, and when the locking connector extends into the bayonet slot, it abuts against the end wall of the bayonet slot.

[0021] Furthermore, the connecting seat has a first side and a second side that are opposite to each other, the locking part is provided on the first side, and the locking mechanism is provided on the second side.

[0022] In summary, the optical accessory unlocking component provided by this utility model has the following technical effects: when unlocking is required, only an external force needs to be applied to the force-bearing end of the unlocking component to make the driving end rotate, thereby moving the linkage end of the locking component and driving the locking end of the locking component away from the locking part. At this time, the locking part can be unlocked. The entire unlocking process does not require finger or tool operation in a narrow space, allowing users to complete the unlocking operation more easily. Attached Figure Description

[0037] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0038] See Figure 1 and Figure 6This utility model discloses an optical accessory unlocking assembly, including: a connecting base 10 and a locking mechanism, wherein a locking part 11 is provided on the connecting base 10. The locking mechanism is installed on the connecting base 10, and specifically the locking mechanism includes a locking member 20, an unlocking member 30 and an elastic member 40. The locking member 20 has a linkage end 21 and a locking end 22. When the linkage end 21 is subjected to force, the locking end 22 moves closer to or away from the locking part 11. The unlocking member 30 is connected to the connecting base 10 and is rotatably connected to the connecting base 10. The unlocking member 30 has a driving end and a force-receiving end. The driving end is connected to the linkage end 21 and rotates when the force-receiving end is subjected to force, thereby linkageing the movement of the linkage end 21 of the locking member 20. The elastic member 40 is connected to the locking end 22 and is used to drive the locking end 22 to move closer to the locking part 11.

[0039] Based on the above structure, during assembly, the two ends of the elastic component 40 (such as a spring, elastic rubber, or elastic sheet) can be connected to the connecting seat 10 and the locking end 22 on the locking component 20, respectively. When the locking mechanism is in the initial state, the elastic component 40 is in a naturally unfolded state, which will generate an elastic stress that restores its initial shape. This elastic stress acts on the locking end 22, driving the locking end 22 to move along a straight trajectory toward the locking part 11. When the locking end 22 approaches the locking part 11 and cooperates with it, a stable locking force is generated to lock the optical accessory on the connecting seat 10.

[0040] When unlocking is required, an external force is applied to the force-bearing end of the unlocking member 30 in the direction of the locking part 11. Since the unlocking member 30 is rotatably connected to the connecting seat 10 to form a lever structure, when the force-bearing end is subjected to force, it will rotate along an arc trajectory towards the locking part 11 with the connection point rotatably connected to the connecting seat 10 as the center. At the same time, it will drive the drive end connected to it to rotate along an arc trajectory in the opposite direction away from the locking part 11 with the same center.

[0041] Simultaneously, since the driving end is connected to the linkage end 21, it can move together with the linkage end 21 of the locking member 20 away from the locking part 11 during rotation. During this process, the locking end 22 located at the other end of the linkage end 21 can also be smoothly moved away from the locking part 11, at which point the optical accessory can be detached from the connecting seat 10. During this process, since the elastic member 40 is stretched and storing elastic potential energy, when the external force is removed, the elastic member 40 releases the elastic potential energy, provides stress, and pulls the locking end 22 to rotate in the opposite direction, causing it to move closer to the locking part 11 again.

[0042] Therefore, when using the optical accessory unlocking component in this embodiment, during unlocking, only an external force needs to be applied to the force-receiving end of the unlocking lever to move the linkage end 21 of the locking member 20, thereby driving the locking end 22 away from the locking part 11 to achieve unlocking. The entire unlocking process does not require finger or tool operation in a confined space, allowing users to complete the unlocking operation more easily.

[0043] It should be noted that the locking part 11 in this embodiment can be a slot, bayonet or other structure provided on the connecting seat 10, while the locking end 22 is a block or buckle provided on the locking member 20 that cooperates with the slot of the connecting seat 10. When the connecting structure on the optical accessory is installed into the slot, the block can extend into the slot under the drive of the elastic member 40 to achieve locking.

[0044] Alternatively, the unlocking component 30 can be composed of a rod, with the end of the rod away from the locking component 20 being the force-bearing end for applying external force; the end of the rod near the locking component 20 is the driving end, which is connected to the linkage end 21 of the locking component 20. A pivot mounting hole is provided in the middle of the rod for mounting with the pivot on the connecting seat 10, so as to utilize the lever principle to generate a large displacement at the driving end with a small external force, thereby effectively driving the locking component 20 to move and unlock. Of course, the unlocking component 30 can also be a linkage structure formed by hinged two or more rods, with one rod being the force-bearing end and the other rod being the driving end, which can also achieve the above effect.

[0045] Furthermore, the unlocking component 30 includes a force-receiving section 31, a driving section 32, and a connecting section 33. The driving section 32 is set at an angle to the force-receiving section 31 and is connected by the connecting section 33. The connecting section 33 is rotatably connected to the connecting seat 10. The driving end is located in the driving section 32, and the force-receiving end is located in the force-receiving section 31.

[0046] Based on this structure, during installation, a through hole can be provided on the connecting section 33 and a corresponding rotating shaft can be provided on the connecting seat 10, so that the connecting section 33 is rotatably connected to the connecting seat 10 via the rotating shaft, so that when the force-bearing section 31 is subjected to force, the connection between the connecting section 33 and the connecting seat 10 (such as the rotating shaft) rotates around the center, so as to synchronously drive the driving section 32 to rotate in the opposite direction.

[0047] Meanwhile, since the force-bearing section 31 and the drive section 32 are set at an angle, the layout can be optimized according to the actual space during assembly, making more efficient use of space and making the unlocking mechanism more compact. Furthermore, when force is applied to the force-bearing section 31, the angle results in a longer distance (i.e., lever arm) from the drive section 32 to the rotating shaft compared to when the drive section 32 and force-bearing section 31 are parallel. This means the lever arm of the drive section 32 is greater than that when they are parallel. Therefore, under the same resistance, a smaller force can be used to unlock, achieving a labor-saving effect and improving unlocking efficiency and convenience.

[0048] Furthermore, the angled arrangement provides better structural stability. When subjected to external forces, the angled structure can distribute the force to the driving section 32 and the force-bearing section 31. Through the stability principle of triangles, the entire structure becomes more stable and less prone to deformation or swaying. In contrast, parallel-connected structures may be more prone to instability when subjected to lateral or asymmetrical forces.

[0049] Furthermore, the unlocking component 30 also includes a button 34, one end of which is connected to the force-bearing end, and the other end of which protrudes from the edge of the connecting seat 10. When the button 34 is subjected to force, it moves along its own axis (i.e., the length direction of the button) to drive the force-bearing section 31 to rotate.

[0050] Specifically, button 34 protrudes from the edge of connector 10 so that the user can directly contact button 34. In this way, when unlocking is required, the user can simply press or push button 34 to make button 34 move along its own axis, thereby driving the force-bearing section 31 to rotate and unlock, without the need for additional tools or complicated operations, thus improving the unlocking efficiency.

[0051] It should be noted that during assembly, a mounting groove or hole matching the shape of the button 34 can be provided on the connecting seat 10, and a part of the button 34 can be embedded therein, which can effectively limit the movement of the button 34 in the non-axial direction, while the other end of the button 34 is connected to the force-bearing end through a connector (such as a pin or a rotating shaft).

[0052] Furthermore, the connecting seat 10 is provided with a first limiting member 12, and the button 34 is provided with a first limiting groove 341. The first limiting member 12 passes through the first limiting groove 341 and abuts against the groove wall of the first limiting groove 341 when the button 34 moves along its own axial direction.

[0053] Specifically, since the first limiting member 12 passes through the first limiting groove 341, when the button 34 is subjected to external force, the first limiting member 12 will contact the groove wall of the first limiting groove 341. The groove wall will prevent the first limiting member 12 from moving in the direction perpendicular to the groove wall, thereby limiting the displacement of the button 34 in that direction. At the same time, as long as the first limiting member 12 remains within the first limiting groove 341, the button 34 can only move along the extension direction of the first limiting groove 341, that is, the axial direction of the button 34, thus realizing the guiding function and ensuring that the button 34 can only move along a predetermined trajectory, improving the accuracy and reliability of the unlocking operation.

[0054] It should be noted that the first limiting member 12 in this embodiment can be a columnar structure, such as a limiting post or a limiting rod, provided on the connecting seat, or a block-shaped structure, such as a limiting block, a locking block, or a boss, provided on the connecting seat. A matching groove is provided on the button to cooperate with the first limiting member for limiting.

[0055] Furthermore, the connecting seat 10 is provided with a second limiting groove 13 and a pressing notch 14. The pressing notch 14 is located around the periphery of the connecting seat 10 and communicates with the second limiting groove 13. The button 34 passes through the pressing notch 14 and is inserted into the second limiting groove 13, and slides in cooperation with the inner wall of the second limiting groove 13 when force is applied.

[0056] Based on this structure, the pressing notch 14 is set around the connecting seat 10 and communicates with the second limiting groove 13, so that the button 34 can easily pass into the second limiting groove 13 through the pressing notch 14, providing a convenient channel for the installation of the button 34, thereby reducing the installation difficulty and improving the assembly efficiency. In addition, during the installation process, the second limiting groove 13 can also position the button 34, so that the button 34 is installed in the correct position.

[0057] In addition, after the button 34 is inserted into the second limiting groove 13, the groove wall of the second limiting groove 13 plays a further limiting role on the button 34, preventing the button 34 from shaking or displacing in the non-axial direction, making the movement of the button 34 more stable, thereby enhancing the structural stability and reliability of the entire unlocking mechanism.

[0058] Furthermore, when the button 34 is subjected to force, the outer peripheral wall of the button 34 slides and engages with the groove wall of the second limiting groove 13, making the button 34 move more smoothly along its own axis and less prone to jamming, thereby reducing the force required for user operation and making it more effortless.

[0059] Furthermore, the locking part 11 is a bayonet provided on the connecting seat 10, and the locking end 22 is provided with a locking connector 222. When the linkage end 21 moves, the locking connector 222 extends into or retracts from the bayonet; one end of the elastic member 40 abuts against the end of the locking connector 222 away from the bayonet, and the other end of the elastic member 40 is connected to the connecting seat 10 and is used to provide an elastic stress to drive the locking connector 222 to extend into the bayonet.

[0060] Based on this structure, in this embodiment, the locking part 11 is a bayonet set on the connecting seat 10. At the same time, a snap-fit ​​connector 222 matching the shape of the bayonet is provided on the locking section. Thus, when the linkage end 21 moves, it can drive the snap-fit ​​connector 222 to extend into or retract from the bayonet, thereby unlocking or locking. This structure of the bayonet and snap-fit ​​connector 222 is relatively intuitive and easy to align and fit during installation, which facilitates installation and debugging.

[0061] Moreover, since the elastic stress provided by the elastic component 40 drives the locking connector 222 to extend into the bayonet, after unlocking, as long as the linkage end 21 no longer applies external force, the locking connector 222 will automatically reset under the action of the elastic force and re-extend into the bayonet, realizing automatic locking without the need for additional operation by the user, thus improving the convenience of use.

[0062] More specifically, the snap-fit ​​connector 222 has a guide ramp that slides into the end wall of the snap-fit. Thus, during the process of the snap-fit ​​connector 222 extending into or retracting from the snap-fit, the sliding engagement between the guide ramp and the end wall of the snap-fit ​​reduces the friction and resistance between the snap-fit ​​connector 222 and the end wall of the snap-fit, making the movement of the snap-fit ​​connector 222 smoother.

[0063] Furthermore, the linkage end 21 is provided with a third limiting groove 211, and the connecting seat 10 is provided with a second limiting member 15. The second limiting member 15 passes through the third limiting groove 211 and abuts against the groove wall of the third limiting groove 211 when the linkage end 21 moves.

[0064] Specifically, by setting a second limiting member 15 on the connecting seat 10 and inserting it into the third limiting groove 211, the locking member 20 is connected to the connecting seat 10. Thus, when the linkage end 21 moves, the second limiting member 15, inserted into the third limiting groove 211, slides within the groove as the linkage end 21 moves. When the second limiting member 15 slides to abut against the groove wall of the third limiting groove 211, it prevents the linkage end 21 from continuing to move in that direction, thereby controlling the movement of the linkage end 21 and ensuring it can only move within a predetermined trajectory and range, preventing excessive movement or deviation, and thus improving the stability of the entire mechanism's operation.

[0065] More specifically, the locking end 22 has a through-hole 221. During assembly, one end of the elastic member 40 is inserted into the through-hole 221, and the other end of the elastic member 40 is connected to the second limiting member 15. The through-hole 221 provides positioning for the elastic member 40, allowing one end to be mounted on the locking end 22, thus improving the positional stability of the elastic member 40 in the mechanism. Simultaneously, the connection with the second limiting member 15 is also relatively stable, ensuring that the elastic member 40 can function stably during operation and will not affect the performance of the entire mechanism due to shaking or displacement.

[0066] It should be noted that the second limiting member in this embodiment can also be a columnar structure, such as a limiting post or a limiting rod, set on the connecting seat, or a block-shaped structure, such as a limiting block, a locking block, or a boss, set on the connecting seat. A matching groove is set on the linkage end to cooperate with the second limiting member for limiting.

[0067] Furthermore, the linkage end 21 is also provided with a snap-fit ​​notch 212, and the drive end snaps into the snap-fit ​​notch 212; the inner wall of the snap-fit ​​notch 212 has an arc-shaped guide surface 2121, and the arc-shaped guide surface 2121 slides with the outer peripheral wall of the drive end when the drive end rotates, so as to guide the movement of the linkage end 21.

[0068] Specifically, during assembly, the driving end (i.e., driving segment 32) and the linkage end 21 are engaged through the snap-fit ​​notch 212, forming a connection between them. This allows the driving end to effectively transmit force to the linkage end 21 when it rotates, causing the linkage end 21 to move synchronously. Simultaneously, because the inner wall of the snap-fit ​​notch 212 has an arc-shaped guide surface 2121, when the driving end rotates around the axis, its outer peripheral wall can slide against the arc-shaped guide surface 2121, converting the circular motion of the driving end into the linear or curvilinear motion of the linkage end 21, thus achieving a change in the direction of force. For example, when the driving end rotates downwards, the arc-shaped guide surface 2121 guides the linkage end 21 away from the locking part 11, thereby unlocking it.

[0069] More specifically, the arc-shaped guide surface 2121 allows for a smooth transition between the drive end and the linkage end 21 during rotation, preventing uneven movement caused by abrupt changes or jamming, thus making the unlocking process smoother. Simultaneously, it reduces wear between components, indirectly extending the structure's service life.

[0070] It should be noted that the above effect can also be achieved by setting the arc guide surface 2121 at the drive end.

[0071] In addition, in this embodiment, the outer diameter of the linkage end 21 is larger than the outer diameter of the locking end 22, and when the locking connector 222 extends into the bayonet, it abuts against the end wall of the bayonet. In this way, when the locking connector 222 extends into the bayonet and reaches the appropriate position, the restriction of the end wall of the linkage end 21 can prevent the locking connector 222 from extending too far, which may cause the locking connector 222 to interfere with other components, affect the normal operation of the device, and improve the reliability and stability of the locking process.

[0072] Furthermore, the connecting seat 10 has a first side and a second side that are opposite to each other, the locking part 11 is provided on the first side, and the locking member 20 is provided on the second side.

[0073] Specifically, by placing the locking part 11 and the locking mechanism on opposite sides, the locking part 11 and the locking mechanism are relatively independent, allowing operators to more easily operate the components on both sides separately during operation and maintenance. For example, when the locking part 11 needs to be repaired or replaced, it will not be obstructed by the locking part 20, and vice versa, improving the convenience of operation and the efficiency of maintenance.

[0074] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
