Description

[Technical Field]

[0001] This utility model relates to the field of softbox technology, and in particular to a softbox chuck structure and a softbox. [Background Technology]

[0002] Softboxes, as common photographic accessories, are frequently used not only in professional portrait photography but also in commercial advertising and still life photography. The main structure and function of a softbox is to reflect light through the highly reflective material on its inner walls, then diffuse it through one or more layers of diffuser fabric, creating a soft and delicate lighting effect. Softboxes come in various sizes and shapes, such as square, rectangular, rectangular, and octagonal.

[0003] Softboxes typically consist of a chuck assembly and multiple support rods connected to the chuck assembly. The softbox unfolds by extending the support rods or folds them back into place. However, existing softboxes have complex unfolding and folding mechanisms, making it impossible to switch between unfolded and folded states quickly or even in a single step. Furthermore, when the support rods are not installed, the chuck cannot be fully folded, resulting in a larger packaging volume.

[0004] To address the above issues, we have provided a new technical solution. [Utility Model Content]

[0043] This utility model provides a softbox chuck structure, as shown in the embodiments, such as... Figures 1 to 10 As shown, including

[0044] 10 ring chucks;

[0045] Adapter 20 is connected to the top of the annular chuck 10;

[0046] Multiple support seats 30 are circumferentially distributed on the annular chuck 10; the annular chuck 10 has multiple through grooves 11 on its lower surface, and the multiple support seats 30 are respectively arranged in the multiple through grooves 11, and each support seat 30 is movably connected to the annular chuck 10.

[0047] Multiple locking units are circumferentially distributed on the annular chuck 10 and correspond one-to-one with each support seat 30; the locking units have a locked state and an unlocked state. In the locked state, the support seat 30 is unfolded relative to the annular chuck 10. In the unlocked state, the support seat 30 is flipped under the annular chuck 10 through the through groove 11.

[0048] The unlocking unit has a ring or semi-ring structure. Driven by an external force, it rotates synchronously with multiple locking units to switch the locking units to the unlocked state.

[0049] In this utility model, the support base 30 is in the unfolded state (e.g. Figures 1 to 6 As shown), multiple support seats 30 are locked and limited within the through groove 11 by their respective locking units; when it is necessary to switch to the storage state, an external force drives the unlocking unit to rotate. During rotation, the unlocking unit synchronously links with multiple locking units, causing them to switch to the unlocked state, releasing the locking and limiting of the support seats 30. After the support seats 30 are no longer limited, they automatically flip downwards under the influence of gravity to below the annular chuck 10 (as shown). Figures 7 to 10 (As shown); When it is necessary to return to the unfolded state, the unlocking unit is rotated again by external force, which unlocks the locking unit again. The annular chuck 10 is flipped, causing the support base 30 to fall back into the through groove 11 and extend. The external force driving the unlocking unit is released, the locking unit resets, and the support base 30 is locked and limited in the through groove 11 again. This utility model can unlock multiple locking units at once through the unlocking unit, simultaneously switching multiple locking units to the unlocked state, and causing multiple support bases 30 to quickly flip under the annular chuck 10. One operation, multiple linkages, and rapid unlocking.

[0050] Furthermore, in some embodiments of this utility model application, such as Figure 3 , 4 As shown in Figures 5, 6, 9, and 10, the locking unit has a locking part 40. In the locked state, the locking part 40 elastically abuts against the support base 30, locking the support base 30 within the through groove 11. A dial 41 extends upward from the top of the locking part 40. The dial 41 can be linked with the unlocking unit. Under the drive of the unlocking unit, the locking part 40 is moved backward in the opposite direction of the elastic abutment to release the locking limitation on the support base 30. In this way, the support base 30 will automatically flip downward under the annular chuck 10 under the action of gravity, realizing the switch of the support base 30 from the unfolded state to the stored state.

[0051] Specifically, in the embodiments, such as Figure 3 , 4 As shown in Figures 5, 6, 9, and 10, the unlocking unit includes an elastic pull-limiting part and a rotating body. The rotating body has a pushing part 81 corresponding to the dial 41 of each locking unit. Under normal conditions, the elastic pull-limiting part pulls the rotating body so that the pushing part 81 and the dial 41 are in a non-contact state, and there is a certain distance between the pushing part 81 and the dial 41. The rotating body rotates under the drive of external force so that each pushing part 81 on it contacts each dial 41 and pushes the dial 41 backward in the opposite direction of the elastic abutment of the locking part 40 until the support seat 30 is completely released from the locking limit. In this way, the support seat 30 loses the limit and automatically flips downward under the action of gravity to the bottom of the annular chuck 10, realizing the switch of the support seat 30 from the unfolded state to the stored state.

[0052] Specifically, in the embodiments, such as Figure 3 , 4 As shown in Figures 5, 6, 9, and 10, the rotating body includes a pair of symmetrically arranged semi-ring bodies 80, each semi-ring body 80 having a head end and a tail end; all pushing parts 81 are distributed on the pair of semi-ring bodies 80, and each semi-ring body 80 is provided with a pushing part 81. In the embodiment, the semi-ring body 80 is disposed on the upper part of the annular chuck 10, and the locking unit is disposed on the lower part of the annular chuck 10. The pushing part 81 at the upper part has a corresponding locking unit at its lower part, so that the semi-ring body 80 and all the locking units on the same side below it have locking parts 4. 0 corresponds to linkage; the elastic pulling limit part is set between the tail ends of a pair of semi-rings 80 and elastically pulls the semi-rings 80 respectively. The semi-rings 80 have a limiting stroke. The semi-rings 80 can rotate within the limiting stroke towards the elastic pulling limit part, or rotate in the opposite direction so that all the pushing parts 81 on it push the dial 41 of all the locking parts 40 on that side to unlock the locking unit; the elastic pulling limit part is an elastic tension spring 90, and the two ends of the elastic tension spring 90 are respectively fixedly connected to the tail ends of a pair of semi-rings 80. The head end of the semi-rings 80 extends outward toward the outer side of the annular chuck 10 with a lever 82. The lever 82 can be driven by external force to rotate the semi-rings 80 to counteract the pulling force of the elastic pulling limit part.

[0053] Under normal conditions, the elastic spring 90 pulls the semi-ring 80 to maintain a tendency to move closer to the elastic spring 90 within the limit stroke. When unlocking is required, the lever 82 is moved to drive the semi-ring 80 to counteract the tension of the spring and rotate in the direction of the central axis between the two semi-rings 80 (i.e., in the opposite direction of the elastic pulling limit part). In this way, each pushing part 81 on the semi-ring 80 is pushed into contact with the dial 41 of the locking unit below it. As the semi-ring 80 rotates, the pushing part 81 continues to push the dial 41. The dial 41 drives the locking part 40 of the locking unit to move backward in the opposite direction of the elastic contact of the locking part 40 until the support seat 30 is completely released from the locking limit. In this way, the support seat 30 loses its limit and automatically flips downward under the action of gravity to the bottom of the annular chuck 10, realizing the switch of the support seat 30 from the unfolded state to the stored state. By turning the lever 82 once, the semi-ring 80 can be rotated, which will unlock all the locking units below the semi-ring 80. Alternatively, you can pinch the levers 82 of a pair of semi-rings 80 with your fingers and bring the two levers 82 together, so that the pair of semi-rings 80 can be rotated at the same time in the direction of the central axis between the two semi-rings 80, which will unlock all the locking units.

[0054] Furthermore, in some embodiments of this utility model application, such as Figure 4 , 5 As shown in Figures 9 and 10, a plurality of limiting slots 83 are provided on the semi-ring body 80, and the length of the limiting slots 83 is the limiting stroke. A plurality of limiting posts 12 are provided on the annular chuck 10. The limiting posts 12 are located inside the limiting slots 83 and normally abut against one side of the limiting slots 83. When the semi-ring body 80 rotates to unlock and lock the unit, it abuts against the other side of the limiting slots 83.

[0055] Furthermore, in some embodiments of this utility model application, such as Figure 5 , 6As shown in Figure 10, the locking unit includes a locking base 50 disposed within the annular chuck 10. A locking part 40 is disposed on the front side of the locking base 50, and an elastic pressing part is provided on the rear side of the locking base 50. The elastic pressing part acts on the locking part 40 and normally drives the locking part 40 to abut against the support base 30. The elastic pressing part consists of a spring 60 and an arc-shaped pressing fork 70 located at the upper end of the spring 60. The arc-shaped pressing fork 70 elastically presses against the support base 30. Under normal conditions, the spring 60 presses against the arc-shaped pressing fork 70, which in turn holds and presses against the locking part 40, causing the locking part 40 to elastically abut against the support base 30. When the pushing part 81 pushes the dial 41, the dial 41, along with the locking part 40, counteracts the elastic force of the spring 60 and retracts as a whole. When the support base 30 loses its elastic pressing force, it automatically flips downwards under the action of gravity. After the semi-ring 80 is released, the pushing part 81 moves away from the dial 41 and is in a non-contact state. The locking part 40 loses the force to counteract the elastic force of the spring 60 and resets again under the elastic force of the spring 60. However, at this time, the support base 30 has already flipped and fallen. The reset locking part 40 abuts against the top of the support base 30, locking the support base 30 and ensuring the stability of the support base 30 in the stored state.

[0056] Furthermore, in some embodiments of this utility model application, such as Figure 4 , 5As shown in Figures 11 and 12, in the unlocked state, the support base 30 can be flipped and folded onto the side of the annular chuck 10 away from the adapter 20. At this time, the support base 30 is in a folded state that fits against the bottom surface of the annular chuck 10, reducing the overall volume of the annular chuck 10 and making packaging more convenient and compact. Specifically, the annular chuck 10 has multiple folding grooves 14 for accommodating the support base 30 on the side away from the adapter 20; at least one support base 30 is placed in the central hole 13 in the middle of the annular chuck 10 when flipped and folded; a through groove 11 is provided on the inner wall of the central hole 13 of the annular chuck 10 for the support base 30 to pass through the window of the central hole 13; a window closing plate 100 is provided at the window; and an elastic protrusion 110 connected to the window closing plate 100 is provided on the inner wall of the central hole 13 of the annular chuck 10. The elastic protrusion 110 extends in the normal state to close the window with the window closing plate 100, and can retract the window closing plate 100 to expose the window when retracted. After the support base 30 is unlocked and flipped down, it can be flipped to the bottom surface of the annular chuck 10 (the side away from the adapter 20) and inserted into the folding groove 14. Since some support bases 30 cannot be correspondingly positioned in the folding groove 14 after flipping, some support bases 30 are placed in the central hole 13 of the annular chuck 10 after flipping. At this time, it is necessary to first elastically tighten the elastic protrusion 110, retract the window closing plate 100, expose the window, and then flip the support base 30 so that it extends into the central hole 13 of the annular chuck 10. At this time, the folding of all support bases 30 is achieved (e.g., Figure 11 , 12 (As shown).

[0057] This utility model also provides a softbox, including the softbox chuck structure described in any of the above claims, as well as a support rod and a softbox cloth.
