[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] See Figures 1-2A softbox includes a softbox chuck (hereinafter referred to as the chuck), a support rod 500 and a reflective cloth 600. The support rod 500 is mounted on the chuck, and the reflective cloth 600 is placed on the support rod 500. The reflective cloth 600 has an inner surface and an outer surface, and the inner surface is provided with a reflective layer that reflects light.

[0038] like Figures 2-5 This application also provides a softbox chuck (hereinafter referred to as the chuck), including a chuck base 100, an adapter 200, multiple connectors, and a locking element 400. The chuck base 100 has an annular structure, with an axial direction and corresponding radial and circumferential directions. The adapter 200 is rotatably mounted on the chuck base 100 and has the following characteristics: Figure 2 The unfolded state shown, and as Figure 4 The folded state shown.

[0039] The support rod 500 is connected to the connector, for example, one end of the support rod 500 is inserted and fixed to the connector. The connector includes multiple first connectors 310 and multiple second connectors 320, the number of second connectors 320 being less than half the total number of connectors. The number of first connectors 310 can be adaptively selected according to requirements; for example, in the figure, there are 6 first connectors 310, evenly arranged circumferentially, and 2 second connectors 320.

[0040] The first connector 310 is movably connected to the base 100, and the second connector 320 is connected to the adapter 200. In actual use: (e.g.) Figure 5 As shown, when the adapter 200 is in the folded state, each of the first connectors 310 moves under the pull of the reflective cloth 600 and faces the same side (as shown by the dotted and solid lines in the figure). The second connector 320 and each of the first connectors 310 face the same side, and the reflective cloth 600 overlaps, making the softbox flat and easy to store. When the adapter 200 is rotated to the unfolded state, the second connector 320 faces the opposite direction to the folded state, the reflective cloth 600 unfolds, and at the same time, the reflective cloth 600 pulls the first connectors 310 to move and finally arranges the second connectors 320 radially. The reflective cloth 600 is stretched open to form a cage-like cover, and light shines out from the cover opening. Auxiliary devices 700 such as soft cloth and grids can also be set at the cover opening.

[0041] The softbox chuck of this application has multiple second connectors that are rotatably connected to the base via an adapter. Compared with the prior art, this eliminates the need for the connection between each second connector and the umbrella base, reducing the requirements for assembly precision, reducing the number of assembly steps, and improving assembly efficiency.

[0042] like Figure 3As shown, in one embodiment, the tray 100 includes an upper tray 110 and a lower tray 120 connected axially, and the two are fixedly connected by fasteners such as screws or bolts. The tray 100 has a central hole for a photographic lamp to extend into, and the lower tray 120 is provided with a connecting seat 121 for mounting the photographic lamp. For easy storage, the connecting seat 121 and the lower tray 120 are detachably connected.

[0043] like Figure 5 and Figure 6 As shown, the first connector 310 has a mounting portion 311 that rotatably engages with the base 100, and a fixing portion 312 that is inserted and fixed to the support rod 500. The mounting portion 311 is a sphere, and the fixing portion 312 is a column with an insertion hole. The upper plate 110 and the lower plate 120 are respectively provided with a first mounting cavity and a second mounting cavity. After the upper plate 110 and the lower plate 120 are fixedly connected, the first mounting cavity and the second mounting cavity form a chamber adapted to the mounting portion 311, allowing the first connector 310 to rotate around the center of the sphere. In one embodiment, the base 100 is provided with a circumferentially extending limiting groove 130 corresponding to each first connector 310. The limiting groove 130 is used to limit the movement trajectory of the corresponding first connector 310. The extension direction of each limiting groove 130 is not strictly limited to a radial plane, and the extension lengths of each limiting groove 130 may be the same or different.

[0044] In one embodiment, starting from the adapter 200, the extension length of each limiting groove 130 gradually decreases, that is, the two limiting grooves 130a closest to the adapter 200 have the longest extension length, and the limiting groove 130 farthest from the adapter 200 has the shortest extension length.

[0045] Because the extension length of the limiting groove 130a is relatively long, the first connecting member 310a may experience uneven swinging during unfolding due to friction and other reasons. Blindly performing the unfolding operation may damage the support rod 500 or the reflective cloth 600. In one embodiment, the chuck includes a second reset member 141 that acts on the first connecting member 310a to cause it to swing and unfold, such as... Figure 6 As shown, the disc base 100 is provided with a mounting groove 143 that communicates with the limiting groove 130a. The second reset member 141 is a torsion spring disposed in the mounting groove 143a. The torsion spring has a first working arm 1411 and a second working arm 1412. The first working arm 1411 is located in the mounting groove 143 and abuts against the disc base 100. The second working arm 1412 extends into the limiting groove 130a. When folded, the reflective cloth 600 pulls the first connecting member 310a to swing and compresses and twists the second working arm 1412. When unfolded, the reflective cloth 600 pulls the first connecting member 310a, and at the same time, the second working arm 1412 twists and resets and assists the reflective cloth 600 in driving the first connecting member 310a to swing.

[0046] To prevent the first connector 310a from swinging improperly during folding, the stiffness of the torsion spring can be reduced. Alternatively, in one embodiment, the second action arm 1412 and the first connector 310a are spaced apart in the unfolded state.

[0047] like Figure 2 and Figure 6 As shown, in one embodiment, the adapter 200 has a connecting portion 210 rotatably connected to the base 100, an assembly portion 220 for fixing the second connecting member 320, and a first grip portion 230 extending between two adjacent second connecting members 320. A gap 231 exists between the first grip portion 230 and the assembly portion 220 to facilitate single-handed gripping of the first grip portion 230. The second connecting member 320 protrudes from the assembly portion 220 and the two are integrally formed. The first grip portion 230 is generally a U-shaped plate structure with anti-slip textures on its surface.

[0048] The assembly portion 220 extends circumferentially to connect each of the second connecting members 320. The connecting portion 210 is arranged in the middle of the assembly portion 220 and is relatively recessed circumferentially. Pivot shafts 211 are provided on both sides of the connecting portion 210 in the circumferential direction. The plate base 100 has pivot holes adapted to the pivot shafts 211. For easy assembly, the upper plate 110 and the lower plate 120 are connected to each other to form the pivot holes.

[0049] Furthermore, the base 100 is provided with a second grip 160, which is arranged opposite to the first grip 230. In the figure, the second grip 160 is a roughly U-shaped plate structure and is fixedly connected to the lower plate 120. When unfolding, one hand holds the second grip 160 and the other hand holds the first grip 230.

[0050] like Figure 2 and Figure 4 As shown, the tray 100 has a recessed area 151, and the mounting part 220 is located in the recessed area 151 and flush with the outer peripheral surface of the tray 100. The tray 100 also has another recessed area 152. In the folded state, the mounting part 220 is partially located in the recessed area 152. The adapter 200 rotates approximately 180 degrees from the unfolded state to the folded state. In the figure, the upper plate 110 has a notch that serves as the recessed area 151 and a groove that serves as the recessed area 152.

[0051] To keep the softbox in the unfolded position for normal use, locking member 400 locks adapter 200 in the unfolded position, thereby keeping reflective fabric 600 unfolded. The chuck also includes a release mechanism for unlocking locking member 400.

[0052] like Figure 6As shown, in one embodiment, the locking member 400 has a locking portion 410 and a releasing portion 420 for unlocking the locking member 400, i.e., the locking member 400 also serves as a releasing member. The locking member 400 is radially slidably mounted on the lower plate 120 and has a locked state where the locking portion 410 is engaged with the mounting portion 220, and a unlocked state where the locking portion 410 is disengaged from the mounting portion 220. To facilitate the unlocking operation, the releasing portion 420 is exposed on the outer peripheral surface of the lower plate 120.

[0053] In the diagram, the locking element 400 is roughly L-shaped, the locking part 410 consists of two hooks extending axially, and the release part 420 extends radially with anti-slip texture on its end face. The assembly part 220 is provided with a slot 221 that matches the hooks. In the unfolded state, the release part 420 is located below the first grip part 230. When folded, the release part 420 is pushed to slide radially inward, the hooks disengage from the slot 221, and the reflective cloth 600 and support rod 500 are folded to release stress and drive the adapter 200 to rotate and fold.

[0054] In one embodiment, the chuck further includes a first reset member (not shown) that acts on the locking member 400 to keep it in a locked state. The first reset member, for example a spring, is disposed within the lower plate 120.

[0055] The softbox chuck of this application connects the second connector and the chuck base via an adapter. Compared with the prior art, this eliminates the need for a connection between each second connector and the chuck base, reducing the requirements for assembly precision, decreasing the number of assembly steps, and improving assembly efficiency.

[0056] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0057] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are quite specific and detailed. However, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
