Description

Technical Field

[0001] The utility model belongs to the technical field of photography auxiliary equipment, in particular to an elastic supporting structure for a soft box chuck and a soft box chuck mechanism. Background Art

[0002] In the existing soft box chuck mechanism, the user needs to manually move the support rod to an extended or retracted state to open or fold the soft light cloth. In this process, since some support rods are retracted to a large extent, the user needs to spend more effort to unfold and reset them.

[0003] Chinese patent CN221225281U discloses "An installation ring mechanism for a photographic light reflector device", which installs a retracting button in the adjustment component. By pressing the retracting button, the clamping springs and the rod sleeve clamping parts on both sides are pressed, and the rod sleeve clamping parts rotate downward with the rotating shafts on both sides as the central axis. Under the tension of the reflective cloth support rod, the movable rod sleeve will rebound to the retracted state to achieve the storage of the soft box. However, when the soft box is opened, the user needs to manually lift the movable rod sleeves one by one and press them with the rod sleeve clamping parts to achieve the unfolded state of the soft box, which is more laborious to use. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the utility model provides an elastic support structure for a softbox chuck and a softbox chuck mechanism, which realizes automatic resetting of the support rod after being folded, and quickly unfolds the support rod without the need for the user to manually bend the support rod back to its original position, thereby saving effort and being easy to use.

[0005] The technical solution adopted by the utility model to solve its technical problems is: an elastic support structure for a soft box chuck, the soft box chuck is movably connected with a support rod, the elastic support structure at least includes an elastic reset member, the elastic reset member has a fixed end, a first elastic action end, and a second elastic action end that can be abutted against the support rod; the support rod can be moved to an expanded state or a retracted state relative to the soft box chuck, and the second elastic action end is used to press the support rod toward the expanded state.

[0006] The utility model uses an elastic support structure to press the support rod toward the expanded state, which is convenient for rapid expansion of the support rod and does not require the user to manually bend the support rod back to its original position, thus saving effort and being easy to use; at the same time, it plays a stable fixing role on the support rod, ensuring that the support rod is in a stable expanded state.

[0007] Furthermore, the elastic support structure also includes a mounting seat, which has a fixing column that can be connected to the fixed end, an abutting side wall that can abut against the first elastic action end, and a limiting groove for the first elastic action end to extend into. The setting of the mounting seat facilitates the stable installation of the elastic reset member and prevents the elastic reset member from shifting.

[0008] Furthermore, the softbox chuck is formed with an expansion cavity, at least a portion of which is sunken to form a mounting groove, and a portion of the mounting seat is clamped in the mounting groove. The mounting groove provides an installation space for the mounting seat to prevent the mounting seat from shifting during the folding or unfolding of the softbox, and the mounting groove has a simple structure and is easy to process.

[0009] Furthermore, a positioning and mounting structure is formed between the wall surface of the expansion cavity and the abutting side wall and the mounting seat, so as to fix the mounting seat and prevent the mounting seat from moving in the mounting groove or detaching from the mounting groove to cause the parts to be lost.

[0010] Furthermore, the positioning and mounting structure includes a convex rib located on the wall surface where the expansion cavity abuts against the abutting side wall, and a groove body located on the outer surface of the abutting side wall of the mounting seat. When the mounting seat and the soft box chuck are assembled, the groove body is sleeved on the outer side of the convex rib. The positioning and mounting structure is simple to set up, and there is no need to change the original soft box structure. It only needs to add convex ribs inside the original soft box, which simplifies the processing steps and reduces the processing difficulty.

[0011] Furthermore, the cross section of the mounting seat is U-shaped, and includes a top wall and a bottom wall located on the upper and lower sides of the abutting side wall. The U-shaped structure of the mounting seat reserves space for the folding of the support rod, which does not affect the normal use of the support rod; the top wall and the bottom wall of the mounting seat can abut against the soft box chuck, and the overall assembly structure is stable. The abutting side wall of the mounting seat facilitates the setting of the positioning installation structure, and also makes the overall structure of the mounting seat more stable.

[0012] Furthermore, the elastic reset member has two fixed ends and two first elastic action ends, the two second elastic action ends are connected as one body, and the mounting seat has two fixed columns and two limiting grooves, which are respectively located on the top wall and the bottom wall. The structural setting of the elastic reset member increases its contact area with the support rod, ensuring a stable pressure on the support rod. The fixed column and the limiting groove are used in conjunction with the elastic reset member to fix the position of the elastic reset member from the upper and lower ends, thereby playing a better fixing role and preventing the elastic reset member from moving during the extrusion or expansion process, thereby affecting the pressure on the support rod toward the expanded state; at the same time, it can also avoid the loss of the elastic reset member.

[0013] Furthermore, the elastic reset element is a torsion spring, which is easy to obtain and has low processing cost.

[0014] Furthermore, a soft box chuck mechanism includes an annular soft box chuck, a plurality of support rods movably connected to the soft box chuck, and the above-mentioned elastic support structure.

[0015] Furthermore, at least one through groove is provided on the lower surface of the soft box chuck, and the support rod includes a first support rod and a second support rod, the first support rod is movably connected to the through groove, and the second support rod arranged near the first support rod is provided with an elastic support structure. Since the second support rod arranged near the first support rod has the largest swing amplitude when folded or unfolded compared with other second support rods, the user needs to fold or unfold it manually, which is relatively laborious, so an elastic support structure is provided at the second support rod arranged near the first support rod to ensure that the second support rod here is smoothly unfolded, so that the user can save time and effort when unfolding the soft box.

[0016] The beneficial effects of the utility model are: 1) The support rod is pressed toward the unfolded state by the elastic support structure, which facilitates the rapid unfolding of the support rod. The user does not need to manually bend the support rod back to its original position, which saves effort and is easy to use; 2) After the two second elastic action ends are connected as one, the overall columnar structure is used to resist the support rod, and the support rod will not separate from the second elastic action end, thereby exerting a stable pressing effect and fixing effect on the support rod. 3) The positioning and installation structure is simple to set up, and there is no need to change the original soft box structure. It only needs to add ribs inside the original soft box to fix the mounting seat, which can avoid the loss of parts, simplify the processing steps, and reduce the processing difficulty. 4) The overall structure of the elastic support structure is simple and easy to process.

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the solution of the utility model, the following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0027] like Figure 1-Figure 8 As shown, an elastic support structure for a soft box chuck, the soft box chuck 1 is movably connected to a support rod 2, and the support rod 2 can swing circumferentially along the soft box chuck 1; the elastic support structure at least includes an elastic reset member 3, the elastic reset member 3 has a fixed end 31, a first elastic action end 32 and a second elastic action end 33, wherein the second elastic action end 33 is against the support rod 2.

[0028] Specifically, the support rod 2 can move relative to the soft box chuck 1 to an extended state or a retracted state. Figure 1-Figure 3 As shown, the support rod 2 extends radially along the soft box chuck 1 and is located close to the same plane as the soft box chuck 1. The second elastic action end 33 abuts against the support rod 2 to press the support rod 2 toward the expanded state, ensuring that the support rod 2 is in a stable expanded state, thereby fully expanding the soft box. In the folded state, as shown in FIG. Figure 3 Taking the direction shown as an example, the support rod 2 is retracted to the left, and the second elastic action end 33 is squeezed to move closer to the first elastic action end 32 to achieve folding of the soft box; when the support rod 2 is unfolded again, the elastic reset member 3 restores its deformation, pushing the second elastic action end 33 away from the first elastic action end 32, and then pressing the support rod 2 in the direction of the unfolded state, which facilitates the rapid unfolding of the support rod 2 and does not require the user to manually bend the support rod 2 back to its original position, saving effort and being easy to use.

[0029] like Figure 3 As shown, the elastic reset member 3 has two fixed ends 31, two first elastic action ends 32 and two second elastic action ends 33. The two fixed ends 31, the two first elastic action ends 32 and the two second elastic action ends 33 are all arranged opposite to each other up and down, and the ends of the two second elastic action ends 33 are bent and connected together, so that the elastic reset member 3 forms a whole. Of course, the ends of the two first elastic action ends 32 can also be connected together to ensure that when the support rod 2 is unfolded, the two first elastic action ends 32 and the two second elastic action ends 33 can simultaneously exert force to push the support rod 2 to unfold; and after the two second elastic action ends 33 are connected as one, the overall columnar structure is against the support rod 2, increasing the contact area between the support rod 2 and the support rod 2, and the support rod 2 will not be separated from the second elastic action ends 33, thereby playing a stable pressing and fixing effect on the support rod 2. Compared with a single elastic action end, only the end portion is against the support rod 2, and the contact surface is only point contact. The pushing force on the support rod 2 is small, which is not enough to push the support rod 2 to the expanded state. Moreover, the support rod 2 is a cylinder with a smooth surface. The end portion of the single elastic action end is easy to slide relative to the support rod 2, affecting the expansion of the support rod 2.

[0030] In this embodiment, the elastic return member 3 is a torsion spring. Of course, in other embodiments, the elastic return member 3 can be made of other elastic materials, which is not specifically limited.

[0031] like Figure 6-Figure 8 As shown, the elastic support structure also includes a mounting seat 4, which is used for the stable installation of the elastic reset member 3 to prevent the elastic reset member 3 from shifting. The mounting seat 4 includes an abutting side wall 42, a top wall 44 and a bottom wall 45 located on the upper and lower sides of the abutting side wall 42, and a fixing column 41 and a limiting groove 43 located on the top wall 44 and the bottom wall 45. In this embodiment, the overall cross-section of the mounting seat 4 is U-shaped, which reserves space for the folding of the support rod 2 without affecting the normal use of the support rod 2. The top wall 44 and the bottom wall 45 of the mounting seat 4 can abut against the soft box chuck 1, and the overall assembly structure is stable. The abutting side wall 42 of the mounting seat 4 facilitates the setting of the positioning installation structure, and also makes the overall structure of the mounting seat 4 more stable.

[0032] Furthermore, the fixed column 41 is connected to the fixed end 31 and is adapted in size to the hollow portion of the fixed end 31. The fixed end 31 is sleeved on the outer periphery of the fixed column 41 to fix the position of the elastic reset member 3 to prevent the position of the elastic reset member 3 from moving and affecting the pressing effect on the support rod 2; the limiting groove 43 allows at least part of the first elastic action end 32 to extend into to limit the position of the first elastic action end 32.

[0033] In this embodiment, there are two fixing columns 41 and two limiting grooves 43, which are used in conjunction with the elastic reset member 3. Figure 7Taking the direction shown as an example, the fixing column 41 and the limiting groove 43 fix the position of the elastic return member 3 from the upper and lower ends, which plays a better fixing role and prevents the elastic return member 3 from moving during the extrusion or expansion process, thereby affecting the pressure on the support rod 2 toward the expanded state; at the same time, it can also avoid the loss of the elastic return member 3.

[0034] like Figure 3-Figure 5 As shown, the softbox chuck 1 is formed with an expansion cavity 11 for accommodating the support rod 2 in the folded state, reducing the space occupied by the support rod 2 and facilitating storage. At least a portion of the expansion cavity 11 is recessed downward to form a mounting groove 12, and a portion of the mounting seat 4 is clamped in the mounting groove 12, providing an installation space for the mounting seat 4 and preventing the mounting seat 4 from shifting during the folding or unfolding of the softbox.

[0035] Furthermore, a positioning and mounting structure is formed between the wall surface of the expansion cavity 11 and the abutting side wall 42 and the mounting seat 4. Specifically, Figure 3 , Figure 8 As shown, the positioning and mounting structure includes a convex rib 51 located on the wall surface where the expansion cavity 11 abuts against the side wall 42, and a groove body 52 located on the outer surface of the mounting seat 4 abutting against the side wall 42. When the mounting seat 4 is assembled with the soft box chuck 1, the groove body 52 only needs to be sleeved on the outer side of the convex rib 51 to fix the mounting seat 4, thereby preventing the mounting seat 4 from moving in the mounting groove 12 or the mounting seat 4 from being separated from the mounting groove 12, resulting in the loss of parts.

[0036] The positioning and installation structure in this embodiment is simple to set up, and there is no need to change the original soft box structure. It only needs to add convex ribs 51 inside the original soft box, which simplifies the processing steps and reduces the processing difficulty.

[0037] like Figure 1 , Figure 2 As shown, a soft box chuck mechanism includes an annular soft box chuck 1, a plurality of support rods 2 movably connected to the soft box chuck 1, and an elastic support structure, which is the same as the above structure and will not be described in detail.

[0038] At least one through groove 13 is provided on the lower surface of the soft box chuck 1, and the support rod 2 includes a first support rod 21 and a second support rod 22, wherein the first support rod 21 is movably connected to the through groove 13. Since the second support rod 22 arranged near the first support rod 21 has the largest swing amplitude when folded or unfolded compared with other second support rods 22, the user needs to fold or unfold it manually, which is more laborious. Therefore, an elastic support structure is provided at the second support rod 22 arranged near the first support rod 21 to ensure that the second support rod 22 here is smoothly unfolded, so that the user can save time and effort when unfolding the soft box.

[0039] Specifically, in the unfolded state, the first support rod 21 and the second support rod 22 extend radially along the soft box chuck 1 and are close to a position in the same plane as the soft box chuck 1. The elastic reset member 3 abuts against the second support rod 22 arranged close to the first support rod 21 to fix the position of the second support rod 22, thereby ensuring that the support rod 2 stably holds the soft box open; in the folded state, the first support rod 21 approaches the lower surface of the soft box chuck 1, thereby moving into the through groove 13 and fitting the lower surface of the soft box chuck 1, and the second support rod 22 swings circumferentially along the soft box chuck 1, and the elastic reset member 3 is squeezed, and finally the soft box is tied together with a strap to achieve folding of the soft box; when the support rod 2 is unfolded again, the elastic reset member 3 restores its deformation and pushes the second support rod 22 arranged close to the first support rod 21 to automatically unfold, thereby making it easier for the user to unfold the soft box.

[0040] The above specific implementation modes are used to explain the present invention rather than to limit the present invention.
