DETAILED DESCRIPTION

[0029] The typical embodiments embodying the features and advantages of the present application will be described in detail in the following description. It should be understood that the present application can be varied in a wide range of embodiments, none of which depart from the scope of the present application, and that the description and drawings are to be considered as illustrative only, and not restrictive in nature.

[0030] In the description of the present application, it should be understood that in the embodiments shown in the drawings, the indications of direction or positional relationship (such as up, down, left, right, front and back, etc.) are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation. When these elements are in the position shown in the drawings, these descriptions are appropriate. If the position of these elements changes, the indications of direction also change accordingly.

[0031] In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implying the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0032] Please refer to Figures 1 to 9 The embodiment of the present application provides a lamp soft box 100, which comprises a telescopic support frame 20, an elastic bone strip 10 and a soft cloth (not shown in the figure).

[0033] The two ends of the telescopic support frame 20 can be close to each other or away from each other, so that the length of the telescopic support frame 20 changes. The plurality of elastic ribs 10 are arranged around the telescopic support frame 20. The soft light cloth is tightly attached to the outside or inside of the elastic rib 10 and is shaped by the support of the elastic rib 10. After the soft light cloth is shaped by support, light can be emitted through the soft light cloth. The soft light cloth can perform soft light processing on the passing light, avoid the light being too dazzling, and ensure that the light is uniformly distributed, thereby effectively improving the light effect in photography and videography.

[0034] The elastic rib 10 extends along the axis direction of the telescopic support frame 20, and the two ends of each elastic rib 10 are fixed with the two ends of the telescopic support frame 20. When the two ends of the telescopic support frame 20 are close to each other to shorten the overall length, the elastic rib 10 elastically bends to expand the lantern soft light box 100. When the two ends of the telescopic support frame 20 are away from each other to lengthen the overall length, the lantern soft light box 100 is in a storage state. The lantern soft light box 100 in the storage state is in a cylindrical shape, and the diameter is comparable to the diameter of the first and second chucks, greatly saving the storage space.

[0035] Please refer to Figure 4 and Figure 5 In some embodiments, the telescopic support frame 20 includes a first sliding frame 21 and a second sliding frame 22.

[0036] The first sliding frame 21 and the second sliding frame 22 are slidingly connected, so that the first sliding frame 21 and the second sliding frame 22 can be close to or away from each other, and then the two ends of the telescopic support frame 20 are close to or away from each other to change the overall length of the telescopic support frame 20, so that the elastic rib 10 on the telescopic support frame 20 can be expanded.

[0037] Please refer to Figures 4 to 6 In some embodiments, the first sliding frame 21 includes a first chuck 211, a first support disc 212, and two or more first support rods 213. The first support rod 213 is arranged between the first chuck 211 and the first support disc 212, and the two ends of the first support rod 213 are fixed with the first chuck 211 and the first support disc 212, respectively.

[0038] The second sliding frame 22 includes a second chuck 221, a second support disc 222, and two or more second support rods 223. The second support rod 223 is arranged between the second chuck 221 and the second support disc 222, and the two ends of the second support rod 223 are fixed with the second chuck 221 and the second support disc 222, respectively.

[0039] The first support disc 212 is located between the second chuck 221 and the second support disc 222, and is slidably connected to the outer side of the second support rod 223, with the sliding direction of the first support disc 212 being consistent with the extending direction of the second support rod 223. The second support disc 222 is located between the first chuck 211 and the first support disc 212, and is slidably connected to the outer side of the first support rod 213, with the sliding direction of the second support disc 222 being consistent with the extending direction of the first support rod 213. The two ends of the elastic bone strip 10 are respectively connected to the first chuck 211 and the second chuck 221 on the telescopic support frame 20.

[0040] When the first support disc 212 slides relative to the second support rod 223, and the second support disc 222 slides relative to the first support rod 213, the first chuck 211 and the second chuck 221 at the two ends of the telescopic support frame 20 move away from or close to each other, so as to change the length of the telescopic support frame 20, and further enable the elastic bone strip 10 on the first support disc 212 and the second support disc 222 to bend or stretch.

[0041] Through the connection mode of the first sliding frame 21 and the second sliding frame 22, not only the length adjustment of the telescopic support frame 20 can be realized, but also the structural strength of the telescopic support frame 20 can be ensured by the two or more first support rods 213 and the two second support rods 223, so that the telescopic support frame 20 can bear a larger load. Especially when the lantern soft light box 100 needs to bear a larger size and weight, it can provide reliable support to effectively avoid deformation, tilting or damage of the support frame due to gravity or external force, thereby greatly improving the stability and durability of the entire lantern soft light box 100.

[0042] Please refer to Figure 6 In some embodiments, the first support disc 212 is provided with a first through hole 2122 corresponding to the second support rod 223. The second support rod 223 is arranged in the first through hole 2122, so that the first support disc 212 can slide along the axis of the second support rod 223. The second support disc 222 is provided with a second through hole 2222 corresponding to the first support rod 213, and the first support rod 213 is arranged in the second through hole 2222, so that the second support disc 222 can slide along the axis of the first support rod 213.

[0043] Specifically, the first support disc 212 is provided with a first through hole 2122 to allow the second support rod 223 to pass through, so that the first support disc 212 can slide along the second support rod 223, and the second support disc 222 is provided with a second through hole 2222 to allow the first support rod 213 to pass through, so that the second support disc 222 can slide with the first support rod 213, to realize the sliding connection between the first sliding frame 21 and the second sliding frame 22. It can make the first sliding frame 21 and the second sliding frame 22 more stable when they slide relative to each other, so that the length adjustment of the telescopic support frame 20 is stable and reliable.

[0044] Of course, in other embodiments, the first support disc 212 and the second support rod 223, and the second support disc 222 and the first support rod 213 can also realize sliding connection in the way of external sliding block and sliding rail. As long as it can meet the relative sliding between the first sliding frame 21 and the second sliding frame 22, and does not interfere with each other.

[0045] Please refer to Figure 6 In some embodiments, the side of the first support disc 212 facing the first chuck 211 is also provided with a first fixing position 2121. The first fixing position 2121 is arranged one by one with the first support rod 213, so that the end of the first support rod 213 can be fixed with the first fixing position 2121 of the first support disc 212, to realize the fixed connection of the first sliding frame 21. And supported by the elastic bone strip; after the soft light cloth support is formed, the light of the photography and videography lamp can be emitted through the soft light cloth.

[0046] Correspondingly, the side of the second support disc 222 facing the second chuck 221 is provided with a second fixing position 2221. The second fixing position 2221 is arranged one by one with the second support rod 223, so that the end of the second support rod 223 can be fixed with the second support disc 222, to realize the fixed connection of the second sliding frame 22.

[0047] Please refer to Figures 4 to 6 In some embodiments, a plurality of first support rods 213 and a plurality of second support rods 223 are alternately arranged around the circumferential side of the first support disc 212 or the second support disc 222.

[0048] Specifically, the first support disc 212 is of annular structure, and the first fixing positions 2121 and the first through holes 2122 in the circumferential direction of the first support disc 212 are alternately arranged, so that the first support rods 213 and the second support rods 223 are alternately arranged in the circumferential direction of the first support disc 212. Correspondingly, the second support disc 222 is also of annular structure, and the second fixing positions 2221 and the second through holes 2222 in the circumferential direction of the second support disc 222 are also alternately arranged, so that the second support rods 223 and the first support rods 213 are also alternately arranged in the circumferential direction of the second support disc 222.

[0049] The first support rods 213 and the second support rods 223 are alternately arranged along the circumferential direction of the first support disc 212 or the second support disc 222, achieving uniform distribution of all the support rods on the telescopic support frame 20. Since the support rods are arranged in an alternating manner, each support rod can share the corresponding load, thereby avoiding the problem of structural deviation caused by uneven load distribution due to the concentrated arrangement of the support rods. Especially when the flexible rib 10 of the lantern soft light box 100 is bent, the alternately arranged support rods can more effectively disperse the stress, ensuring the stability of the telescopic support frame 20 when it is expanded.

[0050] Please refer to Figures 4 to 6 In some embodiments, the number of first support rods 213 and second support rods 223 is greater than or equal to three.

[0051] In some embodiments, the number of first support rods 213 and second support rods 223 is greater than or equal to three.

[0052] Of course, in other embodiments, the number of first support rods 213 and second support rods 223 can be two. Moreover, the number of first support rods 213 and second support rods 223 can be set to the same number, or the number of first support rods 213 and second support rods 223 can be set to different numbers according to the different stress on both ends of the lantern soft light box 100.

[0053] Please refer to Figure 5 and Figure 7 In some embodiments, the length of the first support rod 213 is the same as the length of the second support rod 223. The length of the first support rod 213 plus the length of the second support rod 223 is equal to the length of the flexible rib 10.

[0054] Specifically, the length of the first support rod 213 and the length of the second support rod 223 are the same, which can make the telescopic support frame 20 compress the distance between the first chuck 211 and the second chuck 221 to the length of the first support rod 213 or the second support rod 223 when the first sliding frame 21 and the second sliding frame 22 are relatively close, that is, the shortest length of the telescopic support frame 20 is approximately the same as the length of the first support rod 213 or the second support rod 223. Thus, the overall structure of the telescopic support frame 20 is more compact.

[0055] And the total length of the first support rod 213 and the second support rod 223 is equal to the length of the elastic bone strip 10, so that when the first sliding frame 21 and the second sliding frame 22 are away from each other, the elastic bone strip 10 can completely recover from the curved state to the straight linear state, so that the lantern soft light box 100 can be kept in the cylindrical state.

[0056] Please refer to Figure 8 and Figure 9 In some embodiments, the telescopic support frame 20 further comprises a locking assembly 23. The locking assembly 23 is arranged between the first support disc 212 and the second chuck 221. When the first support disc 212 slides along the second support rod 223 and abuts against the second chuck 221, the locking assembly 23 can fix the first support disc 212 and the second chuck 221 to lock the first sliding frame 21 and the second sliding frame 22.

[0057] Wherein, when the first support disc 212 slides along the second support rod 223, until the first support disc 212 abuts against the end face of the second chuck 221, the locking assembly 23 can fix the positions of the first support disc 212 and the second chuck 221 to ensure that the relative positions between the first sliding frame 21 and the second sliding frame 22 do not change.

[0058] It is conceivable that the locking assembly 23 can be a latch, a knob, a buckle or the like structure, which can effectively fix the length of the telescopic support frame 20 to prevent the telescopic support frame 20 from loosening during use, and ensure the stability of the lantern soft light box 100 in use.

[0059] Please refer to Figure 8 and Figure 9 In some embodiments, the locking assembly 23 comprises a fixing rod 231 arranged on the first support disc 212, a fixing groove 232 arranged on the second chuck 221, and a latch 233 inserted into the fixing groove 232. The latch 233 can be inserted into the fixing groove 232 to block the fixing rod 231 in the fixing groove 232 to fix the first support disc 212 and the second chuck 221.

[0060] Specifically, the fixing rod 231 is arranged at the middle position of the annular first support disc 212. The annular second chuck 221 is provided with a cross rod, and the fixing groove 232 is arranged on the side of the cross rod facing the fixing rod 231 to accommodate the fixing rod 231. The sidewall of the fixing groove 232 of the cross rod is provided with a insertion hole 234 for inserting the latch 233.

[0061] When the first support disc 212 slides along the second support rod 223 and abuts against the second chuck 221, the fixing rod 231 will enter the fixing slot 232. At this time, the latch 233 is inserted into the insertion hole 234 on the side of the fixing slot 232, so that the fixing rod 231 can no longer be separated from the fixing slot 232, ensuring that the first support disc 212 and the second chuck 221 remain stationary in relative position, thereby locking the first sliding frame 21 and the second sliding frame 22 together, and keeping the softbox 100 in the open state.

[0062] Through the cooperation of the fixing rod 231, the fixing slot 232 and the latch 233, the locking assembly 23 can simply and firmly lock the position of the telescopic support frame 20, and the locking and unlocking are very simple, and can withstand a large external force without loosening or unlocking phenomenon. The whole operation does not require complex tools or avoids the use of other complex mechanisms, making the structure design more simple and practical,

[0063] Please refer to Figure 6 In some embodiments, the softbox 100 further comprises a plurality of connecting pieces. The connecting pieces are rotatably connected to the outer circumferential side of the first chuck 211 and the second chuck 221. The two ends of the elastic rib 10 are respectively detachably connected to the connecting pieces on the first chuck 211 and the second chuck 221.

[0064] The connecting pieces include a plurality of first connecting pieces 2113 and a plurality of second connecting pieces 2213. The first connecting pieces 2113 and the second connecting pieces 2213 are the same structure. The first connecting pieces 2113 are arranged on the first chuck 211, and the second connecting pieces 2213 are arranged on the second chuck 221. The free end of each first connecting piece 2113 and second connecting piece 2213 is provided with a connecting hole on the end face, which is used for butt joint with the end of the elastic rib 10.

[0065] Specifically, as Figure 6 shown, the first chuck 211 includes a first disc body 2111 and a first top cover 2112. The circumferential direction of the first disc body 2111 is provided with a plurality of mutually spaced protruding blocks, and the protruding blocks are provided with rotating grooves. The first connecting pieces 2113 are arranged between adjacent protruding blocks. The first connecting pieces 2113 are provided with rotating rods, and the two ends of the rotating rods are accommodated in the rotating grooves of the protruding blocks. The first top cover 2112 is fixed and pressed onto the first disc body 2111 by screws, so as to fix one end of the first connecting piece 2113 on the first chuck 211, and enable the first connecting piece 2113 to rotate relative to the first disc body 2111.

[0066] Correspondingly, the second chuck 221 has substantially the same structure as the first chuck 211. The second chuck 221 also includes a second disc body 2211 and a second top cover 2212, a plurality of second connecting members 2213 are arranged around the second disc body 2211, and the second top cover 2212 is press-fitted on the second disc body 2211 to realize the rotation connection of the second connecting members 2213 with the second chuck 221.

[0067] When the elastic bone strip 10 is bent under force, the connecting members can rotate relative to the first chuck 211 and the second chuck 221, so that the angle of the connecting members adapts to the curvature of the elastic bone strip 10, to prevent the elastic bone strip 10 from breaking.

[0068] Please refer to Figure 6 In some embodiments, the first chuck 211 is provided with a clamping ring 2114 on the end face away from the first support disc 212, and the clamping ring 2114 is used to connect with an external photographic camera lamp.

[0069] Specifically, the first chuck 211 is provided with a clamping ring 2114, which can adapt to photographic camera lamps of different specifications to provide a stable connection interface and prevent the lamp from moving or loosening during use. By connecting the photographic camera lamp through the clamping ring 2114, the user can quickly complete the installation of the lamp, without the need for complex tools or operations, thereby improving work efficiency, and the device is particularly suitable for use in photographic studios or on-site shooting.

[0070] Please refer to Figure 6 In some embodiments, the first chuck 211 and the second support disc 222 are provided with opposite light inlet openings 2115, and the light inlet openings 2115 are used for the light emitted by the photographic camera lamp or the lamp tube thereof to enter.

[0071] The first chuck 211 and the second support disc 222 are provided with opposite light inlet openings 2115, which can be used for the light to directly enter, or the lamp tube of the photographic camera lamp to be inserted into the inside of the telescopic support frame 20, so that the light is uniformly scattered by the soft light cloth of the lampshade soft light box 100.

[0072] In summary, the embodiment provides a telescopic support frame 20 and a lantern soft light box 100.
