Description

Technical Field

[0001] This utility model belongs to the technical field of photographic auxiliary equipment, and in particular relates to a folding soft light device. Background Technology

[0002] To increase the range of light transmission and enhance the layering of light, softboxes, especially lantern-shaped softboxes, are usually installed in front of photographic lighting equipment. Currently, all lantern-shaped softboxes on the market are non-foldable. When a lantern-shaped softbox needs to be stored, its two ends are relatively parallel, thus supporting multiple support rods to form a relatively three-dimensional structure, which is inconvenient for storage and transportation. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a folding soft light device, wherein the first and second chucks of the chuck can be rotated to overlap, so that at least one end of the soft light device is folded into a flat shape, which is convenient for storage and transportation.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a folding soft light device, including a bracket for mounting a light source, a base disposed opposite to the bracket, and a plurality of support members movably connected between the bracket and the base. The bracket includes a first chuck and a second chuck, which are rotatably connected and can be folded toward the base. Both the first chuck and the second chuck have flared grooves. When the first chuck and the second chuck are rotated and folded, the support members swing along the flared grooves to be housed in the folded annular interior.

[0005] When the diffuser holder of this utility model is folded, multiple support rods are on the same side of the holder, and the support rods of the first and second chucks are vertically opposite each other. The holder is folded into a flat shape, which takes up little storage space and is easy to carry and transport. The flared groove allows the multiple support components of the diffuser to automatically swing to a close-to-each-other state when the holder is folded, making it convenient to use.

[0006] Furthermore, the end of the support member is a ball head, and the first and second chucks are provided with limiting cavities for movably connecting the end of the support member. These limiting cavities are spherical and communicate with the flared groove. The cooperation between the ball head and the spherical cavity makes the rotation of the support rod relative to the limiting cavity more flexible, facilitating the circumferential swing of the support rod within the flared groove.

[0007] Furthermore, the support member includes at least an adapter seat and a rod body, wherein the adapter seat and / or the rod body has a movable cavity. The placement of the movable cavity, assuming that all support members have equal lengths in their unfolded state, solves the problem that the distances between the annular center and both ends of the annular structure and the base are unequal after the first and second chucks are rotated upwards and folded. The movable cavity can be located in the adapter seat, the rod body, or both, allowing for flexible structural design.

[0008] Furthermore, the support member includes an adapter with a ball head and a rod for covering the light-diffusing fabric. The adapter has a hollow interior forming a movable cavity, and the end of the rod is axially movably inserted into the movable cavity of the adapter. The movable cavity, with all rods of equal length, solves the problem that the distances between the annular center and both ends of the annular structure and the base are unequal after the first and second chucks are rotated and folded upwards.

[0009] Furthermore, the rod body includes rod body one and rod body two. Rod body one is connected to the adapter seat, and the end of rod body one connected to rod body two forms the movable cavity. Rod body two is movably inserted into the movable cavity.

[0010] Furthermore, the first chuck and the second chuck are rotatably connected by a shaft located on the bottom surface of the open ends of the first and second chucks. The shaft's location on the bottom surface of the open ends of the first and second chucks facilitates downward folding of the first and second chucks.

[0011] Furthermore, the card holder and the base are concentric and coaxial, with a hanging rod connected to the side of the card holder facing the base, and a hook connected to the side of the base facing the card holder.

[0012] Furthermore, the hanging rod is rotatably connected to the shaft, and a limiting groove is formed at the joint of the first chuck and the second chuck to prevent the hanging rod from shifting. The limiting groove effectively prevents the hanging rod from shifting when the chuck is unfolded and used, ensuring that the hanging rod is in a relatively fixed position, which facilitates the cooperation between the hanging rod and the hook.

[0013] Furthermore, the flaring width of the flaring groove gradually decreases from the opening end of the first chuck. The flaring groove is used to limit the circumferential swing stroke of the support member. The flaring groove is wider near the opening ends of the first and second chucks, and the width of the flaring groove decreases as it moves inward along the circumference. The support member swings more widely near the opening ends of the first and second chucks, allowing it to retract into the annular shape.

[0014] Furthermore, one of the inclined walls of all the flared slots extends radially along the card holder. This ensures that all supports extend radially along the card holder when the diffuser is in the deployed state.

[0015] Furthermore, the flared end sidewall of the flared groove extends obliquely in the circumferential direction. The flared end sidewall, inclined from bottom to top and circumferentially away from the opening end, helps the support to remain in a radially extended state.

[0016] Furthermore, the inner ring of the top surface of the card holder is provided with a receiving groove for a detachable connecting adapter, which is used to connect a light source.

[0017] The beneficial effects of this utility model are: it changes the current situation where the soft light device cannot be folded and stored. When the soft light device holder is folded, multiple support rods are on the same side of the holder, and the support rods of the first and second chucks are vertically opposite each other. The holder is folded into a flat shape, which takes up little storage space and is easy to carry and transport. The flared groove allows the multiple support components of the soft light device to automatically swing to a close-to-each-other state when the holder is folded, making it convenient to use. The unfolding and folding operation of the soft light device is convenient. Attached Figure Description

Detailed Implementation

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention.

[0031] Example 1

[0032] like Figure 1 As shown, a folding diffuser includes a mounting base 1 for a light source, a base 3 opposite to the mounting base 1, multiple support members 2 movably connected between the mounting base 1 and the base 3, and a diffuser cloth (not shown) covering the support members 2. The mounting base 1 and the base 3 are concentrically and coaxially arranged. Applying external force can bring the mounting base 1 and the base 3 closer together, causing the support members 2 to bend and expand the diffuser cloth into a lantern shape, such as... Figure 2 As shown. A hanging rod 18 is connected to the side of the card holder 1 facing the base 3, and a hook 31 is connected to the side of the base 3 facing the card holder 1. When the hanging rod 18 slides into the hook 31, the soft light device can remain in the unfolded and usable state.

[0033] like Figure 3 As shown, the card holder 1 includes a first chuck 11 and a second chuck 12. The first chuck 11 and the second chuck 12 are rotatably connected and can be joined together to form a ring.

[0034] Both the first chuck 11 and the second chuck 12 are provided with flared grooves 13, within which the support member 2 can swing, thereby enabling the soft light device to expand or retract. Specifically, as shown... Figure 4As shown, the flared groove 13 is formed by an inclined wall extending outward from the area where the support member 2 is connected to the card seat 1. Its width gradually increases from the inside to the outside, and it is flared. When the support member 2 swings circumferentially to the point of abutting against the inclined wall of the flared groove 13, it can no longer swing. In other words, the flared groove 13 is used to limit the circumferential swing stroke of the support member 2.

[0035] More specifically, one inclined wall of all the flared slots 13 on the first chuck 11 and the second chuck 12 extends radially along the chuck base 1, so that all the supports 2 extend radially along the chuck base 1 when the light-diffusing device is in the unfolded state. The flared end sidewall 131 of the flared slot 13 extends circumferentially inclined, specifically, as... Figure 6 As shown, the thickness of the flared end sidewall 131 increases gradually from the opening end of the first chuck 11 and the second chuck 12. In other words, the flared end sidewall 131 slopes from bottom to top and circumferentially away from the opening end, which helps the support 2 to remain in a radially extended state.

[0036] like Figure 4 As shown, the first chuck 11 and the second chuck 12 can be rotated and folded towards the base 3. Multiple support members 2 (referring to portions of the support members 2, not the entire support members 2) swing from a radially extended state along the flared groove 13 to a drooping state. That is, the multiple support members 2 on the first chuck 11 droop and approach each other, and the multiple support members 2 on the second chuck 12 droop and approach each other, allowing the support members 2 to be brought closer together. The multiple support members 2 are housed within the folded annular shape; in other words, at least the ends of the multiple support members 2 are housed within the space defined by the folded semi-circular annular shape. This semi-circular annular shape is the semi-circular annular shape formed by the first chuck 11 and the second chuck 12 stacked vertically. Of course, this does not mean that all the support members 2 are inside the folded annular shape, but rather that most of the support members 2, or at least the portion of the support members 2 closest to the base 1, falls into the folded annular shape, or at least falls as close as possible to the folded annular shape.

[0037] by Figure 7 Taking the direction shown as an example, in actual use, the diffuser cloth is located below the card holder 1. The first card 11 and the second card 12 can be rotated and folded downwards. That is, the first card 11 rotates counterclockwise and the second card 12 rotates clockwise until the first card 11 and the second card 12 overlap. The multiple support members 2 swing in the flared groove 13 respectively, so that the support members 2 can be moved downwards and close together, so that the side where the card holder 1 of the diffuser device is located is folded into a flat shape.

[0038] To ensure that the support members 2 can all droop and move closer together, the flared width of the flared groove 13 is different. Specifically, the flared groove 13 near the opening ends of the first chuck 11 and the second chuck 12 is wider, while the width of the flared groove 13 decreases as it moves inward along the circumference. As a result, the support member 2 near the opening ends of the first chuck 11 and the second chuck 12 has a larger swing amplitude, allowing it to retract into the annular shape.

[0039] In this embodiment, the first chuck 11 and the second chuck 12 can be symmetrically arranged, so some reference numerals are not distinguished. Of course, in other embodiments, the first chuck 11 and the second chuck 12 can also be asymmetrically arranged, and there is no specific limitation.

[0040] like Figure 4 , Figure 9 , Figure 10 As shown, the end of the support member 2 is a ball head 21. Both the first chuck 11 and the second chuck 12 are provided with limiting cavities 15 for movably connecting the ball head 21 of the support member 2. These limiting cavities 15 are connected to the flared groove 13 and are spherical. The spherical cavity does not necessarily have to be a complete sphere; it simply means that the limiting cavity 15 has a spherical-like structure. The cooperation between the ball head 21 and the spherical cavity allows the support member 2 to rotate more flexibly relative to the limiting cavity 15, facilitating the swinging of the support member 2 within the flared groove 13.

[0041] The support member 2 includes an adapter 22 with a ball head 21 and a rod 23 for covering the diffuser cloth. The adapter 22 has a hollow interior forming a movable cavity 24. The end of the rod 23 is inserted into the movable cavity 24, and the rod 23 can move axially relative to the movable cavity 24. When the first chuck 11 and the second chuck 12 are flipped and folded downwards, the distance between the middle part of the chuck 1 (more precisely, the annular center of the chuck 1 after folding) and the base 3, and the distance between the two sides of the chuck 1 and the base 3 will be different. When the diffuser device is unfolded, the lengths of all the circumferential support members 2 must be equal. Figure 9 , Figure 10 As shown, the movable cavity 24 solves the above problem. The lengths of each rod 23 are equal. When the first chuck 11 and the second chuck 12 are flipped and folded downwards, the length of the movable cavity 24 can make up for the lengths of the rods 23 on both sides of the chuck seat 1. At this time, the end of the inner rod 23 is located at the bottom of the movable cavity 24, while the end of the outer rod 23 is still some space away from the bottom of the movable cavity 24, thus solving the problem of inconsistent total length between the inner and outer sides.

[0042] In this embodiment, the rod 23 is movably inserted into the movable cavity 24 of the adapter 22. Due to the limitations of the light-diffusing device's mounting base 1 and base 3, the rod 23 will not detach from the adapter 22 as long as the length is designed reasonably. Of course, in other embodiments, an anti-detachment structure can also be provided between the open end of the adapter 22 and the end of the rod 23.

[0043] Of course, the end of the support member 2 does not have to be a ball head structure. It can be an L-shaped bent structure or a T-shaped pivot structure. There are no specific restrictions.

[0044] The limiting cavity 15 forms a notch corresponding to the position of the flared groove 13, and the support member 2 extends from the notch into the flared groove 13.

[0045] like Figure 3 As shown, the first chuck 11 and the second chuck 12 are rotatably connected by a shaft 4. This shaft 4 is located on the bottom surface of the open ends of the first chuck 11 and the second chuck 12, i.e., on the lower side of the chuck base 1 when it is in the unfolded state, and protrudes from the lower surface of the chuck base 1. When the first chuck 11 and the second chuck 12 are unfolded into a ring shape, the end faces of the open ends of the first chuck 11 and the second chuck 12 abut against each other. The symmetrical arrangement of the first chuck 11 and the second chuck 12 facilitates processing and installation.

[0046] The open end of the hanging rod 18 is also rotatably connected to the shaft 4. In order to prevent the hanging rod 18 from shifting at will, the joint of the first chuck 11 and the second chuck 12 forms a limiting groove 19, which wraps around the open end of the hanging rod 18 to prevent it from shifting radially or shaking at will, making the overall structure more stable.

[0047] To facilitate the transfer of light sources, the inner ring 16 of the top surface of the first chuck 11 and the second chuck 12 is provided with a receiving groove 17 for detachably connecting the adapter 5, which is used to connect the light source. A buckle part 171 is provided around the receiving groove 17, and a locking key 51 is provided on the chuck seat 1. By rotating the locking key 51 relative to the chuck seat 1, the adapter 5 can be locked or unlocked.

[0048] For ease of processing and assembly, both the first chuck 11 and the second chuck 12 can be formed by splicing the upper and lower disc bodies, and the aforementioned flared groove 13 is formed by splicing the upper and lower disc bodies.

[0049] When the folding diffuser is in use, the first chuck 11 and the second chuck 12 unfold into a ring shape, with the open ends of the first chuck 11 and the second chuck 12 abutting each other. The hanging rod 18 is firmly restrained and will not shift. The support member 2 is located in the flared groove 13 and extends radially along the card seat 1. Due to the effect of the diffuser cloth, the first chuck 11 and the second chuck 12 remain unfolded upwards. When an external force is applied to bring the card seat 1 and the base 3 closer together, the support member 2 bends and stretches the diffuser cloth to form a lantern shape until the hanging rod 18 and the hook 31 are connected to each other.

[0050] When the diffuser needs to be folded, specifically when the card holder 1 is folded, the hanging rod 18 is disengaged from the hook 31. Under the automatic reset force of the support 2, the diffuser retracts, and the first chuck 11 and the second chuck 12 rotate and fold towards the base 3. The support 2 swings down in the flared groove 13, so that multiple support 2 move closer to the base 3 and retract. The support of the first chuck 11 and the support of the second chuck 12 are vertically opposite each other (this refers to the diffuser being placed horizontally). Finally, the side of the diffuser where the card holder 1 is located is folded into a flat shape. Since the outer diameter of the base 3 is smaller than the outer diameter of the card holder 1, the overall volume is small after folding, making it easy to store.

[0051] Example 2

[0052] like Figure 11 As shown, in this embodiment, the rod 23 includes a first rod 231 and a second rod 232. The upper end of the first rod 231 is connected to the adapter 22. At this time, the adapter 22 may not have a movable cavity 24. The upper end of the first rod 231 and the adapter 22 can be fixedly connected. The lower end of the first rod 231 is provided with a movable cavity 24. The upper end of the second rod 232 is movably inserted into the movable cavity 24.

[0053] Thus, when the top of the second rod 232 abuts against the end of the movable cavity 24, the lengths of the support members 2 are equal. When the first chuck 11 and the second chuck 12 are flipped and folded upwards, the second rod 232 can move within the movable cavity 24. The length of the movable cavity 24 can compensate for the length of the middle part of the rod 23 in the chuck seat 1, thus solving the problem of inconsistent total lengths on the inner and outer sides.

[0054] Of course, the movable cavity 24 can also be set at the upper end of the rod 232.

[0055] The other structures are the same as in Embodiment 1, and will not be described again.

[0056] Example 3

[0057] In this embodiment, the number of movable cavities 24 can be two, that is, not only are movable cavities provided on the adapter 22, but also between rod body one 231 and rod body two 232. In other words, it is a combination of the structure of embodiment one and the structure of rod body 23 in embodiment two.

[0058] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
