The relative position of the light-blocking plate and the mounting base is fixed, meaning the vertical distance between their centers is fixed. Chinese patent CN219320629U discloses a "radome," in which a reflector is connected to a base via a support, and the relative position of the reflector and the base is fixed. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the present invention provides an adjustable reflective device, which is connected to different groups of transition points through a light blocking member, thereby changing the light refraction path to adapt to different shooting scenes.

[0004] The technical solution adopted by the utility model to solve its technical problems is: an adjustable reflective device, including a reflector and a light blocking member, the reflector having a mounting hole for connecting a light source, the light blocking member being arranged in a space enclosed by the reflector and corresponding to the mounting hole, the reflective surface of the reflector being provided with at least two groups of transition points radially spaced apart, the light blocking member being detachably connected to the transition points through a connecting member, and the light blocking member selectively connecting different groups of transition points to change the vertical distance between the light blocking member and the mounting hole.

[0020] In order to enable those skilled in the art to better understand the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0021] like Figure 1-Figure 3 As shown, an adjustable reflective device includes a reflector 1 and a light-blocking member 2. The reflector 1 has a mounting hole 11 for connecting to a light source. The light-blocking member 2 is disposed within the space enclosed by the reflector 1 and corresponds to the mounting hole 11. The reflector 1 has a light-shielding surface on its outer side and a reflective surface 12 on its inner side. At least two groups of transition points 3 are radially spaced apart on the reflective surface 12. The light-blocking member 2 is detachably connected to the transition points 3 via a connector 4. When the light-blocking member 2 is selectively connected to different groups of transition points 3, in other words, when the light-blocking member 2 is selectively connected to different radially positioned groups of connection points 3, the vertical distance between the light-blocking member 2 and the mounting hole 11 changes, thereby changing the vertical distance between the light-blocking member 2 and the light source on the mounting hole 11. Consequently, the refraction path of light through the light-blocking member 2 and the reflective surface 12 changes.

[0022] The reflector 1 here is not limited to an umbrella-shaped softbox, and the corresponding arrangement of the light blocking member 2 and the mounting hole 11 is not limited to the light blocking member 2 and the mounting hole 11 being completely opposite each other. In this embodiment, the reflector 1 is formed by splicing a plurality of reflective sheets 13 into an umbrella shape, the center of which is provided with a mounting hole 11, and the light blocking member 2 is concentrically and coaxially arranged with the mounting hole 11. The transition point 3 is located at the joint of adjacent reflective sheets 13, which not only does not affect the reflective effect of the reflective sheets 13, but also facilitates processing. In order to facilitate processing and assembly, the transition point 3 is an adapter ring formed by bending a flexible material, and the opening of the adapter ring is sewn between adjacent reflective sheets 13. It should be noted that Figure 1 The reflector 1 in the shown state forms a projection on one side of the plane where its opening is located. The radial direction of the projection is defined as the radial direction of the reflector 1, and the side close to the mounting hole 11 is the radial inner side.

[0023] One group of transition points includes two or more transition points 3 spaced apart along the circumference of the reflector 1, and two or more groups of transition points spaced apart along the radial direction of the reflector 1. In this embodiment, one group of transition points includes four transition points 3 located in the same radial direction of the reflector 1 and spaced apart evenly along the circumference, and the number of groups of transition points 3 is three. In other words, Figure 1 In the plane projection of the state shown, the circle formed by connecting the four transfer points 3 in the same group is concentric with the mounting hole 11. The circumferential connecting lines of the three groups of transfer points 3 are three concentric circles radiating from the inside to the outside.

[0024] In this embodiment, the light blocking member 2 includes a protruding body 21 that arches from the side where the mounting hole 11 is located toward the inside of the reflector 1, and an edge 22 located at the outer periphery of the protruding body 21. Figure 5 Taking the direction shown as an example, the protruding body 21 arches from the left to the right, and the edge 22 extends in a plane. The edge 22 is evenly spaced around the edge 22 with perforations 221. The number of perforations 221 is the same as the number of each set of transfer points 3. The connecting member 4 is an elastic cord, one end of which is connected to the perforation 221 and the other end is detachably connected to the transfer point 3. Figure 4 As shown, in this embodiment, the elastic cord is passed through the through-hole 221 and then folded in half. One end of the elastic cord is hung in the through-hole 221, and the other end is fixedly connected to the existing hook 41. The hook 41 is detachably connected to the transfer point 3. The elastic cord used for the connector 4 ensures that when the same connector 4 connects the light blocking member 2 to different groups of transfer points 3, the light blocking member 2 can be kept in a taut state, ensuring that the light blocking member 2 is aligned with the mounting hole 11.

[0025] like Figure 5 As shown, when the light blocking member 2 is assembled and connected to a group of transfer points 3 on the inner side near the mounting hole 11 through the connecting member 4, the vertical distance between the light blocking member 2 and the center of the mounting hole 11 is small, the light source is irradiated on the light blocking member 2, and the light is reflected by the light blocking member 2 to the reflective surface 12. The light refracted by the reflective surface 12 (the part shown by the dotted line) is closer to the middle of the reflector 1.

[0026] like Figure 6 As shown, when the light blocking member 2 is assembled and connected to a group of adapter points 3 farther from the mounting hole 11 via the connector 4, the vertical distance between the light blocking member 2 and the center of the mounting hole 11 increases. When the light source shines on the light blocking member 2, the light is reflected by the light blocking member 2 to the reflective surface 12. The light refracted by the reflective surface 12 (the portion shown by the dotted line) diverges toward the outside of the reflector 1. In other words, by connecting the light blocking member 2 to different groups of adapter points 3, the vertical distance between the mounting hole 11 and the light blocking member 2 changes, which in turn causes the relative position of the light source and the light blocking member 2 to change, thereby changing the refraction path of the light emitted by the light source. The user can adjust the position of the light blocking member 2 according to different shooting requirements to adapt to different shooting scenes.

[0027] The above specific implementation methods are used to illustrate the present invention rather than to limit the present invention. Any modifications and changes made to the present invention within the spirit of the present invention and the protection scope of the claims shall fall within the protection scope of the present invention.
