Embodiment 1

[0026] Such as Figure 1 to Figure 4 As shown in , the fast-folding shading device described in Embodiment 1 of the present invention includes a funnel-shaped shading cover body 1, and the funnel-shaped shading cover body 1 is folded from a shading plate, and the shading plate is provided with The first folding mark 2 and the folding positioning member 3, and the through hole 4 coaxial with the funnel-shaped shade body 1 . Wherein, the funnel-shaped shade body 1 may be a polyhedral funnel shade body, including a connected bottom plate 7 and several side plates 8, such as figure 1 and 2 , the funnel-shaped shading cover body 1 is a square funnel shading cover, including a connected bottom plate 7 and more than four side plates 8, the side plates 8 are trapezoidal plates; the middle of the bottom plate 7 is provided with a through hole 4 , several side plates 8 are arranged around the bottom plate 7 in a circular distribution, and the first folding marks 2 are provided between...

Embodiment 2

[0032] Such as Figure 5 As shown in , the fast-folding shading device described in Embodiment 2 of the present invention is basically the same in structure as Embodiment 1, including a funnel-shaped shading cover body 1, which is formed by folding a shading plate. As a result, the first folding mark 2 and the folding positioning part 3 are provided on the sunshade plate, as well as a through hole 4 coaxial with the funnel-shaped shade body 1 . The only difference is that the funnel-shaped shading cover body 1 is a circular funnel shading cover body, including a connected bottom plate 7 and more than two arc-shaped side plates 8, and the bottom plate 7 and the side plates 8 are respectively circular. The bottom plate and the arc-shaped side plates can be specifically: the circular funnel shading cover body includes two arc-shaped side plates on the left and right, and the two arc-shaped side plates on the left and right are symmetrically arranged on the circular bottom plate ...

Abstract

The invention relates to a shading device capable of being quickly folded. The shading device comprises a funnel-shaped shading cover body. The funnel-shaped shading cover body is formed by folding ashading plate. The shading plate is provided with a first folding mark, a folding positioning piece and a through hole coaxial with the funnel-shaped shading cover body. The shading device can be unfolded into a plane shape when not used; the size and occupied space are greatly reduced; the device is light in weight, and is easy to store and carry; and the shading device is very simple in structure, is easy in production and processing, is obviously reduced in cost, facilitates mass production, is extremely easily accepted and loved by photographic fans, is extremely high in market competitiveness and and is extremely good in market prospect.

Description

technical field [0001] The invention belongs to the technical field of photographic equipment, in particular to a fast-folding shading device. Background technique [0002] In taking pictures and photography, the shading device is often used to be installed on the camera lens or on the camera lens (for example: camera hood, film shading bucket). However, the applicant found that the existing shading devices on the market are all made of aluminum and other metals or plastics, which are very heavy and fixed in shape and cannot be folded. Therefore, they are large in size and occupy a large space, and are extremely inconvenient to store and carry. , and the structure is very complex, the production process is difficult and the cost is high. [0003] In addition, when the filter frame is installed on the camera lens and the camera lens, neither the existing camera matte box nor the film matte box can be installed and used, and cannot meet the needs of photography.
