The present invention belongs to the technical field of photographic and videographic accessories, and in particular relates to a multi-directional stretching curtain.
With the progress of society and the improvement of people's living standards, people's requirements for quality of life are gradually increasing. As film, television and multimedia are gradually mature and stable, with the continuous innovation of mobile phone photography and the continuous improvement of people's requirements for image quality, image processing and video production have gradually become popular and are available for the general public. Image and video processing and production require a large amount of keying technology, so the premise of keying technology is to use a green background when shooting. However, in the past, the use of green background was mostly achieved by hanging a simple green cloth on the wall, which was not easy to carry and install, so it had certain limitations in use. At present, only one vertical surface of the retractable, integrated and foldable curtains on the market can be retracted in the shell, so objects on the ground cannot be completely covered by the curtain background during use. Since the curtain can be stretched only in one direction in the prior art, such curtain can only provide the scene of the back cloth and cannot provide the background of the ground because part of the objects will be located outside the curtain. Therefore, it is very important to urgently obtain a multi-directional stretching curtain that overcomes the above defects.
In order to solve at least one of the above technical problems, the present invention provides a multi-directional stretching curtain which includes a box body, where at least one first curtain body and at least one second curtain body are provided in the box body; the first curtain body includes a first rotating shaft and at least one first curtain wound on the first rotating shaft; and the second curtain body includes a second rotating shaft and at least one second curtain wound on the second rotating shaft, and the first curtain and the second curtain are pulled out in different directions, and at least partially overlap or are connected to form a complete background at least from a certain visual angle.
As a preferred embodiment of the above technical solution, the box body is provided with an opening, preferably one opening is provided, both the first curtain and the second curtain are pulled out from the opening, and the first curtain and the second curtain are stretched outward from the opening; both ends of the first rotating shaft are matched with an inner wall of the box body so that the first rotating shaft is at least partially rotatable; and both ends of the second rotating shaft are matched with the inner wall of the box body so that the second rotating shaft is at least partially rotatable.
With the technical solution described above, since only one opening is provided, and both curtains are pulled out from the opening, there is no visual field blocking between the curtains.
As a preferred embodiment of the above technical solution, the first curtain is drawn out to form a floor cloth extending in a first direction, and the second curtain is drawn out to form a back cloth extending in a second direction.
As a preferred embodiment of the above technical solution, a second support rod is provided at an end portion of the second curtain, and a telescopic assembly is provided between the second support rod and the box body.

Here, a first telescopic rod is hinged between the first hinge and the fifth hinge, and a second telescopic rod is hinged between the second hinge and the sixth hinge.
Preferably, an axis of the second rotating shaft is lower than an axis of the first rotating shaft in order to increase the visual angle of completely presenting the background.
Here, a first support rod is provided at an end portion of the first curtain to pull out the first curtain flat.
As a preferred embodiment of the above technical solution, at least one roller is provided in the box body, and at least part of the roller penetrates from an outer wall of the box body to the outside; and at least one perforation is provided on the box body, opposite bracket members are mounted in the box body, a rotating shaft is provided between the two bracket members, and a roller is provided on the rotating shaft.
A lifting handle is provided on the box body. The lifting handle is hinged to the box body.
The roller is at least partially exposed from a side wall of the box body, and the roller at least partially penetrates from a bottom portion of the box body. It is aimed to increase the smoothness of pulling the box body horizontally and obliquely.
The multi-directional stretching curtain further includes a cover body matched with the box body, at least one step groove is provided on the cover body, and a step protrusion matched with the step groove is provided on the box body.
With the technical solution described above, a lock catch is further provided between the cover body and the box body.
Compared with the prior art, the present invention has the advantages that the present invention has a simple structure, and the two-way telescopic, integrated and foldable curtain covering the floor solves the problem that the floor portion at the bottom of the objects being photographed cannot be covered as a background.
