Description

Technical Field

[0001] The present application relates to the technical field of background frames, and in particular to a background frame for studio photography. Background Art

[0002] Background cloths play a vital role in photography, stage performances, and interior decoration. Not only are they essential for indoor photography, providing a monochrome or thematic backdrop, but they also help photographers better control their shots by varying the background's color and style. In photography, choosing background cloths in simple colors like gray, black, and white makes it easier to control light and shadow, resulting in better results. Background cloths can also provide shielding and isolation, protecting privacy or isolating distractions like noise, ensuring a pure and focused shooting or performance environment.

[0003] When using the background cloth, it needs to be set up by a supporting device. Most of the existing background cloth brackets are adjusted in length by a rolling structure, but the background cloths they are suitable for are of fixed size. When the background cloth needs to be replaced in actual use, the existing background brackets are very cumbersome to use, and the existing background cloth brackets are not universal. Utility Model Content

[0004] Based on this, it is necessary to provide a studio photography background stand to address the problem that the background stand for traditional background cloths is not suitable for background cloths of different sizes, resulting in the background cloth stand not having universal applicability.

[0005] The present application provides a studio photography background frame, comprising:

[0006] a first support frame;

[0007] a second support frame, disposed on one side of the first support frame, the first support frame and the second support frame being disposed parallel to each other, and the structure of the first support frame is the same as that of the second support frame;

[0008] a first positioning rod, disposed between the first support frame and the second support frame, wherein one end of the first positioning rod is fixedly connected to the first support frame, and the other end of the first positioning rod is fixedly connected to the second support frame;

[0009] a second positioning rod, disposed between the first support frame and the second support frame, the second positioning rod being disposed on the top of the first positioning rod, one end of the second positioning rod being slidably connected to the first support frame, and the other end of the second positioning rod being slidably connected to the second support frame;

[0010] a first driving member, disposed on the first supporting frame, and configured to drive one end of the second positioning rod to move;

[0011] a second driving member, disposed on the second support frame, for driving the other end of the second positioning rod to move, wherein the structure of the first driving member is the same as that of the second driving member;

[0012] A plurality of first positioning members are provided, and each of the plurality of first positioning members is slidably sleeved on the first positioning rod;

[0013] The second positioning members are provided in plurality, and the plurality of second positioning members are all slidably sleeved on the second positioning rod.

[0014] The present application relates to a studio photography background stand, which drives both ends of a second positioning rod to move synchronously by simultaneously starting a first driving member and a second driving member, and drives the second positioning rod to move toward a predetermined position in a direction close to the first positioning rod, then fixes one end of a background cloth by a plurality of second positioning members on the second positioning rod, and tightens the background cloth by adjusting the positions between the plurality of second positioning members, then synchronously starts the first driving member and the second driving member again to drive the second positioning rod to move toward a predetermined position in a direction away from the first positioning rod, fixes the other end of the background cloth by a plurality of first positioning members on the first positioning rod, and tightens the background cloth by adjusting the positions between the plurality of first positioning members.
