Description

Technical Field

[0001] The utility model belongs to the field of auxiliary tools for photography or taking photos, and in particular relates to a combined background cloth supporting device. Background Art

[0002] In conference venues, photo studios and photography locations, a corresponding background is required, which is completed by installing a background cloth on a background frame. Existing background frames or curtain frames are usually composed of a crossbar assembly and two support seat assemblies connected to the left and right ends of the crossbar assembly to support the crossbar assembly, such as a background cloth frame disclosed in CN201921760626.7, a stable supporting background frame disclosed in CN202122367402.3, and a combined curtain frame disclosed in CN202321228875.8.

[0003] Specifically, in the aforementioned public patent, CN202321228875.8 supports the curtain by setting two support seat assemblies, and adopts an adjustable height support frame assembly and a retractable cross bar assembly, which can be adjusted accordingly according to curtains of different heights and lengths, but the length adjustment range of the cross bar assembly is small. When the length of the curtain is large, the combination of two support frame assemblies and one cross bar assembly cannot be applied, and it is also impossible to combine more support seat assemblies and cross bar assemblies to support the curtain. Utility Model Content

[0004] The utility model aims to solve the technical problems existing in the prior art, and the purpose of the utility model is to provide a combined background cloth supporting device.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a combined background cloth supporting device, comprising a plurality of supporting frames arranged in sequence along the length direction, and a plurality of cross bars arranged between two adjacent supporting frames, a first connecting piece is provided at both ends of the cross bar, a second connecting piece is provided on the top of the supporting frame, and the first connecting piece can be detachably connected to the corresponding second connecting piece; a fixing piece for fixing the background cloth is provided on the cross bar, and the background cloth can be hung on the front side of the cross bar through the fixing piece.

[0006] In the above technical solution, the supporting device is a combined structure composed of multiple supporting frames and multiple cross bars. By changing the number of supporting frames and cross bars, the length of the supporting device can be adjusted to adapt to background cloths of different lengths. The longer the background cloth is, the more supporting frames and cross bars are needed to ensure stability.

[0007] In a preferred embodiment of the present invention, the first connecting member is a movable lock buckle provided at the end of the cross bar, and the second connecting member is a hanging ring provided at the top of the support frame, and the movable lock buckle can be hooked on the hanging ring.
