Abstract

The invention provides a folding frame screen which comprises a screen frame, screen cloth arranged on a plane formed by surrounding of the screen frame, and bases arranged at the bottom of the screen frame. A detachable connecting portion is arranged in the screen frame, a first base and a second base are detachably connected with the screen frame, the first base or the second base comprises a main rod, a first auxiliary rod, a second auxiliary rod and a third auxiliary rod, a plane formed by surrounding of the main rod, the first auxiliary rod and the second auxiliary rod is perpendicular to a plane where the screen frame is positioned, and two ends of the third auxiliary rod are connected with the main rod and a second cross rod respectively. The folding frame screen is more convenient and quicker to assemble and disassemble, saving of space and material and high in wind resistance.

Description

technical field [0001] The invention relates to the field of outdoor screens, in particular to a folding frame screen. Background technique [0002] As an outdoor projection equipment, the outdoor screen is a screen for projecting enlarged film images. Originally made of white cloth. Later, diffuse reflection screens made of cloth or plastic coated with barium sulfate or metal powder are often used. There are also reflective screens made of glass bead paint, and transmissive screens made of translucent materials. Due to the particularity of the outdoor environment, outdoor screens often need to have the function of resisting certain wind, rain and snow. [0003] Outdoor screens are generally larger in size, so their portability is often the focus of attention. In the prior art, outdoor screens are generally assembled in a detachable manner. However, the disassembly and assembly takes a long time, the service life is short, and there is room for improvement in wind resist...
