Embodiment Construction

[0025] The frame structure projection screen that can reduce the transportation volume provided by the embodiment of the present invention includes a rectangular frame structure 10 and a screen 20 installed on the frame structure 10 .

[0026] Such as figure 1 and figure 2 As shown, the rectangular frame structure 10 is composed of a hollow profile, specifically assembled from four frames 11 through connectors inserted in the frames 11 . Among the four frames 11 , at least two opposite frames 11 are two-stage frames 12 . The two-section frame 12 is formed by connecting two half frames 13 through connecting bars 14 . Both ends of the connecting bar 14 are respectively inserted into the two half frames 13 . A row of threaded holes 15 are respectively provided at the connecting parts of the connecting strip 14 and the half frame 13 , which are fixed with screws 16 to form a complete two-stage frame 12 .

[0027] The length of the entire two-section frame 12 can be adjusted b...

Abstract

The invention relates to a projection screen, and discloses a projection screen with a frame structure and capable of reducing transport volume. The projection screen comprises an axisymmetric frame structure and a screen arranged at the frame structure; the frames of at least two symmetric sides of the frame structure are two-section frames which are convenient to assemble and disassemble; and the two-section frame is formed by connecting two half frames through a connection strip of which two ends are inserted into the two half frames. The projection screen with the frame structure has the advantages that: when the frame structure is disassembled to be transported, each two-section frame can be disassembled into two half frames, and the length of the half frame is greatly smaller than that of a whole frame, so that the projection screen with the frame structure is convenient to transport.

Description

【Technical field】 [0001] The invention relates to a projection screen, in particular to a frame structure projection screen, in particular to a frame structure projection screen which can reduce the transport volume. 【Background technique】 [0002] As the application of projectors becomes more and more popular, projection screens need to be used in different environments. Now the general projection screen adopts either that the screen is fixed to the frame structure, or the screen structure is retracted by a reel. The advantage of adopting retractable screen structure is that it is easy to use, easy to move, and convenient to store and protect the screen when not in use; the disadvantage is that the structure is relatively unstable, and the screen is easily displaced by the external environment during projection, thus affecting the projection effect. The advantage of using a fixed screen structure is that the screen is firm and stable, the screen is less affected by the ext...
