The invention discloses an adjustable folding mobile film projection screen, which comprises a mounting base, wherein the mounting base is provided with a mobile wheel capable of being fixed; the mounting base is provided with a box body capable of rotating or swinging back and forth and left and right; a whole fixed plate capable of being fixed and spliced into a whole is arranged in the box body; the whole fixed plate comprises two upper and lower mother fixed plates and a plurality of child fixed plates; the mother fixed plates and the child fixed plates are sequentially connected into the whole fixed plate through fixing parts; and a screen is fixed on the outer side surface of the whole fixed plate; and the mother fixed plate at the lower end is fixed in the box body. The adjustable folding mobile film projection screen is clever and reasonable in structural design, contracting and releasing of the screen can be achieved by adopting the structure capable of being spliced, the design is novel, the influence of wind power on film projection of the screen can be effectively avoided, and the adjustable folding mobile film projection screen can be adjusted for use according to the actual operating environment and condition after being installed.
Description
[0001] Technical field: [0002] The invention relates to the field of screen design, in particular to an adjustable folding mobile projection screen. [0003] Background technique: [0004] The screen is a white screen used for projection and magnification when showing movies and slides. It has the advantages of soft light and no glare. [0005] However, the existing screen structures are all used by reeling and unwinding, and some are directly exposed to the air, which is easy to absorb dust and cause pollution; and when the general screen is used outdoors, it will be disturbed by the wind and affect the use. Effect; After installation, it is usually impossible to realize mobile adjustment through its own functions, and it is troublesome to use. [0006] Invention content: [0007] The object of the present invention is to provide an adjustable folding mobile projection screen in order to solve the deficiencies of the prior art. [0008] The technical scheme adopted in the...
