Embodiment Construction

[0033] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0034] Such as figure 1 , figure 2 and image 3 As shown, the projection screen storage device includes a support rod 1, a leg 2, a curtain hook 3 and a curtain storage bucket 5, the curtain 4 is folded in the screen storage bucket 5, and the support leg 2 is installed on the bottom of the support rod 1, and the support leg 2 It can also be stored (not shown in the drawings), and the curtain hook 3 is installed on the top of the support rod 1 . The curtain storage bucket 5 is installed on the support rod 1 through an adjustment mechanism, and the adjustment mechanism includes a connecting shaft 6, a slider 7 and a locking bolt 8, and one end of the connecting shaft 6 is rotatably connected with the curtain storage bucket 5 (can be 360 °...

Abstract

The invention discloses a projection screen storage apparatus and a use method therefor. One end of a connecting shaft (6) is rotationally connected with a screen storage bucket (5), and the other end of the connecting shaft is fixedly connected with a sliding block (7); a locking bolt (8) penetrates through the sliding block (7) and props against the outer wall of a supporting rod (1); an engagement part (9) is arranged on the lower surface of a screen hook (3); an engagement matching part (10) is arranged at the end part of the screen storage bucket (5); and the position of a limiting ring (13) ensures that the end part of the screen storage bucket (5) just props against the lower surface of the screen hook (3) when the sliding block (7) props against the limiting ring (13). According to the apparatus and the method, during storage, the engagement part is engaged in the engagement matching part, so that the storage bucket can be fixed and difficultly swings, and the fixing effect is good; the screen hook has two effects of fixing the storage bucket during storage and suspending screen during use simultaneously; and the design is novel, a separate storage bucket fixing mechanism is removed, and the structure is simple.

Description

technical field [0001] The invention relates to a projection screen storage device and a usage method thereof.
