Shadow screen, i.e., a kind of foldable sound, video projection screen.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of foldable sound, video projection screen, including grip block and contiguous block, the grip block three is one group, folder
Block is held by hinge to be connected, one group of grip block can be folded into triangle, and contiguous block shares two, grip block share two groups and
Replace connection composition rectangle frame with two contiguous blocks, the screen of cloth is installed in rectangle frame, the centre bit on two contiguous blocks
Put and be respectively equipped with grapple and lock tube, grapple is engaged with lock tube, and cavity is provided with inside grip block, is put down between grip block by two
Capable hinge is connected, and rotating shaft is provided between hinge, and spring is cased with rotating shaft, and grip block top is provided with lid, two groups of grip blocks
Center be provided with the first round bar, the first round bar periphery is cased with the second round bar that can be slid along, set on the second round bar
There is adjusting screw, the second round bar bottom is provided with base.
The grip block and the connection fixed by snap of the first round bar, it is fixedly connected with the stability for keeping screen, Bu Huizhuan
Move or rock.
The spring is torque spring.Torque spring helps the screen after folding to be reduced into normal operating condition.
The spring is symmetrical by symmetrical centre of rotating shaft.
The cavity is rectangular, is used to install spring in cavity, while alleviate the weight of device.
The distance that first round bar can slide is 0~50cm, can adjust the height of screen.
Its operation principle is：When needing to fold up screen, screen is folded into triangular prism shape, grapple and lock tube phase
Coordinate and cause screen folds to be fixed up, then screen can be carried to other meeting rooms or change a position, screen takes empty
Between it is small, when needing to use screen, grapple and lock tube are untied, in the presence of torque spring, screen reverts to original state, use
It is convenient；The height of screen can be adjusted by adjusting screw, meets different to use needs.
The beneficial effects of the utility model are：The utility model has the advantages of using flexible and convenient in carrying, this projection
Screen can be folded up, and occupy little space, and be easy to carry；This projection screen is folded up when not in use can prevent screen quilt
Dust pollutes, and keeps the cleaning of screen；This projection screen height with lift adjustment, can meet the needs of different height.
