Embodiment
Below, embodiment of the present utility model is will be explained in, the example is shown in the accompanying drawings and the description below.Although will
The utility model is described with reference to exemplary embodiment, it is to be understood that the description does not really want the utility model to be limited to this to show
The embodiment of example property.On the contrary, the utility model will not only cover the exemplary embodiment, but also cover various replacements,
Change, equivalent and other embodiment, it can be included in spirit of the present utility model and the model that appended claims are limited
In enclosing.
As shown in accompanying drawing 1 to accompanying drawing 6：
The utility model provides a kind of technical scheme：A kind of computer teaching portable translucent screen, including plastics base
Body 1, cylindrical hole 2, screen storage tank 3, positioning sucker disk 4, hook 5, plastics locating shaft 6, locating shaft sucker 7, curtain 8 and on
Lid 9, the top of plastic substrate 1 offer screen storage tank 3；Cylindrical hole 2 extends through plastic substrate 1 and is opened in plastics base
On the outer wall of the left and right sides of body 1；Positioning sucker disk 4 is screwed to the back of plastic substrate 1；Hook 5 is screwed to plastics base
Inside the screwed hole being provided with body 1；Plastics locating shaft 6 is disposed through the inside of cylindrical hole 2；Locating shaft sucker 7 with
Locating shaft 6, which is screwed, to be connected；The top of curtain 8 offers positioning hole with end；Upper lid 9 is placed in screen storage tank 3
Top.
Specifically, positioning sucker disk 4 is provided with everywhere, plastic substrate 1 can be adsorbed in any smooth put down by positioning sucker disk 4
Face, facilitate installing and using for projection screen；
Specifically, the left and right ends of plastics locating shaft 6 are provided with screwed hole, locating shaft sucker 7 is screwed to plastics
