The translucent screen with the frame structure has the advantages that the translucent screen is simple and convenient in fold and unfold; the structure is firm, so the projection quality is excellent; and simultaneously, the screen is easy to disassemble, and is convenient to be moved to different positions for use and also convenient to disassemble for cleaning or storage when not used.
Description
Technical field
The utility model relates to a kind of projection screen, relates in particular to a kind of projection screen of framed structure.
Background technology
Along with the application of projector is more and more universal, projection screen needs varying environment to use now.That now general projection screen adopts or be the structure that curtain is fixed in framework, or adopt the structure of spool folding and unfolding curtain.If adopt the fixedly structure of curtain, advantage is the curtain firm stable, and it is less that curtain is influenced by external environment such as for example wind, and the quality of projection is better; Shortcoming is can't the folding and unfolding curtain, will cause a lot of inconvenience like this, and for example inconvenience is moved, and is not easy to again obsolete the time curtain be cleaned or preserves simultaneously.The advantage of the structure of folding and unfolding curtain is, and is easy to use, is convenient to move, be convenient to again without the time collection protection curtain; Shortcoming is that structure is unstable, and curtain is affected by the external environment easily and is subjected to displacement in the time of projection, thereby influences project effect.
The utility model content
The technical problems to be solved in the utility model is how to provide a kind of curtain folding and unfolding convenient well-set again projection screen simultaneously.
In order to solve the problems of the technologies described above, the utility model designs a kind of projection screen of framed structure, comprise: the outside framework of rectangle and the curtain that is installed in this outside framework, described curtain is connected with the curtain axle that extends along this end at least two symmetrical ends, have the housing groove that is used to hold the curtain axle in the inboard of described outside framework;
The projection screen of described framed structure also comprises: at least two active card are connected to described outside framework, are used to seal the housing screens of described housing groove.
By technique scheme, can be positioned over the curtain axle in the housing groove, be connected on the outside framework sealing housing groove with fixing curtain axle with housing screens active card then, with this whole curtain is fixed in the outside framework.And housing screens and outside framework are the activity clampings, can take off the housing screens from outside framework very easily, and curtain also takes out from outside framework very easily.
As the utility model embodiment more specifically, the position in the inboard of described outside framework near the housing groove has the housing raised line that parallels with the housing groove;
Described housing screens comprises: be used to engage the engaging folder of the described housing raised line of clamping, and the blind end that is used to seal described housing groove.
Described engaging folder comprises: be arranged on the clamping face, cooperate the last clamping part and the following clamping part that form the folder shape;
Described down clamping part is a projection that is arranged in the middle of the clamping face bottom, and the described clamping part of going up is to be arranged on being separated from each other and being parallel to described two projections of clamping part down of clamping face top.
In order further to promote the close and firm degree of housing screens and the clamping of outside framework, described engaging folder comprises, is arranged on the screens double wedge partly that contacts with described housing raised line.
In order further to promote the firmness that curtain cooperates with outside framework, described end on described curtain four limits all has the curtain axle that prolongs this end extension, and is corresponding in this, all has the housing groove that is used to hold the curtain axle in the inboard on four limits of described outside framework.
As curtain and concrete connected mode of curtain axle, the end of described curtain has a curtain axle sleeve, is used for inserting the described curtain axle of placement.
Described outside framework is that hollow section bar constitutes.To conveniently make installation like this, can easily the section bar connection be combined into outside framework by the web member that inserts in the section bar, and intensity height, in light weight.
In order further to promote the firm degree of outside framework, prevent the outside framework distortion, described outside framework also comprises, is arranged on housing frame-saw inside, is supported in the housing support bar of the opposite end of outside framework.
Compared with prior art, advantage of the present utility model is that the projection screen folding and unfolding is easy, and sound construction, so projection quality is also outstanding; Simultaneously be easy to pull down curtain again, therefore be convenient to move to diverse location and use, also be convenient to obsolete the time, pull down curtain and clean or preserve.
