Accompanying drawing explanation
Fig. 1 is the structural representation of projection screen of the present invention;
Fig. 2 is the structural representation of the first connected structure of the present invention and the second connected structure.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail, can implement according to this with reference to instructions word to make those skilled in the art.
As depicted in figs. 1 and 2, the invention provides a kind of assemblnig projection screen, each unit 1 comprises: collecting assembly 2, and it is hollow tube-shape, and bottom has opening; Reel assembly, it is arranged on the inside of described collecting assembly 2 rotationally; Curtain component 3, it is wound on described reel assembly; When multiple unit 1 is assembled, the collecting assembly 2 of adjacent two unit is linked together by the first connected structure, reel assembly is linked together by the second connected structure, curtain component 3 is linked together by link 4, the collecting assembly of multiple unit, reel assembly are connected successively with curtain component, the open communication of the collecting assembly of multiple unit becomes a curtain outlet, thus forms collecting component, spool and curtain; The reel assembly of one of them unit is also connected to a motor, and after multiple unit assembling, described motor drives described spool to rotate, and is stretched out to make described curtain and is launched by described curtain outlet.
As shown in Figure 2, the collecting assembly of adjacent two unit is linked together by the first connected structure, specifically, in described assemblnig projection screen, described first connected structure comprises the first projection 8 of the ring-type of end 6 outside surface of the collecting assembly being arranged on one of them unit and is arranged on first groove of ring-type of end 7 inside surface of collecting assembly of another unit, and the external diameter of the end 6 of the collecting assembly of one of them unit equals the internal diameter of the end 7 of the collecting assembly of another unit, the end 6 of the collecting assembly of one of them unit is inserted into the inside of the end 7 of the collecting assembly of another unit, and the first projection 8 is fastened in the first groove.After the end of the collecting assembly of one of them unit is inserted into the inside of the end of the collecting assembly of another unit, both restrictions also depart from by friction between two ends each other.The structure of above-mentioned first connected structure is simple, easy to use.
In described assemblnig projection screen, described second connected structure comprises the second projection 10 and the second groove, described second projection 10 is arranged on the outside surface of the end 9 of the reel assembly of one of them unit, extend internally vertically by the end of the end 11 of the reel assembly of one of them unit, the end 11 of the reel assembly of another unit offers columniform 3rd groove, described second groove is arranged on the wall of the 3rd groove, the external diameter of the end 9 of the reel assembly of one of them unit equals the internal diameter of the 3rd groove of another unit, the end 9 of the reel assembly of one of them unit is inserted in the 3rd groove of another unit, second projection 10 snaps in the second groove.After multiple reel assembly is in turn connected into a complete spool, in order to prevent, in rotary course, relative rotation occurs between reel unit, the second projection of the second connected structure is designed to extend vertically.In addition, after the end of the reel assembly of one of them unit is inserted into the inside of the 3rd groove of another unit, friction between the end of the reel assembly of one of them unit and the 3rd groove of another unit also limits the two and departs from each other, thus ensures being connected firmly of two reel units.
In described assemblnig projection screen, described link comprises slide fastener, and a pair chain denture be engaged with each other of described slide fastener is separately positioned on the marginal portion of the vertical extension of the curtain of adjacent two unit.Above-mentioned slide fastener can select plastic material, to reduce the impact on drop shadow effect.
In order to reduce the impact of slide fastener on projected picture further, in described assemblnig projection screen, arbitrary curtain is also provided with the covering portion in the outside covering a row chain denture in the marginal portion of each vertical extension, and described covering portion is consistent with the material of this curtain.
In described assemblnig projection screen, described multiple unit comprises three unit.
The present invention can also comprise some independent curtain unit, curtain unit is square, four marginal portions of curtain unit are provided with chain denture, when needing in the vertical direction to increase the width of screen, just connect a curtain unit again in the below of the curtain component of aforesaid each unit.
Although embodiment of the present invention are open as above, but it is not restricted to listed in instructions and embodiment utilization, it can be applied to various applicable the field of the invention completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the present invention is not limited to specific details and illustrates here and the legend described.
