Embodiment
Below in conjunction with the accompanying drawings, one embodiment of the present invention is further described.
A kind of vertical projection screen, as shown in Fig. 1 ~ 4, including curtain 1, support bar 2, cross bar and base.In the left and right of curtain Both sides all connect a support bar 2;Described support bar 2, it is hollow circular-tube;The side of support bar is provided with the groove 3 of one of hollow out, The position of the groove 3 of left side support bar compare the right support bar groove 3 position it is high;The upper end hinge of the groove 3 of the support bar 2 on the left side A cross bar is connect, the lower section of groove is provided with the jack 4 of one;The lower end of the groove of the support bar 2 on the right is also hinged a cross bar, groove Top also is provided with a jack 4.In use, the other end for the cross bar being hinged on the support bar groove of the left side is inserted in the right support bar Jack 4 in, be hinged on the right support bar groove on cross bar the other end be inserted in the right support bar jack 4 in.
Described cross bar, it is made up of two pole, first segment pole 5a one end is hinged on the groove 3 of support tube, another End is provided with arc chute 6a, and the sub- 5b of the second pole one end is provided with axle 6b, for being connected to first segment pole 5a arc chutes 6a In, the sub- 5b of the second pole other end is used to be inserted in the jack 4 of another support bar.
Described base, provided with 2.Base includes the foundation 7 for connection support bar 2, fixed bottom plate 8 and movable floor 9, described movable floor 9 is hinged on fixed bottom plate 8, movable floor 9 is horizontally rotated.When movable floor 9 is gone to consolidating When determining the opposite direction of bottom plate 8, base Cheng " Shang " shape;When movable floor 9 is gone to it is overlapping with fixed bottom plate 8 when, base is in " L " Shape.The other end of movable floor 9 is additionally provided with feet 10.
Further, described foundation 7, its upper end are provided with jack 11;Described support bar 2, its lower end are provided with inserted link 12, use In the jack 11 being inserted on foundation 7.
During using above-mentioned embodiment, when erecting projection screen, first curtain 1 is opened completely, and takes out two branch successively Cross bar on strut 2 is simultaneously inserted on corresponding support bar in jack 4(Cross bar can strut curtain, make curtain more smooth);Then By on the inserted base of support bar 2.If by wall use, will work as movable floor 9 go to fixation bottom plate 8 it is overlapping, base is L-shaped ;If not leaning on wall, the direction opposite with fixed bottom plate 8, base Cheng " Shang will be gone to when movable floor 9 " shape.Pack up During projection screen, first support bar 2 is removed from base, refolding cross bar is placed it in support bar 2(As shown in Figure 5), so Afterwards by curtain volume 1 on support bar 2.
Embodiments described above, only it is the implementation example of the present invention;It will be apparent to those skilled in the art that do not taking off On the premise of from the principle of the invention, some made change, and should all be considered as belonging to protection scope of the present invention.
