Embodiment
With the following Examples the utility model is further described.
A kind of flat-open type support projection screen of the present utility model, extremely shown in Figure 5 as Fig. 1, include outer cover 1, spool, curtain 2, support bar 3 and leg 4, outer cover 1 comprises left outer cover 11 and right outer cover 12, right outer cover 12 or left outer cover 11 are provided with spool, spool is provided with torsion spring, corresponding curtain 2 one ends are fixed in left outer cover 11 or the right outer cover 12, the other end is wrapped in spool by torsion spring torsion, during use, horizontal opening left side outer cover 11, right outer cover 12, curtain 2 is drawn out from spool, close up left outer cover 11 when not using, right outer cover 12, curtain 2 is retracted in the outer cover 1 by the torsion of torsion spring.Leg 4 is connected with support bar 3, can open during use to be supported on the ground, can merge gathering when not using.
In the present embodiment, be provided with the telescoping mechanism of a support curtain 2, telescoping mechanism comprises support 5 and slide block 7 and is arranged at chute 6 in the outer cover 1, fixedly connected with outer cover 1 in support 5 upper ends, the bottom is connected with slide block 7, perhaps fixedly connected with outer cover in support 5 bottoms, and the upper end is connected with slide block, slide block 7 and chute 6 sliding connections.
Concrete, it is hinged that support 5 includes first support 51 and second support, 52, the first supports 51 and second support 52, overlaps mutually to constitute " X " shape support, be positioned at first support 51 and second support, 52 mutual junctions and be " X " shape articulated structure, hinge is perpendicular to the plane at curtain 2 places.Thereby first support 51 and second support 52 can freely be rotated around hinge.
Use said structure, when carrying out projection, open left outer cover 11, right outer cover 12, torsion spring in the outer cover 1 shrinks, slide block 7 slides along the chute in the outer cover 16, and torsion spring shrinks that telescoping mechanism is opened with outer cover 1 and horizontal stretch, thereby curtain 2 is drawn out to required length from spool; When not using projection, close up left outer cover 11, right outer cover 12, it is overlapped and close up that telescoping mechanism is compressed into first support 51 and second support 52.Therefore, whole process operation is simple, has dwindled spatial volume greatly after outer cover closes and closes, and is easy to carry very much.
Further, described left outer cover 11 and right outer cover 12 are respectively arranged with draw-in groove 8 and the buckle 9 that is complementary, when not using projection, left side outer cover 11, right outer cover 12 close up, described draw-in groove 8 and buckle 9 clampings, thus outer cover 1 is fastened, and telescoping mechanism 5 is contained in the closed outer cover 1, save the space, be convenient for carrying.
A kind of flat-open type support projection screen of the present utility model, to shown in Figure 5, in the present embodiment, support bar 3 inside are provided with expansion link 31 as Fig. 1, and extension and the described support 5 that stretch out the expansion link 31 of support bar 3 are connected by stationary shaft.This expansion link 31 optional position in telescopic process can be blocked by clamping part, and expansion link 31 tops are provided with handle 311, thereby can adjust the required height that reaches of curtain by 311 length of adjusting expansion link 31 of shaking hands.
In the present embodiment, leg 4 is connected with support bar 3 by a sliding sleeve 41, and sliding sleeve 41 is sheathed on described support bar 3, and described leg can adopt two joint retractor devices.During use, open leg 4 and be supported in ground, when not using, it can be merged and draw in.
Support bar is provided with handle 10, can be used for portably using.
Fig. 1 and Fig. 3 have showed the user mode of a kind of flat-open type support projection screen of the present utility model and the structural representation of collapse state respectively, and its principle of work is as follows:
When carrying out the projection use, leg 4 opened stand on ground, open left outer cover 11, right outer cover 12, the torsion spring of spool shrinks, slide block 7 slides and stressed in torsion spring along the chute in the outer cover 16, and support 5 shrinks with outer cover 1 by torsion spring to be opened and horizontal stretch, thereby curtain 2 is drawn out to required length from spool, the length of pulling handle 311 adjustment expansion links 31 makes curtain 2 reach required height then, can carry out projection;
When not using projection, because the state of nature of torsion spring and curtain are corresponding when opening, and close up left outer cover 11, right outer cover 12, it is overlapped and close up that support 5 is compressed into first support 51 and second support 52, reach equilibrium of forces, curtain 2 is retracted in the outer cover 1 by the torsion of torsion spring.A left side outer cover 11, right outer cover 12 close and close, thereby the draw-in groove of outer cover 18 is fastened outer cover 1 with buckle 9 clampings, and telescoping mechanism are contained in close in the outer cover 1 that closes.Then, expansion link 31 is retracted to downwards in the support bar 3, close up leg 4 after, integral body is portability.
Should be noted that at last; above embodiment is only in order to the explanation the technical solution of the utility model; but not to the restriction of the utility model protection domain; although the utility model has been done detailed description with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the essence and the scope of technical solutions of the utility model.
