Description
Technical field
The utility model belongs to projection screen field, particularly relates to a kind of portable translucent screen.
Background technology
Along with the development of shadow casting technique, projector is miniaturization more and more, also more easily carries, but projection screen supporting with it does not improve, because old-fashioned projection screen volume is large, heavy, cause carrying and inconvenience, had a strong impact on the outdoor use of projector.
Summary of the invention
In order to solve the shortcomings such as the large heavy of projection screen volume, the utility model is to provide a kind of portable translucent screen.
Portable translucent screen, comprises down fixing rack, curtain support bar, curtain room, curtain spool, spring, curtain chamber cap, spring lever, curtain, curtain spool connector.Owing to volumetric contraction to very little, can carry easily.
Wherein, the two ends of curtain are wrapped on two curtain spools respectively, and when curtain trails, curtain spool follows rotation together with spring, make curtain have the torsion reclaimed because spring rotates the torsion produced, this torsion can realize curtain automatic winding on curtain spool.
Wherein, two described curtain support bars, act as after curtain launches, because the effect that curtain is subject to spring force makes curtain to shrink, curtain support bar plays the recovery stoping curtain.Two curtain support bars when curtain launches, can adjust its length and angle simultaneously, after curtain is deployed into appropriate length, tighten coupling shaft locking knob, so just can fix the state of curtain.
Wherein, curtain spool can rotate in curtain indoor, and curtain is the used time not, and can loosen the coupling shaft locking knob on curtain support bar, curtain is subject to spring force, and automatic winding is on the curtain spool of curtain indoor.
Wherein, liftable fixed mount is made up of two support bars and two adjuster bars respectively, and is fixed on the outside of curtain room by upper support adapter and lower support regulator.Upper support adapter and lower support regulator can slide up and down in the outside of curtain room, are slided up and down height and the angle of i.e. adjustable down fixing rack by it.By regulating the height of liftable fixed mount, can realize the adjustment of curtain overhead height, the angle of adjustment fixed mount, can adjust the stability of full screen for different external environment condition.
Wherein, upper support adapter and lower support regulator have locking knob, after the height adjusting down fixing rack and angle, tighten locking knob, down fixing rack position just can be made to be fixed up.
Wherein, foot-operated head is connected to the lower end of support bar, when open air use, can tramp with one's feet on foot-operated head, and support bar can be deep in earth.

Embodiment
For making object of the present disclosure, technical scheme and advantage clearly understand, below in conjunction with embodiment and accompanying drawing, the disclosure is described in further detail.At this, exemplary embodiment of the present disclosure and illustrating for explaining the disclosure, but not as to restriction of the present disclosure.Below combine accompanying drawing to be described in detail to the disclosure.
In the present embodiment, state when portable translucent screen is turned up, as shown in Figure 1: now curtain 8 is wrapped on curtain spool 4 by spring force, and is in curtain room 3 (with reference to figure 6); Curtain support bar 2, by its Telescopic, can be folded up; Upper support adapter 11 in down fixing rack 1 and lower support regulator 12 can slide in the water jacket of curtain room 3, slide into the upper end of curtain room 3 when turning up.State of turning up like this takes up room little, compact between parts, can realize its portable functional.
In the present embodiment, state when portable translucent screen launches, as shown in Figure 2: portable translucent screen transfers in deployed condition by the state of turning up, first open the locking knob 13 on upper and lower two curtain support bars 2, make curtain support bar 2 freely to stretch and to adjust angle; Two curtain rooms 3 separately, curtain 8 can be followed curtain room 3 and be launched, and in the middle of process, curtain spool 4 makes spring be subject to torsion by rotation simultaneously; After curtain 8 is deployed into suitable width, tighten the locking knob 13 on curtain support bar 2, avoid curtain 8 be subject to spring torsion and shrink back; Open the locking knob 13 on down fixing rack 1, make support adapter 11 and lower support regulator 12 can carry out slip adjustment along curtain room 3, after down fixing rack 1 adjusts height and angle, tighten locking knob 13, at this moment down fixing rack 1 is in stationary state.Launch completely to this whole portable translucent screen and can use.Fig. 3 is the schematic diagram after portable translucent screen height regulates.
In the present embodiment, the structural drawing of curtain support bar as shown in Figure 4: support outer tubes 22, two by two and support inner sleeves 24, support and connection 21, stay pipe snap close 23, support and connection axle 25 and coupling shaft locking knob 26 and form; Support inner sleeve 24 to slide in support outer tube 22, because the non-circular design of itself, make to support inner sleeve 24 to slide along a direction, such design is in order to curtain 8 is when turning up, and upper and lower two curtain support bars 2 can not collided mutually when screen is turned up; Support outer tube 22 and support between inner sleeve 24 and have a stay pipe snap close 23, a coupling shaft locking knob 26 is had between support and connection axle 25, loosen stay pipe snap close 23 and coupling shaft locking knob 26 in the process that curtain 8 launches and turns up, curtain 8 tightens stay pipe snap close 23 and coupling shaft locking knob 26 after turning up and having launched.The support and connection at curtain support bar 2 two ends 21 are connected with curtain chamber cap 6.
In the present embodiment, down fixing rack 1 composition diagram, as shown in Figure 5, is made up of two support bars, 15, two adjuster bars 14, upper support adapter 11, lower support regulator 12, locking knob 13 and foot-operated 16.Two support bars 15 are fixed in support adapter 11, and two adjuster bars 15 are fixed on lower support regulator 12, and support bar 15 and adjuster bar 14 are linked together by axle.When needing the angle regulating curtain 8 height overhead and support bar 15 with ground, loosen the locking knob 13 of upper support adapter 11 and lower support regulator 12.By upper support adapter 11 and the lower support regulator 12 of sliding, change the position between itself and curtain room 3, i.e. adjustable curtain 8 height overhead and the angle on support bar 15 and ground.The adjustment of down fixing rack 1 is completed to this.
In the present embodiment, as shown in Figure 5: the connection of the upper support adapter 11 in down fixing rack 1 and lower support regulator 12 and curtain room 3, a concave groove is had outside curtain room 3, upper support adapter 11 and lower support regulator 12 respectively with the groove fit of curtain room 3, support adapter 11 and lower support regulator 12 are slided along groove, ensures the correct of its direction.
In the present embodiment, foot-operated 16 is connected to below support bar 15, and during outdoor use portable screen, in order to increase its stability, because support bar 15 lower end adopts acute angle design, firmly pin steps on foot-operated 16, and support bar 15 lower end can be made to be deep in earth.
In the present embodiment, as shown in Figure 6, curtain room 3, curtain chamber cap 6, spring lever 7, spring connector 9 are combined.Spring 5 and curtain spool 4 are fixed together by spring connector 9; One of spring 5 is stuck in spring lever 7, and one is fixed on spring connector 9, and spring lever 7 is fixed on curtain chamber cap 6; Curtain spool 4 freely can rotate in the groove of curtain chamber cap 6.When curtain 8 launches, curtain spool 4 can follow rotation, and now spring 5 is also followed and rotated and can produce a spring torsion, and when curtain 8 all launches, the torsion of spring 5 is maximum.When this structural design can make curtain 8 launch, be subject to a convergent force all the time, ensure that curtain 8 is open and flat; If when reclaiming, also can automatically shrink curtain 8, more convenient operation.
In this enforcement, as shown in Figure 7, on curtain chamber cap 6, the rope fixed orifice of band, under meeting landscape condition, can use rope to be fixed, make curtain more stable.
