Specific embodiment

In the following, with reference to attached drawing and specific embodiment, the utility model is described further, it should be noted that Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new Embodiment.

Portable projector curtain frame as shown in Figs. 1-3, including stent and curtain 3, stent include main support rod 1 with And four support bars 2, one end of support bar 2 is hinged with the main support rod 1, which further includes moulding 4, One end of moulding 4 is connect with the other end of support bar 2, and the other end of the moulding 4 is connect with the other end of another support bar 2, frame Item 4 at least two is set according to 3 longitudinal direction of curtain, which is slidably connected with two longitudinally disposed mouldings 4, and two The distance between longitudinally disposed moulding 4 of item can be fully deployed the curtain 3.

It is hinged by one end and the main support rod 1 of support bar 2, so that support bar 2 can be according to the big of the curtain 3 It is small to adjust the distance between support bar 2, and because one end of moulding 4 is connect with the other end of support bar 2, moulding 4 it is another End is connect with the other end of another support bar 2, thus can also allow two mouldings 4 set according to 3 longitudinal direction of curtain it Between have enough distances so that the curtain 3 can completely be unfolded, relatively good drop shadow effect is obtained, along with the curtain Cloth 3 is slidably connected with two longitudinally disposed mouldings 4, i.e., the curtain 3 can be vertically moved along moulding 4, so that the curtain Cloth 3 can coordinate projecting apparatus to carry out height adjusting, and then obtain better drop shadow effect.

As preferred embodiment, the both ends of moulding 4 are respectively arranged with hole button 401, the hole button of the wherein one end of moulding 4 401 other end formation for being articulated in support bar 2 are detachably connected, and the hole button 401 of 4 other end of moulding is articulated in another support bar 2 The other end formation be detachably connected, this structure being detachably connected is simple, easy to operation, and can so that this is portable Projector curtain frame is convenient for carrying.Specifically, 2 other end of support bar is provided with gum cover (not shown), is provided on gum cover recessed Circle, hole button 401 are articulated in be formed on recessed circle and be detachably connected, and structure letter can both have been realized by being articulated on recessed circle by hole button 401 The single, stabilization easy to operation for being detachably connected, and the stability of connection can be increased, i.e., being connected between moulding 4 and support bar 2 Property, even in the case where external environment is unstable, such as wind, collision etc., moulding 4 and support bar 2 will not take off easily It falls.

By being respectively arranged with the sleeve isometric with 3 longitudinal side of the curtain at two longitudinal sides of the curtain 3 301, two longitudinally disposed mouldings 4 are slidably connected across sleeve 301 with the curtain 3, and sleeve 301 is equivalent to the work of a guiding With, the slip of the curtain 3 can be facilitated, and ensure that the curtain 3 slide when do not deviate by view field.Specifically Ground, two longitudinal sides of the curtain 3 are respectively facing the 3 inside fold of curtain and form sleeve 301, in this way convenient for sleeve 301 Quick Fabrication, and make simple, no complicated technology.

By being provided with flexible support item 6 on the non-perspective plane of the curtain 3, the both ends of flexible support item 6 respectively with the curtain The both ends connection of the transverse sides of cloth 3, the middle part of flexible support item 6 are connect with the middle part of another transverse sides of curtain 3, this Sample flexible support item 6 can support expansion curtain on the vertical and horizontal direction of the curtain 3, and the curtain 3 is had Certain wind resistance.Specifically, flexible support item 6 is two, and two flexible support items 6 are symmetrical arranged, and are symmetrically set in this way The wind resistance of the curtain 3 can further be improved by putting.More specifically, four angles of the curtain 3 are respectively arranged with fixed part 5, The both ends of flexible support item 6 are inserted into the formation of fixed part 5 and are detachably connected, and setting in this way can cause the portable projector curtain Frame is more easy to assemble so as to more portable.More specifically, fixed part 5 is housed by four angles of the curtain 3 with the interlayer that cloth is formed Space is formed, and the both ends of flexible support item 6 are inserted into four angles of the curtain 3 and the interlayer accommodating space of cloth formation, cloth The fixed part 5 formed with the curtain 3 makes simply.More specifically, cloth is elastic woven material, elastic woven material can give flexible support The space of 6 one bufferings of item, the curtain 3 is damaged in the end for being effectively reduced flexible support item 6.

The above embodiment is only the preferred embodiment of the utility model, it is impossible to be protected with this to limit the utility model Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacing belongs to In the utility model range claimed.
