Description
Technical field
The utility model relates to a kind of projection arrangement, particularly relates to a kind of Backpack type projection arrangement.
Background technology
Projection arrangement is a kind of equipment that image or video information can be projected on curtain, can by different interfaces same computing machine, VCD, DVD, BD, game machine, DV etc. be connected play corresponding vision signal.Most conventional projection device comprises projector, curtain and desk.During use, projector is placed on desk, the right opposite of projector is a curtain, the image of projector or video information project on curtain and show, distance far away shown by image or video larger, the shortcoming of conventional projection device is that projector equipment volume is excessive, is inconvenient to carry.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of folding Backpack type projection arrangement, after knapsack is supported, the utility model can as a projection arrangement, very convenient to carry, after knapsack is compressed, significantly reduce the volume of Backpack type projection arrangement further, carry convenient.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of Backpack type projection arrangement, comprise knapsack, it is characterized in that in described knapsack, being provided with projector and at least one catoptron, antetheca has projection screen with described knapsack, the horizontal expansion direction of catoptron is consistent with the horizontal expansion direction of projection screen, many support bars are inserted with in described knapsack, the bearing of trend of described support bar is consistent with the horizontal expansion direction of catoptron, knapsack struts by many described support bars, the both sides of catoptron are connected to the sidewall of knapsack by telescopic component, the light that projector sends is incident upon on projection screen after catoptron reflection, by support bar from after knapsack detaches, knapsack is compressed to sidewall direction, catoptron turn to 90 degree parallel with sidewall.
Further preferred version is: described telescopic component comprises gathering components, and one end of described gathering components is connected with catoptron one end, and the other end of described gathering components is connected with sidewall.Gathering components can make catoptron be connected with gathering components and freely overturn, and can be superimposed when folded projection device parallel with knapsack sidewall for catoptron.
Further preferred version is: described gathering components is the structure that pleated sheet is connected successively.The function that just can realize freely overturning of pleated sheet connected structure successively.
Further preferred version is: described catoptron is two, be respectively the first catoptron and the second catoptron, described projector is arranged on the inside sidewalls of knapsack, described projector is positioned at the top of projection screen, the first described catoptron is positioned at the rear side of projector, and the second described catoptron is positioned at the below of the first catoptron.The light that projector sends reflexes to the second catoptron through the first catoptron, and the light of the second catoptron reflection projects on projection screen again.
Further preferred version is: the front end of the first described catoptron is connected with the roof of knapsack by the first connecting band, the rear end of the first catoptron is connected with the rear wall of knapsack by the second connecting band, the front end of the second catoptron is connected with the diapire of knapsack by the 3rd connecting band, and the rear end of the second catoptron is connected with the rear wall of knapsack by the 4th connecting band.The first catoptron and the second catoptron can be made not easily to rock by arranging the first connecting band, the second connecting band, the 3rd connecting band and the 4th connecting band, strengthening fixed effect.
Further preferred version is: the junction surface of connecting portion between gathering components and catoptron of the first described connecting band or the second connecting band or the 3rd connecting band or the 4th connecting band and catoptron.Be arranged on the characteristic that can overcome connecting band is arranged on because of gathering components softness on gathering components on the junction surface between gathering components and catoptron and bring the shortcoming of not easily fixing catoptron, also can overcome and connecting band be arranged on the mirror because the poor shortcoming of the fixed effect too closely caused that leans on of point of fixity, better fixed effect can be brought.
Further preferred version is: be provided with the cloth cover with elongated hole in described knapsack, in the cloth cover described in described support bar inserts.Support bar inserts in cloth cover can strut whole knapsack.
Further preferred version is: described support bar has four, and described support bar is distributed in four corners of knapsack.Arrange four and strut position, can bring and better strut effect.
Further preferred version is: described knapsack antetheca top is inserted with puts post, and projector is shelved on the top of post, and a support bar of antetheca inside front is positioned at the top of projector, described puts post and this support bar forms a projector fixed frame jointly.
Compared with prior art, projector light of the present utility model, by lighttight light path reflection unit, makes light through once or multiple reflections, finally projects to the process of projection screen imaging.By light path reflection unit, traditional approach linear light path is become multiple folded light path, the requirement that projector is adjusted the distance greatly reduces, and reduces projection arrangement to the requirement in space., by projector, catoptron and projection screen are integrated in a knapsack that can be convenient for carrying, take up room little meanwhile, easy to carry.When using projector equipment, support bar being inserted in knapsack, props up whole projector equipment, light projects on projection screen by inner reflection; When not using projector equipment, extract out support bar, knapsack is compressed toward sidewall direction, counter for catoptron turn 90 degrees parallel with sidewall, formed one flattening knapsack, take up room less, carry more convenient.
