Abstract
The utility model relates to a high-gain wrinkle-free projection screen that is formed by stretching a screen with braided base cloth and optical gain adhesive film layer on a torsion spring frame, wherein the torsion spring frame has certain tension, the braided base cloth is woven with elastic yarn with radio between 50-85 percent and common yarn with ratio between 15-95 percent, the woven codeweight is between 80-400g, and while the optical gain adhesive film layer is formed by mixing optical gain powder into adhesive. As the screen has proper elasticity, the proper tension offered by thetorsion spring frame is used to spread the screen when the high-gain wrinkle-free projection screen is spread for use, thus causing the screen to recover neat and wrinkle-free status quickly and effectively avoiding the influence on the quality of projected images.
Description
Technical field
The utility model relates to a kind of projection screen, particularly relates to a kind of use that is easy to carry, folding be difficult for crimped high-gain and do not have the wrinkle projection screen.
Background technology
Along with the appearance of projector, no matter be teaching or bulletin work, also thereby can carry out more quickly and easily.In addition, because the progress of science and technology a kind ofly can connect PC or notebook computer, be stored in digital image data in the computer with reception, and then the color projector that the image projection is presented on the projection screen arises at the historic moment.
Existing known projection screen normally is fixed on the wall, is beneficial to the image that projector's projection desire shows.But, as teaching or bulletin place not installing projection screen or desire to impart knowledge to students out of doors or during bulletin work, then the preparation of projection screen just can become a puzzlement greatly, in fact remains further to be improved, and is beneficial to impart knowledge to students or the carrying out whenever and wherever possible of bulletin work.
In view of the above, No. 97221502 case of TaiWan, China patented claim proposes a kind of folding not taking up space when taking in and is easy to carry and is easy to the Portable projection screen launching to use.Only be convenient to folding demand of carrying because of projection screen, make projection screen through repeatedly folding, launch after, often also can on projection screen, stay gauffer lines more or less, so that influence the quality of projection image significantly.

Embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, to do not have its embodiment of wrinkle projection screen, structure, feature and effect thereof according to the high-gain that the utility model proposes, describe in detail as after.
Fig. 1 to Fig. 3 shows not have the wrinkle projection screen according to a kind of high-gain of the utility model preferred embodiment, show among the figure, this high-gain does not have wrinkle projection screen 10 and comprises: torque spring frame 11 reaches opens the curtain 12 that is distributed on the torque spring frame 11, and curtain 12 has more braiding base fabric 121 and gain of light adhesive film 122.
Wherein, has suitable flexible braiding base fabric 121 in order to provide, select for use as polyethylene terephthalate (PolyEthylene Terephthalate, be called for short PET), polybutylene terephthalate (PolyButylene Terephthalate, be called for short PBT), PTT (PolyTrimethylene Terephthalate, be called for short PTT), nylon 6 (Nylon 6), nylon 66 (Nylon 66), nylon 632 (Nylon 632), cotton, the acryl fiber, polypropylene (PolyPropylene, be called for short PP), rayon (rayon), the general yarn of flax fiber (flax) or wool and so on, and as Lycra (lycra), the elastomeric yarn of ameripol fiber (elastomeric) or elastic artificial fiber (spandex) and so on is woven and is formed.
During braiding, the ratio of the elastomeric yarn of use is preferably between 5%-85%, and the ratio of general yarn is then between 15%-95%.The method of braiding for example can be used plain weave, knitting, tatting or knit through the limit, and the tissue of braiding can be planar cloth, screen cloth or bird's eye cloth, and the code weight of finishing braiding is preferably then between 80g-400g.
In addition, on the braiding base fabric 121, more with suture way or with as poly-mephenesin Carbamate (PolyUrethane, abbreviation PU glue), Polyvinylchloride (PolyVinylidene Chloride, abbreviation PVC glue), polyvinylacetate (PolyVinyl Acetate, be called for short PVA glue), acryl resin or vinyl acetate resin (Vinyl Acetate), the gain of light adhesive film 122 of fitting.Sewing up or the purpose of applying gain of light adhesive film 122, is in order the high gain characteristics of curtain 12 to be provided, to make the image that is projected on the curtain 12 can be more clear and bright.
The formation method of gain of light adhesive film 122 is to be mixed in the PU glue by the gain of light powder as aluminium, silver, iron, copper, zinc, titanium, nickel, mica, pearl essence, silicon dioxide powder, glass dust or flatting silica etc. to form.The thickness that forms is preferably between 0.1 millimeter-1.5 millimeters, and the ratio that gain of light powder uses is preferably between 0.1%-40%, and particle diameter is preferably then less than 35 microns.
Do not have wrinkle projection screen 10 and be convenient to folding carrying in order to reach this high-gain, and fold and be difficult for crimped characteristic, the aforementioned stitching or the formed curtain 12 of fitting, and again to sew up or mode that other are fixing and opening is distributed on the torque spring frame 11, and employed torque spring frame 11 is preferably the tension force with 0.3Kg-5.5Kg, so that when high-gain not being had the 10 expansion uses of wrinkle projection screen, can open curtain 12 by the suitable tension force that torque spring frame 11 is provided, make curtain 12 be able to elasticity by the tension force of torque spring frame 11 and curtain 12 itself, and can promptly recover smooth non-wrinkled state, avoid influencing the quality of projection image.Certainly, as have the knack of known to this skill person, the size of the tension force of torque spring frame 11 is to adjust according to ratio, code weight and the area of the yarn of curtain 12.
In addition, high-gain does not have torque spring frame 11 that wrinkle projection screen 10 uses and has more torsion between between 0.2Kg-1.5Kg, does not have the folding preferable effect of taking in wrinkle projection screen distortion back so that high-gain to be provided.When taking in, be the torque spring frame 11 that high-gain is not had wrinkle projection screen 10, impose torsion and twist into behind 8 fonts foldingly again that then shared area will have only half of former torque spring frame 11.When desire contracts area more hour, the ground twisting in regular turn once more of also can following the prescribed rules, make more littler 8 continuous fonts after, give foldingly again, so can reach easily and take in the convenience that carries, and can promptly recover smooth effect when launching to use.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art are not in breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
