Description
Technical field
The utility model relates to a kind of projector display module, particularly relates to the height-adjustable projection screen of a kind of suspension.
Background technology
At present, the back projection type projection screen adopts the form of screen sticking glass mostly, because the density of glass is very big, in case therefore screen size is excessive, as greater than 80 inches, screen will be overweight.And along with the prolongation of hanging the time, barbola work will slowly lose efficacy under stress, and screen just has the danger that comes off at any time.In order to alleviate the weight of back projection type projection screen, plastic cement structure screen has appearred, to replace the screen of plastic cement sticking glass on the market.Though plastic cement structure screen can well alleviate the weight of back projection type projection screen, plastic cement structure screen also has its shortcoming.Because screen is the plastic cement structure fully, the plastic cement screen expands because of temperature, the humidity variation of environment easily or shrinks, if the plastic cement screen is completely fixed on the rear-projection case, and the rear-projection case can not be out of shape owing to its rigid structure, therefore the plastic cement screen can not freely stretch, be subjected to gravity and environmental impact when distortion, the plastic cement screen can produce irregular external drum, has brought problems such as, distortion not fogging such as screen center.Therefore, in order to solve the problem of plastic cement screen bulging, present plastic cement screen is general to be adopted and the unsteady ways of connecting of rear-projection case, to guarantee screen enough expansion spaces is arranged.But this fixed form can not be born too big weight owing to be connected with the rigid of rear-projection case, facts have proved, the multihead display system that uses this structure generally can not limit applying of plastic cement screen greatly above two-layer.
The utility model content
The purpose of this utility model is to provide that a kind of distortion is little, cost is low, the height-adjustable projection screen of suspension in light weight, that scalability is good.
The purpose of this utility model is achieved through the following technical solutions: the height-adjustable projection screen of a kind of suspension, comprise screen and rear-projection case, also comprise and hang section bar, adjusting part and suspension assembly, described screen top is fixed on and hangs on the section bar, hang section bar and be connected with suspension assembly by adjusting part, suspension assembly is fixed on the rear-projection case.
For better realizing the utility model, described suspension assembly is two, is separately fixed at the two ends of rear-projection box top, hangs the section bar two ends and all is connected with suspension assembly respectively by adjusting part.
Described screen top is fixed on and hangs on the section bar, specifically is meant, described screen top is fixed on by helicitic texture and hangs on the section bar.
Described screen top is fixed on and hangs on the section bar, can also be that the screen top is hanging on the section bar by the screen glue.
Described suspension assembly is fixed on the rear-projection case, specifically is meant, described suspension assembly is fixed on the rear-projection case by helicitic texture.
Described suspension assembly is fixed on the rear-projection case, can also be that suspension assembly is fixed on the rear-projection case by welding manner.
Described each adjusting part comprises nut and is mated the double-screw bolt of use, and described double-screw bolt is fixed on and hangs on the section bar, and nut is installed on the suspension assembly and can rotates freely.In the double-screw bolt precession nut,, can adjust up and down hanging section bar by the turn nut, thus the height of adjustment screen.
Described double-screw bolt is fixed on and hangs on the section bar, is meant that specifically double-screw bolt is by pressing or welding manner is fixed on and hangs on the section bar.
Described suspension assembly adopts aluminium alloy processing or sheet metal component to be welded.
The manufactured materials of described suspension section bar is aluminium section bar or sheet metal component.
The utility model compared with prior art has following advantage and beneficial effect:
The first, the utility model projection screen top adopts the suspension section bar to fix, the gravitional force that can utilize screen itself vertically downward, to satisfy the plastic cement screen because of the temperature of environment, the demand that the humidity variation is expanded or shunk, avoid the generation of external drum phenomenon, thereby make the shown clear picture of projection screen, distortion little, brought good viewing effect.
The second, scalability is good, can satisfy actual needs; If dull and stereotyped plastic material is subjected to being easy to fracture perpendicular to the power of planar surface, but the power that plastic cement screen of the present utility model is subjected to is the longitudinal force that gravity forms, and is parallel to the surface of screen, therefore can bear bigger stress; Be compared to the plastic cement structure screen and the unsteady ways of connecting of rear-projection case of present employing, plastic cement screen of the present utility model can be hung 5 layers of 80 inches screen at least, better meets the needs in market.
