Fig. 2 is screen fixture structural representation in the utility model projection screen embodiment;
Fig. 3 is the assembling schematic diagram of wall hanging frame and fixed mount in the utility model projection screen embodiment.
Embodiment
For making object, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1-Figure 3, the present embodiment projection screen, comprises projection screen 10 and for the screen fixture of projection screen 10 is installed, screen fixture comprises back up pad 1 and double faced adhesive tape 2, double faced adhesive tape 2 sticks on the surface of back up pad 1, and projection screen 10 is bonded in back up pad 1 by double faced adhesive tape 2.
Particularly, the projection screen 10 that 1 pair of back up pad of the present embodiment projection screen employing will be fixing supports fixing, and projection screen 10 is bonded in back up pad 1 by double faced adhesive tape 2.Double faced adhesive tape 2 can firmly be bonded in each position of projection screen 10 in back up pad 1, avoids occurring that the phenomenon of perk occurs projection screen 10.And back up pad 1 can effectively support whole projection screen 10, avoid occurring projection screen 10 because of gravity or be subject to wind that fold occurs, to guarantee that projection screen 10 remains higher surface smoothness, to obtain higher display effect.Wherein, can in back up pad 1, paste the double faced adhesive tape 2 of specific quantity according to the concrete size of projection screen 10, to guarantee whole good being bonded in back up pad 1 of projection screen 10.
Preferably, the back up pad 1 in the present embodiment is honeycomb plate structure, and honeycomb plate structure comprises two panels (not shown) and is clipped in two honeycomb cores (not shown) between panel.Concrete, the back up pad 1 of honeycomb plate structure can effectively strengthen the overall construction intensity of back up pad 1 on the one hand, can effectively reduce on the other hand the weight of back up pad 1, realizes light-weight design.Wherein, in the present embodiment, the thickness of the panel of honeycomb plate structure is 0.8 mm-1.5mm, and panel is alloy aluminium sheet.Concrete, adopt alloy aluminium sheet can effectively strengthen the structural strength on back up pad 1 surface as panel, so that 1 pair of projection screen 10 of back up pad supports, meanwhile, also facilitate in back up pad 1 miscellaneous part is installed; And the alloy aluminium sheet of employing suitable thickness can be realized and meeting under the prerequisite of back up pad 1 surface structure intensity, effectively alleviate integral thickness and the weight of back up pad 1.In addition, in the present embodiment, the thickness of the honeycomb core of honeycomb plate structure is 10 mm-25mm.Concrete, due to the main support parts of honeycomb core as back up pad 1, the size of back up pad 1 can be set according to the size of projection screen 10, meanwhile, in back up pad 1, need according to the increase and decrease of size and the thickness of corresponding increase and decrease honeycomb core, to meet the demand of overall construction intensity.And honeycomb hole lattice in honeycomb core are sexangle, hexagonal honeycomb hole lattice can strengthen the resistance to overturning of honeycomb core on the one hand, can effectively reduce on the other hand the use amount of material, to alleviate whole weight.The length of side 4mm-8mm of the honeycomb hole lattice in the present embodiment, by selecting the honeycomb hole lattice of the suitable length of side, can obtain the honeycomb plate structure of different densities, can meet the requirement to structural strength under back up pad 1 different size condition.
Further, the present embodiment projection screen also comprises installing frame 3, and installing frame 3 is fixed in back up pad 1 and wraps the edge of back up pad 1.Concrete, installing frame 3 can be fixed by screws in the edge of back up pad 1, by installing frame 3, the edge of back up pad 1 is wrapped, and to avoid the edge of back up pad 1 outside exposed, optimizes the appearance effect of the present embodiment projection screen.
Further, the present embodiment projection screen also comprises wall hanging frame 4 and fixed mount 5, and wall hanging frame 4 is fixed in back up pad 1; When the present embodiment projection screen is mounted on wall, fixed mount 5 is fixed on wall, and wall hanging frame 4 hangs on fixed mount 5.Concrete, the present embodiment projection screen self is fixed with wall hanging frame 4, and fixed mount 5 is for being fixed on wall, by wall hanging frame 4 and fixed mount 5, coordinates, and can realize the present embodiment projection screen is mounted on wall easily.Wherein, the wall hanging frame in the present embodiment 4 has the first bending plate 41 of bending down; Fixed mount 5 has the second bending plate 52 of bending upward, and when the present embodiment projection screen is mounted on wall, the first bending plate 41 hangs on the second bending plate 52.
The projection screen that the utility model provides, by be provided with double faced adhesive tape in back up pad, projection screen is by the bonding back up pad of double faced adhesive tape, double faced adhesive tape can firmly be bonded in back up pad by each position of projection screen, and back up pad can effectively support projection screen, after projection screen mounts on the wall by screen fixture, the whole supported plate of projection screen supports, the surrounding of projection screen and interior zone can obtain effective support and location, the surface of guaranteeing projection screen has higher flatness, thereby improves display effect.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
