Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be described in detail the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of protection of the invention.
Shown in ginseng Fig. 1, large scale scrolling curtain system is greater than the projection screen of 5 meters mainly for width, but it should be noted that it equally also goes for undersized projection screen.
Large scale scrolling curtain system comprises mounting bracket 10, the core pipe 20 be fixed on mounting bracket 10, below core pipe 20 and the scrolling pipe 30 parallel with core pipe 20, the motor 50 that is connected to the projection screen 40 between core pipe 20 and scrolling pipe 30 and is fixed on mounting bracket 10.
Shown in composition graphs 2 and Fig. 3, mounting bracket 10 comprises body of wall erecting frame 11 and can hang on the suspension holdfast 12 on body of wall erecting frame 11.
The semi-girder 112 that body of wall erecting frame 11 is comprised pad 111 and fixed by welding manner and pad 111, pad 111 is fixed on body of wall by screw.Because pad 111 has certain thickness, between semi-girder 112 and metope, certain gap can be formed.
Suspension holdfast 12 being fixed with some hooks 121, by linking up with the effect of 121, can suspension holdfast 12 entirety being hung on semi-girder 112, simultaneously for convenience detach.
Shown in composition graphs 4, suspension holdfast 12 comprises main support 122 and is positioned at left socle 123 and the right support 124 of main support 122 both sides, and grafting is provided with the connecting link 125 of level between main support 122 and left socle 123 and between main support 122 and right support 124.Connecting link 125 is by inserting mode, and easy assembly and disassembly, during assembling, need after grafting completes to be fixed further by screw, to increase strong degree.
The two ends of core pipe 20 are individually fixed on left socle 123 and right support 124, and core pipe 20 is in order to the top of fixing projection screen 40.Because the projection screen 40 that is connected with scrolling pipe 30 can form a larger downward pulling force to core pipe 20, core pipe 20 length is comparatively large simultaneously, under the pulling force of projection screen 40, is easy to bend, and therefore can form impact to the flatness of projection screen.In order to avoid bending of core pipe 20, between the top of core pipe 20 and suspension holdfast 12, be preferably provided with 3 support bars 60.The bottom of support bar 60 is provided with external thread, and the top of core pipe 20 coordinates this external thread to be provided with fixed orifice, and can to realize with fixed orifice fixing by rotating for the bottom of support bar 60.The top of support bar 60 is fixed on suspension holdfast 12 preferably by nut.
Scrolling pipe 30 is installed on the bottom of projection screen 40, and it can carry out rolling along the first clockwise to projection screen 40.The two ends of scrolling pipe 30 are respectively equipped with a wirerope-winding end 31.
Shown in composition graphs 5, motor 50 is installed on main support 122, and its output terminal is connected to a two-way serving sleeve 70 by spiral gear 51, and two-way serving sleeve 70 can be driven to rotate.Two-way serving sleeve 70 has two synchronous reels 71, two reels 71 are wound with wire rope 80 along different clockwise respectively, two wire rope 80 are drawn from the both sides of two-way serving sleeve 70, two wire rope 80 are guided respectively by a pulley 90, and are wound in respectively on the wirerope-winding end 31 at scrolling pipe 30 two ends.Two pulleys 90 are installed on left socle 123 and right support 124 respectively.Wire rope is wound on wirerope-winding end 31 along the second clockwise, and the first hour hands are contrary with the second clockwise.Carry out in wrapup procedure at projection screen 40, wirerope-winding end 31 pairs of wire rope 80 at scrolling pipe 30 two ends discharge, and meanwhile, scrolling pipe 30 main part carries out rolling to projection screen 40.
In wrapup procedure, the wire rope at two ends plays certain supporting role to scrolling pipe 30, has shared scrolling pipe and has pullled effect to screen, projection screen therefore can be avoided to be pulled off.
Motor 50 can be connected with controller by wired or wireless mode, is controlled rotation direction and the velocity of rotation of motor 50 by controller.
