Embodiment
The technical matters solved to make the utility model, the technical scheme of employing, the technique effect easy to understand obtained, below in conjunction with concrete accompanying drawing, be described further embodiment of the present utility model.
Referring to figs. 1 to Fig. 3, the utility model provides a kind of secondary lifting electric projection screen, and it comprises housing 3, the lower ending opening of this housing 3, and overall in tubular.The two ends of described housing 3 are provided with left socle 9, right support, and wherein, it is inner that left and right support is positioned at housing 3, and be fixed on the two ends of housing 3.Also be provided with in described housing 3 by moving pipe 6 in the curtain of the first motor 7, in the driving curtain making the first motor 7 passable, pipe 6 rotates in housing 3.In the embodiment that the utility model one is concrete, first motor 7 can be fixed on left socle 9, in curtain, one end of pipe 6 is rotatably connected on right support by means well-known to those skilled in the art, such as installed etc. by bearing, in curtain, the other end of pipe 6 and the output terminal of the first motor 7 link together, thus achieve the installation of pipe 6 in curtain, and, pipe 6 in curtain can be driven to rotate on right support by the first motor 7.
In described curtain, pipe 6 has been intertwined and connected curtain 8, and the one ends wound of described curtain 8 is connected in curtain on pipe 6, and Open Side Down stretches out from housing 3 for its other end.That is, the first motor 7 drives pipe 6 in curtain to rotate, thus can realize the folding and unfolding of curtain 8.
Screen of dynamoelectric projection of the present utility model, at institute's left socle 9, right support is also provided with the rotating shaft 5 being controlled by the second motor, in the mounting means of rotating shaft 5 and curtain, the mounting means of pipe 6 is substantially similar, in order to balance described projection screen, described second motor can be fixed on right support, one end of rotating shaft 5 is rotatably connected on left socle 9 by mode well-known to those skilled in the art, such as installed by modes such as bearings, the other end of described rotating shaft 5 and the output terminal of the second motor link together, thus achieve the installation of rotating shaft 5 in housing 3, and can drive shaft 5 be rotated on left socle 9 by the second motor.Also comprise winding band 2, the lower end of described winding band 2 is passed described housing 3 and is wrapped in rotating shaft 5, and its upper end is used for fixing with external environment condition.With reference to figure 1, the upper end of winding band 2 is fixed on ceiling 1, and certainly, for a person skilled in the art, according to the difference of projection screen installation environment, winding band 2 can be fixed on other position.And, such as can on ceiling 1 mounting bracket, described winding band 2 can by hook directly hang on mounting bracket, to realize the Fast Installation of projection screen.Second motor-driven rotatable shaft 5 is rotated, thus can realize the action of the folding and unfolding of winding band 2, finally achieves rising or the down maneuver of housing 3.Preferably, described winding band 2 is steel band.
