Description
Technical field
The utility model relates to the motor-driven projection screen of a kind of light-operated tubulose.
Background technology
Projector and projection screen are used in conjunction with and represent picture, need the position of lateral adjustments projection screen under some states, as projector light illumination range cannot be adjusted to ad-hoc location etc.
Summary of the invention
The object that the utility model will reach is to provide the motor-driven projection screen of a kind of light-operated tubulose, can automatically regulate according to illumination the position of projection screen body.
In order to achieve the above object, the utility model adopts following technical scheme: the motor-driven projection screen of a kind of light-operated tubulose, comprise tube shaped electric machine and projection screen body, tube shaped electric machine is provided with regulating device, regulating device comprise tooth bar and with the fixing casing of tube shaped electric machine, tooth bar and casing are separable, in casing, be provided with worm screw and gear, worm shaft is to parallel with tooth bar length direction, gear and worm mesh, gear is exposed to outside casing and engages with tooth bar, gear and cabinet wall are rotationally connected by rotating shaft, worm screw and cabinet wall are rotationally connected, worm screw is driven by motor, projection screen body lower edge two ends are left photoelectric sensor and right photoelectric sensor respectively, and left photoelectric sensor, right photoelectric sensor can produce the signal that makes electric motor starting drive worm screw.
Tooth bar is fixed on body of wall or other fixtures, tube shaped electric machine is slidably connected by the things such as slide rail and exterior object, under normal condition, after projector starts, in the folding process of projection screen body, left photoelectric sensor and right photoelectric sensor are all subject to the strong illumination of projector, when projector light is according to deflection, when the left side of projection screen body or right side are no longer subject to projector light photograph, the photoelectric sensor of this side is no longer subject to illumination, now this photoelectric sensor sends and makes electric motor starting and by the signal of a direction rotation turning to, motor rotates worm screw, worm screw is rotated rear driven gear and rotates, because gear engages with fixing tooth bar, the direction that drives casing after gear rotates and rotate according to gear with the fixing tube shaped electric machine of casing is traversing to a side, until be not subject to the photoelectric sensor of illumination to be again subject to illumination.
Adopt after technique scheme, the utlity model has following advantage:
Be subject to the automatic starter motor of difference of light to regulate the position of projection screen body according to left photoelectric sensor, right photoelectric sensor.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the schematic diagram of a kind of embodiment of the utility model;
Fig. 2 is the schematic diagram that in Fig. 1 embodiment, casing is analysed and observe
Embodiment
Fig. 1,2 is depicted as a kind of embodiment of the present utility model.
The projection screen that a kind of light-operated tube shaped electric machine 1 drives, comprise tube shaped electric machine 1 and projection screen body 2, tube shaped electric machine 1 is provided with regulating device, regulating device comprise tooth bar 3 and with the fixing casing 4 of tube shaped electric machine 1, tooth bar 3 is separable with casing 4, in casing 4, be provided with worm screw 5 and gear 6, worm screw 5 is axially parallel with tooth bar 3 length directions, gear 6 engages with worm screw 5, gear 6 is exposed to outside casing 4 and engages with tooth bar 3, gear 6 is rotationally connected by rotating shaft 7 with casing 4 inwalls, and worm screw 5 is rotationally connected with casing 4 inwalls, and worm screw 5 is driven by motor (not shown); Projection screen body 2 lower edge two ends left photoelectric sensor 8 and right photoelectric sensor 9 respectively, left photoelectric sensor 8, right photoelectric sensor 9 can produce the signal that makes electric motor starting drive worm screw 5.
Tooth bar 3 is fixed on body of wall or other fixtures, tube shaped electric machine 1 is slidably connected by the things such as slide rail and exterior object, under normal condition, after projector starts, in 2 folding processes of projection screen body, left photoelectric sensor 8 and right photoelectric sensor 9 are all subject to the strong illumination of projector, when projector light is according to deflection, when the left side of projection screen body 2 or right side are no longer subject to projector light photograph, the photoelectric sensor of this side is no longer subject to illumination, now this photoelectric sensor sends and makes electric motor starting and by the signal of a direction rotation turning to, motor rotates worm screw 5, worm screw 5 is rotated rear driven gear 6 and rotates, because gear 6 engages with fixing tooth bar 3, the direction that drives casings 4 after gear 6 rotates and rotate according to gear 6 with the fixing tube shaped electric machine 1 of casing 4 is traversing to a side, until be not subject to the photoelectric sensor of illumination to be again subject to illumination.
Except above preferred embodiment, the utility model also has other embodiment, those skilled in the art can make various changes and distortion according to the utility model, only otherwise depart from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
