Embodiment
With reference to the accompanying drawings and examples, the utility model is expanded on further.
As Fig. 1 and Fig. 2 are jointly shown, the folding and unfolding of curtain 4 is realized in the rotating of rotating shaft, lifting assembly 6 control fixed mount with The distance between fixed plate 5 realizes the expansion and gathering of curtain 4.One end of curtain 4 is fixed on the axial plane of rotating shaft 2, curtain 4 Main part is wrapped in rotating shaft 2 layer by layer, and the exposed one end of curtain 4 is fixed in fixed plate 5, pulls the exposed one end of curtain 4 It can realize that curtain departs from from rotating shaft, 4 exposed one end of curtain is fixed in fixed plate 5, with the adjustment fixing plate of lifting assembly 6 5 relative to the distance between fixed mount 1, and curtain 4 can also deploy so as to reach the height that projector equipment project needs accordingly Degree.When in use, fixed mount 1 is fixed placement, and the spacing between original state bottom plate 5 and fixed mount 1 is minimum, passes through liter For the adjustment effect of part 6 of coming down to a lower group so that fixed plate 5 is moved to precalculated position away from fixed mount 1, realization pulls the exhibition of curtain 4, i.e. curtain 4 Open, be now the use state of device, when returning to original state from use state, lifting assembly 6 controls fixed plate 5 towards admittedly Determine frame 1 to move, while control rotating shaft 2 to rotate spooling curtain 4, realize the gathering of curtain 4.
As shown in Fig. 2 the scissor-type lifting mechanism 14 of single-stage, which is two connecting rods 15, is hinged composition in the centre position of bar, it is whole Body is in X-shaped, and scissor-type lifting mechanism 14 shares four ends of connecting rod 15, the end of two connecting rods 15 be arranged in chute 13 and Slided with the action of scissor-type lifting mechanism 14 in chute 13, curtain 4 is connected in fixed plate 5, because curtain 4 possesses Certain elasticity so that the curtain 4 of tensioning can produce a pulling force so that what connecting rod 15 slided in chute to fixed plate 5 It will not go out depart from from the notch of chute 13 simultaneously, the other end of two connecting rods 15 is hinged on two contiguous blocks 12, with fixed plate 5 Spacing between fixed mount 1 is the height of scissor-type lifting mechanism 14, and the spacing between two liters of curtain motors 10 is scissor-type The width of elevating mechanism 14, when two liters of curtain motors 10 slide relatively, drive two contiguous blocks 12 close, so that installed in connection The both ends of scissor-type lifting mechanism 14 on block 12 are relatively close, and the global shape width of scissor-type lifting mechanism 14 is reduced, Length increase;When two liters of curtain motors 10 under being driven by liter curtain motor 10 are relatively distant from, the overall shape of scissor-type lifting mechanism 14 Shape width increases, and length is reduced, by realizing adjustment of the lifting assembly 6 to spacing between fixed plate 5 and fixed mount 1 with upper type And the two is relatively fixed, scissor-type lifting mechanism 14 can form support to the main body of curtain 4.
As shown in figure 5, two-stage lifting assembly 6 can increase the adjustable range between fixed plate 5 and fixed mount 1.
As shown in figure 5, line slideway 8 ensure that the smoothness that liter curtain motor 10 slides along rack 7.
As Fig. 5 and Fig. 6 are jointly shown, curtain expansion or when collapsing, rise curtain motor have on fixed mount two it is corresponding Position, two limit switches are separately mounted at above-mentioned two positions so that rise curtain motor at above-mentioned position can and limit switch Generation sensing contact, the electric machine spacing control detection module built in limit switch can issue induction information at microprocessor, micro- place The driving of reason device controlled motor passes through two liters of curtain motors so as to the closing for controlling liter curtain motor with receiving curtain motor, the process of curtain expansion Move towards to realize, when curtain is fully deployed, the limit switch in centre position contacts with rising the generation sensing of curtain motor, so The power-off of curtain motor is risen afterwards;When curtain need collapse when, two liters of curtain electric motor startings and towards be located remotely from each other direction movement, receive simultaneously Curtain electric motor starting, drive shaft rotate and realize the circumvolution of curtain, until liter curtain motor and the limit switch of avris position sense Contact, rise curtain motor and stop with receiving curtain motor.
As shown in figure 5, it is steering wheel to rise curtain motor 10.Steering wheel transmission is accurate, the auto-lock function being also equipped with after simultaneously closing off, i.e., The motor shaft of steering wheel can be locked without being rotated by external force after steering wheel power-off, so go for device and put vertically Used when putting.The auto-lock function of steering wheel can cause scissor-type lifting mechanism 14 to keep stationary state, form supporting role.
As shown in figure 4, receiving curtain motor 3 realizes the motorized motions of rotating shaft 2.
As shown in figure 4, swing handle 8 facilitates human hand to move rotating shaft 2.
As Fig. 1 and Fig. 2 are jointly shown, in original state, the part in device in addition to fixed mount 1 is all disposed within sky Heart column body so that device generally in closing state, so as to ensure that the critical piece of device when not in use will not be by The impurity such as extraneous dust pollute, and perforate 16 can realize freely coming in and going out for fixed plate 5.
A kind of sound equipment, including loudspeaker casing, above-mentioned projection curtain device is installed on voice box casing, due to noted earlier Projection curtain device occupation mode it is various, the sound equipment installed and be used cooperatively therewith can in several ways with projection screen Device is applied in combination.So as to realize that the drop shadow effect of sound equipment possesses diversity, meet different use demands.
The utility model is not limited to above-mentioned specific embodiment, and one of ordinary skill in the art visualizes from above-mentioned Hair, without performing creative labour, a variety of conversion made, all falls within the scope of protection of the utility model.
