Description
Technical field
This utility model belongs to a kind of projection screen, particularly to the electric curtain of a kind of Double-lifting.
Background technology
Projection screen is installed, it is common that be arranged on wall or under furred ceiling；But for the place that floor is higher, if being directly arranged on furred ceiling by projection screen, owing to position is the highest, spectators need to raise the head to see projection.Therefore to reduce the setting height(from bottom) of projection screen, people first install motor and spool (i.e. secondary lowering or hoisting gear) on furred ceiling, and the housing then passed through by curtain hangs on spool by steel wire rope, is realized the lifting of whole curtain by scroll roll.But on furred ceiling, motor is installed and spool is not easy very much, and the equipment such as motor and spool of purchasing needs suitable funds.
Summary of the invention
Installing and the problem of lifting to solve above-mentioned projection screen, this utility model provides a kind of Double-lifting electric screen, is to do some technological improvements on traditional electric screen.Make electric screen not only can realize curtain stretching out or retracting in electric screen housing, and the lifting of electric screen housing (whole electric screen) can be realized.Described Double-lifting, it is simply that refer to lifting and the curtain lifting in electric screen housing of electric screen self.
This utility model solves its technical problem and be the technical scheme is that
A kind of Double-lifting electric screen, mainly includes housing, motor, spool, curtain；Described motor, spool are installed in the housing, are provided with opening in the lower section of housing, as the outlet that curtain is flexible；Described curtain, upper end is fixed on spool；Described motor, for driving the rotation of spool.
Further, being designed with spool at the two ends of spool, spool is fixed on spool；The position that housing is corresponding above spool has circular hole；Being provided with again steel wire rope, one end of steel wire rope is fixed on spool, and the other end passes circular hole, is arranged on furred ceiling for connection.
The beneficial effects of the utility model are mainly manifested in: realize curtain lifting simultaneously and integral electric curtain lifts, low cost of manufacture, easy for installation.
Accompanying drawing explanation
Fig. 1 is the schematic appearance of a kind of embodiment of this utility model.
Fig. 2 is the internal structure schematic diagram of a kind of embodiment of this utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings a kind of embodiment of the present utility model is further described.
A kind of Double-lifting electric screen, as shown in Fig. 1 ~ 2, mainly includes housing 1, motor 2, spool 3, curtain 4；Described motor 2, spool 3 are installed within the case 1, are provided with opening in the lower section of housing 1, as the flexible outlet of curtain 4；Described curtain 4, upper end is fixed on spool 3, and lower end is provided with gag lever post 5；Described motor 2, its shaft links together with spool 3, for driving the rotation of spool 3.
Being respectively arranged at two ends with spool 6a, spool 6b at spool 3, spool 6a, 6b are fixed on spool 3；The position that housing 1 is corresponding above spool 6a, 6b has circular hole 7a, 7b；Being provided with again steel wire rope 8a, 8b, one end of steel wire rope 8a is fixed on spool 6a, and the other end is connected on one piece of installing plate 9a through circular hole 7a；One end of steel wire rope 8b is fixed on spool 6b, and the other end is connected on one piece of installing plate 9b through circular hole 7b.Described installing plate 9a, 9b, is respectively provided with two installing holes 10, passes for screw, be arranged on furred ceiling by installing plate.
Further, in order to improve safety, being respectively equipped with limit switch 11a, 11b on the side of two circular holes 7a, 7b, limit switch 11a, 11b control switch with the rising of electric screen and are connected；Limit switch 11a, 11b, be positioned at the top of housing 1.
Above-mentioned embodiment, working method is as follows: after installing plate 9a, 9b being arranged on furred ceiling by screw, and whole electric screen is hung thereon by steel wire rope 8a, 8b.When the control of electric screen switchs and is placed in " decline " gear, spool 3 rotates, and curtain 4 is slowly transferred from housing 1, and steel wire rope 8a, 8b slowly releases simultaneously, and whole electric screen also declines；After curtain 4 discharges, motor 2 shuts down, and whole electric screen also stops declining.When the control of electric screen switchs and is placed in " rising " gear, the anti-direction of spool 3 rotates, and curtain 4 is slowly retracted from housing 1, and steel wire rope 8a, 8b is slowly in spool 6a, 6b simultaneously, and whole electric screen also rises；After curtain 4 is retracted, motor 2 shuts down, and whole electric screen also stops rising.
Above-mentioned running, if close to furred ceiling is crossed or certain fault occurs to electric screen mounting distance in electric screen, when whole electric screen rises to furred ceiling soon, the most out-of-work；Now, limit switch 11a or 11b can be pressed into, disconnects the circuit that motor 2 rises, and stops continuing to rise, improves safety.
Above-described is only a kind of embodiment of the present utility model, it will be apparent to those skilled in the art that on the premise of without departing from this utility model principle, some changes made, all should be considered as belonging to protection domain of the present utility model.
