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 underwind electric screen, comprises curtain 31, and also comprise the framework 1 being positioned at top, this framework 1 can be assembled by square tube, for the upper end of fixing curtain 31 and each parts of electric screen.If length needs, multiple framework can also be made to connect in the longitudinal direction, such as, adopt screw 3 to be fixed connection.Fix left shaft holder 15, right bearing seat 28 respectively at the two ends of framework 1, this left shaft holder 15, right bearing seat 28 can be tabular, are arranged on framework 1 by contiguous block 17, such as, screw can be adopted to be fixed.
Also comprise for drive motor 25, described motor 25 is fixedly mounted on bracing frame 13, and this bracing frame 13 can directly be fixed on framework 1, and the lead-in wire 8 of motor exposes, and also can be fixedly mounted on the sidewall of left shaft holder 15.The output terminal of described motor 25 passes left shaft holder 15 by bearing 22, and extend in sleeve pipe 4, is coaxially fixedly connected with sleeve pipe 4.The output terminal of motor 25 is arranged on left shaft holder 15 by bearing 22, and the outer ring of such as bearing 22 and left shaft holder 15 interference fit, the inner ring of bearing is together with the output terminal interference fit of motor 25.In another embodiment, for the ease of installing, can also fix an idle wheel 23 on the outer wall of the output terminal of motor 25, this idle wheel 23 is arranged on left shaft holder 15 by bearing 22.The output terminal of motor 25 is also fixedly connected with sleeve pipe 4, make sleeve pipe 4 can under the driving of motor 25 synchronous axial system.In the utility model embodiment, the termination of described motor 25 output terminal is provided with driving wheel 26, and this driving wheel 26 extend in the inner chamber of sleeve pipe 4, and together with the inner chamber interference fit of sleeve pipe 4.
The other end of described sleeve pipe 4 is connected with right bearing seat 28 by bearing 29; Sleeve pipe 4 and right bearing seat 28 are rotatably connected.Preferably, install an engaged wheel 30 in the termination of sleeve pipe 4, the rotating shaft of this engaged wheel 30 is arranged in right bearing seat 28 by bearing 29.
