  • Patent number: 7995274
    Abstract: An electric projector screen is revealed. A linkage member is sleeved in a winding tube in a fixed seat and a locator is fixed on the winding tube. An interlock pipe mounted with a connection part therein is arranged between the linkage member and the locator. The interlock pipe and the connection part are corresponding to each other for location. An output end of a motor in the interlock pipe is connected to the connection part while the other end of the motor is arranged with a fastening plate. The cover has limit holes corresponding to the locator so that the locator is pressed tightly by stoppers passing through the limit holes. Thus the screen fabric is located and limited during motor maintenance and replacement and damages caused by sudden opening of the screen fabric are prevented. The motor maintenance and replacement become easier and more convenient.
