Abstract

본 발명은 전동스크린 장치등 외부동력에 의해 구동되어 원통형 롤바 외면에 감기거나 풀리도록하는 스크린이 원통형 롤바로 부터 풀려 펼쳐진 스크린에 감기는 방향측으로 향상 긴장력을 부여함으로써 스크린면을 항상 팽팽하게 유지한 상태에서 사용할수 있게한 것으로서, 외면에 스크린(1)이 부착고정되어 롤식으로 감기거나 풀리도록 한 외통(2)의 일측을 브라케트(3)에 회동가능하게 지지하고, 상기 외통(2)의 타측에는 구동원과 연결되어 브라케트(3)에 회동가능하게 지지하고,상기 외통(2)의 타측에는 구동원과 연결되어 브라케트(3)에 회전가능하게 지지하는 연결축(4)을 베어링(5)을 개재하여 삽입설치 하고, 상기 연결축(4)의 선단 소경부(6)는 상기 외통(2)의 내부에서 고정구(7)로서 고정설치되는 내통(8)의 선단에 베어링(9)을 개재하여 조립설치 되며, 상기 내통(8)의 선단에 베어링(9)을 개재하여 조립설치 되며, 상기 내통(8)의외면에는 일단이 상기 고정구(7)에 부착고정되고 타단은 상기 연결축(4)의 플랜지부(10)에 부착고정되는 코일스프링(11)을 외감하여서 되는 것을 특징으로 하는 텐션기능을 갖는 원통형 롤바(A)이다.The present invention maintains the screen surface at all times by applying an improved tension to the direction in which the screen driven by external power such as an electric screen device to be wound or unrolled on the outer surface of the cylindrical roll bar is wound on the unrolled screen unrolled from the cylindrical roll bar As can be used in, the one side of the outer cylinder (2) is fixed to the bracket (3) rotatably supported by the bracket (3) so that the screen (1) attached to the outer surface is rolled or unrolled, the other of the outer cylinder (2) On the side is connected to the drive source to support the bracket 3 rotatably, the other side of the outer cylinder (2) is connected to the drive source connected to the drive shaft (4) rotatably supporting the bearing (3) The small diameter portion 6 of the front end of the connecting shaft 4 is interposed between the bearing 9 at the end of the inner cylinder 8 which is fixedly installed as the fastener 7 inside the outer cylinder 2. To be assembled And, the front end of the inner cylinder (8) is assembled and installed via a bearing (9), one end is fixed to the fixing member (7) on the outer surface of the inner cylinder (8) and the other end of the plan of the connecting shaft (4) It is a cylindrical roll bar (A) having a tension function, characterized in that the coil spring (11) attached to the branch (10) is wound around.
