Example 2

Most of the structures in this embodiment are the same as those in embodiment 1, and the description of the same parts is omitted. The present embodiment is different from embodiment 1 in that: when the area covered by the roller shutter system is large and larger pulling force is needed, 2 pneumatic rods 8 are arranged in the constant tension mechanism in parallel, so that the constant pulling force output by the constant tension mechanism is 2 times of the original constant pulling force.

The utility model discloses three kinds of operating condition have:

opening the roller shutter: the roll pipe 1 is rotated in a reverse direction by the driving of the tubular motor, so that the roll screen cloth 2 which is originally tightly wound around the roll pipe 1 is slowly released. The telescopic rod of the pneumatic rod 8 in the traction rod 3 retracts inwards, and the constant pulling force output by the pneumatic rod 8 acts on the roller shutter cloth 2 to stretch the roller shutter cloth 2 downwards and keep the roller shutter cloth in a tight state. When the roll screen 2 reaches the set position, the tubular motor stops.

Rolling up the roller shutter: under the drive of the tubular motor, the roller pipe 1 rotates forward to form an upward pulling force, and the lifting rod of the pneumatic rod 8 in the traction rod 3 extends outwards. When the upward pulling force output by the tubular motor is larger than the downward pulling force output by the pneumatic rod 8, the roller pipe 1 rotates in the positive direction to wind the roller cloth 2 on the outer part of the roller cloth until the tubular motor stops running. In this state, the upward pulling force received by the roller shutter cloth 2 is greater than the downward pulling force, so that the roller shutter cloth 2 is always kept in a tightened state.

A static state: at this time, the tube-rotating motor in the roll tube 1 does not operate, the raising and retracting rod of the pneumatic rod 8 keeps outputting a constant pulling force, and the pulling force acts on the roll screen cloth 2, so that the roll screen cloth 2 is in a tightened state.

The utility model discloses a performance is excellent in anti-wind pressure, and simple structure through mount pad and installation face fixed connection, easily installs, and installs shared area little, is particularly useful for installing in the outer solar shading system that facade outside the wall body, top surface, the narrow and small region in space and the large tracts of land was laid.
