Embodiment III:

as shown in fig. 14, the present embodiment is different from the first embodiment in that the lower cross frame in the present embodiment does not employ the slide frame 1, but uses only one U-shaped stopper rail instead of the slide frame 1. The sliding frame 1 as the upper transverse frame is mainly used for bearing the weight of the blade 2 and providing moving power, and the U-shaped limiting rail only provides a limiting effect and avoids the lower swing of the blade 2.

Fifth embodiment:

a folding door as shown in fig. 16 and 17, which adopts the shutter structure as described in any one of the first to fourth embodiments, and is formed by replacing the leaf 2 with a larger width of the leaf 7, since the width of the leaf 7 is much larger than that of the leaf 2, in this embodiment, only four leaves are installed, each leaf 7 is provided with a power shaft 21 and a turnover shaft 22 having the same structure and positional relationship as the leaf 2 so as to be able to cooperate with the sliding frame 1 and the like, the leaf 7 may be a conventional folding leaf with the addition of the power shaft 21 and the turnover shaft 22, both sides of the leaf are provided with waterproof strips 24 which are able to cooperate with each other, and the adjacent two leaves 7 are able to mutually press the waterproof strips 24 when closed to form a water blocking structure.

The shutter structure or the folding door provided in the above embodiment operates as follows, when the blades 2 (the door leaves 7) are in a stacked state, that is, all the blades 2 (the door leaves 7) are opened and are stacked close to one side of the wall hole, and the other side of the wall hole is completely opened, so that ventilation and sunlight enjoyment can be performed, or the blades can pass in and out. When the door needs to be closed, a driving motor is started, the driving motor drives a closed-loop chain 18 to rotate, the driving pulley 4a moves along with the first blade 2 (the door leaf 7), and because the steel cable 5 is fixedly connected to the blade pulley 4, when the steel cable 5 between the first blade 2 (the door leaf 7) and the second blade 2 (the door leaf 7) is tensioned due to the movement of the driving pulley 4a, the driving pulley 4a continuously moves and drives the second blade 2 (the door leaf 7) to move. Similarly, when the driving pulley 4a continues to move, all the blades 2 (door leaves 7) are gradually pulled away due to the action of the steel cable 5, so that the shutter effect is achieved, and the shutter structure can selectively switch off the driving motor. When the blade 2 (door leaf 7) is moving, the parallel wheels 23 corresponding to the blade 2 (door leaf 7) slide simultaneously in the U-shaped rail 15 (first, third, fourth and fifth embodiments), or the rod sleeve 13 corresponding to the blade 2 (door leaf 7) slides simultaneously on the slide rod 14 (second embodiment).

If the driving motor continues to operate to drive the driving pulley 4a to continue moving, at this time, since the turning shaft 23 of the first blade 2 (door leaf 7) and the last blade 2 (door leaf 7) are limited relative to the turning structure 12 and cannot move relative to the turning structure 12, the driving pulley 4a continues moving to pull the turning structure 12 along the guiding ramp 11 through the blade 2 (door leaf 7) to move and urge the blade 2 (door leaf 7) to turn and close, and meanwhile, the spring 6 is pressed to shorten (embodiment one, two, three and five) or elongate (embodiment four), at this time, one end of the steel cable 5 is fixedly connected to the frame material section bar or the sliding frame 1, so that the blade 2 (door leaf 7) cannot excessively move along with inertia, and the using effect is affected.

When the door needs to be opened, the driving pulley 4a is driven to move reversely, the driving pulley 4a drives the first blade 2 (the door leaf 7) to move reversely, the first blade 2 (the door leaf 7) does not tighten the overturning structure 12 any more, even the overturning structure 12 can be pushed to move reversely, the overturning structure 12 cooperates with the thrust of the first blade 2 (the door leaf 7) to move reversely along the guide inclined rail 11 under the action of the deformation restoring force of the resisting spring 6, and therefore the overturning opening of the blade 2 (the door leaf 7) is achieved, and the effect of a shutter is achieved. If the door is to be opened further, the driving pulley 4a is driven to move continuously, so that the driving pulley 4a sequentially pushes all the leaf pulleys 4 to move and drives the blades 2 (the door leaves 7) to be stacked on one side, and the stacking and opening effects are achieved. In practical application, the shutter structure can set the motor into two sections of operations, so that two effects of complete opening and shutter overturning can be realized, and the motor is set to continuously operate by the folding door, so that only two effects of opening and closing the door are realized. When the shutter structure or the folding door is completely closed, the automatic locking can be realized by using a motor with a lock, or a door and window lock is additionally arranged to lock the blade 2 (the door leaf 7).

The foregoing examples illustrate only a few embodiments of the utility model and are described in detail herein without thereby limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
