The second embodiment:

the difference between this embodiment and the first embodiment is that the U-shaped rail 15 as the turnover structure 12 is changed into the sliding rod 14, and the sliding rod 14 limits all turnover shafts 22 to move synchronously in the direction perpendicular to the extending direction of the sliding frame 1, as shown in fig. 13, the turnover structure 12 is the sliding rod 14 arranged in parallel with the sliding frame 1, the turnover shaft 22 of the blade 2 is connected to the sliding rod 14 by the rod sleeve 13 in a sliding manner, the sliding rod 14 is connected to the guide oblique rail 11 by the guide pulley 3 in a sliding manner, in order to avoid affecting the sliding of the rod sleeve 13 on the sliding rod 14, only one fixing sleeve is arranged at each end of the sliding rod 14, and then the mounting base plate 31 is riveted by the fixing sleeve, the rod sleeve 13 corresponding to the first blade 2 touches the fixing sleeve at one end of the blade 2 for limiting when the blade 2 is completely pulled open, and the rod sleeve 13 corresponding to the last blade 2 is also fixedly mounted on the sliding rod 14; similarly, only two resisting springs 6 are provided in the present embodiment, and two corresponding sliding seats 63 are respectively mounted on the fixing sleeves at the two ends of the sliding rod 14.

Example three:

as shown in fig. 14, the difference between the first embodiment and the second embodiment is that the lower horizontal frame in the present embodiment does not use the sliding frame 1, but only uses a U-shaped limit rail instead of the sliding frame 1. The sliding frame 1 as the upper transverse frame bears the weight of the blade 2 and provides moving power, and the U-shaped limit rail only provides a limit function to avoid the lower part of the blade 2 from swinging. Compared with the first embodiment, the lower transverse frame has the advantages that the size is smaller, the occupied space is smaller, the appearance is more attractive, and the possibility of tripping people can be reduced.

Example four:

as shown in fig. 15, the present embodiment is different from the first embodiment in that a spring seat 61 and an associated structure such as a resisting spring 6 are installed at the other side of the flip structure 12, the resisting spring 6 is elongated when the flip structure 12 slides to approach the sliding area, and a tensile force resisting the sliding of the flip structure 12 to the sliding area is provided by restoring the deformation of the resisting spring 6 to be shortened.

Example five:

as shown in fig. 16 and 17, a folding door is formed by adopting the louver structure according to any one of the first to fourth embodiments, and replacing the blades 2 with the door leaves 7 having a larger width, because the width of the door leaves 7 is much larger than that of the blades 2, in this embodiment, only four door leaves are installed, each door leaf 7 is provided with a power shaft 21 and a turning shaft 22 having the same structure and position relationship with the blades 2, so as to be matched with the sliding frame 1 and other structures, the door leaves 7 can be a conventional folding door leaf, and the power shaft 21 and the turning shaft 22 are added, two sides of each door leaf are provided with waterproof rubber strips 24 capable of being matched with each other, and when two adjacent door leaves 7 are closed, the waterproof rubber strips 24 can be mutually pressed 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 the stacked state, that is, all the blades 2 (the door leaves 7) are opened and stacked on one side of the wall opening, and the other side of the wall opening is fully opened, so that ventilation and sunlight enjoyment can be performed, or passing through can be performed. When the blade is required to be closed, the driving motor is started, the driving motor drives the closed-loop chain 18 to rotate, the driving pulley 4a moves along with the driving pulley and drives the first blade 2 (the door leaf 7) to move, and due to the fact that the steel cable 5 is fixedly connected to the blade pulley 4, when the driving pulley 4a moves to enable the steel cable 5 between the first blade 2 (the door leaf 7) and the second blade 2 (the door leaf 7) to be tensioned, the driving pulley 4a continues to move and can drive the second blade 2 (the door leaf 7) to move at the same time. Similarly, when the driving pulley 4a continues to move, all the blades 2 (door leaves 7) are gradually pulled apart by the action of the cable 5, so as to form the effect of the shutter, and the shutter structure can selectively close the driving motor. When the blade 2 (door leaf 7) moves, the parallel wheels 23 corresponding to the blade 2 (door leaf 7) can simultaneously slide in the U-shaped rail 15 (embodiments one, three, four and five), or the rod sleeve 13 corresponding to the blade 2 (door leaf 7) can simultaneously slide on the sliding rod 14 (embodiment two).

If the driving motor continues to operate, the driving pulley 4a is driven to continue to move, at this time, because the turning shaft 23 of the first blade 2 (the door leaf 7) and the last blade 2 (the door leaf 7) is limited relative to the turning structure 12 and cannot move relative to the turning structure 12, the driving pulley 4a continues to move, through the blade 2 (the door leaf 7), the turning structure 12 is pulled to move along the guide inclined rail 11 and drive the blade 2 (the door leaf 7) to turn over and close, and meanwhile, the resisting spring 6 is pressed to shorten (embodiment one, two, three and five) or elongate (embodiment four), at this time, because one end of the steel cable 5 is fixedly connected to the frame section or the sliding frame 1, the blade 2 (the door leaf 7) cannot excessively move along with inertia, and the use effect is affected.

When needing to open, the reverse motion of drive initiative coaster 4a, initiative coaster 4a drives first blade 2 (door leaf 7) reverse motion, first blade 2 (door leaf 7) no longer strains flip structure 12 and can promote flip structure 12 reverse motion even, flip structure 12 can follow direction ramp 11 reverse motion in the thrust of the first blade 2 of the cooperation (door leaf 7) under the effect of the deformation restoring force of resisting spring 6 to realize that the upset of blade 2 (door leaf 7) is opened, the effect of tripe has been formed. If the leaf blades need to be further opened, the driving pulley 4a is continuously driven to move, so that the driving pulley 4a sequentially pushes all the leaf pulleys 4 to move, and drives the leaf blades 2 (the leaf blades 7) to be stacked to one side, and the effect of stacking and opening is achieved. In practical application, the shutter structure can set the motor to operate in two sections, so that two effects of completely opening and shutter overturning can be realized, and the folding door sets the motor to operate continuously, so that only two effects of opening and closing the door can be realized. When the shutter structure or the folding door is completely closed, 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 above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
