The second embodiment:

the difference between the present embodiment and the first embodiment lies in that the U-shaped rail 15 as the limiting structure 12 is changed into the sliding rod 14, all the parallel shafts 22 are limited by the sliding rod 14 to move synchronously in the direction perpendicular to the extending direction of the sliding frame 1, as shown in fig. 9, the limiting structure 12 is the sliding rod 14 arranged in parallel with the sliding frame 1, the parallel shafts 22 of the blades 2 are connected to the sliding rod 14 in a sliding manner through the rod sleeve 13, the sliding rod 14 is connected to the guide oblique rail 11 in a sliding manner through the lifting pulley 3, in order to avoid influencing the sliding of the rod sleeve 13 on the sliding rod 14, only one fixing sleeve is mounted at each end of the sliding rod 14, and then the mounting substrate 31 is riveted through 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 sleeve 14.

Example three:

the difference between this embodiment and the first embodiment is that the structure of the U-shaped rail 15 is modified so that when the last blade 2 is pulled, the parallel wheel 23 of one of the blades 2 except the first and last blades 2 is limited relative to the U-shaped rail 15 in the direction of pulling the blades 2 apart. As shown in fig. 10-12, an inner wall of the U-shaped rail 15 on a side away from the opening is provided with a shaft groove 151 matching with the parallel shaft 22 for sliding, an outer side of the U-shaped rail 15 opposite to the opening is provided with a positioning groove 152 corresponding to the shaft groove 151, the positioning groove 152 is provided with a bolt hole at a corresponding position in front of the parallel shaft 22 of the eighth blade 2 when all the blades 2 are completely pulled apart (when the last blade 2 is pulled), a limit bolt 153 is connected to the bolt hole by screw threads, and the limit bolt 153 is inserted into the shaft groove 151, in practical application, a self-tapping screw can be directly screwed into the shaft groove 151 on the positioning groove 152 by positioning of the positioning groove 152, in order to be parallel to the forces, the eighth blade 2 of the fourteen blades 2 is selected to be installed with the elongated parallel shaft 22, so that the parallel shaft 22 of the eighth blade 2 can pass through the parallel wheel 23 and extend into the shaft groove 151, and when the last blade 2 is pulled, the parallel shaft 22 extending into the shaft groove 151 and the limit bolt 153 can slide the U-shaped rail 15 continuously.

Example four:

the difference between this embodiment and the first embodiment is that the guide ramp 11 and the U-shaped rail 15 are both arranged above the sliding area, and correspondingly the parallel shaft 22 of the blade 2 is also arranged above the power shaft 21, and the U-shaped rail 15 is pressed downwards under the guidance of the guide ramp 11 by the continued movement of the fully opened blade 2, thereby effecting the turning-over closure of the blade 2. In practical application, an extension structure can be added in the blade 2, so that the swing space of the blade 2 is increased, and the limit structure 12 and the guide inclined rail 11 are convenient to install.

The shutter structure provided in the above embodiment operates such that when the blades 2 are stacked (i.e., all the blades 2 are turned down and stacked close to each other on one side of the wall opening), the other side of the wall opening is completely opened, so that ventilation and sunlight can be provided. When needing to close, start driving motor, driving motor drives closed loop chain 18 and rotates, and the removal is followed and is driven first blade 2 to remove to initiative coaster 4a, because fixedly connected with steel cable 5 on coaster 4, when the removal of initiative coaster 4a made the steel cable 5 between first blade 2 and the second blade 2 taut, the removal of initiative coaster 4a continued to be removed can drive the removal of second blade 2 simultaneously. Similarly, when the driving pulley 4a continues to move, all the blades 2 are gradually pulled apart by the action of the cable 5, so as to form the effect of the shutter, and the driving motor can be selectively turned off. When the blade 2 is moving, the parallel wheels 23 corresponding to the blade 2 will slide in the U-shaped rail 15 at the same time (embodiments one, three and four), or the rod sleeve 13 corresponding to the blade 2 will slide in the sliding rod 14 at the same time (embodiment two).

If the driving motor continues to operate, the driving pulley 4a is driven to continue to move, at this time, because the parallel shaft 23 of the first blade 2 and the last blade 2 (in the third embodiment, the eighth blade 2 is also limited relative to the limiting structure 12 and cannot move relative to the limiting structure 12, the driving pulley 4a continues to move, through the blade, the limiting structure 12 is pulled to move along the guide inclined rail 11 and cause the blade 2 to turn over and close, at this time, because one end of the steel cable 5 is fixedly connected to the frame material section bar or the sliding frame 1, the blade 2 cannot excessively move along with inertia, and the use effect is affected.

When needing to open, drive initiative coaster 4a antiport, initiative coaster 4a drives first blade 2 antiport, and first blade 2 no longer strains limit structure 12 and can promote limit structure 12 antiport even, and limit structure 12 cooperates the thrust of first blade 2 under the effect of gravity and can follow direction ramp 11 antiport to realize that the upset of blade 2 is opened, formed the effect of tripe. If the blade needs to be further opened, the driving pulley 4a is continuously driven to move, so that the driving pulley 4a sequentially pushes all the blade pulleys 4 to move, and drives the blades 2 to be stacked to one side, and the effect of stacking and opening is achieved. In practical applications, the power shaft 21 of the vane 2 may be eccentrically disposed, so that the vane 2 may be inclined downward in a natural state, so as to provide a certain power for the reverse movement of the limiting structure 12 when the vane is turned over and opened.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
