[0028] The inner magnetic transmission member 2 is adapted to the outer magnetic controller, which is not shown in the figure and is arranged on the outer curved glass. The outer magnetic controller is manually or electrically controlled to drive the magnetic column in the inner magnetic transmission member 5 to flip, thereby realizing magnetic transmission.

[0029] One side of the louver 1 is fixed in the vertical frame 4, and the other side is provided with a stretching and flipping shaft 10. The stretching and flipping shaft 10 passes through the flipping rope (ladder rope) of the louver 1. A louver beam 11 is provided outside the stretching and flipping shaft 10.

The upper and lower ends of the stretching and flipping shaft 10 are connected to the stretching flipper 6. The fixed end of the louver 1 is provided with a rope winder 12. The rope winder 12 is fixed on the transmission aluminum shaft 9 on the corresponding side. When the stretching flipper 6 performs a stretching action, the rope of the louver 1 is expanded and contracted.

[0030] The arc-shaped horizontal frame 3 is provided with a stretching flipper accommodating cavity 3.1 and a synchronous belt accommodating cavity 3.2 side by side. The stretching flipper 6 sleeved on one side of the synchronous belt 5 is arranged in the stretching flipper accommodating cavity 3.1, and the other side of the synchronous belt 5 is arranged in the synchronous belt accommodating cavity 3.2.

[0031] The stretching flipper 6 includes a base body 6.1, a flip gear shaft 6.2 and a friction bead 6.3. A synchronous belt mounting hole 6.1.1 is horizontally provided in the base body 6.1, and a gear shaft mounting hole 6.1.2 is vertically provided. The synchronous belt mounting hole 6.1.1 and the gear shaft mounting hole 6.1.2 are connected. The synchronous belt 5 passes through the synchronous belt mounting hole 6.1.1, and passes through the synchronous belt accommodating cavity 3.2 after being turned by the synchronous wheel shaft 8, so as to avoid interference between the synchronous belts on both sides moving in opposite directions, and ensure the smooth movement of the stretching flipper 6.

[0032] The flip gear shaft 6.2 is vertically inserted into the gear shaft mounting hole 6.1.2. The flip gear shaft 6.2 includes a gear 6.2.1 and a connecting shaft 6.2.2. The gear 6.2.1 is meshed with the synchronous belt 5. The connecting shaft 6.2.2 extends out of the seat body 6.1 and is connected to the stretching flip shaft 10. The connecting shaft 6.2.2 is radially provided with a limiting protrusion 6.2.3. The seat body 6.1 is provided with a stopper 6.1.3 corresponding to the limiting protrusion 6.2.3.

The synchronous belt 5 is meshed with the gear 6.2.1, driving the flip gear shaft 6.2 to rotate, and the limiting protrusion 6.2.3 on the flip gear shaft 6.2 rotates accordingly. When the limiting protrusion 6.2.3 is against the stopper 6.1.3, the flip gear shaft 6.2 is locked, and there is no relative movement between the flip gear shaft 6.2 and the synchronous belt 5. At this time, the synchronous belt drives the stretching flipper 6 to move as a whole, and the stretching flip shaft connected to the stretching flipper realizes the stretching function, driving the louver blades to stretch horizontally, and full shading and full lighting effects can be achieved as needed.

[0033] When semi-shading is needed, the transmission aluminum shaft 9 is rotated in the reverse direction, the flip gear shaft 6.2 is rotated in the reverse direction, the flip gear shaft 6.2 is unlocked, the flip gear shaft 6.2 drives the stretch flip shaft 10 to rotate, and the stretch flip shaft drives the flip rope of the louver to flip, and the angle is adjusted as needed to achieve a semi-shading effect.

[0034] A connecting shaft 6.2.2 is provided inside the gear 6.2.1, and a shaft stop cover 6.2.4 is provided outside. The outer end surface of the shaft stop cover is flush with the outer end surface of the seat body 6.1 to prevent foreign matter from entering the seat body and interfering with the meshing of the gear and the synchronous belt.

[0035] In order to improve the versatility of the seat body 6.1, two synchronous belt mounting holes 6.1.1 are arranged in parallel at the front and rear of the seat body 6.1, so that the seat body 6.1 can be installed forwards and backwards.

[0036] The outer side surface of the seat body 6.1 contacts the arc-shaped transverse frame 3 through elastic friction beads 6.3. The elastic friction beads 6.3 are embedded in the seat body 6.1. The seat body 6.1 is provided with an embedding groove 6.1.4. The elastic friction beads 6.3 have a built-in spring.

[0037] The two ends of the stretching and flipping shaft 10 are provided with hexagonal shaft holes, and the ends of the connecting shaft 6.2.2 of the flipping gear shaft 6.2 are provided with hexagonal columns corresponding to the hexagonal shaft holes to achieve synchronous rotation of the stretching and flipping shaft 10 and the flipping gear shaft 6.2.

[0038] The internal magnetic transmission component 2 includes a magnetic column 2.1, a non-magnetic isolation column 2.2, a plug 2.3, an inner sleeve 2.4 and an outer sleeve 2.5.

Plugs 2.3 are respectively provided at both ends of the inner sleeve 2.4, and the inner end surfaces of the plug 2.3 are respectively clamped with the corresponding magnetic columns 2.1.

[0039] The upper and lower end faces of the non-magnetic isolation column 2.2 are both provided with a connecting block 2.2.1, the end face of the magnetic column 2.1 close to the non-magnetic isolation column 2.2 is provided with a connecting slot 2.1.1 corresponding to the connecting block 2.2.1, the inner end face of the plug 2.3 is provided with a positioning block 2.3.1, and the end face of the magnetic column 2.1 close to the plug 2.3 is provided with a positioning slot 2.1.2 corresponding to the positioning block 2.3.1.

[0040] The magnetic column 2.1 is a cylindrical permanent magnet with a radial magnetic pole direction. Instead of the previous method of slotting the magnetic column surface for positioning (the magnetic lines of force are weakened at the slots and the magnetic force is lost), a slot is opened on the end surface of the magnetic column to fix the magnetic column while ensuring the magnetic strength of the magnetic column.

[0041] The plug 2.3 includes a plug-in shoulder 2.3.2, a limiting convex ring 2.3.3 and a bearing mounting shoulder 2.3.4. The plug-in shoulder 2.3.2 is inserted into the inner sleeve 2.4 and has an interference fit with the inner wall of the inner sleeve 2.4. The positioning block 2.3.1 on the inner side of the plug-in shoulder 2.3.2 is inserted into the positioning groove 2.1.2 of the magnetic column 2.1. The end face of the inner sleeve 2.4 is against the limiting convex ring 2.3.3. The bearing mounting shoulder 2.3.4 is coaxial with the plug-in shoulder 2.3.2. A bearing 2.6 is installed outside the bearing mounting shoulder 2.3.4. The plugs 2.3 installed at both ends of the inner sleeve 2.4 are connected to the outer sleeve 2.5 through the bearings 2.6. The bearings 2.6 and the outer sleeve 2.5 have an interference fit.

[0042] A connecting shaft hole is provided in the center of the bearing mounting shoulder 2.3.4, and the connecting shaft hole is connected to the transmission aluminum shaft 9 through a gearbox, so as to output a larger torque and a smaller rotation speed to the transmission aluminum shaft 9, thereby improving the bearing capacity and realizing the production of large-format and thick insulating glass.

[0043] Working principle: The external magnetic controller is manually or electrically controlled to drive the magnetic column 2.1 in the internal magnetic transmission part 2 to flip through magnetic transmission, and the magnetic column 2.1 drives the plug 2.3 and the transmission aluminum shaft 9 to rotate, and the transmission aluminum shaft 9 drives the synchronous wheel shaft 8 to rotate, and the synchronous belt 5 drives the stretching flipper 6 to move, and the stretching flipper 6 can realize the two functions of stretching and flipping; The synchronous belt 5 drives the flip gear shaft 6.2 to rotate, and the limit convex block 6.2.3 on the flip gear shaft 6.2 rotates accordingly. When the limit convex block 6.2.3 abuts against the stopper 6.1.3, the flip gear shaft 6.2 is locked, and there is no relative movement between the flip gear shaft 6.2 and the synchronous belt 5. At this time, the synchronous belt 5 drives the stretching flipper 6 to move as a whole, and the stretching flip shaft 10 connected to the stretching flipper 6 realizes the stretching function, driving the louver 1 to stretch horizontally, and the full shading and full lighting effects can be achieved according to needs; When semi-shading is needed, the transmission aluminum shaft 9 is rotated in the reverse direction, the flip gear shaft 6.2 is rotated in the reverse direction, the flip gear shaft 6.2 is unlocked, the flip gear shaft 6.2 drives the stretch flip shaft 10 to rotate, and the stretch flip shaft 10 drives the flip rope of the louver 1 to flip, and the angle is adjusted as needed to achieve a semi-shading effect.
