[0019] The present invention is described in detail below with reference to the embodiments. Example 1
[0020] Figure 1 Schematic diagram of the cross-sectional structure of the rotating shutter in this embodiment. Figure 2 for Figure 1 A schematic diagram of the structure of the rotary shutter of this embodiment is as follows: Figure 1 , 2As shown, it includes a main profile 1 and a sealing accessory 2. The main profile 1 in this embodiment is a straight-plate thermally-broken profile, which is a profile formed by rolling two strip-shaped plates with thermal insulation strip snap-in 15 to relatively snap-in thermal insulation strip 14 into one piece. An L-shaped side panel 11 is vertically extended from both sides of the main profile 1 to the front, and the two L-shaped side panels 11 relatively form a glass snap-in 12. Open screw holes 133, 134 and wide-mouthed wedge-shaped grooves 135, 136 are symmetrically arranged on the back of the main profile 1; the wedge-shaped grooves 135, 136 are arranged on the outside of the screw holes 133, 134, and the openings of the screw holes 133, 134 are in the same direction as the openings of the wedge-shaped grooves 135, 136. The main body of the sealing connector is a profile with a U-shaped cross section, and a wedge-shaped protrusion 211 and a boss 212 are arranged on the bottom surface thereof, and the wedge-shaped protrusion 211 and the boss 212 are respectively matched and plugged with the wedge-shaped groove 135 and the screw hole 133; one side of the U-shaped groove of the sealing connector is an L-shaped side 223 with an L-shaped cross section, and the other side is a T-shaped side 220 with a T-shaped cross section. The sealing connectors are two identical ones, and are plugged into the back of the main profile 1 with T-shaped sides in a nearly symmetrical manner. The two sealing connectors each have a U-shaped groove 218, 219. A sealing strip clamping groove 217 is formed between the T-shaped sides of the two sealing connectors. The cross section of the sealing strip 23 is a rectangular shape, and grooves 231, 232 are horizontally arranged on the two side walls thereof, and the width of the bottom of the grooves 231, 232 is greater than the horizontal side thickness of the T-shaped side 220 and the horizontal side thickness of the L-shaped side 223. The grooves 232 and 231 of the sealing strip 23 are respectively movably engaged with the horizontal sides of the T-shaped side and the horizontal sides of the L-shaped side 223. The sealing strips 24 and 25 are respectively arranged in the U-shaped groove 219 and the sealing strip engaging groove 217. The bottoms of the sealing strips 23, 24, and 25 are respectively provided with elastic bodies 3, and the sealing strips are movably and elastically pressed with the U-shaped groove 219 and the sealing strip engaging groove 217.
[0021] Figure 3 FIG. 2 is a schematic diagram of the sealing state of the transverse profile of the rotating shutter in this embodiment. Figure 3As shown, when the transverse profile of the invention for rotating and opening the Venetian blind is used as the transverse profile of the window frame and the window sash at the same time, the sealing performance of the window is very good. At this time, the transverse profile 4 of the window frame and the transverse profile 5 of the window sash are connected by the rotating shaft 6, and the glass is installed in the glass bayonet 12 to form a rotating and opening Venetian blind. During installation, the sealing strip 26 in the transverse profile 4 of the window frame and the sealing strip 23 in the transverse profile 5 of the window sash are pressed against each other by the action of the elastic body 3. When the sealing strip 23 is sealed, since the width of the groove 231 of the sealing strip 23 is greater than the transverse thickness of the T-shaped side and the L-shaped side 223 of the U-shaped groove, the sealing strip 23 is elastically pressed up and down in the U-shaped groove, and other sealing strips are also elastically pressed in this way. This makes the sealing performance of the window frame and the window sash good, and is particularly suitable for rotating and opening Venetian blinds. The transverse profile in this embodiment is a thermal-break profile. The window frame and the window sash both use thermal-break profiles with thermal insulation strips, which are more conducive to blocking the heat conduction between indoor and outdoor, and more energy-saving. In the transverse profile of this embodiment, the main profile 1 and the sealing accessory 2 are connected by wedge-shaped protrusions and bosses, and the connection is more firm. Example 2

The sealing accessory includes a sealing connector and a sealing strip 23. The sealing connector is a card plate 213, 214 symmetrically inserted into the two wedge-shaped grooves 135, 136, the ends of the card plates 213, 214 are bent vertically toward each other to form side edges 215, 216, and a sealing strip card groove 217 is formed between the two card plates 213, 214; the cross-section of the sealing strip 23 is rectangular, and grooves 231, 232 are arranged on its two side walls along the length direction, the width of the grooves 231, 232 is greater than the thickness of the side edges 215, 216, and the grooves 231, 232 are movably engaged with the side edges 215, 216; an elastomer 3 is arranged at the bottom of the sealing strip card groove 217, and the sealing strip 23 and the elastomer 3 are movably and elastically crimped.
[0023] The method of using the transverse profile of the rotating shutter in this embodiment is the same as that in Example 1. The difference is that the sealing strip in this embodiment is a wider whole strip, and the use of such a sealing strip is convenient for installation. When the transverse profile of the rotating shutter in this embodiment is used, since the width of the grooves 231 and 232 of the sealing strip 23 is greater than the thickness of the side edges 215 and 216, the grooves 231 and 232 are movably engaged with the side edges 215 and 216; the width of the groove 231 is greater than the thickness of the horizontal side of the side edges 215 and 216, and the sealing strip 23 and the elastic body 3 are movably elastically pressed. When used as a transverse profile of the rotating shutter window frame and window sash, the sealing performance is good. Example 3
[0024] Figure 6 Schematic diagram of the cross-sectional structure of the rotating shutter in this embodiment. Figure 7 for Figure 6 A schematic diagram of the structure of the rotary shutter of this embodiment is as follows: Figure 6 , 7As shown, it comprises a main body profile 1 and a sealing accessory 2, wherein the main body profile 1 is a straight plate, and an L-shaped side plate 11 is vertically extended from both sides of the main body profile 1 to the front, and the two L-shaped side plates 11 are opposite to form a glass bayonet 12. On the back of the main body profile 1, an elastic body card slot 13 is longitudinally arranged in the middle, and the outlet of the elastic body card slot 13 is provided with opposite convex ridges 131, 132, and the two sides of the elastic body card slot 13 are respectively provided with open screw holes 133, 134 and wedge-shaped grooves 135, 136 with large openings facing outwards; the wedge-shaped grooves 135, 136 are arranged on the outside of the screw holes 133, 134, and the openings of the screw holes 133, 134 are in the same direction as the openings of the wedge-shaped grooves 135, 136. The main body of the sealing connector is a profile with a U-shaped cross section, and a wedge-shaped protrusion 211 and a boss 212 are arranged on the bottom surface thereof, and the wedge-shaped protrusion 211 and the boss 212 are respectively matched and plugged with the wedge-shaped groove 135 and the screw hole 133; one side of the U-shaped groove of the sealing connector is an L-shaped side 223 with an L-shaped cross section, and the other side is a T-shaped side 220 with a T-shaped cross section. The sealing connectors are two identical ones, and are plugged into the back of the main profile 1 with the T-shaped sides symmetrically, and the two sealing connectors each have a U-shaped groove 218, 219. A sealing strip card groove 217 is formed between the T-shaped sides of the two sealing connectors; the sealing strip card groove 217 is connected to the elastic body card groove 13.

The bottom of the sealing strips 23, 24, and 25 is respectively provided with an elastic body 3, and the sealing strips are movably and elastically pressed with the U-shaped groove 219 and the sealing strip clamping groove 217.
[0025] The method of using the transverse profile of the rotating shutter in this embodiment is the same as that in the first embodiment. Since the width of the groove 231 of the sealing strip 23 is greater than the transverse thickness of the T-shaped side 220 and the L-shaped side 223, the sealing strip 23 is elastically pressed up and down in the U-shaped groove 218, and other sealing strips are also elastically pressed in this way. This makes the sealing performance of the window frame and the window sash good, and is particularly suitable for rotating shutters.
