[0028] A frame 10, on one side of the frame 10, a plurality of curtain sheets 11 are movably arranged, at the top of the frame 10, an installation box 12 is fixedly installed, and a wire reel is arranged in the installation box 12. Specifically, the curtain sheets 11 can be slidably arranged with the frame 10, and each curtain sheet 11 is fastened by a pull rope. A section of redundancy is left for the pull ropes between two adjacent curtain sheets 11. The electric wire reel in the installation box 12 winds and unwinds the pull ropes to realize the flipping and pulling as well as the sliding of each curtain sheet 11. The hollow position of the frame 10 is blocked by the inclined curtain sheets 11. The specific control method has been detailedly disclosed in the prior art and will not be elaborated herein. The curtain sheets 11 and the frame 10 can be made of PP by injection molding, having the characteristics of strong durability, not being easily weathered and long service life;

The frame 10 is detachably connected to the outer frame 13, and the frame 10 can be flipped around the outer frame 13; a connecting component is provided between the outer frame 13 and the frame 10 for limiting the frame 10. The connecting component includes a positioning hole 20, a protrusion 21 and a plug rod 30. A positioning hole 20 is opened at the top of the outer frame 13, and two positioning holes 20 are symmetrically opened at the bottom of the outer frame 13. The protrusion 21 is fixedly connected to the top of the frame 10 and is inserted into the positioning hole 20 at the top of the outer frame 13. Two plug rods 30 are elastically connected to the bottom of the frame 10, and the two plug rods 30 can be inserted into the two positioning holes 20 at the bottom of the outer frame 13. The outer frame 13 forms a rectangular frame structure, and the inner cavity size of the outer frame 13 is larger than that of the frame 10. A baffle is integrally formed at the top of the outer frame 13, and an installation hole is opened in the baffle. The positioning hole 20 forms a circular hole. The protrusion 21 is a cylindrical structure, and the protrusion 21 is integrally formed with the frame 10 and is adapted to the positioning hole 20;

[0030] In this solution, by setting the outer frame 13 and detachably connecting the frame 10 to the outer frame 13, it is convenient to remove the entire frame 10 and then clean each curtain sheet 11 one by one. Secondly, the protrusion 21 is aligned with the upper positioning hole 20 and inserted, and the two elastically connected plug rods 30 below are inserted into the corresponding positioning holes 20 to realize the installation of the frame 10 and the outer frame 13, which has the characteristics of convenient disassembly and assembly. For the two plug rods 30 below, one can be selected to be inserted into one positioning hole 20, and the other plug rod 30 is not inserted into the positioning hole 20. Then the frame 10 can rotate around the plug rod 30 inserted into the positioning hole 20. To ensure the stability of the rotation of the frame 10, the protrusion 21 is vertically aligned with one of the plug rods 30 below. On the basis of ensuring the disassembly and assembly of the frame 10 and the outer frame 13, the frame 10 can also be flipped open, which has a more flexible usage method. For the side of the curtain sheet 11 close to the window glass, the frame 10 can be rotated so that the curtain sheet 11 faces the interior, which is convenient for cleaning.

[0031] As Figure 5 and Figure 6 As shown, the connecting component further includes a cross beam 31 and a bolt 32. The cross beam 31 is fixedly connected to the frame 10, the bolt 32 is fixedly connected to the plug rod 30, and the plug rod 30 is elastically connected to the cross beam 31 through the bolt 32. The cross beam 31 forms a rod structure with a U-shaped cross section. A hole adapted to the bolt 32 is opened at the top of the cross beam 31, and the bolt 32 is slidably connected to the hole. A spring is provided below the cross beam 31, and the spring is sleeved outside the bolt 32. One end of the spring is fixedly connected to the bottom of the cross beam 31.

The top end of the plug rod 30 is fixedly connected to the bottom of the bolt 32;

[0032] In this solution, in order to achieve the elastic connection of the insertion rod 30, the spring is used to push the insertion rod 30 to drive the bolt 32 to move downward. The bolt 32 slides in the hole of the cross beam 31, and then the insertion rod 30 is inserted into the corresponding positioning hole 20. When disassembling and assembling the frame 10, only need to lift the two bolts 32 below, the operation is simple and fast, and it is flexible to use.

[0033] The working principle of the present utility model: The protrusion 21 is aligned with the upper positioning hole 20 and inserted. The two insertion rods 30 connected by elastic force below are inserted into the corresponding positioning holes 20 to realize the installation of the frame 10 and the outer frame 13, which has the characteristic of convenient disassembly and assembly. For the two insertion rods 30 below, one of them can be selectively inserted into a positioning hole 20, and the other insertion rod 30 is not inserted into the positioning hole 20. Then the frame 10 can rotate around the insertion rod 30 inserted into the positioning hole 20. In order to ensure the stability of the rotation of the frame 10, the protrusion 21 is vertically aligned with one of the insertion rods 30 below. On the basis of ensuring the disassembly and assembly of the frame 10 and the outer frame 13, the frame 10 can also be turned over and opened. In order to achieve the elastic connection of the insertion rod 30, the spring is used to push the insertion rod 30 to drive the bolt 32 to move downward. The bolt 32 slides in the hole of the cross beam 31, and then the insertion rod 30 is inserted into the corresponding positioning hole 20. When disassembling and assembling the frame 10, only need to lift the two bolts 32 below.
