Detailed Description

The invention is described in further detail below with reference to the figures and the detailed description.

As shown in the drawings, the window covering provided by the embodiment comprises a first curtain cloth 21, a second curtain cloth 22 and a cylindrical air sleeve 12. The first cord fabric 21 and the second cord fabric 22 are overlapped to form an integral cord fabric layer 2, and a plurality of hooks 3 are arranged at the upper end of the cord fabric layer 2; the air jacket 12 is provided on the upper portion of the carcass layer 2.

The first curtain cloth 21 is ultraviolet-proof cloth, and the second curtain cloth 22 is cotton cloth; the ultraviolet-proof cloth and the cotton cloth are connected and fixed at least at the edge position through a separable connecting structure; ultraviolet-proof cloth includes base cloth layer 211 and coats in ultraviolet-proof coating 212 on base cloth layer 211, ultraviolet-proof coating 212 is located keeping away from of base cloth layer 211 on the side of cotton.

The connecting structure comprises a thread gluing, a button, a magnetic sheet or a magnetic strip. As shown in fig. 14, in the present embodiment, the connection structure is a

magnetic strip

4a, 4 b.

One end of the air sleeve 12 is closed, the other end of the air sleeve is connected with an air charging and discharging interface 13, and the air charging and discharging interface 13 is connected with an air pump (not shown in the figure) through a pipeline; at least both ends of the air jacket 12 are fixed to both ends of the carcass layer 2.

The curtain with the structure can be unfolded by inflating the air pump into the air sleeve 12, and the curtain can be folded by pumping out the air in the air sleeve 12 through the air pump.

In one embodiment of the window covering of the present invention, the air jacket 12 is a straight cylinder type, as shown in fig. 4. Of course, the air jacket 12 may have other forms, as shown in fig. 11, the air jacket 12 has a bellows shape; alternatively, as shown in fig. 12, the air jacket 12 is formed by connecting a plurality of circular air cells 12a in sequence along the axial direction, and the interiors of the adjacent circular air cells are communicated with each other. The air sleeve 12 having the above-described structure includes a plurality of wave crest portions 12b and a plurality of wave trough portions 12c, the wave crest portions 12b are large outer diameter portions, the wave trough portions 12c are small outer diameter portions, the plurality of wave crest portions 12b and the wave trough portions 12c are alternately distributed in the axial direction, and at least a part of the plurality of wave trough portions 12c is caught on the carcass layer 2 by the clips 130, respectively. As shown in fig. 3, the air jacket 12 is clamped between the first curtain 21 and the second curtain 22, the clip 130 is a U-shaped clip, the curtain 2 is provided with a through hole 20 for passing through two ends of the U-shaped clip, two ends of the U-shaped clip are respectively provided with a hook portion 13a, and the two hook portions 13a are hooked on a locking ring 11.

The air sleeve 12 with the structure can be used for stretching the side length under the action of air pressure during inflation, and can be retracted and shortened during air suction so as to drive the curtain to be folded. When the air sleeve 12 retracts, not only the two ends of the air sleeve 12 exert pull force on the window curtain in opposite directions, but also the force transmission can be realized at all the U-shaped clamping installation positions.

As a further improvement to the window covering of the present invention, as shown in fig. 4-10, a plurality of supporting members 14 are disposed inside the air jacket 12, and each supporting member 14 includes a cross bar 141; the adjacent cross bars 141 are connected through a connecting rod 15, one end of the connecting rod 15 is hinged to the left side of one of the cross bars 141, and the other end is hinged to the right side of the other cross bar 141; adjacent links 15 are connected to the same side of the same crossbar 141. Connecting rod 15 with horizontal pole 141's articulated position still is provided with torsional spring 16, the tip of connecting rod 15 is provided with shaft hole 15a, is provided with installation axle 141a on the

horizontal pole

141, and 16 one ends fixed mounting of torsional spring are on connecting rod 15, and other end fixed mounting is on horizontal pole 141, torsional spring 16 gives respectively connecting rod 15 and horizontal pole 141 with torsion, make connecting rod 15 with horizontal pole 141 has the trend that the contained angle reduces all the time. In one embodiment of the present invention, the supporting member 14 further comprises a ring 142, and the cross bar 141 is located at a diameter of the ring 142. Of course, in other embodiments, the supporting member 14 further includes two circular arcs 143, two circular arcs 143 are respectively located at two ends of the cross bar 141, and further, two auxiliary rods 144 are respectively connected to two ends of the two circular arcs 143, as shown in fig. 9 and 10.

Through the structure, when the air sleeve 12 retracts, as shown in fig. 8, the two adjacent supporting pieces 14 can be staggered with each other, so that the curtain can be supported, and the curtain can also present a relatively uniform folding effect when being folded, as shown in fig. 13.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
