[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-3 In this embodiment, a retractable and foldable curtain structure includes a curtain 1, a concave plate 3 and a vertical plate 2 are respectively fixed to the left and right ends of the curtain 1, and a cover plate 4 is clamped at the upper and lower ends of the vertical plate 2. A retracting component for retracting the curtain 1 is provided inside the vertical plate 2, and a sticky material such as an adhesive sticker is fixed to the side of the concave plate 3 opposite to the vertical plate 2, so that the curtain 1 can be installed on the window without punching.

[0026] See also Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 The contraction component in this embodiment includes a placement seat 8 fixed to the right wall of the inner cavity of the vertical plate 2, a cover bin 9 is clamped on the left side of the placement seat 8, four insertion rods 10 are fixed to the left side of the placement seat 8, the outer surfaces of the two inner insertion rods 10 are sleeved with T-shaped placement blocks 11, the outer surface of the T-shaped placement block 11 is sleeved with a torsion spring 12, the outer surfaces of the two outer insertion rods 10 are sleeved with a placement table 13, the outer surface of the placement table 13 is wrapped with a pull rope 15, two retaining rings 14 are fixed to the left side of the placement seat 8, and the contraction component also includes a guide component arranged inside the vertical plate 2 for guiding the pull rope 15.

[0027] The curtain 1 is composed of a plurality of curtain cloths, and circular holes for the pull cords 15 to pass through are provided at the upper and lower ends of the curtain cloths, so that the two pull cords 15 can pass through the outside of the plurality of curtain cloths, so that the pull cords 15 can pull the plurality of curtain cloths to shrink and fold them.

[0028] In addition, one end of the pull cord 15 away from the placement table 13 is fixed to the inner wall of the concave plate 3, so that the two pull cords 15 are fixed to the concave plate 3, so that when the curtain is contracted and folded, the two pull cords 15 can pull multiple curtain fabrics to contract and fold. Two through holes for the pull cords 15 to pass through the interior are opened on the left side of the vertical plate 2, so that the two pull cords 15 can pass through the outside of the vertical plate 2, so that the pull cords 15 can pass through to the outside of the curtain 1 and be connected and fixed to the concave plate 3.

[0029] In addition, the left side of the T-shaped placing block 11 and the placing platform 13 are provided with a socket for them to be sleeved on the outer surface of the insertion rod 10, so that the T-shaped placing block 11 and the placing platform 13 can be placed on the placing seat 8 by being sleeved on the outer surface of the insertion rod 10, and a baffle is fixed on the left side of the placing seat 8 so as to isolate the T-shaped placing blocks 11 and the placing platform 13 at the upper and lower ends, which can effectively prevent the torsion springs 12 and the pull rope 15 at the upper and lower ends from being entangled.

[0030] At the same time, both upper and lower ends of the cover bin 9 are provided with connecting holes for the pull ropes 15 to pass through. When the cover bin 9 is fixedly connected to the placement seat 8, the two pull ropes 15 can pass through the inside of the cover bin 9 through the connecting holes.

[0031] Moreover, the two outer plug rods 10 are located on the inner side of the baffle ring 14 so that the baffle ring 14 can block the pull rope 15. The outer surface of the baffle ring 14 is provided with three connecting holes for the pull rope 15 to pass through. The pull rope 15 passes through the outside of the connecting holes, which makes it easy for the pull rope 15 to pass through the outside of the baffle ring 14 and pass through the interior of the cover bin 9.

[0032] In addition, the placement table 13 is composed of three round blocks and two vertical blocks, the pull rope 15 is wound around the outer surface of the right vertical block, and the end of the torsion spring 12 away from the T-shaped placement block 11 is fixed to the outer surface of the left vertical block, which can isolate the torsion spring 12 from the pull rope 15, and can effectively prevent the torsion spring 12 and the pull rope 15 from being entangled together, and when the curtain 1 is unfolded to be retracted and folded, the torsion spring 12 can drive the placement table 13 to rotate, so that the placement table 13 can reel in the pull rope 15.

[0033] See also Figure 3-4 The guide assembly in this embodiment includes two brackets 5 fixed to the inside of the vertical plate 2, and the brackets 5 are internally rotatably connected to the guide wheels 6. The guide assembly also includes two iron blocks 7 fixed to the front and rear ends of the vertical plate 2.

[0034] Secondly, the bracket 5 is composed of two horizontal blocks and two vertical blocks, and the two ends of the guide wheel 6 are rotatably connected to the side opposite to the two vertical blocks through bearings, which is convenient for the pull rope 15 to pass through the outside of the bracket 5, so that the guide wheel 6 can guide the pull rope 15, and the opposite side of the two iron blocks 7 in the same group are also respectively abutted against the opposite side of the two vertical blocks.

[0035] The working principle of the above embodiment is:

[0036] When in use, when the curtain 1 needs to be installed on the window, an adhesive sticker is attached to the side opposite to the vertical plate 2 of the concave plate 3. After the concave plate 3 is installed, the vertical plate 2 is installed on the other side of the window. When the user drives the vertical plate 2 to move, the two pull cords 15 are released under the action of tension and the placement table 13 is driven to rotate, so that the torsion spring 12 can be rolled up during the rotation of the placement table 13, so that the curtain 1 can be unfolded and the vertical plate 2 can also be installed on the other side of the window. When shrinking and folding, by removing the vertical plate 2, the two torsion springs 12 can drive the two placement platforms 13 to rotate in another direction under the elastic force of the two torsion springs 12, so that the torsion springs 12 are no longer wrapped around the placement platforms 13 and are gradually wrapped around the T-shaped placement block 11. At the same time, when the torsion springs 12 drive the placement platform 13 to rotate, the placement platform 13 reels in the pull rope 15, so that the two pull ropes 15 pull the multiple curtain fabrics to shrink and fold, so as to complete the shrinkage and folding of the curtain 1, and there is no need to use external tools to tie it up.
