[0030] Example 1
[0031] like Figure 1 As shown, a sandwich-structured insulated door curtain includes a left curtain body 10, a right curtain body 20, and a closing body 30. Insulation cotton 12 is sandwiched inside both the left curtain body 10 and the right curtain body 20. The surface layer of the left curtain body 10 and the right curtain body 20 is a wear-resistant and waterproof layer, which is distributed on both sides of the insulation cotton 12 to protect the internal insulation cotton 12. The insulation cotton 12 is used to enhance the insulation effect. Fixing structure 11 is provided at the edge of the left curtain body 10, and fixing structure 21 is provided at the edge of the right curtain body 20.
[0032] Two sets of closed bodies 30 are provided, and the two sets of closed bodies 30 are respectively detachably installed on the side of the fixed structure 11 and the fixed structure 21 that are close to each other.
[0033] In implementation, the left curtain 10 and the right curtain 20 are installed on the door frame respectively. The closing body 30 is detachably installed on the fixed structure 11 and the fixed structure 21. The closing bodies 30 are in contact with each other to close the left curtain 10 and the right curtain 20. People frequently pass through the closing body 30, which can easily cause pollution and stains. When stains appear, the closing body 30 can be removed for targeted cleaning, which is conducive to reuse, saves user costs, and makes the product highly competitive in the market.
[0034] Example 2
[0035] In the above embodiments, such as Figure 2 , Figure 3 As shown, the closed body 30 includes an edge banding strip 31, which is detachably installed on the first fixing structure 11 and the second fixing structure 21. The detachable method is one of snap-fit, adhesive, fastening, or magnetic attraction.
[0036] One implementation method: such as Figure 2As shown, the inner wall of the edge covering strip 31 is provided with two symmetrical and distributed pricking surface structures 32, the two sides of the fixing structure one 11 and the fixing structure two 21 are provided with the rough surface structure 22, and the top, bottom and side of the left curtain body 10 and the right curtain body 20 can also be provided with the rough surface structure 22, so that the installation is convenient, and the edge covering strip 31 is realized by the adhesion of the pricking surface structure 32 and the rough surface structure 22 of the fixing structure one 11 and the fixing structure two 21.
[0037] One embodiment: as Figure 3 As shown, the inner wall of the edge covering strip 31 is provided with a buckle female body 33 and a buckle male body 34 which are matched with each other, and the fixing structure one 11 and the fixing structure two 21 are provided with a through hole and a turned edge metal ring 23 wrapped around the edge of the through hole. The buckle female body 33 and the buckle male body 34 are matched with each other from the two sides of the turned edge metal ring 23 to form a buckling operation.
[0038] Example 3
[0039] In the scheme of example 2, as shown in Figures 1 to 5 As shown, the edge covering strip 31 is provided with a plurality of magnetic blocks 35 which are distributed at equal intervals along the length direction, and the automatic closing operation of the left curtain body 10 and the right curtain body 20 is realized by the adsorption between the magnetic blocks 35.
[0040] Among them, as shown in Figures 2 to 4 As shown, the edge covering strip 31 is provided with a magnetic bag 36 for accommodating the magnetic block 35, the magnetic bag 36 is sewn or ultrasonically welded on the edge covering strip 31 between the two pricking surface structures 32, and the bag opening of the magnetic bag 36 is located at the side. The original magnetic block 35 is wrapped and sewn or ultrasonically welded on the curtain body by the edge cloth, so that the edge cloth near the magnetic block 35 is easy to wrinkle, and the local gap is easy to appear. However, by separately installing the magnetic block 35 on the edge covering strip 31, the problem of wrinkles can be overcome by installing the edge covering strip 31 on the curtain body.
[0041] Example 4
[0042] In the scheme of example 2, as shown in Figure 4 and Figure 5 As shown, the edge covering strip 31 includes an inner layer 311 and an outer layer 312, the two ends of the inner layer 311 and the two ends of the outer layer 312 are integrally connected, and the width of the inner layer 311 is less than the width of the outer layer 312. By the width of the outer layer 312 being greater than the width of the inner layer 311, since the size of the outer layer 312 is greater than the size of the inner layer 311 after the installation of the edge covering strip 31, the outer layer 312 is deformed after the left curtain body 10 and the right curtain body 20 are closed, and the gap is further eliminated.
[0043] Example 5
[0044] In the scheme of example 1, as shown in Figure 1As shown, the top and the side of the left curtain body 10 and the right curtain body 20 are provided with the fixed edge strip 13, which is installed on the door frame.
[0045] As shown in the drawings, the heat preservation door curtain comprises a left curtain body 10 and a right curtain body 20. Figure 1 As shown in the drawings, the heat preservation door curtain comprises a left curtain body 10 and a right curtain body 20. Figure 6 As shown, the heat preservation door curtain further comprises a blocking curtain body 40 installed on the top of the left curtain body 10 and the right curtain body 20, which is used to cover the area that cannot be covered by the top edge strip 31. The blocking curtain body 40 can be installed on the left curtain body 10 and the right curtain body 20 in a magic tape manner, and two sets of blocking curtain bodies 40 can be installed on the left curtain body 10 and the right curtain body 20 respectively on the indoor side and the outdoor side.
[0046] As shown in the drawings, the heat preservation door curtain comprises a left curtain body 10 and a right curtain body 20. Figure 1 As shown, the left curtain body 10 and the right curtain body 20 are provided with detachable and installable perspective windows 50, which are made of PVC. Through the setting of the perspective windows 50, the situation inside and outside the curtain can be observed, the collision during the passing and the unattended indoor room can be avoided to cause the unnecessary entry, and the heat preservation effect is improved.
[0047] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. The replacement can be the replacement of part of the structure, device, method step, or the complete technical solution. According to the technical solution and the utility model concept of the present application, equivalent replacement or change should be covered in the protection scope of the present application.
