[0033] Please refer to Figures 1 to 3 , now the plastic heat insulation curtain piece provided by the utility model will be described. The plastic heat insulation curtain piece comprises a curtain piece main body 10 and magnetic attraction strips 30 arranged on both sides of the curtain piece main body 10, the curtain piece main body 10 comprises two flexible outer pieces 11 and a supporting framework 20, and the two flexible outer pieces 11 are arranged at intervals; the supporting framework 20 is arranged between the two flexible outer pieces 11 and connected with the two flexible outer pieces 11, and the rigidity of the supporting framework 20 is greater than that of the flexible outer piece 11.
[0034] By arranging the supporting framework 20 between the flexible outer pieces 11, a hollow structure, i.e. an air chamber, is formed, on the one hand, under the curtain piece with the same thickness, the amount of required material is reduced, and the material is effectively saved; on the other hand, the stiffness and the heat preservation and insulation effect of the curtain piece can be effectively improved.
[0035] The plastic heat insulation curtain piece has the advantages that, compared with the prior art, the plastic heat insulation curtain piece has a three-layer structure, is composed of two flexible outer pieces 11 and a supporting framework 20 in the middle, the supporting framework 20 can provide good stiffness, and a plurality of air chambers are formed between the supporting framework 20 and the two flexible outer pieces 11, so that the heat preservation and insulation effect of the curtain piece is effectively improved.
[0036] In one specific embodiment of the plastic heat insulation curtain piece provided in the embodiment of the utility model, the flexible outer piece 11 is bonded, hot-melt connected or integrally formed with the supporting framework 20.
[0037] It should be noted that the bonding is bonding by using glue; the hot-melt connection is hot-melt compounding the flexible outer piece 11 and the supporting framework 20 together by using a hot-melt device; and the integrally forming is directly generating the curtain piece containing the flexible outer piece 11 and the supporting framework 20 by using an integrally forming device.
[0038] As shown in Figure 2 and Figure 3 , in one specific embodiment of the plastic heat insulation curtain piece provided in the embodiment of the utility model, the supporting framework 20 has a wave shape structure or a corrugated structure, so that the supporting framework 20 can provide sufficient support effect with thinner material.
[0039] As shown in Figure 2 and Figure 3 , in one specific embodiment of the plastic heat insulation curtain piece provided in the embodiment of the utility model, the wave shape structure of the supporting framework 20 extends along the width or length direction of the flexible outer piece 11.
[0040] It should be noted that when the wave shape structure of the supporting framework 20 extends along the width direction of the flexible outer piece 11, the curtain piece is easy to roll and store; and when the wave shape structure of the supporting framework 20 extends along the length direction of the flexible outer piece 11, the curtain piece is more difficult to curl.
[0041] Preferably, the wave shape structure of the supporting framework 20 extends along the length direction of the flexible outer piece 11.
[0042] As shown in Figure 2 and Figure 3 , in one specific embodiment of the plastic heat insulation curtain piece provided in the embodiment of the utility model, the wave shape of the wave shape structure of the supporting framework 20 is a sawtooth wave, a sine wave, a square wave or a trapezoidal wave.
[0043] It should be noted that the sine wave mentioned here is a sine wave structure, which means that the wave shape is arc-shaped.
[0044] Specifically, the wave crest and the wave trough of the supporting framework 20 are connected with the two flexible outer pieces 11 respectively, and the connection mode is glue bonding or hot-melt connection.
[0045] As Figure 2 and Figure 3 shown, in a specific embodiment of the plastic heat insulation curtain sheet provided by the embodiment of the utility model, the flexible outer sheet 11 and the supporting framework 20 are light-transmitting materials.
[0046] Specifically, it can be a transparent material, a colored light-transmitting material, a frosted material, or other materials with certain light-transmitting properties to ensure lighting.
[0047] As Figure 2 and Figure 3 shown, in a specific embodiment of the plastic heat insulation curtain sheet provided by the embodiment of the utility model, the flexible outer sheet 11 and the supporting framework 20 are transparent materials.
[0048] Specifically, as Figure 2 and Figure 3 shown, in a specific embodiment of the plastic heat insulation curtain sheet provided by the embodiment of the utility model, the material of the flexible outer sheet 11 is PVC, TPU, TPR, or TPE, and the material of the supporting framework 20 is PVC, PC, PET, or TPU.
[0049] It should be noted that PVC, TPU, TPR, and TPE all have good wear resistance, light-transmitting properties, and flexibility, and are used to make the flexible outer sheet 11 to ensure the wear resistance, light-transmitting properties, and flexibility of the curtain sheet; meanwhile, PVC, PC, PET, and TPU can have good supporting rigidity and light-transmitting properties, and are used to make the supporting framework 20 to ensure the stiffness and light-transmitting properties of the curtain sheet.
[0050] It should be noted that the flexible outer sheet 11 and the supporting framework 20 are two different materials or the same material, and if they are the same material, two different types of the same material need to be selected to ensure that the supporting framework 20 has sufficient supporting rigidity and the curtain sheet has good stiffness.
[0051] As Figure 2 and Figure 3 shown, in a specific embodiment of the plastic heat insulation curtain sheet provided by the embodiment of the utility model, the thickness of the supporting framework 20 is 1-2 mm, and the thickness of the flexible outer sheet 11 is 0.3-1 mm.
[0052] In a specific embodiment, the thickness of the supporting framework 20 is 2 mm, the thickness of the flexible outer sheet 11 is 0.5 mm, and the total thickness of the curtain sheet is 3 mm.
[0053] As Figure 1 and Figure 2As shown, in a specific embodiment of the plastic heat insulation curtain piece provided by the embodiment of the utility model, two magnetic strips 30 are further included, which are respectively arranged on the two sides of the curtain piece main body 10 and connected with the flexible outer piece 11 to form a magnetic curtain piece, and a plurality of pieces are arranged side by side to form a magnetic door curtain.
[0054] Specifically, the magnetic strip 30 adopts the component on the existing magnetic door curtain, and is connected with the curtain piece main body 10 in a hot melting or glue bonding mode.
[0055] Based on the same inventive concept, the embodiment of the utility model provides a plastic magnetic door curtain, which comprises a plurality of plastic heat insulation curtain pieces.
[0056] The plastic magnetic door curtain provided by the utility model has the advantages that, compared with the prior art, the plastic magnetic door curtain provided by the utility model adopts the plastic heat insulation curtain piece, and therefore has good stiffness and heat preservation and insulation effects.
[0057] The above is only a preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
