TECHNICAL FIELD

[0001] The utility model relates to a magnetic door curtain, especially a foldable magnetic door curtain. BACKGROUND

[0002] The magnetic door curtain is a functional product used for heat insulation, dust prevention, mosquito prevention and the like on a room door in China.

[0003] Usually, the door curtain is rolled up or folded for storage when seasons change, and is used again the next year, but when the door curtain is used again the next year, the plastic magnetic strip is stiff and curled and cannot be unfolded straight, so that the door curtains cannot be well attracted to each other, there are folds, and holes are formed between the door curtains, so that mosquitoes can easily enter the room, and the door curtain loses the protective effect and is discarded.

[0004] Every year, a certain number of door curtains are discarded by the whole society, and the discarded door curtains pollute the environment and waste production resources, causing unnecessary waste to consumers.

[0005] Therefore, it is a meaningful work to design and manufacture a foldable and reusable magnetic door curtain.

[0006] According to research and summary, the reason why the magnetic door curtain is not convenient to fold is the problem of the plastic magnetic strip. In actual use, the magnetic door curtain and the plastic magnetic strip have the following defects: 1. It is not convenient to fold and store, and cannot be folded flat; it cannot be stacked into shape; it cannot be restored to a straight line by artificial force, and the attraction does not match, there are folding angle gaps, bending and irregularity, and it is easy to break when folded hard. 2. The door curtain and the plastic magnetic strip stored after being rolled hard and folded hard are easy to be hardened and cannot be restored to be straight; when reused, they cannot be hung and placed vertically into a straight line, so that the corresponding door curtains cannot be naturally attracted, a large gap is formed, the function and performance of the natural connection and closure of the door curtains are lost, the connection, closure and sealing functions of the door curtain with the plastic magnetic strip are lost, and the door curtain is discarded. 3. The discarded door curtain and the plastic magnetic strip pollute the environment and waste production resources, cause unnecessary waste to consumers, and make the production enterprises have high cost and low benefit. 4. In addition, because the magnetic attraction between the plastic magnetic strips is large, the force required to open the door curtain is large, the door curtain is damaged, and the service life of the door curtain is affected.

[0080] described Figure 3 In the invention, the plastic magnetic strip (1) and the plastic magnetic strip (1) are attracted together under the action of magnetic attraction, and the plastic magnetic strip (1) has N plastic magnetic blocks (111), N grooves (112), and N plastic magnetic ribs (111T); the plastic magnetic blocks (111) and the plastic magnetic ribs (111T) are spaced and distributed on the adhesive tape (12) of the plastic magnetic strip (1); due to the action of the grooves (112) on both sides of the plastic magnetic ribs (111T), the plastic magnetic strip (1) has a flexible property of being able to bend and straighten freely, so that when the two plastic magnetic strips (1) are used in parallel, the mutual magnetic attraction force is good, and each of them can be bent freely, so that they can be attracted and attached tightly when bent and parallel to each other, and can be easily separated and combined, which is very suitable for the needs of flexible attraction connection between door curtains.
