A door curtain

Abstract

The invention provides a door curtain comprising a door curtain body. The inner side edges of the door curtain body are provided with a plurality of magnetic members; the door curtain body is divided into two parts and every two magnetic members arranged at the corresponding positions of the different parts have different polarities. The door curtain is characterized in that a memory metal strip is arranged between every two magnetic members arranged on the same part; the magnetic members at least include two balance weight magnets arranged at the lower corner points of the inner side of the door curtain body separately; the door curtain also comprises a mating member; when the door curtain body is in an opened state, the mating member provides opposite restoring force for the balance weight magnets; when the door curtain body is fully opened, first reset force is provided via the memory metal; when the door curtain body is nearly closed, the magnetic blocks provide second reset force, so that the door curtain body is fully closed; when the first reset force is reduced, the second reset force is increased, so that the service life is prolonged; during opening, the initial deformation restoring force of the memory metal is small and the magnetic attraction force is large, so that the door curtain is not extremely difficult to open.

Description

technical field [0001] The invention relates to a door curtain. Background technique [0002] The door curtains on the existing market are basically installed on the top of the door frame beam. This kind of door curtain installation structure needs to open the door curtain on one side, so that on the one hand, you need to free your hand to open the door curtain. Fly into the interior while opening. Therefore, the patent with the notification number CN104026955A discloses a magnetic suction type automatic closing door curtain and its installation method. Through the setting of this door curtain structure, since the inner sides of the two door curtain bodies are closely attached when closed and the magnetic poles are arranged at longitudinal intervals Magnets with opposite directions, so after people pass by, the magnets on the inner side of the two curtains will automatically attract together to close the curtains. Therefore, the magnetic suction type automatic closing door...

AI Technical Summary

Problems solved by technology

[0003] However, there are major shortcomings. Since the material of the door curtain is a flexible material, after opening, if it is used for a long time, the deformation will be difficult to reset (due to the large opening and closing angle and the material of the door curtain body is very prone to deformation fatigue. )
