Problems solved by technology
[0002] The thermal insulation door curtain is a kind of equipment that can isolate the outdoor temperature. Most of them are used in the cold winter to isolate the outdoor cold air and ensure the warmth of the room. It is widely used in supermarkets and other places. When it is pushed away and resets, it will produce a large impact force, so it is easy to cause injury to the latecomers, so a device is needed to solve such situations
