Description
Technical Field
[0001] The utility model belongs to the technical field of anti-theft doors, and particularly relates to a multifunctional anti-theft door. Background Art
[0002] Anti-theft doors are a type of door product specially designed to improve the security level of residential or commercial buildings. Its main feature is that it has good anti-theft performance. Anti-theft doors are usually made of high-quality steel or stainless steel, with a solid structure and reinforced ribs inside the door body to enhance the ability to resist illegal intrusions such as prying, smashing, and cutting. In order to enhance its anti-theft effect, most of the common anti-theft doors in life are designed to have only anti-theft functions, and cannot provide other functions for users in life, which makes the use of anti-theft doors somewhat inconvenient.
[0003] First of all, most common anti-theft doors are fully enclosed structures, which completely separate the indoor from the outdoor. However, under some conditions, certain ventilation operations are required indoors to refresh the indoor air and improve the comfort of users indoors.
[0004] Secondly, people sometimes need to interact with people outdoors, such as picking up express deliveries or takeout. At this time, the security door needs to be fully opened, which may cause criminals disguised as deliverymen or couriers to cause certain harm to people's safety.
[0005] In summary, there are some problems in the use of single-function anti-theft doors, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
