Description

Technical Field

[0001] The utility model relates to the technical field of anti-theft doors, in particular to a composite multifunctional anti-theft door. Background Art

[0002] As a specially designed security feature, the core function of a security door is to protect residents by resisting unauthorized opening attempts, such as picking or breaking the lock, for a specified period of time. These doors are equipped with high-level security locks to effectively prevent unauthorized entry. Security doors are categorized by security level, with each level corresponding to a different resistance to unauthorized opening, thus meeting the security needs of different users.

[0003] However, a significant drawback of existing security door designs is the lack of effective ventilation. While this design enhances the door's security, it neglects maintaining indoor air quality. When improving air quality is needed, users often leave doors and windows open for extended periods, which not only disrupts the indoor temperature balance but can also lead to significant energy loss. For example, in hot summers or cold winters, leaving doors and windows open for extended periods causes rapid loss of both warm and cool air, increasing the operating costs of air conditioning or heating systems and placing an unnecessary burden on the environment. Furthermore, security doors lacking ventilation are inconvenient for receiving express deliveries, takeout meals, or other items. Each time an item is received, the user must fully open the door, which not only increases the complexity and time required, but also potentially exposes personal privacy. When opening the door to retrieve an item, people outside the door can directly see into the room, increasing potential safety hazards. This design can be particularly disturbing at night or for people living alone. Currently, no effective solution has been proposed to address these issues in the related art. Utility Model Content
