Description

Technical Field

[0001] The utility model belongs to the field of anti-theft door equipment, in particular to a mother-and-child type anti-theft door. Background Art

[0002] The mother-and-child security door is a special type of security door, which consists of two door leaves, one large and one small. The large door leaf is called the mother door, and the small door leaf is called the child door. In actual use, the mother-and-child security door has the problem of not having a bottom hole component, which may limit the practicality of the door. For example, in some cases, when it is necessary to pass items or perform some specific operations through the door hole, it will be restricted. Furthermore, this may affect the overall design and aesthetics of the door. This is because the lack of a bottom hole component will not only lead to the above problems, but also the lack of a bottom hole component. The appearance of the door may appear more traditional and single, and cannot meet the needs of some users for personalization and fashion. Therefore, it is necessary to propose a new structure to solve the above technical problems. Utility Model Content
