Description

Technical Field

[0001] The utility model belongs to the technical field of anti-theft doors, and particularly relates to a double-door three-color anti-theft door. Background Art

[0002] Anti-theft door, also known as anti-theft safety door, is an entrance door with anti-theft function, mainly used in homes, offices and other places that require security, it can meet people's needs for anti-theft function. Most common anti-theft doors have a single-door structure. When criminals want to enter the room by prying open the anti-theft door or unlocking it, they only need to open a single door to enter, so there may be some deficiencies in the anti-theft function.

[0003] First of all, the time it takes for criminals to open the single-door security door is different, and the anti-theft performance of the inner security door is often greater than that of the outer security door. Criminals often need twice the time to open the security door of a single-door structure. This causes criminals to become nervous due to the continuation of time during the door opening process, and thus cannot open the inner security door, thereby improving the anti-theft effect.

[0004] Secondly, the inner security door of the double-sided security door is partially blocked by the outer security door. Criminals cannot quickly identify the door opening method through simple visual inspection, and often need to observe closely to make a judgment. This creates uncertainty for criminals and prevents their subsequent illegal activities.

[0005] In addition, the common single-door anti-theft door is not equipped with an indoor anti-theft structure. When the user is indoors, if the lawless elements open the door, it may cause certain harm to the personal safety of the user.

[0006] In summary, the anti-theft door with a single door structure has certain deficiencies in anti-theft performance, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
