Description

Anti-theft door capable of forced ventilation

Technical Field

The utility model relates to a burglary-resisting door, specific saying so relates to a burglary-resisting door that can forced draft, and it is used when the not good small family type resident family of ventilation condition needs forced draft to take a breath in the mainly used high-rise apartment.

Background

The security door has become a standard in cities in China, and in recent years, almost all new sold houses are provided with the security door. At present, the security door can be roughly divided into two types in terms of structure, one is a single-layer security door, and the other is a double-layer security door. The outer layer door of the double-layer anti-theft door is a screen door capable of ventilating, the outer layer screen door only has light anti-theft capacity, the inner layer door is a thick and heavy iron door and plays a main anti-theft role, and when the indoor needs to ventilate, the inner layer iron door only needs to be opened; the single-layer anti-theft door only has one layer of thick and heavy iron door. However, for small-sized residents in high-rise apartment buildings, because the whole room is not transparent, most of the small-sized residents only have windows in one direction, and many of the small-sized residents have no windows even in toilets, so that the selection of proper security doors to ensure indoor ventilation becomes a big thing.

If a single-layer anti-theft door is adopted by small-family residents in a high-rise apartment building, when ventilation is needed indoors, a gate is required to be opened to face a corridor, so that privacy is easily exposed and safety is not ensured; if the double-layer anti-theft door is adopted, the ventilation is seemingly realized and the safety is higher, but in reality, the corridor of the apartment building is not greatly ventilated, so the ventilation effect after the double-layer anti-theft door is adopted is also limited. In addition, because the distances between the gates and the gates of the small-dwelling houses in the high-rise apartment building are relatively short, if the double-layer anti-theft doors are used, the situation that the gates collide with the gates happens occasionally, the small-dwelling houses in the high-rise apartment building are usually provided with single-layer anti-theft doors, and therefore, inconvenience is brought to the lives of the small-dwelling houses.

Disclosure of Invention

An object of the utility model is to overcome prior art's not enough, provide a burglary-resisting door that can forced draft, it utilizes the exhaust fan of installing on the burglary-resisting door to carry out forced draft to take a breath indoor, because the gate is closed this moment, so can not expose individual privacy yet.

In order to achieve the above purpose, the utility model discloses a method is: a burglary-resisting door capable of forced ventilation comprises a main door, a small door and an exhaust fan, wherein the main door is a composite door body consisting of a frame, a surface steel plate and an internal filler, a small door frame is arranged at the lower part of the main door, the small door is hinged in the small door frame and also consists of the frame, the surface steel plate and the internal filler, a fine steel screen window is arranged outside the small door frame, when the small door is opened, the fine steel screen window can play a daily natural micro ventilation role, a round hole is arranged at the upper part of the main door, the exhaust fan is arranged in the round hole and plays a role in forced air exhaust and ventilation, an air door is hinged to the inner side surface of the round hole of the main door, the air door is closed at ordinary times, and when forced ventilation is needed, the air door is opened and the exhaust fan is started.

The utility model has the advantages that: on the basis of the original single-layer anti-theft door, the exhaust fan arranged on the anti-theft door is used for carrying out forced ventilation on the indoor space under the condition of closing the door, so that the problem of ventilation can be rapidly solved without exposing individual privacy, and the small door at the lower part of the door can play a role in micro ventilation at ordinary times.
