Building body ventilating device

Abstract

The invention discloses a building body ventilating device. The building body ventilating device comprises a transparent plate installed at the position of a ventilating opening, a through ventilating cavity is formed in the middle of the transparent plate, the outer side end of the ventilating cavity is sealed through a movable plate, the outer side ends of the upper and lower ends of the transparent plate are each provided with a fixing plate, the opposite faces of the fixing plates are each provided with a sliding groove, a sliding block is installed in each sliding groove, a spring is installed in each sliding groove, each sliding block is installed in the corresponding sliding groove and is in contact with the end face of one side of the corresponding spring, the upper and lower ends of the movable plate is each provided with a rotating shaft, the rotating shafts are arranged at the middle portions of the upper and lower end faces of the movable plate, and the opposite faces of the sliding blocks are each provided with a rotating shaft hole. The building body ventilating device is simple in structure, the movable plates can be conveniently pushed outwards, the ventilating cavity is opened, and air inlet is achieved; and an air guide structure can be formed by rotating the movable plate, external airflow is guided to enter an indoor place, more space is saved by the ventilating manner in the aspect of opening manner, external space is reasonably used, space of a building body is not used, and opening is more convenient.

Description

technical field [0001] The invention relates to a ventilation device, in particular to a building ventilation device. Background technique [0002] The general building ventilation structure adopts the structure of windows. There are many types of windows, such as push-open windows or movable windows, but the structure of push-open windows is prone to breakage and damage in windy weather, and is very easy to damage. Therefore, the aluminum alloy sliding window is the most used at present. It generally has two sides of glass when in use. Pushing one side of the glass to make the two sides of the glass overlap each other can open the window, but this method has a disadvantage, that is, the original With a volume as large as a window, only half of it can let in the wind, wasting the space of the other half.

[0002] The general building ventilation structure adopts the structure of windows. There are many types of windows, such as push-open windows or movable windows, but the structure of push-open windows is prone to breakage and damage in windy weather, and is very easy to damage

Therefore, the aluminum alloy sliding window is the most used at present. It generally has two sides of glass when in use. Pushing one side of the glass to make the two sides of the glass overlap each other can open the window, but this method has a disadvantage, that is, the original With a volume as large as a window, only half of it can let in the wind, wasting the space of the other half

Furthermore, it is difficult for external airflow to enter the room. It can only enter when the airflow is directly facing or obliquely facing the window, and there is no wind guiding effect.
