The invention belongs to the technical of elevator ventilation equipment, and particularly relates to a ventilation structure for an elevator ceiling. The ventilation structure comprises an elevator car body, and two through holes are formed in the top inner wall of the elevator car body; an exhaust tube and an air inlet tube are welded in the two through holes fixedly, and cross bars are welded in the exhaust tube and the air inlet tube fixedly; vertical shafts are rotatably installed on the two cross bars, and ventilating fan blades are welded on the tops of the two vertical shafts fixedly;first bevel gears are welded at the bottom ends of the two vertical shafts fixedly, and rotating holes are formed in the inner walls of the sides, close to each other, of the exhaust tube and the airinlet tube; and the same rotating shaft is installed in the two rotating holes rotatably. The ventilation structure is high in practicability, and it can be ensured that ventilation between the elevator and outside is maintained while the elevator works properly; thus, it is ensured that air in the elevator car is fresh, and meanwhile the ventilation structure can facilitate replacement of a filter shield for filtering the air, and is more convenient.
本发明属于电梯通风设备技术领域,尤其为一种电梯顶棚的通风结构,包括电梯轿厢本体,所述电梯轿厢本体的顶部内壁上开设有两个通孔,两个通孔内分别焊接固定有排气管和进气管,所述排气管和进气管内均焊接固定有横杆,两个横杆上均转动安装有竖轴,两个竖轴的顶部均焊接固定有通风扇叶,两个竖轴的底端均焊接固定有第一锥形齿轮,所述排气管和进气管相互靠近的一侧内壁上均开设有转动孔,两个转动孔内转动安装有同一个转轴。本发明实用性高,能够在电梯正常工作的同时使其和外部空气始终保持流通,从而保证电梯厢内部的空气清新,同时还能便于对过滤空气的过滤罩进行更换,较为便捷。
