Ventilation device for temporary building

Abstract

The invention provides a ventilation device for a temporary building, and belongs to the technical field of building construction. According to the technical scheme, the ventilation device comprises atop plate arranged at the top end of a house body; a ventilation mechanism is arranged at the middle position of the top plate; a control mechanism is arranged on one side of the ventilation mechanism; the control mechanism drives the ventilation mechanism to be opened or closed; one side of the top plate is hinged with the house body; an ejection mechanism is arranged at the hinged part; and theejection mechanism controls an included angle between the top plate and the house body. The ventilation device has the beneficial effects that the ventilation mechanism can be started or the whole top plate can be opened selectively to exchange air with the outside; the ventilation mechanism in the invention can adjust the size of a ventilation hole by rotating a rotary handle; the control mechanism drives the size of the ventilation hole by a planar connecting rod mechanism; the ejection mechanism in the invention can adjust the included angle between the top plate and the house body, indoorand outdoor air can be can exchanged more fully; and the problems of moisture, mildew and the like caused by frequent generation of fine water in a room are reasonably solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a ventilation device for a temporary building room. Background technique [0002] In temporary construction houses, fine water is often generated indoors, causing problems such as dampness and mildew. In the prior art, the temporary construction houses on the construction site have a limited number of windows, so the indoor air is not easy to circulate, and the indoor environment The temperature is high, and the air exchange with the outside world cannot be performed well. Contents of the invention [0003] The object of the present invention is to provide a ventilation device for a temporary building. [0004] The present invention is achieved through the following measures: a ventilation device for a temporary building, which is characterized in that it includes a top plate arranged on the top of the house body, a ventilation mechanism is set in the middle of t...
