Technical Field

The invention belongs to the technical field of fixed open doors, and relates to a floor door catch for fixing an outward open safety passage door.

Background

Up to now, especially for doors open outdoors, such as factory workshops, building exit doors, it has been found that these open doors are often held by either a moving stone or brick, or by a stick and fastened by a rope. The device that can fix to outside open door now generally adopts floor spring and door closer, and the floor spring is special for the glass door is supporting to the door limit axle is the impetus, and the dynamics of fixed door is very limited, and wind blows the door and closes automatically. The door closer has technical contradiction, and the function of the door closer is difficult to resist the blowing and scraping of general wind power. The strength is not enough in use, and potential safety hazards exist.

Disclosure of Invention

The invention aims to solve the problems and provides a floor door latch for fixing a door of a safe passage which is open outwards. The door opened to the outside is reliably fixed, and the door opened at will is fixed by the door catch part when blown by wind.

In order to achieve the purpose, the invention adopts the following technical scheme:
