retractable storm door

Abstract

The invention relates to a retractable windproof door, which comprises a door frame, a first door body and a second door body. The door frame is composed of a first door post, a second door post, a top beam and a bottom beam and surrounds it to form a door opening. The first The door body includes a plurality of first columns arranged at intervals on the bottom beam. When the door is opened, two adjacent first columns are close to each other and the multiple first columns are all located on the same side of the door opening. When the door is closed, the adjacent two first columns The two first columns are far away from each other and the first columns located at both ends are respectively connected with the first door column and the second door column. The second door body includes a plurality of liftable baffles. The first column is connected, and the baffle plate and the first column are used to block the door opening. In this structure, the opening and closing of the door is realized through the expansion and retraction of the first column, and the baffle is connected with two adjacent first columns, so that the baffle and the first column block the door opening. It has the characteristics of good windproof performance and high wind resistance.

Description

technical field [0001] The invention relates to the technical field of windproof doors, in particular to a telescopic windproof door. Background technique [0002] In the field of windproof door technology, an integral windshield is usually installed on the door frame through a fixing component to block the door opening. The structure of the integral windshield is not conducive to placing the windshield when the door is opened, and requires a large space to store it. For the rolling shutter door, in order to facilitate winding, the thickness of the windshield is small, the strength is weak, and it is easily deformed and damaged when encountering strong winds, which is not conducive to use in the windy environment in coastal areas. Contents of the invention [0003] The object of the present invention is to propose a telescopic method door, which is characterized by good wind resistance and high wind resistance. [0004] For reaching this purpose, the present invention ad...
