1. According to the form of opening and closing: it can be divided into sliding door, swing door, overlapping door, folding door, curved door and revolving door. (1) Sliding door: can be subdivided into single open, double open, overlapping single open, overlapping double open and curved door. The curved door leaf smoothly moves along the orphan track and can be divided into a half arc one-way, a half-arc bidirectional, and an all-arc bidirectional. In order to maximize the entrance width, some push-pull (sleeve) automatic doors can be made to open manually after the opening end coincides with the fixed fan, and are also summarized as push-pull automatic doors. (2) Revolving door: It can be subdivided into a central axis type, a round rail hanging type and a center display area. (3) Swing door: It can be subdivided into single unidirectional, double unidirectional, single bidirectional and double bidirectional. (4) Folding door: can be subdivided into 2 folding and 4 folding. (5) Emergency evacuation automatic door: both the movable fan and the fixed fan can be opened at 90 degrees. (6) Overlapping doors: can be divided into overlapping automatic doors with fixed side door pages and overlapping automatic doors without fixed side door pages (7) Curved door: It can be divided into arc segments, semi-circles, full circles, can be fixed with fixed door pages, or can not have fixed door pages. The arc degree can be set according to the specific case design, the application is very flexible, and different arc stitching can also be applied. The structure of the aesthetically versatile geometry is constructed, so the use of Caesar curved doors will become more and more extensive. Application statistics: Push-pull automatic door usage is the largest, accounting for more than 90% of the total of 4 types of automatic doors, followed by rotating automatic doors, accounting for about 6%, and the use of flat-opening and folding automatic doors is the least, each accounting for about 2%. . 2, according to the door material: Stainless steel doors are available in safety glass, stainless steel finishes, architectural aluminum profiles, color coated steel sheets, wood, etc. Other materials are also available. Common types of components are frameless glass automatic doors, stainless steel frame glass automatic doors and aluminum alloy frames (planed or fluorocarbon paint) glass automatic doors. 3, according to the structural characteristics of the door, the automatic door is mainly divided into nine categories, namely automatic revolving door, arc-shaped automatic door, smooth automatic door, swing automatic door, folding automatic door, telescopic automatic door, rolling curtain automatic door , lift automatic door and automatic blocker. 4, according to the purpose of classification, automatic doors are mainly divided into five categories, namely civil automatic doors, commercial automatic doors, industrial automatic doors, garage automatic doors and courtyard automatic doors. The structure and use of the integrated door, the automatic door is mainly divided into the following eight categories.
