Trackless auto-clean high-airtightness sliding door/window

Abstract

The invention discloses a trackless auto-clean high-airtightness sliding door / window, comprising a door / window frame and a door leaf / window sash; tracks on a lower frame member of the door / window frame include front and rear concave flat tracks formed among front, middle and rear vertical frame bars on the flat bottom of the lower frame member; the door leaf / window sash is disposed in the door / window frame correspondingly between the upper and lower frame members, and the door leaf / window sash is slidably moved in the corresponding concave flat tracks of the lower frame member through a multifunctional integrated roller mechanism at the bottom; in the multifunctional integrated roller mechanism, horizontal lateral guide wheels in rolling contact with the lateral sides of the concave flat tracks are arranged in left and right bodies of roller carriers, a rolling wheel in rolling contact with the bottom of the corresponding concave flat track is arranged in the roller carrier between the left and right horizontal lateral guide wheels, and the left and right ends of the roller carrier are provided with plastic sheets or rubber sheets or flexible brushes abutted to the bottoms of the concave flat tracks. The trackless auto-clean high-airtightness sliding door / window can provide effective prevention of separation, has good safety, allows water and dust in the concave flat tracks t be cleaned in time, and is airtight and opaque.

Description

technical field [0001] The invention relates to a sliding door and window, in particular to a trackless automatic cleaning and high airtight sliding door and window. Background technique [0002] Existing common sliding doors and windows, its structure comprises door and window sash (more than two) in the door and window frame, and the bottom of described door and window sash moves left and right by rolling on the single track raised in the lower frame of the door and window by load-bearing rolling wheels. [0003] The problems with ordinary sliding doors and windows are: [0004] 1. Since the doors and windows run on a single track, there is less overlap between the load-bearing rolling wheels and the track, and it is easy to shake when pushing and pulling. When the doors and windows are under the action of external forces (such as positive and negative wind pressure) or obstacles on the track Hazard caused by derailment. [0005] 2. The track protrudes on the lower frame...

AI Technical Summary
