Railless sliding door

Abstract

The invention relates to a railless sliding door. The door comprises a door body, a hollow bottom beam and a support roller component, wherein the support roller component comprises a bracket and an upper roller and a lower roller which are arranged on the bracket in a rotating mode; the upper roller and the lower roller are accommodated in the bottom beam; an upper working surface and a lower working surface are arranged in the bottom beam; the outer circumferential surface of the upper roller is in rolling friction contact with the upper working surface; the outer circumferential surface of the lower roller is in rolling friction contact with the lower working surface; the upper working surface comprises an upper horizontal surface positioned on the middle part, an upper left inclined surface positioned at the left end and an upper right inclined surface positioned at the right end; the lower working surface comprises a lower horizontal surface positioned on the middle part, a lower left inclined surface positioned at the left end and a lower right inclined surface positioned at the right end; the upper left inclined surface and the lower right inclined surface are gradually inclined leftwards from top to bottom; and the upper right inclined surface and the lower left inclined surface are gradually inclined rightwards from top to bottom. The parallelism of the upper working surface and the lower working surface of the railless sliding door can be ensured, and the stable operation of the door body is ensured.

Description

technical field [0001] The invention relates to a trackless translational door. Background technique [0002] The door is an important part of the perimeter of the building. Common doors include telescopic doors, tracked sliding doors, trackless sliding doors, and double-leaf swing doors to realize the closing and opening of the enclosure, so as to achieve the purpose of enclosure security control. Due to the needs of aesthetics and coordination, trackless sliding doors have gradually replaced traditional sliding doors and are more and more widely used. The traditional sliding door is based on pre-embedded rails, which requires complicated nodes in the foundation construction process and high installation accuracy requirements, and the existence of the rails has a considerable impact on vehicles entering and exiting. The long-term heavy pressure will damage the joints of the entrance and exit rails, resulting in failure. use. The trackless sliding door does not install dev...
