Sliding door

Abstract

The invention discloses a sliding door which is safe and sanitary in use. The sliding door comprises vertical frames, horizontal frames, a roller assembly and glass. Each vertical frame is provided with a positioning wheel cavity I and a roller cavity I. Each horizontal frame is provided with a positioning wheel cavity II and a roller cavity II. One end of the positioning wheel cavity II is provided with a positioning wheel chute. A positioning wheel is screwed on the ground. When the sliding door is closed in place, the positioning wheel is located in the positioning wheel cavity in two vertical frames or a vertical frame deviated from one side of the centre of the door frame. An opening is arranged on the wall of the positioning wheel cavity I opposite to a chute opening of the positioning wheel chute in connection part of the two vertical frames and the lower horizontal frame. The opening corresponds to the positioning wheel chute in depth and width. An opening is arranged on the outer wall of the roller cavity II in connection part of the two vertical frames and the lower horizontal frame. And the opening on the outer wall of the roller cavity II corresponds to the roller assembly in length and width. The sliding door is always constrained in pushing and pulling process and does not derail. Meanwhile, no obstacles are exposed on the ground, therefore, nobody can be trippedover and no sanitary dead angle can be formed.

Description

technical field [0001] The invention relates to a sliding door, in particular to a sliding door made of profiles. Background technique [0002] With the continuous development of science and technology and social economy, people's living standards are constantly improving, and living conditions are improving day by day. Sliding doors have been popularized and applied in houses. Sliding doors are mainly used as partitions, kitchen doors or other movable doors in residential houses. The structure of the traditional sliding door is as follows: the upper rail is installed on the top of the door frame, and the upper and lower rails are installed on the opposite ground, so that the sliding door as a whole can be pushed and pulled under the constraints of the upper and lower rails. But the traditional sliding door must be provided with lower rails, otherwise the bottom of the sliding door is not restrained, and the sliding door is easy to derail. The light ones will cause the slid...

Problems solved by technology

However, the traditional sliding door must be equipped with a lower rail, otherwise the lower part of the sliding door is not restrained, and the sliding door is easy to derail. The light one will cause the sliding door to not work normally, and the severe one will cause the loss of the sliding door or hurt people.

When the upper and lower rails are installed, obstacles will be added on the ground, which will bring hidden dangers to the activities of the elderly and children; at the same time, dirt is easy to accumulate around the lower rails, which is inconvenient to clean, and it is easy to form a place where dirt is hidden, which is harmful to the living environment. bring adverse effects
