Description

High leakproofness push-and-pull door

Technical Field

The invention relates to the field of doors and windows, in particular to a high-sealing sliding door.

Background

Sliding doors are a common door structure, and can be switched between an open state and a closed state by pushing and pulling a movable door leaf left and right, and the door leaf is commonly used in places such as bathrooms, balconies and villas, and the bottom of the sliding door leaves is led to a courtyard. Since the sliding of the door leaves of such sliding doors is limited on the respective tracks, a certain gap is inevitably formed between the door leaves, and the existence of the gap easily causes problems of sealing performance, such as air leakage, water leakage, sound insulation, and the like.

The existing common method is to use a brush or an adhesive tape to isolate the door closing contact edge of the door leaf, when the brush is used, the problems of air leakage and dust entering can be reduced to a certain extent, but the brush is not a sealing element, when severe weather occurs or an air conditioner is arranged in an indoor room, indoor and outdoor air can still circulate through the gap of the brush, and higher sealing requirements cannot be met; use the adhesive tape, when adhesive tape and adhesive tape laminating, the indoor outer circulation of air of separation that can be complete, but when the door leaf frequently slided, there is great frictional force between adhesive tape and the adhesive tape or between adhesive tape and the door body, need apply bigger effort and accomplish the switch door, on the other hand adhesive tape can be rapid damage under the condition of frequent friction. Therefore, the existing mode can not well solve the problem of tightness of the sliding door.
