Description

High-airtightness barrier-free corner sliding door

Technical Field

The utility model relates to a high-airtightness barrier-free corner sliding door.

Background

The utility model aims at narrower spaces in buildings, such as entrance hallways, corridor passageways, toilets, guest sleeping areas and the like, and common use scenes are mostly common side-hung doors or sliding doors, wherein the sliding doors can be further subdivided into embedded sliding doors, suspended sliding doors and the like.

Taking the vertical hinged door as an example, most vertical hinged doors can realize sealing only by installing a door pocket in a door opening, but the door pocket undoubtedly reduces the width of the door opening, so that the access space is more tense. When the vertical hinged door is completely closed, a door seam is formed at the bottom, so that the heat insulation, noise elimination and sound insulation as well as dust prevention and insect prevention in a room are all adversely affected. In order to solve the problem, a threshold can be selectively installed or a lifting sealing strip, a door bottom sealing baffle and other members are embedded at the bottom of a door plate, however, the height of the threshold can influence the in-and-out use of a user, especially the in-and-out use of tools such as wheelchairs of special groups; the lifting type sealing strip is easy to wear and age in long-term use and cannot be completely attached to the ground, so that a gap is formed; although the door bottom sealing baffle can completely fit the ground, the door plate can rub against the floor to generate noise and adhere dust and debris when moving, and the glued part is easy to damage and then fall off in long-term friction.

Although the vertical hinged door is easier to install and use compared with a sliding door, a certain space is required when the door leaf is opened, and the inward-pushing door cannot be selected for a room with a small size or crowded furniture, otherwise, the entrance and exit of a user are influenced.

Compared with a vertical hinged door, the sliding door has higher space adaptability, and can be opened or moved randomly according to use scenes, structural forms and the like, so that the space is changed in a split-combination mode, and the door moves randomly. In modern life, indoor spaces such as bedrooms and bathrooms are not necessarily fixed four-side walls, for example, a dry-wet separation bathroom surrounded by glass, so that the sliding door is suitable for separating the spaces.

From the classification of door opening methods, sliding doors can be classified into three major categories, namely an externally-attached type, an embedded type and a folding type: firstly, the outer formula push-and-pull door of pasting is installed outside the entrance to a cave, and upper or lower both ends slide rail is obviously adorned, and not only the installation simple process is convenient, also the easy access change, and although less to the wall body interference, but need occupy the partial area of side wall. Secondly, embedded sliding door hides structures such as slide rail, pulley, with during the door plant embedding door opening, secretly adorns the push-and-pull door still can install the door leaf in the side wall, and bigger degree saves space, but need carry out great degree's destruction to the side wall, also is difficult for the maintenance when the slide rail breaks down and blocks the door plant. Third, foldable push-and-pull door generally forms by the combination of many door plants, is fit for as nimble indoor wall, both can realize the space utilization maximize, also can reduce the space that the push-and-pull needs through folding door leaf as far as possible, but gives sound insulation, waterproof performance is not good, and the hardware is also fragile.

The three-analogy sliding door has thousands of autumn in use, but has slight defects under the dual requirements of sealing and convenience: the bottom of the sliding door with the rail on is provided with no doorsill, so that a user can conveniently come in and go out, but the effects of noise elimination, sound insulation, dust prevention and insect prevention are poor; the sliding door with the track at the bottom has good sealing performance, but is not beneficial to the user to come in and go out, and particularly, the service life of the track is shortened by long-term treading of tools such as wheelchairs of special groups, and the sealing effect is influenced.

Based on present building space polytropy, and the current situation that push-and-pull door sealing performance is not enough, the result of use needs to promote, engineering technical personnel need one kind both can satisfy the door leaf and seal, can guarantee the push-and-pull door structure of accessible again.
