Problems solved by technology

[0002] There are many types of sliding doors, and the ordinary sliding doors with simple structure are poor in moisture resistance, heat insulation and sound insulation, and wind, rain, snow, dust, etc. are easy to enter the doors and windows , so it is easy to be damaged by corrosion, etc., which affects the service life, the drainage capacity is not enough, and the conflict with the structure is greater. Poor, and in order to increase the above physical properties, many new doors and windows with complex and thick structures appear. This type of doors and windows is expensive, installation and maintenance are very inconvenient, and the performance improvement rate is not high

Abstract

The invention relates to the technical field of doors and windows, in particular to a four-leaf sliding door, which comprises a main door frame. The main door frame comprises an upper rail, a lower rail and side jambs; a pair of sliding door leaves and a pair of fixed door leaves are arranged in the main door frame; the lower rail comprises an inner bottom support portion, a buffer connecting bearing portion, a middle bottom support portion and an outer protective strengthened support portion which are orderly integrally connected; a guide rail is arranged on the inner bottom support portion; the upper rail comprises an inner top limit portion, an upper transitional connecting portion, a middle top limit portion and an upper outer protective strengthened limit portion which are orderly integrally connected; a pair of sliding screen doors which can slide in the left-right direction are arranged between the upper outer protective strengthened limit portion and the outer protective strengthened support portion; another guide rail which extends along the left-right direction is arranged on the upper portion of the outer protective strengthened support portion; and a strengthened limit post is arranged on the upper outer protective strengthened limit portion. The four-leaf sliding door is simple and firm in structure, low in cost, long in service life, excellent in sealing performance, excellent in waterproof performance and also high in wind load resistance.

Description

technical field [0001] The invention relates to the technical field of doors and windows, in particular to a four-leaf sliding door. Background technique [0002] There are many kinds of existing sliding doors, and ordinary sliding doors with simple structures have poor moisture-proof, heat-insulating, and sound-insulating capabilities. Insufficient, the conflict with the structure is greater, in addition, the strength of the structure is not high, and it is not conducive to use in high-rise buildings, because its physical properties such as wind pressure resistance are poor, and in order to increase the above physical properties, many new structures are complex Thick doors and windows appear, but the cost of such doors and windows is high, installation and maintenance are very inconvenient, and the performance improvement rate is not high. Contents of the invention [0003] An object of the present invention is to provide a four-leaf sliding door with simple and firm str...
