Moving component for sliding door of factory building

Abstract

The invention discloses a moving component for a sliding door of a factory building, which is characterized in that: the moving component consists of a supporting assembly (2), two bearings (5) and a bearing strength connecting piece, wherein two ends of the supporting assembly (2) are provided with bearing mounting sections; the two bearings (5) are respectively fixed on the bearing mounting sections of the supporting assembly (2); the bearing strength connecting piece consists of a long bolt (3), an upper nut (4) and a lower nut (6); and the middle part of the supporting assembly (2) is provided with a bolt hole which the long bolt (3) passes through. The moving component adopting the structure is mounted on the sliding door, reduces the push-pull power of a door leaf to make the push and pull convenient as the weight of the door leaf is shared by a beam. Even though a goods vehicle going in and out of the factory building causes slight distortion of a lower rail of the sliding door, the verticality of the door leaf of the sliding door can keep unchanged for a long time to ensure the tight closing of the sliding door.

Description

technical field [0001] The invention relates to a moving part used for a sliding door in a building workshop. Background technique [0002] At present, the structure of the sliding door of the construction workshop includes an upper beam, a lower guide rail and a door leaf. The door leaf is composed of rollers below two or more door bodies that roll along the lower guide rail, the door body and a moving part that moves along the upper beam. The moving part is A guiding structure, the weight of the door is all supported by rollers, and the rollers roll back and forth in the lower guide rail. When the door leaf is opened, trucks and load transport trolleys often pass through the lower guide rail, and the lower guide rail will be slightly deformed, not only pushing and pulling the door leaf. The power of the door is relatively large, and the verticality of the door leaf changes after a period of use, resulting in the door not closing tightly, and the wind and rain can enter the...

Problems solved by technology

[0002] At present, the sliding door structure of the building workshop includes an upper beam, a lower guide rail and a door leaf. The door leaf is composed of more than two rollers below the door body that roll along the lower guide rail, the door body and a moving part that moves along the upper beam. The moving part is A structure that acts as a guide. The weight of the door is all supported by the rollers. The rollers roll back and forth in the lower guide rail. When the door leaf is opened, trucks and load-carrying trolleys often pass by the lower guide rail. The lower guide rail will be slightly deformed, not only pushing and pulling the door leaf The strength of the door leaf is relatively large, and the verticality of the door leaf changes after a period of use, resulting in the door not being closed tightly, and wind and rain can enter the factory building
