Abstract

The invention discloses an adjustable door spindle which comprises a door spindle seat plate arranged on a door frame or a wall. The adjustable door spindle is characterized in that the door spindle seat plate is provided with a pin shaft, and a door spindle panel connected with a door leaf is hinged to the pin shaft and is turned over along the pin shaft; the adjustable door spindle is furthermore provided with a three-dimensional adjustment mechanism, and the three dimensional adjustment mechanism comprises an up-down adjustment mechanism, a left-right adjustment mechanism and a front-rear adjustment mechanism which are adjusted independently. The adjustable door spindle is compact in structure, flexible in adjustment, high in precision and capable of being adjusted independently in the three-dimensional direction, errors existing in the machining and installation processes are eliminated, the gap between the door leaf and the door frame in the door-closed state is eliminated, good sealing performance is guaranteed, the heat preservation performance and water prevention performance of a door are improved, and grain storage quality is guaranteed.

Description

Technical field [0001] The invention relates to the technical field of door shaft structures, in particular to an adjustable door shaft. Background technique [0002] The closed door for grain storage usually adopts a horizontal opening structure, which can ensure the maximum opening degree of the closed door of the grain storage and facilitate the in and out of grain transportation. On the horizontal opening door, the door leaf is installed on the side of the door with a hinge mechanism, and the door opens inward or outward. The closed door of the grain store needs to have good airtightness when the door leaf is closed, and be able to insulate heat. At present, the door leaf is usually installed on the door frame with a fixed structure of the door shaft. Due to the errors in the processing and installation process, the door leaf is difficult to be installed. When closed, it is kept in a good sealing state with the door frame, which is difficult to keep warm and waterproof, and c...
