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 airtight door used in the grain depot usually adopts a side-hung door structure, which can ensure the maximum opening of the airtight door of the grain depot, and facilitate the entry and exit of grain transportation. On the side-hung door, the door leaf is installed on the side of the door with a hinge mechanism, and the door opens inward or outward. The airtight door of the grain depot needs to have good sealing performance when the door leaf is closed, and can be heat-insulated. 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 process of processing and installation, the door leaf is difficult to open When it is in the closed state, it keeps a good seal with the door frame, so it is difficult to keep warm and waterproof, an...
