Abstract

The invention relates to the technical field of door shafts, in particular to a linked door shaft. The linked door shaft comprises a connecting piece, two fixed blocks and two door shaft bodies; the two door shaft bodies are arranged at the two ends of the connecting piece respectively; the fixed blocks are rotatably connected with the connecting piece through the door shaft bodies; the two fixed blocks refer to the first fixed block and the second fixed block; when the second fixed block rotates around the first fixed block in a first direction, the second fixed block is capable of rotating around the first fixed block in the first direction along the connecting piece; when the connecting piece rotates by a first angle, the second fixed block is capable of rotating around the connecting piece in the first direction. The invention aims at providing the linked door shaft to increase a maximum opening angle of a blank door and solve the technical problem of damage caused by mutual collision of a wall and the blank door in case of seamless connection in the prior art.

Description

technical field [0001] The invention relates to the technical field of door shafts, in particular to a linkage door shaft. Background technique [0002] There are many kinds of decoration styles.
