Technical Field

[0001] This invention relates to the field of elevator equipment technology, and in particular to an elevator traction fixing device. Background Technology

[0002] A home elevator is an elevator installed in a private residence for the exclusive use of a single family member. Due to height restrictions in private residences, home elevators typically employ a machine-room-less design.

[0003] In existing traction machine-room-less elevators, the traction steel belt is fixedly connected at both ends using rope end bars and rope end springs. Although this method allows for tension adjustment of the traction steel belt at both ends via rope end springs, the relatively long length of the rope end bars and springs occupies a certain amount of vertical space in the elevator shaft, reducing the utilization rate of the top floor space. This necessitates increasing the length of the elevator shaft during installation, increasing installation difficulty, and impacting installation efficiency. Summary of the Invention
