Description

Technical Field

[0001] The present invention relates to the field of seat installation, in particular to a track seat quick lock structure and a track seat. Background Art

[0002] Ship seats are essential onboard. Depending on the cabin's spatial layout, the needs of different scenarios, individual differences in crew, and other factors, the seats need to be adjusted to different positions and spacings. Currently available adjustment methods often involve bolting to a fixed position, which results in time-consuming and labor-intensive adjustments, a single fixed position, a narrow adjustment range, and significant damage to the cabin floor. There are also some adjustable seat structures, but these rely solely on friction for locking. In the turbulent conditions of the sea, the seat is subject to significant translational impact, and the friction lock can easily fail, leading to accidents. Furthermore, the locking structure is too large, making it easily accessible to non-staff members, which can lead to other unnecessary risks. Summary of the Invention
