Vertical latch locking mechanism for rotating seat

Abstract

Disclosed in the utility model is a vertical latch locking mechanism for a rotating seat, including a vertical latch locking mechanism mounted on a rotating disc in a seat rotation mechanism, at least one lockhole provided on a disc surface of a fixed disc in the seat rotation mechanism, and at least one first lock pin hole provided on the rotating disc. The lockhole is aligned with the first lock pin hole, and the vertical latch locking mechanism includes: a locking pin bracket fixed on the rotating disc; and at least two lock pins vertically and moveably configured on the locking pin bracket. A first end of the lock pin passes through the first lock pin hole and is inserted into the lockhole, to implement locking. In the utility model, a horizontal locking mechanism is changed to a vertical latch mechanism, radial sizes of the rotating disc and the fixed disc are greatly reduced, and a diameter can be reduced to less than 200 mm. In addition, the vertical latch locking mechanism for a rotating seat does not extend beyond the rotating disc and can be hidden at a lower end of a cushion. The lock pin moves in an inner cavity of the rotating disc and does not scratch the outside, providing a good appearance.
