The invention discloses a dining table locking mechanism for an aviation passenger seat backrest. The dining table locking mechanism comprises a spring bolt, a lock shaft sleeve, a rotating shaft, a lock catch plate, a hook and an elastic piece. The spring bolt is fixed to a seat backrest, a locking hole is formed in the spring bolt, a first limiting protrusion is formed on the lock shaft sleeve and used for being inserted into the locking hole, the rotating shaft is rotationally connected with the lock shaft sleeve, the lock catch plate is fixedly connected with the rotating shaft, the hook is fixedly connected with the rotating shaft, one end of the elastic piece is connected with the lock shaft sleeve, and the other end of the elastic piece is connected with the hook. The dining table locking mechanism provided by the invention has the beneficial effects that the hanging hook is hung on the spring bolt when the device is in a locking state, so that the dining table plate cannot move in the front-back direction, the first limiting bulge is inserted into the locking hole of the spring bolt, so that the dining table plate is locked in the vertical direction and the left-right direction. In this way, the dining table board can be limited in the front-back direction, the left-right direction and the up-down direction through the hooks and the first limiting protrusions, and locking of the dining table board is more reliable.

    本发明公开了一种航空旅客座椅靠背餐桌锁定机构,包括锁舌、锁轴套、转轴、锁扣板、挂钩以及弹性件;锁舌固定于座椅靠背上,锁舌上开设有锁定孔,锁轴套上形成有第一限位凸起,第一限位凸起用于插设于锁定孔内,转轴与锁轴套转动连接,锁扣板与转轴固定连接,挂钩与转轴固定连接,弹性件的一端与锁轴套连接,弹性件的另一端与挂钩连接。本发明提出的技术方案的有益效果是:通过使挂钩在本装置处于锁定状态时挂设在锁舌上,从而使餐桌板无法在前后方向移动,通过将第一限位凸起插设于锁舌的锁定孔内,从而对餐桌板在竖向及左右方向上进行锁定,这样通过挂钩及第一限位凸起可对餐桌板在前后、左右及上下各向进行限位,使餐桌板的锁定更加可靠。
