The manual table board comprises a backrest assembly, a table board assembly, connecting rod mechanisms and a locking mechanism, the left side and the right side of the table board assembly are connected with the backrest assembly through the connecting rod mechanisms respectively, and each connecting rod mechanism comprises an upper connecting rod assembly, a lower connecting rod assembly and a table board mounting support. The upper connecting rod assembly and the lower connecting rod assembly are both hinged between the table plate assembly and the table plate mounting support, the table plate mounting support is fixed to the backrest assembly, the backrest assembly is provided with an avoiding hole for the connecting rod mechanism to move, a shielding structure is integrated on the connecting rod mechanism, and after the locking mechanism is unlocked, the table plate assembly turns backwards to drive the connecting rod mechanism to be linked. Therefore, the folding state can be turned to the opening state, and the shielding structure is linked with the folding state and can shield the avoiding hole when the table plate assembly is opened. The table plate assembly is unfolded and folded through movement of the connecting rods, the structure is simple, operation is convenient, the connecting rod mechanism and the shielding structure are integrally designed, and the assembling procedures are effectively reduced.
本发明公开了一种安装在座椅靠背上的手动桌板,包括靠背总成、桌板总成、连杆机构和落锁机构,桌板总成的左右两侧分别通过连杆机构与靠背总成连接,连杆机构包括上连杆总成、下连杆总成和桌板安装支架,上连杆总成和下连杆总成均铰接在桌板总成与桌板安装支架之间,桌板安装支架固定于靠背总成上,靠背总成上设有供连杆机构运动的避让孔,连杆机构上集成有遮蔽结构,当落锁机构解锁后,桌板总成向后翻转能带动连杆机构联动,从而能由折叠状态翻转至打开状态,遮蔽结构随之联动能在桌板总成打开时将避让孔遮挡。本发明通过连杆运动实现桌板总成的打开和折叠,结构简单,操作方便,且连杆机构与遮蔽结构集成设计,有效减少了装配工序。
