The invention relates to a cabinet door leaf locking structure which comprises a cabinet door frame and cabinet door leaves installed in the cabinet door frame. Rotating handle mechanisms and door bolt mechanisms are installed on the cabinet door leaves; the rotating handle mechanisms are arranged in the middles of the side edges of the cabinet door leaves; and the door bolt mechanisms are arranged inside the tops or the bottoms of the cabinet door leaves. The cabinet door leaf locking structure is characterized in that each door bolt mechanism comprises a safety pin rod and a safety pin reset spring; the safety pin reset springs sleeve the safety pin rods and are used for pushing the safety pin rods to move outwards in a reset mode; an upper end part of each safety pin rod is of a slope shape so as to form a lower upper end slope; each upper end slope face the inside of the corresponding cabinet door leaf; the cabinet door frame is provided with safety pin holes for accommodating the upper end parts of the safety pin rods; each rotating handle mechanism comprises a rotating handle installed on the corresponding cabinet door leaf; each rotating handle comprises a handle exposed out of the corresponding cabinet door leaf and a rotating shaft connected with the handle; each rotating shaft penetrates through the corresponding cabinet door leaf; a cleat-shaped shifting piece is installed at the inner side end of each rotating shaft; and the shifting pieces are connected with lower end parts of the safety pin rods through connecting rods.
柜门扇锁闭结构，包括柜门框和安装在柜门框中的柜门扇，柜门扇上安装有旋把机构及门插机构，旋把机构布置在柜门扇侧边的中间位置，门插机构布置在柜门扇的顶部或底部的内侧；其特征在于，门插机构包括插销杆和插销复位弹簧，插销复位弹簧套装在插销杆上用于推动插销杆向外复位移动，插销杆的上端部呈斜坡状从而具有下上端斜面，上端斜面朝向柜门扇的内侧，柜门框上设置有用于接纳插销杆的上端部的插销孔；旋把机构包括安装在柜门扇上的旋柄，旋柄包括外露于柜门扇的把柄和连接把柄的旋转轴，旋转轴穿过柜门扇其内侧端上安装有羊角状的拨片，拨片与插销杆下端部之间通过连接杆连接。
