The marine extension ladder comprises a plurality of step ladder units which are sleeved step by step, each step ladder unit comprises a supporting platform, a pedal and a limiting unit, an opening is formed in the side face of each supporting platform, a containing cavity is formed in each supporting platform, and each opening communicates with the corresponding containing cavity; the next step ladder unit is arranged in the opening of the supporting platform of the previous step ladder unit in a sliding mode, a containing groove is formed in the surface of the supporting platform adjacent to the side where the opening is located, a plurality of pedals are arranged in the containing groove in the opening direction at intervals in an array mode, and the pedals are rotationally connected with the supporting platform. A rotating shaft of the pedal is parallel to the surface of the supporting platform on the side where the containing groove is located and perpendicular to the opening direction, a connecting rod is perpendicularly arranged on the rotating shaft of the pedal, the connecting rod and the containing groove are connected through a limiting unit, and the limiting unit can selectively fix the angle between the connecting rod and the bottom face of the containing groove. The marine extension ladder disclosed by the invention is more reasonable in structural design, can realize the function of a step ladder channel, and can also be used as a slide way.

    本发明提出了一种船用伸缩梯,包括:多个逐级套合的步梯单元,步梯单元包括支撑平台、踏板和限位单元,支撑平台的侧面设有开口,支撑平台内部设有容纳腔,开口与容纳腔连通,下一级步梯单元滑动设置在上一级步梯单元的支撑平台的开口内,与开口所在一侧相邻的支撑平台的表面设有容纳槽,容纳槽内沿开口方向间隔阵列设有多个踏板,踏板与支撑平台转动连接,踏板的转轴与容纳槽所在一侧的支撑平台表面平行且与开口方向垂直,踏板的转轴上垂直设置有连接杆,连接杆与容纳槽之间通过限位单元连接,限位单元可对连接杆相对容纳槽底面之间的角度进行选择性固定。本发明的船用伸缩梯,结构设计更加合理,可以实现步梯通道作用,还可以作为滑道。
