The invention discloses a cylindrical marine liftable sail mast, which is characterized by comprising an outer mast (100) and an inner mast (200), and the inner mast (200) is slidably sleeved in the outer mast (100); the outer-layer mast (100) comprises an outer-layer mast pipe wall (121) and an outer-layer mast outer slideway (120); the inner-layer mast (200) comprises an inner-layer mast pipe wall (231) and an inner-layer mast inner slideway (230); the outer-layer mast (100) is matched with the trapezoidal section structure on the inner-layer mast (200) through the trapezoidal section clamping groove structure to form a locking type slide way structure. The cylinder type marine liftable sail mast is simple in slide way structure, easy to produce, manufacture and assemble, high in production efficiency, low in stress at the end part of the mast, safe and reliable, and capable of avoiding the situation that the mast is stuck when the inner-layer mast and the outer-layer mast slide relative to each other.

    本发明公开了一种圆筒式船用可升降式风帆桅杆,其特征在于,包括:外层桅杆(100)、内层桅杆(200),内层桅杆(200)可滑动地套在外层桅杆(100)内;所述外层桅杆(100)包括:外层桅杆管壁(121)、外层桅杆外滑道(120);所述内层桅杆(200)包括:内层桅杆管壁(231)、内层桅杆内滑道(230);外层桅杆(100)通过梯形剖面卡槽结构与内层桅杆(200)上梯形剖面结构相配合,构成锁紧式滑道结构。一种圆筒式船用可升降式风帆桅杆,滑道结构简单,生产制造装配容易,生产效率高,桅杆端部应力低,桅杆的安全可靠,内外层桅杆相互滑动时避免了卡死的情况发生。
