Rolling connection mechanism of three-section type carbon fiber fire-fighting extension ladder
A rolling connecting mechanism of a three-section type carbon fiber fire-fighting extension ladder comprises a lower connecting assembly and an upper connecting assembly. The lower connecting assembly comprises a lower guide limiting assembly and a first middle guide assembly; the lower guide limiting assembly comprises a first upper limiting rolling mechanism, a first side limiting rolling mechanism and a first lower limiting rolling mechanism; the first middle guide assembly comprises a second upper limiting rolling mechanism and a second side limiting rolling mechanism; the upper connecting assembly comprises an upper guide limiting assembly and a second middle guide assembly; the upper guide limiting assembly comprises a third upper limiting rolling mechanism, a third side limiting rolling mechanism and a third lower limiting rolling mechanism; the second middle guide assembly comprises a fourth upper limiting rolling mechanism and a fourth side limiting rolling mechanism; the fire-fighting extension ladder is fixed through the lower guide limiting assembly and the upper guide limiting assembly, so that the fire-fighting extension ladder is stable and safe, meanwhile, the first middle guide assembly and the second middle guide assembly are additionally arranged for rolling, stretching and retracting are convenient during use, manual operation is reduced, and the service life is prolonged.
一种三节式碳纤维消防拉梯的滚动连接机构，包括下连接组件和上连接组件；下连接组件包括下导向限位总成和第一中间导向总成；下导向限位总成包括第一上限位滚动机构、第一侧限位滚动机构和第一下限位滚动机构；第一中间导向总成包括第二上限位滚动机构、第二侧限位滚动机构；上连接组件包括上导向限位总成和第二中间导向总成；上导向限位总成包括第三上限位滚动机构、第三侧限位滚动机构和第三下限位滚动机构；第二中间导向总成包括第四上限位滚动机构、第四侧限位滚动机构；本发明通过下、上导向限位总成固定消防拉梯，使消防拉梯稳固、安全，同时增加第一、第二中间导向总成总成进行滚动，使用时方便伸缩，减少人力操作，增加使用寿命。
