Platform extension ladder
The invention discloses a platform extension ladder. The platform extension ladder comprises an upper ladder assembly; the upper ladder assembly is a herringbone ladder; slidable lower ladder assemblies are arranged on a front body and a rear body of the herringbone ladder correspondingly; the front body and the rear body of the herringbone ladder and the lower ladder assemblies each comprise twosupporting columns and a plurality of steps arranged between the two supporting columns; first sliding grooves are formed in the outer side faces of the supporting columns on one side of the front body and one side of the rear body of the herringbone ladder correspondingly, and first sliding blocks are fixedly arranged at the lower ends of the supporting columns on one side of the front body and one side of the rear body of the herringbone ladder correspondingly; second sliding grooves are formed in the outer side faces of the supporting columns of the lower ladder assemblies, wherein the supporting columns are on the same side as the supporting columns, provided with the first sliding grooves, of the herringbone ladder; second sliding blocks are fixedly arranged on the positions, at the upper ends of the second sliding grooves, of the upper ends of the lower ladder assemblies; the first sliding blocks are slidably arranged in the second sliding grooves; the second sliding blocks are slidably arranged in the first sliding grooves; and the lower ends of the front body and the rear body of the herringbone ladder are provided with plug pin lock devices and connecting and fixing devices in locking connection with the lower ladder assemblies corresponding to the front body and the rear body of the herringbone ladder. In this way, the platform extension ladder is simple in structure,convenient to operation, more portable and more extensive in function.
本发明公开了一种平台伸缩梯，伸缩梯包括：上梯组件；上梯组件为人字梯；人字梯的前身和后身上均设有可滑动的下梯组件；人字梯的前身、人字梯的后身和下梯组件均包括：两个支柱和设置在两个支柱之间的多个台阶；人字梯的前身和后身一侧的支柱的外侧面均设有第一滑槽，且下端均固定设有一第一滑块；下梯组件与人字梯设有第一滑槽的同一侧支柱的外侧面设有第二滑槽；下梯组件的上端位于第二滑槽的上端固定设有第二滑块；第一滑块滑动设置在第二滑槽内；第二滑块滑动设置在第一滑槽内；人字梯的前身和后身下端设有与其对应的下梯组件之间锁定连接的插销锁装置和连接固定装置。通过上述方式，本发明结构简单，操作方便，更便携作用更广泛。
