Climbing ladder for children
A crawling ladder for children comprises a front supporting leg. The front supporting leg and the rear supporting leg are rotationally connected around a shaft; the front part of the standing plate is rotationally connected with the upper end part of the rear supporting leg around a second shaft; the lower end part of the upper supporting frame is rotationally connected with the upper end part of the front supporting leg around a third axis, and the upper supporting frame is rotationally connected with the standing plate around a fourth axis; the front supporting leg, the rear supporting leg, the standing plate and the upper supporting frame form a folding four-connecting-rod mechanism with an unfolding position and a folding position, and the crawling ladder for children further comprises a connecting rod lock capable of locking the folding four-connecting-rod mechanism at the unfolding position. Folding and unfolding are achieved through the folding four-connecting-rod mechanism, when the crawling ladder main frame is located at the unfolding position, the standing plate is horizontally arranged for an infant to stand, the child crawling ladder contracts front and back after being folded, the front supporting legs and the rear supporting legs draw close front and back, and the child crawling ladder is small in occupied space, convenient to store and operate and high in practicability.
一种儿童爬爬梯，包括前支撑腿；后支撑腿，所述前支撑腿与所述后支撑腿绕一轴转动连接；站板，所述站板前部与所述后支撑腿上端部绕二轴转动连接；上撑架，所述上撑架下端部与所述前支撑腿上端部绕三轴转动连接，所述上撑架与所述站板绕四轴转动连接；所述前支撑腿、所述后支撑腿、所述站板和所述上撑架形成具有展开位置和折叠位置的折叠四连杆机构，所述儿童爬爬梯还包括能够将所述折叠四连杆机构锁定于展开位置的连杆锁。本发明通过折叠四连杆机构，实现折叠和展开，当所述爬梯主架处于展开位置下，所述站板平置供幼儿站立，折叠后儿童爬爬梯前后收缩，前支撑腿与后支撑腿前后靠拢，占用空间小，便于收纳存放，操作方便，实用性强。
