Ladder section on inner side of extension ladder
The invention provides a ladder section on the inner side of an extension ladder. The extension ladder at least comprises two adjacent ladder sections which can slide relatively, and each ladder section at least comprises two vertical segments and a horizontal segment connected between the two vertical segments; the vertical segments of the ladder section on the inner side are slidably arranged onthe vertical segments of the ladder section on the outer side; the ladder section on the inner side further comprises a first elastic locking device arranged on the horizontal segment of the ladder section on the inner side; the first elastic locking device comprises teeth and a first elastic device connected with the teeth and controlling the teeth to move; the ladder section on the outer side further comprises racks arranged on the vertical segments of the ladder section on the outer side; and the racks are engaged with the teeth. Through engagement or locking of the racks and the teeth, the two adjacent ladder sections are adjusted to the required height, and thus the middle position is adjusted.
本发明提供了一种伸缩梯的内侧的梯节，所述伸缩梯至少包括：相邻的两个能相对滑动的梯节，每个梯节至少包括：两个竖段和连接在两个竖段之间的横段；内侧的梯节的竖段能滑动的设置在外侧的梯节的竖段上；内侧的梯节还包括：设置在内侧的梯节的横段上的第一弹性锁紧装置；所述第一弹性锁紧装置包括齿牙和连接并控制所述齿牙移动的第一弹性装置；外侧的梯节还包括：设置在外侧的梯节的竖段上的齿条；所述齿条与所述齿牙相啮合。本发明利用齿条和齿牙的咬合或锁紧，将相邻两个梯节调整到需要的高度，从而实现了中间位置的调整。
