Steadily supported ladder
The invention provides a steadily supported ladder, and belongs to the technical field of ladders. The problems existing in an existing ladder are solved. According to the steadily supported ladder, lock catches are fixedly installed at the two ends of each pedal of the ladder, the pedals are fixed to ladder legs through telescopic devices on the lock catches at the two ends, the telescopic devices can be further used for adjusting the telescopic state of the ladder legs, gear transmission holding devices are arranged on the lock catches, the gear transmission holding devices enable the lock catches to be stably held on the ladder legs, a single-face ladder and a supporting leg are connected through a locking device, the locking device enables the relative positions of the single-face ladder and the supporting leg to be locked, the ladder further comprises an unlocking device which is used for unlocking the single-face ladder and the supporting leg so that the single-face ladder and the supporting leg can rotate relative to each other, and the ends, making contact with the ground, of the ladder legs and the supporting leg are further provided with universal ground gripping structures. The steadily supported ladder has the advantages of flexibility, reliability, high safety, high stability and versatility.
本发明提供了一种稳固支撑的梯子，属于梯子技术领域。它解决了现有梯子所存在的问题。本梯子的每个踏板两端均固定安装有锁扣，踏板通过两端锁扣上的伸缩装置固定到梯腿上，伸缩装置还可用于调节梯腿的伸缩状态，锁扣上设置有齿轮传动抱紧装置，齿轮传动抱紧装置使锁扣稳固抱紧在梯腿上，所述单面梯和支撑腿之间通过一个锁定装置连接，锁定装置使单面梯和支撑腿之间的相对位置保持锁定，梯子上还包括一个解锁装置，用于解除单面梯和支撑腿之间的锁定使单面梯和支撑腿之间可相对转动，梯腿和支撑腿与地面接触端还设置有一万向抓地结构。本发明灵活可靠，安全性和稳定性高，具有多用性。
