Extension ladder
The invention relates to the technical field of ladders, and particularly discloses an extension ladder which comprises an extension part and a folding part. The telescopic part comprises a plurality of first transverse rods arranged horizontally and supporting rods fixedly connected to the two ends of the first transverse rods, and the supporting rods can stretch out and draw back to enable the first transverse rods to be stacked together. The folding part is provided with a second transverse rod for treading, the second transverse rod is horizontally arranged, the two ends of the second transverse rod are connected with rotating rods, the rotating rods are rotationally connected with the second transverse rod, and the ends, away from the second transverse rod, of the rotating rods are connected with the first transverse rod. The telescopic ladder has the effects that the telescopic ladder is convenient to use, and the application scene of the telescopic ladder is increased.
本申请涉及梯具的技术领域，并具体公开了一种伸缩梯，包括伸缩部和折叠部。伸缩部包括水平布设的若干第一横杆，以及固定连接于第一横杆两端的撑杆，撑杆能够伸缩并使得若干第一横杆堆叠在一起。折叠部布设有提供踩踏的第二横杆，第二横杆为水平布设，第二横杆的两端均连接有转杆，转杆与第二横杆转动连接，转杆背离第二横杆的端部连接第一横杆。本申请具有方便伸缩梯的使用，增加伸缩梯的应用场景的效果。
