Detailed Description

The embodiments of the present invention will be described in further detail with reference to the drawings and examples. The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model.

In the description of the present invention, "a plurality" means two or more unless otherwise specified; the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the utility model. In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, e.g., as being fixed or detachable or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 to 5, the telescopic insulating ladder according to the embodiment includes a plurality of ladder assemblies 1 inserted into each other, each ladder assembly 1 includes two vertical tubes 2 and a horizontal rod 3, the ladder assemblies 1 are inserted into each other through the vertical tubes 2, two ends of the horizontal rod 3 are both provided with a moving cavity, an inserted rod 4 is arranged in the moving cavity and can move left and right, a spring 5 tending to force the inserted rod 4 to move towards the vertical tube 2 is arranged inside the moving cavity, the upper portion of the vertical tube 2 is provided with a through hole in cooperation with the inserted rod 4, the lower portion of the vertical tube 2 is provided with an insertion hole 21 in cooperation with the inserted rod 4, two ends of the bottom of the horizontal rod 3 are both hinged downwards with a pressing rod 6, a poking hole 41 is arranged on the inserted rod 4, and a poking rod 61 capable of being clamped in the poking hole 41 is arranged at the upper end of the pressing rod 6; when the ladder component 1 extends out and the inserting holes 21 move to coincide with the inserting rods 4, the springs 5 drive the inserting rods 4 to be inserted into the inserting holes 21 to fix the vertical pipes 2; when the ladder assembly 1 needs to be retracted, the pressure rod 6 of the lowermost ladder assembly 1 can be rotated, the shifting rod 61 moves in the shifting hole 41 to drive the inserting rod 4 to move in the moving cavity, so that the inserting rod 4 is separated from the vertical tube 2, then the next lower ladder assembly 1 moves to fall, the pressure rod 6 on the cross rod 3 of the next lower ladder assembly 1 touches the cross rod 3 of the lowermost ladder assembly and then rotates upwards, the inserting rod 4 is shifted back, then the ladder assemblies 1 are sequentially unlocked from bottom to top, and the ladder assemblies 1 sequentially fall and retract, so that the operation is convenient;
