Problems solved by technology

However, when the ladder is in use, the two ladder frames need to be opened and supported on the ground, which requires a large working space
In addition, the use heights of the above two kinds of ladders are fixed, so that their use occasions are greatly limited
When it is necessary to take and place high objects, a longer ladder needs to be used. Due to its large size and high center of gravity, the longer ladder is less safe to use, and it is inconvenient to carry, and it takes up more space during storage.

Embodiment Construction

[0015] see figure 1 , the telescopic ladder 100 according to the embodiment of the present invention includes a ladder frame 10 , two base assemblies 30 disposed at one end of the ladder frame 10 , and two support assemblies 50 supported between the ladder frame 10 and the two base assemblies 30 . The ladder frame 10, the base assembly 30 and the support assembly 50 together form a triangular support structure.

[0016] The ladder frame 10 includes two sleeve rods 12 arranged parallel to each other, two telescopic rods 14 accommodated in the two sleeve rods 12 respectively, and a plurality of transverse rods 14 straddling between the two sleeve rods 12 and the two telescopic rods 14. The rod 16 and the locking assembly 18 fixed on one end of the cross rod 16 .

[0017] Please also see figure 2 The sleeve rod 12 is roughly in the shape of a hollow rectangular rod, and a receiving groove 121 with a cross-section of "I" shape is opened in the axial direction, and the receiving...

Abstract

A telescopic ladder comprises two supporting components and a ladder frame supported by the supporting components, wherein the ladder frame comprises two parallel sleeve rods, two telescopic rods detachably accommodated into the corresponding sleeve rods respectively, and a plurality of transverse rods detachably arranged between the two sleeve rods and the two telescopic rods at intervals, wherein each telescopic rod is adjustably accommodated into the corresponding sleeve rod to enable the ladder frame to adopt a telescopic structure; each supporting component comprises a cylinder body and a supporting piece telescopically connected onto the cylinder body; each cylinder body is detachably connected to the corresponding sleeve rod; each supporting piece can stretch out of or retract into the interior of the corresponding cylinder body under the driving action of the corresponding cylinder body, or part of each supporting piece stretches out of the corresponding cylinder body, so as to adjust the supporting height of the ladder frame. The telescopic ladder is small in occupied space and high in use safety during operation.

Description

technical field [0001] The invention relates to a ladder, in particular to a telescopic ladder. Background technique [0002] A common ladder is a single ladder frame structure, which includes two ladder bars arranged parallel to each other and a cross bar spanning between the two ladder bars, and the cross bar serves as a supporting step. When the ladder with this single ladder frame structure is in use, since it has no fixed structure, it needs to lean against the support to stand, which is easy to topple over and has low safety in use. In order to enhance the use safety of the ladder, a herringbone ladder has appeared. However, when the ladder is in use, the two ladder frames need to be opened and supported on the ground, which requires a large working space. In addition, the use heights of the above two kinds of ladders are fixed, so that their use occasions are greatly limited. When it is necessary to take and place items in high places, a longer ladder needs to be u...
