Abstract
The invention provides a telescopic ladder mainly including a first ladder, a second ladder, a third ladder, a locking apparatus and a pair of telescopic slide ways and being characterized in that: the telescopic slide ways are respectively disposed at two sides of the second ladder, wherein the internal sides of the telescopic slide ways are slide ways of the first ladder and the external sides of the telescopic slide ways are the slide ways of the second ladder. The first ladder is fixedly connected to the second ladder through the locking apparatus and the third ladder is fixedly connected to the second ladder through the locking apparatus. The telescopic ladder is simple in structure, is greatly reduced in size after being folded so that the telescopic ladder is convenient to store and carry.
Description
Technical field
The present invention relates to ladder technical field, especially a kind of scalable cat ladder.
Background technology
Cat ladder is the conventional apparatus of a kind of family and the maintenance of outdoor occasion.In existing cat ladder, there is the simple cat ladder of single row type, need to rely on body of wall or other supporters and could use; Also have double-row type cat ladder, self can stand.No matter be single row type or double-row type, no matter be simple not Foldable type or Foldable type, the bulk after it is folding is still very large, is not easy to deposit and carry.
Summary of the invention
The object of this invention is to provide a kind of scalable cat ladder that can fold and draw in.
Technical scheme of the present invention is: a kind of scalable cat ladder, mainly comprise the first ladder, the second ladder, the 3rd ladder, locking device and flexible road, it is characterized in that: described second ladder both sides are provided with flexible road, it is the slideway of the first ladder inside described flexible road, outside is the slideway of the 3rd ladder, described first ladder is fixedly connected with the second ladder by locking device, and described 3rd ladder is fixedly connected with the second ladder by locking device.
Further, slipmat is provided with below described 3rd ladder.
The advantage that the present invention has and good effect are: structure of the present invention is simple, and after flexible, bulk reduces greatly, is convenient to deposit and carry.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure:
1, the first ladder 2, second ladder 3, the 3rd ladder
4, flexible road 5, locking device 6, slipmat
Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the invention will be further described.
As shown in Figure 1, the invention provides a kind of scalable cat ladder, mainly comprise the first ladder 1, second ladder 2, the 3rd ladder 3, locking device 5 and flexible road 4.Described second ladder 2 both sides are provided with flexible road 4, it is the slideway of the first ladder 1 inside described flexible road 4, outside is the slideway of the 3rd ladder 3, and described first ladder 1 is fixedly connected with the second ladder 2 by locking device 5, and described 3rd ladder 3 is fixedly connected with the second ladder 2 by locking device 5.
Further, described 3rd ladder 3 is provided with slipmat 6 below.
The course of work of the present invention: during use, the first ladder 1 carries out flexible pulling open by flexible road 4 and the second ladder 2, and the 3rd ladder 3 also carries out flexible pulling open by flexible road 4 and the second ladder 2, is fixed after pulling open with locking device 5.
Structure of the present invention is simple, and after flexible, bulk reduces greatly, is convenient to deposit and carry.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
