Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] Such as figure 1 and figure 2 As shown, a combination ladder of the present invention includes a cross bar 1 and a longitudinal bar 2, the cross bar 1 and the longitudinal bar 2 are detachable assembly structures, the longitudinal bar 2 is provided with a socket 4, and both ends of the cross bar 1 are provided The projection 3 that is compatible with the socket 4 is provided with a steel bar 5 inside the longitudinal bar 2, and the distance between the adjacent sockets 4 on the longitudinal bar 2 is 30cm.

[0014] In this embodiment, when the ladder is not in use, the cross bar 1 and the longitudinal bar 2 are disassembled and placed, which can save storage space; In the socket 4, because the socket 4 is a trapezoid with a narrow outer mouth and a wide inner mouth, the crossbar 1 will be placed in the socket 4 and will fit closely, which is safe and reliable ...

Abstract

The invention discloses a combined ladder which comprises cross rods and longitudinal rods, wherein the cross rods and the longitudinal rods form a detachable combined structure, each longitudinal rod is provided with embedding mouths, and two ends of each cross rod are provided with bulges matched with the embedding mouth. When the combined ladder is used, the number of the cross rods to be installed can be determined according to the escalading height, the cross rods and the longitudinal rods are assembled together in a matching way through the embedding mouths and the bulges, thus the combined ladder is not only flexible and convenient, but also safe and reliable; and after the ladder is used, the cross rods and the longitudinal rods can be detached and stored, thus the occupied space can be reduced.

Description

technical field [0001] The invention relates to a ladder, in particular to a convenient and flexible combined ladder. Background technique [0002] A ladder is a daily utensil, with two longitudinal bars as the sides, and a cross bar suitable for climbing is crossed in the middle for climbing. Existing ladder, its horizontal bar and vertical bar are the integral body that is fixedly assembled together, when not using ladder, ladder occupies larger space, and is inconvenient to store and carry, has brought a lot of inconvenience to people's life. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a combined ladder that is easy to use, flexible and saves storage space. [0004] Technical solution: In order to achieve the above object, a combination ladder of the present invention includes a horizontal bar and a vertical bar, the horizontal bar and the vertical bar are detachable...
