Embodiment Construction

[0009] A specific embodiment of the present invention is described with reference to the accompanying drawings.

[0010] figure 1 It is a structural schematic diagram of the present invention. The left ladder frame 1 and the right ladder frame 2 have ladder holes corresponding to each other, the ladder holes can be passed by the cross bar 3, and the left and right sides of the cross bar 3 have cross bar holes 4, 5 for the hole nails 6 to pass through, thereby To the role of the fixed crossbar. The distance between the ladder holes on the left and right ladder frames is 10 cm. When a person with a tall stature uses it, a cross bar can be arranged at intervals of a ladder hole; when a child with a small stature uses the ladder frame, a cross bar can be continuously arranged on the ladder holes.

[0011] The multi-hole ladder of the present invention changes the fixed and single structure of the traditional ladder, and provides a multi-hole ladder with adjustable cross bars, w...

Abstract

The invention aims to solve the problem that the cross bar separation distance of a ladder cannot be adjusted, and provides a multi-hole ladder. According to the multi-hole ladder provided by the invention, corresponding ladder holes in isometric arrangement are formed in ladder frames at the two sides of the ladder, and the separation distance between the ladder holes can be 8-20cm. The ladder also comprises detachable cross bars. When an adult uses the ladder, the separation distance between the cross bars can be set to be larger; and when a child uses the ladder, the separation distance between the cross bars can be set to be smaller in consideration of the body height of the child. The ladder provided by the invention can be made of conventional materials including stainless steel and the like for manufacturing ladders. The ladder provided by the invention has the beneficial effects that the characteristic of fixed and single structure of the conventional ladder is changed, the multi-hole ladder with adjustable cross bars is provided, and the separation distance between the cross bars of the ladder can be adjusted according to the body heights of users.

Description

technical field [0001] The present invention relates to a porous ladder. Background technique [0002] A ladder is a commonly used climbing tool. The design structure of the ladder in daily life is fixed and single. The distance between the crossbars in the middle of the ladder cannot be adjusted. One ladder cannot be used by people of different age groups. Contents of the invention [0003] The object of the present invention is to solve the problem that the distance between the crossbars of the ladder cannot be adjusted, and to provide a multi-hole ladder. [0004] In the ladder of the present invention, there are corresponding equidistantly arranged ladder holes on the ladder frames on both sides, and the distance between the ladder holes can be a value between 8-20 centimeters. The ladder of the present invention also includes a loadable and detachable cross bar. When an adult uses the ladder, the distance between the crossbars can be set larger; and when a child use...
