Detailed Description

In order to more clearly illustrate the embodiments of the present invention and the technical solutions in the prior art, the following description will explain specific embodiments of the present invention with reference to the accompanying drawings. It is obvious that the drawings in the following description are only some examples of the invention, and for a person skilled in the art, other drawings and other embodiments can be obtained without inventive effort, and the invention is not limited to this example.

Referring to fig. 1, fig. 2, fig. 3, fig. 4, the utility model discloses a square box ladder of specific embodiment, including ladder body 1, ladder body 1 includes a plurality of end to end connection's ladder unit 11, ladder unit 11 includes a set of bracing piece 12 that sets up side by side to and connect the ladder pole 13 between bracing piece 12 side by side, still include the pedestal box body 2 that is connected with ladder body 1 and is equipped with accommodation space, can fold each other in the horizontal direction through the gliding mode between the adjacent ladder unit 11, also can rotate to fold from top to bottom through the junction to reduce ladder body 1's space volume, and then make ladder unit 11 can be held in accommodation space of pedestal box body 2. The base box body 2 comprises a first box body box plate 21 hinged with the ladder body 1, a second box body box plate 22, a third box body box plate 23, a fourth box body box plate 24 and a fifth box body box plate 25, wherein the second box body box plate 22, the third box body box plate 23, the fourth box body box plate 24 and the fifth box body box plate 25 are hinged with the first box body box plate 21 respectively.

Still include a plurality of settings in the locating part 3 that the edge of base box body 2's edges and corners edge is used for maintaining base box body 2's box body form, locating part 3 includes spacing tooth 31 and spacing knot 32. First box body box board 21, second box body box board 22, third box body box board 23, fourth box body box board 24, fifth box body box board 25 come the amalgamation of each other through locating part 3 in order to make up into a complete base box body 2 to second box body box board 22 wherein, fourth box body box board 24 all set up to two segmentation articulated metal sheets each other, so that second box body box board 22, fourth box body box board 24 can also cover the upper portion terminal surface of base box body 2 when the amalgamation.
