The specific embodiment

Below in conjunction with accompanying drawing, to this novel above-mentionedly is described in more detail with other technical characterictic and advantage.

See also Fig. 1, shown in Figure 2, the utility model mainly provides a kind of multifunctional ladder, be to include a body 1, at least one step assembly 2 and number to receive body 3, wherein:

Described body 1 is to become a ㄇ shape by the two ends that two poles 11 with same configuration are separately fixed at a cross bar 12, the bottom of pole 11 is provided with a combined hole 111, combined hole 111 places that are positioned on the pole 11 laterally are provided with an open-work 112, and cross bar 12 is provided with more than one pivoted hole 121.

The two ends of described step assembly 2 are respectively equipped with a sleeve pipe 21 with same configuration, and sleeve pipe 21 can supply the pole 11 of body 1 or receive body 3 and insert, and sleeve pipe 21 is provided with an open-work 211.

Described number is received body 3 and is had identical construction, receive body 3 upper ends and be provided with the nose bar 31 that to combine closely with combined hole 111, laterally be provided with an open-work 311 on the nose bar 31, nose bar 31 bottoms receive that ring-type is provided with a stopper section 32 on the body 3, in order to backstop sleeve pipe 21, the bottom of receiving body 3 is provided with a combined hole 33 that can supply nose bar 31 to combine closely, and uses for another and receives body 3 combinations, and combined hole 33 places that are positioned at of receiving body 3 laterally are provided with an open-work 312.

Please cooperate again consult shown in Figure 4, supply a body 1 or number to receive the end fit with combined hole 111,312 of body 3 respectively two sleeve pipes 21 of number step assembly 2, the nose bar 31 of number being received body 3 is inserted combined

hole

111,33 respectively again, the open-work 112,211 of the open-work 311 of nose bar 31 and body 1 and step assembly 2 is involutory to penetrate for fixtures 4, number is received body 3 combine with body 1 and several step assemblies 2 and form a monolithic ladder.

See also Fig. 1 and shown in Figure 5, its pivoted hole 121 involutory confession one articulated parts 5 are penetrated two bodies, 1 subtend, an inferior end fit that two sleeve pipes 21 of a step assembly 2 is supplied a body 1 respectively with combined hole 111, the nose bar 31 of number being received body 3 is inserted combined hole 111 respectively again, the open-work 311 of nose bar 31 penetrates with the open-work of body 1 and step assembly 2 112, the 211 involutory fixtures 4 that supply, number is received body 3 and body 1 and number step assemblies 2 combine, have the seat on plane or fill up the pin chair because of the pivot joint of two cross bars 12 forms one.
