The ladder body (2) is articulated with the rotating shaft (1); the rotating shaft (1) is provided with an external spline (7), while the ladder body (2) is provided with an internal spline (11) matched with the external spline (7). Compared with the prior art, the multifunctional ladder has simple structure and convenient use, and is applicable to the uneven topography.

Description

A kind of multifunctional ladder

Technical field:

The utility model belongs to multifunctional ladder, particularly the multifunctional ladder of portable band.

Background technology:

Ladder in the market is many, mainly comprises long ladder, double ladder, and double ladder is lighter, but its solar angle is fixing usually, can not adapt to different physical features, uses and also is subjected to environmental limit.

The utility model content:

Technical problem to be solved in the utility model provides a kind of easy to carry, can adapt to the multifunctional ladder of different physical features.

The technical scheme of the utility model technical solution problem is: a kind of multifunctional ladder, comprise ladder body, axis of rotation, and the ladder body is hinged by axis of rotation, and described axis of rotation is provided with external splines, the ladder body is provided with the internal spline that cooperates with it.

For the axis of rotation that makes multifunctional ladder is difficult for producing axially-movable, between cap nut and external splines, also be provided with elastomeric element, described elastomeric element is spring, elastic caoutchouc.

In order to make multifunctional ladder adapt to different physical features, foot of ladder links by the base of hinge with band self-locking universal wheel.

The flute profile of described spline is a rectangle, and the number of teeth is 8.

Height for the ease of multifunctional ladder is regulated, and is provided with the son ladder of loosing core in the bottom of ladder body, and the son ladder of loosing core detachably connects with the ladder body by the locating hole on spring holder, the sub-ladder of loosing core.

The utility model compared with prior art has simple in structurely, easy to use, is specially adapted to the uneven situation of physical features.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the utility model preferred construction schematic diagram.

Fig. 3 is the local enlarged diagram of the utility model ladder bodies top.

Fig. 4 is another embodiment of the utility model.

In Fig. 1,2,3,4,1 is axis of rotation, and 2 is the ladder body, and 3 is foot of ladder, and 4 is base, and 5 are the self-locking universal wheel, and 6 are the son ladder of loosing core, and 7 is external splines, and 8 is spring, and 9 is cap nut, and 10 is pin-and-hole, and 11 is internal spline, and 12 is spring holder, and 13 is locating hole.

The specific embodiment:

Be described in detail below in conjunction with Fig. 1,2,3,4 pairs of the utility model.

Embodiment 1: as shown in Figure 1, 2, 3, a kind of multifunctional ladder, comprise ladder body 2, axis of rotation 1, ladder body 2 is hinged by axis of rotation 1, described axis of rotation is provided with external splines 7, ladder body 2 is provided with internal spline 11 with matching, the flute profile of described spline is a rectangle, and the number of teeth is 8.

For the axis of rotation 1 that makes multifunctional ladder is difficult for producing axially-movable in use, between cap nut 9 and external splines 7, also be provided with elastomeric element 8, described elastomeric element 8 is spring, elastic caoutchouc.

When needs are adjusted the angle of multifunctional ladder, extract the alignment pin in the pin-and-hole 10, utilize the elastic force of elastomeric element 8 to make two ladder bodies 2 and axis of rotation 1 separately, after treating that the gradient angle is adjusted, axis of rotation 1 is inserted, make the external splines 7 and 2 corresponding internal spline 11 engagements of ladder body of axis of rotation 1, again alignment pin is inserted in the pin-and-hole 10, get final product.

In order to make multifunctional ladder can adapt to different physical features, foot of ladder 3 links by the base 4 of hinge with band self-locking universal wheel 5.

Embodiment 2: as shown in Figure 4, height for the ease of multifunctional ladder is regulated, also can be provided with the son ladder 6 of loosing core in the bottom of ladder body 2, spring holder 12 connects with ladder body 2 by the locating hole 13 on the son ladder 6 of loosing core, and the foot of ladder of the son ladder 6 of loosing core links by the base 4 of hinge with band self-locking universal wheel 5.
