Description

Novel stair structure

Technical Field

The invention relates to the technical field of stairs, in particular to a novel stair structure.

Background

In schools, old communities and public buildings with few building layers and low building heights, direct elevators or escalators cannot be installed generally, most of stairs are integrally formed and have a stair structure, and people carrying hand-pulling boxes need to continuously move the hand-pulling boxes in the process of climbing the stairs, so that the hand-pulling boxes need not small physical strength, and the hand-pulling boxes are very difficult for the old, the young, the pregnant women and the women.

In order to solve the problems, a novel stair structure is provided.

Disclosure of Invention

The invention aims to solve the problems in the background art and provides a novel stair structure.

In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides a novel stair structure, includes the main stair and sets up the movable groove at the main stair stiff end, the main stair is a plurality of fixed ladders that rise gradually and integrated into one piece constitutes, vice stair constitute for a plurality of movable ladders that rise gradually and fixed connection, the rotation ware is installed to the bottom of movable groove, the movable groove rotates with vice stair through rotating the ware and is connected, the upper end inner wall of movable groove rotates installs the oil hydraulic cylinder, the flexible end and the vice ladder of oil hydraulic cylinder rotate to be connected, the activity ladder includes mutually perpendicular's vertical face and horizontal plane, the radius has two arcs, one of them on the activity ladder be equipped with the hand-drawing case on the activity ladder.

In the novel stair structure, the auxiliary stair is a wooden stair.

In the novel stair structure, the width of the two arc-shaped grooves is larger than that of the hand-pulled box.

In foretell novel stair structure, the lower extreme of vice stair is equipped with first inclined plane, the lower extreme of main stair is equipped with the second inclined plane, the upper end of activity groove is equipped with from last third inclined plane, transition face and the fourth inclined plane that connects gradually extremely down.

Compared with the prior art, this novel stair structure's advantage lies in:

when the hand pulling box needs to be used, the telescopic end of the oil hydraulic cylinder is completely retracted to drive the auxiliary stair to rotate for a certain angle, the first inclined plane is parallel to the fourth inclined plane, the horizontal plane on the movable ladder forms a standing plane, the hand pulling box can be completely and temporarily placed on the horizontal plane when climbing fatigue occurs, compared with the plane on the side of the stair in the prior art, the hand pulling box can be prevented from sliding downwards randomly, and the auxiliary stair can be used for climbing like the main stair.

Drawings

Fig. 1 is a schematic structural view of a novel stair structure according to the present invention from top view;

FIG. 2 is a perspective view of the novel stair structure with auxiliary stairs at the side of the novel stair structure in a normal use state;

fig. 3 is a structural perspective view of the side surface of the novel stair structure auxiliary stair in a special use state.

In the figure: the stair comprises a main stair 1, a fixed stair 11, an auxiliary stair 2, a movable stair 21, a vertical surface 22, a horizontal surface 23, an arc-shaped groove 24, a movable groove 3, an oil hydraulic cylinder 4, a rotator 5 and a hand-pulling box 6.

Detailed Description

The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

Examples

Referring to fig. 1-3, a novel stair structure, including main stair 1 and the movable trough 3 of setting at main stair 1 stiff end, main stair 1 is a plurality of fixed ladders 11 that rise gradually and integrated into one piece constitute, vice stair 2 is a plurality of movable ladders 21 that rise gradually and fixed connection constitute, rotator 5 is installed to the bottom of movable trough 3, for prior art, movable trough 3 rotates with vice stair 2 through rotator 5 and is connected, oil hydraulic cylinder 4 is installed in the rotation of the upper end inner wall of movable trough 3, the flexible end of oil hydraulic cylinder 4 rotates with vice ladder 2 and is connected, movable ladder 21 includes mutually perpendicular's vertical face 22 and horizontal plane 23, the radius has two arc walls 24 on the movable ladder 21, be equipped with hand-drawing case 6 on one of them movable ladder 21.

The auxiliary stairs 2 are wooden stairs, and are convenient and easy to use.

The width of the two arc-shaped grooves 24 is larger than that of the hand-pulled box 6, and the size of the hand-pulled box 6 in the market is completely met.

The lower extreme of vice stair 2 is equipped with first inclined plane, and the lower extreme of main stair 1 is equipped with the second inclined plane, and the upper end of activity groove 3 is equipped with from last third inclined plane, transition face and the fourth inclined plane that connects gradually down, and the space size of activity groove 3 is for being a bit bigger than the space size of vice stair 2.

When the invention is used normally, the telescopic end of the oil cylinder 4 is in a completely extended state, the first inclined plane on the auxiliary stair 2 is parallel to the second inclined plane of the main stair 1, the second inclined plane and the third inclined plane are in a nearly parallel state, when the invention is needed, the telescopic end of the oil cylinder 4 is completely retracted to drive the auxiliary stair 2 to rotate for a certain angle, the first inclined plane is parallel to the fourth inclined plane, the horizontal plane 23 on the movable ladder 21 forms a standing plane, when climbing fatigue is accumulated, the hand pulling box 6 can be completely and temporarily placed on the horizontal plane 23, compared with the plane on the side of the stair in the prior art, the hand pulling box can be prevented from randomly sliding downwards, and the auxiliary stair 2 can also be used in a climbing way like the main stair 1.

It should be noted that the width of the arc-shaped slots 24 is fully suitable for the hand-pulled box 6 with a high chassis, and for the hand-pulled box 6 with a lower chassis, the part of the movable step 21 between the two arc-shaped slots 24 can be removed to form a wider pulling area (wider arc-shaped slots 24).

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
