Although the above patent document solves the problem of the detachable stairway, there are technical problems as follows: because the portable house faces the problem of being dismantled at any time and installed at any time, when moving, the householder needs to move the luggage into the portable house again, and the luggage is very inconvenient to move on the stairs.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve prior art's problem, provide a detachable prefabricated stair, realized changing stair into the slide, make things convenient for the resident to carry luggage.

In order to solve the technical problem, the technical scheme of the utility model is that: a detachable prefabricated staircase comprises three rows of oblique beams, treading pieces and supporting pieces for supporting the treading pieces, wherein the oblique beams, the treading pieces and the supporting pieces are arranged side by side; it has a set of piece of trampling to rotate in proper order from last co-position department to down between two adjacent rows of sloping beams, with arbitrary adjacent two-layer piece of trampling in the group, the lower floor tramples a front end and surpasss the upper front end of trampling the piece, support piece joggle is trampling between the piece with arbitrary adjacent two-layer in the group, trample a transversal parallelogram shape of personally submitting, with arbitrary adjacent two-layer footboard piece in the group round the rotation point after, the upper front end of trampling the piece and the rear end that the piece was trampled to the lower floor form level and smooth form.

Furthermore, a base is arranged on the oblique beam, a rotating pin is arranged on the base, and the rear end of the treading piece is hinged to the base through the rotating pin.

Furthermore, the top rear side and the bottom front side of the treading piece are provided with mortises, and two ends of the supporting piece are respectively provided with a tenon.

Further, the guardrail device is further included.

Further, the guardrail device comprises a plurality of inclined railings and a plurality of vertical railings, the connection can be dismantled between any two inclined railings, any inclined railing can be dismantled with any vertical railing and is connected, and any vertical railing and oblique beam can be dismantled and are connected.

The beneficial effects are that: simple structure to use with this structure cooperation is the ladder that every inspection shaft all can be equipped with, need not to cut a hole groove in addition, great reduction work load.

Detailed Description

The following will combine the embodiment to further explain in detail the technical solution of the detachable prefabricated staircase related to the present invention.

A detachable prefabricated staircase according to the embodiment shown in fig. 1-4, comprising three rows of oblique beams 1, treading members 2 and supporting members 3 for supporting the treading members 2, which are arranged side by side; it has a set of piece 2 of trampling to rotate in proper order from last co-position department to lower between two adjacent rows of sloping 1, with arbitrary adjacent two-layer piece 2 of trampling in the group, the lower floor tramples 2 front ends and surpasss the front end that the piece 2 was trampled on the upper strata, 3 joggles of support piece are between arbitrary adjacent two-layer piece 2 of trampling in the same group, trample 2 transversal parallelogram shape of personally submitting, with arbitrary adjacent two-layer piece of footboard in the group round the rotation point after, the front end that the piece 2 was trampled on the upper strata and the rear end that the piece 2 was trampled to the lower floor form level and smooth form.

When the device is used, if luggage needs to be carried, the supporting pieces 3 in the same group are taken out, the treading pieces 2 rotate downwards around the rotating point, the cross sections of the treading pieces 2 are in a parallelogram shape, and the front ends of the treading pieces 2 in the lower layer exceed the front ends of the treading pieces 2 in the upper layer, so that the treading pieces 2 in any two adjacent layers are smooth, the front end of the treading piece 2 in the upper layer is just right smooth with the rear end of the treading piece 2 in the next layer, and the stairs are changed into a slide way; because the other group of the treading pieces 2 does not change the shape, the householder can go upstairs along the treading pieces 2 on one side of the stair-shaped, and the luggage is dragged upstairs from the slide way, thereby solving the problem that the luggage carrier is hard to go upstairs after the movable board house is moved

In this embodiment, the inclined beam 1 is provided with a base 4, the base 4 is provided with a rotating pin, and the rear end of the treading member 2 is hinged to the base 4 through the rotating pin; the top rear side and the bottom front side of the treading piece 2 are provided with mortises 5, and two ends of the supporting piece 3 are respectively provided with tenons 6.

The working principle is as follows: when the device is used, the support piece 3 is taken out of the two adjacent layers of treading pieces 2, the treading pieces 2 are rotated, and the treading pieces 2 rotate around the rotating pin, so that the front end of the treading piece 2 on the previous layer is contacted with the rear end of the treading piece 2 on the next layer to form a slide way; after the use, the treading piece 2 is rotated, and the tenon 6 of the supporting piece 3 is inserted into the mortise 5 of the treading piece 2 to form the stair.

In the embodiment, the guardrail device is further provided; the guardrail device includes a plurality of oblique railings 7 and a plurality of vertical railing 8, can dismantle the connection between two arbitrary oblique railings 7, arbitrary oblique railing 7 can dismantle with arbitrary vertical railing 8 and be connected, arbitrary vertical railing 8 can dismantle with sloping 1 and be connected.

When the guardrail device is used, the guardrail device can be detachably arranged on the oblique beam 1, so that a resident can go upstairs and downstairs more safely.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
