Abstract
The invention discloses a kind of movable stair, including: superposition ladder, base carrier and rotation wheel, the stair tread that described superposition ladder is wooden, plastic cement or sheet metal is made, described superposition ladder is arranged in base carrier, described base carrier is that hollow square tubes soldering forms, described rotation wheel is arranged on the back of base carrier, and the top of described base carrier is provided with a cylindrical grip, and described handle is made up of hollow metal pipe.By the way, a kind of movable stair that the present invention points out, wheel is arranged on the back side, promotes more convenient, and sound construction, the area contacted with ground is big, and good stability during work is safe to use.
Description
Technical field
The present invention relates to movable stair field, particularly relate to a kind of movable stair.
Background technology
Movable stair is exactly transportable stair, it is simple to people carry out various climbing.Movable stair in supermarket, warehouse and library relatively common, facilitate staff to carry out ascending a height operation.Movable stair substantially can be divided into belt wheel stair and portable stairway according to move mode, and belt wheel stair are exactly to be mounted with in the bottom of stair to rotate wheel, facilitate the movement of stair, and portable stairway mainly uses the material of lightweight to make, it is simple to artificial carrying.
Belt wheel stair are mounted with to rotate wheel due to bottom, therefore transport more flexible, but poor stability during using, even if rotating and being provided with brake system on wheel, but due to problems such as contact area are little, center of gravity is high, the stair also extremely unstable of bottom belt wheel, easily rocks, and causes the operating personnel on stair or article damage.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of movable stair, good stability, conveniently moving.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of movable stair, including: superposition ladder, base carrier and rotation wheel, the stair tread that described superposition ladder is wooden, plastic cement or sheet metal is made, described superposition ladder is arranged in base carrier, described base carrier is that hollow square tubes soldering forms, described rotation wheel is arranged on the back of base carrier, the top of described base carrier is provided with a cylindrical grip, and described handle is made up of hollow metal pipe.
In a preferred embodiment of the present invention, described rotation wheel is symmetrically arranged two directional wheels.
In a preferred embodiment of the present invention, described base carrier be shaped to L-shaped.
In a preferred embodiment of the present invention, described rotation wheel is arranged on the back of base carrier.
The invention has the beneficial effects as follows: a kind of movable stair that the present invention points out, wheel is arranged on the back side, promotes more convenient, and sound construction, the area contacted with ground is big, and good stability during work is safe to use.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only some embodiments of the present invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of the present invention a kind of movable stair one preferred embodiment；
In accompanying drawing, the labelling of each parts is as follows: 1, superposition ladder, and 2, base carrier, 3, rotate wheel.
Detailed description of the invention
Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Referring to Fig. 1, the embodiment of the present invention includes:
A kind of movable stair, including: superposition ladder 1, base carrier 2 and rotation wheel 3, the stair tread that described superposition ladder 1 is wooden, plastic cement or sheet metal is made, lightweight, sound construction, described superposition ladder 1 is arranged in base carrier 2, described base carrier 2 forms for hollow square tubes soldering, described rotation wheel 3 is arranged on the back of base carrier 2, the top of described base carrier 2 is provided with a cylindrical grip, and described handle is made up of hollow metal pipe, and quality is slim and graceful, good hand touch, it is simple to promotion when movable stair tilts.
One movable stair of the present invention, described rotation wheel 3 is symmetrically arranged two directional wheels, symmetrical, good stability during transport.
Further, described base carrier 2 be shaped to L-shaped, perpendicular to the ground during use, the contact area on bottom and ground is big, and therefore staff is at stair climbing or more stable when stand operation above, and safety is high.
Further, described rotation wheel 3 is arranged on the back of base carrier 2, when carrying out, as long as stair are tilted an angle so that rotate wheel 3 and land, just can easily promote movable stair destination on earth.
In sum, a kind of movable stair that the present invention points out, compared with the stair of bottom belt wheel, structure is more firm, and stability is high, improves the safety of use.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in the scope of patent protection of the present invention.
Claims (3)
1. a movable stair, it is characterized in that, including: superposition ladder, base carrier and rotation wheel, the stair tread that described superposition ladder is wooden, plastic cement or sheet metal is made, described superposition ladder is arranged in base carrier, and described base carrier is that hollow square tubes soldering forms, and described rotation wheel is arranged on the back of base carrier, the top of described base carrier is provided with a cylindrical grip, and described handle is made up of hollow metal pipe.
