Description
Technical field
The present invention relates to flexible stair field, particularly relate to a kind of rotary extension stair of Armrest.
Background technology
Conveniently floor gap is current, and people have invented multiple stair.General stair are all fixed structures, once construct, position is difficult to variation, larger on the layout general layout impact of indoor, and the space that takies of fixed stair is large, for the family that house type is little, often adopt loft extension ladder to solve interim floor and to pass through problem.
The compact of loft extension ladder, stretches flexibly, can pack up time no, does not affect the current of bottom, more welcome in domestic consumer.What loft extension ladder in the market mainly adopted is intersects stretched out structure continuously, intensity is low, mechanical stability is poor, and most of loft extension ladder conveniently stretches and does not arrange the handrail of both sides, upper safety downstairs can not get ensureing, structure is simple and crude, has certain influence to the decorative effect in house, lacks aesthetic property.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of rotary extension stair of Armrest, sound construction, and safety is high, good decorative property.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the rotary extension stair providing a kind of Armrest, comprise: motor, directive wheel, shrink serving, telescopic sleeve pipe formula segmented column, broadstep and handrail guardrail, described telescopic sleeve pipe formula segmented column is connected in sequence by the sub-segmented column that several sections of diameter is descending, described broadstep is separately positioned on each sub-segmented column, described directive wheel is arranged on the side of motor, the end of described motor is provided with folding and unfolding wheel, the upper end of described contraction serving to be taken turns with folding and unfolding through directive wheel and is connected, the lower end of described contraction serving is connected with sub-segmented column bottom, described handrail guardrail is arranged on the top of each broadstep respectively.
In a preferred embodiment of the present invention, between described handrail guardrail, tightrope is adopted to connect successively.
In a preferred embodiment of the present invention, described directive wheel is arranged on the top of telescopic sleeve pipe formula segmented column.
In a preferred embodiment of the present invention, described sub-segmented column is that the pipe of hollow or square tube are made.
In a preferred embodiment of the present invention, the sub-segmented column that described pipe is made is respectively arranged with chute and supporting alignment pin to limit moving up and down and stoping it to rotate between sub-segmented column.
In a preferred embodiment of the present invention, described contraction serving is through the center of telescopic sleeve pipe formula segmented column.
In a preferred embodiment of the present invention, described folding and unfolding wheel is provided with brake gear.
In a preferred embodiment of the present invention, described motor is provided with circuit controller.
The invention has the beneficial effects as follows: the rotary extension stair of a kind of Armrest that the present invention points out, can the interior space restricted or no time be hidden in loft top, and moulding is graceful when launching, sound construction, facilitate personnel upper and lower, handrail is installed in addition, has ensured the safety of personnel.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of rotary extension stair one preferred embodiment of a kind of Armrest of the present invention;
Fig. 2 is the enlarged drawing of parts 8 position in Fig. 1;
In accompanying drawing, the mark of each parts is as follows: 1, motor, and 2, directive wheel, 3, shrink serving, 4, telescopic sleeve pipe formula segmented column, 5, broadstep, 6, handrail guardrail, 7, tightrope, 8, spacer pin.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of rotary extension stair of Armrest, comprise: motor 1, directive wheel 2, shrink serving 3, telescopic sleeve pipe formula segmented column 4, broadstep 5 and handrail guardrail 6, described telescopic sleeve pipe formula segmented column 4 is connected in sequence by the sub-segmented column that several sections of diameter is descending, described broadstep 5 is separately positioned on each sub-segmented column, described directive wheel 2 is arranged on the side of motor 1, the end of described motor 1 is provided with folding and unfolding wheel, the upper end of described contraction serving 3 to be taken turns with folding and unfolding through directive wheel 2 and is connected, the lower end of described contraction serving 3 is connected with sub-segmented column bottom, described handrail guardrail 6 is arranged on the top of each broadstep respectively.
The rotary extension staircase structure of a kind of Armrest of the present invention is firm, and adopt tightrope 7 to connect successively between described handrail guardrail 6, tightrope 7 adds the safety factor of pedestrian.
Further, described directive wheel 2 is arranged on the top of telescopic sleeve pipe formula segmented column 4.
Further, described sub-segmented column is that the pipe of hollow or square tube are made, and lightweight, intensity is high, the good stability of connection.
Further, the sub-segmented column that described pipe is made is respectively arranged with chute and supporting alignment pin 8 to limit moving up and down and stoping it to rotate between sub-segmented column.
Further, described contraction serving 3 is through the center of telescopic sleeve pipe formula segmented column 4.
Further, described folding and unfolding wheel is provided with brake gear, prevents the freely falling body of stair, improve the safety used.
Further, described motor 1 is provided with circuit controller, controls the flexible of telescopic sleeve pipe formula segmented column 4.
When rotary extension stair fold, serving 3 is shunk by the rotary tightening of described motor 1, described telescopic sleeve pipe formula segmented column 4 draws in section by section, the fishing rod of similar contraction after sub-segmented column draws in, be hidden in top, when scalable stair launch, described motor 1 reverses to release and shrinks serving 3, described telescopic sleeve pipe formula segmented column 4 drops down, the tightrope 7 between handrail guardrail 6 also tightens up.
In the restricted situation of the interior space, or rotary extension stair can be hidden in loft top time no, can Automatic-expanding in the needs used time, facilitate personnel upper and lower.
In sum, the rotary extension stair of a kind of Armrest that the present invention points out, stretch compared with stair with common loft, and structure is more firm, and good decorative property, safety is high.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
