Abstract
The invention discloses a rotating telescopic stair with a handrail. The rotating telescopic stair with the handrail comprises a motor, a guiding wheel, a retraction winding rope, a telescopic sleeve segmented column, stair treads and handrail guard bars. The telescopic sleeve segmented column is formed by sequentially connecting a plurality of sub segmented columns with the gradually-decreased diameters. The stair treads are arranged on the sub segmented columns respectively. The guiding wheel is arranged on one side of the motor. A winding and unwinding wheel is installed at the end of the motor. The upper end of the retraction winding rope is connected with the winding and unwinding wheel through the guiding wheel. The lower end of the retraction winding rope is connected with the bottommost sub segmented column. The handrail guard bars are installed at the upper portions of the stair treads respectively. In this way, the rotating telescopic stair with the handrail can be hidden at the upper portion of an attic when indoor space is limited or the stair is not used; when unfolded, the rotating telescopic stair with the handrail is elegant in design and firm in structure, people can conveniently walk upstairs and downstairs, and in addition, the safety of the people is ensured due to the handrail.
Description
Technical field
The present invention relates to flexible stair field, particularly relate to a kind of rotary extension stair of Armrest.
Background technology
In order to facilitate the current of floor gap, people have invented multiple stair.General stair are all fixed structures, once construct, position is difficult to variation, larger on indoor layout general layout impact, and the space that fixed stair take is large, for the little family of house type, often adopt loft extension ladder to solve the current problem of interim floor.
The volume of loft extension ladder is small and exquisite, stretches flexibly, no time, can pack up, and 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 does not arrange the handrail of both sides for convenient stretching, upper safety downstairs can not get ensureing, structure is simple and crude, and the decorative effect in house is had to certain influence, 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, and sound construction is safe, 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 that a kind of Armrest is provided, 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 descending sub-segmented column of several sections of diameters, described broadstep is separately positioned on each sub-segmented column, described directive wheel is arranged on a side of motor, the end of described motor is provided with folding and unfolding wheel, the upper end of described contraction serving is connected with folding and unfolding wheel through directive wheel, the lower end of described contraction serving is connected with sub-segmented column bottom, described handrail guardrail is arranged on respectively the top of each broadstep.
In a preferred embodiment of the present invention, between described handrail guardrail, adopt tightrope 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, pipe or square tube that described sub-segmented column is hollow are made.
In a preferred embodiment of the present invention, on the sub-segmented column that described pipe is made, be respectively arranged with chute and supporting alignment pin and limit moving up and down and stoping its rotation 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, on described folding and unfolding wheel, be provided with brake gear.
In a preferred embodiment of the present invention, on described motor, be 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 be in the interior space restricted or be hidden in loft top no time, and moulding gracefulness while launching, sound construction, facilitate personnel upper and lower, handrail is installed in addition, has been ensured personnel's safety.
Brief description of the drawings
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described 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, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, 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 positions in Fig. 1;
In accompanying drawing, the mark of each parts is as follows: 1, motor, 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
To the technical scheme in the embodiment of the present invention be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making all other embodiment that obtain 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 descending sub-segmented column of several sections of diameters, described broadstep 5 is separately positioned on each sub-segmented column, described directive wheel 2 is arranged on a 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 is connected with folding and unfolding wheel through directive wheel 2, the lower end of described contraction serving 3 is connected with sub-segmented column bottom, described handrail guardrail 6 is arranged on respectively the top of each broadstep.
The rotary extension staircase structure of a kind of Armrest of the present invention is firm, adopts tightrope 7 to connect successively between described handrail guardrail 6, and tightrope 7 has increased pedestrian's safety factor.
Further, described directive wheel 2 is arranged on the top of telescopic sleeve pipe formula segmented column 4.
Further, pipe or square tube that described sub-segmented column is hollow are made, and lightweight, intensity is high, the good stability of connection.
Further, on the sub-segmented column that described pipe is made, be respectively arranged with chute and supporting alignment pin 8 and limit moving up and down and stoping its rotation between sub-segmented column.
