Abstract
The invention discloses a contraction folding ladder, which comprises a fixed frame, a connecting frame and a movable frame, wherein the fixed frame is fixedly arranged on a fixed object and comprises two fixing rods in parallel arrangement; the connecting frame is movably connected with the fixed frame; the movable frame comprises support rods and telescopic rods connected with the support rods through telescopic elements; the support rods and the fixing rods are in one-to-one corresponding arrangement and are movably connected; the telescopic rods are movably connected with the connecting frame through a chain via a pedal; when the contraction folding ladder is in an unfolded state, the end parts of the support rods are flushed with the end parts of the fixing rods, or are higher than the end parts of the fixing rods. The contraction folding ladder has the advantages that the fixed frame is fixedly arranged on a bed frame of a student dormitory; the rest influencing sound given when people get on or get off from a bed and the swinging generated in the process can be eliminated; a certain degree of potential safety hazards is greatly reduced; the ladder can be contracted and folded; the occupied space is reduced; the placement is convenient.
Description
Technical field
The present invention relates to ladder field, particularly one shrinks folding ladder.
Background technology
It is all two-layer up and down for being directed to bed supporting in most of student dormitory, only has one to be fixed on the ladder of bedstead for climbing, very inconvenient up and down.Particularly old bed, up and down period can send very loud sound and produce rocking to a certain extent, greatly impact study and having a rest, and there is certain potential safety hazard.But use general folded ladder to be little reality at student dormitory, and take certain space, make living space originally become more nervous.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the present invention is to provide and a kind of shrink folding ladder, thus overcome and take up room, there is security hidden trouble.
For achieving the above object, the invention provides a kind of contraction folding ladder, comprising: fixed mount, it is fixed on fixed object, and described fixed mount comprises two fixed bars be arranged in parallel; Link, it is flexibly connected with described fixed mount; And adjustable shelf, it comprises support bar and by the connected expansion link of extensible member, described support bar and described fixed bar are that one_to_one corresponding is arranged, and are flexibly connected with described fixed bar, and described expansion link is by pedal and described link active link; When described contraction folding ladder is in open mode, the end of described support bar is concordant with the end of described fixed bar, or higher than the end of described fixed bar.
Preferably, in technique scheme, described extensible member comprises: extension sleeve, and it is fixed on described support bar, and described extension sleeve is provided with draw-in groove; And Fastener, it comprises shell fragment and is located at the buckle on this shell fragment, and described shell fragment is fixed on described expansion link, and described buckle is arranged with described draw-in groove is mutually corresponding.
Preferably, in technique scheme, described extension sleeve is provided with multiple draw-in groove in vertically arrangement.
Preferably, in technique scheme, the bottom of described expansion link is provided with castor.
Compared with prior art, the present invention has following beneficial effect: the present invention shrinks folding ladder, fixed mount is fixedly mounted on the bedstead of student dormitory, eliminates bunk bed and send rocking of producing in the sound and process that impact has a rest, greatly reduce and there is potential safety hazard to a certain degree.Can shrink folding, saving takes up room, convenient arrangement.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole manual and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or ingredient, and do not get rid of other element or other ingredient.
As shown in Figures 1 to 5, the one according to the specific embodiment of the invention shrinks folding ladder, comprising: fixed mount comprises two fixed bars be arranged in parallel 1, connects between fixed bar by connecting rod 2.Fixed mount is fixedly mounted on bedstead.Link 3 upper end and fixed bar 1 hinged.Adjustable shelf comprises support bar 4 and by the connected expansion link 6 of extensible member 5, and support bar 4, and to be flexibly connected with fixed bar 1 for one_to_one corresponding is arranged with fixed bar 1, and expansion link 6 passes through pedal 7 and link 3 active link.
Stretched outward by adjustable shelf, open contraction folding ladder, shrink folding ladder when being in open mode, the end of support bar 4 is concordant with the end of described fixed bar 1, or higher than the end of described fixed bar.Support bar 4 and fixed bar 1 form leg-of-mutton supporting mechanism, can prevent from shrinking folding ladder when opening and using, and support bar 4 down moves, and cannot use contraction folding ladder.When folding ladder is in open mode, pedal 7 is also parallel shape along with the movement of adjustable shelf and ground, and when folding ladder shrinks, pedal 7 is also vertical configuration along with the movement of adjustable shelf and opposite, achieves the contraction of pedal 7.
Preferably, extensible member 5 comprises: extension sleeve 51 is fixed on support bar 4, and extension sleeve 51 is provided with draw-in groove 52.Fastener comprises shell fragment 53 and is located at the buckle 54 on this shell fragment, and shell fragment 53 is fixed on expansion link 6, and buckle 54 is arranged with draw-in groove 52 is mutually corresponding.When opening folding ladder, stretched outward by expansion link 6, when moving to assigned address, buckle is due to the effect of shell fragment, and buckle 54 springs in draw-in groove 52, the position of fixing expansion link.When closed folding ladder, upwards push away expansion link 6, buckle is due to the effect of shell fragment, and buckle 54 departs from draw-in groove 52, i.e. movable expanding bar, realizes shrinking the folding of folding ladder.
Preferably, extension sleeve 51 is provided with multiple draw-in groove 52 in vertically arrangement, as required, can change contraction folding ladder and open amplitude.
Preferably, the bottom of expansion link 6 is provided with castor 8, shrinking or opening in the process of folding ladder, owing to being provided with castor 8, if expansion link moves more convenient, plays the effect of saving strength.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
