Abstract
The utility model discloses a kind of self-supporting folding ladder, comprise main terraced body and movable joint auxiliary support bar.Described movable joint auxiliary support bar comprises two joints, be respectively the first auxiliary support bar and the second auxiliary support bar, connected by hinge axis between first auxiliary support bar and the second auxiliary support bar, the other end of the first auxiliary support bar is connected with main terraced body bottom by hinge axis, the other end of the second auxiliary support bar is connected with the waist typed through hole be arranged in the middle part of main terraced body by hinge axis, and junction is provided with locking device thereon, make movable joint auxiliary support bar and main trapezoidal become equilateral triangle, the angle on main ladder and ground reaches 60 degree of safer angles, thus make stressed 2 of original foot of ladder become a stress surface, enhance the stability of folding ladder.The utility model structure is simple, easy to use, breaks away when can effectively prevent folding ladder from using, and saves manpower, safe and reliable.
Description
Technical field
The utility model relates to a kind of self-supporting folding ladder.
Background technology
Folding ladder mainly uses during high-rise working when power system device overhauls.Higher by the equipment general distance ground of overhauling, be generally metal shell, smooth surface by maintenance electric equipment, exist during use conventional elevator and be hooked shakiness, easily break away; In addition, some overhaul of the equipments, by spacial influence, if overexerted in operating personnel's operation process, ladder also easily breaks away.In use, ladder must be placed firmly, is advisable with 60 ° ~ 70 ° with ground angle, and special messenger must be had to carry out guarding and helping.This mode waste of manpower, and and unreliable.
Utility model content
For solving the problem, the utility model discloses a kind of self-supporting folding ladder.
In order to achieve the above object, the utility model provides following technical scheme: a kind of self-supporting folding ladder, comprise main terraced body and movable joint auxiliary support bar, described movable joint auxiliary support bar comprises two joints and is respectively the first auxiliary support bar and the second auxiliary support bar, connected by hinge axis between first auxiliary support bar and the second auxiliary support bar, the other end of the first auxiliary support bar is connected with main terraced body bottom by hinge axis, the other end of the second auxiliary support bar is connected with the waist typed through hole be arranged in the middle part of main terraced body by hinge axis, and junction is provided with locking device thereon, make movable joint auxiliary support bar and main trapezoidal become equilateral triangle, the angle on main ladder and ground reaches 60 degree of safer angles, thus make stressed 2 of original foot of ladder become a stress surface, enhance the stability of folding ladder.The utility model has the advantage of simple and reasonable, easy to use, break away when can effectively prevent folding ladder from using, an independent people can use folding ladder, help on side without other staff, save manpower, safe and reliable.
Improve as one of the present utility model, the first described auxiliary support bar becomes an equilateral triangle shape with described main terraced figure after launching with the second auxiliary support bar.
Beneficial effect:
The self-supporting folding ladder structure that the utility model provides is simple, easy to use, break away when can effectively prevent folding ladder from using, and an independent people can use folding ladder, save manpower, safe and reliable, simultaneously self-supporting folding ladder of the present utility model can fold fast when not using, conveniently laying and carry.
Accompanying drawing explanation
Fig. 1 be the utility model self-supporting folding ladder actual use time structural representation;
Fig. 2 be the utility model self-supporting folding ladder finish using draw in after structural representation;
Wherein each parts are:
1 main terraced body, 2 waist typed through hole, 3 second auxiliary support bars, 4 hinge axis, 5 first auxiliary support bars, 6 locking devices.
Detailed description of the invention
Below with reference to specific embodiment, the technical scheme that the utility model provides is described in detail, following detailed description of the invention should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.
A kind of self-supporting folding ladder as described in Fig. 1 to Fig. 2, comprise main terraced body 1 and movable joint auxiliary support bar, described movable joint auxiliary support bar comprises two joints and is respectively the first auxiliary support bar 5 and the second auxiliary support bar 3, connected by hinge axis 4 between first auxiliary support bar 5 and the second auxiliary support bar 3, the other end of the first auxiliary support bar 5 is connected with main terraced body bottom by hinge axis 4, the other end of the second auxiliary support bar 3 is connected with the waist typed through hole 2 be arranged in the middle part of main terraced body by hinge axis, and junction is provided with locking device 6 thereon.
An equilateral triangle shape is formed with described main terraced body 1 after the first described auxiliary support bar 5 and the second auxiliary support bar 3 launch, the angle on main ladder and ground reaches 60 degree of safer angles, thus make stressed 2 of original foot of ladder become a stress surface, greatly strengthen the stability of folding ladder.
Simultaneously at this self-supporting folding ladder when not using, unclamp locking device 6, inwardly pull the second auxiliary support bar 3 simultaneously, make in alignment between the second auxiliary support bar 3 and the first auxiliary support bar 5 till, now be fixed by tightening locking device 6, can conveniently realize folding, be convenient to put at ordinary times and carry.
The self-supporting folding ladder structure that the utility model provides is simple, easy to use, break away when can effectively prevent folding ladder from using, and an independent people can use folding ladder, save manpower, safe and reliable, simultaneously self-supporting folding ladder of the present utility model can fold fast when not using, conveniently laying and carry.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in above-mentioned embodiment, also comprises the technical scheme be made up of above technical characteristic.
