Description
Technical field
The utility model is related to a kind of ascending tool, especially a kind of stable high-strength good using steady, bearing capacity
The wide pedal of aluminium alloy folds double ladder.
Background technology
Double ladder is folded as a kind of ascending tool, including preceding ladder, rear ladder, top plate, pedal, preceding ladder and rear ladder
On component be mostly individually fixed on preceding ladder and rear ladder, then front and back ladder is hinged by rivet afterwards.
Existing folding double ladder has the following problems in use：First, front and back ladder is mutually related component by
It is smaller in the torque for bearing lateral, therefore ladder will produce rock when in use, stability is poor, and security performance is bad.Second is that folding
For folded double ladder other than top plate is using larger area, remaining all uses relatively narrow pedal or riding club, such consumer using
In the process, in addition to position relative comfort of the station in highest top plate, have when stepping down on other pedals it is a kind of with foot contact area compared with
Uncomfortable feeling is generated less, but in actual use, due to the uncertainty of working depth, all per level-one pedal
Possible as groundwork height.Third, folding the plastic components that is contacted with ground of double ladder or by using soft material
Mass-energy keeps the frictional force of ladder and ground, but because the material is soft, and abjection is easy after assembly and is fallen；By using harder
Material ensures fixation, and when achieving the purpose that be not easy abjection, but using and the frictional force on ground is less, and ladder is easy to slide
It convinces by patient analysis and ladder security performance is caused to decline.
To solve the above-mentioned problems, many manufacturers and knowledgeable people have carried out R and D, but so far there has been no
Comparatively ideal product emerges.
Invention content
To overcome the above problem existing for existing Foldable '*' shape ladder, the purpose of this utility model to be to provide a kind of structure letter
List is reasonable, easy for operation, be connected firmly, stability is good, it is small, safe and reliable to rock, bearing capacity is good high intensity
The wide pedal of aluminium alloy folds double ladder.
The utility model solves technical solution used by its technical problem, it includes preceding ladder, rear ladder, top plate, steps on
Plate, before the rear ladder is hinged on ladder, before pedal is uniformly fixed on ladder, the preceding ladder of ladder before top plate is hinged on
Top on crossbeam and positioned at top plate, the other side of top plate are equipped with the bayonet with the rear ladder beam engagement of rear ladder, rear ladder
Rear ladder crossbeam on be arranged with rotatable left and right aluminium alloy lantern ring, correspondence is fixed with aluminium alloy U on the aluminium alloy lantern ring of left and right
The bar supported on both sides correspondence of type holder, aluminium alloy u-bracket is hinged on the frame of top plate both sides, and aluminium alloy u-bracket is main
Effect is to push top plate automatic turning when increasing the sideway torque being connected with each other between front and back ladder and folding.
The further scheme of the utility model connects the company of restricted ladder aperture between the preceding ladder and rear ladder
Connect drawstring.
The further scheme of the utility model, it is fixed between the rear ladder crossbeam of the rear ladder and corresponding rear ladder
There is inclined support bar.
The further scheme of the utility model, the pedal are correspondingly provided with before on pedal by aluminium alloy extruded molding
The fixed front and back riser of ladder riveting, the both sides of pedal are correspondingly provided with the card slot being buckled on preceding ladder, are correspondingly provided on pedal
When folding with the matched folding notch of rear ladder.
The further scheme of the utility model, the bottom of the front and back ladder, which corresponds to, is fixed with footmuff, the footmuff by
Ebonite covers and soft rubber cushion quadric injection mould forms, and the indent bottom of ebonite set is equipped with convex ribs, and soft rubber cushion is correspondingly arranged at ebonite set
Indent bottom is simultaneously equipped with the groove coordinated with convex ribs, and the bottom surface of soft rubber cushion is equipped with anti-slop serrations.

Side, which corresponds to, is fixed with pedal end cap, and pedal end cap passes through on ladder before corresponding be buckled in.
With the above structure, it has the advantage that compared with the prior art and effect：When improve top plate and rear ladder it
Between connection structure, be arranged with rotatable left and right aluminium alloy lantern ring, left and right aluminium alloy lantern ring on the rear ladder crossbeam of rear ladder
Upper correspondence is fixed with aluminium alloy u-bracket, and the bar supported on both sides of aluminium alloy u-bracket corresponds to the frame for being hinged on top plate both sides
On, aluminium alloy u-bracket not only increases the sideway torque being connected with each other between front and back ladder, rocks and compares when using ladder
It is small, stability is substantially increased, and simplify the foldable structure of top plate, the two of aluminium alloy u-bracket is collateral when ladder folds
Strut pushes top plate to be flipped up, simple light.Second is that since pedal is by aluminium alloy extruded molding, it is correspondingly provided on pedal with before
The fixed front and back riser of ladder riveting, the both sides of pedal are correspondingly provided with the card slot being buckled on preceding ladder, are correspondingly provided on pedal
Pedal rigidity is substantially increased, pedal can be greatly improved with the matched folding notch of rear ladder, front and back riser when folding
Bearing capacity, while the width of pedal can be further increased, upper and lower pedal or the center of gravity more easily control when working on pedal
System is stood more steady.Third, being formed with soft rubber cushion quadric injection mould since footmuff is covered by ebonite, not only installation is simple, connects admittedly
It is fixed convenient, and when landing work, the anti-slop serrations of soft rubber cushion are contacted with ground, and frictional force is big, and non-skid property is good, further increases
Stability when ladder having been added to use.
