Abstract
The invention discloses a foldable single ladder, which comprises left and right support beams which are in parallel and multiple cross bars, wherein each cross bar comprises left and right cross bars, the right end of each left cross bar is hinged with the left end of each right cross bar, the left end of each left cross bar and the right end of each right cross bar are respectively hinged on the left and right support beams, and the left and right support beams are both provided with check blocks at the positions below the hinged parts of the left and right support beams and the left and right cross bars. According to the foldable single ladder disclosed by the invention, the cross bars are designed to left and right cross bars which are hinged together, and the left and right cross bars are respectively hinged with the left and right support beams, thus realizing the purpose that the left and right support beams can be folded in an attached mode. The structure is simple and the use is very convenient.
Description
Technical field
The present invention relates to a kind of single ladder, be specifically related to a kind of folding single ladder.
Background technology
Single ladder has and uses widely in the work and daily life of people.Simple single ladder is generally made up of two, left and right brace summer and the horizontal some crossbeams be fixed between these two brace summers, and the terraced structure of this list is simple, but it is comparatively large to take up room, inconvenience collection.Also have now telescopic single ladder, mainly brace summer is designed to Collapsible structure, when packing up, volume reduces greatly, but this project organization is complicated, comparatively bothers when opening, and cost is also higher.
Summary of the invention
For solving the deficiencies in the prior art, the invention provides structure simple, folding single ladder.
The present invention deal with problems adopt technical scheme be:
A kind of folding single ladder, comprise parallel left and right brace summer and some cross bars, this cross bar comprises left and right cross bar and the left end of the right-hand member of left cross bar and right cross bar is hinged, the left end of described left cross bar and the right-hand member of right cross bar are hinged on left and right brace summer respectively, described left and right brace summer respectively with the lower position of left and right cross bar hinged place on be provided with block.
As the further improvement of such scheme, also comprise a connecting rod, described connecting rod and each root are positioned at the left cross bar in outside or right cross bar is hinged and this connecting rod is parallel to left and right brace summer.
As the further improvement of such scheme, left and right brace summer and left and right cross bar are stainless steel or aluminium alloy element.
Beneficial effect of the present invention: traditional crossbar design is by the hinged structure of left and right cross bar by the present invention, left and right brace summer is pulled about during use, left and right cross bar is just on general same straight line along with turning to and is blocked by block, now just can go up ladder; Ladder can be inverted when packing up, left and right promotes left and right brace summer and collapsible laminating, and structure is simple, uses also more convenient.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Clear, complete description is carried out, to understand object, the characteristic sum effect of the invention fully below with reference to embodiment and the accompanying drawing technique effect to the design of innovation and creation, concrete structure and generation.Each technical characteristic in the invention, can combination of interactions under the prerequisite of not conflicting conflict.
With reference to Fig. 1, a kind of folding single ladder, comprise parallel left and right brace summer 1,2 and some cross bars 3, this cross bar 3 comprises left and right cross bar 31,32 and the left end of the right-hand member of left cross bar 31 and right cross bar 32 is hinged, the left end of described left cross bar 31 and the right-hand member of right cross bar 32 are hinged on left and right brace summer 1,2 respectively, described left and right brace summer 1,2 respectively with the lower position of left and right cross bar 31,32 hinged place on be provided with block 4.
Further to embodiment, also comprise a connecting rod 5, described connecting rod 5 and each root are positioned at the left cross bar 31 in outside or right cross bar 32 is hinged and this connecting rod 5 is parallel to left and right brace summer 1,2.This connecting rod 5 being set, when packing up ladder, with hand propelled connecting rod 5, left and right cross bar 31,32 all upwards being turned an angle, in the i.e. collapsible laminating of the left and right brace summer 1,2 of promotion, do not need ladder to be inverted.In addition, the left and right brace summer 1,2 of the present embodiment and left and right cross bar 31,32 are stainless steel or aluminium alloy element.
The present invention is by being designed to hinged left and right cross bar 31,32 by cross bar 3, left and right cross bar 31,32 more respectively with left and right brace summer 1,2 hinged, realize the folded form that left and right brace summer 1,2 can fit together, structure is simple, uses also very convenient.
The above is the present invention's preferably embodiment, and it does not form limiting the scope of the invention, as long as realize object of the present invention with substantially identical means all should belong to protection scope of the present invention.
