Abstract
The utility model discloses a folding single ladder, including parallel left and right supporting beam and a plurality of horizontal poles, this horizontal pole includes left and right horizontal pole and the right -hand member of left horizontal pole is articulated with the left end of right horizontal pole, the left end of left side horizontal pole articulates respectively on left and right supporting beam with the right -hand member of right horizontal pole, left and right supporting beam all is provided with the dog respectively on the below position with the articulated department of left and right horizontal pole. The utility model discloses a with horizontal pole design for articulated left and right horizontal pole together, left and right horizontal pole is articulated with left and right supporting beam respectively again, realizes the folding form that left and right supporting beam can laminate and be in the same place, simple structure, it is also very convenient to use.
Description
Technical field
The utility model relates to a kind of single ladder, is 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.
Utility model content
For solving the deficiencies in the prior art, it is simple that the utility model provides structure, folding single ladder.
The utility model 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.
The beneficial effects of the utility model: traditional crossbar design is by the hinged structure of left and right cross bar by the utility model, 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 utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
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 utility model 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 utility model preferably embodiment, and it does not form the restriction to the utility model protection domain, as long as realize the purpose of this utility model with substantially identical means all should belong to protection domain of the present utility model.
