Description
Technical field
The present invention relates to a kind of accordion structure body, espespecially a kind of quick, convenient transmit device of fixing and folding rear strong fix that engages of various frame structures works that offers.
Background technique
Current many accordion structure bodies, such as fordable bicycle frame, Foldable ladder, folding desk/chair, foldable sport equipment, collapsible light fixture, folding bed, folding sunshade/awning, folding handle, folding foot rest, foldable type connecting rod ... Deng, its folding frame structure is the desirable quick pivotable fixing device of shortcoming mostly, therefore its all cannot with identical mechanism arrangement by accordion structure body engage rapidly fixing, unclamp or the folding described structure of pivotable, make the structure after folding cannot be completely fixed and prevent from becoming flexible.
For instance, at present folding bike mostly have that volume after folding thickness is excessive, the loose shortcoming such as cannot fix of folding rear carriage, folding of general its vehicle frame of folding bike, mainly that burst at vehicle frame arranges a coupling, rely on engagement characteristics that described coupling can removal skeleton and convenient that car body is folding, also rely on described coupling body framing can be re-engaged location for.
Because coupling is the folding key mechanism of bicycle, therefore it must consider structural Security, operational convenience, the conditions such as volume miniaturization and lightweight quantification, but existing vehicle frame coupling, often cannot take into account terms and conditions, its volume, width, weight is not too large, in operation, need exactly instrument auxiliary, or during operating cost, effort, complex steps, tearing in addition vehicle support body after folding open cannot effectively apply existing coupling mechanism and directly fixed, cause that car body is loose cannot facility be carried, this is a great shortcoming, therefore it is good how to develop a kind of Security, volume is little, width is little, lightweight, easy and simple to handle, the quick pivotable fixing device of accordion structure body that can be simultaneously effectively fixing after quick and support body is folding, it is the emphasis direction that dealer makes great efforts research and development at present.
Lift again an example, existing many Foldable ladders, its support body pivotable fixing device also has launches rear bond strength deficiency, the shortcoming such as after pivotable is folding, cannot effectively fix, the quick pivotable fixing device of a kind of accordion structure body newly developed is applied to Foldable ladder, making its operation easier, safe, quick, is also the emphasis that dealer makes great efforts research and development.
Summary of the invention
