Double-right-angle type folding box

Abstract

The invention discloses a double-right-angle type folding box which comprises a first main body, a first bridge seat, a movable block, a second main body, a first rotating shaft component, a second rotating shaft component, an elastic plug pin mechanism and a safety device. The first bridge seat is slidably connected to the interior of the first main body, the first rotating shaft component is slidably mounted on the inner side of the first bridge seat, one end of the movable block is rotatably connected to the first rotating shaft component, and the second rotating shaft component is arranged on the inner side of the second main body and movably assembled in the movable block; the elastic plug pin mechanism is arranged in the movable block in a sliding mode and located between the first rotating shaft component and the second rotating shaft component. And the elastic bolt mechanism can be inserted into the first rotating shaft component under the pushing and pressing of the second rotating shaft component during contraction and pressing. A multi-section type double-right-angle folding structure is adopted, a vehicle can be completely folded by 180 degrees without interference, the folded vehicle is more regular and stable, and the internal strength is higher and more stable during normal use.

Description

technical field [0001] The invention relates to the technical field of folding devices for folding vehicles, in particular to a double right-angle folding box. Background technique [0002] At present, in the existing folding bicycle industry, the folding function of the folding bicycle is generally realized through the middle folding device, which is called a folding box in the art, and most of the folding boxes are folded in half, and the folding The front and rear ends of the folding box are respectively fixedly mounted on the front part and the rear part of the frame. [0003] The existing folding box has a single folding method, which is only folded in half. The single-hinge folding box used cannot completely fold the car 180 degrees. Therefore, the car is irregular, unstable and easy to shake after being folded, which leads to inconvenient storage and takes up space. , and even accidentally damage the bike. At the same time, compared with ordinary non-folding bicycle...

AI Technical Summary

Problems solved by technology

[0003] The existing folding box has a single folding method, which is only folded in half. The single-hinge folding box used cannot completely fold the car at 180 degrees. Therefore, the car is irregular, unstable and easy to shake after folding, which makes it inconvenient to store and takes up space. , or even accidentally damage the bike

At the same time, compared with ordinary non-folding bicycles, the folding parts are easy to break, loosen and have low fatigue resistance strength, resulting in insufficient strength of the segmented frame, which is not conducive to the stability and service life of the folding bicycle
