Description
Technical field
This utility model relates to folding product technical field, is specifically related to novel stay cord quick release fold mechanism。
Background technology
Bicycle, body-building apparatus etc. all can relate to fold mechanism, it is possible to folded up by product, it is simple to collection management and transport, especially folding bicycle, and general folded bicycle has vehicle frame folding joint and standpipe folding joint to constitute。By vehicle frame folding, by front and back two-wheeled doubling together, can reduce by the length of about 45%。Car load can put into boarding case and folding bag and the boot of automobile after folding。Also without by external tools in folding process, can manually by car folding and expanding。Pass through seat bar after folding as the strong point so that can stand steady after folding。Folding bicycle carries, easy to use comfortable, mature production technology。But the structure of the fold latch of these products existing is complicated, it is necessary to first opens safety lock, then strikes out handle with the hand, can fold, complicated operation, and make owing to being entirely metal, heavier-weight, cause that whole product seems heavy, be not easy to operation and transport, it would be highly desirable to improve。
Utility model content
The purpose of this utility model is in that the defect for prior art and deficiency, a kind of simple in construction, novel stay cord quick release fold mechanism reasonable in design, easy to use are provided, by unblock by pull rope mechanism and open a step and complete, save releasing process, and overall weight is lighter, greatly facilitating user to its collection management, Practical Performance is higher。
For achieving the above object, the technical solution adopted in the utility model is: it comprises upper boom, lower beam, folding rod main shaft, axle, quick-release handle, top pressure spring, No. two axles, jacking block, torsion spring, No. three axles；Upper boom is connected by folding rod main shaft with lower beam；The side, bottom of described upper boom is connected to quick-release handle by an axle, the inside of quick-release handle is connected to jacking block by No. two axles, top pressure spring and the mutual clamping of projection of the top of jacking block and lower beam upper end it is provided with between top briquetting on the side of jacking block and quick-release handle medial wall；It also comprises safe block, No. four axles, stay cords；The bottom of described jacking block is connected to safe block by No. three axles, and one end of safe block is provided with torsion spring, and the other end bottom of safe block is connected to stay cord by No. four axles；The described Ka Jiao in safe block and the mutual clamping of draw-in groove on quick-release handle sidewall；The sidewall of described quick-release handle is provided with solution fore shaft, and solution fore shaft is integral type structure with draw-in groove。
Operation principle of the present utility model is as follows: the Ka Jiao of safe block and the draw-in groove clamping on quick-release handle, and now, jacking block withstands the projection on lower beam, and overall in locking state, when not pulling stay cord, direct pull quick-release handle can not be opened；When needs unlock, pull stay cord, stay cord drives safe block to rotate around No. three axles, now the Ka Jiao in safe block enters and solves in fore shaft, and safe block unlocks, and jacking block loosens, pull on stay cord, can pull open quick-release handle, by unblock by stay cord and open quick-release handle one step and complete, eliminate the process of unblock。
After adopting said structure, this utility model has the beneficial effect that novel stay cord quick release fold mechanism described in the utility model, by unblock by pull rope mechanism and open a step and complete, save releasing process, and overall weight is lighter, greatly facilitating user to its collection management, Practical Performance is higher, and has simple in construction, arranges the advantages such as reasonable, cost of manufacture is low。
