Abstract

La présente invention concerne une structure de liaison de guidon. La structure de liaison de guidon comprend un guidon, une fourche avant et un jeu de direction ; une ouverture de liaison est formée sur le guidon ; la fourche avant comprend un tuyau de liaison situé au niveau d'une extrémité supérieure et utilisé pour être inséré dans l'ouverture de liaison ; la section transversale du tuyau de liaison et la section transversale de l'ouverture de liaison ont toutes deux une structure polygonale et sont adaptées l'une à l'autre ; une ouverture d'extension est formée au niveau de l'extrémité supérieure de la paroi de tuyau du tuyau de liaison dans une direction axiale ; et le jeu de direction est agencé dans une cavité de tuyau du tuyau de liaison. Selon la structure de liaison de guidon, la section transversale de l'ouverture de liaison du guidon et la section transversale d'un tuyau de liaison de fourche avant utilisé pour être inséré dans l'ouverture de liaison ont toutes deux la structure polygonale et sont adaptées l'une à l'autre, de telle sorte que le tuyau de liaison ne peut pas tourner dans l'ouverture de liaison ; de plus, le jeu de direction est agencé de manière rotative dans le tuyau de liaison, le diamètre externe du jeu de direction est augmenté de façon à pousser la paroi de tuyau du tuyau de liaison pour qu'elle s'étende vers l'extérieur, et la paroi externe du tuyau de liaison étendu est fermement fixée à la paroi interne de l'ouverture de liaison du guidon, de telle sorte que le tuyau de liaison et l'ouverture de liaison sont reliés de manière fixe et stable, permettant ainsi d'empêcher le guidon et la fourche avant de dévier dans une direction circonférentielle, et de garantir la précision de direction du guidon.
