Abstract

The utility model discloses a reinforced mechanism of a folding joint of a single beam folding bicycle, which mainly solves the problem of bad stiffness of the existing single beam folding bicycles. A reinforced mechanism of a folding joint of a single beam folding bicycle of the utility model is provided with a reinforced rod capable of participating in folding between a bicycle beam and a vertical tube, when the bicycle is in an unfolded state, the vertical tube, the bicycle beam, and the reinforced rod together constitute a triangle, and a folding joint is positioned on the bicycle beam of the triangle. Because the reinforced rod is additionally arranged between the bicycle beam and the vertical tube, and the reinforced rod can bear a part of stress to reduce the stress of the bicycle beam, so as to reduce the stress of the folding joint and strengthen the stiffness of a single beam folding bicycle.

Description

The reinforcing mechanisms of single-beam folding bicycle folding joint

The utility model relates to the reinforcing mechanisms of single-beam folding bicycle folding joint.

Folding joint is equipped with at the car beam middle part of folding bicycle, and the car beam can be 180 ° of folding joint place doublings.Folding bicycle has the branch of single-beam car and dual-beam vehicle, on two beams of dual-beam vehicle folding joint is arranged all, when bicycle was in deployed condition, the intensity of car load, rigidity all can guarantee, but the turning cylinder of the folding joint of two beams must overlap fully, accuracy of manufacture is required high.In addition, the user will operate two joints when folding or expansion bicycle, use trouble.The single-beam folding car structure is simple, and is easy to use, but advances at cycling, and folding joint has born big stress, even adopt tubing thick, that tube wall is thicker to make the car beam, still gives the not good enough sensation of a kind of rigidity of people.

The purpose of this utility model is the reinforcing mechanisms that provides a kind of single-beam folding bicycle folding joint, so that the rigidity of single-beam folding bicycle is further strengthened.

The reinforcing mechanisms of single-beam folding bicycle folding joint described in the utility model, the Che Liang two ends that folding joint is equipped with in the centre are connected with the standpipe that handlebar is housed with the standpipe that vehicle seat is housed respectively, between car beam and standpipe, be equipped with one and can participate in folding stirrup, when bicycle is in deployed condition, standpipe, car beam and stirrup constitute triangle jointly, and folding joint is on the interior car beam of triangle.

The reinforcing mechanisms of single-beam folding bicycle folding joint described in the utility model, between car beam and standpipe, increased a stirrup, car beam, standpipe and stirrup have constituted a stable triangle jointly, the single-beam folding bicycle is in the process of riding, but stirrup bearing part stress, subtract the stressed of craneway, thereby reduced the stressed of folding joint, further guaranteed the intensity of single-beam folded bicycle folding joint, strengthen the rigidity of single-beam folded bicycle, kept easy to operate advantage of folding joint of single-beam folded bicycle simultaneously again.

The unfolding state figure of a kind of described single-beam folding bicycle folding joint reinforcing mechanisms of Fig. 1;

Fig. 2 is the folded state diagram of Fig. 1;

The unfolding state figure of a kind of described single-beam folding bicycle folding joint reinforcing mechanisms of Fig. 3

The unfolding state figure of a kind of described single-beam folding bicycle folding joint reinforcing mechanisms of Fig. 4;

Embodiment 1 is as Fig. 1,2

The car beam 18 that folding joint 2 is equipped with in the centre also is connected with standpipe 19 axes intersect that vehicle seat is housed, be equipped with at

car beam

18 and 19 of standpipes and can participate in folding stirrup 1, stirrup 1, standpipe 19 and car beam 18 common formation triangles, and folding joint 2 is positioned at triangle; Stirrup 1 is divided into two sections, and two sections stirrups 5,6 are separately fixed on standpipe 19 and the car beam 18, and the free-ended end face of stirrup 5,6 is respectively the concave station 3 and the boss 4 that can coincide mutually.Its free-ended concavo-convex aligned to coincide and is as the criterion when the fixed angle of two sections stirrups 5,6 and car beam 18 and standpipe 19 was in deployed condition with car beam 18; Stirrup 2 is in car beam 18 tops, and two sections stirrups 5,6 are stressed and push against mutually, but bearing part stress, thus reduced the stressed of car beam 18.The stirrup 1 of this mechanism does not influence the folding of car beam 18.

Embodiment 2 is as Fig. 3

Stirrup 1 is hinged on the car beam 18, and the other end of stirrup 1 has draw-in groove 20, fixes the pin 23 of a protrusion on the vehicle seat standpipe 19, when bicycle was in deployed condition, the draw-in groove 20 of stirrup 1 can hang on the pin 23, made car beam 18, standpipe 19 and 1 of stirrup constitute triangle; During folding bicycle, stirrup 1 is withdrawed from from pin 23, be listed on the car beam 18, also do not influence the folding of car beam; All the other are identical with embodiment 1.

Embodiment 3 is as Fig. 4

Permanent seat 14 is housed on the car beam 18, stirrup 1 is divided into two sections, wherein one section stirrup 15 is captiveed joint with the five-way pipe 20 on the standpipe 19, and an end of another section stirrup 16 passes permanent seat 14 and is threaded with setting nut 17, and 15,16 mutual ring fastening types of two sections stirrups connect; When bicycle was in deployed condition, stirrup 1, car beam 18 and standpipe 19 constituted a triangle, and stirrup 1 is positioned under the car beam 18, adjust setting nut 17, strain the latch closure between two sections stirrups 15,16, stirrup 1 bearing part tensile stress, thus reduced the stressed of car beam 18; During bicycle folding, the connecting with latch closure of two sections stirrups 15,16, stirrup 1 is flexible, does not influence the folding of car beam 18; All the other are identical with embodiment 1;
