Description
Technical field
The utility model belongs to daily necessities, particularly a kind of quick-folding bicycle.
Background technology
Folding bicycle of the prior art, its volume is big, the folding and expansion of inconvenience.
Summary of the invention
It is little that the purpose of this utility model provides a kind of volume, lightweight quick-folding bicycle.
The utility model is to realize by following technical scheme: the utility model comprises forearm, middle arm, postbrachium, forearm and middle arm are hinged with an articulated joint, middle arm and postbrachium are hinged with another articulated joint, the seat support link lower end is connected with Hooke's coupling respectively with connecting rod with connecting rod, connecting rod is connected with Hooke's coupling with postbrachium, and connecting rod is connected with Hooke's coupling with forearm; The cushions support bar is plugged in the conduit, and it can be slided in conduit, and during conduit is installed on the arm, but they have constituted the pentagon of a grade separation distortion, and the front of conduit 4 is provided with axis, is provided with Thrust nut below the strut bar.
The utility model also can be realized by following technical scheme: the utility model comprises forearm, middle arm, postbrachium, the shared articulated joint of forearm and middle arm postbrachium is hinged, the seat support link lower end is connected with Hooke's coupling respectively with connecting rod with connecting rod, connecting rod is connected with Hooke's coupling with postbrachium, and connecting rod is connected with Hooke's coupling with forearm; The cushions support bar is plugged in the conduit, and it can be slided in conduit, during conduit is installed in arm by rear end, but they have constituted the quadrangle of a grade separation distortion, the front of conduit is provided with axis, is provided with Thrust nut below the strut bar.
Described articulated joint is the lateral inclination joint, and it comprises female cover, son cover and screw rod, and the three is arranged in one successively, and female cover is installed on the arm, and another arm is provided with boss, wears wherein for screw rod.
During use, lift conduit, just can realize the folding of bicycle, it is just deployable to put down conduit.
Good effect of the present utility model is: simple in structure, fast folding, launch quicker, small and exquisite, convenient and practical.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further
Fig. 1 is the utility model first example structure figure
Fig. 2 is the utility model second example structure figure
Fig. 3 is a lateral inclination junction composition
Among the figure, 1 forearm, arm in 2,3 postbrachiums, 4 conduits, 5 seat support link, 6 Thrust nuts, 7 connecting rods, 8 connecting rods, 9 Hooke's couplings, 10 Hooke's couplings, 11 Hooke's couplings, 12 articulated joints, 13 articulated joints, 14 axis, 15 female covers, 16 son covers, 17 screw rods, 18 bosses.
The specific embodiment
As shown in Figure 1, the utility model comprises forearm 1, middle arm 2, postbrachium 3, forearm 1 is hinged with articulated joint 12 of middle arm 2 usefulness, middle arm 2 is hinged with another articulated joint 13 of postbrachium 3 usefulness, seat support link 5 lower ends are connected with Hooke's coupling 9 respectively with connecting rod 8 with connecting rod 7, connecting rod 8 is connected with postbrachium 3 usefulness Hooke's couplings 11, and connecting rod 7 is connected with forearm 1 usefulness Hooke's coupling 10; Seat support link 5 is plugged in the conduit 4, and it can be slided in conduit 4, and during conduit 4 is installed on the arm 2, but they have constituted the pentagon of a grade separation distortion, and the front of conduit 4 is provided with axis 14, is provided with Thrust nut 6 below the strut bar 5.
As shown in Figure 2, the utility model comprises forearm 1, middle arm 2, postbrachium 3, forearm 1 and middle arm 2, postbrachium 3 shared articulated joints 12 are hinged, seat support link 5 lower ends are connected with Hooke's coupling 9 respectively with connecting rod 8 with connecting rod 7, connecting rod 8 is connected with postbrachium 3 usefulness Hooke's couplings 11, and connecting rod 7 is connected with forearm 1 usefulness Hooke's coupling 10; Seat support link 5 is plugged in the conduit 4, and it can be slided in conduit 4, and during conduit 4 is installed on the arm 2, but they have constituted the quadrangle of a grade separation distortion, and the front of conduit 4 is provided with axis 14, is provided with Thrust nut 6 below the strut bar 5.
As shown in Figure 3, the lateral inclination joint comprises female cover 15, son cover 16 and screw rod 17, and the three is arranged in one successively, and female cover 15 is installed on the arm, and another arm is provided with boss 18, wears wherein for screw rod 17.
Shown in Fig. 1, Fig. 2, Hooke's coupling 9 is the two-in-one type Hooke's coupling, can be connected simultaneously with connecting rod 7,8.
Certainly, interface also can adopt other structures in main car frame: as other forms of interfaces such as rail mounteds, the Hooke's coupling at same connecting rod two ends can adopt other form, perhaps adopt steel wire tow line and rigid overcoat to form connecting rod and replace former connecting rod (7) (8), can save the Hooke's coupling at former connecting rod two ends like this.All above conversion all can reach the clover leaf distortion quadrangle or the pentagon vehicle frame of superimposed front and back wheel.Such conversion all drops within the protection domain of the present utility model.
