Be parallel to fan-shaped circular arc line on the described quadrant and be respectively equipped with slotted hole and circular hole.
Described trailing wheel spindle nose is provided with spindle nose ladder piece.
Described upper beam axial shape is a S shape.
The beneficial effects of the utility model: but this structure at high speed changes the distance size of front and back wheel, laborsaving, quick, safety, convenience and practical.The good stability of riding after car body launches reaches the performance requriements of bicycle and Electrical Bicycle fully.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is contraction state figure of the present utility model.
The specific embodiment
As shown in the figure, a kind of trailing wheel rotary extension damping folding bicycle, comprise upper beam 2 with 1 welding of vehicle frame front tube, with the standpipe 5 of the end welding of putting the beams in place and back digonal link 8-1 and by chain stay 12 behind fork sheet 11 bonded assemblys, trailing wheel 13 and axle 11-2, described standpipe is divided into two parts up and down, its underpart is damping type bumper 22 and forms Vee formation with back digonal link and back chain stay, described back digonal link 8-1 front end both sides soldering angle contact pin 8 also is connected with Connection Block 6 bearing pins 7 that riser upper is divided, damping type bumper 22 upper ends are connected with angle contact pin 8 bearing pins 20, the back end of tie rod that retreads is connected with back chain stay fork sheet bearing pin 10, described back chain stay front end is provided with and the big little five-way adapter shaft 18 of five-way 9 bonded assemblys, described little five-way adapter shaft is connected with cylinder lever connecting rod 16 bearing pin 18-1, the cylinder lever connecting rod front end is connected by engaging lug 3 bearing pins 19 of quadrant 14 with the middle part of putting the beams in place, and described quadrant and engaging lug are provided with open and close type self-locking hand button 4.Described damping type bumper lower end connects by the attached moving pull bar 21 of bearing pin 15,17 pin joints at the cylinder lever connecting rod middle part.Be parallel to fan-shaped circular arc line on the described quadrant and be respectively equipped with slotted hole 14-2 and circular hole 14-1.Described trailing wheel spindle nose is provided with spindle nose ladder piece 11-1.Described upper beam axial shape is a S shape.See the described bearing pin the 7, the 19th of Fig. 1 for details, unmoving axle, bearing pin the 10, the 18th, moving axis, bearing pin the 15,17, the 20th, attached moving axis is the boundary with damping type bumper 22, triangle before bearing pin 7,18,19 forms, bearing pin 7,10,18 forms Vee formation; See Fig. 2 for details, shrink back two-wheel wheelspan and diminish, this moment, bearing pin 7,10,18 formed a big triangle, and 15,17,20 3 axles of attached moving axis moments becomes Fig. 2 position by Fig. 1 position simultaneously.Whole telescopic process is the rotation break fully with the axle center.Flexible control step: when bicycle is in the riding condition desire it is shunk, left hand is pulled out and is opened and closed self-locking hand button 4 (pull out length and be about 5 millimeters), it shifts out from the slotted hole 14-2 of quadrant, carry vehicle seat on the right hand is light, gently playing trailing wheel spindle nose ladder piece 11-1 forward with right crus of diaphragm, is the axle center with unmoving axle 7,19, and moving axis 10,18 drive car load rear lower positions are done rotation forward and moved, open and close self-locking hand button 4 and enter among the circular hole 14-1 of quadrant, finish the contraction self-locking action.Whole process was less than 1 second.When needing to launch, open and close self-locking hand button 4, gently play trailing wheel spindle nose ladder piece 11-1 backward, get final product with right crus of diaphragm as long as draw back once more.Whole process was less than 0.5 second.This structure is applicable to bicycle or Electrical Bicycle.
