The specific embodiment

See also Fig. 1 to Fig. 4, the utility model is a kind of Breaststroke Sports Car, and it mainly is made up of a front fork stem 10, two back vehicle frames 20, two back wheels 30 and a brake group 40;

Be pivoted with a handle rack 11 that is the T type in this front fork stem 10, the below that this handle rack 11 is positioned at this front fork stem 10 guide front wheel 12 that can rotate with this handle rack 11 that is pivoted, and the outer peripheral edges of this front fork stem 10 set firmly one divergent 13, the middle position of this fork 13 sets firmly an anti-collision block 14, and should fork 13 opening both sides articulate with each back vehicle frame 20 respectively, and should fork 13 opening be positioned at the outside that each back vehicle frame 20 the articulates side pin 15 that is pivoted respectively, each side pin 15 and anti-collision block 14 limit the pivoting angle of each back vehicle frame 20 respectively, in present embodiment, each side pin 15 be the rubber material with being somebody's turn to do anti-collision block 14;

One end of each back vehicle frame 20 has an articulated section 21 respectively, each articulated section 21 is hubbed at respectively in this fork 13, each back vehicle frame 20 is pivoted, the end face of each back vehicle frame 20 sets firmly a pedal 22 respectively, and each back vehicle frame 20 is with respect to an end of each articulated section 21, form the bending segment 23 of a vertical configuration respectively, each bending segment 23 is provided with for each back wheels 30 respectively;

Each back wheels 30 is made up of a pivot seat 31, a back vent 32, a trailing wheel 33 and an extension spring 34 respectively;

Each pivot seat 31 is fixedly arranged on bending segment 23 outsides of each back vehicle frame 20 respectively, and each back vent 32 is pivoted respectively in each pivot seat 31, the top of each back vent 32 has a pivot pipe 321 respectively, each pivot pipe 321 is hubbed at respectively in each pivot seat 31, each trailing wheel 33 and bottom of each back vent 32 is pivoted respectively, and each back vent 32 has respectively with respect to a side of each trailing wheel 33 and colludes end 322, respectively collude end 322 and collude and establish for each extension spring 34 respectively, the free end of each extension spring 34 is fixedly arranged on bottom surface desired location of each back vehicle frame 20 respectively;

This brake group 40 by a brake cable 41, be fixedly arranged on the handle 42 on this handle rack 11, a L-shaped without exception brake facing 43 and an elastic parts 44 formed;

One end of this brake cable 41 combines with this handle 42, and holding in addition after sheathed this elastic parts 44 of this brake cable 41, combine with an end of this brake facing 43, this brake facing 43 is hubbed at back vent 32 desired locations of these back wheels 30, and utilize the pulling of brake cable 41, this brake facing 43 is pivoted, and this trailing wheel 33 stopped stop.

Combination by above each member, please cooperate and consult Fig. 2 to Fig. 6, when the user drives, utilize handle rack 11 to implement direction control, double-legged then be placed in two the back vehicle frames 20 pedal 22 on, simultaneously two back vehicle frames 20 are expanded outward with foot again and open, inwardly closing again, so perseveration forms a power, advance (as Fig. 5 and shown in Figure 6) and order about car body, and the user also can utilize handle 42 pulling brake cable 41, brake cable 41 interlock brake facings 43 are pivoted, and by brake facing 43 trailing wheel 33 folders are stopped, make it to stop operating.

Wherein, when back vehicle frame 20 outwards launches, wheels 30 behind the bending segment 23 meeting interlocks of back vehicle frame 20, make the back vent 32 of back wheels 30 be able to pivot for the center according to pivot pipe 321, and the end 322 that colludes of back vent 32 just spurs extension spring 34, make extension spring 34 be extended state, and after the strength on the pedal 22 of vehicle frame 20 disappears after the user puts on, because the elastic-restoring force of extension spring 34, make it back vent 32 is pulled back, and by outwards opening of so continuing, inwardly folding (as Fig. 5 and shown in Figure 6) not only can reach the application target that the driving car body advances, and also has shank, waist movement body-building, and then the use effect of lifting physiological function;

In addition, please continue to cooperate and consult Fig. 5 and Fig. 6, when the user drives the utility model, utilize back vehicle frame 20 to be expansion, the closing state, and back wheels 30 are inwardly produced, extrinsic deflection, and then order about car body and slide forward, and because fork of the present utility model 13 middle position set firmly the anti-collision block 14 of a rubber material, and divergent 13 opening is positioned at the outside that each back vehicle frame 20 articulates, the side pin 15 of the rubber material that is pivoted respectively, utilize the setting of two side pins 15 and anti-collision block 14, make it to be limited the pivoting angle of back vehicle frame 20, and the collision noise of avoiding effectively operating produces.
