As the further improvement of such scheme, this rotating shaft is positioned at the midway location of this housing, and this second pilot bar is positioned at the front end of this housing.
As the further improvement of such scheme, this housing side cross-section is oval.
A kind of carriage for children using described guiding and rolling structure, comprise handlebar, front vehicle wheel device, rear wheel device, pipe link, vehicle seat, this handlebar is connected with this front vehicle wheel device, this vehicle seat is fixed on this pipe link, the two ends of this pipe link are connected with this front vehicle wheel device and this rear wheel device respectively, it is characterized in that: this front vehicle wheel device comprises the first cross bar, first guiding and rolling structure and the second guiding and rolling structure, the two ends of this first cross bar offer the first through hole and the second through hole, this first guiding and rolling structure comprises the first pilot bar, this second guiding and rolling structure comprises the second pilot bar, this first through hole coordinates with this first pilot bar fit, this second through hole coordinates with this second pilot bar fit, and be installed with clutch shaft bearing between this first through hole and this first pilot bar, the second bearing is installed with between this second through hole and this second pilot bar.
As the further improvement of such scheme, the two ends of this first cross bar are bent into right angle respectively in the horizontal direction, this right-angled vertical upwards 30 °.Bending place is that the pin of children tramples place, when trampling this first cross bar, carriage for children can be made to move ahead.
The present invention is owing to being provided with the 5th bearing between pilot bar and housing, make can relatively rotate between pilot bar and housing, make pilot bar pull housing forward or right slightly to the left is moved time more convenient, and pilot bar pusher is obstructed when moving after making housing, effect of the present invention is that housing is moved forward, interrupted when then moving, and utilizes the carriage for children of this guiding and rolling structure, carriage for children can be made to moving ahead, can not can only to retreat.
Accompanying drawing explanation
The guiding and rolling structure front view that Fig. 1 provides for better embodiment of the present invention;
Fig. 2 is A-A portion view in Fig. 1;
Fig. 3 is the carriage for children using better embodiment of the present invention.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1 and Fig. 2, a kind of guiding and rolling structure, comprise the second pilot bar 24, housing 25, roller 26, rotating shaft 261, this rotating shaft 261 is fixed fit with this roller 26 and is coordinated, this housing 25 side cross-section ovalize, front end and rear end longer dimension, the relative position of these housing 25 two sides offers two corresponding circular holes, these two circular holes are provided with the 3rd corresponding bearing 251 and the 4th bearing 252, the two ends of this rotating shaft 261 are stretched out this roller 26 and are fixed on the 3rd corresponding bearing 251 and the 4th bearing 252, the latter half of this roller 26 is positioned at outside this housing 25, and roller 26 is positioned at the midway location of this housing 25, roller 26 can also move by support housing 25, the front end of the upper surface of this housing 25 offers guide apertures, this guide apertures internal fixtion is sheathed with the 5th bearing, this second pilot bar 24 is fixed on the 5th bearing, housing 25 and the second pilot bar 24 can be relatively rotated.
When pilot bar 24 is to front haulage, housing 25 can dead ahead or right slightly to the left advance, and when the second pilot bar 24 is to rear haulage, housing 25 is drawn back by resistance, can not be shifted.
With reference to Fig. 3, a kind of carriage for children using described guiding and rolling structure, comprise handlebar 1, front vehicle wheel device 2, rear wheel device 3, pipe link 4, vehicle seat 5, this handlebar 1 is connected with this front vehicle wheel device 2, this vehicle seat 5 is fixed on this pipe link 4, the two ends of this pipe link 4 are connected with this front vehicle wheel device 2 and this rear wheel device 3 respectively, this front vehicle wheel device 2 comprises the first cross bar 21, first guiding and rolling structure and the second guiding and rolling structure, this first guiding and rolling structure comprises the first pilot bar, this second guiding and rolling structure comprises the second pilot bar 24, the two ends of this first cross bar offer the first through hole 22 and the second through hole 23, this first through hole 22 coordinates with the first pilot bar fit, this second through hole 23 coordinates with the second pilot bar 24 fit, and be installed with clutch shaft bearing between this first through hole 22 and first pilot bar, the second bearing is installed with between second through hole 23 and the second pilot bar 24.
