Specific embodiment
Make specific further instruction to the utility model below in conjunction with the accompanying drawings.A kind of folding child's tricycle,
Including main support 1 and be hinged on the front fork 2 of its front end, front-wheel 21 be installed on front fork 2, and by turn to 22 drive front forks 2 and
21 left and right turn of front-wheel, it is characterised in that：1 tail end of main support is hingedly equipped with left socle 4 and right branch by hinged seat 3
Frame 5, left socle 4 and 5 tail end of right support are separately installed with left rear wheel 41 and off hind wheel 51；
The wherein described hinged seat 3 includes the articulated shaft 31 being located on main support 1 and on left socle 4 and right support 5
Hinged set 32, hinged set 32 and articulated shaft 31 make coaxial cooperation so that left socle 4 and right support 5 can be 31 turns with respect to articulated shaft
It is dynamic, positioning plate 6 is additionally provided on the left socle 4 and right support 5, it is fixed that first positioning hole 61 and second is provided on positioning plate 6
Position hole 62, is connected by guide groove 63 between two location holes, lock pin 33 is provided in hinged seat 3, it is fixed that lock pin 33 is inserted into first
In 61 or second location hole 62 of position, the positioning action to left and right stent is played；
The lock pin 33 telescopic up and down can be mounted in hinged seat 3, and drive its up and down motion, institute by spanner 34
Avoiding hollow groove 35 is provided on the cylinder of lock pin 33 stated, after avoiding hollow groove 35 is aligned with guide groove 63, left and right stent 4,5
Adjustment three-wheel car state is swung with opposite hinged seat 3.
35 diameter of avoiding hollow groove is more than 63 width of guide groove so that lock pin 33 can enter first by guide groove 63
In 61 and second location hole 62 of location hole.
Rack positioning hole 36 is provided on the articulated shaft 31, the stent positioning pin 37 on left and right stent 4,5 is inserted
Enter in the rack positioning hole 36, play the positioning action to left and right stent 4,5.
Operation principle：As described in Fig. 1,2, when the perambulator in this case as toy tricycle in use, left and right two stands are outside
It opens, left and right two trailing wheel outwardly opens.Meanwhile lock pin is inserted into the second location hole being located on positioning plate.Positioned at left and right
Stent positioning pin on stent is inserted into the rack positioning hole being located on articulated shaft.Therefore, left and right stent and the phase between hinged seat
Adjusting the distance can jointly be locked by lock pin and stent positioning pin, ensure that children will not occur in ride loosen or
Deformation.
As shown in figure 9, when perambulator is in two-wheeled use state in this case, trailing wheel lock pin is first unclamped so that rear wheel lock
Shotpin is detached from out of trailing wheel locking hole, and two trailing wheels are able to inwardly overturn 90 ° by turnbarrel so that the outer surface of two trailing wheels
Opposite installation.Then trailing wheel lock pin is inserted into trailing wheel locking hole, and locking trailing wheel is in varus state.Then release stent positioning
Pin, makes it be detached from out of rack positioning hole on articulated shaft.Finally press down on spanner, spanner driving lock pin move downward,
So that after the avoiding hollow groove on lock pin cylinder is aligned with the guide groove on positioning plate, left and right stent is able to opposite hinged seat pendulum
It is dynamic so that left and right stent can be folded inward in two-wheeled state.After the completion of folding, spanner is unclamped, lock pin resets so that lock
Avoiding hollow groove on shotpin misplaces with guide groove, and lock pin is inserted into first positioning hole, locks the relative position of left and right stent, this
When perambulator then used as two-wheeled cycle.
Compared with traditional technology, the perambulator in this case can switch over use between three-wheel and two-wheeled function so that
Parent need to only buy a vehicle, multi-functional to meet use needs of the children to three-wheel and two-wheeled cycle and balance car,
First parent's economic pressures are reduced, second avoid family that the vehicle for buying more different function is needed to need a large amount of place storages.Together
When, when toy tricycle is folded in two-wheeled pattern, its floor space can be effectively reduced, stores, therefore can be pushed away extensively convenient for user
It is wide to use.
The basic principle of the utility model and main feature and the advantages of the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
