Detailed description of the invention
Below in conjunction with accompanying drawing, concrete further instruction is done to the present invention.A kind of toy tricycle, it comprises vehicle frame 1, and the saddle 2 be arranged on vehicle frame, push rod 3, trailing wheel 4, it is characterized in that: described vehicle frame 1 front end is provided with sleeve 5, in this sleeve, activity is articulated with front fork 6 and steering handle 7, the inverting seat 8 be fixedly connected with steering handle 7 is also provided with in described sleeve 5, the rotating shaft 61 on described front fork 6 top interts in the inside of inverting seat 8, front fork 6 is provided with the locating dowel pin 9 of the upper and lower slipping motion of energy, inverting seat 8 is provided with and the knock hole 81 of detent fit and the first position-limited trough 82.Pulling locating dowel pin can make it insert respectively in knock hole or the first position-limited trough, realizes being separated or combination of inverting seat and front fork; A pair elastic claw 84 that described inverting seat 8 comprises dowel disc 83 and is arranged on above dowel disc, described knock hole 81 and the first position-limited trough 82 are arranged on dowel disc 83; Described elastic claw 84 inside is provided with positioning boss 85, and positioning boss 85 is buckled in second position-limited trough 62 on rotating shaft 61 top, and the column 71 of described steering handle 7 is enclosed within elastic claw 84 periphery and is fixedly connected with inverting seat 8.
Described front fork 6 is provided with the chute 63 installing locating dowel pin 9, and locating dowel pin 9 is provided with the spanner 64 of outstanding detent surface.
Described knock hole 81 is can manhole close-fitting with locating dowel pin 9, and the first described position-limited trough 82 is circular arc kidney slot.Kidney slot has certain width, so locating dowel pin can be movable in the length range of kidney slot, realizes the steering angle restriction of front fork.
Described knock hole 81 and the first position-limited trough 82 are positioned at circumferentially same.
Described front fork 6 bend forward is extended.
Principle of work: during installation, first the rotating shaft of front fork is interted in inverting seat, be provided with positioning boss 85 in elastic claw 84 inside and be buckled in second position-limited trough 62 on rotating shaft top, therefore under the effect of rotating shaft, front fork can freely rotate in inverting seat, and can not come off in inverting seat.Then inverting seat is fit in the sleeve of vehicle frame front end, and the column 71 of steering handle 7 is enclosed within elastic claw 84 periphery be fixedly connected with inverting seat 8.Column 71 clip is peripheral at elastic claw, and can prevent elastic claw from outwards opening and being separated with front fork rotating shaft, now swing handle just can drive inverting seat to rotate in vehicle frame sleeve.When user selects children's master mode, pull spanner 64 and make locating dowel pin upward movement, in the knock hole 81 interted in inverting seat, because the aperture of knock hole 81 and locating dowel pin diameter closely cooperate mutually, now inverting seat and front fork can be fixedly connected as an entirety, rotating steering handle will certainly drive front fork to rotate by inverting seat, realize handle controlling party to object, now turning to of perambulator can only be controlled by handlebar, and the push rod being positioned at saddle rear can only play the object promoting perambulator and advance.
When user selects householder mode, pull spanner 64, locating dowel pin and knock hole are departed from, and front fork is now in universal pattern free to rotate, because inverting seat and front fork do not lock, so it can freely rotate relative to each other.If now need to turn to, the head of a family only needs, by pulling push rod 3, to make headstock generation beat, and under bending front fork effect, front-wheel 10 can deflect towards corresponding direction, realizes the order ground that the head of a family controls to turn to.At this moment children's swing handle can only drive inverting seat to rotate, and can not front fork be driven again to rotate.Even if so when head of a family's direction of operating, just front-wheel direction changes, and handle-bar then can not be turned by band, and therefore children still can rotate freely commutation handle, makes it keep certain recreational.Wherein in order to prevent, front-drive amplitude is too large produces potential safety hazard to children foot, can the second position-limited trough 62 be set on inverting seat 8, when user selects householder mode, front fork can be rotated 180 degree, the path of motion of the second position-limited trough 62 be overlapped with locating dowel pin, then upwards pulls locating dowel pin, locating dowel pin is made to intert in the second position-limited trough 62, now under the effect of the second position-limited trough 62, front-wheel can only or 45 degree of rotations to the right, prevent front-wheel dangerous because turning the larger generation of width left.Wherein it should be noted that, when switching to householder mode, namely front fork becomes bending backward and extends, the sleeve shaft core position of vehicle frame front end is more forward than the axle center of front-wheel 10, and therefore the head of a family is when beat push rod turns to, along with the beat direction of vehicle frame sleeve, first front-wheel 10 rotates to this direction, when user's driven forward, under the directional tagging of sleeve, pull traction front-wheel follow rotation, thus realize turning to and forward motion object.In operation steering procedure, due to complicated wire digging line system drive front-wheel steering need not be passed through again, so the steering operation process of the head of a family is lighter, eliminate the steering track rod system of conventional stroller complexity, the structure of this perambulator is more simple, compact, therefore can reduce productive costs, improve the market competitiveness.
In addition, in the present invention, child resistant pattern and head of a family's operation mode can be realized, and two kinds of pattern perambulators can only perform wherein a kind of, avoid traditional toy tricycle and child resistant and the head of a family easily occur operate and clash, even cause the drawbacks such as children injury.While same realization turns to object, the present invention operates more convenient, light and handy, reliable, therefore can extensively promote the use of.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to embodiment.For those of ordinary skill in the field, other multi-form change or change can also be made on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of extending out or change still be in claims of the invention protection domain among.
