Detailed description of the invention
With specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings, is not that practical range of the present utility model is confined to this.
As shown in Figures 1 to 5, a kind of wheel described in the present embodiment, include wheel rim c1 and for the foot step on device driving wheel rim c1 to rotate；Also include and prevent foot step on device from following the clutch that wheel rotates in the case of foot step on device does not uses.Passing through clutch so that after this wheel uses on perambulator, when the head of a family carries out or other non-feet step on operation, pedal c3 energy is unsettled and does not rotates with wheel；It is effectively prevented wheel running speed too fast again or dynamics is excessive, the problem that the tender bound feet bifurcation of child is caused damage.
Concrete, such as Fig. 5, a kind of wheel described in the present embodiment, described foot step on device includes pedal c3 and bent axle c4；Bent axle c4 be on the type pushchair frequently with S-shaped bent axle c4；Pedal c3 is two, is respectively arranged on the two ends of bent axle c4；Described clutch, include the driving shell c5 being connected with wheel rim c1 and being coaxially disposed and one group of expansion block c8, described driving shell c5 side is provided with a circle periphery c6, peripheral c6 inwall is provided with pit c61, each expansion block c8 one end all with drive shell c5 pivot joint, one lateral surface of expansion block c8 is provided with the convex stupefied c81 coordinated with pit c61, is linked together by a Flexible Connector between the other end of two expansion block c8；Each expansion block c8 medial surface is equipped with a clutch chamber c82；Bent axle c4 is provided with for enabling convex stupefied c81 card to set the horizontal block c7 to pit c61；Horizontal block c7 is located in the c82 of clutch chamber, and the other end of two expansion block c8 is equipped with for making expansion block c8 follow the salient point c83 that horizontal block c7 rotates.Its principle is as follows: when child steps on the pedal c3 of foot step on device, and horizontal block c7 rotates in the c82 of clutch chamber along with bent axle c4, due to the rotation of horizontal block c7 so that convex stupefied c81 can block and sets to pit c61；When being rotated further to certain angle, horizontal block c7 and salient point c83 against, now, child is further continued for stepping on pedal c3 when travelling forward, and wheel also will move along with the motion of pedal c3；When child does not step on pedal c3, when the head of a family pushes away perambulator later, owing to pedal c3 does not has rotatory force forward, expansion block c8 can shrink opening due to the effect that Flexible Connector connects, so that convex stupefied c81 departs from pit c61；The rotation of wheel will not drive driving shell c5, thus bent axle c4 and pedal c3 the most no longer follows vehicle wheel rotation, protects the tender bound feet bifurcation of child.
A kind of wheel described in the present embodiment, described horizontal block c7 includes the Fixed Division c71 affixed with bent axle c4 and keeps out arm c72 from what c71 both sides, Fixed Division were extended；Fixed Division c71 is connected for fixing with bent axle c4, keep out arm c72 for salient point c83 against；After being arranged by which, convenient installation and production, structure is the most reasonable.
A kind of wheel described in the present embodiment, keeps out arm c72 and is equipped with a groove, also includes a stator c73, stator c73 affixed with bent axle c4 and is arranged in groove.Being fabricated to this structure, first can be welded on bent axle c4 by stator c73, then be inserted directly into groove, just complete the setting of horizontal block c7, which is rational in infrastructure, convenient installs, and beneficially large-scale production, is beneficial to promote yields.
A kind of wheel described in the present embodiment, described in keep out the free end of arm c72 be wedge shape, described clutch chamber c82 is also wedge shape.Keeping out of wedge shape contacts the most smooth, that raising child rides experience sense with expanding the when that arm c72 free end can making to keep out arm c72 rotation between block c8.Clutch chamber c82 is that the wedge cavities with the wedge-like engagement keeping out arm c72 is so that when expanding block c8 and shrinking, clutch chamber c82 can effectively step down for keeping out arm c72 so that expands block c8 shrinkable more thorough.
A kind of wheel described in the present embodiment, described pit c61, convex stupefied c81 are multiple；Multiple convex stupefied c81 worked in coordination and pit c61 so that when expanding block c8 drive peripheral c6 rotation, frictional force is bigger, prevent skidding.
A kind of wheel described in the present embodiment, the other end of each expansion block c8 is equipped with snap fit c84, and two snap fit c84 are linked together by Flexible Connector.This structure can effectively prevent Flexible Connector from departing from expansion block c8, prevents clutch to lose efficacy.
A kind of wheel described in the present embodiment, Flexible Connector is an extension spring.Extension spring low cost, simple in construction, effective.Wheel rim c1 surface is provided with tire c2, strengthen wheel by property and comfortableness.
The above is only a preferred embodiment of the present utility model, therefore all equivalence changes done according to structure, feature and the principle described in this utility model patent claim or modification, it is included in the protection domain of this utility model patent application.
