Abstract
The utility model discloses a clutching front wheel of a child tricycle, which comprises a wheel body formed from a side cover of the front wheel, wherein a wheel axle extends from both sides of the side cover of the front wheel, both ends of the wheel axle are provided with pedals, and a clutching positioning mechanism is arranged between the wheel body and the wheel axle. The wheel body and the wheel axle can be connected or disconnected by the clutching positioning mechanism. Thus, when an adult pushes the child tricycle to run, the wheel axle can not rotate along with a wheel, and feet of a child can put on the pedal and do not rotate round the wheel. When a child pedals the tricycle by self, the child tricycle can be driven to move forwards or backwards. The utility model has simple structure and can adapt to the tricycle riding learning requirements of children at different growth stages.
Description
Technical field
The utility model relates to a kind of child's tricycle wheel, but is a kind of child's tricycle disengaging type front-wheel specifically.
Background technology
Existing child's tricycle front-wheel, its front-wheel and front wheel spindle generally are fixed together, and front-wheel rotates around its axis with front wheel spindle, when children are loaded on the pedal at front wheel spindle two ends with the both feet driving, front wheel spindle drives front-wheel and rotates, and realizes advancing or falling back of three-wheel vehicle.But the three-wheel vehicle of this drive form has a drawback, when children have tired out oneself not to pedal, or children also can be not to pedal, but when walking by adult's go-cart, because axletree rotates with wheel, pedal is fought back the foot that gets to children when rotating with front wheel spindle, even children's footwear can be got rid of, also can injure children's pin when serious.
The summary of the invention the technical problems to be solved in the utility model provides a kind of child's tricycle wheel body and the relatively turnable disengaging type front-wheel of axletree.
For solving the problems of the technologies described above, the utility model comprises the wheel body that is made of the front-wheel side cover, and axletree stretches out from the both sides of front-wheel side cover, and the both ends of axletree are equipped with pedal, and its constructional feature is that the disengaging type detent mechanism is installed between wheel body and axletree.
Described disengaging type detent mechanism comprises the disk that places in the wheel body, and the center and the axletree of disk are fixed together, and the circumferential distribution of disk has some grooves; The position that covers away from the wheel body line of centers in front wheel side is provided with counterbore, is provided with the inclined-plane boss of symmetry along the counterbore internal perisporium, has axis hole on the counterbore inwall, passes axis hole with the cooresponding locating dowel pin of groove and is connected with knob in placing counterbore.
Be set with pull back spring and packing ring on locating dowel pin, packing ring places counterbore inwall inboard.
After adopting said structure, because the disengaging type detent mechanism is installed between wheel body and axletree, can realize between wheel body and the axletree interlock and separate by this disengaging type detent mechanism, thereby when walking by adult's go-cart, axletree does not rotate with wheel, children's both feet can rest on the pedal and needn't be round wheel turns, as children oneself to pedal the time, can drive advancing or falling back of three-wheel vehicle.It is simple in structure, can adapt to the different phase study needs by bike that children are growing.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the A-A of Fig. 1 to decomposition;
Fig. 3 is the structural representation of another kind of locating dowel pin;
Fig. 4 is the front view of disk.
The specific embodiment
With reference to accompanying drawing, but this child's tricycle disengaging type front-wheel fastens the wheel body 1 that constitutes by the front-wheel side cover 3 of two symmetries, axletree 7 stretches out from the both sides of front-wheel side cover 3, axletree 7 both ends are equipped with pedal 6, and the wheel body 1 that axletree 7 is installed is installed on the fork blade 9 of child's tricycle by front-wheel attaching parts 8.In order to realize between wheel body 1 and the axletree 7 interlock and to separate, between wheel body 1 and axletree 7, the disengaging type detent mechanism is installed.Disengaging type detent mechanism concrete form is: in wheel body 1, be provided with disk 2, disk 2 be contained on the axletree 7 by its center borehole jack and with axletree 7 affixed (welding) together, the circumferential distribution of disk 2 has some grooves 12; Position away from the wheel body line of centers on front-wheel side cover 3 is provided with counterbore 13, be provided with the inclined-plane boss 15 of symmetry along counterbore 13 internal perisporiums, have axis hole 16 on counterbore 13 inwalls, pass axis hole 16 with groove 12 cooresponding locating dowel pins 4 and be connected with knob 10 in placing counterbore 13, on locating dowel pin 4, be set with pull back spring 5 and packing ring 17, packing ring 17 places counterbore 13 inwall inboards, guarantees that locating dowel pin 4 has enough screen resiliences.When inclined-plane boss 15 made knob 10 revolve lofty perch by the inclined-plane low spot, the locating dowel pin 4 that links together with knob 10 broke away from the groove 12 of disks 2 peripheries, realized rotating between wheel body and the axletree and separated; Otherwise when knob 10 revolved lofty perch by the inclined-plane low spot of inclined-plane boss 15, the locating dowel pin 4 that links together with knob 10 plugged together with the groove 12 of disk 2 peripheries, realizes rotating interlock between wheel body and the axletree.
Certainly, the disengaging type detent mechanism is not limited to said structure, be provided with pin-and-hole as outer end with locating dowel pin 4, draw ring 11 is installed in this pin-and-hole, replaces original knob 10 with draw ring 11, by outside pulling draw ring 11, locating dowel pin 4 and groove 12 are broken away from, and draw ring 11 rotated 90 degree, draw ring 11 places the high point of inclined-plane boss 15, realizes rotating between wheel body and the axletree and separates; Otherwise, make draw ring 11 leave the high point of inclined-plane boss 15, locating dowel pin 4 and groove 12 are plugged together, realize rotating interlock between wheel body and the axletree.Certainly, two inclined-plane boss 15 can be the vertical boss 14 along counterbore 13 internal perisporiums, and be distributed in some grooves 12 of disk 2 peripheries can be uniform along disk 2 periphery, with locating dowel pin 4 cooresponding circular holes.All these variations all should fall into protection domain of the present utility model.
