Technical field

Field of mechanical technique is the utility model is related to, espespecially provides a kind of car wheel structure of child's bicycle.

Background technology

The child's bicycle of prior art, on the one hand as entertainment for children toy, on the other hand provide work of riding instead of walk for children Tool.Traditional bicycle comprises at least vehicle frame, handlebar and front and rear wheel, and vehicle frame is made up of forward and backward fork, wherein：Front and rear wheel passes through Axletree is separately mounted on forward and backward fork.However, single for the bicycle for meeting children's safety, wheel, car shaft design are not only It is durable, and will safely, it is attractive in appearance, and be easy to remove and repair.In the prior art, the rigid structure of cycle wheel is essentially car Formed between circle and axletree by the pull-up that interlocks of some steel wires.When vehicle wheel rotation, steel wire easily stirs clothing, finger, while steel Silk is easily also easily disconnected de- and stabs, pricks bad relative people and thing, has both been unfavorable for safety, also unsightly, this is one；Second, Bearing portion among wheel uses ball bearing and is combined into body by tightening device substantially, and professional is needed after damage Maintenance；Third, complexity is made, and automated production operation can not be realized.

The content of the invention

In order to solve the above technical problems, main purpose of the present utility model is the provision of a kind of wheel of child's bicycle Structure.

To reach above-mentioned purpose, the technical scheme of the utility model application is：A kind of car wheel structure of child's bicycle, bag Wheel and its trim of wheel both sides installation are included, wherein wheel includes wheel hub and surrounds the tire of wheel hub, and wheel hub includes foreign steamer Circle and inner rim, are connected between outer rim and inner rim by some supporting parts, wherein：Each supporting part has positioning respectively Portion, and be located in the form of surrounding inner rim between inner rim and outer rim, overlapped so that the center of circle of inside and outside wheel rim is in；Dress Decorative cover has decorative pattern, and is concentric circles relative to inside and outside wheel rim including centre bore and positioning hole, centre bore；Positioning hole is relative Set in the location of location division, trim is buckled in wheel hub both sides, and runs through positioning hole and location division by screw, is made with this Trim is firm integral with wheel hub.

It is preferred in the present embodiment：Inner rim includes inner ring, and inner ring has axle formed with wheel shaft in conjunction, wheel shaft Bearing bore.

It is preferred in the present embodiment：Inner rim has periphery, and outer rim has inwall；Supporting part has both ends, wherein：One End connection periphery, other end connection inwall.

It is preferred in the present embodiment：It is fan-shaped laying in each supporting part, between adjacent supporting part.

It is preferred in the present embodiment：Location division is perforation or screw hole.

Compared with prior art, it has the advantages that the utility model：With maintenance safe and easy to use, system Into can automated job.

Brief description of the drawings

Fig. 1 is the assembly structure diagram of the utility model embodiment.

Fig. 2 is Fig. 1 decomposing schematic representation.

Fig. 3 is the structural representation of wheel in Fig. 2.

Fig. 4 is the structural representation of trim in Fig. 2.

Embodiment

Although the utility model can easily show as various forms of embodiments, it is shown in the drawings and at this What be will be explained in specification is only some of specific embodiments, while is understandable that this specification is construed as The utility model principle it is exemplary illustrated, and be not intended to by the utility model be restricted to it is illustrated herein as.

Thus, a feature pointed in this specification is by illustrating one embodiment of the present utility model wherein One feature, rather than imply that each embodiment of the present utility model must have illustrated feature.Further it is to be noted that It is that present specification describes many features.Although some features can be combined to show possible system design, These features can also be used for other combinations that explanation is not known.Thus, unless otherwise indicated, illustrated combination is not intended to Limitation.

In the embodiment shown in the figures, the instruction (such as upper, lower, left, right, front and rear) in direction is explaining this practicality The structure of new various assemblies and motion are not absolute but relative.When these components are in position shown in the drawings When, these explanations are suitable.If the explanation of the position of these components changes, the instruction in these directions is also corresponding Ground changes.

Below in conjunction with the accompanying drawing of this specification, further elaboration is given to preferred embodiment of the present utility model.

Refer to Fig. 1 and combine and refer to Fig. 2, Fig. 1 is the assembly structure diagram of the utility model embodiment, and Fig. 2 is Fig. 1 Decomposing schematic representation.Figure includes the trim 20 of the both sides installation of wheel 10 and its wheel 10.

Please continue to refer to Fig. 1, Fig. 2 and combine refering to Fig. 3 and Fig. 4, Fig. 3 be wheel 10 structural representation, wheel in figure 10 include wheel hub 11 and surround the tire 12 of wheel hub 11, because the combining form of tire 12 and wheel hub 11 is prior art, herein It is not described in detail.In the present embodiment, wheel hub 11 includes outer rim 111 and inner rim 112, outer rim 111 and inner rim 112 Between be connected by some supporting parts (not marking), wherein：Each supporting part is located at inner rim in the form of surrounding inner rim 112 Between 112 and outer rim 111 (such as：The periphery of supporting part one end connection inner rim 112, other end connection outer rim 111 inwall), and It is fan-shaped equidistant laying between each supporting part, it (is same both i.e. to be allowed to outer rim 111 to overlap with the center of circle formation of inner rim 112 The heart is justified).In the present embodiment, supporting part (not marking) is provided with location division 113, and location division 113 is tied relative to (such as trim 20) Structure is closed as perforation or screw hole；Fig. 4 is the structural representation of trim 20, and trim 20 is presented with aesthetic feeling decorative pattern in figure, and Including centre bore 21 and positioning hole 22, wherein：Centre bore 21 is concentric circles relative to inner rim 112, and positioning hole 22 is relative to wearing The correspondence position of hole or screw hole is set.In the present embodiment, trim 20 is two panels, is buckled in the both sides of wheel hub 11 respectively, then lead to Cross screw to fix, because the structure that screw is fixed belongs to conventional techniques, no longer elaborate herein.In the present embodiment In, for inner rim 112 formed with the wheel shaft 13 being combined into one with its inner ring, wheel shaft 13 substitutes traditional ball bearing, and has Directly hold the axle hole (not marking) of bicycle middle shaft loading (not shown), with the combination of this structure, be both beneficial to operation is made, Convenient use is repaired.
