Abstract
The utility model discloses a front axle drum of a portable bike. The front axle drum of the portable bike comprises an axle drum body, lateral caps, and attaching-stopping screws, wherein the axle drum body is sleeved on middle tubes, and bearings are installed in the positions, close to two ends of the axle drum body, between axle drum body and the middle tubes. According to the front axle drum of the portable bike, the bearings are used for replacing steel balls, the frictional force of the axle drum in the process of rotation is largely reduced, and the portability of the whole bike is largely improved in the riding process. In addition, the bearings are standard, so that the axle drum is easier to assemble.
Description
Technical field:
The utility model relates to the bicycle spare parts and accessories technical field, especially relates to a kind of bicycle hub structure.
Background technology:
The problems such as there is complex structure in flower-drum before the existing bicycle, parts are many, volume is large, portability is not good have very large impact for the performance of bicycle, are necessary to be improved.
The utility model content:
The purpose of this utility model is to provide the weak point that exists for prior art and flower-drum before a kind of hand-held design bicycle is provided, and it has characteristics simple in structure, that volume is little, portability is good.
For achieving the above object, flower-drum includes flower-drum body, side cover, ends attached screw before the hand-held design bicycle of the present utility model, and the flower-drum body is sleeved on the middle pipe, and the position near flower-drum body two ends between described flower-drum body and the described middle pipe is equipped with bearing.
Preferred as technique scheme is equipped with O type ring in the described side cover.
Preferred as technique scheme, the outside of described side cover has embossing.
The beneficial effects of the utility model are: it replaces steel ball with bearing, greatly reduce the friction force of flower-drum in rotation process, therefore, can greatly improve in the process of moving the portability of bicycle integral body, in addition, because bearing is a gauge member, make flower-drum when assembling, also be more prone to simple.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
Therefore the following stated only for embodying the preferred embodiment of the utility model principle, does not limit protection domain of the present utility model.
As shown in Figure 1: flower-drum includes flower-drum body 1, side cover 2, ends attached screw 3 before the hand-held design bicycle of the present utility model, flower-drum body 1 is sleeved on the middle pipe 4, near flower-drum body 1 end positions bearing 5 is installed between flower-drum body 1 and the described middle pipe 4, O type ring 21 is installed in the side cover 2, and the outside of side cover 2 has embossing 6.After the utility model was installed on the bicycle, the bicycle wheel body drove flower-drum body 1 by blade and rotates when rotating, and flower-drum body 1 moves in a circle around middle pipe 4 by bearing 5.
