Specific implementation mode
The possible embodiment of the present invention is only illustrated with embodiment below, is not so to limit the model of the invention to be protected
Farmland is stated in advance.
It please refers to Fig.1 to 4, shows that the preferred embodiment of the present invention, bicycle bottom bracket bowl group 1 of the invention include extremely
A few tube body 10 and an at least bearing 20.
For wearing group in a Five-way tube 2, each tube body 10 is equipped with the perforation 11 and one that one axially penetrates through and supplies an at least tube body 10
The axial breeze way 12 being set in Five-way tube 2, breeze way 12 are equipped with an at least support construction 121 and an at least recess portion 122；At least
One bearing 20 is set to perforation 11, in it is radially least partially overlapped with an at least support construction 121 and with an at least recess portion 122 to
Small part is overlapped；Wherein, when the breeze way 12 of an at least tube body 10 is set in Five-way tube 2, an at least support construction 121 is radial
Support for Five-way tube 2 and at least a recess portion 122 and 2 spaced radial of a Five-way tube at least cushion space.With this, the structure of breeze way 12
Intensity is strong and effectively buffers active force (such as oppressive force and twisting resistance) of the Five-way tube 2 to each bearing 20, therefore each tube body 10
And each bearing 20 is unlikely to deform, has longer service life, processing cost relatively low.In addition, each bearing 20 can be anchored on each pipe
Body 10 is with smooth transmission.
In this present embodiment, at least the quantity of a tube body 10 is two, and at least the quantity of a bearing 20 is two, two bearings
20 are respectively arranged in the breeze way 12 of two tube bodies 10.Wherein, tube body 10 can be but not be limited to the materials such as plastic cement or metal.
Each tube body 10 defines an axis L, from radial, 121 out of plumb axis L of an at least support construction；At least one support
Structure 121 can be obliquely installed, the L that parallels to the axis setting or above-mentioned arbitrary combination；In this present embodiment, an at least support construction
121 is are arranged in parallel with axis L, to resist the active force of Five-way tube 2 with preferable structure.
An at least support construction 121 and at least a recess portion 122 is located on breeze way 12；Preferably, an at least support construction
121 and at least one recess portion 122 shift to install, connect with Five-way tube 2 and respectively active force with firm.In this present embodiment, at least
One support construction 121 is plural number, and an at least recess portion 122 is plural number, and plural support construction 121 and plural recess portion 122 can be single
Or multiple rows of matrix arrangement, annular arrangement, radiation arrangement etc.；Each support construction 121 can be round, polygonal body, square body, item
The arbitrary combination of line body or above-mentioned geometrical body, each support construction 121 is the longitudinal bodies of elastically deformable in this present embodiment；
