Description
Technical field
It the utility model is related to the attachment structure of a kind of rim spoke hole and spoke cap.
Background technology
The species of rim has a lot, such as plastics rim, carbon fiber rim, metal rim.Some rim is direct
It is made of one with spoke, is connected by spoke and rotating shaft, the most use of this structure is on plastics rim.Have in addition
When in use, it is necessary to can be connected additionally by spoke with rotating shaft, this kind of rim then needs pre- a part of rim
The mounting hole of installation spoke is stayed, majority is related to carbon fiber rim and metal rim.
Need the rim of reserved spoke mounting hole, the periphery of spoke mounting hole is its more fragile position, and spoke
The peripheral position of mounting hole needs to bear the huge stress of spoke cap, and in actual use, rim is often just from spoke mounting hole
Periphery it is cracking, crackle spreads to other positions from the periphery of spoke mounting hole again.Therefore, existing this kind of rim is present
The defects of spoke mounting hole periphery is easily cracking, service life is shorter.
Utility model content
The utility model provides the attachment structure of a kind of rim spoke hole and spoke cap, which overcomes background technology and is deposited
Deficiency.Technical scheme is used by the utility model solves its technical problem：
A kind of rim spoke hole and the attachment structure of spoke cap, rim include be arranged symmetrically dual side-edge, respectively symmetrically connect
Be connected on two brakes on dual side-edge outer end edges edge while, the interior base that is connected between the edge of dual side-edge the inner, be connected to two brakes while
Between outer bottom edge, the outer bottom edge and two brake skirts into installation tire tire groove, interior base, outer bottom edge and the dual side-edge enclose
Into cavity, the interior base is provided with spoke hole, and the interior base is located at the center of the inner surface of the cavity inside to should spoke
Hole is provided with hemispherical groove, and the hemispherical groove is connected with the spoke hole, and spoke cap passes through the spoke hole, the spoke cap it is outer
Cokled surface forms spherical or hemispherical protuberance, and the protuberance is rotatably arranged among the hemispherical groove.
Among one preferred embodiment：The spoke hole deviates the center on the interior base, and the axis of the spoke hole is passed through
The centre of sphere of the hemispherical groove.
Among one preferred embodiment：The wall thickness on the interior base is more than the wall thickness of the side.
Among one preferred embodiment：The diameter of the hemispherical groove is 6-8mm.
Among one preferred embodiment：The inner surface on the interior base is a plane.
Among one preferred embodiment：The outer surface on the interior base is arcwall face and rounding off connection dual side-edge.
Compared with background technology, it has the following advantages that the technical program：
The inner surface on the interior base is molded the hemispherical groove, and the outer surface of the spoke cap heaves to form protuberance, should be partly
Ball recess can carry the protuberance, increase the lifting surface area of spoke cap and rim, so as to improve the carrying on spoke hole periphery
Ability, effectively prevent that spoke hole peripheral position is cracking, improve the service life of rim.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 depicts the schematic diagram of the attachment structure of rim spoke hole and spoke cap.
Fig. 2 depicts longitudinal schematic cross-sectional view of rim spoke hole shown in Fig. 1 and the attachment structure of spoke cap.
Fig. 3 depicts rim spoke hole shown in Fig. 1 and the horizontal schematic cross-sectional view of the attachment structure of spoke cap (omits spoke
Cap).
Embodiment
Fig. 1 to Fig. 3, rim spoke hole and spoke cap attachment structure are refer to, rim 10 includes two sides being arranged symmetrically
While 11,12 when being respectively symmetrically connected to two brake on dual side-edge outer end edges edge, the interior bottom that is connected between the edge of dual side-edge the inner
While 13, when being connected to two brakes between outer bottom edge 14.The outer bottom edge 14 and two brake side 12 surrounds the tire groove of installation tire
15.Interior base 13, outer bottom edge 14 and the dual side-edge 11 surround cavity 16.The interior base 13 is provided with spoke hole 132, the spoke hole
132 are used to install spoke 20.The interior base 13 be located at the center of the inner surface inside the cavity 16 to should spoke hole set
There is hemispherical groove 134, the hemispherical groove 134 is connected with the spoke hole 132.During installation, spoke cap 30 passes through the spoke
The glomerate protuberance 32 of shape is heaved in hole 132, the outer surface of the spoke cap 30, and the protuberance 32 is rotatably arranged in the hemisphere
Among connected in star 134, one end of the spoke 20 is strained and fixed by the spoke cap 30.
It is to be appreciated that as long as the protuberance 32 has a lower arcuate surface to match with the hemispherical groove 134, the protrusion
The can of portion 32 is easy to rotate in the hemispherical groove 134, therefore, the protuberance 32 can also be it is hemispherical, either
The hemispherical structure of other approximations.
The spoke hole 132 deviates the center on the interior base 13, and the axis of the spoke hole 132 is recessed by the hemispherical
The centre of sphere of groove 134.The diameter of the hemispherical groove 134 is 6-8mm.
The wall thickness on the interior base 13 is more than the wall thickness of the side 11.The inner surface on the interior base 13 is a plane.The interior bottom
The outer surface on side 13 is arcwall face and rounding off connection dual side-edge 11.
It is described above, only the utility model preferred embodiment, therefore the utility model implementation can not be limited according to this
Scope, i.e., the equivalent changes and modifications made according to the utility model patent scope and description, it is new all should still to belong to this practicality
In the range of type covers.
