Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a spoke nipple head. Background Art

[0002] The wheel rim maintains a solid and reliable circular state by using the left and right ends of the axle to extend between the rims, with multiple spokes being tensioned simultaneously, so that the rim can rotate and roll smoothly on the road. Therefore, the key to obtaining a solid and reliable wheel rim is whether the spokes can be evenly tightened.

[0003] The existing wheel rims are connected to the spokes and rims by spoke caps (or copper caps), and the spoke tension can be further adjusted. Fig.12 As shown, the existing spoke nipple 60 includes a shaft 61 for connecting the spokes and a radial stopper 62 radially protruding from the shaft 61, a washer 63 is sleeved on the shaft 61, the spoke nipple 60 is inserted through the radial through hole of the rim with the shaft 61, and the radial stopper 62 is blocked at one side of the rim. However, the inner diameter of the washer 63 is larger than the outer diameter of the shaft 61, so when installing the spokes, the washer 63 is easy to fall off from the shaft 61, causing great trouble in the installation operation.

[0059] The following is combined with Figure 1-11 The utility model is described in further detail.

[0060] Please refer to Figures 1 to 5 In the first embodiment, the spoke nipple head 1 comprises a shaft 10 for connecting the spokes 101 and a radial stop 20 radially protruding from the shaft 10, the shaft 10 comprises a large diameter portion 11 and a small diameter section 12, the small diameter section 12 is located between the large diameter portion 11 and the radial stop 20, the outer diameter of the large diameter portion 11 is larger than the outer diameter of the small diameter section 12 and smaller than the outer diameter of the radial stop 20, the shaft 10 of the spoke nipple head 1 is passed through the radial through hole 102 of the wheel rim 100 and the radial stop 20 is blocked at one side of the wheel rim 100. Therefore, a cushion (such as a washer) can be limited between the radial stop 20 and the large diameter portion 11 without being arbitrarily dislodged and falling off, which is convenient for installation.

[0061] The shaft 10 includes a first end 13 and a second end 14, at least one of which is a non-circular outer circumference (e.g., a quadrangular, hexagonal, or a shape that is convenient for matching with a disassembly tool), and the shaft 10 is provided with an inner screw hole 15 that is screwed with the spoke 101. Preferably, both the first end 13 and the second end 14 are non-circular outer circumferences, and the spoke nipple 1 and the spoke 101 can be locked, loosened, and the tension of the spoke can be adjusted separately or simultaneously on the inner and outer sides of the wheel rim 100. In this embodiment, the large diameter portion 11 is arranged around the outside of the shaft 10. In other possible embodiments, the large diameter portion 11 includes at least one convex point convexly arranged on the shaft 10, and the convex point can be a single convex point or a plurality of convex points arranged at intervals. The spoke nipple 1 includes a first gasket 30, the inner diameter of which is not greater than the radial dimension of the radial stop 20 and greater than the radial dimension of the small diameter section 12, and the first gasket 30 is located between the radial stop 20 and the large diameter portion 11. Among them, applying force to the first gasket 30 can force the inner hole of the first gasket 30 to pass through the large diameter portion 11. Since the inner diameter of the first gasket 30 is not larger than the radial dimension of the radial stop protrusion 20, the first gasket 30 can be effectively confined between the radial stop protrusion 20 and the large diameter portion 11.

[0062] like Figure 4 As shown, the radial stop 20 includes an annular abutment surface 21, which tapers toward the large diameter portion 11. When the spoke 101 is tensioned, the annular abutment surface 21 can automatically guide and balance the tension, and can prevent the spoke 101 from bending or deforming due to lateral force. The first gasket 30 includes two upper and lower parallel side surfaces 31, a circumferential inclined surface 32 connected to the outer ends of the two side surfaces 31, and a tapered hole 33 that passes through the two side surfaces 31 and tapers toward the large diameter portion 11, and the hole wall of the tapered hole 33 is opposite to the annular abutment surface 21. When the spoke 101 is tensioned, the hole wall of the tapered hole 33 can automatically guide and balance the tension relative to the annular abutment surface 21, and can prevent the spoke 101 from bending or deforming due to lateral force.

[0063] like Figures 6 to 9 As shown, in the second embodiment, the large diameter portion 11 includes at least one radial groove 111 (for example, two radial grooves 111 arranged opposite to each other in radial direction, or more radial grooves 111 are provided), the spoke cap head 1 includes a second gasket 40, and the inner circumference of the second gasket 40 is provided with at least one clamping protrusion 41 (for example, two radially oppositely arranged clamping protrusions 41 are provided, or more), and at least one clamping protrusion 41 of the second gasket 40 passes through at least one radial groove 111, so that the second gasket 40 is located between the radial stop protrusion 20 and the large diameter portion 11. The second gasket 40 can be effectively restricted between the radial stop protrusion 20 and the large diameter portion 11. The second gasket 40 can also be similar to the first gasket 30 in the first embodiment, and the inner circumference of the second gasket 40 can also include a tapered hole 42 (such as Fig. 7A and 7B ).

[0064] like Figure 10 to Figure 11 As shown, in the third embodiment, the large diameter portion 11 includes at least one first radial protruding tooth 112, the spoke cap head 1 includes a third gasket 50, and the inner circumferential surface of the third gasket 50 is provided with at least one second radial protruding tooth 51, and at least one of the at least one first radial protruding tooth 112 and the at least one second radial protruding tooth 51 is a circumferential spiral extension. In this embodiment, the at least one first radial protruding tooth 112 and the at least one second radial protruding tooth 51 are respectively screw teeth extending in the circumferential spiral. The inner diameter of the third gasket 50 is smaller than the radial dimension of the large diameter portion 11 located at the at least one first radial protruding tooth 112, and the third gasket 50 can be rotated and moved between the radial stop 20 and the large diameter portion 11, so the third gasket 50 can be effectively confined between the radial stop 20 and the large diameter portion 11.

[0065] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
