Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.
As shown in Figure 1 and Figure 2, a kind of bowl group structure of the present embodiment, at least include rotating shaft 10, trip bolt 12 and expansion assembly.Its shaft 10 is as it is shown on figure 3, one end of this rotating shaft 10 is provided with end cap 11, and one end of this end cap 11 is provided with scalene cone 14.Being provided with screwed hole away from one end of end cap 11 in rotating shaft 10, this screwed hole is for spinning with trip bolt 12.
The expansion assembly of the present embodiment includes the annular knurl post 30 and the chamfering pad 50 that are mutually matched.As shown in Figure 4, wherein annular knurl post 30 is circulus, and the wall of this annular knurl post 30 offers axially extended fluting 33, and the effect of this fluting 33 is in that, thus it is possible to vary the radial dimension size of annular knurl post.Annular knurl post 30 two ends of the present embodiment are provided with inner conical surface 34, and surface is provided with the embossing 31 for increasing frictional force, and as preferably, this embossing 31 is Argyle, are provided with cannelure 32 in the middle of embossing, and in installation process, this cannelure 32 plays the role of positioning.
As it is shown in figure 5, one end of the chamfering pad 50 of the present embodiment is provided with the male cone (strobilus masculinus) 51 matched with above-mentioned inner conical surface 34.Under installment state, male cone (strobilus masculinus) 51 is bonded to each other with inner conical surface 34.As increased the interaction force between chamfering pad 50 and annular knurl post 30, then the fluting 33 of annular knurl post 30 becomes big, makes the radial dimension of annular knurl post 30 become big.
The bowl group structure of the present embodiment also includes the bearing 70 and the bearing mounting base 20 that are sheathed in rotating shaft 10, and the outer ring of its middle (center) bearing 70 is connected with bearing mounting base 20 interference.It should be noted that be provided with gap between the bearing inner race of the present embodiment and rotating shaft 10, and it is connected by bearing regulation of mental activities ring 60 is fixing between bearing 70 with rotating shaft 10.As shown in Figure 6, the bearing regulation of mental activities ring 60 of the present embodiment includes annular body 61, and one end of this annular body 61 is provided with the extension ring body 63 axially extended, and the wall thickness of this extension ring body 63 is less than the gap between rotating shaft 10 and bearing inner race.
Additionally, be provided with inclined-plane inside the inner ring of bearing 70, and it is provided with intermediate incline 62 between annular body 61 and extension ring body 63, the slopes which match inside this intermediate incline 62 and bearing inner race.With extending, the outer wall of ring body 63 is additionally provided with the groove 64 axially extended in above-mentioned annular body 61.Under installment state, extend in the ring body 63 gap between rotating shaft 10 and bearing inner race, the inclined-plane laminating inside intermediate incline 62 and bearing inner race.As increased the interaction force between bearing regulation of mental activities ring 60 and bearing 70, under the interaction of intermediate incline 62 and bearing inner race medial slope, groove 64 diminishes, and the radial dimension of bearing regulation of mental activities ring diminishes, thus holding rotating shaft tightly, simultaneously work as location regulation of mental activities and the effect being fixedly clamped.
Further, it is angular contact ball bearing that the bearing 70 in the present embodiment is preferably, and certainly, this is a kind of optimal way simply, and is not the sole limitation to the present embodiment.
Fig. 7 show a kind of bicycle partial schematic diagram using above-mentioned bowl group structure.In this embodiment, bicycle includes stem 80, vehicle frame 90 and bowl group structure.Wherein stem 80 is provided with two standpipe fixtures 81 being parallel to each other, and this standpipe fixture 81 is provided with symmetrical counterbore, and this counterbore includes macropore 82 and aperture 83, and wherein macropore 82 is used for holding end cap 11 and trip bolt 20；Aperture 83 is used for holding annular knurl post 30.Vehicle frame 90 is provided with the mounting groove 91 for installing bearing mounting base 20 and holds the through hole that rotating shaft is passed through.
In end cap 11 side, being provided with elastic washer 40 between end cap 11 and annular knurl post 30, this packing ring is preferably nylon washer.The scalene cone 14 of end cap 11 is fitted with the inner conical surface 34 of annular knurl post 30, and the inner conical surface of this annular knurl post other side is then fitted with chamfering pad 50.What be close to chamfering pad is then bearing regulation of mental activities ring 60, and this bearing regulation of mental activities ring 60 then interacts with bearing 70, and bearing 70 is installed in bearing mounting base 20, and bearing mounting base is installed in the mounting groove 91 of vehicle frame 90.
In trip bolt 20 side, being provided with elastic washer 40 between trip bolt 20 and annular knurl post 30, this packing ring is preferably nylon washer.The both sides of this annular knurl post 30 are equipped with a chamfering pad 50, and two chamfering pads 50 symmetrically, and interact with annular knurl post 30.What be close to the chamfering pad away from trip bolt side is then bearing regulation of mental activities ring 60, and this bearing regulation of mental activities ring 60 then interacts with bearing 70, and bearing 70 is installed in bearing mounting base 20, and bearing mounting base is installed in the mounting groove 91 of vehicle frame 90.
In said structure, by rotational lock screw, make each parts being set in rotating shaft extrude to centre, and then make the inner conical surface of chamfering pad male cone (strobilus masculinus) and annular knurl post interact, make annular knurl post expanded radially so that the outer wall of annular knurl post in the counterbore of standpipe fixture between hold tightly；Meanwhile, the inclined-plane inside the intermediate incline of bearing regulation of mental activities ring and bearing inner race interacts so that bearing regulation of mental activities ring shrinks and holds rotating shaft tightly.This bowl group architecture is simple, takes up room less, and meets structural rigidity demand, has better complied with the light-weighted development trend of bicycle.
In a word; the foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model, all any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included within protection domain of the present utility model.
