Further, described stress bearing is rolling bearing.
Further, be axially arranged with open column in described mounting groove, the adjustable column form fit on the core cavity of institute's post open column and knob support rotates to drive described adjustable column.
Further, described adjustable column is water chestnut post.
Further, described adjustable column is cylinder, and described adjustable column circumferential outer edge is provided with stress plane.
Further, the outer ring outside surface transition of described mounting groove and stress bearing or interference fit are installed.
Further, described knob body has decoration protective surface away from one end outer rim cover of knob support.
Further, described knob body is cylindrical structure, the axial adduction of outer rim that described knob body coordinates with decoration protective surface, to make the non-outer rim coordinated with decoration protective surface of the outer rim of decoration protective surface and knob body concordant.
Further, described decoration protective surface has scale groove.
Further, described decoration protective surface is provided with decorative pattern.
The utility model is coordinated with the fricton-tight of friction flange of knob support by pressure bearing inside surface, knob body is combined closely with knob support, not easily rocks, be out of shape, and extends the serviceable life of knob.
Additional aspect of the present utility model and advantage will part provide in the following description, and part will become obvious from the following description, or be recognized by practice of the present utility model.
Accompanying drawing explanation
Fig. 1 is assembly sectional view of the present utility model.
Fig. 2 is installation sectional view of the present utility model.
In figure: 1, knob body; 11, mounting groove; 12, open column; 121, core cavity; 13, decoration protective surface; 2, stress bearing; 21, outer ring; 22, inner ring; 3, knob support; 31, friction flange; 32, adjustable column.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, and to make those skilled in the art better can understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
As depicted in figs. 1 and 2, a kind of adjusting knob structure of the utility model, comprise knob body 1, knob body has hollowed out mounting groove 11, stress bearing 2 is installed in mounting groove 11, knob body 1 cooperation is installed on knob support 3, and knob support 3 is extended with friction flange 31 to knob body 1 direction, fricton-tight friction flange 31 outside surface being matched with knob support of inner ring 22 inside surface of stress bearing 2.Stress bearing 2 is preferably rolling bearing.More preferably, outer ring 21 outside surface transition or the interference fit of mounting groove 11 and stress bearing 2 are installed, and it should be pointed out that clearance fit can also realize order of the present utility model ground, but transition and interference fit make the utility model combine more closely, and effect is optimum.
Be axially arranged with open column 12 in mounting groove of the present utility model, the core cavity 121 of institute's post open column 12 rotates to drive adjustable column with adjustable column 32 form fit on knob support 3.In a kind of embodiment, adjustable column 32 be water chestnut post, and by coordinating of water chestnut post and adjustable column inner chamber, user is by the rotation drive adjustable column rotation of knob body., in another embodiment, adjustable column 32 is cylinder, and now, the circumferential outer edge of adjustable column is provided with stress plane, otherwise adjustable column can be caused to slide in open column 12 cavity of knob and do not have the effect coordinating and rotate.
As preferably embodiment, decoration protective surface 13 can be had in knob body 1 away from one end outer rim cover of knob support 3.More preferably; when knob body 1 is cylindrical structure; the axial adduction of outer rim that knob body coordinates with decoration protective surface; to make the non-outer rim coordinated with decoration protective surface of the outer rim of decoration protective surface 13 and knob body concordant; seem elegant in appearance to make knob; based on the function of knob, can scale groove be had or be provided with decorative pattern in decoration protective surface.
When the utility model uses, by coordinating of the open column of adjustable column and knob body, drive adjustable column to rotate, realize with regulating order.Meanwhile, due to coordinating of bearing and knob support, knob body can not be produced and rock and be out of shape, extend the serviceable life of knob.
