Description
Technical field
The utility model relates to hairbrush fields, and in particular to a kind of coaxial hairbrush roller bearing of high-precision.
Background technique
In the prior art, usually there is inside and outside roller bearing low precision in hairbrush.Especially through use after a period of time,
Will appear inside and outside roller bearing it is asynchronous, it is eccentric, shake the case where, it is inconvenient for use so as to cause hairbrush, brush it is uneven, effect is poor.
Summary of the invention
The purpose of the utility model is to provide a kind of coaxial hairbrush roller bearings with high accuracy.
In order to achieve the above objectives, the technical solution adopted in the utility model is: a kind of coaxial hairbrush roller bearing of high-precision, including
Outer roller bearing, the interior roller bearing being arranged concentrically, the outer roller bearing are set in outside the interior roller bearing, and the outer roller bearing outer surface is provided with brush
Batt, is provided with multiple groups tension spring between the interior roller bearing and the outer roller bearing, described tension spring one end is fixed at the interior rolling
Axis outer wall, the other end are fixed on the outer roller bearing inner wall by inserted block；It is provided between the interior roller bearing and the outer roller bearing more
Group support rod, described support rod one end is fixed at the interior roller bearing outer wall.
Preferred technical solution, the inserted block are dove-tail form, are provided with and the inserted block shape on the outer roller bearing inner wall
The dovetail groove matched.
Preferred technical solution, tension spring described in one group is along the interior roller bearing central axis setting and is arranged in a straight line.
Preferred technical solution, support rod described in one group is along the interior roller bearing central axis setting and is arranged in a straight line.
Preferred technical solution, the support rod are vertically set on the outer wall of the interior roller bearing.
Preferred technical solution, the support boom end are spherical surface.
Preferred technical solution, the tension spring are provided with 3 groups.
Preferred technical solution, tension spring described in multiple groups are uniformly distributed around the interior roller bearing.
Preferred technical solution, tension spring described in one group include at least 3 tension springs.
The outer diameter ratio of preferred technical solution, the outer roller bearing and the interior roller bearing is 2: 1.
Since above-mentioned technical proposal is used, the utility model has the advantage that compared with prior art
1, the utility model is provided with multiple groups tension spring and multiple groups support rod, and tension spring can make to reduce shake between inside and outside roller bearing, and
Support rod is able to ascend the same axial ratio of inside and outside roller bearing, so that hairbrush roller bearing has high-precision coaxial rate, so that hairbrush uses effect
Fruit is good.
Detailed description of the invention
Fig. 1 is the utility model main view；
Fig. 2 is the utility model tension spring, support rod cross-sectional view.
Wherein: 1, layers of brush bristles；2, outer roller bearing；3, interior roller bearing；4, inserted block；5, tension spring；6, support rod.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments:
Embodiment one:
As shown in Figs. 1-2, the coaxial hairbrush roller bearing of a kind of high-precision, including outer roller bearing, the interior roller bearing being arranged concentrically, outer roller bearing
It is set in outside interior roller bearing, outer roller bearing outer surface is provided with layers of brush bristles, and three groups of tension springs, tension spring are provided between interior roller bearing and outer roller bearing
One end is fixedly installed in interior roller bearing outer wall, and the other end is fixed on outer roller bearing inner wall by inserted block；It is set between interior roller bearing and outer roller bearing
Three groups of support rods are equipped with, support rod one end is fixedly installed in interior roller bearing outer wall.
Inserted block is dove-tail form, is provided with the dovetail groove matched with inserted block shape on outer roller bearing inner wall.
One group of tension spring is arranged and is arranged in a straight line along interior roller bearing central axis.
One group of support rod is arranged and is arranged in a straight line along interior roller bearing central axis.
Support rod is vertically arranged on the outer wall of interior roller bearing.
Support boom end is spherical surface.
In the present embodiment:
Three groups of tension springs are uniformly arranged, and the angle between two adjacent groups tension spring is 120 °.Three groups of support rods are uniformly arranged, and adjacent two
Angle between group support rod is 120 °.Support rod and tension spring interval are arranged.When in use, tension spring can disperse inside and outside average come from
The power of roller bearing, so that hairbrush roller bearing monolithic stability, does not shake.And support rod can be resisted from the biggish power of outer roller bearing, be guaranteed
Outer roller bearing relative to interior roller bearing without departing from.Therefore, tension spring and support rod are used in combination that can to reach inside and outside roller bearing higher same
Axial ratio, so that hairbrush be made to obtain preferable using effect.
