The utility model has the characteristics of long service life, receive that gravity is big, the noise is little, simple to operate, the wheel rolls in a flexible way and non -deformable etc.
Description
Technical field
This utility model relates to a kind of hollow wheel, particularly relates to a kind of novel case and bag hollow wheel.
Background technology
Existing hollow wheel on market, is all bearing when rolling and ball rolls, therefore with bearing simultaneously
Structure deformation face be easy to abrasion, occur that the gap, Structure deformation face of bearing and bearing can be increasing,
Thus produce the situation that noise even occurs that wheel comes off；And the cavity of this hollow wheel is all design
Circular, owing to stress surface is few, therefore little by gravity, wheel deformation easily occurs when case and bag drop, breaks
Situation about splitting, leverages the service life of wheel.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of novel case and bag hollow wheel, and it has makes
By life-span length, the feature such as big by gravity, noise is little, easy for installation, wheel rolls flexibly and is unlikely to deform.
This utility model solves above-mentioned technical problem by following technical proposals: a kind of novel case and bag
Hollow wheel, it is characterised in that it includes hub, rivet, support, wheel, wheel is installed by rivet
On support, support has the square hollow chamber radially offered, and both sides, square hollow intracavity side are respectively provided with
There is support draw-in groove；Wheel includes wheel body and bearing, and in support square hollow chamber, outward flange is respectively provided with
There is locating slot, bearing inner ring wall is respectively arranged with the location that coincide relative with cavity outward flange on support
Tooth, is respectively arranged with the ball grooves being equal to mutually on bearing outer ledge, and ball is embedded in ball grooves,
Wheel body medial wall is provided with ball orbit.
Preferably, described ball orbit is concave structure.
Preferably, it is provided with fixing lid outside described wheel, inside fixing lid, is provided with lumen square boss,
The both sides of square boss are respectively arranged with a fixing buckle.
Positive progressive effect of the present utility model is: for like product on market, this practicality is new
Type has length in service life, big by gravity, noise is little, easy for installation, wheel rolls flexibly and the most variable
The advantages such as shape.
Accompanying drawing explanation
Fig. 1 is the structural representation after a kind of novel case and bag hollow wheel of this utility model assembles.
Fig. 2 is the structural representation before a kind of novel case and bag hollow wheel of this utility model assembles.
Detailed description of the invention
Provide this utility model preferred embodiment below in conjunction with the accompanying drawings, to describe skill of the present utility model in detail
Art scheme.
As depicted in figs. 1 and 2, a kind of novel case and bag hollow wheel of this utility model includes hub 1, rivet
2, support 3, wheel 4, wheel 4 is arranged on support 3 by rivet 2, and support has radially to be offered
Square hollow chamber, both sides, square hollow intracavity side are respectively arranged with support draw-in groove 6；Wheel includes wheel
Body 11 and bearing 7, in support square hollow chamber, outward flange is respectively arranged with locating slot 5, bearing inner ring
It is respectively arranged with the positioning tooth 9 that coincide relative with cavity outward flange on support on wall, passes through bearing inner ring
Positioning tooth on wall inserts on support in the outer peripheral locating slot of cavity, wheel is rack-mount,
Being respectively arranged with the ball grooves 8 being equal to mutually on bearing outer ledge, ball 10 is embedded in ball grooves,
Wheel body is provided with ball orbit 12 on medial wall, ball appear part with on wheel body medial wall
Ball orbit contacts, and ball orbit is concave structure, ball can be allowed to roll more smooth and easy, also play ball
Position-limiting action；It is provided with fixing lid 13 outside wheel, is provided with lumen square boss inside fixing lid, side
The both sides of shape boss are respectively arranged with on a fixing buckle 14, the size of square boss and rack body
Square hollow chamber matches, be positioned at the fixing buckle of square boss both sides square with on rack body respectively in
Support draw-in groove in cavity matches, and connects and fixes wheel.Owing to using square hollow chamber and square convex
Platform designs so that being increased by gravity face of hollow wheel, thus solves case and bag and go out when dropping or being the heaviest
The situation that existing wheel deforms, ruptures；Simultaneously because wheel only has ball in motion when rolling, and axle
Hold motionless, thus greatly reduce Structure deformation face, effectively solve bearing and produce with Structure deformation face
Abrasion and the big problem in the gap that occurs so that wheel life-span length, noise are little.
Only need during installation first ball to be installed in the ball grooves on bearing, then bearing by bearing inner ring wall
On fixing tooth insert be positioned in the locating slot on the outward flange of support square hollow chamber, wheel body installation
On bearing, more fixing one end covering square boss is inserted in the square hollow chamber on support, profit
In the support draw-in groove being connected on support in square cavity with the fixing buckle of square boss both sides, with this
Fix wheel.
Particular embodiments described above, to of the present utility model solving the technical problem that, technical scheme and
Beneficial effect is further described, and be it should be understood that and the foregoing is only this utility model
Specific embodiment, be not limited to this utility model, all in spirit of the present utility model with former
Within then, any modification, equivalent substitution and improvement etc. done, should be included in guarantor of the present utility model
Within the scope of protecting.
