Description
Technical field
The utility model belongs to luggage technical field, is related to a kind of roller for luggage.
Background technique
The mobile luggage for being equipped with universal wheel of the prior art, universal wheel is fixed on cabinet, when universal disc sharpener
After damage, to not replaced with the universal wheel after the replacement abrasion of new universal wheel, because the universal wheel being fixed on cabinet is
It does not tear open not get off.
Existing Chinese patent literature discloses a kind of dismountable universal wheel for case【Authorization Notice No. CN202335491U】,
Including wheel carrier, bracket cover, rotating mechanism and mechanism for assembling-disassembling, mechanism for assembling-disassembling includes card larynx axis, dismounts switch, card lozenge and spring,
Rotating mechanism includes iron plate on iron plate, ball and ball under bracket, ball, and card larynx and location hole are provided on card larynx axis, is propped up
Iron plate under frame, ball, ball, iron plate, bracket cover and wheel carrier are sequentially assembled together with card larynx axis from bottom to top on ball, idler wheel
Mechanism and bracket are assembled together, and the card larynx being arranged on card lozenge and card larynx axis is matched in engaging or discrete state, in wheel carrier
On be provided with switch mouth and spring groove, switch convex block and spring convex block are provided on card lozenge, positioned at tearing open for the switch mouth
Dress switch and switch convex block are assembled together, and spring one end and the spring convex block positioned at the spring groove are assembled together,
The other end contradicts wheel carrier inner wall.It is equipped with card larynx axis between above-mentioned bracket cover and bracket, passes through positioning between card larynx axis and card larynx axis
Pin is fixed, and although which is able to achieve the fixation of card larynx axis and bracket cover, but need the equal aperture on card larynx axis and bracket cover
It is passed through for positioning pin, so that the processing of bracket cover and card larynx axis is more complicated, cost is higher, while needing card larynx during installation first
Hole alignment on axis and bracket cover, then positioning pin is worn into entrance, so that installation is more complicated.
Summary of the invention
The purpose of this utility model is the presence of the above problem in view of the prior art, proposes a kind of roller for luggage, this reality
It is so that wheel seat and bracket cover structure are simpler and installation is more convenient with the technical issues of novel solution.
The purpose of this utility model can be realized by the following technical scheme：
A kind of roller for luggage, including fixing seat, wheel seat and the wheel being rotatably connected on wheel seat, the wheel seat and fixing seat
Between by shaft connect, the upper end of the wheel seat is rotatably connected to bracket cover, through-hole, institute is offered in the middle part of the bracket cover
Shaft is stated across through-hole, which is characterized in that the bracket cover is adopted made of plastic, offers on the hole wall of the through-hole symmetrical
Notch is located on the hole wall of the through-hole between two notches and opens up there are two groove, in the middle part of the bottom surface of two grooves
There are two the limiting sections of protrusion for tool, form card slot between two limiting sections, side and groove of the limiting section towards card slot
Plane perpendicular, the shaft pass through one section of through-hole it is upper there is symmetrically arranged strip, the strip can pass through notch, described turn
The lower end of axis has a limit flange, the limit flange energy and wheel seat against, the limit flange and wheel seat against when described in
The lower end of strip can be caught in card slot.
Minimum spacing between limit flange and strip is less than upper side and limit that bracket cover is installed in place rear limiting section
Minimum spacing between flange, the structure guarantee not falling out after strip is caught in card slot；Had using bracket cover made of plastics
Certain elasticity, during installation passes through shaft from the bottom of wheel seat, and the limit flange and wheel seat of shaft are against then by bracket cover set
In shaft, strip initially passes through notch, when bracket cover in place after rotating bracket lid, at this time the lower end of strip can be transferred to groove and with
Limiting section support is leaned on, and since bracket cover has elasticity, continuing to rotate bracket cover can make the downward deformation in limiting section position make strip
Lower end cross limiting section and be caught in card slot；Fixation and the fixation of bracket cover and shaft are realized by above structure, together
When since without being fixed by positioning pin, so that roller for luggage structure is simpler, installation is more convenient, saved and be produced into
This.
In above-mentioned roller for luggage, the bottom surface of the groove all has guiding surface one close to one section of notch, described
Guiding surface one is sloped downwardly to notch one.Limit flange and wheel seat against when shaft strip pass through through-hole, block at this time
The lower end of item is still located in notch and is located at the top of one downside of guiding surface, at this time rotating bracket lid, the lower end meeting of strip
It slides and is resisted against on the bottom surface of groove along guiding surface one, above structure can make strip, and more easily rotation is caught in card slot
It is interior.
In above-mentioned roller for luggage, the limiting section has guiding surface two close to one end of notch, and the guiding is oblique
The lower section in face two connects with the bottom surface of groove.Bracket cover, strip are continued to rotate when the lower end of strip is against on the bottom surface of groove
Lower end can be slid on the upper side of limiting section along guiding surface two, the lower end of final strip is detached from limiting section and is simultaneously embedded in card
Slot, above structure can make strip, and more easily rotation is caught in card slot.
In above-mentioned roller for luggage, the bottom surface of the bracket cover has thickening part in a ring close to through hole, described
The outside that the bottom surface of bracket cover is located at thickening part has grid-shaped reinforcing rib.Thickening part can increase bracket cover and be located at through hole
Intensity, when strip is stuck in card slot, bracket cover, which is located at through hole, can bear the pressure of strip；Reinforcing rib energy lifting bracket lid
The intensity at other positions and it is able to achieve lightweight.
In above-mentioned roller for luggage, thrust bearing is equipped between the bracket cover and wheel seat.It is realized by thrust bearing
Relative rotation between bracket cover and wheel seat.
Compared with prior art, this roller for luggage has fixation and the fixation of bracket cover and shaft, simultaneously because nothing
It need to be fixed by positioning pin, so that roller for luggage structure is simpler, installation is more convenient, has saved the excellent of production cost
Point.
