Description

Luggage wheel

Technical field

The utility model relates to the case and bag that bottoms such as a kind of luggage wheel that is used for, especially draw-bar box have wheel.

Background technology

Wheel structure in the case and bag of Xiao Shouing generally as shown in Figure 1 in the market, the rotating shaft mounting groove of wheel arrangement comprises the bearing installation groove at two ends in its structure, connect by the rotating shaft jack between the two bearings mounting groove, and an axostylus axostyle and two bearings are disposed in rotating shaft, two bearings was in the bearing installation groove when rotating shaft was fit in the rotating shaft mounting groove, and axostylus axostyle passes the rotating shaft jack.The rotating shaft of the luggage wheel of this structure, especially bearing are exposed outside, so long-term use makes moist easily and get rusty, and perhaps collided with and damage, so service life is shorter, and the effect of wheel turns is also relatively poor.Two bearings of another one wheel arrangement have increased material and cost of installation, increase assembly difficulty, and therefore manufacturing and material cost are higher.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of simple in structure, easily manufactured and luggage wheel that can effectively bearing be isolated from the outside.

For this reason, the luggage wheel that the utility model provides, comprise wheel body and rotating shaft, rotating shaft comprises axostylus axostyle and bearing, the wheel body center offers the rotating shaft resettlement groove with the rotating shaft coupling, one side of rotating shaft resettlement groove has dividing plate, has first axis hole that passes for rotating shaft on the dividing plate, the external opening of the opposite side of rotating shaft resettlement groove, opening part disposes side cover plate, have second axis hole on the side cover plate, rotating shaft is inserted in the rotating shaft resettlement groove, and wherein the axostylus axostyle of a side passes axis hole, one end of bearing is adjacent to dividing plate, the axostylus axostyle of rotating shaft opposite side passes second axis hole, and side cover plate seals the resettlement groove opening part and is adjacent to the other end of bearing, and side cover plate and bearing are provided with fastening mechanism.

Because in the rotating shaft setting and rotating shaft resettlement groove of the luggage wheel that the utility model provides, rotating shaft is by dividing plate and side cover plate sealing, the bearing portions of its shaft is isolated from the outside, therefore can prevent effectively that bearing and rainwater etc. from contacting, prevent that it from being corroded or the damage of being collided with, and the independent rotating shaft resettlement groove of this set, and an independent rotating shaft can be inserted and adopt side cover plate osed top structure very simple in the groove, and be convenient to make, can effectively reduce material cost and manufacturing cost.

The specific embodiment

As Fig. 2, shown in Figure 3, the luggage wheel that the utility model provides comprises wheel body 1 and rotating shaft 2, rotating shaft 2 comprises axostylus axostyle 3 and is fixed on the bearing 4 of axostylus axostyle 3 centres, wheel body 1 center offers the rotating shaft resettlement groove 5 with rotating shaft 2 couplings, one side of rotating shaft resettlement groove 5 has dividing plate 6, have first axis hole 7 that passes for rotating shaft 2 on the dividing plate 6, the external opening of the opposite side of rotating shaft resettlement groove 5, opening part disposes side cover plate 8, have second axis hole 9 on the side cover plate 8, rotating shaft 2 is inserted in the rotating shaft resettlement groove 5, wherein the axostylus axostyle 3 of a side passes axis hole 7, and an end of bearing 4 is adjacent to dividing plate 6, and the axostylus axostyle 3 of rotating shaft 2 opposite sides passes second axis hole 9, side cover plate 8 seals resettlement groove 5 opening parts and is adjacent to the other end of bearing 4, and side cover plate 8 is provided with fastening mechanism with bearing 4.

As Fig. 2, Fig. 3, Fig. 4, shown in Figure 6, rotating shaft resettlement groove 5 external opening parts have step surface 6 in the annular on the basis of the foregoing description, side cover plate 8 be arranged in the annular in the step surface 6 and, the outer wall of side cover plate 8 is concordant with wheel body 1 sidewall, this structure makes side cover plate 8 difficult drop-offs, and makes wheel more attractive in appearance.

As Fig. 4, Fig. 5, shown in Figure 7, on the basis of the foregoing description, fastening mechanism comprises the slot 10 that offers on step surface 6 inwalls 12 in the annular, have inserted block 11 on the sidewall of side cover plate 8 with slot 10 couplings, inwall 12 close-fittings of step surface 6 in the sidewall of side cover plate 8 and the annular, inserted block 11 inserted in the slots 10 when side cover plate 8 was arranged in the interior step surface 6 of annular, and inserted block 11 and slot 10 close-fittings, this buckled up structure is very simple, and is convenient to the operation of fastening and dismounting (only need prize with rod member during dismounting and get final product).Slot 10 can be made the narrow structure in position wide by the position of sidewall, in the outer part in the present embodiment, and this structure can effectively be pinned inserted block 11, and it can not deviate from from sidepiece easily.
