Description

Luggage wheel

Technical field

The present invention relates to a kind ofly for luggage wheel, especially the bottom such as draw-bar box is with the case and bag of wheel.

Background technology

Wheel structure in the case and bag of selling in the market generally as shown in Figure 1, the rotating shaft mounting groove of wheel arrangement comprises the bearing mounting 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 mounting 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, and therefore long-term use is made moist easily and got 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 matters to be solved by this invention provides a kind of simple in structure, easily manufactured and luggage wheel that can effectively bearing be isolated from the outside.

For this reason, luggage wheel provided by the invention, 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 is with dividing plate, with the first axis hole that passes for rotating shaft, the opposite side of rotating shaft resettlement groove is to outward opening on the dividing plate, and opening part disposes side cover plate, on the side cover plate with the second axis hole, rotating shaft is inserted in the rotating shaft resettlement groove, and wherein the axostylus axostyle of a side passes axis hole, and an end of bearing is adjacent to dividing plate, side cover plate seals the resettlement groove opening part and is adjacent to the other end of bearing, is provided with fastening mechanism on the step surface in side cover plate and the annular.

Because in the rotating shaft setting and rotating shaft resettlement groove of luggage wheel provided by the invention, 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 the structure of side cover plate sealing very simple in the groove, and be convenient to make, can effectively reduce material cost and manufacturing cost.

The specific embodiment

Such as Fig. 2, shown in Figure 3, luggage wheel provided by the invention comprises wheel body 1 and rotating shaft 2, rotating shaft 2 comprises axostylus axostyle 3 and bearing 4, wheel body 1 center offers the rotating shaft resettlement groove 5 with rotating shaft 2 couplings, one side of rotating shaft resettlement groove 5 is with dividing plate 6, the first axis hole 7 that passes with confession rotating shaft 2 on the dividing plate 6, the opposite side of rotating shaft resettlement groove 5 is to outward opening, opening part disposes side cover plate 8, on the side cover plate 8 with the second axis hole 9, rotating shaft 2 is inserted in the rotating shaft resettlement groove 5, wherein the axostylus axostyle 3 of a side passes axis hole 7, one end of bearing 4 is adjacent to dividing plate 6, and side cover plate 8 seals resettlement groove 5 opening parts and is adjacent to the other end of bearing 4, is provided with fastening mechanism on the step surface in side cover plate 8 and the annular.

Such as Fig. 2, Fig. 3, Fig. 4, shown in Figure 6, rotating shaft resettlement groove 5 external opening parts are with step surface in the annular on the basis of above-described embodiment, side cover plate 8 be arranged in the annular in the step surface 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.

Such as Fig. 4, Fig. 5, shown in Figure 7, on the basis of above-described embodiment, fastening mechanism comprises the slot 10 that offers on the step surface inwall 12 in the annular, on the sidewall of side cover plate 8 with the inserted block 11 of slot 10 coupling, inwall 12 close-fittings of step surface 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 of annular, and inserted block 11 and slot 10 close-fittings, the structure of this fastening 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.
