Rubbish container with wheel

The rubbish container that the present invention relates to be made of plastics, its shape approximation is in upright bucket, and this rubbish container has lid and two wheels of a pivot joint, and these two wheels are connected on the footstalk with axially aligning mutually, and are installed in the recess of rubbish container bottom.

Among the Already in various embodiment of such rubbish container.Most of wheel wherein all is mounted on the continuous metal shaft, attempting to cancel recently, the trial of the metal shaft of costliness gets more and more, when rubbish container recycled in the future, metal shaft had just been brought problem, because it is made by another material.Thereby, resemble utility model G9307297, a solution has just been proposed, wherein, have wheel, tire at least and fastener that wheel is fixed on the axle is made of plastics.Continuous metal shaft has been cancelled fully, and footstalk directly is moulded on the rubbish container, so that wheel is mounted thereto, still, described footstalk is easier to fracture.Other solution of the prior art has all proposed the footstalk of belt wheel, but need be by the add ons of making than expensive material, and these additional elements are installed in also needs the operation of adding on the rubbish container.

Therefore, basic mission of the present invention provides a kind of later-model rubbish container, and the manufacturing of its wheel and assembly part and assembling are all very easy, and additional part also seldom.

In this later-model rubbish container, this task is achieved in that installation sleeve is set in recess exactly, and this installation sleeve links into an integrated entity by several ribs and rubbish container, and the footstalk and the installation sleeve of wheel have constituted blocking device, and footstalk can axially be located.

Thereby, only needing the footstalk that wheel is installed is pushed in the installation sleeve, these two parts will automatically lock together.In addition, do not need the installation procedure of other wheel.

In order to form this blocking device, the free end of footstalk preferably is provided with several grooves, as four grooves, these grooves all with parallel axes, and along circumferentially distributing, thereby, formed elastomeric colulus in the end of footstalk.These elastomeric colulus have the hook of the harpoon shape of directed outside, and this hook can be engaged on to locking the end of two installation sleeves from the oblique extension in the end of footstalk.In order to adapt to the hook of harpoon shape, installation sleeve can be provided with circumferential inward flange at a suitable end.

Footstalk is preferably hollow, and columnar in other words conj.or perhaps, its internal diameter dwindles along a conical surface near hook.At the front end of footstalk, have outward extending circumferential flange by several sections die casting all-in-one-piece steady arms at a end, and have the coronal that is similar to flange at an other end towards footstalk.Steady arm can be pushed in the hole of footstalk end by damaging described several sections bars.At the end position of steady arm, the conical surface of the in-to-in respective end of flange and footstalk cooperatively interacts.In case steady arm is pushed into place, colulus just contracts in no longer, and the hook of colulus end just can be not again be separated with the end of footstalk.

Between the inboard of the outside of footstalk and installation sleeve, can be provided with by having the transition lining that suitable sliding capability, anti abrasive material are made, this transition lining especially can be suitable rigid plastic, even can be metallic material.At rubbish container is under the situation about being made by polyethylene, for instance, after having experienced so-called self-hardening, can make this transition lining with polyethylene.

Installation sleeve is to be linked into an integrated entity by the bottom of osed top rib structure and rubbish container not, and this installation sleeve is connected in the above-mentioned recess, and this recess may also be referred to as roller box.

Rubbish container of the present invention especially can all be made of plastics, and especially, by a kind of and be with a kind of plastics, makes as polyethylene.Comprise wheel, this rubbish container has only several parts, and these parts are also uncomplicated comparatively speaking, also is easy to link together.

An embodiment of wheel of the present invention is described below in conjunction with Fig. 1.This wheel comprises wheel rim 10 and footstalk 12 on the whole.Wheel rim 10 comprises flange way 14, cylinder hub 16 and annular disk 18, and annular disk 18 is connecting flange way 14 and cylinder hub 16 on the middle face of wheel.The right side of cylinder hub by one slightly the shaft shoulder 20 of undergauge link to each other with the uniform columnar footstalk 12 of internal diameter.The shaft shoulder 20 is strengthened by rib 22, and rib 22 along the circumferential direction distributes.

From the right side of Fig. 1 as can be seen, the external side end of footstalk 12 has position 24, and the vertical section at this position 24 is different with the vertical section of the uniform columnar footstalk 12 of internal diameter.At 26 places, position at the beginning that constitutes position 24, the diameter at this position 24 begins to strengthen slightly.26 ends to footstalk from the position are four

sub-positions

28,30,32 and 34 successively, the shape difference at these four sub-positions, and diameter is also different.The inside and outside both sides at the first sub-position 28 all are the faces of cylinder, and the inside and outside both sides at the second sub-position 30 are all tapered towards the line of centers 36 of footstalk.The inside and outside both sides at next sub-position 32 all are again the faces of cylinder, and still, its internal diameter is less than the internal diameter of footstalk 12.Last sub-position 34 is the outward flange shape, and from the end of footstalk, it is shaped as barb-shaped.

Furtherly, whole position 24 is divided into four parts by four grooves 38, is divided into four

colulus

40 and 42 in other words conj.or perhaps, and

colulus

40 and 42 is along circumferentially distributing, and four grooves 38 all are parallel to the axle center, and are provided with in the square crossing mode.If adopt suitable plastics, colulus 40 just can contract in spring with 42.

At the front end of footstalk 12, promptly the right-hand member of Fig. 1 shows a steady arm, and this steady arm is by code 44 expressions, and steady arm 44 is connected on the footstalk by gross weight (not illustrating).In this way, wheel, footstalk and steady arm 44 can injection moulding be one.Hereinafter also will be in conjunction with the accompanying drawings 6 shape and the functions that steady arm is described in further detail.

Fig. 2 shows the tire of wheel rim shown in Figure 1 10, and this tire is made by tartan, can directly injection moulding on wheel rim.Hereinafter also to be described in more details tire.

The present installation sleeve of 3 to 5 explanation footstalks 12 in conjunction with the accompanying drawings, and this installation sleeve is arranged on the mode of the bottom of rubbish container.In Fig. 3 to 5, the rubbish container shown in the part is by code 46 expressions.Two adjacent corners in the bottom of rubbish container are provided with recess 48, and this recess may also be referred to as roller box.In recess 48, two installation sleeves 50 are connected the outside that strengthening rib 54,56,58,60 and 62 (seeing Fig. 3 and 5) is connected rubbish container with 52 (seeing Fig. 3,5 and 6) by several.Each rib extends to different directions from the side face of installation sleeve, and therefore, wheel can bear the application force from different directions.Rib 54 and 58, and extends along the whole width of rubbish container along vertically extending in the both sides of installation sleeve, thereby two installation sleeves are also interconnected, and has further produced booster action.Other rib all is provided with and has a certain degree, and the same wide with the length of the relative qualification of installation sleeve.

Below in conjunction with accompanying drawing 6 relation between installation sleeve and the footstalk 12 is described in further detail.

Fig. 6 shows the wheel and the footstalk 12 of belt wheel edge 10, and this has mentioned in Fig. 1.The tire of being made by neoprene 64 as shown in Figure 2 is arranged on the wheel rim 10.

At the medial extremity of installation sleeve 50, promptly an end of the installation sleeve that does not illustrate in Fig. 6 towards another one is provided with peripheral inward flange 66, and this inward flange 66 is inboard tapered to installation sleeve.The shape of the vertical section of inward flange 66 is accurately corresponding at the sub-position 30 of the external side end of the footstalk described in Fig. 1 12 and 32 profile.Therefore, when footstalk 12 when the left side of Fig. 6 is inserted in the installation sleeve 50, the sub-position 34 of the hook-type of the end of footstalk 12 will be resisted against on the conical surface of inward flange 66.This can make in the

position

40 and 42 of hook-type at position 24 and contract, and reaches position shown in Figure 6 until

position

40 and 42, at this moment, the hook at the sub-position 34 in the outside by inward flange 66 lockings be engaged on the end face of installation sleeve 50.Under this position, do not need to take any other measure, footstalk 12 just is locked in the installation sleeve 50.

The steady arm of simply having mentioned in Fig. 1 44 is used for further making footstalk 12 location.This steady arm only is connected on the footstalk 12 by gross weight (not illustrating).On the outer peripheral face of the end of the most contiguous footstalk 12, steady arm is provided with circumferential flange 68, and the both sides of this flange all are the conical surfaces, and in the so-called outer end of an other side, this steady arm has coronal 70, and this coronal 70 stretches out as the flange.

If steady arm 44 is pushed in the footstalk, so,

position

40 and 42 is just at first against the flange 68 of the band conical surface of steady arm 44, reaches the position by the sub-position of code 30 expressions of footstalk 12 until this flange 68, and this sub-position 30 has the conical surface as circular cone along the direction of steady arm.Flange 68 is engaged on the conical surface at the back side at sub-position 30.Simultaneously, coronal 70 is resisted against on the end face of footstalk 12 from the outside.On this position, steady arm can not be pulled out, and more can not drop out.Contract in no longer in the

position

40 and 42 of footstalk, therefore, wheel and footstalk just are permanently secured in the installation sleeve.

Fig. 6 also shows thin transition lining 72, and this transition lining 72 is between the outside of the inboard of installation sleeve 50 and footstalk 12, and the scope of its extension has surpassed the length of the cylinder hub 16 from installation sleeve to wheel.The material of making this transition lining 72 is bigger than the material hardness of the other parts of making rubbish container, thereby, can play a part to strengthen and reinforce to footstalk 12, simultaneously, this transition lining 72 also has good sliding capability, and this is for the plastics of the adjacency of footstalk and/or installation sleeve.Also can adopt proper metal, can also adopt the plastics harder, have the plastics of big self-hardening modulus as employing than the plastics of making rubbish container.

It can also be seen that from Fig. 6 the transition lining is such location in the axial direction, fixing by a flange (not illustrating) of cylinder hub 16 on the one hand exactly, in addition on the one hand, fix by the shaft shoulder at 26 places, position outside the footstalk.
