Abstract

The utility model relates to an improved suitcase roller group which is characterized in that a fixing element comprises a body and a threaded rod, which is an integral forming. The body is made of elastic material. When the body is in the integral forming, the end head of a shaft rod is buried in the body. A rolling wheel is pivoted on the shaft rod, and the tail end of the shaft rod protrudes the outer side of the rolling wheel. A block stopping part is arranged at the head end of the shaft rod. The utility model is widely used for various suitcases with knock resistance.

Description

Improved suitcase roller group

The utility model relates to luggage case, refers to a kind of roller set of luggage case especially.

As shown in Figure 1: existing luggage case roller set 10, include a stator 11, but its mat screw 12 is fixed on the predetermined position of luggage case 13 lower ends, bolt 14 is arranged in these stator 11 lower ends and the along continuous straight runs suitable length that extends outwardly, elastic washer 15, first pad 16 are sheathed on the outboard end of bolt 14 successively with ring set 17, roller 18 is sheathed on ring set 17 outer rims, second pad 19 is set on bolt 14 outboard ends that protrude from roller 18, nut 20 is locked in bolt 14 ends, and wheel cap 21 is embedded at roller 18 outsides.This roller set 10 finds to have following shortcoming in the use: one, after roller 18 long-term the rotations, 20 on bolt 14 and nut take place loosening, come off to cause roller 18; Though 18 flexible packing rings 15 of two stators 11 and roller, when roller 18 was impacted, impact was mostly vertically from ground, so elastic washer 15 hits shock-proof effect to this no much helping.

The purpose of this utility model is to have above-mentioned shortcoming and provide a kind of structure through improved luggage case roller set at existing luggage case roller set, to improve shock-proof effect.

The purpose of this utility model is achieved in that structure is through improved luggage case roller set, comprise fixture, roller, it is characterized in that fixture includes body and screw rod, and it is one-body molded, body is made for omiting the tool elastomeric material, and axostylus axostyle is embedded in this body with its head end when this body by integral forming; Roller is hubbed on this axostylus axostyle, and the tail end of axostylus axostyle protrudes in its outside, and the stop section is fixedly arranged on the head end of axostylus axostyle.

Above-mentioned design makes this roller no matter be subjected to parallel or during perpendicular to the impact of the axis direction of this axostylus axostyle by this, but its impulsive force partly of the flexible bulk absorption of mat tool, thus reaching the effect of damping, the stop section then can prevent to deviate from when axostylus axostyle is stressed.

Below by drawings and Examples the utility model is described further again:

Fig. 1 is existing luggage case roller set organigram;

Fig. 2 is the utility model embodiment organigram;

Fig. 3 is the utility model embodiment decomposing schematic representation.

Among the figure: 10,30 rollers and; 11 stators; 12,43 screws; 13,32 luggage cases; 14 bolts; 15 elastic washers; 16 first pads; 17 ring sets; 18,36 rollers; 19 second pads; 20,58 nuts; 21,52 wheel caps; 34 fixtures; 40 bodies; 41 fixed parts; 42 perforation; 44 connecting portions; 45 axostylus axostyles; 46 screw threads; 47 flanges; 48 grooves; 49 stop sections; 50 axis holes; 51 hole clippings; 53 card articles; 54 grabs; 55 first packing rings; 56 axle sleeves; 57 second packing rings.

Fig. 1,2 is for axially to analyse and observe along roller set, as seen from the figure: wherein, said stop section in the axostylus axostyle head end be provided with prevent this axostylus axostyle when stressed by this groove of locating to deviate from.Wherein, said stop section is fixedly driving fit among being embedded in this groove in body head end of body when integrally formed.Wherein, said groove, its two neighbour forms has certain thickness flange.Wherein, said flange is the polygon cylinder coaxial with this axostylus axostyle.Wherein, this axostylus axostyle tail end is provided with screw thread, nut, and the roller outside is embedded with wheel cap, and the inboard of this wheel cap is corresponding to this nut outside, and takes turns to cover in this and be provided with card article, the grab that stretches into the roller hole clipping, and this wheel cap is fastened on the roller.

Be also shown in by figure, the fixed part of fixture is fan-shaped and is provided with three screws of three little perforation confessions thereon by the bottom of passing and be locked in this luggage case therebetween, and a junction is located at the axis part of this fan-shaped fixed part, and the suitable thickness of tool; One axostylus axostyle is that metal material is made, and its tail end is provided with screw thread, and head end then is equipped with the hexagonal cylindrical lip of two suitable distances of being separated by, and forms a groove therebetween.And this axostylus axostyle is embedded in this connecting portion with its head end when this this body by integral forming, and the material that forms this body can be embedded in this groove, and this axostylus axostyle can't be broken away from outside body.This roller has an axis hole, opening four hole clippings and a wheel cap outwardly, this wheel cap is slightly in the form of sheets and on one is distolateral, be provided with four card articles of the suitable length that extends outwardly, and respectively the end of this card article is respectively equipped with a grab, make this wheel cap can be by the cooperating of hole clipping and card article, to be fixed in this roller outside.During combination, prior to sheathed in regular turn from inside to outside one first packing ring of this axostylus axostyle and an axle sleeve, this axle sleeve is arranged in this roller axis hole, and the tail end of this axostylus axostyle partly slightly protrudes from this roller outside, be located on the tail end of this axostylus axostyle with one second gasket sleeve again, screw on nut again, just this wheel cap is fixed in outside this roller then.During use, the axostylus axostyle head end is embedded on the connecting portion of this body in one-body molded mode, therefore can't deviate from and this nut owing to there is this wheel cap to be limited to its outside with its inner side end, therefore also can't get loose by the tail end of this axostylus axostyle, make to reach firm setting that this roller is unlikely to come off by this.Because this body is the tool elasticity and the suitable length of respectively being separated by between the axle center of this screw and this connecting portion slightly, the suitable length and this axostylus axostyle extends outwardly, make this fixture form a L shaped cantilever by this, therefore, when no matter this roller is subjected to bump from horizontal or vertical direction, by this body can be slightly the elasticity of crooked and reinstatement, can reach shock-absorbing in order to absorb its partly impulse force.Owing to be embedded among its connecting portion when this axostylus axostyle and this this body by integral forming, and this connecting portion can be in to forming a stop section by axostylus axostyle head end end terminal, therefore, this axostylus axostyle is also unnecessary to be provided with two flanges, and it only is provided with one also still can bring into play its unlikely effect that comes off.
