The specific embodiment

In the tandem wheel structure of the utility model embodiment, all about all around, top and bottom, top and bottom and level and vertical reference, only be used for conveniently being described, be not to be used to limit the utility model, its member neither be limited to any position or direction in space.In the diagram and specification in specified size, can in scope of the present utility model, change according to specific embodiment of the utility model and real needs.Be illustrated in figure 3 as tandem wheel wheel carrier structure of the present utility model, this wheel carrier structure end face can be used for optionally locking establishes a base 20 (referring to shown in Figure 1), and base 20 can be used for coating boots 30 in is set, for the user with foot wear be stated from boots 30 inside, wherein same as the prior art about the structure of base 20 and interior boots 30, repeat no more.

Fig. 3 to Fig. 5 is the preferred embodiment of tandem wheel wheel carrier structure of the present utility model, and this wheel carrier structure comprises that holder 50 and at least one are installed on the wheels 6 of holder 50 bottoms with the linear fashion sequence.Wherein holder 50 is the platysome that is used for fixing the base 20 of aforesaid interior boots 30, holder 50 is provided with at least one wedge seat 51 that the front and back linear fashion is arranged that is, on holder 50, be provided with two wedge seats 51 in the present embodiment, lay respectively at the front-end and back-end of holder 50, wedge seat 51 bottom surface leading edges protrude out downwards be provided be used to guide smoothness that wheels 6 rotate dial briquetting 52, wheels 6 lock on the wedge seat 51 by wheel seat axle 53 and locking part 54 pivots, but the axis of the wedge seat 51 of wheels 6 relative fixed seats 50 freely rotates, and holder 50 rear ends are provided with a downward brake component that is used to brake 15.

As Fig. 4 and shown in Figure 6, wheels 6 comprise wheel seat 60 and roller 70, the upper and lower bearing 61 that is respectively equipped with in the axle center of wheel seat 60, and wheel seat 60 is hubbed on the wheel seat axle 53 of wedge seat 51 by two bearings 61 up and down.The angle theta that has an acute angle between the axis L2 of wheel seat 60 and the vertical axis L1 of wedge seat 51, wheel seat 60 end faces are formed with and are used for dialling the ccontaining annular groove 62 that briquetting 52 slides relatively, a side setting relative with dialling briquetting 52 in this ccontaining annular groove 62 has stop block 63, dials briquetting 52 and stop block 63 ccontaining annular groove 62 is separated into two semicircular accommodation spaces.Holding shape at two semicircles of ccontaining annular groove 62 puts and is respectively equipped with first return unit 64 and second return unit 65 in the space, and first return unit 64 and second return unit 65 can produce a bounce after being subjected to dial briquetting 52 slip extruding, make wheel seat 60 after being subjected to torsion deflection, can after torsion disappears, set back by relative fixed seat 50; Wheel seat 60 extends back and is provided with two relative and off-centre off-axis and stretches sheet 68, and aforementioned roller 70 is located at the free end that off-centre is stretched sheet 68 by wheel shaft 75 horizontal pivots.Because wheels 6 tiltedly are pivoted and place on the holder 50, and roller 70 departs from the design of the axis of wheels 6 backward, makes when rolling before the roller 70 and produces an oblique component forward, to promote the forward drive power of tandem wheel.Thereby group constitutes one is easy to conversion direct of travel and the good tandem wheel wheel carrier structure of forward drive performance.

As Fig. 3 and shown in Figure 5, when the user at the operation tandem wheel when advancing, because roller 7 departs from the axis setting of wheels 6, and wheels 6 are hubbed on the holder 50 by wedge seat 51, make the axis L2 and the vertical axis L1 of wheels 6 have the angle theta of an acute angle, thereby roller 70 is departed from backward, when roller 70 rolls forward, can produce an oblique component forward, and then can improve the forward drive power of tandem wheel, save operator's muscle power.

Because wheels 6 are hubbed on the wedge seat 51, make wheels 6 can drive roller 70 relative fixed seats 50 and freely rotate, when the user changed center of gravity, wheels 6 can drive roller 70 and relatively rotate, thereby effectively changed the motion direct of travel of tandem wheel.After wheel seat 60 had been subjected to torsion deflection, first return unit 64 and second return unit 65 were subjected to dial briquetting 52 slip extruding and produce bounce, and under the effect in bounce after torsion disappears, wheels 6 relative fixed seats 50 can homing.

The tandem wheel wheel carrier of the utility model embodiment needn't change direct of travel in the side pressure mode as the tandem wheel of prior art when changing direction, therefore the technical need of integrated operation is comparatively simple, can not only increase the convenience of changing direction in the motion process, and can allow the user do the action of more complexity, thereby effectively promote the interest of tandem wheel operation.Because wheels 6 can produce driving force forward, but and wheels 6 more relative fixed seat 50 freely rotate, therefore its action is more quick, simple, its radius of turn that changes direction is less simultaneously, even at climb and fall, the space is less or uneven environment, also can realize the purpose quickening and turn to easily, thereby can promote the security of operation.

The above is the specific embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection domain of the present utility model.
