Owing to taked technique scheme, made to the utlity model has the vibrations that reduce baggage container, the advantage of the comfort when the increase user tows luggage.

Description of drawings

Fig. 1 is the longitudinal sectional view of the utility model one preferred embodiment.

The specific embodiment

Lifting a preferred embodiment and conjunction with figs. below is elaborated to the utility model.

As shown in Figure 1, be a kind of baggage container castor 10 of the utility model one preferred embodiment, constituted by a pedestal 20, a spring washer 30, a hard washer 40, a ball dish 50, a wheel seat 60, a pivot pin 70 and a roller 80 with damping effect.

Pedestal 20 is provided with an axis hole 21 that vertically connects.In the present embodiment, pedestal 20 windings are in the casing bottom side of baggage container, and certainly, pedestal 20 also can become the casing of baggage container itself.

Spring washer 30, made by elastic material (for example PU or rubber), be provided with a mesopore 31; Spring washer 30 pastes and is against pedestal 20 bottom surfaces, and the mesopore 31 of spring washer is involutory with the axis hole 21 of pedestal 20.

Hard washer 40 is made with metallic material, is provided with a mesopore 41; Hard washer 40 pastes the bottom surface that is against spring washer 30, and the mesopore 41 of hard washer 40 is involutory with the mesopore 31 of spring washer 30.

Ball dish 50 has a disk body 51, and disk body 51 is provided with a circular mesopore 52 and some through holes 53 around mesopore 52; Ccontaining respectively one ball that can roll flexibly 54 in each through hole 53, and each ball 54 exposes disk body, and about in the of 51 two sides; Ball dish 50 is located at hard washer 40 bottom sides, and each ball 54 top side touches in hard washer 40 bottom surfaces, and the mesopore 52 of disk body is involutory with the mesopore 41 of hard washer 40.

Wheel seat 60 is formed by connecting by a circular base plate 61 and two otic placodes 62 (one of them only is shown among the figure) one, and two otic placodes 62 are down extended in parallel by relative both sides, basal disc 61 bottom surfaces; Basal disc 61 centers are provided with an axis hole 63 that vertically connects; Wheel seat 60 is located at ball dish 50 bottom sides, and wheel seat 60 end faces and ball 54 bottom sides touch, and the axis hole 63 of wheel seat 60 is involutory with the mesopore 52 of ball dish 50.
