Description
[technical field]
The utility model relates to case and bag, particularly relates to higher case and bag of a kind of stability and universal wheel component thereof.
[background technology]
The installed surface of traditional case and bag is provided with universal wheel component.When these case and bag were static, this universal wheel component was used to support these case and bag; When these case and bag moved, this universal wheel component played the effect that these case and bag are supported in rolling simultaneously.
See also Fig. 1, a kind of universal wheel component 220 of case and bag, it comprises connecting portion 2232 and wheel support 222.The axis of connecting portion 2232 overlaps with the rotating shaft of wheel support 222.Therefore, when these case and bag were equipped with a plurality of universal wheel component 220 and come these case and bag of together support, the area that the touchdown point of all universal wheel component 220 surrounds was less than the area of installed surface.
But, when the object of adorning in this casing is overweight, because this casing has only universal wheel component 220 to support, if the therefore support force deficiency that produced of universal wheel component 220 at this moment, then these case and bag universal wheel component 220 of crushing easily.Too high when excessive when these case and bag, because the center of gravity of these case and bag is too high, therefore, if the stability that this moment, universal wheel component 220 was produced is not enough, then these case and bag are dropped to laterally inclined easily.
[utility model content]
Based on this, be necessary the case and bag that provide a kind of stability higher.
A kind of case and bag comprise casing and universal wheel component.This universal wheel component is located at the installed surface of this casing.This universal wheel component comprises wheel, wheel support, wheel seat, bearing and rotating shaft.One end and this wheel of this wheel support are rotatably connected.This wheel seat comprises fixed part and connecting portion.This fixed part is fixed on this installed surface.This connecting portion extends from a side of this fixed part.The free end of this connecting portion is rotationally connected with the end of this wheel support away from this wheel, and the axis of this connecting portion extends with respect to the axes of rotation skew of this wheel support and to the middle part away from this installed surface.This bearing is located between this wheel support and this wheel seat.This rotating shaft wears this wheel support, this bearing and this wheel seat, so that this wheel seat is rotatable with respect to this wheel support.
In traditional universal wheel component, the axis of this connecting portion overlaps with the rotating shaft of this wheel support.Therefore, when these case and bag were equipped with a plurality of these universal wheel component and come these case and bag of together support, the scope that touchdown point surrounded of all these universal wheel component generally equaled the scope of this installed surface.If this moment, object that these case and bag adorns was overweight or these case and bag are too high, owing to the scope that touchdown point surrounded of all these universal wheel component is big inadequately, these case and bag collapse easily or inclination is from the side dropped.And the axis of above-mentioned connecting portion extends with respect to the axes of rotation skew of this wheel support and to the middle part away from this installed surface; So this universal wheel component can be outstanding to the outside of this casing; When causing this universal wheel component to land; Compared to traditional design, the scope that touchdown point surrounded of all these universal wheel component is relatively large.Therefore, the stability of these case and bag is stronger.
