When people go on a business trip or travel, the luggage case is often selected to contain the clothes which are carried with the luggage case, the bottom of the luggage case is provided with the rollers, the luggage case can move in multiple directions only by operating the pull rod, and the luggage case is labor-saving and convenient. As shown in fig. 1, the utility model patent of patent No. 201020229187.x wheel components including holding in the palm 1, support 2, wheel 3, support 2 and hold in the palm and be connected through a vertical axis 5 between 1, vertical axis 5's upper portion with hold in the palm 1 fixed connection, vertical axis 5 lower part and the 6 rotatable couplings of axle mounting hole that support 2 upper portion was equipped with, upper portion is equipped with boss 11 in the vertical axis 5, boss 11 is arranged in between support 2 and the support 1, and lower part is equipped with annular notch 7 in the vertical axis 5, is equipped with pinhole 8 on the support 2, and pinhole 8 is corresponding with the annular notch 7 position of vertical axis 5, is equipped with a horizontal pin 9 in the pinhole 8, and some card of horizontal pin 9 is gone into and is cooperated with annular notch 7 in the annular notch 7.
Wherein, the one end that support 2 and boss 11 offset is the plane, after luggage is loaded onto to the suitcase, the weight of whole box can be pressed on wheel components, hold in the palm 1 and drive boss 11 and the inseparable laminating of support 2, because the one end that support 2 and boss 11 offset are the plane, lead to the two laminating too inseparable, wheel 3 can't turn to in a flexible way, often need people to mention the suitcase and put down the wheel again and just can resume normal turning, it is very inconvenient to people on the way like this, if pull the suitcase by force, lead to wheel wearing and tearing, life subtracts the weak point.
In addition, in order to fix the vertical shaft 5, the horizontal pin 9 needs to be installed, the upper part of the vertical shaft 5 needs to be fixed with the bracket 1, two processes are needed, the production cost is increased, the assembly of workers is inconvenient, and the production efficiency is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that to the not enough of above-mentioned prior art, provide a novel wheel components, solved the suitcase and loaded the phenomenon that the universal wheel roll has the jamming after article, reduction in production cost, simple to operate.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a novel roller assembly, includes gyro wheel, pivot, axle sleeve, box connecting seat, the gyro wheel passes through pivot and bushing, the axle sleeve passes through connecting shaft, its characterized in that with the box connecting seat: the shaft sleeve comprises a first connecting portion connected with the rotating shaft and a second connecting portion connected with the box body connecting seat, a convex ring is arranged on the connecting end face of the second connecting portion, and the convex ring is higher than the connecting end face.
The utility model has the characteristics as above: set up the bulge loop on the axle sleeve connection terminal surface, the bulge loop is higher than the horizontal plane of connecting the terminal surface, replaces to connect the terminal surface and offsets with the box connecting seat, after the suitcase installs article in, under the action of gravity, the box connecting seat presses the bulge loop on the axle sleeve connection terminal surface, and the cambered surface is personally submitted in the contact of bulge loop, and the contact surface between the box connecting seat is less, can not appear leading to the gyro wheel jamming because of the unable rotation of axle sleeve, has improved roller components's flexibility ratio and practicality.
The utility model discloses further setting is: the connecting end face is provided with a first boss, and the convex ring is arranged on the first boss.
The utility model has the characteristics as above: first boss slightly is less than the area of connecting the terminal surface, the bulge loop sets up on first boss, do not directly set up on connecting the terminal surface, the setting of first boss has further prevented the direct contact of the terminal surface of being connected of box connecting seat and axle sleeve, the flexibility ratio that has strengthened the axle sleeve prevents the jamming, and in the mounting hole on the box connecting seat can be packed into just to first boss, can reciprocate along the connecting axle in the certain extent after the axle sleeve is installed, first boss has the guide effect, increase roller components's stability.
The utility model discloses further setting is: the connecting shaft is arranged in the box body connecting seat, and the lower end of the connecting shaft is fixedly connected with the shaft sleeve.
The utility model has the characteristics as above: the upper end of the connecting shaft is fixedly connected with the box body connecting seat, the lower end of the connecting shaft is fixedly connected with the shaft sleeve, the fixed connection modes are riveting, workers only need to rivet twice to fixedly connect the shaft sleeve with the box body connecting seat, the assembly steps are simplified, and the production efficiency is improved; the connecting shaft extends out of the lower end opening of the mounting through hole, so that the mounting through hole of the shaft sleeve can wrap the whole connecting shaft, the connecting shaft is effectively protected, and the connecting shaft is prevented from being bent or broken due to uneven stress in the using process.
The utility model discloses further setting is: the upper end of the connecting shaft is sleeved with a gasket, and the gasket is arranged between the convex ring and the box body connecting seat.
The utility model has the characteristics as above: and a gasket is arranged between the convex ring and the box body connecting seat, so that the pressure on the convex ring is reduced, and the service life of the shaft sleeve is prolonged.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
