Further improvement of the utility model is: this apparatus structure is simple, and is easy to operate, safer, long service life, motion flexibly, without the jam phenomenon.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to scheme drawing;
Number in the figure: ear is drawn with back-up ring, 3-bearing, 4-axletree, 5-roller, 6-roller shaft, 7-shaft block ring, 8-turning rolls, 9-disk, 10-coaster body, 11-set of wheels, 12-in 1-wheel, 2-hole.
The specific embodiment:
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the utility model, does not consist of the restriction to the utility model protection domain.
Show a kind of embodiment of a kind of coaster of the utility model such as Fig. 1 and Fig. 2, comprise coaster body 10, be arranged with four set of wheels 11 in coaster body 10 bottoms, be provided with in the front portion of coaster body 10 front end wheels 1 and draw ear 12, each set of wheels 11 comprises the wheel 1 that arranges about two, each wheel 1 is connected with coaster body 10 by axletree 4, between wheel 1 and axletree 4, be provided with bearing 3, end in bearing 3 outsides is provided with hole back-up ring 2, the other end is provided with shaft block ring 7, between two axletrees 4, be connected with roller shaft 6, be provided with roller 5 at roller shaft 6, roller shaft 6 and roller 5 are located on the turning rolls 8, are provided with disk 9 between axletree 4 and coaster body 10.
The utility model is simple in structure, and is easy to operate, safer, long service life, and without card group phenomenon, motion is more flexible, drive lifting piece up-and-down movement, can walk in orbit.
