304 and the hexagon-head of fastening screw 307, and lower bearing 306 is thrust ball bearing, to bear Axial load.The bottom of limit plate 304 has the lower accommodating cavity for accommodating lower bearing 306, and lower accommodating cavity is circular cavity and lower appearance Setting chamber is to be formed since the bottom surface of limit plate 304 upwardly toward the internal stretch of limit plate 304, lower bearing 306 it is outer straight Diameter is less than the overall diameter of upper bearing (metal) 305, and the interior diameter of lower bearing 306 is less than the circumscribed circle of the hexagon-head of fastening screw 307 Diameter, the diameter of lower accommodating cavity and the overall diameter size of lower bearing 306 are identical, and lower bearing 306 is not easy to fall off, good reliability, So that the bearing capacity of castor 3 is stronger.The hexagon-head of fastening screw 307 is located at the top of roller body 301, lower bearing 306 Overall diameter be greater than the diameter of the through-hole for allowing threaded shank to pass through being arranged on limit plate 304, mounting plate 303 and limit plate 304 it Between have gap, limit plate 304 is rotated relative to mounting plate 303, realize roller body 301 steering.Upper bearing (metal) 305, lower bearing 306 and fastening screw 307 are coaxial arrangement, and fastening screw 307 is located at the middle position of two supporting legs 302. The top surface of mounting plate 303 is equipped with the groove for accommodating nut 308, which is circular groove, and nut 308 is sheathed on fastening screw In 307 threaded shank and nut 308 and threaded shank are is threadedly coupled, nut 308 and be welded connecting with threaded shank.It again will fastening After screw 307 and nut 308 tighten fixation, nut 308 and fastening screw 307 are welded together, nut 308 and fastening screw 307 keep relatively fixed, and fastening screw 307 and nut 308 clamp limit plate 304, upper bearing (metal) 305, limit plate 304 and lower bearing 306, form integral structure；And mounting plate 303 is to be threadedly coupled with fastening screw 307, attaching nut 308, formation is similar to The effect of double nut, while nut 308 is welded and fixed with fastening screw 307, nut 308 is no longer able to rotate, prevent screw and Nut 308 loosens and associated components is caused to fall off, and provides safe fixed effect, enables castor 3 mobile in sterilizer body When stable movement is provided.

The utility model is exemplarily described in conjunction with attached drawing above.Obviously, the utility model implements not It is limited by aforesaid way.As long as the various unsubstantialities that the method concept and technical solution that use the utility model carry out Improvement；Or it is not improved, the above-mentioned conception and technical scheme of the utility model are directly applied into other occasions, at this Within the protection scope of utility model.
