Description
Technical field
The present invention relates to castor, especially installed in the universal wheel perambulator needed under the normal shift position equipment of Jing.
Background technology
Castor is that conventional thing, the refrigerator of such as household electrical appliance, washing machine, the small handcart of hotel's food delivery, swivel chair of family expenses etc. are required to use, and after installing universal wheel perambulator, movement is convenient.
Common universal wheel perambulator is generally divided into two big modules, steering module and whirligig module.The former make castor can 360 ° rotated, allow mobile device to turn to any direction without a hitch；The latter moves freely mobile device.Prior art castor center of gravity is higher, and wheel seat is amesiality, therefore Moment is larger, is easily damaged；Structure is loaded down with trivial details, needs component many, and such as rotating shaft needs nut to fix, and annexation is also very complicated, and processing increases therewith with assembly process, therefore relatively costly.
The content of the invention
The invention provides a kind of center of gravity is low, structure is very simple, can all-directional rotation universal wheel perambulator.
The present invention provides following technical scheme：
A kind of universal wheel perambulator, suitable for various mobile devices, its wheel hub for including housing, being connected in housing and can rotate around housing, and by the eccentrically mounted whirligig in wheel hub of rotating shaft, spin is set between housing and wheel hub, and can be with coating lubricating oil, to help rotating against for housing and wheel hub.
The casing center arranges brake, and the brake end is provided with projection, and the brake stretches into the centre bore of the wheel hub, and the projection is stuck on the inner circle anchor ring of the wheel hub, and the wheel hub is connected in into the housing.Make because the housing and wheel hub are plastics, therefore access section friction is less, does not affect both to rotate against.
The inner circle anchor ring of the housing and the cylindrical anchor ring of the wheel hub respectively have the corresponding annular recess in position, and in the chute spin is arranged.Spin is steel ball, and its quantity and size are arranged as one sees fit.
The inner circle anchor ring of the wheel hub arranges eccentric draw-in groove, and the rotating shaft is snapped in the draw-in groove on the wheel hub through the centre bore of the whirligig.The rotating shaft is steel, less with the friction of whirligig made by plastics, does not affect the rolling of whirligig.
The housing and the wheel hub with diameter greater than height, in flat.Therefore whole universal wheel perambulator device center of gravity is relatively low.
The whirligig is the cylinder with centre bore, and length is more than diameter, therefore whirligig and ground are linear contact lay, and stress is more uniformly distributed.
The little body of the card slot mouth is big, and oral area is slightly less than shaft diameter, and body portion is slightly larger than roller bearing diameter, thus rotating shaft snap in will not self falling after draw-in groove.
The housing is provided with centre bore, and the support of mobile device can stretch into the centre bore, and the universal wheel perambulator of the present invention is coupled together with mobile device.Can not also possess centre bore, couple together the universal wheel perambulator of the present invention with mobile device for example with bonding or any suitable mode.
The universal wheel perambulator of the present invention, simple structure, process and assemble is easily gone and can all-directional rotation.

Specific embodiment
Specific embodiment is described with reference to the drawings.
A kind of universal wheel perambulator, suitable for various mobile devices, it includes housing 1, is connected in housing 1 and can be around the wheel hub 2 of the rotation of housing 1, and by the eccentrically mounted whirligig 4 in wheel hub 2 of rotating shaft 3, spin 5 is set between housing 1 and wheel hub 2, and can be with coating lubricating oil, to help rotating against for housing 1 and wheel hub 2.The centrally disposed brake 12 of the housing 1, the end of the brake 12 is provided with projection 121, and the brake 12 stretches into the centre bore 27 of the wheel hub 2, and the projection 121 is stuck on the inner circle anchor ring 24 of the wheel hub 2, and the wheel hub 2 is connected in into the housing 1.The inner circle anchor ring 13 of the housing 1 and the cylindrical anchor ring 23 of the wheel hub 2 respectively have the corresponding annular recess 131 and 231 in position, and spin 5 is arranged in the chute 131 and 231.Spin 5 is steel ball, and its quantity and size are arranged as one sees fit.
The inner circle anchor ring 24 of the wheel hub 2 arranges eccentric draw-in groove 22, and the rotating shaft 3 is snapped in the draw-in groove 22 on the wheel hub 2 through the centre bore 42 of the whirligig 4.The housing 1 and the wheel hub 2 with diameter greater than height, in flat.The profile of whirligig body 41 of the whirligig 4 is cylinder, is provided with centre bore 42, and the length of whirligig body 41 is more than diameter.
22 mouthfuls of little bodies of the draw-in groove are big, and oral area 221 is slightly less than the diameter of rotating shaft 3, and body portion 222 is slightly larger than the diameter of rotating shaft 3, thus rotating shaft 3 snap in will not self falling after draw-in groove 22.
The housing 1 is provided with centre bore 15, it is also possible to do not possess centre bore 15.
The quantity of the brake 12 is 4, is mutually not attached to.Discrete brake 12 is easy to brake 12 be stretched into the centre bore 27 of the wheel hub 2.
The profile of the housing 1 and wheel hub 2 is cylindric.
The housing 1 wraps around setting outer wall 11, and the wheel hub 2 wraps around setting side wall 21.
The inner circle anchor ring 24 of the wheel hub 2 arranges 2 decks 26 for forming the draw-in groove 22, and 2 ribs 25 for connecting the wheelboss side wall 21 and the deck 26.
Above disclosed is only the preferred embodiments of the present invention, can not limit the interest field of the present invention, therefore the equivalent variations made according to scope of the present invention patent with this certainly, still belongs to the scope that the present invention is covered.
