Abstract
The invention discloses a kind of universal wheel perambulators comprising shell is connected in shell and can be around the wheel hub that shell rotates, and is installed on by shaft the rotating device of wheel hub；Universal wheel perambulator of the invention, because can all-direction rotation, carry out it is laborsaving；It is convenient to turn to, and has safety guard, therefore safe and reliable；And it is simple in construction, easy to disassemble and assemble.
Description
Technical field
The present invention relates to castors, are especially mounted in the universal wheel perambulator needed under frequent shift position equipment.
Background technique
Castor is common object, such as refrigerator, the washing machine of household electrical appliance, the small handcart of hotel's food delivery, the swivel chair etc. of household
It is required to use, after installing universal wheel perambulator, movement is more convenient.
Common universal wheel perambulator is generally divided into two big modules, steering module and rotating device module.The former makes castor
Can 360 ° rotated, so that mobile device is turned to any direction without a hitch；The latter moves mobile device freely
It is dynamic.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,
Need component more, such as shaft needs nut to fix, connection relationship is also very complicated, and processing increases therewith with assembly process, therefore
Higher cost.
Summary of the invention
The present 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 the following technical solution:
A kind of universal wheel perambulator is suitable for various mobile devices comprising shell is connected in shell and can rotate around shell
Wheel hub, and by the eccentrically mounted rotating device in wheel hub of shaft, spin is set between shell and wheel hub, and can smear
Lubricating oil, to help the relative rotation of shell and wheel hub.
Brake is arranged in the casing center, and the brake end is provided with convex block, and the brake protrudes into the wheel
The centre bore of hub, the convex block are stuck on the inner circle anchor ring of the wheel hub, and the wheel hub is connected in the shell.Due to described
Shell and wheel hub are that plastics are made, therefore access section friction is smaller, do not influence the two relative rotation.
The inner circle anchor ring of the shell and the outer circle anchor ring of the wheel hub respectively have the corresponding annular recess in position, the cunning
Spin is set in slot.Spin is steel ball, and quantity and size take the circumstances into consideration to be arranged.
Eccentric card slot is arranged in the inner circle anchor ring of the wheel hub, and the centre bore that the shaft passes through the rotating device is caught in institute
It states in the card slot on wheel hub.The shaft is steel, smaller with the friction of rotating device made of plastics, does not influence rotating device
Rolling.
The diameter of the shell and the wheel hub is greater than height, in flat.Therefore entire universal wheel perambulator device weight
The heart is lower.
The rotating device is cylindrical body with a central hole, and length is greater than diameter, therefore rotating device and ground are line
Contact, stress are more uniform.
The small body of card slot mouth is big, and oral area is slightly less than shaft diameter, and body portion is slightly larger than roller bearing diameter, therefore shaft is caught in card
It will not voluntarily fall off after slot.
The shell is equipped with centre bore, and the bracket of mobile device can protrude into the centre bore, by universal wheel baby of the invention
Youngster's vehicle is connected with mobile device.It may not possess centre bore, incite somebody to action this for example, by using bonding or any suitable way
Universal wheel perambulator and the mobile device of invention connect.
Universal wheel perambulator of the invention, structure is simple, and process and assemble easily goes and can all-directional rotation.

Specific embodiment
Specific embodiment is described with reference to the drawings.
A kind of universal wheel perambulator is suitable for various mobile devices comprising shell 1 is connected in shell 1 and can be around shell
The wheel hub 2 of 1 rotation, and by the eccentrically mounted rotating device 4 in wheel hub 2 of shaft 3, rolling is set between shell 1 and wheel hub 2
Ball 5, and can be with coating lubricating oil, to help the relative rotation of shell 1 and wheel hub 2.Brake 12 is arranged in 1 center of shell,
12 end of brake is provided with convex block 121, and the brake 12 protrudes into the centre bore 27 of the wheel hub 2, the convex block 121
It is stuck on the inner circle anchor ring 24 of the wheel hub 2, the wheel hub 2 is connected in the shell 1.The inner circle anchor ring 13 of the shell 1
Respectively there is the corresponding annular recess 131 and 231 in position with the outer circle anchor ring 23 of the wheel hub 2, set in the sliding slot 131 and 231
Set spin 5.Spin 5 is steel ball, and quantity and size take the circumstances into consideration to be arranged.
Eccentric card slot 22 is arranged in the inner circle anchor ring 24 of the wheel hub 2, and the shaft 3 passes through the center of the rotating device 4
Hole 42 is caught in the card slot 22 on the wheel hub 2.The diameter of the shell 1 and the wheel hub 2 is greater than height, in flat.Institute
41 shape of rotating device body of rotating device 4 is stated as cylinder, is provided with centre bore 42, the length of rotating device body 41 is greater than straight
Diameter.
22 mouthfuls of small bodies of the card slot are big, and oral area 221 is slightly less than 3 diameter of shaft, and body portion 222 is slightly larger than 3 diameter of shaft, therefore
Shaft 3 will not voluntarily fall off after being caught in card slot 22.
The shell 1 is equipped with centre bore 15, may not possess centre bore 15.
12 quantity of brake is 4, is mutually not attached to.Discrete brake 12 is convenient for brake 12 protruding into institute
It states in the centre bore 27 of wheel hub 2.
The shape of the shell 1 and wheel hub 2 is cylindric.
The shell 1 wraps around setting outer wall 11, and the wheel hub 2 wraps around setting side wall 21.
The deck 26 that 2 form the card slot 22 and 2 connection wheels are arranged in the inner circle anchor ring 24 of the wheel hub 2
The ribs 25 of hub side wall 21 and the deck 26.
The above disclosure is only a preferred embodiment of the invention, cannot limit the right of the present invention with this certainly
Range, therefore according to equivalent variations made by scope of the present invention patent, it is still within the scope of the present invention.
