Abstract
A multifunctional universal wheel belongs to a rolling device for moving heavy objects and comprises a wheel carrier and a rolling body, wherein the wheel carrier is a disc, the upper end surface of the disc is provided with a fixed shaft, the lower end surface of the disc is provided with a protruding circular ring, the bottom of an inner cavity of the circular ring is provided with 3-6 limiting grooves, and the outer edge of the circular ring is provided with a stop sleeve; the rolling bodies are a large steel ball and 3-6 small steel balls, the small steel balls are positioned in the limiting grooves, and part of spherical surfaces of the large steel balls are exposed out of the middle holes of the stop sleeves. The outer edge of the stopping sleeve is provided with a rotary sleeve in threaded connection with the stopping sleeve. The utility model is used for transport, the removal of heavy object or furniture, the atress is reasonable balanced, the friction position is few, rotates nimble reliable, and is not fragile and the card is dead, long service life, when need not to roll moreover, can lock.
Description
Technical field
The utility model relates to a kind of tourelle of moving heavy object, particularly the cardan wheel that mainly is made of wheel carrier and rolling body.
Background technology
In the workshop, the bottom of furniture such as heavy object such as used cargo storage frame, goods trolley or the operator's station in warehouse, harbour, tool chest and sofa, chair usually needs to load onto cardan wheel, so that carrying, move and adjust the position.Existing cardan wheel generally is fixed on the wheel carrier with horizontal shaft by roller or spheroid, again wheel carrier is fixed on the object bottom by vertical axis, composite rotating by horizontal shaft and vertical axis realizes universal rotation, this structure is because the friction position is many, there is moment of resistance, often damage easily and stuck, use dumbly, and can't lock when not needing to roll.
The utility model content
The technical problems to be solved in the utility model provide a kind of stressed rationally, rotate flexibly, good, the long service life of stationarity, and the multifunctional universal that can lock wheel.
The technical solution of the utility model is: the multifunctional universal wheel comprises wheel carrier and rolling body, improvements are that described wheel carrier is the disk that the upper end has anchor shaft, there is the annulus of a projection disk lower surface, the annulus intracavity bottom has 3～6 roads along circumferential uniform and position-limited trough radially, with holes ending overlapped in the middle of the annulus outer rim was provided with, described rolling body is a big steel ball and 3～6 small balls, every small ball is positioned at position-limited trough one, big steel ball contacts with small ball, and its spherical calotte exposes the interstitial hole that ends cover.
Further scheme is: big steel ball is centered close on the axis of wheel carrier anchor shaft; Angle α=30 of the line at small ball center and big steel ball center and horizontal surface °～45 °; The outer rim of ending cover is provided with the rotation set that is threaded with it; Be threaded on the wheel carrier anchor shaft.
Adopt above technical scheme, the utility model is realized the rotation of cardan wheel any direction by contact between the large and small steel ball and rolling, the friction position is few, do not produce moment of resistance, and steel ball all have spacing by the wheel carrier line of centers suffered making a concerted effort, stress equalization is reasonable, therefore the gap is even, rotates very flexibly, and stationarity is good, be not easy damage and stuck, long service life; When weight fixedly need not to roll, adjust rotation set, cardan wheel can be locked motionless.Be threaded on the wheel carrier anchor shaft, be convenient to install, dismantle, use more convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is along A-A place section-drawing (removing steel ball) among Fig. 1.
The specific embodiment
Consult accompanying drawing, there is the annulus of a projection disk 2 lower surfaces that have anchor shaft 1, the annulus intracavity bottom has the uniform position-limited trough in 4 roads 7, a small ball 3 is arranged in the per pass position-limited trough, the annulus outer rim is provided with only overlaps 6 and the rotation set 5 that is threaded with it, big steel ball 4 contacts with small ball, and coaxial with anchor shaft, and its spherical calotte exposes outside the interstitial hole that ends cover.The angle α of small ball center and the big steel ball line of centres and horizontal surface gets 40 °.Outside thread is arranged on the anchor shaft.
Claims (5)
