Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
Namely this Universal caster can be used for the carrying of weight in use, also directly can be fixed on bottom upholder and use.As shown in Figure 1, this Universal caster comprises round-bead seat 1, ball 2, pellet layer and housing 4 in spherical shape.
Round-bead seat 1 is provided with a recess, pellet layer and ball 2 to be all placed in recess and pellet layer between ball 2 and round-bead seat 1.Wherein, pellet layer is made up of the pellet 3 that some is spherical shape.Generally, pellet 3 and ball 2 all adopt metal or plastics to make.
Ball 2, round-bead seat 1 and pellet layer are all positioned at housing 4, and housing 4 top has the circular hole stretched out for ball 2 part.Specifically, as shown in Figure 2, housing 4 is in tubular, and natural housing 4 also can be square other shapes such as grade.Housing 4 top has annular connecting portion 4a protruding upward, and this annular connecting portion 4a tilts towards housing 4 axis direction.Annular connecting portion 4a axially runs through and has through hole two 4b, after this Universal caster assembles, ball 2 part stretches out through hole two 4b, and annular connecting portion 4a inside face matches with ball 2, reduces the impurity such as dust enter into housing 4 inside probability by through hole two 4b.
In addition, be also provided with an annular gasket 5 in housing 4, this annular gasket 5 outer peripheral face is resisted against on housing 4 inwall and lower surface is resisted against on round-bead seat 1, and annular gasket 5 to be blocked on recess and this annular gasket 5 inner peripheral surface and ball 2 mating shapes.Further illustrate, between ball 2 and annular gasket 5, there is gap, ball 2 is rotated more flexible.Annular gasket 5 inner peripheral surface is tapered, and the bearing of trend of the diameter of this inner peripheral surface annularly pad 5 upper surface reduces gradually, effectively reduces the amount of the impurity such as the dust entered in pellet layer; And annular gasket 5 can stop the pellet 3 in pellet layer, make pellet 3 be in suitable position, enable this Universal caster stable operation.
Be provided with liner 6 between housing 4 and annular gasket 5, liner 6 is made up of felt, reaches the effect of dedusting and water suction.
As shown in Figure 2, there is bottom housing 4 flange 4c, and this flange 4c and housing 4 sidepiece perpendicular.In the present embodiment, flange 4c and housing 4 are integrated and flange 4c have two symmetrically arranged screw hole 4d, by housing 4 and upholder being fixed with screw fit.
In the present embodiment, round-bead seat 1 is by being tightly fixed in housing 4.Round-bead seat 1 adopts metallic material and by machining, and what adopt mach object to be round-bead seat 1 can select the metallic material that some quality are harder, as iron, tombak etc., thus adds the ability of bearing gravity of university degree Universal caster.The size of prioritizing selection round-bead seat 1, slightly larger than the internal diameter of housing 4, utilizes the elasticity of metal sheet, is squeezed into by round-bead seat 1 in housing 4 and is fixed.
Because this Universal caster is in Long-Time Service process, round-bead seat 1 notched bottoms easily gathers certain liq, and this liquid can adsorb the dust being positioned at recess, offers through hole one 1a in round-bead seat 1 notched bottoms, liquid can be discharged from through hole one 1a, pellet 3 and ball 2 be rolled and keeps freely.
This Universal caster can be used for the carrying of weight, and a large amount of Universal casters can be evenly arranged on substrate during use, the weight that carry or workpiece pull weight above being directly placed on, more laborsaving when making operation.Nature, this Universal caster directly can also be fixed on bottom upholder and use.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
