Abstract

A universal roll ball comprises a round ball (2). A body (1) which is provided with a concave spherical surface (11) is arranged on the top portion. A cover plate (3) which enables part of the round ball (2) to be exposed and does not separate from the body (1) is arranged on the top portion of the body (1) in a detachable and covering mode. A holder (4) is arranged in the body (1), wherein the holder is matched with the concave spherical surface (11) and the bottom portion of the holder is provided with a hole cavity (42). Movable roll balls (5) are distributed inside the holder (4), and the round ball (2) can be placed on roll balls of the holder (4). Due to the fact that the holder is arranged inside the body, wherein the holder is matched with the concave spherical surface and the bottom portion of the holder is provided with the hole cavity, the round ball can enable dust which falls on the concave spherical surface to be accumulated inside the hole cavity because of roll of the round ball, and can enable the dust inside the concave spherical surface not to contact with the round ball, and therefore the phenomenon that the flexibility of the roll of the roll balls is influenced due to the fact that the previous dust is accumulated inside the concave spherical surface is avoided, and accordingly service life of the universal roll ball is prolonged.

Description

A kind of Universal caster

Technical field

The utility model relates to a kind of carriage for the production of the displacement of the product on the conveyor line, especially refers to a kind of Universal caster.

Background technology

Existing a kind of patent No. is that the Chinese utility model patent that the CN01253019.0 name is called " a kind of Universal caster " discloses a kind of structure, comprise that a ball, an inner chamber are body and one deck pellet layer that concave spherical surface can be placed ball, the outside of ball is a cover plate, be provided with the circular hole that partly stretches out for ball in the cover plate, cover plate comprises the plate face, is connected as a single entity with plate face edge and is shirt rim cylindraceous that cover plate is fixed on the body.Above-mentioned bottom, shirt rim have inwardly turn over into the bag edge.Also can be to be flush fit between the inboard of the sidepiece of body and shirt rim, make cover plate be difficult to break away from this.The Universal caster that this utility model provides, mobile flexible, good airproof performance are suitable for the purposes such as weight conveyance.Although but this utility model can well make being arranged at of ball rolling be unlikely in the cover plate to spin off by cover plate, but this ball is easy to make dust etc. to enter in the concave spherical surface when being used in the more place of dust, the rolling of ball and ball is obstructed, affect its alerting ability, reduce service life, so this structure awaits further to improve.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of design ingenious and can make the ball long-term work and keep rotating flexibly Universal caster for above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that adopts: this Universal caster, include ball, the top is provided with the body of a concave spherical surface, the dismountable type lid is equipped with and makes ball partly expose and not break away from the cover plate of body on described bodies top, it is characterized in that: also be provided with the retainer that and bottom suitable with concave spherical surface has vestibule in the described body, be distributed with movable ball in described retainer, described ball can place on the ball of retainer actively.

As improvement, be provided with breach on the described bodies top periphery wall, described cover plate bottom is extended the adapter plate suitable with the breach of body downwards, and described adapter plate is inserted in the breach and is fixed together with body.

As improvement, described breach is platform level ring, and described adapter plate is the annular cage plate suitable with platform level ring, and described annular cage plate cover inserts on the platform level ring and by fastener bolt and body and is fixed together.

As improvement, the downward projection of described cover plate is rounded, and institute's body is cylinder, and described cover plate downward projection Diameter of graphs is greater than cylindrical diameter.

As improvement, described body bottom is provided with for double-screw bolt or screw rod insert the screw hole that body is fixed on the fixture.

Compared with prior art, Universal caster of the present utility model has the retainer of vestibule by be provided with and bottom suitable with concave spherical surface in body, ball is arranged in the through hole of retainer, ball can be arranged on the ball rotationally, the design of this structure, can make ball fall to dust accumulation on the concave spherical surface in the vestibule of bottom because of rolling, the dust of falling in the concave spherical surface is no longer contacted with ball, thereby avoided the past because of dust accretions in concave spherical surface, and affect the alerting ability that ball rotates, the service life of then having improved Universal caster; And the utility model also can reduce the relative friction between ball by the position-limiting action of retainer to ball, makes rotation more flexible; The downward projection area of cover plate is arranged greater than the bodies top area again, cover plate can be held on the connected unit, make the easier for installation of this device; Body bottom is provided with screw hole in addition, if by bolt can be directly and bench board fix, make assembling more convenient.In sum, Universal caster of the present utility model is that a kind of design is ingenious, and ball rotates flexibly, and long service life, and the convenient product of installing are worthy of popularization.
