Abstract

The utility model discloses an industrial caster wheel which comprises an upper vitreous disk, a lower vitreous disk and a caster wheel supporting frame arranged between the upper and the lower vitreous disks, wherein, roll balls are equally arranged among the upper vitreous disk, the lower vitreous disk and the caster wheel supporting frame, and the upper and the lower vitreous disks are fixed with the caster wheel supporting frame through a fixing piece, and are matched with the caster wheel supporting frame in a sliding mode; the fixing piece is connected with the upper vitreous disk or the lower vitreous disk to form a whole, grooves used for the roll balls to slide are respectively arranged among the upper vitreous disk, the lower vitreous disk and the caster wheel supporting frame. Because the utility model adopts the form that tha fixing piece is connected with the upper vitreous disk or the lower vitreous disk to form the whole, a gap existing between fixing piece and the upper and the lower vitreous disks can be effectively reduced, and the space which moves towards left and right is reduced when the upper and the lower vitreous disks are matched with the caster wheel supporting frame; thereby, the deflected phenomenon of the centerline of each of the upper and the lower vitreous disks is generated with difficulty, flexible rotation of the upper and the lower vitreous disks is realized, and a ball clamping phenomenon is completely stopped.

Description

A kind of industrial castor

Technical field

The utility model relates to five metals and makes the field, is a kind of industrial castor specifically.

Background technology

At present, industrial castor in the five metals manufacturing field is generally by last, following glass dish and trundle bracket are formed, on, be respectively arranged with ball between following glass dish and trundle bracket, and then connecting element is fixed up, make, following glass dish can rotate on trundle bracket under the ball effect, but restriction by existing castor technology, connecting element and last, all there is big gap in following glass dish, thereby on, all there is the space of sway in following glass dish when cooperating with trundle bracket, on, the line of centers of following glass dish is easy to generate and departs from, make, following glass dish rotates dumb, even card pearl phenomenon occurs, and this is one sorry greatly really.

Summary of the invention

The purpose of this utility model is the shortcoming that overcomes above-mentioned prior art, provides a kind of line of centers of upper and lower glass dish to be difficult for producing the industrial castor that departs from and upper and lower glass dish is rotated flexibly.

The utility model can be realized in the following manner:

A kind of industrial castor, comprise glass dish, following glass dish and caster wheel support between the glass dish up and down is set, be provided with ball between last glass dish, following glass dish and trundle bracket, the glass dish is fixed by a connecting element and trundle bracket up and down, and with the trundle bracket bearing fit, this connecting element and last glass dish or following glass dish link into an integrated entity.

Be respectively equipped with between last glass dish, following glass dish and trundle bracket and be used for the groove that ball slides.

The utility model compared with prior art has following advantage:

The utility model is owing to adopted connecting element and the form of last glass dish or following linking into an integrated entity of glass dish, thereby can reduce gap between connecting element and the upper and lower glass dish effectively, the space of sway when also having reduced upper and lower glass dish and cooperating with trundle bracket, thereby the line of centers that makes upper and lower glass dish is not easy to produce off-set phenomenon, realize that upper and lower glass dish rotates flexibly, has stopped card pearl phenomenon completely effectively.

Accompanying drawing 1 is a prior art STRUCTURE DECOMPOSITION generalized section;

Accompanying drawing 2 is the utility model STRUCTURE DECOMPOSITION generalized section;

Accompanying drawing 3 is accompanying drawing 2 textural association generalized sections;

Accompanying drawing 4 is that another structure of the utility model is decomposed generalized section.

The specific embodiment

Come the utility model is further described below in conjunction with accompanying drawing:

Accompanying drawing 1 is a prior art STRUCTURE DECOMPOSITION generalized section.

Shown in accompanying drawing 2, accompanying drawing 3, the utility model industrial castor comprises glass dish 1, following glass dish 2 and caster wheel support 3 between the glass dish up and down is set, last glass dish 1, following

glass dish

2 and 3 of trundle brackets are provided with ball 4, the glass dish is fixed with trundle bracket by a connecting element 5 up and down, and with the trundle bracket bearing fit, this connecting element 5 links into an integrated entity with last glass dish 1.

Last glass dish 1, following

glass dish

2 and 3 of trundle brackets are respectively equipped with and are used for the groove that ball 4 slides.

Only enumerated the connection mode that connecting element and last glass dish link into an integrated entity in the present embodiment; the connection mode that can certainly adopt connecting element and following glass dish to be connected in one; as shown in Figure 4; moreover; the shape of trundle bracket the and up and down shape of glass dish is can many formulas various, thereby change trundle bracket and the shape of the glass dish protection domain of the present utility model that also falls up and down.

Claims

1, a kind of industrial castor, comprise glass dish (1), following glass dish (2) and caster wheel support (3) between the glass dish up and down is set, be provided with ball (4) between last glass dish (1), following glass dish (2) and trundle bracket (3), the glass dish is fixed by a connecting element (5) and trundle bracket up and down, and with the trundle bracket bearing fit, it is characterized in that: this connecting element and last glass dish (1) or following glass dish (2) link into an integrated entity.

2, industrial castor according to claim 1 is characterized in that: go up between glass dish (1), following glass dish (2) and trundle bracket (3) and be respectively equipped with the groove that is used for ball (4) slip.
