Abstract
The utility model discloses a rail wheel device for an aluminium alloy door window. The utility model is composed of an outer support stand, an inner support stand, regulating screws, a rotating shaft and a track wheel, wherein, both side faces of the outer support stand are respectively provided with a groove which is communicated with two edges; both side faces of the inner support stand are respectively provided with a bar-shaped hole; the track wheel is arranged on the rotating shaft, both ends of the rotating shaft are arranged in the groove of the outer support stand through the bar-shaped hole of the inner support stand; the track wheel is composed of a shaft center tube, roller balls and an H-shaped wheel ring which is provided with a rubber ring with a groove. The utility model has the advantages of high support stand intensity, better dust prevention effect, low operation noise, stable operation, simple structure, low cost, convenient maintenance, easy wearing part replacement, etc.
Description
The utility model relates to a kind of rail wheel apparatus that is used for alumium alloy door and window.
At present, aluminium alloy door of the prior art window rail wheel apparatus, generally all be on its support arm, to leave through hole rotating shaft is installed, and its rail wheel directly adopts the plain bearing transformation of the way to form, therefore, existing aluminium alloy door window rail wheel apparatus ubiquity that the support arm structural strength is low, rail wheel cost height, the big shortcoming of noise when using, and since rotating shaft be installed on the through hole of support arm, its rotating shaft end exposes support arm, so the dustproof effect of its rotatable parts is poor.
The purpose of this utility model is: provide a kind of support arm intensity height, operating noise is little, cost is low, the dustproof effect of rotatable parts aluminium alloy door's window rail wheel apparatus preferably.
The utility model is to constitute like this: it comprises support arm (1), inner support (2), set screw (3), rail wheel (4), inner support (2) is contained in the support arm (1), set screw (3) is connected with inner support (2) by support arm (1), one groove that communicates with two edges (5) is arranged respectively in the two sides of support arm (1), in the two sides of inner support (2) bar hole (6) is arranged respectively, rail wheel (4) is contained in the rotating shaft (7), and the two ends of rotating shaft (7) are contained in the groove (5) of support arm (1) by the bar hole (6) of inner support (2); Rail wheel (4) is made up of axle center tube a, ball b, I shape wheel rim c, and a circle groove is arranged on the excircle of I shape wheel rim c, and the rubber ring (8) that has groove is housed in the groove of I shape wheel rim c.
The utility model compared with prior art, because the utility model is not opened shaft hole on support arm, therefore, its support intensity is apparently higher than support intensity of the prior art, in addition because rotating shaft of the present utility model is to be operated in the groove (5), its axle head does not expose, therefore its dustproof effect improves greatly, in addition, the utility model has adopted the I shape outer ring rail wheel that is with rubber ring, the little advantage of this rail wheel noise when having work, also have stable working, simple in structure, cheap advantage; Except aforementioned advantages, easy to maintenance, easy, the cheap advantage of replacing consumable accessory that the utility model also has.
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the left view of accompanying drawing 1;
Accompanying drawing 3 is that the K of accompanying drawing 1 is to view.
Embodiment of the present utility model: support arm (1), the size of inner support (2) is made into the same with prior art, inner support (2) is contained in the support arm (1), and be connected with inner support (2) by support arm (1) with set screw (3), when making support arm (1), suppress a groove that communicates with two edges (5) respectively in its two sides, this groove (5) is not only as the support slot of rotating shaft (7), but also be convenient to keep in repair time dismounting rail wheel (4), open a bar hole (6) respectively in the two sides of inner support (2), rail wheel (4) is contained in the rotating shaft (7), the two ends of rotating shaft (7) are contained in the groove (5) of support arm (1) by the bar hole (6) of inner support (2) respectively; Rail wheel (4) is made up of axle center tube a, ball b and the I shape wheel rim c that has a circle groove on its excircle, the component-assembled in addition of rail wheel (4) is assembled into one by the assemble method of plain bearing, assembles the back and puts rubber ring that has a groove (8) in the groove of its I shape wheel rim c.
Claims (2)
1, a kind of aluminium alloy door window rail wheel apparatus, it comprises support arm (1), inner support (2), set screw (3), rail wheel (4), inner support (2) is contained in the support arm (1), set screw (3) is connected with inner support (2) by support arm (1), it is characterized in that: a groove that communicates with two edges (5) is arranged respectively in the two sides of support arm (1), in the two sides of inner support (2) bar hole (6) is arranged respectively, rail wheel (4) is contained in the rotating shaft (7), and the two ends of rotating shaft (7) are contained in the groove (5) of support arm (1) by the bar hole (6) of inner support (2).
2, aluminium alloy door according to claim 1 window rail wheel apparatus, it is characterized in that: rail wheel (4) is made up of axle center tube a, ball b, I shape wheel rim c, one circle groove is arranged on the excircle of I shape wheel rim c, the rubber ring (8) that has groove is housed in the groove of I shape wheel rim c.
