Abstract
The utility model relates to a pulley used for window wheels of aluminum alloy doors and windows, comprising a copper wheel and a wheel sleeve; wherein, a core hole which can punch a core shaft is arranged at the position of the axis of the copper wheel; a concave ring groove is arranged on the radial direction outer surface of the copper wheel; plastic with moderate hardness is adopted for the wheel sleeve and is integrally injected on the ring groove surface of the copper wheel as as to form a concave wheel groove. Due to adoption of the structure that the copper wheel and the plastic wheel sleeve with moderate hardness are combined, through contacting of the plastic wheel sleeve and a guide raill, the utility model has the advantages of effective reduction of sliding resistance, reduction or elimination of sliding noise, protection of the copper wheel without abrasion, great prolonging of service life, simple structure, ingenious conception and strong practicability.
Description
The utility model relates to a kind of pulley, the pulley that particularly a kind of alumium alloy door and window curtain runner is used.
The pulley of using in the existing alumium alloy door and window curtain runner generally adopts zinc, iron or galvanized iron or moulds firmly and is made into integration, because friction was loud when pulley rotated on metal sash guide very stiff and demandingly, send bigger noise easily, influence the quiet of surrounding environment, and after pulley used a period of time, it was bigger to wear and tear, and the balance of rail is walked in influence, occur the phenomenon of beat even card rail when causing walking rail, make troubles to use.And since its core hole of pulley that zinc, iron or galvanized iron or mould is firmly made also can occur wearing and tearing after a period of time is used in the position with contacting of metal mandrel, and frictional resistance was big when it rolled, the flexibility that influences pulley rolling reaches and occurs beat easily and make its application life short, thereby need bearing or copper sheathing to be set in its core hole and mandrel junction, to reduce its resistance to rolling and to reduce the wastage, make its complex structure so again, the complex manufacturing difficulty is big, assembling is inconvenient, and cost improves.
The purpose of this utility model provides a kind ofly can effectively reduce slip noise, walk rail steadily, the alumium alloy door and window curtain runner pulley of long service life.
The utility model comprises copper wheel, wheel cover, and wherein the copper wheel shaft core position is provided with the core hole that can place mandrel, and its radially-outer surface is provided with interior concave ring groove, and the wheel cover adopts neither too hard, nor too soft plastic cement one to be injection-moulded in the ring groove surface of copper wheel and to be formed with the indent race.
The utility model is owing to adopt copper wheel and neither too hard, nor too soft plastic roller cover structure combining, the copper wheel body that adopts effectively lowers the frictional resistance between mandrel and the core hole, reduce the wearing and tearing in core hole, it is flexible, reliable to guarantee that fully pulley rotates, effectively guarantee when pulley is walked on guide rail more stable and flexible, avoid occurring the phenomenon of beat and card rail, and prolong its application life.When pulley slides on the hard guide rail simultaneously; contact with guide rail by the wheel cover; frictional resistance when effectively lowering the pulley slip; wearing and tearing when reducing its slip; thereby effectively protect the copper wheel body not frayed; prolong its application life greatly; and effectively reduce or eliminate the noise that produces when pulley slides; keep the quiet of environment; and neither too hard, nor too soft wheel cover cooperates compacter with guide supporting; more steady when making pulley walk rail, phenomenons such as the beat that occurs when avoiding away rail, card rail are used more convenient simple.And the utility model is simple in structure, be skillfully constructed, and is practical strong, can be widely used in the curtain runner of various alumium alloy door and window.
Describe basic structure of the present utility model and principle in detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left TV structure schematic diagram of Fig. 1.
As Fig. 1-shown in Figure 2, the utility model comprises copper wheel 1, wheel cover 2, wherein copper wheel 1 shaft core position is provided with the core hole 11 that can place mandrel, and its radially-outer surface is provided with interior concave ring groove 12, and wheel cover 2 adopts neither too hard, nor too soft plastic cement one to be injection-moulded in annular groove 12 surfaces of copper wheel 1 and is formed with indent race 21.Be fixed on the copper wheel 1 for effectively taking turns cover 2, the above-mentioned cover 2 of taking turns adopts neither too hard, nor too soft plastic cement one to be injection-moulded in annular groove 12 surfaces of copper wheel 1 and the end position of copper wheel 1 two sides, is formed with the button limit 22 of certain width in copper wheel 1 two sides.Thereby make wheel cover 2 on the basis that effectively is nested with on annular groove 12 surfaces of copper wheel 1, wheel cover 2 be buckled in the two sides of copper wheel 1, make wheel cover 2 and copper wheel 1, further strengthen it and walk the steadily reliable of rail in conjunction with tightr, firm.Reliable and stable when further guaranteeing that pulley walk on guide rail avoids it the phenomenon of beat even card rail to occur, effectively increase the contact surface in mandrel and pulley core hole, and minimizing curtain runner support is to the influence of pulley.The position that above-mentioned copper wheel is positioned at the core hole extends axially formation boss 13 to both sides.
