Abstract
The utility model relates to an assembly pulley used for a window curtain guide rail, which comprises a supporting base, a shaft sleeve which is provided on the upper part of a wheel supporting base and has a shaft hole and two pulleys which are positioned on two sides of the shaft sleeve and are supported by a shaft; the shaft passes through and is positioned on the shaft hole. The utility model is characterized in that the upper part of the wheel supporting base is provided with an arch-shaped top ring being higher than the shaft sleeve. With the arch-shaped top ring provided on the upper part of the wheel supporting base and the two assembly groups provided on the side of a wheel, the strength of the utility model and reliability of the installation of the utility model are both improved while the whole parts of the utility model has the advantages of flexible sliding, convenience and aesthetic outline; meanwhile, the mono-assembly of the utility model omits the assembly process, lowers the production cost and provides the new proposal for the production of the window curtain guide rail.
Description
Technical field
The utility model relates to a kind of curtain rail, particularly a kind of curtain rail assembly pulley.
Background technology
Existing curtain rail constitutes by a pair of pulley and the lower end annulus with the metal making is set on the wheeling support mostly with assembly pulley, this structure exists because of ring body and is U type cavity design and connects the outer shaft of pulley too thin, under the effect of different cloth matter and external force, cause the damage of wheeling support because of intensity is relatively poor, in addition pulley mostly be with the plastic shaping manufacturing or in plastic wheel cover system one rubber ring method, the former is installed in and easily produces the friction sound in the guide rail, and the latter installs the back and separates with cushion rubber because of stressed or other factors cause wheel.
Summary of the invention
The purpose of this utility model is to provide a kind of reasonable in design, durable curtain rail assembly pulley that has at above-mentioned existing problems, simultaneously associated pulley also have overall structure good, rotate flexible, quiet advantage.
A kind of curtain rail assembly pulley comprises wheeling support, is arranged on the axle sleeve in tape spool hole, wheeling support top and is arranged in the axle sleeve both sides and by two pulley that support that is placed through axis hole, described wheeling support top is provided with the arch apical ring that exceeds axle sleeve.
The utility model is owing to two assembly pulleys of arch apical ring set on wheeling support top and wheel side, under the prerequisite that is improved aspect the reliability of intensity and installation, have the characteristics flexible, convenient, good looking appearance of sliding after making the preparation of global facility and curtain rail again, the one-body molded assembly process that saved of while, reduced production cost, for the production of curtain rail provides a kind of new scheme.
Below in conjunction with accompanying drawing the utility model is further described:
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the front view of wheeling support;
Fig. 3 is the left view of wheeling support.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the utility model comprise wheeling support 2, be arranged on the axle sleeve 3 in tape spool hole, wheeling support 2 top 31 and be arranged in axle sleeve 3 both sides and by two pulleys 1 of the axle supporting that is placed through axis hole.Described two pulleys 1 are flexible connection with wheeling support 2, and it can be to use rivet, perhaps uses pin, also the method for attachment of other any axle sleeve type.For strengthening the rigidity on wheeling support 2 tops, be provided with the arch apical ring 4 that exceeds axle sleeve 3 on wheeling support 2 tops.Described arch apical ring 4 thickness are slightly narrower than guide rail chute opening part width, and the ring heights of roofs is close with pulley wheel face height.Described wheeling support 2 ring sides are provided with inverted U ring flat-plate 21, can not be out of shape when stressed for making ring flat-plate 21, are connected with gusset 22 in ring flat-plate 21, are the stationarity that guarantees to slide in guide rail, and gusset 22 both sides are provided with limited post 23.Described wheeling support 2 bottoms are provided with for the ring body 5 that hangs curtain, and above-mentioned ring body 5 sections are cylindrical, and circumscribed linking to each other are encircled with ring flat-plate 21 edges of described wheeling support 2 in both sides, and top circular arc and gusset 22 join.The wheel face 12 of above-mentioned pulley 1 wheel body 11 and be coated with the clad 13 of anti-noise effect on every side.Above-mentioned clad 13 adopts elastomeric material, annotates one-body molded on wheel body 11 by glue.Have some apertures 14 on the above-mentioned wheel body 11), the dual-side of described clad 13 connects by the adhesive tape 15 that is packed into also moulding in the aperture 14 when glue is annotated.The manufacturing that is formed in one of the above-mentioned wheeling support of being made up of each connected mode 2 both can be adopted the injection moulding processing method, also can adopt the non-ferrous metal pressure casting method, all-in-one-piece structure and reasonably structure makes wheeling support 2 have excellent mechanical intensity.
