Abstract

The utility model relates to a curtain rail comprising a rail body, a rolling component, a handle for hanging curtains. The rail body is a tubular section bar whose lower part is provided with a longitudinal slot; two rollers are connected into integration by a rotary shaft; the handle for hanging curtains is extended out of the rail body and is movably connected to a rolling shaft; the outer sides of the roller form a hemispherical shape or a semi-ellipsoid shape. In the process of opening or closing the curtain, both the contact of the bottoms of two rollers and the inner surface of the rail body and the contact of the outer sides of the rollers and the inner surface of the rail body have a better rolling performance. The tubular section bar is used as the rail body, which can prevent dirt such as fly ash from bonding on the rail. The utility model is provided with fixing components corresponding to the appearance of the section bar, with convenient installation and material saving.

Description

Curtain rail

The utility model relates to the curtain rail field, particularly a kind of curtain rail of roller type.

At present, the guide rail of roller type curtain rail mostly is " worker " font greatly, drives the switching of the curtain that hangs by two side wheels.This type of guide rail is an Open architecture, easily is sticky with by dirts such as dust and influences the flexibility of rolling.Special in the switching process of curtain, be easy to cause the card rail because of beating or swinging.The curtain rail that Chinese patent discloses a kind of ball-type No. 95202210.9, its rolling assembly are to be located at the every row of the row of one to two in the tubular support to contain the free ball that 2～3 parts are protruded outside it and are in contact with one another side by side.The consumption of ball is big, and the manufacturing of tubular support is also comparatively complicated, makes production cost higher.Tubular support between two adjacent rolling assemblies also can be stuck in the course of the work, and this kind guide rail is not very convenient in installation process yet.

The purpose of this utility model is: provide a kind of simple in structure, roll and flexibly, not block rail, low, the easy-to-install curtain rail of cost.

In order to achieve the above object, the utility model is achieved through the following technical solutions:

A kind of curtain rail comprises guide rail, rolling assembly, curtain handle; Guide rail is the tubulose section bar that the bottom is provided with vertical fluting, and rotating shaft fuses two rollers, and the curtain handle that stretches out guide rail is movably connected on the roller bearing, and the profile of two rollers is corresponding with guide rail middle orbit surface.

The outside of roller is hemispherical or semielliptical shape.

The groove width of guide rail is less than single roller and curtain handle width sum, greater than the width of curtain handle.

Guide rail is semicircle tubing, and is furnished with and the corresponding fixture of tubing profile.

The curtain handle is provided with projection.

Described guide rail, rolling assembly, roller, roller bearing, curtain handle, fixture are made by plastics.

As curtain rail described in the utility model, in the draw-back curtain process, contact with the inner surface of guide rail no matter two rollers are bottoms, or the inner surface of the outside of roller and guide rail all has good rolling characteristics.

Advantage of the present utility model is: owing to adopt the tubulose section bar of band fluting to make guide rail, can prevent that dirt such as dust is sticky with track; The outside of roller is hemispherical or semielliptical shape, no matter be that the bottom of roller or the outside contact with the inner surface of guide rail and all to have good rolling characteristics.The groove width of guide rail is less than single roller and curtain handle width sum, greater than the width of curtain handle, makes roller can not block rail and the curtain handle can move freely.Adopt semicircle tubing, and be furnished with and the corresponding fixture of tubing profile, economical with materials can conveniently be installed.

For clearer explanation the utility model, be elaborated below in conjunction with accompanying drawing:

As shown in Figure 1, guide rail 1 is provided with the semicircle tubulose section bar of vertical fluting for the bottom, and rotating shaft 3 fuses two halves spherical roller 2, and the hanging hole 6 that stretches out the curtain handle 4 of guide rail is movably connected on the roller bearing, is provided with the hanging hole 5 that is used to hang curtain in curtain handle bottom.The groove width of guide rail is less than single roller and curtain handle width sum, greater than the width of curtain handle.In curtain switching process, contact with the inner surface of guide rail no matter two rollers are bottoms, or the inner surface of the outside of roller and guide rail all has good rolling characteristics.The curtain handle is provided with projection 7, can prevent that the curtain handle is slipped in the guide rail.

Shown in Fig. 2 A, Fig. 2 B is fixture of the present utility model, and guide rail can be installed easily with fixture.

Fig. 3 A, Fig. 3 B, Fig. 3 C are the schematic diagrames of multi-form rolling assembly of the present utility model.They can both roll when rolling assembly departs from the center flexibly.

Fig. 4 A, Fig. 4 B have provided the guide rail of different cross section shape of the present utility model.Certainly on guide rail, also fixing hole can be set directly.
