Specific embodiment
With reference to embodiment, the technical solution of the utility model is described in further detail, but not structure
Any restrictions of pairs of the utility model.
Embodiment 1
As shown in Figs 1-4, a kind of flexible external member of curtain is additionally wrapped including female sub- rail 2 rail 1 and be arranged in female rail 1
Include hanging wheel 4；The lower part of female rail 1 and sub- rail 2 is equipped with notch 3；The lower part of female rail 1 is the slot positioned at female rail 1
A pair of of outer rail 11 of 3 two sides of mouth；The lower part of the sub- rail 2 is one cooperated with outer rail 11 positioned at 3 two sides of notch of sub- rail 2
To internal rail 21；11 edge of outer rail is equipped with the first sliding rail 12, and the edge of the internal rail 21 is equipped with the second sliding rail 22；It is described
Hanging wheel 4 on the first sliding rail 12 and the second sliding rail 22 along notch 3 slide；The top of the sub- rail 2 is the installation with peripheral hardware
The first groove of a pair 24 of code cooperation；The top two sides of the inner wall of female rail 1 are equipped with the branch for being used to support the first groove 24
Support member 15, the upper surface C that the distance of lower surface B of the upper wall A of first groove 24 to internal rail 21 is less than supporting element 15 are arrived
The distance of the upper surface D of outer rail 11.When such setting can guarantee that the upper wall A of the first groove 24 and supporting element 15 are contacted, institute
There are gaps between the lower surface B for the internal rail 21 stated and the upper surface D of outer rail.
In the process of running, hanging wheel 4 includes wheel body 41, hanging ring 42 and the connecting plate being arranged between wheel body 41 and hanging ring 42
43, wheel body 41 is that a pair sets up separately in the two sides of connecting plate 43, hanging wheel 4 in the process of running, wheel body 41 be with the first sliding rail 12 and
The contact of second sliding rail 22 is slided, and connecting plate 43 is mobile in notch 3.
Due to the first groove 24 upper wall A to internal rail 21 lower surface B distance be less than supporting element 15 upper surface C to outside
The distance of the upper surface D of rail 11, therefore have gap between the lower surface B of internal rail 21 and the upper surface D of outer rail 11, that is,
It says, in sub- 2 telescopic process of rail, the lower surface B of the internal rail 21 of sub- rail 2 will not be scratched, and in telescopic process, due to being branch
Support member 15 and the contact of the first groove 24, contact area is small, therefore is very easy to sliding.
After sliding in place, is cooperated by installation code and the first groove 24, be fixed on sub- rail 2 on the stationary plane of peripheral hardware.
Preferably, the top of female rail 1 is equipped with the second groove 13 with the installation code cooperation of peripheral hardware；It is sliding in place
Afterwards, cooperated by installation code and the second groove 13, be fixed on female rail 1 on the stationary plane of peripheral hardware.
In order to further decrease resistance to sliding, the upper wall A of first groove 24 is inclined-plane, first groove 24
Upper surface C of the upper wall A at a distance from the lower surface B of the position that supporting element 15 contacts to internal rail 21 less than supporting element 15 to outer rail
The distance of 11 upper surface D.Line contact is become by face contact between such first groove 24 and support, resistance is extremely
It is small.
In the present embodiment, first sliding rail 12 is equipped with bending recess portion 14 close to the side of internal rail 21；Described
The side of two sliding rails 22 is equipped with the positioning convex portion 23 extended in bending recess portion 14；When positioning convex portion 23 is withstood in bending recess portion 14
When, it can be to avoid sub- 2 double swerve of rail, while can also teetertotter to avoid sub- rail 2.
Preferably, the shape matching of the bending recess portion 14 and positioning convex portion 23；When bending recess portion 14 and positioning convex portion
When 23 snug fit, the upper surface of first sliding rail 12 and the upper surface of the second sliding rail 22 are concordant.
In the present embodiment, when bending recess portion 14 and positioning convex portion 23 and being closely fitted, first groove 24 it is upper
There are gaps between wall and supporter.
Can certainly be very close to each other, frictional resistance can be bigger in telescopic process if very close to each other.
In the present embodiment, the supporting element 15 is the support bar extended along the length direction of female rail 1.
In practical applications, it does not limit one and is set to support bar, or multiple support salient points of the linear alignment etc..
In above-mentioned curtain expansion rail, the inner wall of female rail 1 is equipped with sound-absorbing part 15.Similarly, the upper wall of sub- rail 2
Suction unit can be set.Suction unit can be integrally formed wavy surfaces, be also possible to acoustical cotton layer added etc..
Above-described embodiment is the preferable embodiment of the utility model, but the embodiments of the present invention is not by above-mentioned
The limitation of embodiment, it is made under other any spiritual essence and principles without departing from the utility model to change, modify, replacing
In generation, simplifies combination, should be equivalent substitute mode, is included within the protection scope of the utility model.
