Description
Technical field
The utility model relates to window shade arrangements, more particularly to a kind of curtain rail.
Background technique
The curtain that existing market blade can turn to mostly uses rectilinear orbit, but as the improvement of people's living standards, room
Room corner is gradually increased using lunette, and it is wide that traditional rectilinear orbit can not match arc curtain runner.
Existing curtain rail is broadly divided into two classes, a kind of to pass through ballpoint device by linear rigid gear stick, makes
It being fixed on the accessory of track both ends with devices such as middle support sliding blocks, the sliding of ballpoint device is divided into the control of two steps with rotation and operates,
If such will be fabricated to arc line shaped, gear stick cannot be accurately consistent with track radian, and ballpoint device and middle support sliding block slide
Resistance is excessive when to segmental arc, smooth operation and can not use, window molded dimension it is excessive can not multistage splicing use；It is another kind of, it walks
The operation of pearl device is driven with rotation by single transmission power, and structural principle is belt-type transmission, first drives ballpoint device in track
Differential gear rotation, rear to drive first ballpoint device of operation end, which draws subsequent all ballpoint device fortune
Row.Such guide rail ballpoint device quantity is more, and power demand is big, transmission system is required it is very high, cost is high or service life compared with
Short, failure is more, is not sufficiently stable for 3 meters or more of window types durable.
In addition, tradition window curtain guide rail rubs the two sides inner wall of track there is also: ballpoint device at arc track, cause to hinder
Power increases, and operation has some setbacks；Gear stick and track radian have deviation that operation is caused to have some setbacks；Guideway transport is inconvenient to high building,
Only track section is dismantled, operation of the ballpoint device in junction is unsmooth；Single blade, which is blocked, causes other blades also can not
Rotation；Blade rotation angle wind-engaging influences the problems such as changing.
Utility model content
The utility model provides a kind of window for the shortcomings that structure of curtain rail is not suitable for lunette in the prior art
Gear stick and ballpoint device are separated, gear stick are fixed by curtain rail road, and the technical program is suitable for arc window, are reduced
