4) the curtain edge is sharp and is easy to hurt people.
SUMMERY OF THE UTILITY MODEL
Based on above, the utility model provides a no stay cord day night curtain overcomes not enough that traditional day night curtain structure exists, improves usability, security and the functional of (window) curtain.
In order to achieve the purpose, the utility model adopts the following technical proposal:
the pull rope-free day and night curtain comprises a night curtain for shading, a non-shading or semi-shading day curtain, an upper rail, a first lower rail and a second lower rail, wherein the upper rail, the first lower rail and the second lower rail are sequentially arranged in an up-down parallel mode, two spring systems and two guide wheel seats respectively located at two ends of the spring systems are arranged on the upper rail, two rotating wheels are arranged on the guide wheel seats, the rotating wheels on one guide wheel seat and the rotating wheels on the other guide wheel seat are used in a group, pull ropes are led out from two ends of each spring system respectively, one group of pull ropes are connected with the first lower rail after passing through one group of rotating wheels, the other group of pull ropes are connected with the second lower rail after passing through the other group of rotating wheels, the day curtain and the night curtain are correspondingly located between the upper rail and the first lower rail and between the first lower rail and the second lower rail, and the folding and unfolding of the day curtain and the night curtain are controlled by changing the distance between the.
In particular, the sun curtain adopts transparent or semitransparent yarns, and the pull rope passes through the yarn body from top to bottom and back and forth.
Particularly, the night curtain adopts non-woven fabrics, and the pull rope passes through the cloth body from top to bottom and back and forth.
In particular, the pulling force of the two spring systems on the corresponding pull ropes is respectively equal to the gravity of the sun curtain and the corresponding lower rail and the gravity of the night curtain and the corresponding lower rail.
Particularly, two ends of the upper rail, the first lower rail and the second lower rail are respectively provided with a shielding end head.
In particular, the upper rail is provided with a mounting bracket for fixing.
In particular, a handle is arranged on the first lower rail and/or the second lower rail.
To sum up, the beneficial effects of the utility model are that, compared with the prior art, the stay cord-free day night curtain can realize adjusting day curtain and night curtain receipts, exhibition wantonly through the structure of spring system with built-in stay cord, through two lower rail actions of direct drive, has saved exerted stay cord, and the appearance is more pleasing to the eye, and the structure is better, and the operation is more convenient, stable, has satisfied the switching demand of day curtain, night curtain, and security, functional stronger.
Drawings
Fig. 1 is a schematic structural view of a stay-cord-free day and night curtain provided by an embodiment of the present invention;
fig. 2 is a top view of a cordless day and night curtain according to an embodiment of the present invention.
Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
Referring to fig. 1 and 2, the present embodiment provides a cordless day/night curtain, which includes a day curtain 1 that does not shade light or partly shades light, a night curtain 2 for shading light, and an upper rail 3, a first lower rail 4, and a second lower rail 5 that are arranged in parallel in sequence from top to bottom. In this embodiment, the day curtain 1 is disposed on the upper half portion, and the night curtain 2 is disposed on the lower half portion, and may be inverted, and the size is automatically adjusted as needed.
The upper rail 3 is provided with two spring systems 6 and two guide wheel seats 7 respectively positioned at two ends of the spring systems 6, the guide wheel seats 7 are provided with two rotating wheels 8, and the rotating wheel 8 on one guide wheel seat 7 and the rotating wheel 8 on the other guide wheel seat 7 are used in groups. Two spring system 6 pile up from top to bottom, set up the lift dynamics through spring system 6, provide the ability of hovering, control curtain body left and right sides through the runner 8 at both ends and balance and lead.
