Therefore, a purpose of the present utility model provides a kind of sun blind with horizontal wide and length adjustment, makes these sun blind can adapt to less window and installs and uses, and have the bigger scope of application.

Another purpose of the present utility model provides a kind of when regulating horizontal wide and length, as long as sky rail and underbeam are shortened do retraction, directly stay cord is pulled down the sun blind that the underbeam rising is got final product simultaneously, have the Practical Benefit of using simple and easy quick adjustment to install with adjusting length and width function.

The sun blind of the regulated length and width that the utility model proposes, mainly contain and be contained in day adjusting device of rail positioned internal, restrict in stay cord and ladder that the sky rail is received, the bolt cover is in conjunction with the curtain sheet that is positioned on the ladder rope, underbeam in stay cord and terraced hypomere combination of restricting, and the stator of button knot location, it is characterized in that:

It rail forms with three trifle noose windings, and sliding transfer mutually is to do suitable elongation and shortening;

The curtain sheet, stay cord hole of both sides is vertical slotted hole on it;

Underbeam adopts the winding of three trifle bolts cover to form, and can make sliding transfer, has elongation and shortens function, is provided with the perforation that supply stay cord be passed down through relative with stay cord on each joint;

Stator, has the complementary appearance that mutual chimeric card is tied with the hypomere of underbeam, its both sides are provided with the two through hole that passes for twice latter ends of ladder rope, central then be provided with one and be the poroid stay cord hole of plum blossom, and it is downward convex shape, after stay cord was passed from top to bottom, the reverse card that produced by the stay cord hole ended effect, can only pull out and the return that must not make progress downwards;

Aforementioned with the sun blind of regulating the length and width function, can pass through the contraction of day rail and underbeam, and the blade excessive portion is wiped out, reach horizontal wide adjusting; Also can be it is drop-down by the stay cord end, make stay cord be subjected to stator to give stationary positioned, and make underbeam rise, and unnecessary blade is removed, reach the adjusting of length.

Below in conjunction with an embodiment and conjunction with figs. the utility model is described in detail, wherein:

Fig. 1 is the lateral view of sun blind commonly used.

Fig. 2 is the part section constitutional diagram of sun blind commonly used.

Fig. 3 is the utility model three-dimensional exploded view.

Fig. 4 is the utility model front view.

Fig. 5 is the horizontal wide schematic diagram that dwindles of side-looking before the utility model.
