Description

Concealed curtain

The utility model belongs to the special installation relevant with door and window, particularly the Scroll curtain.

Present curtain all is along track left and right sides open-type, and no matter always be exposed to the outside day and night to casement, dirty easily, unbecoming again.

The purpose of this utility model is design one and Scroll curtain.When needing, casement can be pulled out, not the time spent, casement twists on the outer tube, and is both clean, clean and tidy again.

Below, narrate structure of the present utility model with reference to accompanying drawing.

An axle 3 is installed at two ends at curtain rod arm 1, and an end of axle 3 links to each other with outer tube 2 by axle sleeve 4, and the other end links to each other with outer tube 2 by ratchet 6.The recess 10 that can hold roller 8 is arranged in the ratchet 6, the recess 9 that is attached thereto is arranged in a side of recessed window 10.On the axle 3 relative recess 11 is arranged also, at gland 7, be used for roller 8 is enclosed in the ratchet 6 in the side of ratchet 6 with recess 10.Other has a spring 5, and the one end is fixed on the axle 3, and the other end is fixed on the ratchet 6.Outer surface at outer tube 2 is installed casement.

Recess 11 and the recess on the ratchet 69,10 on the above-mentioned axle 3 can be provided with several.Roller 8 also can change ball into.

For the ease of handling this mechanism, the outer surface of ratchet 6 can be made groove 13, wherein twine cotton rope.

Narrate operation principle of the present utility model below with reference to Fig. 3.

When pulling down cotton rope or casement, when ratchet 6 is counterclockwise rotated, the convex shoulder 12 on the ratchet 6 will fall into the recess 11 interior rollers 8 of axle 3 and release, and be in the recess 10 of ratchet 6, rotate with ratchet 6.So ratchet 6 drives outer tube 2 and rotates, and curtain is pulled out.Want to make curtain to be parked in a certain position,, clockwise rotate under the effect of the spring 5 of ratchet 6 as long as slowly loose one's grip, at this moment roller 8 falls between recess 9 and 11, because the distance between the recess 9 and 11 is less than roller 8 diameters, so roller 8 has blocked ratchet 6, promptly curtain stops lifting.Want curtain is rolled, as long as pull down cotton rope or curtain with hand, unclamp cotton rope then suddenly, under the effect of spring 5, cause the roller 8 (pull down cotton rope, when ratchet 6 changeed counterclockwise, roller 8 was in the recess 10 always) that is in the recess 10 to have little time to roll out, along with ratchet 6 promptly clockwise rotates, roll so drive curtain.

This concealed curtain can be involved in the pelmet by day, not only neatly but also health.And this curtain can rest on any position, is convenient to keep the sun off.This curtain pulls decline, rises (volume) automatically and rises.

Adopt this curtain machinery also can make lift wall or curtain.

The drawing explanation:

Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the partial enlarged drawing of A portion, does not wherein draw roller 8, and Fig. 3 is the B-B profile.

Embodiment:

At axle 3 of the two ends of curtain rod arm 1 peace, an end of axle 3 is by axle sleeve 4, and the other end links to each other with outer tube 2 by ratchet 6.Outer tube 2 can freely rotate on axle 3.One side of ratchet 6 plays the axle sleeve effect, and opposite side has three groups of recesses 9 that are mutually recess 10 hexagonal angle, that can hold roller 8 and are attached thereto.On the axle 3 two recesses 11 that are in the diameter two ends are arranged.On the ratchet 6 on recess 9 and the axle 3 degree of depth of recess 11 can be stuck in standard wherein to guarantee roller 8.There is gland 7 in the outside of ratchet 6.Outer surface at outer tube 2 posts the sticking lock of nylon, also is sewed with the sticking lock of nylon on the casement.Can install easily like this or the demolition casement.

This curtain lifting freely, clean and tidy, attractive in appearance.
