The specific embodiment

At first, please by Fig. 1 to sight shown in Figure 4 it, it includes: a pedestal 10, one rotating seat 20, two wind springs 30, one brake component 40 and folding and unfolding wheel 50, wherein, pedestal 10 has a base plate 11, with the high side plate 12 up from base plate 11 both sides, 12 of biside plates are pivoted with one first axostylus axostyle 13 in regular turn, one second axostylus axostyle 14, one the 3rd axostylus axostyle 15 and one the 4th axostylus axostyle 16, the

3rd axostylus axostyle

15 and 16 of the 4th axostylus axostyles are to carry out transmission with the binding of gear train 17, on second axostylus axostyle 14, then be arranged with a transmission rope 18, rotating seat 20 is to be set on second axostylus axostyle 14, make wind spring 30 can be located at rotating seat 20 both sides, to be set in respectively on first axostylus axostyle 13 and the 3rd axostylus axostyle 15, wind spring 30 outer ends and combination fix on the volume clad can 21 of rotating seat 20, make two wind springs 30 can be controlled by rotating seat 20 with its reed compression coil on the volume clad can 21 of rotating seat 20, or elasticity turn-off, brake component 40 has one first end 41 and one second end 42, this first end 41 is to enlarge toward second end, 42 asymptotic expressions, make brake component 40 can constitute a coniform appearance, be provided with a helicla flute 43 that is connected in 42 at first end 41 and second end in brake component 40 peripheries along its tapering, and this brake component 40 is to be set on the 3rd axostylus axostyle 15 with first end 41 and wind spring 30 adjacent forms, transmission rope 18 can be stretched out from second axostylus axostyle 14, and be combined near on the periphery of second end 42, folding and unfolding wheel 50 is arranged on the 4th axostylus axostyle 16, to provide a stay cord 51 to be wound in wherein, this stay cord 51 and down doing hangs, so that in order in conjunction with the curtain sheet.

During its actual use, push away on being or drop-down curtain sheet, open and close with the control curtain, drive 16 rotations of the 4th axostylus axostyle by stay cord 51 through folding and unfolding wheel 50, the engagement of mate gear group 17, be to furl or to decontrol to utilize 40 pairs of transmission ropes 18 of brake component on transmission of power to the three axostylus axostyles 15, allow second axostylus axostyle 14 also can produce synchronous running, at this moment, the wind spring 30 that volume overlays on the rotating seat 20 will be flicked outward, in order to furl the curtain sheet upwards, or can be when the curtain sheet is drop-down, overlay on the rotating seat 20 with the reed volume, in order to accumulate the power that elasticity is taken back, by this design, can reach the effect that the ease of Use curtain opens and closes.

Continuous please by Fig. 5 and sight shown in Figure 6 it, it utilizes helicla flute 43 to guide transmission rope 18 gradually toward reeling than first end 41 of path from second end 42 in big footpath, can reach the stopping effect under the normality, to avoid the curtain sheet after adjustment, down to hang naturally again, or the curtain sheet down launches rapidly or up folds, and cause injury to personnel, namely, because second end 42 of brake component 40 is to enlarge with respect to second axostylus axostyle 14, so when second end 42 rotates a circle, second axostylus axostyle, 14 gesture must be rotated two circles, or even multi-turn, could produce with brake component 40 and cooperate, but because second axostylus axostyle 14 will rotate, must overcome the elastic force of wind spring 30, and reed volume overlayed on the rotating seat 20, could reach smoothly, and be controlled by second end 42 when second axostylus axostyle 14, when carrying out the rotation rapidly of two circles or multi-turn, this required elastic force that overcomes must be two times under the normal condition, or even many times, and depend merely on weight and the gravity traction of curtain sheet, be to be not enough to produce these two times, or even many times strength, with 14 rotations of smooth stopper second axostylus axostyle, so the curtain sheet can't hang naturally, in order to reach certain location in the use.

In sum, the utility model has reached breakthrough structure design really, and has the author content of improvement, can reach simultaneously usability and progressive on the industry again, and the utility model does not see any publication, also have a novelty, when the regulation that meets the relevant law of Patent Law, so propose novel patent application in accordance with the law.

Only above-described, only be a preferred embodiment of the present utility model, when can not with the scope implemented of restriction the utility model; Be that every equalization of doing according to the utility model claim changes and modifies, all should still belong in the scope that claim of the present utility model contains.
