Abstract

The utility model relates to the technical field of daily living equipment, in particular to an improved structure for corrugated curtains and shutter curtains. The improved structure of curtain consists of an upper rail of curtain body, a lower rail of curtain body, and a pulling rope. Wherein, one end of the pulling rope which is wound out through the upper rail is vertically passed through the curtain body, and the end is led out through the lower rail and fixed on the lower rail. A winding device and a driving device are provided on the upper rail, a pulling rope lead-out end is provided in the driving device which comprises a first rotating wheel and a second rotating wheel, and the first rotating wheel and the second rotating wheel are connected by a fixed force spring. The driving device also comprises a third rotating wheel which is mutually engaged with the second rotating wheel. The fixed end of the pulling rope is led out from the lower rail, and the fixed end is a pulling rope fixing piece. The improved structure of curtain can obtain the effects of convenient use and easy operation, and can avoid the disadvantages that while in use, the opening and closing of traditional corrugated curtains and shutter curtains are mainly controlled by pulling ropes, and the ropes are easy to be wound.

Description

The structure-improved of curtain

Technical field:

The utility model relates to the daily living article technical field, refers in particular to a kind of structure-improved that is used on shutter curtain, the blind.

Background technology:

As everyone knows, curtain mainly is to provide the effect of sunshade with the protection privacy in modern room, divides the pull-type extendible up and down that reaches about existing curtain generally is divided into; Wherein, the extendible curtain mainly is up to fold or lowering downwards by the low end of stay cord with curtain up and down.As shown in Figure 1, in the prior art, the employed extendible blind up and down of people, the lower end of its affixed curtain body 70 in stay cord 71 lower ends, and stay cord 71 upper ends are drawn outside curtain body 70 by the stay cord brake component that is installed on the rail 72 after running through curtain body 70; The outer end that draws of time spent pulling stay cord 71 is mentioned curtain body 70 by stay cord 71 lower ends, and can be realized receiving on the curtain by stay cord brake component locking stay cord 71.Yet the revealed section elongation of the pulling of time receiving stay cord 71 end is situation sagging, that expose on the curtain, and swing not only influences the curtain aesthetic property with the wind, but also the incident that stay cord twines child and other article easily takes place.For example, the patent No. is that 97200121.2 Chinese patent has just announced that a kind of drawing cord for louver window hangs down with the safety button, it is to be formed by a female seat sheet and stroma sheet matched combined, after the combination, its bottom has the fulcrum of pivoted, make mother, fan-shaped can be opened in stroma sheet top, and the position is provided with a corresponding mutually flange in the central, constitute a narrow orifice, can be for its below, location, stay cord knotting back, top design becomes to have the structure of wearing mouth and intercalation piece, makes mother, the stroma sheet fastens the back and becomes the tight fit state, once child makes stay cord expand to both sides, then make mother, the strip off of stroma sheet, make stay cord and its disengaging, and slip-knot is opened, the accident generation that can prevent effectively that child's neck from being fasten or be strangled.

Summary of the invention:

The purpose of this utility model is to provide a kind of novelty simple in structure, Window curtain structure easy to use.

For achieving the above object, the technical solution of the utility model is: it includes rail on the curtain body, following rail and stay cord, its medium pulling rope one end is laid out by last rail and vertically through curtain body, and this end is drawn by following rail and is fixing, last rail is provided with Winder and drive unit, be provided with the stay cord exit in this drive unit, this drive unit also comprises first runner and second runner, is connected by fixed force spring between first runner and second runner.

Described drive unit also includes the 3rd runner, and the 3rd runner and second runner are the gear of two mutual engagements.

The fixed end that described stay cord is drawn by following rail is a stay cord fixture.

By above technical scheme, the utility model can reach easy to use, easy-operating effect, has avoided main upward receipts and shortcoming drop-down and that rope easily is wound by stay cord control curtain in traditional shutter curtain, the blind use.

The specific embodiment:

See shown in accompanying drawing 2～accompanying drawing 6, be the preferential preferred embodiment of the utility model use on shutter curtain, it includes curtain body 10, last rail 20, following rail 30, stay cord 40 and stay cord fixture 50, and in last rail 20, be provided with Winder 31 and drive unit 32, Winder 31 is the coiling runner of class liny wheel, this device can be made as one or more as the case may be, its effect is stay cord 40 share splits of will be drawn by drive unit 32 and introduces curtain body 10, be provided with first runner 321 in the drive unit 32, second runner 322 and the 3rd runner 323, connect by fixed force spring 33 (seeing accompanying drawing 4) between first runner 321 and second runner 322, and second runner 322 and the 3rd runner 323 are two pitch wheels.The fixing also part of one end of its medium pulling rope 40 is wound on the 3rd runner 323 (sees accompanying drawing 6), the other end is drawn by the 3rd runner 323, this end is by behind first Winder 31, be divided into two (can be divided into more multiply as required) respectively on two Winders 31, draw respectively by last rail 20 then and vertically through curtain body 10, and this end is drawn by rail 30 down and should be held by stay cord fixture 50 and to fix.

The utility model is to have increased drive unit 32 than the main improvement of prior art, when the user spurs down rail 30, because stay cord 40 is provided with stay cord fixture 50 (can certainly directly stay cord 40 be tied a knot) at following rail 30 places, therefore stay cord 40 is and then toward drop-down, stay cord 40 drives 323 rotations of the 3rd runner simultaneously, because the 3rd runner 323 and second runner 322 are the gear of two engagements, therefore the 3rd runner 323 can drive the rotation of second runner again, be fixed in second runner 322 on owing to fixed force spring 33 1 ends this moment, therefore fixed force spring 33 and then rotates and the generation convergent force, the convergent force that fixed force spring 33 is produced equals the gravity of curtain, thereby can make curtain rest on any position.Same principle, when receiving curtain on the needs, rail 30 under user's pop-up, and fixed force spring 33 produces convergent force, can make curtain rise to desired location.

In the present embodiment, the fixed force spring 33 that described being used to connects first runner 321 and second runner 322 is set to two, but its quantity can increase or reduce (accompanying drawing is not shown) as required.

See accompanying drawing 7～accompanying drawing 8, in addition, also the 3rd runner 323 can be set in the drive unit 32 of the present utility model, only connect first runner 322 and second runner 323, also can realize above-mentioned functions with fixed force spring 33.

See accompanying drawing 9, be the preferential preferred embodiment of the utility model use on blind, this preferred embodiment also is provided with a holder of being convenient to user's pop-up and drop-down curtain 60, and this device can be protected the clean and tidy, clean of curtain body 10.

The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
