Abstract
The present invention discloses a kind of curtain unidirectional control device with clamping function and curtain thereof, when described power transmission shaft active rotation, its first projection props up a contact part of described rotation spring, have an effect from inside to outside, the turn-knob portion making described rotation spring reduces in circumferential direction, rotation spring rotates, and then drives described first tumbler to rotate, thus drives described second tumbler to rotate；When described first tumbler active rotation, the spacing breach of described first tumbler props up a contact part of described rotation spring, and ecto-entad is had an effect so that the turn-knob portion of described rotation spring amplifies in circumferential direction, and rotation spring cannot rotate.Compared with prior art, the curtain unidirectional control device with clamping function of present invention offer and curtain thereof, controller can provide good non-return effect, and controlling curtain will not decline because of the action of gravity of self so that the accurate positioning that curtain rises or falls.
Description
Technical field
The present invention relates to curtain field, be exactly a kind of unidirectional control of curtain with clamping function
Device processed and curtain thereof.
Background technology
Curtain is to use one the most widely in the curtain world, is generally used for office space the most, in Europe
In man of the U.S., curtain also has and much uses in household building, and it is well received with brevity and lucidity.Window
Curtain can be divided into horizontal curtain and vertical curtain by mounting means, can be divided into manual and electronic two kinds by control.
In first generation horizontal curtain, when curtain is launched by Non-follow control and the action such as packs up, it is common that by setting
Curtain is controlled by the meter rope in end or line.Due to the rope of curtain or line generally bottom is controlled one
End suspension, and the position of suspension is the most equal with the bottom of curtain so that human or animal can connect the most easily
Contact rope or the line of curtain, and then there is human or animal and may be restricted or line enwinds and can not shake off, even
Human or animal is caused to be tied tight and the probability of life danger occurs.
In second filial generation horizontal curtain, curtain changes and is operated by rod-type, by the exhibition of rotation process bar curtain
The action such as open and pack up, then by ropewinder rolling and stop curtain to decline, thus avoid rope or the danger of line.
But owing to curtain self exists certain weight, when the dynamics that ropewinder is non-return is inadequate, curtain can be because of certainly
The action of gravity of body and decline, or the location of the rise and fall of curtain is not accurate enough, is further improved.
Summary of the invention
For drawbacks described above, present invention solves the technical problem that and be to provide a kind of curtain with clamping function
