Abstract
A casement automatic release mechanism for rolling blind is provided, which is characterized in that: the mechanism is composed of a casement rolling / releasing mechanism fixed on a rolling blind frame and a torsion spring connected between the frame and a casement winding drum and the two are connected with each other; a shaft is arranged in a spring ring of the torsion spring, which is connected with the frame and is provided with positioning blocks. The invention, compared with the prior art, has the advantages of releasing casement rolled on the casement winding drum automatically without needing to release part of the rolling blind first by manpower and capable of overcoming the high speed and impact force when releasing the casement as well as labor-saving when rolling the casement.
Description
Technical field:
The present invention relates to a kind of mechanism that reaches that discharges cord.
Background technology.
The automatic fallen curtain of existing casement, when needs are accepted casement, its casement be with folding mode be collected in curtain rod arm below, such collection mode is because therefore the weight of casement all concentrates on the stay cord,, need many stay cords to spur casement simultaneously, and the action of stay cord must be synchronous, so that casement folding and unfolding simultaneously successfully.This kind curtain is in case wherein stay cord disconnection will influence the normal folding and unfolding of casement, and exposed folding casement is also hidden dirt easily.In order to address the above problem, people adopt the mode of roller shutter to come automatically casement to be put down, but, because casement is to be wound on the casement reel of roller shutter, when beginning to put casement, because the casement that is wound on the casement reel does not have downward power, need artificial elder generation that roller shutter is put down a part, so that the casement that part of casement that puts down utilizes the gravity of himself will be wound on the casement reel pulls down.Though this kind curtain has solved the shortcoming of folding and retraction curtain, but, because when putting curtain, need artificial elder generation that roller shutter is put down a part, therefore, it is very inconvenient to operate, in addition, when the cloth amplitude ratio of casement bigger, when weight is heavier, the speed of its tenesmus and impulsive force are bigger, even adopt deceleration device, can not offset the speed and the impulsive force of its tenesmus well, and, along with the release of casement, the speed of casement tenesmus and impulsive force are also along with quick increasing, and the speed of excessive tenesmus and impulsive force can be destroyed the curtain relieving mechanism; During rolling,, need expend very big manpower, and along with the increasing of the casement that is discharged, needed manpower to strengthen also because casement is heavier.
Summary of the invention:
Goal of the invention of the present invention is to provide a kind of and need not wants artificial elder generation that roller shutter is put down a part, roller shutter just can be automatically casement on the casement reel puts down with being wound on, and no matter the curtain that is discharged is furnished with much, can both overcome the high-speed and impulsive force of casement tenesmus, labour-saving automatic release curtain cloth mechanism for roll screen during rolling.
The present invention realizes like this, by be fixed on the casement rolling/relieving mechanism on the roller shutter frame, the torque spring that is connected between frame and casement reel constitutes, casement rolling/relieving mechanism and casement reel link together, be provided with the axle that links together with frame in the turn of torque spring, axle is provided with locating piece.During work, size according to casement, determine the position of locating piece on axle, and locating piece is fixed on the axle, the position of locating piece on axle is to determine like this, when the cloth width of cloth that casement discharged is big, makes locating piece close toward the torque spring movable end, when the cloth width of cloth that casement discharged hour, make locating piece away from the torque spring movable end.Like this, do the action of rolling roller shutter cloth by the casement rolling/relieving mechanism drive casement reel that is fixed on the roller shutter frame, rotation along with the casement reel, the torque spring that links together with it is also along with rotation, when rolling roller shutter cloth finishes soon, torque spring is in the free state that does not have torsion, continue rolling roller shutter cloth until end, torque spring is also along with rotation, make torque spring from free state again to having a state of certain torsion, the direction of its torsion is opposite with previous direction, and like this, reel has been saved certain screen resilience under the effect of torque spring; When needing to be wound on roller shutter cloth on the casement reel and discharging, touch casement rolling/relieving mechanism, make the casement reel be in free rotary state, at this moment, under the effect of the screen resilience of torque spring, a part of roller shutter cloth is discharged from the casement reel, because part roller shutter cloth discharges from the casement reel and forms enough gravity, so in this section under the pulling of roller shutter cloth gravity, roller shutter cloth constantly discharges from the casement reel, torque spring also rotates along with the rotation of reel, at this moment, torque spring is returned to free state from having resilience torsion, arrive again and store the resilience torsion opposite with screen resilience, release along with casement, torque spring reverses, the diameter of turn is constantly dwindled, when the reduced of torque spring circle to less than the diameter of locating piece the time, torque spring circle lock ring on the locating piece is on locating piece, locating piece to torque spring between frame can not be reversed, have only locating piece to the torque spring between the torque spring free end just can reverse, like this, just increased the power that spring reverses, the power of reversing of the spring that is increased has been offset casement and has been continued to discharge the impulsive force that is increased, thereby has slowed down the speed of casement tenesmus effectively, has alleviated turning power required when casement turns round, under the gravity effect of roller shutter cloth, the casement that is wound on the casement reel puts down fully.In the time of need be with the casement rolling, touch casement rolling/relieving mechanism, make casement rolling/relieving mechanism and reel interlock, drive reel by casement rolling/relieving mechanism then and do the rolling rotation, at this moment, because torque spring has been saved certain torsion, and this torsion is to continue to increase along with the release of casement, like this, during rolling, under the effect of torsion, alleviated the power of rolling widely.
Casement rolling/relieving mechanism is made of rotating mechanism, clutch, and rotating mechanism links to each other with the casement reel by clutch.
Be connected with axle on the roller shutter frame, axle head is connected with deceleration device, and deceleration device and reel link together.During work, can slow down the speed and the impulsive force of roller shutter cloth tenesmus effectively by deceleration device.
The present invention compared with the prior art, owing to utilized screen resilience that spring saved initial driving force when discharging roller shutter cloth when the rolling of roller shutter cloth, simultaneously, the torsion that utilizes spring when roller shutter cloth discharges, to be saved, therefore, have and need not want artificial and earlier roller shutter is put down a part, roller shutter just can be automatically casement on the casement reel puts down with being wound on, and can overcome the high-speed and impulsive force that casement drops, labour-saving advantage during rolling.
