Abstract
The invention relates to the technical field of articles for daily use, in particular to a method for winding a curtain torsional spring, which comprises the following steps of: winding a strip into a cycling and laminating circle; thermally treating the strip wound into the circle and then forming to obtain a coiled spring with a big-to-small change of the curvature radius from the inner diameter to the outer diameter; and uncoiling the thermally treated and formed coil spring into the strip, and winding from one end with small curvature radius to one end with big curvature radius to form the torsional spring with reversed force. The invention has the advantages that the torsional spring ensures that a user feels more and more easy when unfolding the curtain and more and more laborsaving when folding the curtain, has a simple structure, is convenient for use, and meets the demands of the user.
Description
Technical field
The present invention relates to the daily living article technical field, be meant a kind of curtain torque spring winding method especially.
Background technology
Curtain has been widely used in places such as family, school, hotel, office building at present as a kind of daily living article, and the curtain of folding is easy to use because of it especially up and down, good looking appearance, and be subjected to people's favor more.
Known torque spring is also referred to as S type spring, be that the band coiling is become a circulation, stacked circle during moulding, the band that coiling is become circle is finalized the design after Overheating Treatment again, promptly obtains be changed to from large to small the torque spring of a radius of curvature to interior radial outer diameter.But, there is certain defective in actual use in the torque spring that coiling in this way forms, with sun blind is example: when by the pulling stay cord or directly draw or during the lower end expansion curtain of pop-up curtain with subordinate, torque spring has born all blade gravity by original state, it is fewer and feweri to become its blade gravity that bears, should feel to draw lighter and lighter during use and just meet user's demand, and the torque spring of this moment is increasing because of the radius of curvature of effect, caused elastic force also increasing, draw when having caused the user to launch curtain and more require great effort, and may appear under the situation of no any external force effect, increasing screen resilience is with the phenomenon of a curtain automatic drawing back part; During gathering, torque spring is by only bearing curtain least significant end blade gravity, fade to the gravity that it bears all blades, spring should help the user to reduce the demand that the power of lifting just meets the user, and the torque spring of this moment is increasing because of the radius of curvature of effect, caused elastic force more and more littler, more and more required great effort when causing the user to draw curtain in.
Summary of the invention
The present invention is in order to overcome the deficiencies in the prior art, and provides a kind of simple in structure, uses laborsaving convenience, the reversible curtain torque spring of strength winding method.
The present invention is achieved through the following technical solutions, and winding method may further comprise the steps:
1. the band coiling is become a circulation, stacked circle;
2. the band that again coiling is become circle is finalized the design after Overheating Treatment, promptly obtains be changed to from large to small the wind spring of a radius of curvature to interior radial outer diameter;
3. at last the wind spring after the heat treatment typing is launched, to the big end coiling of radius of curvature, form the torque spring that strength reverses by the little end of radius of curvature.
The invention has the advantages that this torque spring makes the user draw lighter and lighter, receives more laborsaving and more laborsaving when drawing curtain in when launching curtain; And simple in structure, easy to use, satisfied user's demand.
Description of drawings:
Fig. 1 is a user mode schematic diagram of the present invention;
Fig. 2 is a structural representation of the present invention.
The specific embodiment:
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described further, shown in Fig. 1 to 2, the present invention includes following steps:
1. the band coiling is become a circulation, stacked circle;
2. the band that again coiling is become circle is finalized the design after Overheating Treatment, promptly obtains be changed to from large to small the wind spring of a radius of curvature to interior radial outer diameter;
3. at last the wind spring after the heat treatment typing is launched, to the big end coiling of radius of curvature, form the torque spring 11 that strength reverses by the little end of radius of curvature.
The user imposes on the downward active force of curtain during expansion, add the gravity of curtain self, at this moment the curtain lower end is subjected to make a concerted effort the downwards pulling force that makes progress greater than stay cord 3, thereby overcome the opposition of torque spring 11, reel 2 rotates towards the direction of unwrapping wire, and stay cord 3 is realized the following exhibition that curtain is mated in elongation.Wherein, also follow rotation with the rolling wheel 12 of reel 2 gear part 21 engagement, a part of torque spring 11 that also just increased rolling on the rolling wheel 12, torque spring 11 volumes of rolling on the auxiliary rolling wheel 13 are several then to be reduced.Because the end coiling that torque spring 11 radius of curvature are big is fixed on the rolling wheel 12, the end coiling that radius of curvature is little is fixed on the auxiliary rolling wheel 13, when curtain constantly launches, the radius of curvature that acts on the torque spring 11 on the stay cord 3 is also more and more littler, and promptly elastic force diminishes gradually, and the gravity that correspondingly acts on curtain on the stay cord 3 constantly reduces, therefore the user can easily overcome the expansion that elastic force is realized curtain, and draw more laborsaving and more laborsaving, launch fully, reach the purpose of Automatic Positioning Control until curtain.
The user upwards holds up the lower end of curtain with hand during gathering, adds the elastic force of torque spring 5 original maintenance balanced actions, and what make progress makes a concerted effort greater than the curtain deadweight, and rolling wheel 12 discharges torque springs 11, auxiliary 13 rolling torque springs 11 of rolling wheel.When curtain constantly draws in, the radius of curvature that acts on the torque spring 11 on the stay cord 3 is also increasing, be that elastic force increases gradually, the curtain gravity that correspondingly acts on the stay cord 3 constantly increases, therefore the user can easily realize the gathering of curtain by elastic force, and receipts are laborsaving more more, when torque spring 11 complete rollings are extremely assisted on the rolling wheel 13, promptly realized folding fully of curtain.
Claims (1)
1. curtain torque spring, winding method may further comprise the steps, and the band coiling is become a circulation, stacked circle;
The band that coiling is become circle is finalized the design after Overheating Treatment again, promptly obtains be changed to from large to small the wind spring of a radius of curvature to interior radial outer diameter;
It is characterized in that: the wind spring after the heat treatment typing is launched, to the big end coiling of radius of curvature, form the torque spring that strength reverses by the little end of radius of curvature.
