Abstract
The invention provides a scroll force-changing spring which can be used for a rolling structure of a blind. When the blind needs to be rolled, assistance can be provided so that the blind can be rolled conveniently. The scroll force-changing spring comprises a center round bar and a long-bar-shaped spring leaf. The tail end of the spring leaf is connected with the peripheral face of the outer ring of the center round bar in a welded manner. The spring leaf is wound around the peripheral face of the outer ring of the center round bar in a rolled manner. The initial end of the spring leaf is provided with a non-elastic-force connecting end. The elastic force of the spring leaf is gradually reduced step by step from the initial end to the tail end. The initial end of the spring leaf is of a transition structure which is closed up from the two sides to the center. An installation structure is arranged at the front end of the transition structure, and a connecting end is formed by combining the installation structure and the transition structure.

Detailed description of the invention
A kind of scrollwork becomes strength spring, see Fig. 1～Fig. 3: it includes the reed 2 of center pole 1, strip, the end 3 of reed is welded to connect the outer circumferential surface of center pole 1, reed 2 coiling is in the outer circumferential surface of center pole 1, the initiating terminal of reed 2 is provided with inelastic link, the elastic force of reed caudad successively decreases step by step from initiating terminal, the initiating terminal of reed 2 is the transition structure 4 closed up from two lateral centers, the front end of transition structure 4 is connected to mounting structure 5, mounting structure 5 and transition structure 4 combination and forms link.
Mounting structure 5 is specially by the middle part card structure to both sides evagination, and it is for withholding the body of correspondence；
The length of the reed 2 of strip is in the height under fully open state equal to sun blind, and mounting structure 5 is installed in the rotatable parts of the stay cord for driving shutter.
Specific embodiment one, seeing that Fig. 3, the overall length of reed 2 are 1400mm, the initiating terminal of reed 2 leaves the inelastic part of 35mm, includes mounting structure 5 and transition structure 4, elastic force and the length of the elastic part of reed 2 are shown in Fig. 3, and it makes the bottom of sun blind can be completed rolling by light holder.
nullA kind of scrollwork becomes the method that strength spring is applied to sun blind，Specific embodiment one、See Fig. 4: it includes the gear structure of four single layouts that are in line，Sequence number is respectively 1.、②、③、④，Adjacent gear structure intermeshes connection，Two scrollworks become strength spring and are set with in the gear structure of even number sequence number，The card structure of two scrollwork change strength springs 6 is installed in the corresponding card holding trough 8 of the gear structure of the odd indexed of less than the gear structure at its place 1 respectively，The outer ring surface of the card holding trough 8 of the gear structure of odd indexed is cylinder anchor ring 9，Rolling for corresponding strip reed，1. sequence number is、Around equipped with stay cord 7 in the lower end rotating shaft 10 of gear structure 4.，The end of stay cord 7 is installed in the blade of bottommost after extending through the blade of every sun blind，This structure is applicable to the structure that sun blind are heavier，Two groups of scrollworks become strength spring and complete the rolling of sun blind.
Specific embodiment two, see Fig. 5: sequence number is that the upper end cylinder anchor ring combination of gear structure 2., 3. forms scrollwork and becomes the rolling assembly of strength spring 6, sequence number is that the upper end cylinder anchor ring of gear structure 1., 4. is rotating around equipped with stay cord 7, the end of stay cord 7 is installed in the blade of bottommost after extending through the blade of every sun blind, this structure is applicable to the structure that sun blind do not weigh, and one group of scrollwork becomes strength spring and can complete the rolling of sun blind.
Scrollwork become strength spring 6 can be additionally used in T rope driving, T rope is arrange in short transverse corresponding to blade, the blade of bottommost is upwards slightly held up with hands, instantaneous time scrollwork becomes the resistance rotated that the pull-back forces of strength spring 6 generation is subject to more than gravity and the stay cord of blade, stay cord 7 is by a part of pulling back, and then drive T rope (not shown in FIG., belong to existing mature structure) upper end by a part of returning so that each blade is all to the angled vane group becoming part shading or light transmission state of returning.
Because the gravity that curtain is suffered by the process of initial rise is maximum, need the elastic force that reed offer is relatively large, and when curtain is after by part rolling, the elastic force demand of reed is gradually reduced, therefore the elastic force of reed caudad successively decreases step by step from initiating terminal, this scrollwork becomes strength spring and may be used for the rolling structure of sun blind, can provide power-assisted when needs sun blind carry out rolling so that the rolling of sun blind is convenient.
Above specific embodiments of the invention are described in detail, but content has been only the preferred embodiment of the invention, it is impossible to be considered the practical range for limiting the invention.All equalizations made according to the invention application range change and improvement etc., all should still belong within the patent covering scope of the present invention.
