Feedback type curtain group retracting mechanism

A retracting mechanism of a feedback type curtain group, in particular, can reduce the deformation rate of the energy storage spring during energy storage or shorten the use length of the energy storage spring, and can be widely applied to a lightweight or heavy curtain group usage of.

The curtain group for self-recovery to achieve feedback retraction via an elastic energy storage element is basically composed of an elastic deformation element, the output end drives the reel, and the reel pulls the draw cord of the curtain, when the curtain is pulled by the external force, The pulling rope rotates the reel, and the rotating force of the rotating shaft is directed to the elastic element for energy storage. When the curtain is to be collected, the original stored energy of the elastic energy storage element is outputted to the reel, so that the self-winding recovery is achieved. Purpose, in the normal design of the unit, the elastic element directly drives the reel, often encounters insufficient output so that the curtain cannot be completely retracted. In this case, the working torque curve of the elastic element does not have the required strength, so it is adopted. The empirical value selects a coefficient of elasticity of the elastic element as a single gauge weight curtain.

In addition, if the length of the curtain is long, the number of the periphery of the shaft increases, and the elastic element is linked by the reel, so that the number of rotations is increased and the height is deformed, so that the curtain and the heavy weight can be dealt with longer and longer. The curtain quality, in order to overcome the amount of deformation of the elastic member, increases the volume of the elastic member such as the length.

Wherein, if the coefficient of the elastic element is high, the feedback force is large, and when the winding curtain is raised to the end, the lower mast of the curtain and the components of the curtain itself, such as the curtain, form an accumulated mass, plus recycling The stroke rate will produce an impact on the abdomen of the upper mast when the upper mast is received. If the impact force is reduced, the elastic element with lower elastic modulus is used, but the feedback energy is used. Insufficient, there will be a possibility that the lower mast cannot be completely closed.

The pulling force of the pull-down cord 10 is very light, such as the energy storage spring 300 of the elastic feedback device 3 can be amplified at an energy speed of 4:1, and the energy storage spring 300 is pulled when the cord 10 is pulled down by any height. The energy of the reverse output is driven by the external force, which keeps the height of the pull cord 10 lowered, and the lower mast 12 as shown in Fig. 1 is fixed at any height of the winding stroke. If the spring constant of the energy storage spring 300 is large, the adjustment of the worm 42 provided by the torque adjustment device 4 can be obtained by changing the angular position of the worm wheel 41 by the adjustment rod 421 of the worm 42. When the adjustment lever 421 is tightened, the energy storage spring 300 is pressed against the load spring, and when the adjustment lever 421 is released to change the radial direction of the worm wheel 41, the elastic energy storage of the energy storage spring 300 is reduced.

The output can be used to adjust the quality of the curtain assembly 1 unequally, and the space inside the elastic feedback device 3 is slowed down by the shifting device 5, the energy storage spring 300 can be shortened to slow down the occupancy of the elastic feedback device 3 The internal space, when the pull cord 10 is pulled down, its force is very light, which can store 4 times of the energy stored in the energy storage spring 300, and when the energy storage spring 300 is to be wound back to the drawstring 10, it will be 4:1. The output energy pulls the drawstring 10, so the drawstring 10 can be easily positioned at any height position, and the working curve of the energy storage spring 300 can also be adjusted through the torque adjustment device 4, and the working curve can be selected. The smooth line segment is taken, and the only design that is completely innovated in the feedback curtain group collection is requested to be clearly reviewed by the examiner.
