Problems solved by technology

[0003] When the roller blind in the prior art is rolled up around the rolling rod, the roller blind is instantly rolled up by the elastic force of the winding spring, and the instant rolling up will cause people to be frightened and generate noise
[0004] That is, since the roller blind is rolled up around the roller rod by the elastic force of the coil spring under torsional pressure, and the roller blind is rolled faster and faster with the increased winding speed, the handle bar will collide with the accommodating roller. rod housing, thereby generating noise

Abstract

The invention relates to a reduction gear for a roller shutter, wherein, the compressed piston of the reduction part can enter into a cylinder connected with one inner end of the roller pole. The invention also relates to a device which folds and unfolds the roller shutter simply and conveniently, in particular to a device which can fold the roller shutter by decreasing the folding speed at a certain section when folding the roller shutter, thereby has the advantages of avoiding noises, collisions and accidents, and easy operation without any limit by age or gender (the young people, the old people or male and female).

Description

technical field [0001] The present invention relates to a deceleration device for a roller blind, especially a device capable of rolling up and unrolling a roller blind easily and conveniently, and more particularly, to a device which can Roll up the roller blind by reducing the speed of the roller blind in a certain section, so the device can prevent noise, collision, and safety accidents, and can be independent of age or gender (young, old or male, female) And can be easily operated. Background technique [0002] Typically, roller blinds are used as a replacement for curtains, which operate by being rolled up or unrolled around a roller rod, and when the user pulls the handle bar, the roller blind is rolled up by overcoming the spring force of the coil spring up or unfold. Through computational photography, roller blinds can be used as a decorative item displaying various photos, pictures, etc., and it can also be used as a substitute for framed home pictures on walls or...
