Roller blind balance regulator and roller blind with same

Abstract

The invention discloses a roller blind balance regulator and a roller blind with the same. The roller blind balance regulator comprises a stepped shaft and a friction drum; the stepped shaft is provided with an external screw thread; the stepped shaft penetrates through the friction drum; the friction drum is provided with an internal screw thread; the friction drum is in threaded connection withthe stepped shaft; and a friction layer is arranged between the friction drum and the stepped shaft. The roller blind comprises a roller blind rod, fabric, two mounting members and the roller blind balance regulator, wherein a return spring is arranged in the roller blind rod. The roller blind rod drives the friction drum to rotate, the friction drum moves in the axial direction of a limiting threaded rod while the friction drum rotates, and thus the friction force between the friction drum and a friction layer is increased or decreased. When the roller blind rod rotates, the friction force between the friction drum and the friction layer can be increased or decreased along with change of torque of the return spring, and thus the function of dynamically balancing the return spring is achieved. By means of the roller blind balance regulator and the roller blind with the same, the torque of the return spring can be balanced better, the friction force between the friction drum and the friction layer can dynamically compensate the torque difference of the return spring, and the using effect is good.

Description

technical field [0001] The invention relates to a roller blind balance adjuster in the technical field of household articles and a roller blind composed of the same. Background technique [0002] Roller roller blinds are more and more used by people, but children often bring some safety hazards because of the beads. In some places, bead roller blinds are difficult to install and inconvenient to operate, but they cannot increase the cost of installing electric roller blinds, and in some places there is no power supply. In order to solve these problems, the demand for push roller shutter systems is increasing. The hand-push roller blind system is realized under the condition of spring preload. During use, as the curtain body rises or falls, the elastic force of the spring on the roller blind rod is different. In long-term use, each zero When the transmission force of accessories changes, the torque will be difficult to balance, which seriously affects the use of roller blind...

AI Technical Summary

Problems solved by technology

The hand-push roller blind system is realized under the condition of spring preload. During use, as the curtain body rises or falls, the elastic force of the spring on the roller blind rod is different. In long-term use, each zero When the transmission force of accessories changes, the torque will be difficult to balance, which seriously affects the use of roller blinds

Therefore, the current roller blind system on the market must be customized according to different widths, heights, and even different fabrics. This will result in a large number of specifications, increased inventory, and inconvenient production.
