Problems solved by technology

A clutch is provided in the top rail of the existing venetian blinds, so that the venetian blinds can realize a semi-automatic lowering function, all of which are moved downward by the weight of the venetian blinds themselves. stop, and then the venetian blind must be lowered to the bottom by the pull rope, which affects the user's use and lost time cost; Pulling force will make the top cabinet unstable after a long time, which is likely to cause safety hazards

Abstract

The invention provides a venetian blind. The venetian blind comprises a pull rope top rail, a transmission mechanism, a brake head and a shutter blind. The transmission mechanism comprises a driving rod and a winder and a clutch which are sheathed on the driving rod. The top rail is internally provided with an assistive mechanism. The assistive mechanism comprises a box, a gear group, a top coverand a coil spring installed in the box. The box is internally provided with a first fixing column and a second fixing column. The first fixing column and the second fixing column can be rotated relative to the box. The first fixing column is winded by one end of the coil spring, and the end part of the other end is fixed on the second fixing column. The top of the box is provided with a groove. The gear group comprises a first gear installed in the groove and fixed on the second fixing column and a second gear installed at a groove opening and matched with the first gear. The second gear is provided with a first shaft sleeve. A position, opposite to the first shaft sleeve, on the groove is provided with a second shaft sleeve. The first shaft sleeve and the second shaft sleeve are sheathedon the driving rod.

Description

technical field [0001] In particular, the invention relates to a venetian blind. Background technique [0002] Venetian blinds are used to shade window and door openings to block light and maintain privacy. With the development of the national economy, people's requirements for quality of life are increasing day by day, and window decoration products are also developing rapidly. As a product with rich functions of page turning and dimming, blinds have more and more application requirements. [0003] A traditional venetian blind includes a top rail, a venetian blind, a lower beam, a transmission mechanism for adjusting the rise or fall of the venetian blind, an adjustment mechanism for adjusting the opening and closing angle of the blades, and the transmission mechanism includes a driving rod and a wire reel. A clutch is provided in the top rail of the existing venetian blinds, so that the venetian blinds can realize a semi-automatic lowering function, all of which are moved...
