Abstract

The invention relates to a bidirectional coaxial spiral clutch device in a wire-winding type door and window pulling transmission. When the existing types of door and window openers adopt the flexible transmission principle of single and double roller winding, the fixed connection between the transmission line and the door and window limits the freedom of the user to manually open and close the door and window in daily life, and there are still gaps at both ends of the existing transmission line. The problem of different speeds of take-up and take-up lines. The invention proposes a two-way coaxial screw clutch device consisting of winding wires, a shaft sleeve with external threads, a rotating power shaft, a connecting piece, a fixed pulley and two rollers with internal threads. When the shaft sleeve with external thread is screwed into any one of the two rollers with internal thread, it is driven to rotate together by the fit of the stop surfaces set on both sides. At this time, the sleeve completely leaves the other roller, and a The clutch and the clutch form a two-way coaxial spiral clutch device, which can effectively solve the problems of the user's manual switch freedom limitation and the speed difference between the two ends of the transmission line.

Description

technical field [0001] The patent of the invention relates to a bidirectional coaxial spiral clutch device in a wire-wound door and window pull transmission, which belongs to the technical field of mechanical transmission. Background technique [0002] At present, all kinds of door and window shutters on the market are mainly of rigid transmission structure, using rack drive, chain drive, screw drive or connecting rod drive, and a few of them use the flexible transmission principle of synchronous belt or winding, among which, winding When using the flexible transmission principle, the fixed connection between the transmission line and the doors and windows limits the freedom of the user to manually switch the doors and windows in daily life, and may cause damage to the winding transmission system due to people's habitual manual switching behavior. In order to solve this problem, the present invention proposes a two-way coaxial screw clutch device without manual intervention ...
