The invention relates to a bidirectional coaxial spiral clutch device in wire-wound type door window pulling transmission. By the adoption of a flexible transmission principle of single and double-roller wire winding of all types of the conventional door window shutters, the freedom that a user opens and closes a door window with a hand every day is limited due to the fixed connection between a transmission wire and the door window, and the problem that the winding and unwinding speeds of the two ends of the conventional transmission wire are different exists. The bidirectional coaxial spiral clutch device provided by the invention consists of a winding wire, a shaft sleeve with external threads, a rotary power shaft, a connection piece, a fixed pulley and two rollers with internal threads. When the shaft sleeve with the external threads is screwed into any one of the two rollers with the internal threads, the shaft sleeve and the corresponding roller are driven to rotate together through the lamination of stopping surfaces on the shaft sleeve and the roller; at the moment, the shaft sleeve is completely separated from the other roller; therefore by separating from one roller and combining with the other roller, the bidirectional coaxial spiral clutch device is formed; the problems that the manual opening and closing freedom of the user is limited and the winding and unwinding speeds of the two ends of the transmission wire are different can be effectively solved.
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 ...
