Motor-transmission device double-rail electric curtain machine capable of opening and closing two curtains in single direction or double directions

Abstract

The invention relates to an electric curtain machine. The electric curtain machine comprises a motor, a transmission device and a double-rail aluminum alloy machine box with the -shaped cross section and is controlled manually with one button, capable of performing limiting automatically, provided with a built-in minitype clutch device and capable of driving one curtain (a window shade or a gauze shade) or simultaneously driving two curtains (window shades or gauze shades). The electric curtain machine overcomes the defects existing in the situation that a motor and a transmission device cannot simultaneously drive double rails and two curtains. A minitype alternating current gear motor, a clutch driving device with a major functional piece arranged in a hollow wheel hub of a driving wheel, a driven wheel device with the tension capable of being adjusted, a nickel-plated chain, nylon travel idler wheels, nylon idler wheels, nylon pulleys, a travel limiting switch and stainless hooks are integrated inside and outside the double-rail aluminum alloy machine box. According to the electric curtain machine capable of being operated by hand after power failure, the chain is made to make horizontal reciprocating motor in the machine box through frontward and backward rotation of the motor so that the one or two curtains below the double rails can be driven to be opened or closed and stopped in a single direction or in double directions and can make the two curtains be opened or closed simultaneously.

Description

Technical field [0001] The invention relates to a miniature AC deceleration motor, a set of transmission device, one-button manual control, automatic limit, has double tracks, can drive up to two sets of curtains at the same time, and the active end is equipped with a miniature pull-wire clutch, which can be used during power failure. Manual electric curtain machine; it is based on a miniature AC geared motor, a stainless steel motor base, a nickel-plated chain with a long pin shaft, and a set of main functional parts controlled by two pull wires inside the hollow wheel drum of the driving wheel. Steel balls to realize the active device of the clutch action, a set of built-in compression springs to adjust the tension of the passive wheel device, a tower spring, a compression spring, a travel limit switch, two nylon travel rollers, nylon rollers, Nylon fixed pulleys, nylon free pulleys, and stainless steel hooks are integrated in the cross section Inside and outside the doubl...

Problems solved by technology

[0003] The invention of "one motor, one transmission device, two tracks, two sets of curtains, single and two-way opening and closing electric curtain machine" overcomes the shortcomings that one motor and one transmission device cannot simultaneously drive two tracks and two sets of curtains (blackout curtains, gauze curtains); Through the positive and negative rotation of a miniature AC geared motor (hereinafter referred to as "motor"), it drives the only transmission device with a miniature cable clutch, so that the cross section is Shaped double-track aluminum alloy box (hereinafter referred to as "aluminum alloy box"), one set of one, one set of two, two sets of two, and at most two sets of four curtains under the double track for one-way or two-way (Choose one of the two) opening and closing (hereinafter referred to as "opening and closing"), which can realize the opening of one set of curtains (such as: blackout curtain) and the closing of another set of curtains (such as: gauze curtain) at the same time
