Electrical and hand-cranking dual-purpose chain window opener capable of opening window in emergency

Abstract

The invention discloses an electrical and hand-cranking dual-purpose chain window opener capable of opening a window in an emergency. The window opener comprises a shell, an installation support, a motor assembly, a chain assembly and a connecting piece and further comprises a hand-cranking device. The shell is arranged on a window frame through the installation support. The motor assembly is connected with the chain assembly. The motor assembly and the chain assembly are arranged in the shell. The connecting piece is connected with the chain assembly and arranged on the window. The hand-cranking device is arranged on the motor assembly and the shell. The motor assembly comprises a speed reducing mechanism shell, a motor, a motor mounting base, a speed reducing mechanism and a control panel. A clutch device is arranged between the motor and the speed reducing mechanism. The clutch device controls the motor to be separated from the speed reducing mechanism. The problem that when a window opener encounters power failure or a controller breaks down, and the window opener cannot work, a chain cannot be moved, and accordingly the window cannot be opened or closed is solved. When various emergencies happen, for example, the window cannot be opened or closed, the window can be better opened or closed in the emergency.

Description

technical field [0001] The invention relates to the technical field of electromechanical window openers for building high-tech materials, in particular to an electric hand-operated dual-purpose chain window opener capable of opening windows in an emergency. Background technique [0002] With the development of society, window openers are widely used as an important part of ventilation and home automation. At present, there are many kinds of window openers, and the chain type window openers are most widely used due to their simplicity and beauty. However, in the actual use of the existing window drive, if there is a power failure or a controller failure, the window drive will not work, and the chain will not move and the window will not be able to be opened or closed, which will cause inconvenience to the user and cause trouble. In an emergency, encountering the above situations will cause great losses to users, even personal safety injuries. Due to the compact structure of...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the above-mentioned problems that the window opener cannot work in the event of a power failure or controller failure, and the window cannot be opened or closed due to the immobility of the chain, the present invention provides an electric hand-operated dual-purpose chain window that can open the window in an emergency In the face of various unexpected situations such as the inability to open or close the window, the window can be opened and closed better in an emergency. When the power fails or the controller fails to work, and the chain does not move and the window cannot be opened or closed, the motor is separated from the reduction mechanism by turning on the clutch device, so that the window can be opened easily, and the window can also be fixed to any position. At any angle, the hand-operated device is used for heavy windows. When it is necessary to use electric power, it only needs to close the clutch device. After reset, it will not affect the control of the electric system
