Abstract

The invention relates to an electric window opening machine capable of being operating manually. The electric window opening machine capable of being operating manually includes a shell body, a reducing mechanism and a wheel chain which are mounted in the shell body, the reducing mechanism is a multiple-level gear transmission mechanism, a transmission gear of the last level of the reducing mechanism is coaxially in transmission with the chain wheel through a transmission shaft, one end of the transmission shaft is fixed to the shell body through an elastomer and is slidably arranged between the transmission gear and the chain wheel through the elastomer, and the elastomer can separate the transmission shaft from the driving gear or the chain wheel through stretching and deforming. The electric window opening machine can switch to a manual operation mode conveniently.

Description

technical field [0001] The invention relates to the technical field of five building accessories, in particular to a manually operable electric window opener. Background technique [0002] The window opening machines currently on the market usually drive the sprocket to rotate through the motor, retract and release the chain, and realize the window opening and closing actions. The motor and the sprocket are connected through a reduction mechanism, and the reduction mechanism is generally a multi-stage gear structure. [0003] At present, the window machines generally have the following disadvantages: [0004] When the motor is powered off, the user cannot manually operate the window to open and close the window because the main body and the power output end of the window opener are directly connected to the window frame and sash. Inconvenience or loss, which will obviously cause inconvenience to people's normal use. Contents of the invention [0005] The present inventio...
