Problems solved by technology
[0004] For example, the Chinese invention patent CN204627267U discloses a manual and electric dual-purpose window opener. When the electric drive window opening of the window opener is converted into a manual drive window opener, the bevel gear of the manual crank is moved from the hole on the side of the housing. Pressing in, the bevel gear presses the bevel gear of the coupling shaft, which will separate the coupling from the output shaft of the electric drive. When the window is opened by manual drive and turned by electric drive, the manual handle needs to be pulled out, and the manual handle is disengaged from the window opening machine. , easy to lose, when you need to use it, you have to look for the manual crank handle, which is very inconvenient to use

Embodiment Construction
[0021] Embodiments of the technical solution of this embodiment will be described in detail below in conjunction with the accompanying drawings. The following embodiments are only used to illustrate the technical solution of this embodiment more clearly, so they are only examples, and should not be used to limit the protection scope of this embodiment.
[0022] Such as Figure 1-Figure 4 As shown, the embodiment of the present invention provides an electric and manual convertible chain window opener, including a chain window opener 10, a transmission mechanism 20, a motor 30 that drives the chain window opener 10 to open and close windows through the transmission mechanism 20, and a shaker. handle 40 , locking mechanism 50 and spring mechanism 60 .
[0023] The motor 30 is a geared motor, and the output shaft of the motor 30 is coaxially fixed with a first gear 31 . The output shaft of the crank 40 is perpendicular to the output shaft of the motor 30 , and a first bevel gear...

The invention discloses a chain window opener with an electric and manual switching function. The chain window opener comprises a chain window opener body, a transmission mechanism, a motor and a crank. A first gear is fixed to an output shaft of the motor. A first bevel gear is fixed to an output shaft of the crank. The transmission mechanism comprises a first transmission rod and a movable shaftrod. One end of the first transmission rod and the input end of the chain window opener body are in transmission connection. A second gear is fixed to the other end of the first transmission rod. A tooth shaft and a second bevel gear are rotationally mounted on the movable shaft rod and are fixedly connected, and the movable shaft rod can do reciprocating motion in the axial direction. The toothshaft is kept engaged with the second gear all the time. When the tooth shaft is engaged with the first gear, the second bevel gear is separated from the first bevel gear, and when the tooth shaft isseparated from the first gear, the second bevel gear is engaged with the first bevel gear. According to the chain window opener, electric driving window opening and hand-cranking driving window opening can be converted, and it is ensured that a window can be opened and closed in a hand cranking manner during a power failure.
Description
technical field [0001] The invention relates to the technical field of window drives, in particular to an electric and manual switchable chain window drive. Background technique [0002] A window opener is a device used to open and close windows. The window openers currently on the market include manual window openers and electric window openers. With the development of smart homes, the requirements for electric window openers are also increasing. It is getting higher and higher. Although it is convenient to open the window automatically, in real life, it is inevitable that there will be a power outage. Running into the above situation will cause great loss to the user, even personal safety injury. [0003] In order to solve the above-mentioned problems, some electric window drivers on the market are provided with a hand-operated device, which converts the electric drive to open the window into the manual drive to open the window when the power is cut off. [0004] For exa...
