Problems solved by technology
[0003] During the push-pull process of the push-pull arm on the existing crank-arm type window opener, the contact point between the strut or push rod and the push-pull arm is offset, thereby limiting the opening angle of the window. On the other hand, the strut or push rod will Offset against the push-pull arm, it is easy to damage the strut, push rod and push-pull arm, reducing the service life

Embodiment Construction
[0015] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0016] see figure 1 with figure 2 , a crank arm push handle for a crank arm type window opener according to a preferred embodiment of the present invention, includes a push handle body 10 with connecting ends at both ends, the push handle body 10 is in the shape of "﹀", and the two connecting ends are respectively The first connection end 20 and the second connection end 30 .
[0017] In the present invention, the first connection end 20 is in a "concave" shape, and the bottom wall is provided with inclined surfaces 21 perpendicular to the two side walls of the first connection end 20, and the two side walls of the first connection end 20 are provided with opposite conn...

The invention relates to a crank arm push handle for a crank arm type window opener. The crank arm push handle for the crank arm type window opener comprises push handle body with connecting ends at the two ends, the two connecting ends are a first connecting end and the second connecting end, the first connecting end is in an 'ao' character shape, the bottom wall of the first connecting end is provided with an inclined face perpendicular to the two side walls of the first connecting end, and the second connecting end is provided with a shaft hole perpendicular to the push handle body. According to the crank arm push handle for the crank arm type window opener, through the mode that the contact portion of the push handle body and a supporting rod or a push rod is arranged to be the inclined face, the rotating range of the push rod is improved, and therefore the opening angle of a window is increased; meanwhile, the contact portion of the supporting rod or the push rod and the push handle body is in face contact, the supporting rod, the push rod and the push handle body are effectively protected, the service life is prolonged, and therefore the use cost of the window opener is reduced.
Description
technical field [0001] The invention relates to components of a window opener, in particular to a crank arm push handle for a crank arm type window opener. Background technique [0002] The window opener is a machine used to open and close windows, which is a high-tech product in the construction industry. There are three types of window drives in terms of mechanical drive methods, rack type window drives, screw type window drives and crank arm type window drives. The existing crank arm type window opener includes a rotating shaft fixed on the window frame, on which a number of push-pull arms are fixed, and the push-pull arms are hinged with the struts hinged with the window sash, wherein one of the push-pull arms is hinged with a push rod, and the push rod and the drive The mechanism is connected, and the driving structure drives the push rod to drive the push-pull arm to swing, thereby realizing the opening and closing of the window. [0003] During the push-pull process...
