Description

A kind of crank arm type window opener handle of cranking arm

Technical field

The utility model relates to the parts of window opener, particularly relates to a kind of crank arm type window opener handle of cranking arm.

Background technology

Window opener is the machine for opening and closing window, is the high-tech product of building trade.Window opener has 3 types, toothed bar type window latch, screw type window latch and crank arm type window opener from Mechanical Driven mode point.Existing crank arm type window opener comprises the rotating shaft be fixed on window frame, rotating shaft is fixed some push-pull arms, push-pull arm carries out hinged with the strut hinged with sash, the wherein hinged push rod of a push-pull arm, push rod is connected with driving mechanism, drives structure drives push rod to drive push-pull arm push-pull arm to swing, thus realizes the open and close of window.

Push-pull arm on existing crank arm type window opener is in push-and-pull process, and the contact position of strut or push rod and push-pull arm offsets, thus the angle of the unlatching of restriction window, on the other hand, strut or push rod are long-time to offset with push-pull arm, easily damages strut, push rod and push-pull arm, minimizing application life.

Utility model content

For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of push-pull arm increasing open angle of window, long service life.

Crank arm type window opener handle of cranking arm of the present utility model, comprise the handle body that two ends have link, two links are respectively the first link, the second link, described first link is in " recessed " type, its diapire is provided with the inclined-plane perpendicular to described first link two side, and described second link has the axis hole vertical with described handle body.

Further, described inclined-plane is to the sloped-end of its diapire in the middle part of the diapire of described first link, and the angle of inclination on described inclined-plane is 40 ° ~ 50 °.

Further, the two side of described first link is provided with connecting hole in opposite directions.

Further, the sidewall of described axis hole is provided with two fixing holes.

Further, fixing hole described in two is screwed hole.

Further, described handle body is in " ﹀ " type.

By such scheme, crank arm type window opener of the present utility model by the contact position of handle body and strut or push rod is set to inclined-plane, to improve the rotation amplitude of push rod, thus increases the opening angle of window with handle of cranking arm; Meanwhile, strut or push rod are that face contacts with the contact position of handle body, effectively protect strut, push rod and handle body, extend application life, thus reduce the use cost of window opener.

Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of manual, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.

Accompanying drawing explanation

Fig. 1 is structural front view of the present utility model;

Fig. 2 is structure top view of the present utility model.

Detailed description of the invention

Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.

See Fig. 1 and Fig. 2, a kind of crank arm type window opener handle of cranking arm described in the utility model one preferred embodiment, comprise the handle body 10 that two ends have link, handle body 10 is in " ﹀ " type, and two links are respectively the first link 20, second link 30.

In the utility model, the first link 20 is in " recessed " type, and its diapire is provided with the inclined-plane 21 perpendicular to the first link 20 two side, and the two side of the first link 20 is provided with connecting hole 22 in opposite directions.

Concrete, inclined-plane 21 on first link 20 in the middle part of the diapire of the first link 20 to the sloped-end of its diapire, the angle of inclination on inclined-plane 21 is 40 ° ~ 50 °, as preferred embodiment of the present utility model, in the utility model, the angle of inclination on inclined-plane 21 is set to 45 °.

First link 20 of handle body 10 is for hinged with the strut or push rod of crank arm type window opener, specifically the end of strut or push rod is penetrated in " recessed " type groove of the first link 20, bolt is utilized to pass connecting hole 22 by hinged for the two side of strut or push rod and the first link 20, make strut or push rod can relative first link 20 pivotable, because the diapire of the first link 20 is provided with inclined-plane 21, when strut or push rod rotate on the first link 20, strut or push rod can be resisted against on this inclined-plane 21, compare and strut or push rod are resisted against on the diapire of level, the amplitude that strut or push rod can be made against inclined-plane 21 to rotate increases by 45 °, driving mechanism is at driving push rod, push rod can significantly rotate, thus increase the opening angle of window.

In addition, it is face contact that strut or push rod are resisted against on inclined-plane 21, and strut or push rod and plane offset, when rotation, it is point cantact, at contact point place, strut or push rod and handle body 10 easily damaged, and face contact, add the contact area on strut or push rod and inclined-plane 21, strut or push rod and handle body 10 can be avoided damaged, extend application life, thus reduce the use cost of window opener.

In the utility model handle body 10 the second link 30 on there is the axis hole 31 vertical with handle body 10, to be located in the rotating shaft of window opener by handle body 10 by axis hole 31.

For the rotating shaft of handle body 10 with window opener being fixed, on the sidewall of axis hole 31, be provided with two fixing hole 32, two fixing holes 32 in the utility model is screwed hole.Handle body 10 is being through after in rotating shaft, is utilizing jackscrew to be locked in fixing hole 32, and hold out against rotating shaft, thus realizing handle body 10 to be fixed in rotating shaft, making handle body 10 can with axis of rotation.

Crank arm type window opener of the present utility model by the contact position of handle body and strut or push rod is set to inclined-plane, to improve the rotation amplitude of push rod, thus increases the opening angle of window with handle of cranking arm; Meanwhile, strut or push rod are that face contacts with the contact position of handle body, effectively protect strut, push rod and handle body, extend application life, thus reduce the use cost of window opener.

The above is only preferred embodiment of the present utility model; be not limited to the utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
