Description
Technical field
The present invention relates to the parts of window opener, particularly relate 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, for the high-tech product of building trade.Window opener from
Divide in Mechanical Driven mode and have 3 types, toothed bar type window latch, screw type window latch and crank arm type window opener.
Existing crank arm type window opener includes the rotating shaft being fixed on window frame, and rotating shaft is fixed some push-pull arms, push-and-pull
Arm with carry out hinged with the hinged strut of sash, the wherein hinged push rod of a push-pull arm, push rod and drive mechanism
Connect, drive structure to drive push rod to drive push-pull arm push-pull arm to swing, thus realize the open and close of window.
Push-pull arm on existing crank arm type window opener is during push-and-pull, and strut or push rod connect with push-pull arm
Synapsis offsets, thus limits the angle of the unlatching of window, and on the other hand, strut or push rod be long-time and push-and-pull
Arm offsets, and is easily damaged strut, push rod and push-pull arm, reduces service life.
Summary of the invention
For solving above-mentioned technical problem, it is an object of the invention to provide one and can increase open angle of window, make
Push-pull arm by life-span length.
The crank arm type window opener handle of cranking arm of the present invention, including two ends have connect end handle body, two
Connecting end and be respectively the first connection end, the second connection end, described first connects end in " recessed " type, its diapire
Being provided with and be perpendicular to the described first inclined-plane connecting end two side, described second connects end has and described handle
The axis hole that body is vertical.
Further, described inclined-plane from described first connect end diapire in the middle part of to the sloped-end of its diapire,
The angle of inclination on described inclined-plane is 40 °～50 °.
Further, the described first two side connecting end 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, the crank arm type window opener of the present invention with handle of cranking arm by by handle body and strut
Or the contact position of push rod is set to inclined-plane, to improve the rotation amplitude of push rod, thus increase the opening angle of window；
Meanwhile, strut or push rod are that face contacts with the contact position of handle body, be effectively protected strut, push rod with
And handle body, extend service life, thus reduce the use cost of window opener.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technology of the present invention
Means, and can being practiced according to the content of specification, below with presently preferred embodiments of the present invention and coordinate attached
After figure describes in detail such as.
Accompanying drawing explanation
Fig. 1 is the structural front view of the present invention；
Fig. 2 is the structure top view of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is described in further detail.With
Lower embodiment is used for illustrating the present invention, but is not limited to the scope of the present invention.
See Fig. 1 and Fig. 2, a kind of crank arm type window opener handle of cranking arm described in a preferred embodiment of the present invention,
Have the handle body 10 connecting end including two ends, handle body 10 is in " " type, and two connect end is respectively
First connects end 20, second connects end 30.
In the present invention, the first connection end 20 is in " recessed " type, and its diapire is provided with and is perpendicular to the first connection end 20
The inclined-plane 21 of two side, and first connect end 20 two side be provided with connecting hole 22 in opposite directions.
Concrete, first connects the inclined-plane 21 on end 20 in the middle part of the first diapire connecting end 20 to its diapire
Sloped-end, the angle of inclination on inclined-plane 21 is 40 °～50 °, as the preferred embodiments of the present invention, this
The angle of inclination on inclined-plane 21 is set to 45 ° by invention.
First connection end 20 of handle body 10, for hinged with the strut of crank arm type window opener or push rod, has
In body is " recessed " type groove that the end of strut or push rod penetrates the first connection end 20, bolt is utilized to pass even
Connect the two side that strut or push rod and first connect end 20 by hole 22 hinged, make strut or the push rod can relative the
One connects end 20 pivots, because being provided with inclined-plane 21, when strut or push rod exist on the first diapire connecting end 20
When rotating on the first connection end 20, strut or push rod can be resisted against on this inclined-plane 21, compare strut or push away
Bar is resisted against on the diapire of level, and the amplitude that strut or push rod can be made against inclined-plane 21 to rotate increases by 45 °, drives
Motivation structure is driving push rod, and push rod can significantly rotate, thus increases the opening angle of window.
It addition, it is face contact that strut or push rod are resisted against on inclined-plane 21, and strut or push rod offset with plane,
When rotating, being point cantact, at contact point, strut or push rod and handle body 10 are the most damaged,
And face contact, add the contact area of strut or push rod and inclined-plane 21, strut or push rod can be avoided and push away
Damaged for body 10, extend service life, thus reduce the use cost of window opener.
The present invention has the axis hole 31 vertical with handle body 10 on the second connection end 30 of handle body 10,
Handle body 10 is located in the rotating shaft of window opener will pass through axis hole 31.
For the rotating shaft of handle body 10 with window opener is fixed, in the present invention on the sidewall of axis hole 31
Being provided with two fixing holes 32, two fixing holes 32 are screwed hole.After handle body 10 is through in rotating shaft, profit
It is locked in fixing hole 32 with jackscrew, and holds out against rotating shaft, thus realize being fixed in rotating shaft handle body 10,
Make the handle body 10 can be with axis of rotation.
The crank arm type window opener of the present invention uses handle of cranking arm by by handle body and strut or the contact position of push rod
It is set to inclined-plane, to improve the rotation amplitude of push rod, thus increases the opening angle of window；Meanwhile, strut or
Push rod is that face contacts with the contact position of handle body, is effectively protected strut, push rod and handle body,
Extend service life, thus reduce the use cost of window opener.
The above is only the preferred embodiment of the present invention, is not limited to the present invention, it is noted that
For those skilled in the art, on the premise of without departing from the technology of the present invention principle, also
Can make some improvement and modification, these improve and modification also should be regarded as protection scope of the present invention.
