Specific implementation mode
The utility model is described further with reference to the accompanying drawings and examples.
With reference to Fig. 2 and Fig. 3, this double-crank link-type active link device includes：Bottom plate 1 for connecting window frame, is used for
Support the trailing arm 4 of sash, long crank connecting link 2, short crank connecting link 5, the long crank connecting link 2 and the short crank connecting link 5 difference
It is articulated between the bottom plate 1 and the trailing arm 4, the trailing arm 4 is arranged for the long crank connecting link 2 to be limited in first turn
The positioning convex portion for short crank connecting link 5 to be limited in the second rotational angle is arranged in the positioning convex portion 42 of dynamic angle, the bottom plate 1
12。
It is all hinged between each component of above-mentioned double-crank link-type active link device, without slide unit, Neng Gouyou
Effect avoids the problem that traditional sliding support is susceptible to sliding and is obstructed.Meanwhile in the positioning convex portion 42 and bottom plate 1 on above-mentioned trailing arm 4
Positioning convex portion 12 constitutes double locating structure, and compared to single location structure, this double locating structure can effectively decompose single fixed
The impact force that site is received, so as to extend its service life.When long crank connecting link 2 is in the first angle of rotation in exemplary embodiments
Degree, short crank connecting link 5 sash in the second rotational angle are opened in 90 degree of states, it will be appreciated by those skilled in the art that this reality
It is not limited to this with novel, can carry out respective design to the position of positioning convex portion as needed makes the maximum opening angle of sash
It meets the requirements.
Offset plate 3 further is fixedly mounted at the top of the bottom plate 1, the offset plate 3 and the long song when sash is closed
The friction of handle connecting rod 2 holds up long crank connecting link 2.The support force of long crank connecting link 2 can be decomposed in this way, reduced sash and closed at present
Pendant degree.
Using being hinged between rivet realization component in above-described embodiment.Specifically, the long crank connecting link 2 passes through two
Rivet 61,64 is hinged with the bottom plate 1 and the trailing arm 4 respectively, and the short crank connecting link 5 passes through other two rivet 62,63
It is hinged with the bottom plate 1 and the trailing arm 4 respectively, plastic washers 7 are set between each metalwork of articulated section, to prevent metal
Abrasion.
By taking rivet 61 as an example, further step 61 ', the step 61 ' and the modeling of rivet are formed in the root of rivet 61
The hole portion of rubber gasket 7 matches, and can avoid riveting unstable problem caused by plastic washers deformation when riveting.
The end of above-mentioned rivet 63,64 is from place connecting rod（Short crank connecting link 5）Surface protrude the abutting to be formed to fan frame
Portion, in this way after being fixed short crank connecting link 5 and fan frame by mounting hole 41,42 with screw, abutting part forms pressure to fan frame,
Short crank connecting link 5 is set locally to generate stress, can prevent from opening repeatedly because of sash leads to loosened screw.
For the ease of riveting processing and increase bonding strength, further connects in the long crank connecting link 2 and the short crank
The oral area of riveted holes on bar 5 is formed with chamfering.
The mounting hole 11 and the riveted holes of bottom plate 1 and connecting rod of further bottom plate 1 on the same line, can not keep bottom plate
Intensity reduces bottom deformation.
The pin hole 13 for installing spacer pin further is set close to the junction of the short crank connecting link 5 on bottom plate 1,
The spacer pin is used to the short crank connecting link 5 being limited in third rotational angle.By installing spacer pin in pin hole 13, with institute
It states the cooperation of short crank connecting link 5 and short crank connecting link 5 is limited in third rotational angle, opened so as to which sash is fixed on second
State is opened, the state at 30 degree is such as opened.
State of the above-mentioned double-crank link-type active link device after window closing is shown in Fig. 4.Reference Fig. 4,
Under closed state, the first straight line where the first hinge joint 10 and the second hinge joint 20 and the first hinge joint 10 and third hinge joint
For the angle a between second straight line where 30 between 1 degree to 10 degree, first hinge joint 10 is trailing arm 4 and short crank
The hinge joint of connecting rod 5, second hinge joint 20 are the hinge joint of long crank connecting link 2 and bottom plate 1, and the third hinge joint 30 is
The hinge joint of short crank connecting link 5 and bottom plate 1.The above-mentioned angle of traditional sliding support is 0 degree.Above-mentioned double-crank link-type activity chain tipping
It sets after increasing this angle, opens more smooth.
The utility model is described in detail above by specific embodiment, these detailed description are only limited to
