The distance of the 41 to the second articulated section of drive shaft 23 is equal to the distance that third articulated section 25 is arrived in the first articulated section 15；Driving
The distance of the 41 to the first articulated section of axis 15 is equal to the distance that third articulated section 25 is arrived in the second articulated section 23.That is, drive shaft 41, second
The axle center of articulated section 23, third articulated section 25 and the first articulated section 15 projects to form parallelogram sturcutre, so that driving
The rotation angle of axis 41 and the folding angle of air door 1 are identical, further improve the precision that control air door 1 opens and closes angle, from
And improve the precise degrees of control air quantity.
Can also by the distance of the 41 to the second articulated section of drive shaft 23, first articulated section 15 to third articulated section 25 away from
With a distance from, the 41 to the first articulated section of drive shaft 15 and the distance of the second articulated section 23 to third articulated section 25 is set as other ratios
Example, by the way that the rotation ratio of the rotation angle of drive shaft 41 and the folding angle of air door 1 is calculated, equally can achieve accurate control
Air door 1 processed opens and closes the effect of angle.Also, pass through control ratio, it may be convenient to be adapted to the demand of installation space.
At least one in first articulated section 15, the second articulated section 23 and third articulated section 25 is to snap connection axis.Such as Fig. 2
And shown in Fig. 3, by taking the second articulated section 23 as an example, the second articulated section 23 is the axis that snaps connection being set on intermediate connecting rod 2, driving
Connection through-hole is provided on connecting rod 3.When drive link 3 and intermediate connecting rod 2 are hinged, the second articulated section 23 is worn by flexible deformation
The connection through-hole overdrived on connecting rod 3, and hingedly positioned with through-hole is connect.By above-mentioned setting, facilitates intermediate connecting rod 2 and drive
The articulated connection of dynamic connecting rod 3.Second articulated section 23 can also be set in drive link 3, connection is provided on intermediate connecting rod 2
Through-hole.The second articulated section 23 can also be made to be independently arranged, connection through-hole is provided on drive link 3 and intermediate connecting rod 2, passes through
Second articulated section 23 sequentially passes through the two connection through-holes, realizes the hinged of drive link 3 and intermediate connecting rod 2.Similarly, first
Articulated section 15 and third articulated section 25 or above structure.
As shown in Figure 1 and Figure 6, it is preferable that air door 1 is provided with close to the side of the first articulated section 15 for fixing with air door
The check plate 11 of the inner wall location fit of frame 5.It is understood that the inner wall of air door fixed frame 5 is 5 court of air door fixed frame
To the one side of intermediate connecting rod 2, rotation drive device 4 and drive link 3.Air door 1 is to the outside of air door fixed frame 5 (far from intermediate
The direction of connecting rod 2, rotation drive device 4 and drive link 3) it opens, after opening to certain angle, check plate 11 and wind
The inner wall location fit of door fixed frame 5, avoids air door 1 and continues starting, effectively prevent the excessive feelings of 1 opening angle of air door
Condition.In the present embodiment, air door 1 is 90 ° relative to the maximum opening angle of air door fixed frame 5.
As shown in Fig. 1 and Fig. 4, the free ending tool of air door 1 has the closure for the outer wall location fit with air door fixed frame 5
Limit plate 12.The outer wall of air door fixed frame 5 is air door fixed frame 5 backwards to intermediate connecting rod 2, rotation drive device 4 and drive link 3
One side.When air door 1 is closed, it is closed the outer wall location fit of limit plate 12 and air door fixed frame 5, avoids the continuation of air door 1
Closure, effectively prevents air door 1 and is closed excessive situation.
In order to improve rotational stability of the drive link 3 relative to rotation drive device 4, drive link 3 further includes having
Disk connector 33, drive shaft jack 31 are arranged concentrically with disk connector 33.By above-mentioned setting, drive link 3 is improved
The rotation center of circle (33 position of disk connector) weight, and then improve drive link 3 relative to rotation drive device 4
Rotational stability.
In the present embodiment, there is the driving device being fixedly connected with the ontology of rotation drive device 4 on air door fixed frame 5
Box 54.That is, rotation drive device 4 is directly anchored in the driving device box 54 of air door fixed frame 5.It can also be solid by connector
Determine rotation drive device 4, e.g., rotation drive device 4 and air door fixed frame 5 be fixed on jointly in the shell of total-heat exchanger,
And then reach the relatively fixed of air door fixed frame 5 and rotation drive device 4.
The embodiment of the invention also provides a kind of total-heat exchanger, including air door mechanism, air door mechanism is as any of the above-described
Kind air door mechanism.Since above-mentioned air door mechanism has above-mentioned technique effect, the total-heat exchanger with above-mentioned air door mechanism is also answered
With same technical effect, no longer it is discussed in detail herein.
