Deng generation movement interference, avoid that abnormal sound and other failure conditions occur in moving process.Wherein in closing position, the meeting of turning arm 42
Movement interference occurs with the adjusting nut 50 of rotating connector 46, so as to realize the spacing of closing position.
Embodiment two：
As shown in Figure 29 and Figure 30, a kind of range hood is present embodiments provided, the difference of itself and embodiment one exists
In the structure of hinge.
In the present embodiment, hinge includes connector 40 and torsion spring 41.Wherein, connector 40 is provided with and is fixedly connected with portion 401,
It is fixedly connected with outer exhaust fume collecting hood 2；Rotating junction 400 is additionally provided with connector 40, outer exhaust fume collecting hood 2 is provided with axis hole, the company of rotation
Socket part 400 is arranged in axis hole and can rotated in axis hole, so that upper door panel assemblies 1 being capable of rotating opening, closing（Upper door-plate
State when component 1 is opened is as shown in figure 30, and state when upper door panel assemblies 1 are closed is as shown in figure 29）；Also set on connector 40
There is torsion spring connecting portion 402, the first end arms 410 of torsion spring 41 is connected with outer exhaust fume collecting hood 2, the second end arms 411 and torsion spring connecting portion
402 are connected, and torsion spring 4 is in the state being compacted.
Wherein, in upper door panel assemblies 1 rotate moving process, the torsion spring connecting portion 402 on connector 40 moves therewith, makes
The link position P of torsion spring connecting portion 402 and the second end arms 411 of torsion spring 41 moves to another from the side of rotating junction 400
Side so that the direction that torsion spring 41 is applied to the power of door panel assemblies 1 changes, and then causes torsion spring 41 to be applied to door-plate group
The direction of the torque of part 1 changes so that the power-assisted that upper door panel assemblies 1 can be applied when opening and closing by torsion spring 41.
Specifically, as shown in figure 29, under the upper closure state of door panel assemblies 1, link position P is located at rotating junction 400
Right side, the direction for the power F that the torsion spring 41 that is compacted applies as shown in FIG., in the presence of power F and arm of force L, torsion spring 41
1 clockwise torque of door panel assemblies is applied to, contributes to upper door panel assemblies 1 to be maintained at closure state, while the torque
It can prevent door panel assemblies 1 from loosening, arbitrarily opening etc. occurs because of vibrations.
As shown in figure 30, when upper door panel assemblies 1 are opened, link position P is located at the left side of rotating junction 400, is pressed
As shown in FIG., in the presence of power F ' and arm of force L ', torsion spring 41 is applied in the direction for the power F ' that tight torsion spring 41 applies
1 anticlockwise torque of door panel assemblies, contributes to upper door panel assemblies 1 to open and is maintained at open mode.
In upper door panel assemblies 1 during the closed mode shown in Figure 29 turns to the open mode shown in Figure 30, when upper
Door panel assemblies 1 turn to postcritical（That is the link position P of the second end arms 411 of torsion spring connecting portion 402 and torsion spring 41 is from turning
Separation of the side of rotation connection 400 to opposite side）Afterwards can by torsion spring 41 apply support force, the support force contribute to by
Upper door panel assemblies 1 are maintained at open mode.The pass shown in Figure 29 is turned to from the open mode shown in Figure 30 in upper door panel assemblies 1
During closed state, it can be helped after upper door panel assemblies 1 turn to postcritical by the closing force of the application of torsion spring 41, the closing force
Keep closing in upper door panel assemblies 1.
It should be noted that the torsion spring of the present embodiment is in impaction state is in the one of rotating junction with link position P
The position of side is engaged so that the torque that torsion spring applies can provide power-assisted when opening and closing.It is of course also possible to torsion is set
Spring is in extended state, and now link position P is located at the opposite side of rotating junction accordingly, and the torsion spring now stretched remains to
Power-assisted is provided which during opening and closing.
Although the embodiment disclosed by the utility model is as above, described content is only to readily appreciate the utility model
And the embodiment used, it is not limited to the utility model.Technical staff in any the utility model art,
On the premise of not departing from the spirit and scope disclosed by the utility model, it can be carried out in the form and details of implementation any
Modification and change, but scope of patent protection of the present utility model, must still be defined by appended claims and be defined.
