The utility model proposes a kind of luffing mechanism, which is used for electric fan 100.
It please refers to Fig.4 and Fig. 5, in one embodiment of the utility model, the luffing mechanism includes：
Connecting shaft 10；
First supporting rack 30, the connecting shaft 10 are rotationally connected with first supporting rack 30；
Runner assembly 50, the runner assembly 50 are sheathed on the connecting shaft 10, and the runner assembly 50 includes rotating member
51 and the sliding part 53 that is rotatablely connected with rotating member 51, the rotating member 51 is convexly equipped with first end face close to the end face of sliding part 53
Tooth 511, the sliding part 53 are convexly equipped with and 511 matched second end face of first end face tooth close to the end face of the rotating member 51
Tooth 531, the rotating member 51 are rotatablely connected with the connecting shaft 10, and are connect with first supporting rack 30, the sliding part
53 are slidably connected with the connecting shaft 10；And
Elastic component 70, the elastic component 70 are sheathed on the connecting shaft 10, and set on the sliding part 53 far from rotating member
51 one end, one end of the elastic component 70 are connect with the sliding part 53, and the other end is connect with the connecting shaft 10, works as institute
When stating rotating member 51 and driving first supporting rack 30 to rotate under the effect of external force, the first end face tooth 511 opposite second
End-tooth 531 rotates, and the sliding part 53 is slided far from rotating member 51, described when the first end face tooth 511 stops operating
Sliding part 53 is slided towards the rotating member 51 until being adjacent to the rotating member 51 by the active force of elastic component 70.
Specifically, the first supporting rack 30 is rotatablely connected with connecting shaft 10, herein, connecting shaft 10 is fixed, first
Support 30 is rotatable around connecting shaft 10.Rotating member 51 is connect with the first supporting rack 30, and connection here is is detachably connected or consolidates
Fixed connection, such as be buckled or be spirally connected or weld.Rotating member 51 is rotatablely connected with connecting shaft 10, it is possible to understand that, due to connecting shaft
10 is fixed, and rotating member 51 is sheathed on connecting shaft 10, is equipped with the joint face being rotatably assorted with connecting shaft 10 in rotating member 51, such as
Arc surface, rotating member 51 can 360 degree rotations.Sliding part 53 is slidably connected with connecting shaft 10, sliding since connecting shaft 10 is fixed
Moving part 53 is sheathed on connecting shaft 10, and the joint face being slidably matched with connecting shaft 10, such as sliding rail are equipped in sliding part 53.Rotating member 51
First end face tooth 511 is convexly equipped with close to the end face of sliding part 53, sliding part 53 is convexly equipped with and first close to the end face of rotating member 51
511 matched second end face tooth 531 of end-tooth, the end-tooth that first end face tooth 511 and second end face tooth 531 have is more, fixed
Parallactic angle degree is more, and in the present embodiment, first end face tooth 511 and second end face tooth 531 are respectively provided with 36 end-tooths, and rotating member 51 can be determined
Position can be positioned to often 10 degree of rotation, be equivalent to 36 rotation gears.
Furthermore, it is necessary to explanation, based on above structure, elastic component 70 is preferably compressed spring, and elastic component 70 is limited
Between connecting shaft 10 and sliding part 53, elastic component 70 is in compressive state always so that elastic component 70 is by rotating member 51
To can further be compressed during the thrust of sliding part 53, when rotating member 51 stops operating, due to elastic component 70, there are one rebound
Power, and then 53 1 deboosts of sliding part are applied to, make the second end face tooth 531 of sliding part 53 and the first end of rotating member 51
Face tooth 511 matches.
Accordingly, it is to be understood that, the technical solution of the utility model, electric fan 100 when in use, the machine of electric fan 100
First 110 are installed on the first supporting rack 30, due to first end face tooth 511 be set on rotating member 51, can with the rotation of rotating member 51 and
Rotation, second end face tooth 531 are set on sliding part 53, and sliding part 53 can only be slided with connecting shaft 10, and cannot be rotated, and work as rotation
When part 51 drives the rotation of the first supporting rack 30 under the effect of external force, 511 opposing second end face tooth 531 of first end face tooth rotates,
At this point, first end face tooth 511 is applied to 531 1 thrusts far from rotating member 51 of second end face tooth, sliding part 53 is along connection
Axis 10 slides, and far from rotating member 51, head 110 is with rotation；When rotating member 51 turns to suitable position, sliding part 53 by
The thrust of elastic component 70 is moved to close to the direction of rotating member 51, until first end face tooth 511 coordinates with second end face tooth 531,
Rotating member 51 is adjacent to sliding part 53, and head 110 is positioned in designated position, which passes through first end face tooth 511,
The quantity for coordinating the pitching operation for completing electric fan 100, reducing elastic component of biend tooth 531 and elastic component 40, and due to
The angle that end-tooth can position is more, and head 110 operates steadily in rotation, and then extends the service life of electric fan 100.
Please refer to Fig. 6 to Fig. 9, in one embodiment of the utility model, the first end face tooth 511 is wavy shaped configuration, fixed
The justice first end face tooth 511 is first end face tooth 511 along the distance that the central axial direction of the rotating member 51 extends
The value range of height h1, h1 are 0.5mm≤h1≤2.0mm, and the second end face tooth 531 is wavy shaped configuration, described in definition
Height h2 of the distance that second end face tooth 531 extends along the central axial direction of the sliding part 53 for second end face tooth 531,
The value range of h2 is 0.5mm≤h2≤2.0mm.
It should be understood that it is wavy shaped configuration by first end face tooth 511, comparative resistance is small when rotating rotating member 51, required
The external force to be applied is little, in addition, first end face tooth 511 is set as along the height h1 of the central axial direction of rotating member 51
0.5mm≤h1≤2.0mm when being rotated due to rotating member 51, can be applied to 53 1 pushing away far from 51 direction of rotating member of sliding part
Power, sliding part 53 is 0.5mm≤h2≤2.0mm along the displacement h2 that connecting shaft 10 is slided, when rotating member 51 rotates, first end face
Tooth 511 is ceaselessly separate and close with second end face tooth 531, and maximum distance is first end face between rotating member 51 and sliding part 53
The sum of tooth 511 and the height of second end face tooth 531, the i.e. distance of 1mm~4mm, comparatively, the power variation of compression elastic piece 70
Also it is small, 70 stable movement of sliding part 53 and elastic component, because the compression variation amount of compression elastic piece 70 is small, the compression time of elastic component 70
The more service lifes of number are long, also extend the service life of electric fan 100.Second end face tooth 531 be and 511 phase of first end face tooth
The structure matched.
Fig. 5 and Fig. 9 are please referred to, the connecting shaft 10 is semicircle, institute close to the cross section of one end of the rotating member 51
State sliding part 53 and include the first noumenon 533, the first noumenon 533 is sheathed on the connecting shaft 10, and with the connecting shaft 10
It is slidably connected, the end cross-sectional of the first noumenon 533 is and the 10 matched semicircle of connecting shaft.
