Abstract
The utility model discloses a fan-leaf connection structure for a ceiling fan. A key point of the technical scheme is that: the fan-leaf connection structure comprises a casing and fan-leaves driven by a motor, the casing is fixedly connected with leaf fork feet, the head end of the fan-leaf is fixedly connected with leaf fork palms, the leaf fork feet are hinged to the leaf fork palms through pins. The hinge position between the leaf fork feet and the leaf fork palm is provided with a limit structure for rotating the fan-leaves on a horizontal direction and downward direction. The utility model solves problem that the present fan-leaf can not be folded, and is applied in the fan industry.
Description
[technical field]
The utility model relates to a kind of ceiling fan, relates to the linkage structure of flabellum specifically.
[background technique]
The linkage structure of existing flabellum and ceiling fan shell generally all is fixing dead, can not fold.Flabellum is installed on the shell of motor, and flabellum becomes to open level, from starting, run well, shutting down, can not change form.
[model utility content]
The utility model purpose be overcome deficiency of the prior art and provide a kind of flabellum can be downwards automatically gathering, reliable performance, take up room the flabellum linkage structure little.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposal:
The flabellum linkage structure that is used for ceiling fan is characterized in that including shell and flabellum by driven by motor, is fixedly connected with leaf hairpin pin on shell, is fixedly connected with the leaf hairpin palm at the head end of flabellum, and is hinged by pin between the described leaf hairpin pin and the leaf hairpin palm.
The aforesaid flabellum linkage structure that is used for ceiling fan, the hinged place that it is characterized in that described leaf hairpin pin and the leaf hairpin palm are provided with the limit structure that flabellum can only be in the horizontal direction rotated with vertical downward direction.
The aforesaid flabellum linkage structure that is used for ceiling fan, it is characterized in that described limit structure includes a straight flange and the slip surface that is located at leaf hairpin foot portion of leaf hairpin foot portion, described slip surface and straight flange are together adjacent, the upper end portion of described slip surface is plane always, and the underpart of slip surface is an arc surface.
The aforesaid flabellum linkage structure that is used for ceiling fan, it is characterized in that the leaf hairpin palm be respectively equipped with spring button screw above the leaf hairpin pin, between two spring button screws, be provided with the extension spring that the available buffer flabellum draws in downwards.
Tractive force when the aforesaid flabellum linkage structure that is used for ceiling fan, the pulling force that it is characterized in that described extension spring are drawn in downwards under the self gravitation effect less than flabellum.
The utility model compared with prior art has following advantage: the utility model is hinged together by the leaf hairpin pin and the leaf hairpin palm, makes it to realize rotating.Having leaf hairpin pin and leaf hairpin to slap hinged end again is a straight flange, and the hinged upper end portion of the leaf hairpin palm and leaf hairpin pin is a straight flange in addition, and the hinged underpart of the leaf hairpin palm and leaf hairpin pin is the circular arc limit.Flabellum can down draw under the self gravitation effect like this.And after flabellum opened, because the end of leaf hairpin pin is a straight flange, leaf hairpin palm end was a straight flange, and then flabellum can be toward upwarping.The posterior lobe hairpin palm is provided with extension spring with leaf hairpin pin, when fan is shut down, plays the effect that the buffering flabellum draws in.

[embodiment]
Below in conjunction with accompanying drawing the utility model is described in detail:
The flabellum linkage structure that is used for ceiling fan includes shell 1 and flabellum 2 by driven by motor.
Described leaf hairpin pin 11 is a square block with the leaf hairpin palm 21 joints that are connected, and the leaf hairpin palm 21 joints that are connected with leaf hairpin pin 11 are square groove, and square block inserts in the square groove and by pin 31 and pins.Make it leaf hairpin pin 11 and the leaf hairpin palm 21 and rotate up and down realizing only, and limit the rotation of left and right direction.
The hinged place of described leaf hairpin pin 11 and the leaf hairpin palm 21 is provided with the limit structure 3 that flabellum 2 can only be in the horizontal direction rotated with vertical downward direction.Described limit structure 3 includes a straight flange 32 of leaf hairpin pin 11 ends and is located at the slip surface of leaf hairpin pin 11 ends, and described slip surface and straight flange 32 are together adjacent, and the upper end portion of described slip surface is plane 33 always, and the underpart of slip surface is an arc surface 34.
When fan begins outage when stopping because the tractive force of the pulling force of extension spring 36 when under the self gravitation effect, drawing in downwards less than flabellum 2, so flabellum 2 under the gravity of himself, down gathering of flabellum 2 beginnings.Because the underpart of slip surface is an arc surface 34, so flabellum 2 can freely down draw in, when fan was static, flabellum 2 was folded into 90 degree downwards.
The leaf hairpin palm 21 be respectively equipped with spring button screw 35 above the leaf hairpin pin 11, between two spring button screws 35, be provided with the extension springs 36 that available buffer flabellum 2 draws in downwards.
When fan running, owing under a little the effect of pulling force of the centrifugal force that produces when rotating and extension spring 36, flabellum 2 is outwards opened till flabellum 2 opens level fully gradually.When shutting down, flabellum 2 is subjected to the effect of gravity, draws in downwards.Because the pulling force of extension spring 36 plays the effect of buffering, the downward gathering that flabellum 2 will be slowly is up to vertical fully 90 degree.Characteristics of the present utility model are dynamic strong, and from the starting of fan, run well, shut down, each process, the form of flabellum 2 are all in continuous variation, and difform flabellum can produce different dynamic effects! And in change procedure, can not produce noise.
