Abstract
The utility model relates to a limit device for a swinging fan blade in an air-conditioner. The limit device comprises a swinging fan blade and an air outlet frame; connecting posts are arranged at two ends of the swinging fan blade; positioning holes are formed on two sides of the air outlet frame; and the connecting posts are connected to the positioning holes. The limit device is characterized in that guide grooves are formed in the positioning holes of the air outlet frame; limit lug bosses are formed on the connecting posts; and the limit lug bosses are embedded in the guide grooves. Therefore, the control of the vertical swing precision can be realized only through the matching of the limit lug bosses and the guide grooves, no high-precision stepping motor is required, and no extra manufacturing expense is needed; and the limit device is suitable for popularization in the field.
Description
Technical field
The utility model relates to a kind of fan blade device for limiting, relates in particular to a kind of air-conditioning pendulum fan blade device for limiting, belongs to household electrical appliance technical field.
Background technology
The interior all requisite pendulum fan blade that is equipped with of machine of air-conditioner generally sold of institute in the market just.The pendulum angle control of pendulum fan blade generally is to cooperate the pulse after switching on to control by automatically controlled plate write-in program, thereby realizes swinging up and down of fan blade.But, because pulse controlled precision is not very high, fan blade swing up and down the operational effect that tends to deviation occur and influence air-conditioning.Simultaneously, if adopt the device of high accuracy control can increase the making burden of air-conditioning again, can't promote the use of.
Summary of the invention
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of air-conditioning pendulum fan blade device for limiting is provided.
For realizing the purpose of this utility model air-conditioning pendulum fan blade device for limiting, relate to pendulum fan blade, outlet frame, pendulum fan blade two ends are provided with joint pin, the both sides of outlet frame are distributed with locating hole, joint pin is connected into locating hole, wherein: be distributed with guiding groove on the described outlet frame locating hole, joint pin is provided with positive stop lug boss, and positive stop lug boss embeds in the guiding groove.
Further, above-mentioned air-conditioning pendulum fan blade device for limiting, wherein, described guiding groove is circular-arc, positive stop lug boss is provided with block tongue, the last end in contact of pendulum fan blade block tongue and circular-arc guiding groove when being bottom state, the following end in contact of block tongue and circular-arc guiding groove when putting fan blade and be last pendulum state.
Further, above-mentioned air-conditioning pendulum fan blade device for limiting, wherein, described joint pin is that " protruding " word shape connects plush copper, is provided with installing hole in the positive stop lug boss, connects plush copper and embeds in the installing hole.
Adopt technical solutions of the utility model, need not to use high-precision stepper motor can realize the pendulum fan blade is swung up and down the control of precision, only get final product by positive stop lug boss and cooperating of guiding groove.Simultaneously, can not increase extra manufacturing expense after adopting this structure, be fit to promote the use of in the art.
The purpose of this utility model, advantage and characteristics will illustrate by the non-limitative illustration of following preferential embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is the side surface configurations schematic diagram of outlet frame;
Fig. 2 is the enforcement schematic diagram of the pendulum fan blade bottom;
Fig. 3 is the enforcement schematic diagram of putting on the pendulum fan blade.
The implication of each Reference numeral is as follows among the figure:
1 pendulum fan blade, 2 outlet frames
3 guiding grooves, 4 positive stop lug boss
5 block tongues, 6 plush coppers
7 installing holes
The specific embodiment
Air-conditioning pendulum fan blade 1 device for limiting shown in Fig. 1～3, relate to pendulum fan blade 1, outlet frame 2, pendulum fan blade 1 two ends are provided with joint pin, the both sides of outlet frame 2 are distributed with locating hole, joint pin is connected into locating hole, its special feature is: be distributed with guiding groove 3 on described outlet frame 2 locating holes, joint pin is provided with positive stop lug boss 4, and positive stop lug boss 4 embeds in the guiding groove 3.
With regard to the utility model one preferred implementation, described guiding groove 3 is circular-arc, and positive stop lug boss 4 is provided with block tongue 5.The last end in contact of pendulum fan blade 1 block tongue 5 and circular-arc guiding groove 3 when be bottom state, the following end in contact of block tongue 5 and circular-arc guiding groove 3 when putting fan blade 1 and be last pendulum state is promptly as Fig. 2, shown in Figure 3.Simultaneously, consider the Fast Installation of positive stop lug boss 4, joint pin is that " protruding " word shape connects plush copper 6, is provided with installing hole 7 in the positive stop lug boss 4, connects plush copper 6 and embeds in the installing hole 7.
In conjunction with actual operating position of the present utility model: on the joint pin of the step motor shaft in the air-conditioning and pendulum fan blade 1, be attached thereto together.During work, the pulse command that send according to automatically controlled plate stepper motor energising back drives pendulum fan blade 1 and swings up and down.Promptly when pendulum fan blade 1 was bottom state, the block tongue 5 on the positive stop lug boss 4 and the last end in contact of circular-arc guiding groove 3 guaranteed to put fan blade 1 for correct bottom state; When putting on beginning under the driving of pendulum fan blade 1 at stepper motor, the block tongue 5 final meetings on the positive stop lug boss 4 and the following end in contact of circular-arc guiding groove 3 limit the opening angle of putting fan blade 1.Thus, swing up and down the accurate control of angle, need not to allow the stepping motor that the opening angle of pendulum fan blade 1 is controlled by having realized positive stop lug boss 4 and cooperating of guiding groove 3 pendulum fan blade 1.
By above-mentioned character express also in conjunction with the accompanying drawings as can be seen, behind employing the utility model, need not to use high-precision stepper motor can realize pendulum fan blade 1 is swung up and down the control of precision, only get final product with cooperating of guiding groove 3 by positive stop lug boss 4.Simultaneously, can not increase extra manufacturing expense after adopting this structure, be fit to promote the use of in the art.
Certainly, more than only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
