Description
Technical Field
The utility model relates to the technical field of fan blades, in particular to an angle-adjustable axial flow fan blade.
Background
An axial flow fan is commonly adopted on an external machine of the air conditioner and is used for taking away heat on a condenser so as to realize indoor and outdoor heat exchange effects.
However, in air conditioners with different specifications, the required heat dissipation capacity is different, and the fan blade inclination angle of the axial flow fan is generally fixed, so that the heat dissipation performance of various different requirements cannot be considered, and the problem that one-time mold opening is required for products with different batches is caused, so that the production cost is greatly increased.
Disclosure of utility model
The utility model aims to provide an axial flow fan blade with an adjustable angle.
The technical aim of the utility model is realized by the following technical scheme: the axial flow fan blade with the adjustable angle comprises a cover body positioned in the middle, a plurality of perforations are formed in the cover body, a plurality of groups of transverse grooves with different inclination angles are formed in the inner wall of each perforation, an extension rod is arranged in each perforation in a penetrating mode, transverse sheets matched with the transverse grooves are arranged at the inner ends of the extension rods, and fan blades are arranged at the outer ends of the extension rods; a bottom plate is arranged in the cover body, and one side of the inner end of the extension rod is fixed on the bottom plate through a screw.
Further provided is that: the transverse grooves are grouped into groups of four.
Further provided is that: the bottom plate is provided with different inclination angles of the adaptation transverse piece, and the bottom plate is provided with an arc-shaped groove of the adaptation extension rod.
Further provided is that: the screws are arranged on the transverse pieces of the extension rod.
Further provided is that: the cover body comprises an upper cover and a lower cover, and the bottom plate and the perforations are all arranged on the lower cover.
Further provided is that: the cross section of the bottom plate is cross-shaped.
In summary, the utility model has the following beneficial effects: through the axial flow fan blade, when fan blades with different angles are needed, the minimum 2-degree change angle of the fan blades can be realized by changing the positions of the perforations where the extension rods are positioned, and the total change angle can be changed into 10-degree change of different angles. Therefore, when facing air conditioners with different specifications, the die-sinking mechanism can correspondingly adjust the small-batch products to be faced, so that the frequent die sinking is not needed, the production cost is greatly reduced, and the funds are saved.

In the figure: 1. a cover body; 11. an upper cover; 12. a lower cover; 2. perforating; 3. a transverse slot; 4. an extension rod; 5. a transverse sheet; 6. a fan blade; 7. a bottom plate; 8. a screw; 9. an arc-shaped groove.
Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings.
The axial flow fan blade with the adjustable angle comprises a cover body 1 positioned in the middle, wherein the cover body 1 comprises an upper cover 11 and a lower cover 12, and the upper cover 11 and the lower cover 12 are fixed through viscose or screws 8.
Wherein, be provided with a plurality of perforation 2 on the lateral wall of lower cover 12 body 1, still be provided with a plurality of bottom plates 7 that correspond perforation 2 on the lower cover 12 body 1, bottom plate 7 is the cross. The inner wall of the through hole 2 is provided with a plurality of groups of transverse grooves 3 with different angles, and the inclination angles of the transverse grooves 3 on different through holes 2 are different, and are preferably set as a group by rotating 2 degrees.
An extension rod 4 is arranged in the perforation 2 in a penetrating way, a transverse sheet 5 is arranged on the inner end side wall of the extension rod 4, the transverse sheet 5 is inserted inwards into the perforation 2, and the transverse sheet 5 is in abutting arrangement with the transverse groove 3. The outer end of the extension rod 4 is provided with a fan blade 6. Wherein the transverse grooves 3 are arranged in 5 groups in total, and the rotation angle is 10 degrees at most.
A plurality of bottom plates 7 are arranged on the lower cover 12 body 1, the bottom plates 7 are in one-to-one correspondence with the perforations 2, and arc-shaped grooves 9 which are matched with the extension rods 4 are arranged on the bottom plates 7. The inclination angles of the bottom plates 7 are also in one-to-one correspondence with the transverse grooves 3. The cross section of the bottom plate 7 is cross-shaped, and the transverse pieces 5 at the inner ends of the extension rods 4 are fixed on two sides of the cross shape of the bottom plate 7 through screws 8.
When the fan blades 6 with different angles are needed, the minimum 2-degree change angle of the fan blades 6 can be realized by changing the position of the through hole 2 where the extension rod 4 is positioned, and the total change angle can be changed to 10 degrees of different angles. Therefore, when facing air conditioners with different specifications, the die-sinking mechanism can correspondingly adjust the small-batch products to be faced, so that the frequent die sinking is not needed, the production cost is greatly reduced, and the funds are saved.
The present embodiment is only for explanation of the present utility model and is not to be construed as limiting the present utility model, and modifications to the present embodiment, which may not creatively contribute to the present utility model as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present utility model.
