At present, the fan blade of blower fan mostly is thermoplastic and metal, and use thermoplasticity fan blade to be easily out of shape, affect using effect, use metallic material, fan blade weight, processing difficulties inconvenience is shaping.Because current fan blade outlet air surface is smooth surface, noise is larger, wind-force is concentrated not, fan blade angle is non-adjustable, its inclination angle is changeless, can not according to work on the spot demand wind-force size adjustment fan blade inclination angle, thus cause enterprise and need to buy the demand that the product of different size carrys out satisfied different wind-force, increase the weight of the cost of enterprise.In prior art, the angle that the angle adjustment assembly of fan blade can regulate is less, causes people cannot adjust satisfied fan blade angle, thus needs the fan blade purchasing different size.
Such as, Chinese patent literature discloses a kind of adjustable fan blade [application number: 201120336065.5], comprise blade, metal reinforcing plates is provided with in the blade that glass fiber reinforced plastics composite material is made, cylindric fixing handle is arranged in one end of blade, cylindric fixing is provided with boss afterbody, cylindric fixing, side is provided with blade tilt scale.
Although improve prior art to a certain extent in such scheme, can regulate fan blade angle, still also exist and can design not rationally, can regulate the limited angle of fan blade, validity is high-technology problem not.
Summary of the invention
The purpose of this utility model is for the problems referred to above, and provide a kind of reasonable in design, structure is simple, the angle adjustment assembly of the fan blade multi-angle accurate adjusting mechanism that angle of regulation range is wide.
For achieving the above object, the utility model have employed following technical proposal: the angle adjustment assembly of this fan blade multi-angle accurate adjusting mechanism, it is characterized in that, this assembly comprises connecting head, adjustment setting sleeve is had in connecting head outer race, the external groove of some covers along regulating the distribution of setting sleeve circumference is provided with outside described adjustment setting sleeve, some external tooths along the distribution of connecting head circumference are provided with outside described connecting head, some internal tooths along regulating the distribution of setting sleeve circumference are provided with inside described adjustment setting sleeve, described external tooth and each external tooth and each internal tooth equal with the quantity of internal tooth all can be worked in coordination.
In the angle adjustment assembly of above-mentioned fan blade multi-angle accurate adjusting mechanism, be provided with 36 external tooths along the distribution of connecting head circumference outside described connecting head, be provided with 36 inside described adjustment setting sleeve along the internal tooth regulating the distribution of setting sleeve circumference.
In the angle adjustment assembly of above-mentioned fan blade multi-angle accurate adjusting mechanism, taper type large in little rear end, front end outside described adjustment setting sleeve.
In the angle adjustment assembly of above-mentioned fan blade multi-angle accurate adjusting mechanism, the inner side of described adjustment setting sleeve is the large taper type in little rear end, front end, and described connecting head is the large taper type in little rear end, front end.
In the angle adjustment assembly of above-mentioned fan blade multi-angle accurate adjusting mechanism, the external groove of described cover is divided into equally distributed some groups and each group to comprise some intervals respectively and overlap external groove uniformly.
In the angle adjustment assembly of above-mentioned fan blade multi-angle accurate adjusting mechanism, the external groove of described cover is divided into two groups, often organizes and comprises uniform five the external grooves of cover in interval respectively, different along adjustment setting sleeve circumference spacing between two groups.
Compared with prior art, the advantage of the angle adjustment assembly of this fan blade multi-angle accurate adjusting mechanism is: 1, reasonable in design, and structure is simple, and angle of regulation range is wide.2, sound construction, intensity are high, ensure that fan blade can not be excessive and cause blade to change angle because eating wind-force in rotation process.3, degrees of freedom is high, can regulate fan blade fast, and wind-force can meet the demand of people.
Accompanying drawing explanation
