The novel blade comprises a blade main body and a metal shaft sleeve, wherein the blade main body is composed of a base body and a plurality of blades uniformly distributed along the center of the base body, the metal shaft sleeve is used as a mounting hole position, the metal shaft sleeve is integrally injection molded in the base body of the blade main body, each blade is provided with a curved surface contour surface which is concave inwards on the front surface, and the blade main body can increase the contact surface with air through the curved surface contour surface in the rotating process so as to increase the wind sweeping area. The advantages are that: the installation accuracy can be directly improved, the heat dissipation is fast, and the service life is prolonged, and the heat dissipation structure is durable in use and resistant to high temperature. The integral strength of injection molding is improved, the blade is not easy to fall off even when meeting high temperature, the use reliability is guaranteed, and the contact surface between the blade body and air can be increased through the curved surface contour surface in the rotation process, so that the air sweeping area is increased, and the air quantity is increased.

Description

Integrated motor fan blade

Technical Field

The utility model relates to a motor fan blade, specific integrated into one piece formula motor fan blade that says so.

Background

As a fan product generally used in daily life, a fan for providing power is generally used as a standard for performance evaluation, and the blade serving as an air supply unit is ignored to have the same important function.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a blade angle reasonable in design, the air supply volume is big, the wearability is good, intensity is high to can improve the integrated into one piece formula motor fan blade of stability in use and increase of service life.

In order to solve the technical problem, the utility model discloses an integrated into one piece formula motor fan blade, include the blade main part that comprises the base member and the multi-disc flabellum of evenly arranging along the base member center, still include the metal axle sleeve as the installation hole site, the integrative injection moulding of metal axle sleeve is in the base member of blade main part, and each flabellum all has the curved surface profile surface of indent on the front surface, and the blade main part can pass through at rotatory in-process thereby curved surface profile surface increases the area of sweeping the wind with the contact surface increase of air.

The blade main body at least comprises three fan blades which are integrally formed on the base body.

And reinforcing ribs are distributed on the outer circumferential surface of the metal shaft sleeve.

The reinforcing rib is of a T-shaped structure.

The outer surface of the metal shaft sleeve is provided with a pattern surface.

The rear part of the base body is provided with an annular sleeve positioned at the periphery of the metal shaft sleeve, and rib plates arranged in a radial mode are arranged between the metal shaft sleeve and the annular sleeve.

Screw holes are arranged on the annular sleeve.

The utility model has the advantages of:

(1) Through with the integrative injection moulding of metal axle sleeve in the blade main part, not only can directly utilize the metal axle sleeve to improve the installation accuracy but also can directly utilize the high temperature resistance and the thermal diffusivity of metal axle sleeve from this, make it also more durable in the use, high temperature resistant, the heat dissipation is fast, has prolonged life.

(2) Still through the strengthening rib of having arranged and set up the decorative pattern surface at the surface of metal axle sleeve, improved injection moulding's bulk strength from this, even if meet high temperature also be difficult for droing, guaranteed the reliability of using, further prolonged life.

(3) The concave curved surface contour surface is designed on the front surface of each fan blade, so that the contact surface between the fan blade main body and air can be increased through the curved surface contour surface in the rotation process of the fan blade main body, the wind sweeping area is increased, and the wind quantity is increased.

(4) The annular sleeve is provided with the screw holes, so that the movable balance sleeve can be locked according to the dynamic balance requirement, convenient and fast installation in different places is facilitated, and the condition of screw thread sliding is avoided.

(5) Ribs arranged radially are arranged between the metal shaft sleeve and the annular sleeve, so that the strength of a stressed part is improved, and the service life is further prolonged.

Detailed Description

The following describes the integrally formed motor blade in detail with reference to the accompanying drawings and the detailed description.

As shown in the figure, the utility model discloses an integrated into one piece formula motor fan blade, include by base member 1 and the blade main part 3 that 4-6 flabellum 2 evenly arrange along the base member center constitute, wherein the quantity of blade is preferred four, still include the metal axle sleeve 4 as the installation hole site, 4 integrative injection moulding of metal axle sleeve is in the base member 1 of blade main part, specifically speaking, metal axle sleeve 4 is embedded into in blade main part 3 at the injection moulding in-process, each flabellum 2 all has the curved surface profile surface of indent on the front surface, thereby blade main part 3 can increase the area of sweeping the wind through the contact surface increase of curved surface profile surface with the air in rotatory process, it produces the power of turning to keep wind more easily, the amount of wind has been increased from this.

Furthermore, the T-shaped reinforcing ribs 5 are arranged on the outer circumferential surface of the metal shaft sleeve 4, and the outer surface of the metal shaft sleeve 4 can be provided with a pattern surface, so that the bonding strength in the injection molding process is increased through the arranged T-shaped reinforcing ribs 5 and the arranged pattern surface, and the overall strength of the product is improved.

The rear portion of base member 1 is provided with and is located the peripheral annular cover 6 of metal axle sleeve, has the gusset 7 that is radial arrangement between metal axle sleeve 4 and the annular cover 6, and the screw hole 8 that arranges on the annular cover 6 can a plurality of positions installation screw through the screw hole of arranging, is favorable to improving dynamic balance's effect, realizes the silence operation.
