Abstract
The utility model provides a fan hand wheel with an air suction function, belongs to the technical field of sewing machines, and solves the problem that the existing fan hand wheel has poor cooling effect and large noise. The fan hand wheel with the air suction function provided by the utility model comprises a hand wheel disc, wherein a plurality of ventilation holes are uniformly distributed on the hand wheel disc along the circumferential direction; a wheel sleeve is formed on the periphery of an outer circle of the hand wheel disc; and a plurality of blades which are radially arranged and capable of sucking air in a motor are uniformly distributed on the side surface, facing the motor, of the hand wheel disc. The fan hand wheel provided by the utility model has the advantages of simple structure, good practical effect and the like.
Description
Technical field
The utility model belongs to the sewing machine technique field, particularly has the fan handwheel of air suction function.
Background technology
Sewing machine hand-wheel is the important component part of Sewing machines, can carry out the adjusting of Sewing needles by handwheel.
At present, usually sewing machine hand-wheel has been not limited to single eedle regulatory function, can be used as a kind of heat abstractor at handwheel installing flabellum, but existing handwheel with fan functionality is the blowing handwheel, the air that is about in the sewing machine body is extracted out, and this structure is relatively poor to the cooling-down effect of motor, and noise is large.
Summary of the invention
That the purpose of this utility model provides is simple in structure, cooling-down effect is good, widely used fan handwheel with air suction function.
The purpose of this utility model is achieved in that the fan handwheel with air suction function, comprise the handwheel wheel disc that circumferentially is evenly equipped with some air vents, form wheel case on the circumferential periphery of wheel disc, it is characterized in that: described wheel disc sucks wind to the flabellum of motor towards circumferentially being evenly equipped be that radioactivity arranges some on the side of motor can be in the wheel disc spins time.
Operation principle of the present utility model is: this handwheel is to be located on the machine shaft of Sewing machines one end, pass through motor-driven, but at the flabellum that is provided with air draught towards the side of motor, when motor is in running order, but air draught to motor is lowered the temperature to motor, the wind that sucks simultaneously will flow out from the opening of Sewing machines one side, the inner wind chamber that forms of Sewing machines, and therefore the effect of cooling is splendid.
In the above-mentioned fan handwheel with air suction function, described flabellum is counterclockwise or clockwise crooked prismatoid, and a side of prismatoid is molded on the madial wall of wheel case.
In the above-mentioned fan handwheel with air suction function, described air vent is the air vent of nine arcs, and described nine air vents are that two the little air vents in every interval arrange a large air vent.
In the above-mentioned fan handwheel with air suction function, described flabellum is arranged on the outside of adjacent two little air vents and large air vent.
The utility model compared to existing technology outstanding and useful technique effect is:
1, the utility model can be with in the air intake sewing machine body, and air-flow flows out by the opening on the sewing machine body again, forms circulation, and internal body forms the wind chamber, so cooling-down effect is good.
2, the utility model according to the difference that turns to of different sewing machines, only needs to adopt blade structure clockwise or that counter clockwise direction is crooked to get final product applicable on the multiple Sewing machines.
3, of the present utility model simple in structure, practical function is good.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structural representation of the present utility model.
The specific embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-2:
Fan handwheel with air suction function, comprise the handwheel wheel disc 1 that circumferentially is evenly equipped with some air vents, form wheel case 3 on the circumferential periphery of wheel disc 1, it is characterized in that: described wheel disc 1 sucks wind to the flabellum 4 of motor towards circumferentially being evenly equipped be that radioactivity arranges some on the side of motor can be in the wheel disc spins time.Operation principle of the present utility model is: this handwheel is to be located on the machine shaft of Sewing machines one end, pass through motor-driven, but at the flabellum that is provided with air draught 4 towards the side of motor, when motor is in running order, but air draught to motor is lowered the temperature to motor, the wind that sucks simultaneously will flow out from the opening of Sewing machines one side, the inner wind chamber that forms of Sewing machines, and therefore the effect of cooling is splendid.
Be counterclockwise or clockwise crooked prismatoid at above-mentioned flabellum 4, a side of prismatoid is molded on the madial wall of wheel case.This handwheel can apply on the dissimilar Sewing machiness, and routine flat seam machine, overlock machine because of the motor steering difference of different sewing machines, so only need to adopt counterclockwise or clockwise crooked different flabellums 4 to finish the work.
Be the air vent of nine arcs at above-mentioned air vent, described nine air vents are that two the little air vents 22 in every interval arrange a large air vent 21.
Be arranged on the outside of adjacent two little air vents 22 and large air vent 21 at above-mentioned flabellum 4.
Above-described embodiment is preferred embodiment of the present utility model only, is not to limit according to this protection domain of the present utility model, so: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.
