Abstract
The utility model provides a hand wheel on a sewing machine, and belongs to the technical field of sewing machines. The technical problem that when a hand wheel is rotated, slipping easily occurs in the prior art is solved. The sewing machine comprises a motor and a motor shaft arranged in the motor. The hand wheel comprises a cylindrical wheel body, a connecting base used for being connected with the motor shaft is arranged in the wheel body, and a plurality of wave-shaped protrusions are further arranged on the inner side wall of the wheel body. The hand wheel is not prone to slipping in use, and good in operation convenience.
Description
Technical field
The utility model belongs to the sewing machine technique field, relates to the handwheel on a kind of Sewing machines.
Background technology
Existing Sewing machines is equipped with the drive units such as motor usually in sewing machine case, move up and down by the shank at a series of drive disk assembly drive head position and the eedle of shank lower end, and in order to regulate the upper-lower position of eedle, usually the motor shaft in the motor back arranges handwheel, thereby the manual rotation handwheel drives upper axle rotation and then regulates the eedle height, manually sews.
China patent CN201713664U discloses a kind of Anti-enwind handwheel of direct-drive high-speed sewing machine, and this handwheel comprises the handwheel main body, and handwheel main center is shaped with axis hole, is shaped with wheel rim at the periphery of handwheel main body, it is characterized in that being shaped with on the described wheel rim poly-wire casing.This programme is owing to being shaped with poly-wire casing at wheel rim, during work, the suture that is wound on the head at first can be around in poly-wire casing, blocked the inside that suture enters motor, and suture can be more poly-more, add the large cause of the resistance of suture own, cause suture gradually to external diffusion, prevent that suture from because entering motor internal the purpose that motor damages occuring, and utilizes safety operation thereby arrive.
But the interior outside of above-mentioned handwheel is all more smooth, and the user is easily skidded when gripping the rotation handwheel, neither is convenient to user's normal operating, has reduced again the rotation precision of handwheel, thereby has affected stitching sewing machine fabric quality out.
Summary of the invention
The utility model is the problems referred to above that exist for existing technology, and the handwheel on a kind of Sewing machines is provided, and technical problem to be solved in the utility model is: how skid when avoiding the user to rotate handwheel, improve the simple operation of this handwheel.
Handwheel on a kind of Sewing machines, Sewing machines comprises motor and is arranged at the interior motor shaft of this motor, it is characterized in that, this handwheel comprises a wheel body cylindraceous, be provided with the Connection Block that links to each other for described motor shaft in this wheel body, also have several wavy projections on the madial wall of this wheel body.
Be designed with wavy projection on this sewing machine hand-wheel, the user when rotating handwheel, the phenomenon that can not skid, thereby the simple operation that improves this handwheel; And be wavy with convex design, can be when guaranteeing the handwheel overall aesthetics, when can avoiding the user to grip wheel body, its curved surfaces pressed against wound, and it is wavy that projection is, adjacent two projections then can form a depressed part, this depressed part just can match with user's finger, further improves the simple operation of this handwheel.
In the handwheel on above-mentioned a kind of Sewing machines, described wheel body and projection adopt aluminium alloy or magnesium alloy to make, and this wheel body and protruding for adopting the integral structure of extrusion modling.Aluminium alloy density is little, and intensity is high and plasticity good, can be processed into various section bars, and has good corrosion resistance; And magnesium alloy proportion belongs to the lighter in all structures in alloy, can be when not reducing handwheel intensity, significantly alleviate the overall weight of handwheel, and the outward appearance of magnesium alloy and touch texture are splendid, can make handwheel integral body seem more luxurious, and aluminium alloy and magnesium alloy all can adopt extrusion modling, improve the production efficiency of handwheel.
In the handwheel on above-mentioned a kind of Sewing machines, as preferably, described wheel body and projection adopt 7075 aluminium alloys to make.
In the handwheel on above-mentioned a kind of Sewing machines, described several projections are distributed on the madial wall of described wheel body in the form of a ring.Projection is uniform in the form of a ring, when the user rotates handwheel, no matter forwards which angle to, all can grip the projection on the wheel body, avoids skidding.
In the handwheel on above-mentioned a kind of Sewing machines, described Connection Block is fixed in the center of described wheel body, and this Connection Block comprises a body in the form of a ring, offers a central through hole that can be sheathed on the described motor shaft on this body.After being designed with central through hole on the Connection Block, make things convenient for the suit of handwheel and motor shaft, improve efficiency of assembling.
Compared with prior art, the utlity model has following advantage:
1, be designed with wavy projection on this sewing machine hand-wheel, the user is when rotating handwheel, and the phenomenon that can not skid makes the simple operation of this handwheel higher;
2, wheel body and projection adopt aluminium alloy or magnesium alloy to make, and can when not reducing handwheel intensity, significantly alleviate the overall weight of handwheel, and production efficiency be higher.
Description of drawings
Fig. 1 is the structural representation of this handwheel among the embodiment.
Among the figure, 1, wheel body; 2, Connection Block; 3, body; 4, central through hole; 5, projection; 6, opening.
The specific embodiment
Below be specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, this Sewing machines comprises motor and is arranged at the interior motor shaft of this motor, this handwheel comprises a wheel body 1 cylindraceous, be provided with in this wheel body 1 for the Connection Block 2 that links to each other with motor shaft, Connection Block 2 in the present embodiment is fixed in the center of wheel body 1, this Connection Block 2 comprises a body 3 in the form of a ring, offers a central through hole 4 that can be sheathed on the motor shaft on this body 3.
As shown in Figure 1, be evenly equipped with in the form of a ring on the madial wall of wheel body 1 that several are wavy protruding 5, wheel body 1 and projection 5 adopt aluminium alloys or magnesium alloy to make, and this wheel body 1 and projection 5 are for adopting the integral structures of extrusion modling.Wheel body 1 in the present embodiment and projection 5 preferred 7075 aluminium alloys that adopt are made.
As shown in Figure 1, offer two via holes one on the sidewall of body 3, offer on the sidewall of wheel body 1 two with via hole one via hole two one to one, via hole one and via hole two interior simultaneously be equipped with bolts corresponding with this via hole one.Also offer a sagittate opening 6 on the wheel body 1, be used to indicate the positive veer of handwheel.
