Fig. 3 is the dimensional structure diagram for the another plastics peg or spindle that the utility model embodiment provides；
Wherein：1- rolls, 2- flanges, 21- outer edges, 22- inward flanges, 3- curved surfaces, 4- axis holes, 5- inclined grooves, 6-
Inclined surface.
Specific implementation mode
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining this practicality
It is novel, it is not intended to limit the scope of the utility model.
The utility model embodiment provides a kind of plastics peg or spindle, referring to Fig.1 shown in -2, including：It roll 1 and sets respectively
It sets at 1 both ends of roll and radially outward extends flange 2；Roll 1 is in drum-shaped, and the both ends of roll are along its axis
It is equipped with axis hole to direction；One of them is known as the first flange for two flanges 2, another is known as the second flange；Above-mentioned two flange 2
One side far from roll 1 is in circular ring shape；Above-mentioned roll, the first flange and the second flange are that engineering plastics are made, and
Integrated molding, roll 1 and flange 2 are I-shaped along the section of 1 axis direction of roll.
In the present embodiment, which is made of engineering plastics, and rigidity is big, and creep is small, high mechanical strength, heat resistance
Good, electrical insulating property is good, and on the basis of maintaining opposite hardness, compared to the metals peg or spindles such as iron and aluminum, lighter in weight；
Sewing machine using the utility model embodiment provide plastics peg or spindle when, have better braking effect and more stabilization
Stitching；Compared to conventional metals shuttle braking core, hardness is moderate, can effectively reduce broken needle probability.
And bobbin case is metal material, when peg or spindle uses engineering plastics, frictional force when being used cooperatively between bobbin case
Smaller, the friction that can be efficiently solved between metal bobbin case and metal peg or spindle is big, leads to the problem that parts depreciation is serious；And
And when peg or spindle is in the case of baseline surplus very little, stable tension still can be kept to export.
Further, engineering plastics can be divided into two class of general engineering plastic and special engineering plastics again.The present embodiment provides
Plastics peg or spindle, can be used special engineering plastics, for example acetal resin (Polyoxymethylene can be selected
(Polyformaldehyde), POM) plastics, polyimides, polyphenylene sulfide, polysulfones, aromatic polyamide, polyarylate, polyphenyl
Any one in ester, poly(aryl ether ketone), liquid crystal polymer or fluororesin, the utility model discloses embodiment and does not limit this
It is fixed.
The plastics peg or spindle can bear certain frictional force in use, it is necessary to have higher intensity and just
Property, while should also have good wearability and heat resistance.
POM plastic can be selected in above-mentioned engineering plastics, for example can select enhancing POM, and main reinforcing material is glass fibers
Dimension, glass marble or carbon fiber etc., enhanced POM plastic mechanical property can be improved 2~3 times, heat distortion temperature improve 50 DEG C with
On, and corrosion-resistant and high-temperature resistant.
Polyimides also can be selected, have higher intensity and impact resistance, excellent dimensional stability good heat-resisting
Property and fatigue durability.
Above-mentioned engineering plastics are the ideal materials for manufacturing plastics peg or spindle, they not only have enough intensity, rigid and resistance to
It is hot, and friction factor is low, for example can be operated under conditions of unlubricated, relative density is small, can mitigate the weight of transmission parts
Amount, also reduces starting inertia.
In addition, can be different according to the specifically used type in the process of plastics bobbin case, above-mentioned unlike material may be selected, manufactured
For multiple colors such as the bluish-green black and white of reddish yellow, transparent plastic peg or spindle can also be manufactured it as, as the engineering plastics of transparent material,
Mainly there are such as makrolon, transparent ABS, AS, PS, PMMA etc..It in the specific implementation, can be according to different demands in different colours
The line of different size, management easy to produce are used on peg or spindle.
Further, shown in referring to Fig.1, the edge of two flanges 2 is begun to transition into an axial direction from intermediate roll 1
Place, for the circular arc being recessed inwardly, i.e.,：The curved surface seamlessly transitted is formed between roll and two flanges one side close to each other
3, it acts as outlet can be made to become more smooth during using peg or spindle.
Further, with reference to shown in Fig. 3, the both ends of roll are being equipped with axis hole 4 along its axial direction, when peg or spindle is in bobbin case
It is interior with the use of when, in order to increase the stability of peg or spindle, on the inner wall of two axis holes 4 with and the position of corresponding flange 2 open up
There are at least one inclined groove 5, the slot bottom of inclined groove 5 tilted to axis hole 4；And the quantity of tilted upward groove 5 needs to protect
It holds identical, answers along roll 1 is axially opposing.
For example the quantity of tilted upward groove 5 is set as seven, between every group of seven inclined grooves 5 equidistantly, and first
The inclined groove 5 of flange side and about 5 inclined groove of the second flange side in correspondence with each other, are combined with overall construction, are loaded
Seven inclined grooves 5 coordinate overall construction after in bobbin case, and peg or spindle can be made more firm, can be protected during sewing or embroidery
Demonstrate,prove the fluency of knit stitch and outlet.
Further, referring to Fig.1, shown in 2, the one side of the first flange and the second flange far from roll 1 be tilt
Face 6 is inclined outwardly by the outer edge 21 of flange 2 and extends to the inward flange 22 of flange 2 and formed, and the angle of inclination a of the inclined surface 6 is
1~5 °.When the case where encountering inclined surface 6 of the stylus printer to bobbin flanges 2 during sewing or embroidering, due to there is inclination angle
Degree, can be such that needle deflects away from, and needle does not allow frangibility, and because peg or spindle is special engineering plastics, will not stab peg or spindle.
Further, the outer edge 21 of one side of the flange 2 far from roll 1 is set to arc transition, it is possible to reduce
Friction between bobbin case, and outlet is further made to become more smooth.
In use, in order to make coiling become to be more prone to, raised line can be equipped in the peripheral surface of roll 1
Road, for example the shape of lines can be the polygons such as diamond shape, rectangle and the triangle of rule, can also be round or irregular
Shape.
Conceived based on same utility model, the utility model embodiment also provides a kind of sewing machine shuttle peg external member, due to this
The principle of the solved problem of sewing machine shuttle peg external member is similar to foregoing plastics peg or spindle, therefore the implementation of the sewing machine shuttle peg external member can
With referring to the implementation of foregoing plastics peg or spindle, overlaps will not be repeated.
The utility model embodiment also provides a kind of sewing machine shuttle peg external member, including bobbin case and such as any of the above-described embodiment
The plastics peg or spindle provided, friction is small when being used cooperatively between the plastics peg or spindle and bobbin case, can efficiently solve metal
Friction between bobbin case and metal peg or spindle is big, leads to the problem that parts depreciation is serious；Also, when peg or spindle is in baseline surplus very little
In the case of, stable tension still can be kept to export.
Obviously, those skilled in the art can carry out the utility model various modification and variations without departing from this practicality
Novel spirit and scope.If in this way, these modifications and variations of the present invention belong to the utility model claims and
Within the scope of its equivalent technologies, then the utility model is also intended to include these modifications and variations.
