Description

The shuttle device of a kind of suture needle car

[technical field]

The utility model relates to the shuttle device of a kind of suture needle car, particularly a kind of shuttle device that does not have this suture needle car of shuttle.

[background technology]

This suture needle car is an indispensable tailor in our daily life, is widely used in clothing, shoemaking, hatting, system bag, system umbrella, system curtain etc.The shuttle device of traditional this suture needle car mainly comprises bobbin case and places shuttle among the bobbin case, and then bobbin case is installed in the big still, and the lower end of big still connects the still axle, forms whole shuttle device.During use, need earlier the sewing machine line to be wrapped in shuttle, after the through wires hole from the shuttle passes again, pass bobbin case again.The shuttle device of this structure, be for line by shuttle, yet the sewing machine line that shuttle twined is very limited, will often change shuttle in the use, not only waste a large amount of working time, and shuttle cost height has improved the cost of product virtually, use has this suture needle car of the shuttle device of shuttle, because the sewing machine line that shuttle twined is very limited, so the product the end of a thread that causes lifelong tenure to come out is many, has influenced the quality of product.

[utility model content]

The purpose of this utility model is to solve the deficiencies in the prior art, provides a kind of and both can save time, save cost, a kind of shuttle device that does not have this suture needle car of shuttle that improves the quality of products again.

The utility model is achieved by the following technical programs: the shuttle device of a kind of suture needle car, comprise still axle, big still, bobbin case, described bobbin case is located in the big still, the center of described still axle is provided with axial through bore, and the upper end of still axle is connected with described big still with a screw that is provided with axial through bore.

Be compared to previous technology, the utlity model has following advantage:

1, adopts the shuttle device of no shuttle, saved the working time of changing shuttle, saved the cost of a large amount of shuttles, reduced the cost of product;

2, adopt the shuttle device of no shuttle, use not limit for length's sewing machine line in use instead, produced product seldom has the end of a thread, has improved product quality.

[description of drawings]

In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.

Fig. 1 is each exploded sketch of shuttle device of the present utility model.

[specific embodiment]

Seeing also shown in Figure 1ly, is each exploded sketch of the present utility model, discloses the structure of this shuttle device among the figure, mainly comprises still axle 1, big still 2, bobbin case 3 and screw 4.The center of described still axle 1 is axially arranged with perforation 11, and an end of the perforation 11 of still axle 1 and the inner ring of big still 2 are provided with and the corresponding internal thread of described screw 4 external screw threads, and by screw 4 with still axle 1 and greatly still 2 the two axially screw and be connected.Described bobbin case 3 is located at the inside of big still 2, and bobbin case 3 is provided with a through wires hole 31; Described screw 4 centers also are provided with perforation 41.During assembling the perforation 11 of still axle 1 and the inner ring of big still 2 are aimed at, again screw 4 is passed behind the inner ring of big still 2 again perforation 11 with still axle 1 and screw and get final product.

During use, sewing machine line 5 is passed the perforation 11 of still axle 1, and then pass the perforation 41 of screw 4, through wires hole 31 outlets from the bobbin case 3 can be used at last.The shuttle device of this structure no longer supplies line by shuttle, and limit for length's sewing machine line supplies line but use instead not, not only improves operating efficiency, saves cost, has also promoted the quality of quilt.

Claims

1, the shuttle device of a kind of suture needle car comprises still axle, big still, bobbin case, and described bobbin case is located in the big still, it is characterized in that: the center of described still axle is provided with axial through bore, and the upper end of still axle is connected with described big still with a screw that is provided with axial through bore.
