Description

Technical Field

[0001] This invention relates to the technical field of sewing equipment, and particularly to a rotary hook structure. Background Technology

[0002] The rotary hook is an essential component in woven sewing. Its function is to hook the top thread on the needle and interweave it with the thread inside the bobbin to form a stitch. However, existing rotary hooks tend to curl during sewing due to the self-rotation of the thread, resulting in an unsatisfactory stitch and affecting the overall quality of the garment. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a rotary shuttle structure that effectively prevents thread curling, ensures the quality of the stitches, and improves the sewing quality of garments.

[0004] The technical solution is as follows: a rotary shuttle structure, comprising a rotary shuttle body, a mounting base on the rotary shuttle body, a mounting hole on the mounting base, a rotary shuttle bowl inside the rotary shuttle body, a retaining ring on the rotary shuttle body, a first tail hook on the retaining ring, a retaining ring edge strip that mates with the rotary shuttle bowl, a rotary shuttle skin on the rotary shuttle body corresponding to the retaining ring, and a second tail hook on the rotary shuttle body corresponding to the first tail hook.

[0005] A further feature is that the second tail hook is an elastic element; the second tail hook is adjustable; a guide groove is provided on the rotary hook body, and a fastening nut is provided on the guide groove, the second tail hook is connected to the fastening nut; a threaded sleeve is provided on the rotary hook body, and a thread that mates with the threaded sleeve is provided at the end of the second tail hook, the second tail hook being connected to the threaded sleeve through the thread.

[0006] The present invention adopts the above-mentioned solution. Since the rotary hook body is provided with a second tail hook corresponding to the first tail hook, during the sewing process, the second tail hook works with the first tail hook to tighten the thread, realizing two-time thread tension. This effectively prevents the thread from curling, ensures the quality of the sewing stitches, and improves the sewing quality of the garment. Attached Figure Description

[0007] Figure 1 This is a schematic diagram of a first embodiment of the rotary shuttle structure of the present invention; Figure 2 This is a schematic diagram of a second embodiment of the rotary shuttle structure of the present invention. Detailed Implementation

[0008] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0009] Example 1: See Figure 1A rotary shuttle structure includes a rotary shuttle body 1, a mounting base 2 on the rotary shuttle body 1, a mounting hole 3 on the mounting base 2, a rotary shuttle bowl 4 inside the rotary shuttle body 1, a retaining ring 5 on the rotary shuttle body 1, a retaining ring edge strip 6 that mates with the rotary shuttle bowl 4 to position the rotary shuttle bowl, a first tail hook 11 on the retaining ring 1, a rotary shuttle skin 7 on the rotary shuttle body 1 corresponding to the retaining ring 5, and a second tail hook 8 on the rotary shuttle body 1 corresponding to the first tail hook 11. During the sewing process, the second tail hook assists the first tail hook in tightening the thread, which effectively prevents the thread from curling, ensures the quality of the stitches, and improves the sewing quality of the garment.

[0010] The second tail hook 8 is adjustable. The rotary hook body 1 is provided with a guide groove 9, and a fastening nut 10 is provided on the guide groove 9. The second tail hook 8 is connected to the fastening nut 10. The length of the second tail hook can be adjusted by adjusting the fastening nut, so that the second tail hook can be used for different fabrics and threads, improving the adaptability of the rotary hook and more effectively improving the sewing quality of the garment.

[0011] Example 2: Figure 2 The rotary hook body 1 is provided with a screw sleeve 11, and the end of the second tail hook 8 is provided with a thread that mates with the screw sleeve (not shown in the figure). The second tail hook 8 is connected to the screw sleeve 12 through the thread to realize the front and back adjustment of the second tail hook. It is locked by the locking nut 13, so that the second tail hook can be used for different fabrics and sewing threads, improving the adaptability of the rotary hook and more effectively improving the sewing quality of clothing.

[0012] In the two embodiments described above, the second tail hook is preferably an elastic element, such as steel wire or other materials with a certain degree of elasticity, which ensures the elasticity to adapt to the sewing thread, further ensuring the aesthetics of the sewing stitches and effectively improving the sewing quality of the garment.

[0013] The two embodiments described above only describe two adjustment methods for the second tail hook. Of course, other adjustment methods can also be used. As long as it can be adjusted back and forth for different fabrics and different stitching, it is within the scope of protection of this invention.

[0014] The present invention and its embodiments have been described above illustratively. This description is not restrictive. The figures shown are only one embodiment of the present invention. The actual structure is not limited to this. Those skilled in the art, inspired by this description, may design similar structures and embodiments without departing from the spirit of the invention. Such designs should fall within the protection scope of the present invention.
