[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0018] like Figures 1-4 As shown, an anti-loosening knitting needle structure for a computerized flat knitting machine includes a main shaft 1 and a needle body 8. A connecting ring 3 is sleeved on the outer wall of the main shaft 1. A first positioning bolt 5 is threadedly connected to one side of the connecting ring 3, and a second positioning bolt 7 is threadedly connected to the other side of the connecting ring 3. A needle hook 9 is installed on the top of the needle body 8, and an anti-loosening component 10 is movably connected to the bottom of the needle hook 9. A through groove 6 is opened in the center of the main shaft 1, and adjusting grooves 2 are symmetrically opened at both ends of the main shaft 1. The adjusting grooves 2 communicate with the inner cavity of the through groove 6. A connecting frame 4 is installed in the center of the inner cavity of the connecting ring 3. The connecting frame 4 is movably connected in the inner cavity of the adjusting groove 2 and the through groove 6. The opposite sides of the first positioning bolt 5 and the second positioning bolt 7 are symmetrically attached to the two sides of the outer wall of the main shaft 1. The bottom of the knitting needle body 8 is movably connected to the inner cavity of the main shaft 1 through the through groove 6. The bottom of the knitting needle body 8 is installed on the top of the connecting frame 4. The anti-loosening component 10 is movably connected to the inner cavity of the bottom of the needle hook 9. The bottom of the anti-loosening component 10 has a contact surface 11, which is an inclined surface. The top of the anti-loosening component 10 is equipped with a limiting block 15. Movable blocks 13 are symmetrically installed around the outer wall of the limiting block 15. A spring 12 is installed on the top of the limiting block 15. The limiting block 15 is movably connected to the inner cavity of the needle hook 9. The top of the spring 12 is installed in the inner cavity of the needle hook 9. Guide rods 14 are symmetrically installed around the bottom of the inner cavity of the needle hook 9. Movable blocks 13 are movably connected to the inner cavity of the needle hook 9 and sleeved on the outer wall of the guide rods 14. The anti-loosening component 10, under normal conditions, can adhere to the outer wall of the needle body 8. Therefore, during knitting, it seals the gap between the needle body 8 and the needle hook 9, preventing the shedding of fine yarns or elastic yarns. This reduces defects caused by yarn breakage and needle tipping, making it more suitable for knitting delicate fabrics such as lace dresses. The adjusting groove 2 and through groove 6 allow the connecting ring 3 and connecting frame 4 to move the needle body 8 up and down within the main shaft 1.
