Description

Technical Field

[0001] The utility model belongs to a knitting component, in particular to a knitting needle used for knitting. Background Art

[0002] The weaving components of a flat knitting machine include a front needle plate and a rear needle plate symmetrically arranged in a herringbone shape. The front and rear needle plates are respectively provided with corresponding needle grooves. Each needle groove is formed by two inserts inserted into the needle plate to form the side walls of the needle groove, and a knitting needle is embedded in the needle groove. Existing knitting needles include a needle hook, a needle tongue, a needle handle, and a spring leaf. The needle handle includes a needle bar, a needle body, and a needle tail connected as a whole from front to back. The needle hook is integrally connected to the front end of the needle bar, and the needle tongue is hinged to the rear end of the needle hook. The needle hook is opened and closed by rotation. The needle body is wider than the needle bar, and a step-shaped first transfer portion is formed at the connection between the needle body and the needle bar. A groove is provided on the side of the needle handle, and the spring leaf is provided in the groove. The rear section of the spring leaf is a fixed section fixedly connected to the bottom of the groove, and the front section of the spring leaf is formed as a curved section protruding outward from the groove. A needle hook insertion hole is formed between the spring leaf and the needle handle for the knitting needle hook to pass through during transfer knitting. The connecting section between the fixed section and the curved section is formed into a stepped second transfer section, which fits at the bottom of the groove and corresponds to the first transfer section. To ensure smooth sliding of the needle in the needle groove, a circular groove in the thickness direction is usually formed at the needle tail to provide deflection elasticity and enable it to engage with the side wall of the needle groove.

[0003] During the transfer knitting, the yarn is hung on the first transfer loop part and the second transfer loop part of the feeding needle. Through the sliding of the feeding needle and the receiving needle in the needle groove, the hook of the receiving needle first penetrates the needle hook plug hole and then slides backward in the length direction of the feeding needle to the corresponding positions of the first transfer loop part and the second transfer loop part. Then the hook of the receiving needle moves up in the width direction of the feeding needle handle and then moves forward in the length direction of the receiving needle to hook the coil. During the movement of the receiving needle hook, the connection part of the spring piece bent section and the connecting section that fits with the bottom of the groove is supported away from the bottom of the groove. The spring piece has resistance to the sliding of the connecting needle hook. The yarn forms a pulling force on the spring piece to make the spring piece lean against the needle handle. The sliding of the connecting needle between the spring piece and the needle handle increases the resistance. These resistances are likely to affect the running stability of the receiving needle and are also likely to cause the spring piece to be deformed and damaged by excessive force.
