Flat knitting machine needle

Abstract

The invention relates to a flat knitting machine needle comprising a needle bar, a needle latch and a needle end. One end of the needle bar bends to form a needle hook, the other end of the same forms the needle end, and the needle latch is pivoted at the front end of the needle bar to be in formation of opening or closing with the needle hook; when the needle latch looses thread, the perpendicular distance between the tip a of the needle latch and the top end d at an elastic place where the needle latch is pivoted to the needle bar ranges from 1.5mm to 1.8mm; the perpendicular distance between the tip a of the needle latch and the top end f at a place where the needle latch is pivoted to the needle bar ranges from 1.8mm to 2mm; when the needle latch looses the thread, a certain camber is formed on the opposite side of the needle latch on the needle bar; when the needle latch and the needle hook are closed, the needle latch forms a V-shaped included angle with the needle hook, and the needle latch faces upwards relative to a horizontal line; the perpendicular distance between the tip a of the needle latch and a bent point c of the needle hook is 0.64mm; the distance between the tip a of the needle hook and a bent center b of the needle hook is 4.49mm; the flat bit length of circle expanding piece on the needle bar is 20mm. By the arrangement, the defects that an existing needle is hard to loosen from the thread, less easily to pick up, prone to spewing and the like are overcome, and the flat knitting machine needle is more stable in performance, so that operating efficiency is improved.

Description

technical field [0001] The invention relates to a weaving tool, in particular to a knitting needle for a flat knitting machine. Background technique [0002] The structure of the flat knitting needles used in the prior art generally includes a needle bar, a needle latch, a transfer spring leaf and a spring leaf pivot pin. One end of the needle bar is bent to form a needle hook, and the other end is a needle tail. [0003] The knitting needles of the prior art are often due to unreasonable specification design, such as when the needle latch and the needle hook are closed, because the height of the needle hook is not good or the closing angle of the needle latch and the needle hook is too small, it often occurs that it is difficult to connect the needle during the rapid operation of the machine. Align the wool, the wool is difficult to push the needle latch, and the wool will spit out after entering the needle hook. [0004] Some knitting needles of flat knitting machines ha...
