Description

Crochet hook wire pulling structure

Technical Field

The invention relates to a thread pulling structure, in particular to a crochet hook thread pulling structure.

Background

The magnetic ring is a common anti-interference element in an electronic circuit, has a good effect of inhibiting high-frequency noise, and is generally made of ferrite materials. The magnetic ring has different impedance characteristics at different frequencies, and generally has small impedance at low frequencies, and the impedance of the magnetic ring increases sharply when the signal frequency increases. It is known that the higher the frequency of the signal, the easier it is to radiate, and the general signal lines are all without shielding layers, so that these signal lines become very good antennas to receive various messy high frequency signals in the surrounding environment, and these signals are superimposed on the originally transmitted signals, and even change the originally transmitted useful signals. Under the action of the magnetic ring, normal useful signals can pass well, high-frequency interference signals can be well restrained, and the cost is low.

The T2 magnetic ring is one type of magnetic ring. When the T2 magnetic ring is wound, the copper wire on the T coil needs to be accurately conveyed to the crochet hook through the wire pulling block, and the crochet hook needs to accurately hook the copper wire to enable the copper wire to be wound on the T2 magnetic ring. However, the copper wire is very tiny and tough and slippery, so that the copper wire is easily and uncontrollably deviated from the preset wire feeding position, the copper wire is often not fed in place, and the magnetic ring winds around, and finally defective products are caused. For this purpose, a crochet hook thread pulling structure is proposed by a person skilled in the art to solve the problems presented in the background above.

Detailed Description

The technical scheme of the patent is further described in detail below with reference to the specific embodiments.

Embodiment one: referring to fig. 1, a crochet hook wire pulling structure comprises a base 1, a wire pulling block 2, copper wires 5, a crochet hook 6 and a wire pulling hook 7, wherein the wire pulling block 2 is slidably connected to the inner side of the base 1, and the wire pulling block 2 is arc-shaped.

The front end face of the wire pulling block 2 is fixedly connected with a protrusion 3.

The bottom of the wire pulling block 2 is provided with a V-shaped opening 4.

The front end face of the wire pulling block 2 is fixedly connected with an anti-slip layer, and the anti-slip layer is made of felt.
