Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

Example 1

The utility model provides an automatic reset sinker, as shown in the figure, including the sinker body, the sinker body is including pressing yarn portion 1, main part 2, heel portion 3 and shell fragment portion 4, both ends are equipped with preceding stroke hole 21 and back stroke hole 22 respectively around the main part 2, preceding stroke hole 21 and back stroke hole 22 are the slotted hole, can hold the steel wire in preceding stroke hole 21 and the back stroke hole 22 and be used for fixing a position the sinker body, the sinker body uses stroke hole distance to move a certain distance as spacing, still be equipped with down stroke hole 11 on pressing yarn portion 1, hold the steel wire in the down stroke hole 11 and be used for fixing a position and press yarn portion 1, the edge of pressing yarn portion 1 is equipped with presses yarn hook 12 and tractive hook 13, press yarn hook 12 to be close to the setting of main part 2 and be located main part 2 upside, tractive 13 is located the tip edge of pressing yarn portion 1 extending direction, down stroke hole 11 is located the draw hook of main part 2 tip department between pressing yarn hook 12 and tractive hook 13.

The lower stroke hole 11 is a long hole, and the inner diameter of the lower stroke hole 11 facing the pulling hook 13 is larger than the inner diameter of the lower stroke hole 11 facing the yarn pressing hook 12. By forming the reducing holes 11 at the lower part, the displacement angle of the sinker can be corrected at the narrower upper limit position when the sinker is displaced.

The yarn pressing part 1 and the heel part 3 are respectively positioned at the front end and the rear end of the main body part 2, the elastic sheet part 4 is connected with the front end of the main body part 2 and positioned below the main body part 2 and extends towards the rear end, and the yarn pressing part 1, the main body part 2, the heel part 3 and the elastic sheet part 4 are integrally molded.

The elastic sheet part 4 is arc-shaped.

The heel portion 3 is tilted upward and forms a recess with the rear end of the main body portion 2. The sinker heel 3 can displace the sinker body when contacting the sinker triangle or when pressing the sinker heel 3.

The thickness of the main body part 2 is larger than that of the yarn pressing part 1, the thickness of the main body part 2 is 0.4-0.5 mm, and the thickness of the yarn pressing part 1 is 0.12-0.2 mm. Increasing the thickness of the main body part 2 while ensuring the thickness of the presser foot 1 increases the sinker body strength, and in addition, thinner presser hooks 12 can form smaller loops.

The thickness of the heel portion 3 and the spring portion 4 is the same as that of the main body portion 2.
