By arranging a shrinkage notch on the hanging piece, when the hanging piece is pressed into the lower sleeve, the hanging piece shrinks along the circumferential direction. When the hanging piece is pressed into place, the hanging piece automatically resets to form a stable connection with the lower sleeve. The pressing process can avoid deformation and damage of the lower sleeve caused by pressing the hanging piece, thereby reducing the scrap rate during bottle cap assembly.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] The anti-pulling component which is easy to assemble comprises a hanging piece which is arranged in a lower sleeve and has a shrinkage notch. When the hanging piece is pressed into the lower sleeve, the hanging piece shrinks in the circumferential direction.

[0007] Furthermore, a mounting groove is provided in the lower sleeve, and the hanging piece is arranged in the mounting groove.

[0008] Furthermore, the hanging piece includes a connecting portion and a bottle hanging portion, the connecting portion is a circular sleeve-shaped structure, and the bottle hanging portion is a plurality of hanging teeth arranged on the inner circumferential wall of the connecting portion;

[0009] The shrinkage notch is arranged on the connecting portion; and the connecting portion is adapted to the mounting groove.

[0010] Furthermore, the lower sleeve is provided with a guide groove along the axial direction, and one end of the shrinkage notch is provided with a guide rib matched with the guide groove.

[0011] Furthermore, the outer diameter of the connecting portion is larger than the inner diameter of the lower sleeve, and the inner diameter of the connecting portion is smaller than the inner diameter of the lower sleeve.

[0012] Furthermore, the hanging piece is made of metal material.

[0013] Furthermore, the hanging sheet is made of alloy or single metal.

[0014] The beneficial effects of the utility model are:

[0015] The utility model provides a shrinkage notch on the hanging piece, and when the hanging piece is pressed into the lower sleeve, the hanging piece shrinks in the circumferential direction, and when the hanging piece is pressed into place, the hanging piece automatically resets to form a stable connection with the lower sleeve, and the pressing process can avoid deformation and damage of the lower sleeve caused by pressing the hanging piece, thereby reducing the scrap rate during bottle cap assembly.

[0019] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 2 , the utility model provides a technical solution:

[0021] Example:

[0022] like Figure 1 and Figure 2 As shown, an anti-pulling component that is easy to assemble includes a hanging piece 1, which is arranged in a lower sleeve 2. A shrinkage notch 3 is provided on the hanging piece 1. When the hanging piece 1 is pressed into the lower sleeve 2, the hanging piece 1 shrinks along the circumferential direction.

[0023] The lower sleeve 2 is provided with a mounting groove 4 , and the hanging piece 1 is arranged in the mounting groove 4 .

[0024] The hanging piece 1 includes a connecting portion 5 and a bottle hanging portion 6, wherein the connecting portion 5 is a circular sleeve-shaped structure, and the bottle hanging portion 6 is a plurality of hanging teeth arranged on the inner circumferential wall of the connecting portion 5;

[0025] The shrinkage notch 3 is arranged on the connecting portion 5 ; the connecting portion 5 is adapted to the mounting groove 4 .

[0026] The outer diameter of the connecting portion 5 is larger than the inner diameter of the lower sleeve 2 , and the inner diameter of the connecting portion 5 is smaller than the inner diameter of the lower sleeve 2 .

[0027] The hanging piece 1 is made of metal material.

[0028] The hanging piece 1 is made of alloy or single metal.

[0029] The lower sleeve 2 is provided with a guide groove 7 along the axial direction, and one end of the shrinkage notch 3 is provided with a guide rib 8 matched with the guide groove 7 .

[0030] Working principle: During press-fitting, the guide ribs 8 are guided by the guide grooves 7, and the hanging piece 1 contracts when passing through the fixed area below the lower sleeve 2.

[0031] When the connecting portion 5 of the hanging piece 1 enters the installation groove 4, the squeezing of the inner wall of the lower sleeve 2 on the blocking piece disappears, and the hanging piece 1 automatically returns to its original size, and the connecting portion 5 cooperates with the installation groove 4 to form a stable connection between the hanging piece 1 and the lower sleeve 2.
