[0032] like Figure 1 and Figure 2 As shown, the nylon antimony-free zipper includes a slider 1 and a pull tab. The slider 1 is used to engage with the chain teeth. The pull tab is sheet-shaped and the inner end of the pull tab is movably connected to the upper part of the slider 1. The pull tab includes a body 2 in the form of a long sheet. The inner end of the body 2 has a penetrating connection hole 2a. The outer end of the body 2 is an operating part 2b for the user to pull, and the operating part 2b has a flexible contact component.

[0033] The slider 1 and the pull tab are both made of nylon material, and antimony-free environmentally friendly additives are used during the preparation of the slider and the pull tab to ensure the safety and environmental friendliness of the slider 1 and the pull tab 2.

[0034] The connecting hole 2a at the inner end of the body 2 is used for movably connecting with the slider 1, and the operating portion 2b at the outer end of the body 2 is used for the operator to conveniently pull the slider.

[0035] In this embodiment, since the operating portion 2b has a flexible contact component, the flexible contact component can improve the comfort during the process of pulling the pull tab.

[0036] The inner end of the body 2 has a U-shaped buckling section 2c, and the buckling section 2c is movably connected to the slider 1.

[0037] The U-shaped notch of the buckling section 2c is fixedly connected to the inner end of the body 2, that is, the above-mentioned connecting hole 2a is formed between the buckling section 2c and the end of the body 2, through which the inner end of the body 2 can be stably and movably connected to the slider 1.

[0038] The slider 1 further comprises a transition ring 3 , one end of which is movably connected to the slider 1 , and the buckling section 2 c is movably connected to the other end of the transition ring 3 .

[0039] The provision of the transition ring 3 can increase the range of motion of the pull tab, ensuring that the pull tab is smoother during the pulling process.

[0040] The flexible contact component is located at the outer end of the pull tab.

[0041] The flexible contact assembly includes a frame 4 and a nylon sleeve 5. The outer end of the body 2 has a penetrating positioning hole 2d. The nylon sleeve 5 is wrapped around the outer side of the frame 4 to form a contact piece. The contact piece is tightly connected to the positioning hole 2d.

[0042] The nylon sleeve 5 is made of a flexible membrane-like material, which can avoid excessive rigid contact when touching the pull tab. Appropriate flexibility can improve the comfort of pulling the pull tab.

[0043] The end of the skeleton 4 has a recessed positioning notch 4a, and the end of the nylon sleeve 5 is tightly pressed against the inner edge of the positioning notch 4a and the positioning hole 2d.

[0044] Under the action of the positioning notch 4 a , the entire contact piece can be stably connected to the outer end of the body 2 in a tight fit.

[0045] The outer side of the nylon sleeve 5 is spherical and there is a smooth transition between the nylon sleeve 5 and the pull tab.

[0046] This can appropriately improve the structural compactness of the body 2.

[0047] The side of the skeleton 4 is provided with a concave avoidance recess 4 b , and the avoidance recess 4 b is provided with a flexible buffer filling body 6 , and the buffer filling body 6 is enclosed between the nylon sleeve 5 and the skeleton 4 .

[0048] Under the action of the buffer filling body, the buffering performance and pressing comfort of the flexible contact component can be further improved.

[0049] There are two avoidance recesses 4b, which are respectively located on both sides of the frame 4. Each avoidance recess 4b has a buffer filling body 6 corresponding thereto.

[0050] Such a structure can make the contact areas on both sides of the pull tab relatively soft.

[0051] The buffer filling body 6 is made of silica gel. According to actual conditions, it is also feasible that the buffer filling body 6 is made of sponge.

[0052] The slider and tab of this nylon antimony-free zipper are both made of nylon material. Nylon (polyamide) is a synthetic fiber. The slider and tab made of this material have good strength and wear resistance. In addition, environmentally friendly additives that do not contain antimony are used in the preparation process of the slider and tab, ensuring the safety and environmental protection of the slider and tab.

[0053] Since the outer end of the pull tab is provided with a flexible contact component, the pull tab can be appropriately deformed when it is pulled, and the operation feels better.

[0054] At the same time, the appropriately deformed flexible contact component can also increase the friction resistance, so that the pull tab can be pulled stably even in the presence of rain, and its stability is relatively high.

[0055] The various technical features of the above-described embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the various technical features in the above-described embodiments are described.
