Abstract

The utility model discloses a nylon zipper, which comprises two zipper belts which are respectively fixed on two tooth chains of the opposite edges of the two zipper belts, lower stop buckles which are fixed on the lower end parts of the two tooth chains, and upper stop buckles which are fixed on the upper end parts of the two tooth chains, wherein the upper and the lower stop buckles are extruded between the upper and the lower surfaces of the two zipper belts, and the upper and the lower end parts of the two zipper belts can be connected together; the cross sections of the upper and the lower stop buckles are a shape like the Chinese character 'gong', and the upper and the lower stop buckles are made from thermoplastic plastics material. The nylon zipper has firm connection, and can not be loosened easily by the repeated impact of a slider. Clothing nearing to the nylon zipper can not be scratched easily. When the nylon zipper is arranged in a pillow, human hairs can not be clamped by the nylon zipper. The utility model is more safe and reliable to use.

Description

Nylon zipper

Technical field

The utility model relates to the slide fastener technical field, and relating in particular to a kind of its tooth chain is the slide fastener of being made by nylon material.

Background technology

Known slide fastener comprises two zipper strips, and the opposite edges of two zipper strips are fixed with a tooth chain respectively, on described two tooth chains a slider is installed, and two ends up and down of tooth chain are respectively equipped with the only button and the following button that ends gone up that can prevent the slider slippage.Upper and lower only deduction of points is not the buckle with the bonding jumper bending forming, owing to buckle is to come with the bonding jumper bending, two end is not sealed, thereby these two ends scratch the clothing near it easily, if this slide fastener is installed on pillow, two ends of the buckle that does not seal are also clamped people's hair easily.Moreover, end button or when only detaining down,, buckle is opened, cause slider slippage from the tooth chain because two ends of buckle are not sealed when slider clashes into repeatedly.

The utility model content

Technical problem to be solved in the utility model is: provide a kind of and be connected firmly, be not easy to scratch the nylon zipper near its clothing.

For solving the problems of the technologies described above, the technical solution of the utility model is: nylon zipper, comprise two zipper strips, be individually fixed in two tooth chains of the opposite edges of described two zipper strips, be fixed in the following last button that ends of only detaining and being fixed in the upper end of described two rooted tooth chains of the bottom of described two rooted tooth chains, describedly end down that button is squeezed between the upper and lower surface of two zipper strips and the bottom of two zipper strips is linked together, its cross section is " worker " font, and its material is a thermoplastic.

End button down and be squeezed between the upper and lower surface of two zipper strips, just two zipper strips link together thus, and the cross sectional shape that ends button down is " worker " font, are connected firmly, and slider clashes into repeatedly down and ends button, and it is unclamped; Its material is a thermoplastic, makes it can adopt Shooting Technique, will descend to end the bottom that button is fixed in two zipper strips with injection machine by injection mold.Because the following button that ends of this shape seals, and does not have two ends of opening, thereby is not easy to scratch the clothing near it, when this slide fastener is installed on pillow, can not clamp people's hair, so use safer more reliable.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the cutaway view at A-A place among Fig. 1.

The specific embodiment

Nylon zipper, as shown in Figure 1, by two zipper strip 1a, 1b, two tooth chain 2a, 2b, slider 3 with upper and lowerly only detain 4,5 and form.Article two, tooth chain 2a, 2b are individually fixed in the opposite edges of described two zipper strip 1a, 1b, slider 3 is installed in two tooth chain 2a, 2b, on only detain 4 and be fixed in the upper end of described two rooted tooth chain 2a, 2b and the upper end of two zipper strip 1a, 1b is linked together, only detain 5 down and be fixed in the bottom of two rooted tooth chain 2a, 2b and the bottom of two zipper strip 1a, 1b is linked together.

As shown in Figure 2, only detain 5 down and be squeezed between the upper and lower surface of two zipper strip 1a, 1b, its cross sectional shape is " worker " font, and its material is a thermoplastic.

On only detain 4 identically with the structure of only detaining down 5, be squeezed between the upper and lower surface of two zipper strip 1a, 1b, its cross sectional shape also is " worker " font, its material also is a thermoplastic.

Upper and lower production technology of ending button is as follows: the slide fastener semi-finished product that slider 3 will be installed are positioned on the counterdie of injection mould, and mould, with the plastics melt injection in the die cavity of injection mould, after pressurize, cooling, die sinking.Like this, just make between the upper and lower surface that is squeezed in two zipper strip 1a, 1b in the end of tooth chain, its cross sectional shape is that going up of thermoplastic ended button or ended button down for " worker " font, its material.

Claims

1, nylon zipper, comprise two zipper strips (1a, 1b), be individually fixed in two tooth chains (2a, 2b) of the opposite edges of described two zipper strips (1a, 1b), bottom following that is fixed in described two rooted tooth chains (2a, 2b) ends button (5) and is fixed in the going up to end and detain (4) of upper end of described two rooted tooth chains (2a, 2b), it is characterized in that: describedly end down that button (5) is squeezed between the upper and lower surface of two zipper strips (1a, 1b) and the bottom of two zipper strips (1a, 1b) is linked together, its cross section is " worker " font, and its material is a thermoplastic.

2, nylon zipper as claimed in claim 1, it is characterized in that: describedly go up to end that button (4) is squeezed between the upper and lower surface of two zipper strips (1a, 1b) and the upper end of two zipper strips (1a, 1b) is linked together, its cross sectional shape is " worker " font, and its material is a thermoplastic.
