Description

Nylon zipper with invisible teeth and high strength and wear resistance

Technical Field

The utility model relates to the technical field of nylon zippers, in particular to a nylon zipper with invisible teeth and high strength and wear resistance.

Background

The nylon zipper is formed by winding a central line by using nylon monofilaments through a heating compression mold, two bottom lines of the existing nylon zipper are sewn on the monofilaments of the zipper teeth, and the zipper is limited in wear resistance due to friction between a pull head and the stitching lines when the zipper is pulled and the zipper is closed.

Disclosure of Invention

The utility model aims to provide a nylon zipper with invisible teeth and high strength and wear resistance, so as to solve the problems in the background art.

The technical scheme of the utility model is that the nylon zipper with invisible teeth and high strength and wear resistance comprises a piece of zipper cloth, wherein a small cloth belt is arranged at the bottom of the piece of zipper cloth, and a plurality of teeth are fixedly connected to one sides of the piece of zipper cloth, which correspond to the small cloth belt.

In one embodiment, the top of the chain cloth is provided with an upper thread, the bottom of the small cloth belt is provided with a bottom thread, and the upper thread and the bottom thread which are adjacent are mutually connected.

In one embodiment, the plurality of sprockets are arranged in a linear manner from left to right.

The beneficial effects provided by the utility model are as follows:

1. when the zipper is pulled and the slider is in sliding contact with the zipper teeth and the small cloth belt, the zipper cannot directly slide on the seam, so that the wear resistance of the nylon zipper is greatly improved;

2. the zipper teeth on the left side and the right side of the nylon zipper are respectively sewn with a small cloth belt, so that the zipper teeth are completely invisible, the small cloth belt can convert any color, the appearance of the product matched with clothing and luggage cloth is novel and attractive, and meanwhile, compared with the nylon zipper with the same specification, the transverse tension is enhanced by more than ten percent; the reciprocating test times are more than 1.5 times of that of nylon zipper with the same specification.

fig. 2 is a side view of the present utility model.

In the attached drawings, 1, a chain cloth; 2. a small cloth belt; 3. sprocket teeth; 4. an upper thread; 5. and (5) a bottom line.

Detailed Description

It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other. The technical solution of the present utility model will be further described below with reference to the accompanying drawings of the embodiments of the present utility model, and the present utility model is not limited to the following specific embodiments.

It should be understood that the same or similar reference numerals in the drawings of the embodiments correspond to the same or similar components. In the description of the present utility model, it should be understood that, if there are terms such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", etc., that indicate an azimuth or a positional relationship based on the directions or the positional relationships shown in the drawings, it is only for convenience of describing the present utility model and simplifying the description, but not for indicating or suggesting that the apparatus or element to be referred to must have a specific azimuth, be constructed and operated in a specific azimuth, so that the terms describing the positional relationship in the drawings are merely for exemplary illustration and should not be construed as limitations of the present patent, and that the specific meanings of the terms described above may be understood by those skilled in the art according to specific circumstances.

In one embodiment, as shown in fig. 1 and 2, the nylon zipper with invisible teeth and high strength and wear resistance comprises a piece of zipper cloth 1, wherein a small cloth belt 2 is arranged at the bottom of the piece of zipper cloth 1, a plurality of pieces of zipper teeth 3 are fixedly connected to one side corresponding to the piece of zipper cloth 1 and the small cloth belt 2, an upper thread 4 is arranged at the top of the piece of zipper cloth 1, a bottom thread 5 is arranged at the bottom of the small cloth belt 2, the adjacent upper thread 4 and the bottom thread 5 are mutually connected, and the plurality of pieces of zipper teeth 3 are sequentially arranged linearly from left to right;

the nylon zipper bottom lines are added, and the number of the conventional nylon zipper bottom lines is increased to four, so that the wear resistance of the zipper is better enhanced, and one sewing needle is matched with one hooking needle, so that four groups are formed; the degree of matching between the stitching needle and the hook needle is more precise, and a small cloth belt 2 as wide as the zipper teeth 3 is stitched on the left and right zipper teeth 3 of the nylon zipper respectively; this conceals the teeth 3 and enhances the wear resistance of the zipper.

Working principle: manufacturing a special needle plate group: when the zipper is sewn, two cloth belts are placed below the zipper teeth 3 in the zipper tooth grooves of the needle plate, and four-needle eight-wire design is adopted: adding four hook needles of the zipper stitching machine, wherein one sewing needle is matched with one hook needle, and the four sewing needles are in four groups; then the needle of the zipper stitching machine is fixed on the needle bar, and the needle bar is pulled by a motor to move up and down through a series of gears and cams. When the tip of the needle passes through the fabric, it pulls a small loop on one side towards the other, the device under the fabric will grasp this loop and then wrap it around another thread or another loop of the same thread, alternately stitch the loops, the stitch firmly holding the tape, sprocket 3, tapes 2 together.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
