[0039] A cloth tape 1, a cloth blocking area 11, a folding and sewing area 12, an outer edge binding 121, a full-round edge binding 122, a semi-round edge binding 123, an installation area 13, a chain tooth 2, a slider 3, an upper wing plate 31, a side wing plate 32, a lower wing plate 33, a middle wing plate 34, a double-side wing plate 35, an upper outer wing plate 36, and a lower outer wing plate 37. Specific implementation manner

[0040] The core of the present utility model is to provide an anti-jamming zipper, which can simply achieve the effect of preventing the slider from jamming the cloth.

[0041] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the anti-jamming zipper of the present utility model will be introduced and described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0042] Combined with Figure 2 、 Figure 3 As shown, the present utility model provides an anti-jamming zipper, including a cloth tape 1, a chain tooth 2, and a slider 3. The cloth tape 1 is a woven structure and serves as an installation and bearing function; the cloth tape 1 includes a cloth blocking area 11, a folding and sewing area 12, and an installation area 13 in sequence along the width direction. The cloth tape 1 is a complete fabric structure, which is sequentially divided into a cloth blocking area 11, a folding and sewing area 12, and an installation area 13. The cloth blocking area 11, the folding and sewing area 12, and the installation area 13 are connected in sequence, and the widths of the three are not strictly limited and can be set according to the usage requirements.

[0043] A chain tooth 2 is installed at the edge of the installation area 13. The folding and sewing area 12 is used for folding to make the cloth blocking area 11 fold towards the installation area 13. After folding, the folding and sewing area 12 forms a crease; after folding, the cloth blocking area 11 can cover the upper surface of the slider 3, and the edge position of the cloth blocking area 11 presses on a part of the edge of the upper surface of the slider 3. The cloth blocking area 11 can press on the slider 3 to block the gap between the upper surface of the cloth tape 1 and the slider 3. After folding, the cloth blocking area 11 is close to the installation area 13, and the fabric structure of the folding and sewing area 12 forms an overlap. After folding, the folding and sewing area 12 can be sewn and connected to the fabric, for example, sewn at the front opening of a garment or the opening of a bag.

[0044] During the use process, the gap between the slider 3 and the fabric is blocked by the cloth blocking area 11. The cloth blocking area 11 has a blocking effect on the fabric. The contact between the cloth blocking area 11 and the slider 3 can prevent the fabric from entering the gap of the slider 3, thereby effectively preventing the occurrence of cloth jamming. The entire anti-cloth-jamming structure is realized by folding the fabric, which is relatively simple for the production of the cloth tape and plays a role in simplifying the production.

[0045] For a zipper, two fabric tape structures are required. The two fabric tape structures can adopt the same structure and be symmetrically arranged. Both share the same slider 3. When the slider 3 is closed, the two rows of chain teeth 2 can be interlaced and meshed with each other.

[0046] Based on the above scheme, combined with Figure 4 , Figure 5 , Figure 6 , Figure 11 , Figure 12 As shown, the slider 3 of the utility model includes an upper wing plate 31, a side wing plate 32 and a lower wing plate 33. The two side wing plates 32 are respectively fixed to the two side edges of the upper wing plate 31, and the two lower wing plates 33 are respectively fixed to one of the side wing plates 32. The upper wing plate 31, the side wing plates 32 and the lower wing plate 33 form a semi-enclosed structure in the shape of a Chinese character "匚", and the chain teeth 2 can enter the semi-enclosed structure and be pulled together; a gap is formed between the lower wing plates 33 for the cloth of the installation area 13 to pass through, so that the cloth of the cloth tape 1 can pass through.

[0047] Combination Figure 4 , Figure 5 , Figure 6 After assembly is completed, the bottom surface of the slider 3 can contact the upper surface of the installation area 13 to cover the gap below the slider 3. The slider 3 is wrapped in the area formed by the installation area 13. The gap below the slider 3 is completely wrapped by the installation area 13. The lower surface of the slider 3 cannot contact the fabric, thereby avoiding the phenomenon of fabric getting stuck in the gap.

[0048] Combination Figure 4 , Figure 5 , Figure 6 After assembly, the cloth blocking area 11 remains horizontal, so that the outer surface maintains a flat appearance; the installation area 13 bends downward, and the structure formed by the bending of the installation area 13 maintains a conforming state with the slider 3, and the shape of the installation area 13 is roughly consistent with the shape of the slider 3. A full-range anti-cloth structure formed by a non-pressure slider and corresponding cloth tape is adopted.

[0049] Figure 4 In the structure, the folded sewing area 12 is folded to form an overlapping area of a double layer of fabric, which can be used for sewing with fabrics such as clothing; and no hemming structure is provided at the fold.

[0050] Figure 5 In the structure shown, the outer fold line formed by folding the folding sewing area 12 is covered with an outer edge 121, which is arranged on the outer surface of the folding sewing area 12. The outer edge 121 can be sewn outside the fold using a separate piece of fabric. The outer edge 121 can be sewn after the folding sewing area 12 is folded and overlapped, or before it is folded. Figure 3Schematic diagram showing that the outer edge 121 is sewn to the folding and sewing area 12 before folding.

[0051] Combined with Figure 6 As shown, the folding and sewing area 12 can also adopt a pre-woven cylindrical structure. Combined with Figure 7 , the folding and sewing area 12 is woven to form a complete circular edge 122 of a cylinder. The complete circular edge 122 is a complete arc structure. Different knitting stitches are used at the edge position when knitting the folding and sewing area 12. For example Figure 10 As shown, an arc-shaped area is formed at the complete circular edge 122 after knitting. Other areas of the folding and sewing area 12 are flat. When folded, the complete circular edge 122 forms a complete cylindrical structure.

[0052] Combined with Figure 8 , in addition to adopting the complete circular edge 122, the folding and sewing area 12 is woven to form two semi-circular edges 123. Different knitting stitches are used at the edge position when knitting the folding and sewing area 12. Two arc-shaped areas are formed at the two semi-circular edges 123. Other areas of the folding and sewing area 12 are flat. When folded, the two semi-circular edges 123 can form a complete cylindrical structure.

[0053] Figure 7 、 Figure 8 The complete circular edge 122 and the semi-circular edge 123 adopted are prefabricated and processed, without the need to additionally add an edge sewing process, which simplifies the operation, and the formed edge structure is cylindrical, which is more beautiful.

[0054] Combined with Figure 9 As shown, which shows a knitting form of the folding and sewing area 12, in which the folding line of the folding and sewing area 12 is knitted and folded in half, that is, after knitting and forming, the folding and sewing area 12 naturally forms a folded state, which can further reduce a folding and shaping process and can further simplify the production process.

[0055] Combined with Figure 13 As shown, the present utility model provides another embodiment herein, in which another row of chain teeth 2 can be installed at the edge of the baffle area 11, that is, the baffle area 11 and the installation area 13 are respectively provided with chain teeth 2. Combined with Figure 14As shown, the slider 3 includes a middle wing plate 34, bilateral wing plates 35, upper outer wing plates 36, and lower outer wing plates 37. The two bilateral wing plates 35 are respectively fixed to the two side edges of the middle wing plate 34. The two upper outer wing plates 36 are respectively fixed to the upper edges of the bilateral wing plates 35, and the two lower outer wing plates 37 are respectively fixed to the lower edges of the bilateral wing plates 35. A space for accommodating the upper chain teeth 2 is formed above the middle wing plate 34, and a space for accommodating the lower chain teeth 2 is formed below the middle wing plate 34. A gap for the fabric of the baffle area 11 to pass through is formed between the two upper outer wing plates 36, and a gap for the fabric of the installation area 13 to pass through is formed between the two lower outer wing plates 37, through which the fabric of the cloth tape 1 can be led out respectively.

[0056] Combined with Figure 13 As shown, the baffle area 11 bends upward, and the installation area 13 bends downward. The whole structure is symmetrically arranged up and down with respect to the horizontal plane.

[0057] Based on any of the above technical solutions and their combinations, the strength of the baffle area 11 and the installation area 13 of the present utility model is greater than that of the folding and sewing area 12, so as to ensure that the folding and sewing area 12 can be folded and maintain a specific shape through the baffle area 11 and the installation area 13. The difference in structural strength can be achieved by different knitting stitches.

[0058] In order to fold and fit more effectively, the cloth tape needs to have a certain degree of softness. The stiffer part of the cloth tape 1 can adopt twill weave, and generally polyester filaments are used in terms of materials. Plain weave can be adopted at the fold seam position for the thin and light effect of the cloth tape.

[0059] In the present utility model, the cloth tape does not need to add additional components. Only by widening the cloth tape and then folding and sewing can the anti-jamming effect of the cloth be achieved. During processing, it can be processed according to the conventional production method of cloth tapes. Compared with the conventional double-layer cloth tape, the production is more convenient and the efficiency is higher.

[0060] The anti-jamming effect of the zipper can be achieved through a simple wide cloth tape. The overall structure is simpler than the existing anti-jamming double-layer cloth tape. The anti-jamming effect can also be achieved on both the inner and outer sides in combination with invisible zippers and non-pressure-sensitive zippers.

[0061] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
