By arranging multiple chain teeth on the cloth strip of the cloth bag, a zipper is made, which is widely used in clothing, tents, etc. However, the existing chain teeth have the problem of high edge sharpness. When sewn on fabrics such as clothing, they are likely to cause snagging, resulting in burrs, damaging the fabric, and being rather uncomfortable to the touch when in use. Summary of the Utility Model
[0003] Based on this, it is necessary to provide an anti-hooking and stabbing chain tooth, a processing die for the chain tooth, and a zipper with low edge sharpness and not prone to snagging and generating burrs.

[0005] An anti-hooking and stabbing chain tooth, the anti-hooking and stabbing chain tooth includes a tooth main body, a tooth neck, and a tooth head. The tooth neck is arranged between the tooth main body and the tooth head and is respectively connected to the tooth main body and the tooth head. Along the length direction of the tooth main body, one end of the tooth head away from the tooth neck has a first surface. Along the width direction of the tooth main body, the side part of the tooth head has a second surface. Along the height direction of the tooth main body, the end part of the tooth head has a third surface. A tooth groove is arranged on the first surface. The second surface and the first surface are connected by an arc transition. The third surface and the first surface are connected by a first chamfer. The radius of the first chamfer is R, and 0.9 mm ≤ R ≤ 1 mm.
[0006] It can be understood that by arranging the tooth main body, the tooth neck, and the tooth head in the present application, the second surface of the tooth head between the first surface of the tooth head away from the tooth neck and the side part of the tooth head is connected by an arc transition, increasing the smoothness of the connection part. And the third surface of the end part of the tooth head and the first surface are connected by a first chamfer, and the radius R of the first chamfer is set to 0.9 mm ≤ R ≤ 1 mm, increasing the radian at the first chamfer, reducing the edge sharpness of the tooth head, making it smoother, so that it is not easy to snag the fabric of clothing and the like contacted by the chain tooth, and at the same time improving the touch of the chain tooth.
[0007] In one embodiment, a second chamfer is circumferentially arranged at the opening of the tooth groove, and the second chamfer is respectively connected to the first surface and the second surface by an arc transition.
[0008] It can be understood that the setting of the second chamfer makes the connection between the first surface and the second surface have a radian, increasing the smoothness of the connection position, thereby reducing the sharpness at this connection position.
[0009] In one embodiment, along the height direction of the tooth body, the tooth groove divides the first surface into two half surfaces, and each half surface is transitionally connected to the third surface through the first chamfer; wherein, along the height direction of the tooth body, and the first chamfer extends at least to the 1 / 3 position of the half surface.
[0010] It can be understood that the zipper is formed by the cooperation of two rows of evenly arranged chain teeth, and the two half surfaces formed by the tooth groove dividing the first surface can be respectively matched with the chain teeth at the corresponding positions of the other row of the zipper one by one. Moreover, the transitional connection between the half surface and the third surface makes the connection between the two surfaces of the tooth head smoother, thereby increasing the roundness of the chain teeth; at the same time, the first chamfer extends at least to the 1 / 3 position along the height direction of the tooth body of the half surface, further ensuring that the tooth head where the chain teeth cooperate with each other can be more round, thereby further reducing the edge sharpness of the tooth head.
[0011] In one embodiment, along the width direction of the tooth body, the side part of the tooth body has a fourth surface, and along the height direction of the tooth body, the end part of the tooth body has a fifth surface; the fourth surface and the fifth surface are transitionally connected through a third chamfer.
[0012] It can be understood that the transitional connection between the fourth surface and the fifth surface through the third chamfer can make the connection between the two surfaces of the tooth body more rounded, further increasing the smoothness of the chain teeth.
[0013] In one embodiment, along the length direction of the tooth body, a sixth surface is provided on the side part of the tooth neck, and a seventh surface is provided at the end part of the tooth neck; the sixth surface and the seventh surface are transitionally connected through a fourth chamfer; and, along the length direction of the tooth body, the third chamfer, the fourth chamfer and the first chamfer are connected.
[0014] It can be understood that the setting of the fourth chamfer connecting the sixth surface and the seventh surface makes the connection between the two smoother, thereby reducing the edge sharpness of the chain teeth; and the connection of the third chamfer, the fourth chamfer and the first chamfer ensures the smoothness of the chain tooth structure and makes the touch better.
[0015] In one embodiment, a protrusion is provided on the sixth surface.
[0016] It can be understood that the chain teeth in the same row and adjacent positions on the zipper can be correspondingly connected through the protrusions, thereby increasing the tightness of the connection between the chain teeth in the same row.
[0017] In one embodiment, the second surface is configured as a smooth curved surface.
[0018] It can be understood that the setting of the smooth curved surface makes the chain teeth smoother, further reducing the occurrence of snagging of the chain teeth, and making its touch smoother.
[0019] In one embodiment, the tooth body, the tooth neck and the tooth head are integrally formed by machining.
[0020] It can be understood that the integral machining not only reduces the connection structure of the chain teeth, making them more round, smooth and stable in structure, but also simplifies the production line for the integral machining of the chain teeth, thereby reducing its production and processing costs and saving costs.

[0037] Please refer to Figure 1 and Figure 2 , this application provides an anti-hooking chain tooth 100, which is applied to the manufacture of zippers and mainly serves as the main body of the zipper. It is sewn on fabrics such as clothing and cloth bags, is not easy to snag and generate burrs, and reduces the edge sharpness, improving the touch of the zipper.
[0038] As Figure 1 and Figure 2 shown, the anti-hooking chain tooth 100 includes a tooth main body 10, a tooth neck 20 and a tooth head 30. The tooth neck 20 is arranged between the tooth main body 10 and the tooth head 30 and is connected to the tooth main body 10 and the tooth head 30 respectively; along the length direction x of the tooth main body 10, one end of the tooth head 30 away from the tooth neck 20 has a first surface 31, along the width direction y of the tooth main body 10, the side part of the tooth head 30 has a second surface 32; along the height direction z of the tooth main body 10, the end part of the tooth head 30 has a third surface 33; a tooth groove 311 is provided on the first surface 31, the second surface 32 is connected to the first surface 31 by an arc transition, and the third surface 33 is connected to the first surface 31 by a first chamfer 34, and the radius of the first chamfer 34 is R, 0.9mm ≤ R ≤ 1mm.
[0039] It should be noted that when the chain teeth are applied to fabrics such as clothing and cloth bags, the high sharpness of the edges of the chain teeth will cause burrs on the fabric, damage the fabric, and the touch will also be poor during use. In this application, by providing the tooth body 10, the tooth neck 20, and the tooth head 30, an arc transition connection is made between the first surface 31 where the tooth head 30 is away from the tooth neck 20 and the second surface 32 on the side of the tooth head 30, increasing the smoothness of the connection part. And the third surface 33 at the end of the tooth head 30 is connected to the first surface 31 through the first chamfer 34, and the radius R of the first chamfer 34 is set to 0.9 mm ≤ R ≤ 1 mm, increasing the radian at the first chamfer 34, reducing the sharpness of the edge of the tooth head 30, making it smoother, so that it is not easy to snag the fabric of clothing and the like contacted by the anti-snagging chain teeth 100, and at the same time improving the touch of the anti-snagging chain teeth 100.
[0040] Preferably, the value of the radius R of the first chamfer 34 can be 0.9 mm, 0.91 mm, 0.92 mm, 0.93 mm, 0.94 mm, 0.95 mm, 0.96 mm, 0.97 mm, 0.98 mm, 0.99 mm, 1 mm and other values. Of course, within the range of the value of the radius R of the first chamfer 34, other values can be selected according to actual needs.
[0041] Here, the value of the radius R cannot be too small, otherwise the edge sharpness will be small and spines are likely to appear; nor can it be too large, otherwise the edge sharpness will be too large and too smooth, resulting in the inability to mesh tightly between two rows of corresponding anti-snagging chain teeth 100 installed on the chain. Therefore, in this embodiment, the radius R of the first chamfer 34 is set to 0.9 mm ≤ R ≤ 1 mm.
[0042] In one embodiment, please refer to Figure 1 , along the width direction y of the tooth body 10, the side of the tooth body 10 has a fourth surface 11, and along the height direction z of the tooth body 10, the end of the tooth body 10 has a fifth surface 12; the fourth surface 11 and the fifth surface 12 are transitionally connected through a third chamfer 13. In this way, the connection between the fourth surface 11 and the fifth surface 12 is smoother, so that the connection between the width direction y and the height direction z of the tooth body 10 is smooth, so as to improve the touch of the tooth body 10 part and its snagging situation on the applied fabric.
[0043] Please continue to refer to Figure 1, in the length direction x of the tooth main body 10, a sixth surface 21 is provided on the side of the tooth neck 20, and a seventh surface 22 is provided at the end of the tooth neck 20. The sixth surface 21 and the seventh surface 22 are connected by a fourth chamfer 23 in a transitional manner; moreover, along the length direction x of the tooth main body 10, the third chamfer 13, the fourth chamfer 23, and the first chamfer 34 are connected. The fourth chamfer 23 is provided to connect the sixth surface 21 and the seventh surface 22, making the connection between the two smoother, thereby reducing the edge sharpness of the anti-hooking chain tooth 100 and further making it less likely to snag the fabric.
[0044] Such as Figure 1 and Figure 2 , the tooth head 30, the tooth main body 10, and the tooth neck 20 are integrally processed and formed. The integral processing and forming not only reduce the connection structure of the anti-hooking chain tooth 100, making it more round, smooth, and structurally stable, but also the integral processing of the anti-hooking chain tooth 100 can simplify the production line, thereby reducing its production and processing costs and saving costs.
[0045] In an embodiment, please continue to refer to Figure 1 , along the height direction z of the tooth main body 10, the tooth groove 311 divides the first surface 31 into two half surfaces 312, and each half surface 312 is connected to the third surface 33 by a first chamfer 34 in a transitional manner; a zipper is formed by the mutual cooperation of two rows of evenly distributed chain teeth. The two half surfaces 312 divided by the tooth groove 311 can be meshed and misalignedly connected with the anti-hooking chain teeth 100 at the corresponding positions of the zipper, and the transitional connection between the half surface 312 and the third surface 33 makes the connection of the tooth head 30 smoother, so as to increase the smoothness of the anti-hooking chain tooth 100.
[0046] Furthermore, the second surface 32 is configured as a smooth curved surface. It can be understood that the setting of the smooth curved surface makes the anti-hooking chain tooth 100 smoother, reduces the occurrence of snagging, and makes its touch smoother.
[0047] Preferably, along the height direction z of the tooth main body 10, the first chamfer 34 extends at least to the 1 / 3 position of the half surface 312. In this way, the smoothness of the meshing and misalignment fitting part of the anti-hooking chain tooth 100 is further ensured, thereby reducing the edge sharpness of the tooth head 30 so that it is not easy to snag.
[0048] Exemplarily, the first chamfer 34 can extend to at least 1 / 3 positions such as 1 / 2, 3 / 5, 1 / 3, etc. of the half surface 312 along the height direction z of the tooth main body 10 to ensure low sharpness at this position. In this embodiment, the first chamfer 34 extends to the 1 / 2 position of the half surface 312 along the height direction z of the tooth main body 10.
[0049] Preferably, along the length direction x of the tooth body 10, the first chamfer 34, the third chamfer 13, and the fourth chamfer 23 are connected. In this way, the smoothness of the structure of the anti-hooking chain tooth 100 is ensured, and its touch is better.
[0050] Furthermore, a second chamfer 35 is circumferentially provided at the opening 313 of the tooth groove 311, and the second chamfer 35 is arc-transitionally connected to the first surface 31 and the second surface 32 respectively. It can be understood that the setting of the second chamfer 35 makes the connection between the first surface 31 and the second surface 32 have a radian, increasing the smoothness of the connection position, thereby reducing the sharpness at the connection position.
[0051] Please continue to refer to Figure 1 and Figure 2 , and a protrusion 40 is provided on the sixth surface 21. The anti-hooking chain teeth 100 at the same column and adjacent positions of the zipper can be correspondingly connected through the protrusion 40, thereby increasing the tightness of the connection between the anti-hooking chain teeth 100 in the same column.
[0052] Exemplarily, among two adjacent anti-hooking chain teeth 100, a protrusion 40 is provided on one of the sixth surfaces 21, and in the other anti-hooking chain tooth 100, a tooth groove 311 is provided on the first surface 31. In this way, the protrusion 40 cooperates with the corresponding tooth groove 311.
[0053] Preferably, a chamfer is provided on each edge of the protrusion 40, so that the whole protrusion 40 is also relatively smooth, further avoiding the appearance of barbs.
[0054] The present application also provides a chain tooth processing mold. The chain tooth processing mold is used to process the anti-hooking chain tooth 100 in any of the above embodiments. A feeding port (not shown in the figure) is provided on the chain tooth processing mold, and the caliber of the feeding port is set to 0.65 mm - 0.7 mm. It can be understood that the chain tooth processing mold can be used to produce the above anti-hooking chain tooth 100, and the caliber of the inlet material of the mold is set to 0.65 mm - 0.7 mm. This value should not be too large, otherwise when pouring the mold to produce the anti-hooking chain tooth 100, redundant parts will be generated on the anti-hooking chain tooth 100 at the feeding port, and the redundant parts will make the anti-hooking chain tooth 100 easy to hook the fabric; nor should it be too small, otherwise it will affect the pouring of the mold. Therefore, controlling the caliber of the feeding port of the mold to be 0.65 mm - 0.7 mm can increase the flatness of the anti-hooking chain tooth 100 and further improve the smoothness of the anti-hooking chain tooth 100.
[0055] Preferably, the caliber value of the feed inlet can be 0.65mm, 0.66mm, 0.67mm, 0.68mm, 0.69mm, 0.7mm, etc. Of course, within this range, the caliber value of the feed inlet can also be selected and set according to actual needs.
[0056] As Figure 2 shown, the present application provides a zipper 200, and the zipper 200 includes the anti-hooking chain teeth 100 in any of the above embodiments.
[0057] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
[0058] The above-described embodiments only express several implementation manners of the present application. The description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
