Description

Technical Field

[0001] This utility model relates to the technology of zippers, and more particularly to a zipper chain (fastener chain). Background Technology

[0002] A typical zipper usually consists of a zipper chain made up of a pair of zipper tapes (fastener tapes) and element columns mounted on the zipper tapes, and a slider mounted on the zipper chain that opens or closes the element columns by sliding the slider along the zipper chain. Furthermore, a stopper located at the end of the element column can be installed on the zipper tape to stop the slider from sliding along the zipper chain.

[0003] In existing technologies, when zipper chains including zipper tapes are used on products (such as parts of clothing, like jacket pockets), the zipper tape affects the product's appearance. Therefore, zipper chains have been developed that replace zipper tapes with cords, i.e., zipper teeth are mounted on a pair of cords on the left and right sides. However, because the cords used in zipper chains are narrow, it's more common to mount the stops on the cords rather than on the cords themselves; therefore, the installation effect and structural strength of the stops are lower.

[0004] Therefore, it is necessary to improve the structure of the zipper chain, including the core wire, to enhance the installation effect and structural strength of the stop installed on the zipper chain including the core wire. Utility Model Content

[0005] This utility model provides a zipper chain that can improve the installation effect and structural strength of the stop installed on the zipper chain including the core wire.

[0006] A zipper chain according to this utility model includes: a pair of core wires extending in the length direction; a pair of chain teeth respectively disposed on the pair of core wires; and a stop disposed on a portion of the pair of chain teeth in an engaged state, wherein the stop includes an outer portion and an inner portion respectively disposed from the outer side and inner side of the pair of chain teeth, one of the outer portion and the inner portion having a pin portion, the other of the outer portion and the inner portion having an opening portion, and at least one of the outer portion and the inner portion having a rib portion, a portion of the pair of chain teeth having a mounting hole for the pin portion to pass through, and a groove portion corresponding to the rib portion, the outer portion and the inner portion of the stop being inserted into the opening portion through the mounting hole of the pin portion and reinforced and disposed on a portion of the pair of chain teeth, and at least a portion of the rib portion being embedded in the groove portion.

[0007] In an embodiment of this utility model, one of the outer portion and the inner portion having the opening is provided with a receiving recess, the opening is formed in the receiving recess, and a portion of the reinforced pin portion is located in the receiving recess.

[0008] In an embodiment of the present invention, the rib portion includes a plurality of first ribs extending in the width direction, and the groove portion includes at least one groove extending in the width direction.

[0009] In an embodiment of the present invention, at least one of the plurality of first protruding ribs is embedded in at least one of the grooves, and at least another of the plurality of first protruding ribs is embedded in the gap between two adjacent chain teeth in the chain tooth row.

[0010] In an embodiment of the present invention, the rib portion includes a plurality of second ribs extending in the length direction and connecting the plurality of first ribs, and the plurality of second ribs act as outer sidewalls abutting the outer side surfaces of a pair of chain teeth on opposite sides in the width direction.

[0011] In an embodiment of the present invention, the rib portion includes at least one rib extending in the length direction, and the groove portion includes at least one groove extending in the length direction.

[0012] In an embodiment of the present invention, at least one of the grooves spans two adjacent chain teeth in the length direction.

[0013] In an embodiment of the present invention, the upper end of the groove provided in one of the pair of chain teeth is aligned in the length direction with the lower end of the chain tooth of the other pair of chain teeth adjacent to the groove in the length direction.

[0014] In an embodiment of this utility model, the mounting hole is formed by notches provided at the ends of a plurality of adjacent chain teeth.

[0015] In an embodiment of the present invention, the size of the last tooth in one of the plurality of teeth of a pair of chain teeth is larger than the size of the other teeth in the chain teeth.

[0016] Based on the above, in the zipper chain of this utility model, the stop includes an outer portion and an inner portion, one of which has a pin, the other has an opening, and at least one has a rib. Furthermore, a portion of the chain teeth has a mounting hole and a groove corresponding to the rib. After the pin is inserted into the opening through the mounting hole and secured, the outer and inner portions are fixed to a portion of the chain teeth, and the rib is embedded in the groove. Thus, the pin, after being inserted into and secured to the opening, is difficult to pull out, making it difficult to separate the outer and inner portions of the stop. Furthermore, the engagement of the rib and the groove prevents the stop from flipping or falling off. Therefore, the zipper chain of this utility model improves the installation effect and structural strength of the stop installed on a zipper chain including the core wire.

Figures 1 to 6B This invention describes the specific structure of a zipper chain 100 according to an embodiment of the present invention, and uses... Figures 7 to 9B The present invention describes the specific structure of the zipper chain 200 according to another embodiment of the present invention, but the present invention is not limited thereto and can be adjusted according to requirements.

[0053] Please refer to Figures 1 to 6BIn one embodiment of this utility model, the zipper chain 100 includes a pair of core wires 110A and 110B, a pair of chain teeth 120A and 120B, and a stop 130. The pair of core wires 110A and 110B extend in the length direction L (corresponding to the vertical direction). The pair of chain teeth 120A and 120B are respectively disposed on the pair of core wires 110A and 110B. The stop 130 is disposed on a portion of the pair of chain teeth 120A and 120B in the engaged state (for example, the end in the length direction L, corresponding to the lower side in the vertical direction). The stop 130 includes an outer portion 132 and an inner portion 134 respectively disposed from the outer side S1 and the inner side S2 of the pair of chain teeth 120A and 120B. One of the outer portion 132 and the inner portion 134 (e.g., the outer portion 132) is provided with a pin portion 132a, and the other of the outer portion 132 and the inner portion 134 (e.g., the inner portion 134) is provided with an opening portion 134a. At least one of the outer portion 132 and the inner portion 134 (both shown here) is provided with a rib portion 136. A portion of a pair of chain teeth 120A, 120B (e.g., the end in the length direction L, corresponding to the lower side in the vertical direction) is provided with a mounting hole 122 for the pin portion 132a to pass through, and a groove portion 124 corresponding to the rib portion 136. The outer portion 132 and the inner portion 134 of the stop 130 are provided on a portion of a pair of chain teeth 120A, 120B after the pin portion 132a is inserted into the opening portion 134a through the mounting hole 122 and reinforced, and at least a portion of the rib portion 136 is embedded in the groove portion 124.

[0054] Specifically, in this embodiment, as Figure 1 and Figure 2 As shown, a pair of chain teeth 120A and 120B are respectively disposed on a pair of core wires 110A and 110B, that is, chain tooth 120A is disposed on core wire 110A and chain tooth 120B is disposed on core wire 110B. The pair of chain teeth 120A and 120B are disposed along the length direction L (equivalent to the vertical direction) on the corresponding pair of core wires 110A and 110B. Thus, when the pair of core wires 110A and 110B are disposed adjacent to each other, the pair of chain teeth 120A and 120B can be interlocked, and the pair of chain teeth 120A and 120B can be opened or closed by sliding a pull head (not shown) on the zipper chain 100. Furthermore, the pair of chain teeth 120A and 120B are located at the ends of the pair of core wires 110A and 110B (at... Figure 1 and Figure 2 The two chains (the lower end) are fitted together and closed, and the stop 130 is provided on a part of the pair of chain teeth 120A, 120B in the fitted state (that is, covering the ends of the pair of chain teeth 120A, 120B).

[0055] Furthermore, in this embodiment, as Figure 3 As shown, the outer portion 132 and inner portion 134 of the stop 130 are generally flat. Here, the pin portion 132a is, for example, a protruding pin structure (e.g., cylindrical) that protrudes from the inner side of the outer portion 132 (the surface facing the inner portion 134) toward the inner portion 134 and has a length greater than the thickness of the flat body of the outer portion 132. The opening portion 134a is, for example, a through-hole structure (e.g., circular hole) that penetrates the opposite sides of the inner portion 134, and the size (e.g., diameter) of the opening portion 134a is larger than the size (e.g., diameter) of the pin portion 132a. Furthermore, a portion of a pair of chain teeth 120A, 120B (i.e., the ends of the pair of chain teeth 120A, 120B where the stop 130 will be mounted) is provided with a mounting hole 122 for the pin portion 132a to pass through. Thus, with the outer portion 132 and the inner portion 134 respectively positioned from the outer side S1 and inner side S2 of a pair of chain teeth 120A and 120B, the pin portion 132a of the outer portion 132 is inserted into the opening 134a of the inner portion 134 through the mounting holes 122 of the chain teeth 120A and 120B (e.g., ...). Figure 2 As shown, the outer portion 132 and the inner portion 134 respectively abut against the outer side S1 and inner side S2 surfaces of a pair of chain teeth 120A and 120B, and can be further secured to a portion of the outer side S1 and inner side S2 of the pair of chain teeth 120A and 120B by reinforcing with the pin portion 132a. However, in other embodiments not shown, the inner portion 134 may have a pin portion 132a and the outer portion 132 may have an opening portion 134a. This utility model does not limit the specific structure of the tool 130, etc., and it can be adjusted according to needs.

[0056] Here, as Figure 2 As shown, the reinforcement refers to fixing the pin portion 132a inserted into the opening 134a, thereby fixing the outer portion 132 and the inner portion 134 to each other. As an example, the length of the pin portion 132a is greater than the sum of the thickness of the pair of chain teeth 120A, 120B and the thickness of the inner portion 134, such that after the pin portion 132a is inserted into the opening 134a through the mounting hole 122, it protrudes from the opening 134a (i.e., forming a protruding portion 132b). Thus, as... Figure 4A and Figure 4BAs shown, after the pin portion 132a is inserted into the opening portion 134a through the mounting hole 122, the protruding portion 132b of the pin portion 132a is pressed by a step such as a stamping process, making the protruding portion 132b of the pin portion 132a flatten and enlarge (i.e., forming a flat portion 132c), and the size (e.g., diameter) of the flat portion 132c is larger than the size (e.g., diameter) of the opening portion 134a. Thus, the flat portion 132c of the pin portion 132a abuts against the surface of the inner surface portion 134 and covers the opening portion 134a, making it difficult for the pin portion 132a to move backward and be pulled out from the opening portion 134a. Therefore, the outer portion 132 and the inner surface portion 134 are difficult to separate after the pin portion 132a is reinforced, allowing the stop 130 to be stably mounted on a pair of chain teeth 120A, 120B. However, this invention does not limit the reinforcement method of the pin portion 132a, etc., which can be adjusted according to requirements.

[0057] Furthermore, in this embodiment, such as Figures 5A to 6B As shown, both the outer portion 132 and the inner portion 134 of the stop 130 are provided with protruding ribs 136. The protruding ribs 136 are, for example, strip-shaped protrusions that are provided on the inner surfaces (facing each other) of the outer portion 132 and the inner portion 134 and protrude in opposite directions. Correspondingly, the outer surface S1 and inner surface S2 of a pair of chain teeth 120A and 120B are each provided with a groove 124. The groove 124 is, for example, a strip-shaped groove corresponding to the protruding ribs 136, provided on the end surfaces of the outer surface S1 and inner surface S2 of a pair of chain teeth 120A and 120B. Thus, the pin 132a is inserted into the opening 134a through the mounting hole 122 (e.g., ...). Figure 2 As shown, with the outer portion 132 and the inner portion 134 respectively abutting against the outer side S1 and inner side S2 surfaces of a pair of chain teeth 120A and 120B, since the grooves 124 of the pair of chain teeth 120A and 120B correspond to the protruding ribs 136 of the stop 130, at least a portion of the protruding ribs 136 is embedded in the grooves 124. However, this utility model does not limit the specific structure and setting position of the protruding ribs 136, which can be adjusted according to requirements.

[0058] With the above configuration, in the zipper chain 100 of this embodiment, the stop 130 includes an outer portion 132 and an inner portion 134. One of them (e.g., the outer portion 132) is provided with a pin portion 132a, the other (e.g., the inner portion 134) is provided with an opening portion 134a, and at least one of them (e.g., both) is provided with a rib portion 136. Furthermore, a portion (e.g., the end) of the chain teeth 120A and 120B is provided with a mounting hole 122 and a groove portion 124 corresponding to the rib portion 136. After the pin portion 132a is inserted into the opening portion 134a through the mounting hole 122 and reinforced, the outer portion 132 and the inner portion 134 are fixed to a portion (e.g., the end) of the chain teeth 120A and 120B, and the rib portion 136 is embedded in the groove portion 124. Thus, the reinforced pin portion 132a inserted into the opening 134a is difficult to pull out from the opening 134a, making it difficult to separate the outer portion 132 and the inner portion 134 of the stop 130. Furthermore, the stop 130 and the chain teeth 120A, 120B are engaged by the rib portion 136 and the groove portion 124, making it difficult for the stop 130 to flip and fall off. Accordingly, the zipper chain 100 can improve the installation effect and structural strength of the stop 130 installed on the zipper chain 100 including the core wires 110A, 110B. However, this invention is not limited thereto and can be adjusted according to requirements.

[0059] Furthermore, in this embodiment, as Figure 4A and Figure 4B As shown, the outer portion 132 and the inner portion 134 of the stop 130 have an opening 134a (i.e., the inner portion 134) with a receiving recess 134b. The opening 134a is formed in the receiving recess 134b, and a part of the reinforced pin portion 132a (e.g., the flat portion 132c formed by pressing the protruding portion 132b) is located in the receiving recess 134b. As an example, the receiving recess 134b is located on the outer side of the inner portion 134 having the opening 134a, corresponding to the protruding portion 132b that protrudes after being inserted into the opening 134a through the mounting hole 122. The size (e.g., diameter) of the receiving recess 134b (e.g., a circular groove) is larger than the size (e.g., diameter) of the opening 134a (e.g., a circular hole) and surrounds the opening 134a. Therefore, the flat portion 132c formed after the reinforcement of the pin portion 132a can be received in the receiving recess 134b without protruding from the outer side of the inner portion 134. However, in other embodiments not shown, the receiving recess 134b may be omitted, allowing the flat portion 132c of the pin portion 132a to protrude from the outer side of the inner portion 134. This invention does not limit the location or presence of the receiving recess 134b; it can be adjusted according to requirements.

[0060] Furthermore, in this embodiment, as Figure 6A and Figure 6B As shown, the mounting holes 122 provided on a pair of chain teeth 120A and 120B are formed by notches provided at the ends of adjacent chain teeth 126A and 126B. As an example, the chain teeth 126A and 126B of each of the chain teeth 120A and 120B are arranged in an alternating pattern and interlock. Specifically, the chain teeth 126A of the chain tooth 120B are located between two adjacent chain teeth 126A of the chain tooth 120A, and at least the upper end of the last chain tooth 126B of the chain tooth 120B is located between the last two adjacent chain teeth 126A of the chain tooth 120A. Furthermore, the opposing ends of the two adjacent chain teeth 126A at the end of the chain tooth 120A are provided with notches, and the upper end of the last chain tooth 126B of the chain tooth 120B adjacent to the aforementioned two adjacent chain teeth 126A is also provided with a notch facing the aforementioned end. Thus, these three opposing notches at the ends of a pair of chain teeth 120A and 120B form a generally circular mounting hole 122 located in the middle of the pair of chain teeth 120A and 120B and through which the pin portion 132a passes. This avoids the reduction in structural strength caused by forming mounting holes 122 on individual chain teeth 126A and 126B. However, this invention does not limit the specific structure and location of the mounting hole 122, which can be adjusted according to requirements.

[0061] Furthermore, in this embodiment, such as Figure 6A and Figure 6BAs shown, in one of a pair of chain tooth rows 120A and 120B (such as chain tooth row 120B on the right), the last chain tooth 126B of chain tooth row 120B is larger than the other chain teeth 126A of chain tooth row 120B. As an example, the chain teeth 126A and 126B of each of chain tooth rows 120A and 120B are arranged in an alternating and interlocking manner. The chain teeth 126A of each of chain tooth rows 120A and 120B are approximately the same size, and the last chain tooth 126B of chain tooth row 120B is larger. The teeth 126A of the chain tooth row 120B are located between two adjacent teeth 126A of the chain tooth row 120A, and the upper end of the last tooth 126B of the chain tooth row 120B is located between two adjacent last teeth 126A of the chain tooth row 120A, while the lower end is aligned with the lower end of the last tooth 126A of the chain tooth row 120A. Thus, the last tooth 126B of the chain tooth row 120B is extended to span the upper and lower sides of the last tooth 126A of the chain tooth row 120A. That is, the size of the last tooth 126B of the chain tooth row 120B is larger than the size of the other teeth 126A of the chain tooth row 120B (equivalent to the size of the teeth 126A of the chain tooth row 120A), which further improves the structural strength of the tooth 126B. However, this invention does not limit the specific structure and size of the teeth 126A and 126B, which can be adjusted according to requirements.

[0062] Therefore, in this embodiment, as Figure 5A and Figure 5B As shown, the rib portion 136 includes a plurality of first ribs 136a extending in the width direction W (i.e., the left-right direction in the figures), and as... Figure 6A and Figure 6BAs shown, the groove portion 124 includes at least one groove 124a extending in the width direction W (i.e., the left-right direction in the figure). For example, the outer portion 132 and the inner portion 134 of the stop 130 each have three first protruding ribs 136a arranged at equal intervals on their inner surfaces on the left and right sides respectively (or only one of the outer portion 132 and the inner portion 134 or one of the left and right sides of the stop 130 may be provided). Correspondingly, two grooves 124a are provided on the outer surface S1 and the inner surface S2 of two adjacent teeth 126A at the end of the chain tooth row 120A, and two grooves 124a are provided on the outer surface S1 and the inner surface S2 of the upper end and the lower end of the chain tooth 126B at the end of the chain tooth row 120B (or only one of the outer surface S1 and the inner surface S2 or one of the chain tooth rows 120A and 120B may be provided). Preferably, the rib portion 136 further includes a plurality of second ribs 136b extending in the length direction L (i.e., the front-rear direction in the figures) and connecting the plurality of first ribs 136a. For example, the left and right pairs of edges of the inner surfaces of the outer portion 132 and the inner portion 134 of the stop 130 are provided with second ribs 136b (or only one of the outer portion 132 and the inner portion 134 or one of the left and right sides of the stop 130 may be provided with second ribs 136b).

[0063] With the above configuration, in the zipper chain 100 of this embodiment, regardless of whether the first rib 136a and the second rib 136b are located on the outer portion 132 and the inner portion 134, or on either the left or right side of the stop 130, and whether the groove 124a is located on the outer side S1 and the inner side S2, or on either of the pair of chain teeth 120A and 120B, when the stop 130 is installed on the pair of chain teeth 120A and 120B, at least one of the plurality of first ribs 136a is embedded in at least one groove 124a, and at least another of the plurality of first ribs 136a is embedded in the gap 128 between two adjacent chain teeth 126A or two adjacent chain teeth 126A and 126B in the chain teeth 120A and 120B. For example, the first and third first protruding ribs 136a on one of the left and right sides are respectively embedded in the two grooves 124a on the chain tooth row 120A, and the second first protruding rib 136a is respectively embedded in the gap 128 on the chain tooth row 120A. Similarly, the first first protruding rib 136a on the other left and right sides is respectively embedded in the gap 128 on the chain tooth row 120B, and the second and third first protruding ribs 136a are respectively embedded in the two grooves 124a on the chain tooth row 120B. Furthermore, the plurality of second protruding ribs 136b act as outer walls and abut against the outer surfaces of opposite sides of a pair of chain tooth rows 120A and 120B in the width direction W (i.e., the left-right direction in the figures). Figure 1(As shown). Thus, the stop 130 and the chain teeth 120A and 120B can prevent the stop 130 from flipping and falling off through the engagement of the first rib 136a and the groove 124a, and through the engagement of the first rib 136a and the gap 128. Furthermore, the structural strength can be improved by the engagement of the first rib 136a and the second rib 136b with different extension directions. However, this utility model does not limit the specific structure of the rib portion 136 and the groove portion 124 (i.e., the specific structure, setting position, and whether or not the first rib 136a, the second rib 136b, and the groove 124a are provided), which can be adjusted according to requirements.

[0064] Please refer to Figures 7 to 9B In another embodiment of this utility model, the zipper chain 200 includes a pair of core wires 210A and 210B, a pair of chain teeth 220A and 220B (with mounting holes 222 and grooves 224), and a stop 230 (including an outer portion 232 and an inner portion 234, and with a pin portion 232a, an opening portion 234a, and a rib portion 236, etc.). Furthermore, after the pin portion 232a is inserted into the opening portion 234a through the mounting holes 222 of the chain teeth 220A and 220B and reinforced (for example, using the aforementioned method for...), the outer portion 232 and the inner portion 234 of the stop 230 are... Figure 2 , Figure 4A and Figure 4BThe reinforcement method described herein (reinforcing the pin portion 232a after insertion into the opening 234a) is provided on a portion (e.g., the end) of a pair of chain teeth 220A, 220B, and at least a portion of the convex rib portion 236 is embedded in the recess portion 224. With this arrangement, the reinforced pin portion 232a inserted into the opening 234a is difficult to pull out of the opening 234a, thus making it difficult for the outer portion 232 of the stop 230 to separate from the inner portion 234. Furthermore, the stop 230 is difficult to flip and fall off because of the engagement of the convex rib portion 236 and the recess portion 224 with the chain teeth 220A, 220B. Accordingly, the zipper chain 200 can improve the installation effect and structural strength of the stop 230 installed on the zipper chain 200 including the core wires 210A, 210B. For details regarding the specific structure of the pair of core threads 210A and 210B, the pair of chain teeth 220A and 220B, and the stop 230 of the zipper chain 200, please refer to the aforementioned description of the specific structure of the zipper chain 100. Furthermore, the inclusion or absence of the receiving recess 134b, the method of forming the mounting hole 122, and the size of the chain teeth 126B in the aforementioned zipper chain 100 can also be applied to the zipper chain 200 as needed. Therefore, the main difference between the zipper chain 200 and the aforementioned zipper chain 100 is that the grooves 224 of the chain teeth 220A and 220B and the ribs 236 of the stop 230 in the zipper chain 200 are different from the grooves 124 of the chain teeth 120A and 120B and the ribs 136 of the stop 130 in the aforementioned zipper chain 100.

[0065] In detail, in this embodiment, such as Figure 8A and Figure 8B As shown, the rib portion 236 includes at least one rib 236a extending in the length direction L (i.e., the up-down direction in the figures), and as... Figure 9A and Figure 9BAs shown, the groove portion 224 includes at least one groove 224a extending in the length direction L (i.e., the up-down direction in the figure). For example, the outer portion 232 and the inner portion 234 of the stop 230 each have a pair of protruding ribs 236a on their inner sides, and the size (length) of each pair of protruding ribs 236a exceeds the size of the pin portion 232a and the size of the opening portion 234a (or only one of the outer portion 232 and the inner portion 234 or one of the left and right sides of the stop 230 may be provided). Correspondingly, a groove 224a is provided on the outer surface S1 and inner surface S2 of two adjacent teeth 226A at the end of the chain tooth row 220A, and a groove 224a is provided on the outer surface S1 and inner surface S2 of the teeth 226B at the end of the chain tooth row 220B (or only one of the outer surface S1 and inner surface S2 or one of the chain tooth rows 220A and 220B may be provided). Preferably, at least one groove 224a (e.g., a groove 224a disposed on the side of the tooth row 220A) spans two adjacent teeth 126A in the length direction L (i.e., the vertical direction in the figures), and the upper end of the groove 224a of one of the tooth rows 220A, 220B (e.g., tooth row 220A) in the length direction L (corresponding to the lower edge of the gap 128 of tooth row 220A) is aligned in the length direction L with the lower end of the tooth 226A of the other tooth row 220B (e.g., tooth row 220B) adjacent to the groove 224a in the length direction L (corresponding to the upper edge of the gap 128 of tooth row 220B). Figure 9A and Figure 9B (As shown by the dashed line in the image).

[0066] With the above configuration, in the zipper chain 200 of this embodiment, regardless of whether the ribs 236a are located on the outer portion 232 or the inner portion 234, or on either the left or right side of the stop 230, and whether the grooves 224a are located on the outer side S1 or the inner side S2, or on either of the pair of chain teeth 220A, 220B, when the stop 230 is installed on the pair of chain teeth 220A, 220B, at least one of the plurality of ribs 236a is embedded in at least one groove 224a. For example, the left and right pair of ribs 236a are embedded in the left and right pair of grooves 224a. In this way, the stop 230 and the chain teeth 220A, 220B can make the stop 230 difficult to flip and fall off through the engagement of the ribs 236a of the rib portion 236 and the grooves 224a of the groove portion 224, and can provide a good engagement effect in the larger length direction L, thereby improving the structural strength. Here, since this embodiment does not provide the aforementioned multiple second ribs 136b serving as the outer sidewall (as shown in the example), Figure 1As shown), the stop 230 mounted on a pair of chain teeth 220A, 220B exposes the outer surfaces of the pair of chain teeth 220A, 220B on opposite sides in the width direction W (i.e., the left-right direction in the figure) between the outer portion 232 and the inner portion 234. Figure 7 As shown), however, this utility model does not exclude the combined application of the aforementioned convex rib 136 and the convex rib 236 of this embodiment (the same applies to the aforementioned groove 224 and the groove 124 of this embodiment). However, this utility model does not limit the specific structure of the convex rib 236 and the groove 224 (i.e., the specific structure, setting position, and whether or not to set the convex rib 236a and the groove 224a, etc.), which can be adjusted according to requirements.

[0067] In summary, in the zipper chain of this utility model, the stop includes an outer portion and an inner portion, one of which has a pin, the other has an opening, and at least one has a rib. Furthermore, a portion of the chain teeth has a mounting hole and a groove corresponding to the rib. After the pin is inserted into the opening through the mounting hole and secured, the outer and inner portions are fixed to a portion of the chain teeth, and the rib is embedded in the groove. Thus, the pin, after being inserted into and secured to the opening, is difficult to pull out, making it difficult to separate the outer and inner portions of the stop. Furthermore, the stop and the chain teeth are difficult to flip and fall off due to the engagement of the rib and the groove. Preferably, the mounting hole is formed by a notch at the end of adjacent chain teeth in the chain teeth, and the size of the last chain tooth of one of the chain teeth is increased, thereby maintaining the local structural strength of the chain teeth near the mounting hole while providing the mounting hole. Accordingly, the zipper chain of this utility model can improve the installation effect and structural strength of the stop installed on the zipper chain including the core wire.
