Description

Technical Field

[0001] The utility model relates to the technology in the field of fasteners, and in particular to a slider for a fastener and a fastener using the slider for a fastener. Background Art

[0002] A common zipper generally includes a zipper chain (fastener chain) composed of a pair of left and right fastener tapes and an element column installed on the zipper tape, and a zipper slider installed on the zipper chain and opening or closing the element by sliding, and a tab pull or the like may also be installed on the zipper slider to drive the sliding of the zipper slider. Among them, the end of one side of the pair of left and right zipper tapes may be provided with a separable pin and a retainer pin and other opening parts (opening parts). As an example, in a double-open-end zipper (i.e., a zipper composed of a pair of zipper sliders installed on the zipper chain, and the zipper chain can be opened from two opposite ends of the zipper chain), by sliding the zipper slider in a direction away from the end of the zipper chain, the pair of left and right element columns can be separated from each other and the zipper chain can be opened from the end. Furthermore, by sliding the slider toward the end of the zipper chain, the left and right pairs of fastener elements can be meshed with each other to close the zipper chain toward the end, and the insert rod and the seat rod provided at the end can be butted against each other.

[0003] Furthermore, in the prior art, the end of the insert rod facing the chain tooth row is provided with a half-chain tooth portion, that is, the end of the insert rod is formed with a protruding structure having a half shape of a single chain tooth on the chain tooth row, which is used to engage with one of the chain teeth of the opposite chain tooth row. However, when the zipper slider slides with the front end side (that is, the end where the connecting column is located) toward the direction close to the end of the zipper chain (that is, toward the insert rod), since the parts of the zipper chain corresponding to the insert rod are not closed and separated from each other, the opened zipper tape flips outward, causing the end of the insert rod provided with the half-chain tooth portion to flip outward and not align with the chain tooth channel of the zipper slider (for example, the half-chain tooth portion formed at the inner part of the end flips outward to a position higher than the lower surface of the upper wing plate of the zipper slider). In this case, the half-chain tooth portion of the insert rod may be stuck by the upper wing plate of the zipper slider when passing through the zipper slider, making it difficult for the zipper slider to continue sliding toward the direction close to the end. If the zipper slider is forced to continue sliding, the half-chain tooth portion of the plug rod and the nearby chain teeth may be damaged. Therefore, it is necessary to improve the structure of the zipper slider to guide the plug rod when the zipper slider passes through the plug rod turned outward, so as to improve the situation that the zipper slider is stuck by the half-chain tooth portion of the plug rod during the sliding process, thereby improving the sliding smoothness of the zipper slider and avoiding damage to the plug rod. Utility Model Content

[0004] The utility model provides a zipper pull head and a zipper, which can improve the sliding smoothness of the zipper pull head and avoid damage to an insertion rod.

[0005] The utility model provides a zipper slider, which is suitable for being installed on a zipper chain and passing through an insert rod installed by the zipper chain by sliding, and comprises: an upper wing plate and a lower wing plate, which are arranged opposite to each other with a gap in the up and down directions; a connecting column, which connects the front end sides of the upper wing plate and the lower wing plate; and at least one guide protrusion, which is arranged on the front end side of the upper wing plate and is located on one side edge of the connecting column, wherein the lower surface of the guide protrusion facing the lower wing plate is formed as a plane, and is horizontally formed from the lower surface of the upper wing plate corresponding to the chain tooth channel, and the guide protrusion has an inclined surface that gradually widens from the front end to the end, and the width of the inclined surface is greater than the difference between the length of the diagonal line of the end of the insert rod provided with a half-chain tooth portion and the thickness of the half-chain tooth portion.

[0006] In an embodiment of the present invention, a protrusion amount of the guide protrusion in the length direction of the zipper slider is greater than a length of the half-chain element portion provided on the insert rod.

[0007] In an embodiment of the present invention, the guide protrusion has a first guide surface which is formed on a lower side of the front end and is inclined in the up-down direction.

[0008] In an embodiment of the present invention, the zipper slider further comprises: a guide recess, which is arranged at the front end side of the upper wing plate and between the connecting column and the guide protrusion, and the inclined surface is connected to the guide recess.

[0009] In an embodiment of the present invention, the guide recess has a second guide surface formed at a lower side of the distal end and inclined in the up-down direction, and a width of the second guide surface gradually increases from the upper side toward the lower side.

[0010] In an embodiment of the present invention, there is no step difference between the lower surface of the guide protrusion facing the lower wing plate and the lower surface of the upper wing plate corresponding to the coupling element channel.

[0011] The utility model also provides a zipper, which includes: a zipper chain, including a zipper tape, a chain tooth row installed on the zipper tape, and an insert rod installed at the end of the chain tooth row; and a zipper slider installed on the zipper chain and suitable for sliding through the insert rod installed on the zipper chain.

[0012] In an embodiment of the present invention, the zipper tape includes a flexible portion having softness.

[0013] Based on the above, in the zipper slider and zipper of the utility model, at least one guide protrusion is arranged on the front end side of the upper wing plate and is located on one side of the connecting column, wherein the lower surface of the guide protrusion facing the lower wing plate is formed into a plane, and is formed horizontally from the lower surface of the upper wing plate corresponding to the chain tooth channel, and the guide protrusion has an inclined surface that gradually widens from the front end to the end, and the width of the inclined surface is greater than the difference between the length of the diagonal line of the end of the insert rod provided with the half chain tooth portion and the thickness of the half chain tooth portion. Through the above arrangement, when the zipper slider is installed on the zipper chain and the insert rod installed by the zipper chain is passed through by sliding, the guide protrusion can contact the insert rod through the inclined surface and guide the insert rod flipped outward to the positive direction while sliding, so that the insert rod can smoothly enter the chain tooth channel of the zipper slider from the lower surface of the guide protrusion formed into a plane, and the half chain tooth portion of the insert rod will not be stuck by the upper wing plate. Accordingly, the zipper slider and the zipper of the utility model can improve the sliding smoothness of the zipper slider and avoid damage to the insert rod.

[0014] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below and described in detail with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Figure 1 1 is a three-dimensional schematic diagram of a zipper equipped with a zipper slider according to an embodiment of the utility model. Figure 2 yes Figure 1 A schematic plan view of a partial structure of a zipper with a zipper slider installed, Figure 3 yes Figure 2 The schematic diagram of a partial enlargement of a zipper with a zipper slider installed in area R is shown. Figure 4 yes Figure 1 The partial three-dimensional schematic diagram of the zipper slider around the guide protrusion is shown. Figure 5 yes Figure 1 A three-dimensional schematic diagram of a zipper insert used in the embodiment shown, Figure 6 yes Figure 5 The schematic plan view of the end of the plunger with the half-chain tooth portion is shown in FIG. Figures 1 to 6 The specific structure of the zipper slider 100 and the zipper 50 equipped with the zipper slider 100 according to the embodiment of the present invention is described, but this is only one example, and the present invention is not limited thereto and can be adjusted according to needs.

[0055] Please refer to Figure 1In this embodiment, the zipper 50 includes a zipper chain 60 and a zipper slider 100. The zipper chain 60 includes a zipper tape 62, a chain element row 64 installed on the zipper tape 62, and an insert rod 66 and a seat rod 68 installed at the ends of the chain element row 64. The left and right pairs of zipper tapes 62 extend in the length direction L of the zipper chain 60, the left and right pairs of chain element rows 64 are respectively arranged at the inner side edges of the left and right pairs of zipper tapes 62, and the ends of the left and right pairs of chain element rows 64 are correspondingly provided with an insert rod 66 and a seat rod 68. The zipper slider 100 is installed on the zipper chain 60, and is suitable for sliding through the left and right pairs of chain element rows 64 installed on the zipper chain 60, and the insert rod 66 and the seat rod 68 at the ends. The left and right direction corresponds to the width direction W of the zipper chain 60 and the zipper slider 100 of the zipper 50. Furthermore, a pull tab 70 or the like may be installed on the zipper slider 100 to drive the sliding of the zipper slider 100 , but the present invention is not limited thereto and may be adjusted according to requirements.

[0056] For example, in a double-open-end zipper as the zipper 50 (i.e., a zipper composed of a pair of zipper sliders 100 mounted on a zipper chain 60, and the zipper chain 60 can be opened from opposite ends of the zipper chain 60), the zipper slider 100 is directed away from the end of the zipper chain 60 (for example, Figure 1 The left and right pair of fastener element rows 64 can be separated from each other and the zipper chain 60 can be opened from the end. And, by moving the zipper slider 100 toward the end of the zipper chain 60 (for example, Figure 1 The slide of the left and right pair of chain element rows 64 can mesh with each other to close the zipper chain 60 to the end. Furthermore, the zipper slider 100 can slide through the insert rod 66 and the seat rod 68 installed on the zipper chain 60, and further make the insert rod 66 and the seat rod 68 provided at the end dock with each other. Figure 1 The state in which the element rows 64 of the slide fastener chain 60 are engaged with each other but the insert rod 66 and the seat rod 68 provided at the ends are not yet in contact with each other is shown.

[0057] Furthermore, in this embodiment, if Figures 1 to 3 As shown, the end E of the plunger 66 facing the chain element row 64 (ie, Figure 1 The lower end E of the insert rod 66 is provided with a half-tooth portion 66a, that is, the end E of the insert rod 66 is formed with a protruding structure having a half shape of a single tooth on the tooth row 64, which is used to engage with one of the teeth (at the bottom of the tooth row 64) of the opposite tooth row 64. Figure 1 However, when the zipper slider 100 is engaged with the inner part of the zipper slider 100 and not shown, the front end side E1 (i.e., the side corresponding to the connecting column 130 described later in the length direction L) toward the direction close to the end of the zipper chain 60 (for example, Figure 1When the zipper chain 60 slides toward the insertion rod 66, the portion corresponding to the insertion rod 66 is not closed and separated from each other, and the opened zipper tape 62 is turned outward (such as Figure 1 As shown in FIG. 1 ), the end E of the insert rod 66 provided with the half-chain tooth portion 66a is turned outward and not aligned with the chain tooth channel of the zipper slider 100 (for example, the half-chain tooth portion 66a formed on the inner side of the end E is turned outward to a position higher than the lower surface of the upper wing plate 110 of the zipper slider 100). Therefore, in order to prevent the half-chain tooth portion 66a of the insert rod 66 from being caught by the upper wing plate 110 of the zipper slider 100 when passing through the zipper slider 100, it is necessary to guide the insert rod 66 when the zipper slider 100 passes through the turned-out insert rod 66, thereby improving the sliding smoothness of the zipper slider 100 and avoiding damage to the insert rod 66.

[0058] Specifically, in this embodiment, if Figure 1 As shown, the zipper slider 100 is suitable for being installed on the zipper chain 60 and passing through the insert rod 66 installed on the zipper chain 60 by sliding. Among them, the zipper slider 100 includes an upper wing plate 110, a lower wing plate 120, a connecting column 130, and a guide protrusion 140. The upper wing plate 110 and the lower wing plate 120 are arranged opposite to each other with a gap in the up and down direction (that is, the thickness direction T). The connecting column 130 connects the front end side E1 of the upper wing plate 110 and the lower wing plate 120 (that is, one side in the length direction L), and the rear end side E2 of the upper wing plate 110 and the lower wing plate 120 (that is, the other side in the length direction L) is open to the outside. In addition, the outer edges of the upper wing plate 110 and / or the lower wing plate 120 are also provided with a pair of left and right flanges 150 ( Figure 1 The right side is shown as an example), and a gap is formed on the outer edge for the zipper tape 62 to pass through, and the fastener element row 64 (at Figure 1 Thus, a pair of left and right chain element passages 160 located on opposite sides of the connecting column 130 are formed between the upper wing plate 110 and the lower wing plate 120 and between the left and right flanges 150, so that the chain element row 64 provided on the zipper chain 60 and the insert rod 66 and the seat rod 68 located at the end of the chain element row 64 can pass through.

[0059] In addition, in this embodiment, Figures 1 to 3As shown, the guide protrusion 140 is arranged on the front end side E1 of the upper wing plate 110 and is located on one side of the connecting column 130. Here, the zipper slider 100 is provided with a pair of guide protrusions 140 symmetrical along the center line C of the upper wing plate 110 at the front end side E1 of the upper wing plate 110 and on the opposite sides of the connecting column 130, and the guide protrusion 140 on the right side corresponds to the insert rod 66 provided at the end of the zipper tape 62 on the right side. In this way, the guide protrusion 140 on the left side can be selected or omitted according to needs. Further, in the case where the zipper slider 100 is provided with a pair of guide protrusions 140 on the upper wing plate 110 (that is, this embodiment), the zipper slider 100 can be used as a universal zipper slider, and is not limited to whether the insert rod 66 is provided on the right or left side, and can be guided by one of the guide protrusions 140. Alternatively, in other embodiments not shown, the zipper slider may also be provided with a guide protrusion only on one side of the upper wing plate to serve as a dedicated zipper slider to guide the insert rod provided on a specific side. The present invention is not limited to this and can be adjusted according to needs.

[0060] Here, if Figure 2 and Figure 3 As shown, the guide protrusion 140 is protruding in the length direction L of the zipper slider 100. That is, the guide protrusion 140 is configured as a protruding structure extending from the edge of the front end side E1 of the upper wing plate 110 (i.e., the side corresponding to the connecting column 130 in the length direction L) to the front side. In this way, when the zipper slider 100 is directed from the front end side E1 toward the direction close to the end of the zipper chain 60 (for example, Figure 1 When the guide protrusion 140 slides toward the plunger 66 (the upper side in FIG. 1 ), the guide protrusion 140 protrudes toward the plunger 66. Figure 4 As shown, the lower surface S1 of the guide protrusion 140 facing the lower wing plate 120 is formed as a plane, and is horizontally formed from the lower surface S2 of the upper wing plate 110 corresponding to the fastener element passage 160. Preferably, there is no step difference between the lower surface S1 of the guide protrusion 140 facing the lower wing plate 120 and the lower surface S2 of the upper wing plate 110 corresponding to the fastener element passage 160. Figure 2 and Figure 3 As shown, the guide protrusion 140 has an inclined surface 142 that gradually widens from the front end (i.e., the end corresponding to the front end side E1) to the end (i.e., the end close to the upper wing plate 110), and the width W1 of the inclined surface 142 (in Figure 3 The length L1 of the diagonal line of the end E of the plunger 66 provided with the half-chain tooth portion 66a is greater than that of the plunger 66 (in Figure 6 The thickness T1 of the half-element portion 66a (in Figure 6 The difference between the marked).

[0061] Through the above settings, in this embodiment, if Figures 1 to 3As shown, since the guide protrusion 140 protrudes further forward from the edge of the front end side E1 of the upper wing plate 110, the zipper slider 100 is oriented in a direction close to the insert rod 66 with the front end side E1 (ie, Figure 1 When the guide protrusion 140 slides upward, the guide protrusion 140 contacts the plunger 66. Here, since the width W1 of the inclined surface 142 of the guide protrusion 140 is set as described above, the half-chain tooth portion 66a corresponds to at least a portion of the inclined surface 142 (such as the upper side) when the plunger 66 is turned outward. Figure 1 As the zipper slider 100 continues to slide toward the direction close to the insert rod 66, the half-tooth portion 66a slides along the inclined surface 142, causing the insert rod 66 to reverse to the positive direction (as shown in the figure) under the guidance of the guide protrusion 140. Figure 2 and Figure 3 In this way, when the zipper slider 100 is installed on the zipper chain 60 and the insert rod 66 installed on the zipper chain 60 is passed through by sliding, the guide protrusion 140 can contact the insert rod 66 through the inclined surface 142 and guide the insert rod 66 flipped outward to the positive direction while sliding (that is, the half-chain tooth portion 66a is reversely flipped to a position below the lower surface of the upper wing plate 110 and corresponding to the chain tooth channel 160), so that the insert rod 66 is pulled out from the lower surface of the guide protrusion 140 formed as a plane (at Figure 4 ) can smoothly enter the tooth channel 160 of the zipper slider 100 without the half tooth portion 66a of the insert rod 66 being caught by the upper wing plate 110. Accordingly, the zipper slider 100 and the zipper 50 can improve the sliding smoothness of the zipper slider 100 and avoid damage to the insert rod 66.

[0062] As an example, in this embodiment, if Figure 3As shown, the protrusion amount of the guide protrusion 140 in the length direction L of the zipper slider 100 (i.e., the length L2 of the guide protrusion 140) is greater than the length L3 of the half-tooth portion 66a provided on the insert rod 66. Therefore, during the sliding process of the zipper slider 100, the half-tooth portion 66a of the insert rod 66 first contacts the front end vertex of the guide protrusion 140 (i.e., the most protruding point as the starting point of the inclined surface 142). In this way, the zipper slider 100 can guide the end E of the insert rod 66 that is turned outward with the inclined surface 142 of a longer length, so that the half-tooth portion 66a of the insert rod 66 is reversely turned along the inclined surface 142 to the positive direction (i.e., corresponding to the tooth channel 160). However, in other embodiments not shown, the protrusion amount of the guide protrusion 140 in the length direction L of the zipper slider 100 can also be set to be smaller. Nevertheless, since the width W1 of the inclined surface 142 of the guide protrusion 140 is set as described above, the half-tooth portion 66a can still correspond to at least a portion of the inclined surface 142 when the insert rod 66 is turned outward, so that the half-tooth portion 66a is turned back to the positive direction along the inclined surface 142, and the half-tooth portion 66a smoothly enters the tooth channel 160 from the lower surface of the guide protrusion 140 formed into a plane after the insert rod 66 is turned back to the positive direction. The utility model is not limited to this, and it can be adjusted according to needs.

[0063] In addition, in this embodiment, Figures 1 to 3 As shown, the zipper slider 100 also includes a guide recess 170. The guide recess 170 is disposed on the front end side E1 of the upper wing plate 110 and is located between the connecting column 130 and the guide protrusion 140, and the inclined surface 142 connects the guide recess 170. In the case where the zipper slider 100 is provided with a pair of guide protrusions 140 on the upper wing plate 110 (i.e., this embodiment), the zipper slider 100 is also provided with a pair of guide recesses 170 on the upper wing plate 110, and the pair of guide recesses 170 are symmetrical along the center line C of the upper wing plate 110. Similarly, in other embodiments not shown, if only one guide protrusion 140 is provided, only one guide recess 170 is provided. The present invention is not limited to this, and it can be adjusted according to needs.

[0064] Furthermore, in this embodiment, if Figures 1 to 3 As shown in FIG. 1 , the inclined surface 142 serves as the inner side of the guide protrusion 140 and also serves as the outer side of the guide recess 170. In this way, the guide recess 170 is configured as a concave structure that gradually narrows from the front end (i.e., the end corresponding to the front end side E1) to the end (i.e., the end close to the upper wing plate 110). Here, the width W2 of the front side of the guide recess 170 (at Figure 3 The length L1 of the diagonal line of the end E of the plunger 66 provided with the half-chain tooth portion 66a is preferably greater than that of the half-chain tooth portion 66a. Figure 6The width W3 of the rear side of the guide recess 170 (in Figure 3 The thickness T1 of the end E of the plunger 66 is preferably greater than that of the plunger 66 (in Figure 6 ). The width W2 of the front side of the guide recess 170 is the width of the guide recess 170 corresponding to the vertex of the guide protrusion 140 in the width direction W, and the width W3 of the rear side of the guide recess 170 is the width of the guide recess 170 corresponding to the distance L3 from the vertex of the guide protrusion 140 to the rear side in the width direction W. Thus, the width W1 (at the outer side) of the inclined surface 142 of the guide recess 170 is Figure 3 Marking) is equivalent to the difference between the width W2 on the front side and the width W3 on the rear side of the guide recess 170, so it is preferred to set the width W1 of the inclined surface 142 to be larger than the difference between the length L1 of the diagonal of the end E of the insert 66 where the half-chain tooth portion 66a is provided and the thickness T1 of the half-chain tooth portion 66a.

[0065] Furthermore, in this embodiment, if Figures 1 to 3 As shown, the front end side E1 of the upper wing plate 110 is formed with a columnar portion 112 corresponding to the shape of the front end side and the left and right sides of the connecting column 130, and the side edge of the front end side E1 of the columnar portion 112 is more protruding to the front side than the side edge of the front end side E1 of the guiding protrusion 140. Thus, a guiding recess 170 is formed correspondingly between the protruding columnar portion 112 and the guiding protrusion 140. The columnar portion 112 is designed based on the specifications of the zipper slider 100, for example, to reduce the contact area between the chain element row 64 and the like that enters the chain element channel 160 through the connecting column 130 and the upper wing plate 110, but it is not limited to this. In other embodiments not shown, the columnar portion 112 corresponding to the connecting column 130 may not be provided on the upper wing plate 110, so that the guiding protrusion 140 is protruded in the length direction L based on the edge of the front end side E1 of the upper wing plate 110, and the provision of the guiding recess 170 is omitted. The present invention does not limit the specific structure of the guiding recess 170 , and whether or not to set it, and it can be adjusted according to needs.

[0066] As an example, in this embodiment, if Figure 4As shown, the guide protrusion 140 has a first guide surface 144 formed on the lower side of the front end (i.e., corresponding to the front end side E1) and inclined in the up-down direction (i.e., thickness direction T). The first guide surface 144 can be a rounded chamfer formed on the front end of the guide protrusion 140. In this way, in the process of the zipper slider 100 sliding with the front end side E1 toward the direction close to the insert rod 66, the guide protrusion 140 can press the insert rod 66 with the first guide surface 144 formed on the lower side of the front end, so that the insert rod 66 flipped outward is pressed and slides along the inclined surface 142 and flips back to the positive direction (i.e., corresponding to the chain tooth channel 160). In addition, the guide recess 170 has a second guide surface 172 formed on the lower side of the end (i.e., the recessed part) and inclined in the up-down direction (i.e., thickness direction T), and the width of the second guide surface 172 gradually increases from the upper side to the lower side, that is, the width W4 of the lower side is greater than the width W5 of the upper side (in Figure 4 Thus, when the zipper slider 100 slides with the front end side E1 toward the direction close to the insert rod 66, the half-chain tooth portion 66a that slides along the inclined surface 142 and is guided to the positive direction can smoothly enter the chain tooth channel 160 between the upper wing plate 110 and the lower wing plate 120 from the upper side to the lower side through the second guide surface 172. However, the present invention does not limit the specific structure of the first guide surface 144 and the second guide surface 172, and whether or not to set them, which can be adjusted according to needs.

[0067] In addition, in this embodiment, Figure 1 As shown, the zipper slider 100 is suitable for being installed on a zipper chain 60 to form a zipper 50. The zipper tape 62 provided in the zipper chain 60 includes a flexible portion having softness. Preferably, the entire zipper tape 62 is made of a flexible material, so that the entire zipper tape 62 has softness. Here, since the width W1 of the inclined surface 142 of the guide protrusion 140 provided in the zipper slider 100 is set as described above, even if the zipper chain 60 made of a zipper tape 62 having softness makes the phenomenon of the insert rod 66 flipping outward more obvious, the guide protrusion 140 can contact the insert rod 66 through the inclined surface 142 and guide the insert rod 66 flipped outward to the positive direction while sliding, so that the insert rod 66 is formed from the lower surface of the guide protrusion 140 (at the bottom surface) formed as a plane. Figure 4) can smoothly enter the chain tooth channel 160 of the zipper pull head 100 for zipper. Therefore, a zipper tape 62 that is more than twice as soft as a general zipper tape can be used to make the zipper chain 60. The softness is the degree to which the zipper tape can bend or bend by compression, which can be obtained by using a tensile testing machine to compress the zipper chain or zipper tape forming a ring to a certain length, and measuring the maximum stress at this time (but not limited to this). In this way, the zipper pull head 100 can be used with the zipper chain 60 made of the zipper tape 62 that is more than twice as soft as a general zipper tape, thereby improving the applicability of the zipper 50 (for example, the zipper 50 is applied to soft fabrics). However, the utility model does not limit the use of the zipper pull head 100 (that is, it does not exclude the application to the zipper chain made of general zipper tapes), and it can be adjusted according to needs.

[0068] In summary, in the zipper slider and zipper of the utility model, at least one guide protrusion is arranged on the front end side of the upper wing plate and is located on one side of the connecting column, wherein the lower surface of the guide protrusion facing the lower wing plate is formed as a plane, and is formed horizontally from the lower surface of the upper wing plate corresponding to the chain tooth channel, and the guide protrusion has an inclined surface that gradually widens from the front end to the end, and the width of the inclined surface is greater than the difference between the length of the diagonal of the end of the insert rod provided with the half chain tooth portion and the thickness of the half chain tooth portion. Preferably, the protrusion of the guide protrusion in the length direction is greater than the length of the half chain tooth portion provided by the insert rod. Through the above arrangement, when the zipper slider is installed on the zipper chain and the insert rod installed by the zipper chain is passed through by sliding, the guide protrusion can contact the insert rod through the inclined surface and guide the insert rod flipped outward to the positive direction while sliding, so that the insert rod can smoothly enter the chain tooth channel of the zipper slider from the lower surface of the guide protrusion formed as a plane, and the half chain tooth portion of the insert rod will not be stuck by the upper wing plate. Accordingly, the zipper slider and the zipper of the utility model can improve the sliding smoothness of the zipper slider and avoid damage to the insert rod.
