Description

Technical Field

[0001] The present invention relates to the technology of the zipper field, and in particular to a slider. Background Art

[0002] A common zipper usually includes a pair of zipper chains (fastener chains) composed of a strip-shaped zipper tape (fastener tape) and a plurality of chain elements (element) arranged on the zipper tape, and a slider installed on the zipper chain to open or close the chain elements by sliding, and a tab pull can also be set on the slider according to needs. In addition, a pair of sliders arranged opposite to each other can be installed on the zipper chain to form a two-way separator. The two-way separator means that the sliders installed in groups on the zipper chain and arranged opposite to each other can open or close the chain elements from the opposite sides of the zipper chain by sliding, thereby opening or closing at least one of the opposite sides of the zipper chain.

[0003] Furthermore, in the prior art, the zipper chain is also provided with a separable pin and a retainer pin. The separable pin and the retainer pin are respectively arranged on a pair of zipper tapes and are located at the ends of the arrangement positions of the chain teeth. When the slider moves upward to open the lower end side of the zipper chain, the separable pin and the retainer pin provided at the end of the zipper tape are separated from each other. Correspondingly, when the slider moves downward to close the lower end side of the zipper chain, the separable pin and the retainer pin provided at the end of the zipper tape approach each other and move to the inside of the slider to engage with each other (for example, the separable pin is inserted into the retainer pin). Among them, a fixing groove is provided inside the slider for the retainer pin provided at the end of the zipper tape to pass through and fix the retainer pin inside the slider. In order to realize the applicability of the slider, fixing grooves are usually provided on opposite sides of the guide column of the slider to facilitate the zipper chain with the separable pin and the retainer pin provided on different sides. At this time, the separable pin also corresponds to the fixing groove on one side. Therefore, when the slider moves downward, if the separated insertion rod and the seat rod flip outward to form an "eight" shape, the lower outer corner or the upper inner corner of the insertion rod exceeds the edge of the fixing groove, and the insertion rod is easily stuck in the fixing groove of the slider and cannot enter the inside of the slider, resulting in the slider being unable to move downward. Therefore, it is necessary to improve the structure of the fixing groove of the slider.

Figure 2 yes Figure 1 The three-dimensional schematic diagram of the slider shown in the first perspective, Figure 3 yes Figure 2 The three-dimensional schematic diagram of the slider shown in the second viewing angle, Figure 4 yes Figure 2 The front view of the slider shown in FIG. Figure 5 yes Figure 1 The schematic cross-section diagram of the slider shown, Figure 6 yes Figure 1 The slider shown is a top view of a zipper tape when the insert rod and the seat rod are turned outward to form an eight-shaped shape. Figure 7 yes Figure 6 The following is a partial enlarged schematic diagram of the pull head guiding the plug rod that is turned outward. Figures 1 to 7 The specific structure and operation method of the slider 100 according to one embodiment of the present invention are described, but the present invention is not limited thereto and can be adjusted according to needs.

[0063] Please refer to Figure 1In this embodiment, the slider 100 is suitable for being installed on the zipper tape 52 used in the zipper chain 50. The zipper tape 52 is a belt-shaped structure extending along the length direction L, and the inner side edges of a pair of zipper tapes 52 are provided with chain elements 54 arranged side by side along the length direction L. In addition, a pair of sliders 100 arranged oppositely are provided on the zipper tape 52 of the zipper chain 50 to form a double open-end zipper 20. The pair of sliders 100 are installed in groups on the zipper chain 50 and arranged oppositely, so as to open or close the chain elements 54 from the opposite sides of the zipper chain 50 by sliding, thereby opening or closing at least one of the opposite sides in the length direction L of the zipper chain 50 respectively. In addition, the zipper chain 50 is also provided with an insert rod 56 and a seat rod 58. The insert rod 56 and the seat rod 58 are respectively arranged on the pair of zipper tapes 52 and located at the ends of the arrangement position of the chain elements 54. When the slider 100 moves upward to open the lower end of the zipper chain 50, the insertion rod 56 and the seat rod 58 provided at the end of the zipper tape 52 are separated from each other. Accordingly, when the slider 100 moves downward to close the lower end of the zipper chain 50, the insertion rod 56 and the seat rod 58 provided at the end of the zipper tape 52 are close to each other and move to the inside of the slider 100 and engage with each other (for example, the insertion rod 56 is inserted into the seat rod 58). However, the present invention does not limit the application of the slider 100 on the zipper chain 50, nor does it limit the specific structure and type of the zipper and the zipper chain 50, which can be adjusted according to needs.

[0064] Specifically, in this embodiment, if Figures 1 to 5 As shown, the slider 100 includes a lower wing plate 110, an upper wing plate 120, and a guide post 130. The upper wing plate 120 is arranged opposite to the lower wing plate 110. The guide post 130 is arranged between the lower wing plate 110 and the upper wing plate 120, and connects the front end P1 of the lower wing plate 110 and the upper wing plate 120, while the rear end P2 of the lower wing plate 110 and the upper wing plate 120 opposite to the front end P1 is in an open state. Among them, a pair of sliders 100 are installed on the zipper tape 52 of the zipper chain 50 in a manner that the rear end P2 is arranged opposite to each other to form a double open-end zipper 20. However, the double open-end zipper 20 can also only use the slider 100 of this embodiment as the lower slider. Or, in other embodiments not shown, the slider 100 can also be installed separately on the zipper chain 50 to form a zipper with a single slider. The present invention does not limit whether the double-end zipper 20 uses a pair of sliders 100 with the same structure, nor does it limit the type of zipper to which the slider 100 is applied, and it can be adjusted according to needs.

[0065] Furthermore, in this embodiment, if Figures 1 to 5As shown, the inner surface of the lower wing plate 110 and the inner surface of the upper wing plate 120 are respectively provided with a pair of fixing grooves 140A and a pair of fixing grooves 140B located on opposite sides of the guide column 130 for the insertion rod 56 and the seat rod 58 of the zipper tape 52 to pass through. The inner surface of the lower wing plate 110 refers to the surface of the lower wing plate 110 facing the upper wing plate 120, and the inner surface of the upper wing plate 120 refers to the surface of the upper wing plate 120 facing the lower wing plate 110. In this way, the pair of fixing grooves 140A provided in the lower wing plate 110 and the pair of fixing grooves 140B provided in the upper wing plate 120 correspond to each other in the thickness direction T, so as to further form a space for the insertion rod 56 and the seat rod 58 to pass through in a pair of channels C formed on opposite sides of the guide column 130 for the fastener element 54 to pass through. Among them, the seat rod 58 can pass through the space formed by the fixing grooves 140A and the fixing grooves 140B in the channel C on one side of the guide column 130. After the slider 100 moves to the end of the zipper tape 52, the insert rod 56 and the seat rod 58 move to the inside of the slider 100 and engage with each other (for example, the insert rod 56 is inserted into the seat rod 58), and the stopper 58a provided at the end of the seat rod 58 can be engaged with the fixing groove 140A provided in the lower wing plate 110 (for example, the fixing groove 140A of the lower wing plate 110 is provided). Figure 1 As shown) or disposed on the fixing groove 140B of the upper wing plate 120, the seat bar 58 is fixed inside the slider 100 to prevent the slider 100 from moving further downward.

[0066] It can be seen that in this embodiment, since the slider 100 is provided with a space formed by the fixing groove 140A and the fixing groove 140B on opposite sides of the guide column 130, the slider 100 provided with the fixing groove 140A and the fixing groove 140B can be installed on the zipper tape 52 regardless of which end of the pair of zipper tapes 52 the seat bar 58 is provided, so that during operation, the stopper 58a provided on the seat bar 58 is engaged with the fixing groove 140A or the fixing groove 140B to fix the seat bar 58 inside the slider 100. In this way, the applicability of the slider 100 can be improved, so that it can be applied to different types of zipper chains ( Figure 1 The zipper chain 50 shown is an example of a zipper tape 52 in which the seat bar 58 is arranged on the right side. Furthermore, although the fixing grooves 140A and 140B provided inside the slider 100 are recessed structures for engaging the stopper 58a of the seat bar 58, since the fixing grooves 140A of the lower wing plate 110 and the fixing grooves 140B of the upper wing plate 120 are provided in pairs on opposite sides of the guide column 130, the insert rod 56 can also pass through the space formed by the fixing grooves 140A and 140B in the channel C on the other side of the guide column 130 (such as Figure 1That is, the space formed by the pair of fixing grooves 140A and the pair of fixing grooves 140B on the opposite sides of the guide column 130 can allow the insertion rod 56 and the seat rod 58 to pass through, thereby improving the applicability of the slider 100.

[0067] In addition, in this embodiment, Figures 2 to 5 As shown, a pair of fixing grooves 140A provided in the lower wing plate 110 or a pair of fixing grooves 140B provided in the upper wing plate 120 are provided with an inclined surface 150 corresponding to the outer edge or the inner edge in the width direction W. In addition, the inclined surface 150 includes a pair of first inclined surfaces 152 provided in the pair of fixing grooves 140A of the lower wing plate 110 and corresponding to the outer edge, or a pair of second inclined surfaces 154 provided in the pair of fixing grooves 140B of the upper wing plate 120 and corresponding to the inner edge. That is, the pair of fixing grooves 140A provided in the lower wing plate 110 are provided with a pair of first inclined surfaces 152 corresponding to the outer edge in the width direction W. Alternatively, the pair of fixing grooves 140B provided in the upper wing plate 120 are provided with a pair of second inclined surfaces 154 corresponding to the inner edge in the width direction W. Therefore, the slider 100 has at least a pair of inclined surfaces 150 (a pair of first inclined surfaces 152 provided in the pair of fixing grooves 140A or a pair of second inclined surfaces 154 provided in the pair of fixing grooves 140B).

[0068] So, like Figure 6 and Figure 7 As shown, in the present embodiment, when the insert rod 56 provided on the zipper tape 52 of the zipper chain 50 is flipped outward (for example, the insert rod 56 and the seat rod 58 are in an eight-shape), the outer corner C1 at the bottom of the flipped-outward insert rod 56 exceeds the edge of a pair of fixed grooves 140A provided on the lower wing plate 110 and the inner corner C2 at the upper side of the insert rod 56 exceeds the edge of a pair of fixed grooves 140B provided on the upper wing plate 120. In this case, during the downward movement of the slider 100 in the length direction L, the slider 100 can utilize the first inclined surface 152 corresponding to the outer edge of the lower wing plate 110 or the second inclined surface 154 corresponding to the inner edge of the upper wing plate 120 to guide the plunger 56 that is flipped outward, and the plunger 56 is flipped inward to a position corresponding to the fixing groove 140A and the fixing groove 140B (such as by moving the outer corner C1 at the bottom or the inner corner C2 at the top along the inclined surface 150) (for example, the outer corner C1 moves along the first inclined surface 152 or the inner corner C2 moves along the second inclined surface 154). Figure 7 As shown by the arrow in the figure), the plunger 56 can easily enter the fixing groove 140A and the fixing groove 140B on one side of the guide column 130 without getting stuck. Accordingly, the slider 100 can use the internal structure to guide the plunger 56 during operation, thereby having a smoother operation method.

[0069] Furthermore, in this embodiment, although the position adjustment of the plunger 56 is mainly described by the guidance of the inclined surface 150, since the slider 100 is provided with at least one pair of inclined surfaces 150 (a pair of first inclined surfaces 152 provided in the pair of fixed grooves 140A or a pair of second inclined surfaces 154 provided in the pair of fixed grooves 140B) on the pair of fixed grooves 140A and the pair of fixed grooves 140B, that is, the inclined surfaces 150 are provided in pairs on the lower wing plate 110 or the upper wing plate 120 of the slider 100. Therefore, if the seat bar 58 also exceeds the edge of the pair of fixing grooves 140A or the pair of fixing grooves 140B due to flipping outward, the inclined surface 150 also adjusts the seat bar 58 during the process of the slider 100 moving downward in the length direction L, so that the seat bar 58 flips inward to a position corresponding to the fixing grooves 140A and 140B, so that the seat bar 58 can easily enter the fixing grooves 140A and 140B on the other side of the guide column 130 without getting stuck. Accordingly, the slider 100 can use the internal structure to guide the seat bar 58 during operation, thereby having a smoother operation method.

[0070] Furthermore, in this embodiment, if Figures 2 to 5 As shown, a pair of lower flanges 112 extending along the outer edge of the lower wing plate 110 are provided on the left and right sides in the width direction W, and a pair of fixing grooves 140A are provided in the area between the guide column 130 and the pair of lower flanges 112. The side of the lower wing plate 110 corresponding to the outer edge refers to the side close to the lower flange 112, and the side of the lower wing plate 110 corresponding to the inner edge refers to the side close to the guide column 130. Correspondingly, a pair of upper flanges 122 extending along the outer edge of the upper wing plate 120 are provided on the left and right sides in the width direction W, and a pair of fixing grooves 140B are provided in the area between the guide column 130 and the pair of upper flanges 122. The side of the upper wing plate 120 corresponding to the outer edge refers to the side close to the upper flange 122, and the side of the upper wing plate 120 corresponding to the inner edge refers to the side close to the guide column 130. Preferably, a pair of fixing grooves 140A are symmetrically arranged on opposite sides of the guide column 130 on the inner surface of the lower wing plate 110 with the length direction L as the reference, and a pair of fixing grooves 140B are symmetrically arranged on opposite sides of the guide column 130 on the inner surface of the upper wing plate 120 with the length direction L as the reference. In addition, the pair of fixing grooves 140A arranged on the lower wing plate 110 and the pair of fixing grooves 140B arranged on the upper wing plate 120 are symmetrically arranged in the thickness direction T and have the same structure.

[0071] Furthermore, in this embodiment, if Figures 2 to 5As shown, a pair of fixing grooves 140A provided on the lower wing plate 110 and a pair of fixing grooves 140B provided on the upper wing plate 120 are respectively provided as groove structures, and the fixing grooves 140A and the fixing grooves 140B are respectively in an open state at their respective locations facing the front end portion P1 ( Figure 5 The fixing groove 140A of the lower wing plate 110 is taken as an example. Among them, the side surfaces corresponding to the outer edges (i.e., close to the lower flange 112) of the pair of fixing grooves 140A provided in the lower wing plate 110 are inclined relative to the inner surface of the lower wing plate 110 to form a first inclined surface 152. Alternatively, the side surfaces corresponding to the inner edges (i.e., close to the guide column 130) of the pair of fixing grooves 140B provided in the upper wing plate 120 are inclined relative to the inner surface of the upper wing plate 120 to form a second inclined surface 154. In this way, at least a pair of first inclined surfaces 152 or a pair of second inclined surfaces 154 provided in the pair of fixing grooves 140A and the pair of fixing grooves 140B that are arranged opposite to each other in the thickness direction T can guide the plunger 56 passing through one of the opposite sides of the guide column 130 of the slider 100. However, the present invention does not limit the specific structures and relative relationships of the pair of fixing grooves 140A and the pair of fixing grooves 140B, which can be adjusted according to needs.

[0072] Furthermore, in this embodiment, if Figures 2 to 5 As shown, preferably, the inclined surface 150 includes a pair of first inclined surfaces 152 disposed on a pair of fixing grooves 140A of the lower wing plate 110 and corresponding to the outer edge, and a pair of second inclined surfaces 154 disposed on a pair of fixing grooves 140B of the upper wing plate 120 and corresponding to the inner edge. Thus, the slider 100 has at least two pairs of inclined surfaces 150 (a pair of first inclined surfaces 152 disposed in a pair of fixing grooves 140A and a pair of second inclined surfaces 154 disposed in a pair of fixing grooves 140B). That is to say, the first inclined surface 152 corresponding to the outer edge of the lower wing plate 110 is used to guide the lower outer corner C1 of the insert rod 56, and the second inclined surface 154 corresponding to the inner edge of the upper wing plate 120 is used to guide the upper inner corner C2 of the insert rod 56. The lower outer corner C1 and the upper inner corner C2 of the insert rod 56 that flips outward and exceeds the edges of the fixing grooves 140A and 140B can be guided at the same time, thereby making the process of the insert rod 56 moving into the fixing grooves 140A and 140B of the pulling head 100 more stable.

[0073] In addition, in this embodiment, Figures 2 to 5As shown, although two pairs of inclined surfaces 150 (a pair of first inclined surfaces 152 and a pair of second inclined surfaces 154) are provided in the fixing groove 140A and the fixing groove 140B of the slider 100 in response to common situations to guide the plunger 56 that flips outward from the outer side below and the inner side above, as an example, more inclined surfaces 150 can also be provided in the fixing groove 140A and the fixing groove 140B of the slider 100. For example, the inclined surfaces 150 also include a pair of third inclined surfaces 156 provided on the pair of fixing grooves 140A of the lower wing plate 110 and corresponding to the inner side edge, and a pair of fourth inclined surfaces 158 provided on the pair of fixing grooves 140B of the upper wing plate 120 and corresponding to the outer side edge. That is, the pair of fixing grooves 140A provided on the lower wing plate 110 respectively have a pair of first inclined surfaces 152 corresponding to the outer side edge, and a pair of fourth inclined surfaces 158 corresponding to the inner side edge. Furthermore, the pair of fixing grooves 140B provided on the upper wing plate 120 respectively have a pair of second inclined surfaces 154 corresponding to the inner edge, and a pair of third inclined surfaces 156 corresponding to the inner edge. Thus, the slider 100 has four pairs of inclined surfaces 150 (a pair of first inclined surfaces 152, a pair of second inclined surfaces 154, a pair of third inclined surfaces 156, and a pair of fourth inclined surfaces 158). However, the present invention is not limited thereto, and it can be adjusted according to needs.

[0074] Furthermore, in this embodiment, if Figure 4 As shown, the first inclined surface 152 and the third inclined surface 156 correspond to each other in the thickness direction T and have similar structures, and the second inclined surface 154 and the fourth inclined surface 158 correspond to each other in the thickness direction T and have similar structures. That is, the features of the first inclined surface 152 described later are also applicable to the third inclined surface 156, and the features of the second inclined surface 154 described later are also applicable to the fourth inclined surface 158. In addition, the lower wing plate 110 in which a pair of first inclined surfaces 152 and a pair of fourth inclined surfaces 158 are respectively provided in a pair of fixing grooves 140A, and the upper wing plate 120 in which a pair of second inclined surfaces 154 and a pair of third inclined surfaces 156 are respectively provided in a pair of fixing grooves 140B have substantially the same structure (i.e., symmetrically arranged in the thickness direction T), and the pair of fixing grooves 140A in which a pair of first inclined surfaces 152 and a pair of fourth inclined surfaces 158 are provided and the pair of fixing grooves 140B in which a pair of second inclined surfaces 154 and a pair of third inclined surfaces 156 are provided are bilaterally symmetrical with the guide post 130 as the center. Accordingly, the applicability of the slider 100 can be improved so as to be applied to various types of zipper chains 50. However, as long as the slider 100 has at least a pair of first inclined surfaces 152 (provided on the lower wing plate 110 and corresponding to the outer edge) or a pair of second inclined surfaces 154 (provided on the upper wing plate 120 and corresponding to the inner edge), the present invention is not limited thereto.

[0075] In addition, in this embodiment, Figure 4 and Figure 5 As shown, when a pair of first inclined surfaces 152 and a pair of second inclined surfaces 154 are provided at the same time, the inclination angle θ1 of each first inclined surface 152 relative to the inner surface of the lower wing plate 110 is smaller than the inclination angle θ2 of each second inclined surface 154 relative to the inner surface of the upper wing plate 120. As an example, the inclination angle θ1 of each first inclined surface 152 relative to the inner surface of the lower wing plate 110 is between 1 degree and 89 degrees, and the inclination angle θ2 of each second inclined surface 154 relative to the inner surface of the upper wing plate 120 is between 1 degree and 89 degrees. In other words, the first inclined surface 152 disposed at the lower wing plate 110 and corresponding to the outer edge is more gentle than the second inclined surface 154 disposed at the upper wing plate 120 and corresponding to the inner edge, so that the outer corner C1 below the plunger 56 flipped outward can be more effectively guided from the outside to the inside of the slider 100. In the case where a pair of third inclined surfaces 156 and a pair of fourth inclined surfaces 158 are further provided, the inclination angles of the third inclined surfaces 156 and the fourth inclined surfaces 158 can also be set with reference to the above relative relationship. However, the present invention is not limited thereto and can be adjusted according to requirements.

[0076] Furthermore, in this embodiment, if Figure 2 and Figure 5 As shown, when the inclined surface 150 includes a pair of first inclined surfaces 152 disposed on a pair of fixing grooves 140A of the lower wing plate 110 and corresponding to the outer edges, the dimension of each first inclined surface 152 in the length direction L of the lower wing plate 110 (for example, the length L1) is greater than the dimension of the guide post 130 in the length direction L (for example, the length L2), and each of the pair of first inclined surfaces 152 extends from the front end portion P1 of the lower wing plate 110 to the middle portion P3 of the lower wing plate 110 more than the guide post 130. In addition, as Figure 3 As shown, when the inclined surface 150 includes a pair of second inclined surfaces 154 provided on a pair of fixing grooves 140B of the upper wing plate 120 and corresponding to the inner edge, the size of each second inclined surface 154 in the length direction L of the upper wing plate 120 (for example, refer to the following Figure 5 The length L3 of the fourth inclined surface 158 is greater than the dimension of the guide column 130 in the length direction L (for example, the length L2), and a pair of second inclined surfaces 154 each extend from the front end portion P1 of the upper wing plate 120 toward the middle portion P3 of the upper wing plate 120 compared to the guide column 130.

[0077] Similarly, in this embodiment, if Figure 3As shown, when the inclined surface 150 further includes a pair of third inclined surfaces 156 disposed on the pair of fixing grooves 140B of the upper wing plate 120 and corresponding to the outer edges, the dimensions of each third inclined surface 156 in the length direction L of the upper wing plate 120 can also be set with reference to the first inclined surface 152 (for example, with reference to Figure 5 The first inclined surface 152 has a length L1) and extends further toward the middle portion P3 of the upper wing plate 120 than the guide post 130. Figure 2 and Figure 5 As shown, when the inclined surface 150 also includes a pair of fourth inclined surfaces 158 provided on the pair of fixing grooves 140A of the lower wing plate 110 and corresponding to the inner edge, each fourth inclined surface 158 can also be set with reference to the second inclined surface 154 to have a dimension (for example, length L3) in the length direction L of the lower wing plate 110 and extend toward the middle portion P3 of the lower wing plate 110 more than the guide post 130. In this way, the pair of fixing grooves 140A and the pair of fixing grooves 140B provided in the slider 100 can guide the insert rod 56 and the seat rod 58 toward the middle portion P3 of the lower wing plate 110 and the upper wing plate 120 more closely than the guide post 130, so that the insert rod 56 and the seat rod 58 can be reliably moved to the interior of the slider 100 and engaged with each other (as shown in FIG. 1 ). Figure 1 However, the present invention does not limit the relative relationship between the inclined surface 150 and the guide column 130, which can be adjusted according to needs.

[0078] Furthermore, in this embodiment, if Figure 2 and Figure 5 As shown, when the inclined surface 150 includes a pair of first inclined surfaces 152 disposed on a pair of fixing grooves 140A of the lower wing plate 110 and corresponding to the outer edge, the inner surface of the lower wing plate 110 is further provided with a pair of guide surfaces 114 located on opposite sides of the guide column 130 and corresponding to the front end portion P1 of the lower wing plate 110 to guide the fastener elements 54 of the zipper tape 52. The pair of guide surfaces 114 are connected to the pair of first inclined surfaces 152, and the pair of guide surfaces 114 are located further outward than the pair of first inclined surfaces 152 in the width direction W. In this way, as shown in FIG. Figure 1 and Figure 6 As shown in FIG. 1 , when the slider 100 moves downward in the length direction L, the guide surface 114 can guide the chain element 54 from the side corresponding to the outer edge of the slider 100 in the width direction W toward the guide column 130, thereby facilitating the alignment and mutual engagement of the chain elements 54 that are separated from each other and arranged on a pair of zipper tapes 52 (i.e., closing the chain elements 54). Similarly, a pair of guide surfaces 124 (such as Figure 3 and Figure 4As shown). In other embodiments not shown, when a pair of first inclined surfaces 152 is not provided but a pair of second inclined surfaces 154 is provided, a pair of guide surfaces 114 for guiding the chain elements 54 may also be provided on the lower wing plate 110 (not limited to being provided simultaneously with the first inclined surfaces 152). Alternatively, the provision of the guide surfaces 114 and the guide surfaces 124 may be omitted. The present invention is not limited to this and can be adjusted according to needs.

[0079] Preferably, in this embodiment, if Figure 2 and Figure 5 As shown, the size of each guide surface 114 provided on the inner surface of the lower wing plate 110 in the length direction L of the lower wing plate 110 (i.e., the length L4) is smaller than the size of each first inclined surface 152 in the length direction L (i.e., the length L1), and the size of each guide surface 114 in the width direction W of the lower wing plate 110 (i.e., the width W1) is larger than the size of each first inclined surface 152 in the width direction W (i.e., the width W2). That is, the first inclined surface 152 is configured as a long strip-shaped surface corresponding to the outer edge of a pair of fixed grooves 140A, so as to guide the insert rod 56 (or further including the seat rod 58) to the inside of the slider 100 in the length direction L, and the guide surface 114 is configured as a generally fan-shaped surface provided on the outer side relative to the pair of fixed grooves 140A, so as to guide the chain element 54 to the inside of the slider 100 in the width direction W. However, the present invention is not limited thereto, and it can be adjusted according to needs.

[0080] In addition, in this embodiment, Figure 2 and Figure 5 As shown, the inner surface of the lower wing plate 110 is also provided with a pair of connecting surfaces 116 located on opposite sides of the guide column 130 and each extending along the edge of the front end portion P1 of the lower wing plate 110. Furthermore, the pair of connecting surfaces 116 each extend from a pair of guide surfaces 114 toward the guided column 130 to serve as the front end surface of a pair of fixed grooves 140A provided on the lower wing plate 110. That is, each connecting surface 116 is provided at the edge of the front end portion P1 of the lower wing plate 110 and spans the corresponding guide surface 114 and the guide column 130 and passes through the corresponding fixed groove 140A. In this way, during the process of the slider 100 moving downward in the length direction L, the chain element 54 guided by the guide surface 114 can easily enter the fixed groove 140A through the connecting surface 116. Similarly, a pair of connecting surfaces 126 (such as Figure 3 and Figure 4As shown). In other embodiments not shown, when a pair of first inclined surfaces 152 is not provided but a pair of second inclined surfaces 154 is provided, a pair of connecting surfaces 116 may also be provided on the lower wing plate 110 (not limited to being provided simultaneously with the first inclined surfaces 152 or the guide surfaces 114). Alternatively, the connection surfaces 116 and the connection surfaces 126 may be omitted. The present invention is not limited thereto and may be adjusted according to requirements.

[0081] Preferably, in this embodiment, if Figure 2 and Figure 5 As shown, the size of each connecting surface 116 in the length direction L of the lower wing plate 110 (for example, the length L5) is smaller than the size of each guiding surface 114 in the length direction L (i.e., the length L4), and the size of each connecting surface 116 in the width direction W of the lower wing plate 110 (i.e., the width W3) is larger than the size of each guiding surface 114 in the width direction W (i.e., the width W1). In other words, each connecting surface 116 is configured as a long strip-shaped surface corresponding to the front end portion P1 of a pair of fixing grooves 140A, so as to guide the fastener element 54 or the insert rod 56 (or further including the seat rod 58) from the front end portion P1 to the inside of the slider 100 in the width direction W. However, the present invention is not limited thereto, and it can be adjusted according to needs.

[0082] In summary, in the slider of the present invention, the inner surface of the lower wing plate and the inner surface of the upper wing plate are each provided with a pair of fixing grooves located on opposite sides of the guide column, and the pair of fixing grooves provided on the lower wing plate or the pair of fixing grooves provided on the upper wing plate are provided with inclined surfaces corresponding to the outer edge or the inner edge in the width direction, and the inclined surfaces include a pair of first inclined surfaces provided on the pair of fixing grooves of the lower wing plate and corresponding to the outer edge, or a pair of second inclined surfaces provided on the pair of fixing grooves of the upper wing plate and corresponding to the inner edge. Preferably, the inclined surfaces include a pair of first inclined surfaces and a pair of second inclined surfaces, and the inclination angle of each first inclined surface relative to the inner surface of the lower wing plate is smaller than the inclination angle of each second inclined surface relative to the inner surface of the upper wing plate. In this way, the slider can use the first inclined surface corresponding to the outer edge of the lower wing plate or the second inclined surface corresponding to the inner edge of the upper wing plate to guide the plunger that is flipped outward, and by moving the lower outer corner or the upper inner corner of the plunger along the inclined surface, the plunger is flipped inward to a position corresponding to the fixed groove, so that the plunger can easily enter the fixed groove on one side of the guide column. Accordingly, the slider of the present invention can use the internal structure to guide the plunger during operation, thereby having a smoother operation method.
