The directional terms used are used to illustrate and understand the invention, and are not intended to limit the invention.

[0041] The terms "first" and "second" in the present invention are used for descriptive purposes only and should not be understood as indicating or implying relative importance, nor as limiting the order of precedence.

[0042] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0043] The slider consists of a base and a zipper tab. Pulling the zipper tab moves the base, allowing the two zipper strips to open and close. Some zipper tabs consist of a metal component and an injection-molded part. The metal component is connected to the base. The metal component is made of a durable material. The injection-molded part is then assembled with the metal component. This increases the length of the zipper tab, making it more convenient to use and saving costs. However, in conventional assembled zipper tabs, the assembly of the injection-molded and metal components is difficult, affecting processing efficiency.

[0044] The following is a preferred embodiment of a slider provided by the present invention that can solve the above technical problems.

[0045] Please refer to Figure 1 、 Figure 2 and Figure 3 The first preferred embodiment of the present invention provides a slider, which includes a base 2 and a quick-assembly zipper piece 1.

[0046] Please refer to Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 7 The quick assembly zipper sheet 1 includes a metal piece 11 and an injection molded piece 12. The metal piece 11 has a first direction ( Figure 2 The first end 111 and the second end 112 are arranged in the x direction (the same below), the first end 111 is connected to the base 2, and the second end 112 is provided with two slots 113. The two slots 113 are arranged along the second direction ( Figure 2 The slots 113 are arranged along the third direction ( Figure 3 The z direction in the third direction, the same below) passes through the metal part 11, and the third direction is perpendicular to the first direction and the second direction. The slot 113 has a relief opening 1131 and a bottom surface 1132. The relief opening 1131 is provided on a side of the metal part 11 located in the second direction, and the bottom surface 1132 is opposite to the relief opening 1131. The injection molded part 12 includes an extension piece 121 and two plug-in blocks 122. The two plug-in blocks 122 protrude from a side of the extension piece 121 located in the third direction, and the two plug-in blocks 122 are arranged along the second direction. The two plug-in blocks 122 are respectively limited in the two slots 113, and the bottom surfaces 1132 of the two slots 113 are respectively in contact with the side surfaces of the two plug-in blocks 122.

[0047] The quick-assembly zipper piece 1 and slider of the present invention connect the metal part 11 and the injection molded part 12 by inserting two insert blocks 122 into the two slots 113, respectively. When the insert block 122 is inserted into the slot 113, the side walls of the slot 113 squeeze the insert block 122. The insert block 122 has a certain degree of ductility and can extend in the direction of the avoidance opening 1131, so that the insert block 122 can smoothly enter the slot 113. Because the insert block 122 is limited in the slot 113, it is difficult for the insert block 122 to escape from the slot 113 in the first and third directions. Because the two bottom surfaces 1132 can respectively limit the side surfaces of the two insert blocks 122, it is also difficult for the insert block 122 to escape from the slot 113 in the second direction. The quick-assembly zipper piece 1 and slider of the present invention, both of which are provided with avoidance openings 1131 in the two slots 113, can quickly assemble the metal part 11 and the injection molded part 12, and the two are not easily separated.

[0048] Please refer to Figure 6 , please also refer to Figure 1 Insert block 122 includes a main block 1221 and a hook 1222. Main block 1221 is connected to extension piece 121. Hook 1222 is located at the end of main block 1221 facing away from extension piece 121. Hook 1222 protrudes from the side of main block 1221. Hook 1222 engages with the side of metal component 11 facing away from extension piece 121, preventing separation of metal component 11 from injection molded component 12. In other embodiments, insert block 122 can also be interference fit in slot 113.

[0049] Please refer to Figure 6 The hook 1222 protrudes from the side of the main body block 1221 close to the first end 111 in the first direction, which can ensure that the metal part 11 and the injection molded part 12 are not easily separated and make the hook 1222 easy to pass through the slot 113.

[0050] Please refer to Figure 7 , please also refer to Figure 3 A limiting groove 1133 is provided on the side wall of the slot 113 opposite the hook 1222, and the hook 1222 is positioned within the limiting groove 1133. The limiting groove 1133 can accommodate the hook 1222, thereby protecting the connection between the hook 1222 and the main body 1221 and effectively preventing the hook 1222 from being located outside the metal component 11 and being easily damaged.

[0051] Please refer to Figure 6 and Figure 7 , please also refer to Figure 3In the first direction, the hook 1222 abuts against the wall of the limiting groove 1133, and the main block 1221 abuts against the wall of the slot 113. In the third direction, the extension piece 121 abuts against the metal component 11, and the hook 1222 abuts against the bottom wall of the limiting groove 1133. This structure makes it difficult for the injection molded part 12 to move relative to the metal component 11 in both the first and third directions, thereby improving the integrity of the zipper tab 1 during rapid assembly.

[0052] Please refer to Figure 6 , please also refer to Figure 3 An inclined first guide surface 12211 is provided on the side of the main body block 1221 away from the hook 1222. The first guide surface 12211 is connected to the end surface of the main body block 1221 away from the extension piece 121. The end of the first guide surface 12211 away from the extension piece 121 is inclined toward the direction close to the hook 1222, so that the main body block 1221 and the hook 1222 can easily pass through the slot 113.

[0053] Please refer to Figure 6 , please also refer to Figure 3 The hook 1222 is provided with a second guide surface 12221 connected to the end of the main body 1221 away from the extension piece 121. The end of the second guide surface 12221 away from the extension piece 121 is inclined toward the first guide surface 12211, so that the hook 1222 can easily pass through the slot 113.

[0054] Please refer to Figure 7 , please also refer to Figure 3 The side wall of the slot 113 near the hook 1222 is further provided with an inclined third guide surface 1134. The third guide surface 1134 is located on the side of the limiting slot 1133 near the extension piece 121 and is connected to the limiting slot 1133. The end of the third guide surface 1134 near the extension piece 121 is inclined in a direction away from the first guide surface 12211, making it easier for the hook 1222 to pass through the slot 113.

[0055] The assembly process of the quick assembly zipper sheet 1 of the first preferred embodiment of the present invention is as follows:

[0056] The two inserts 122 are respectively inserted into the two slots 113, with the hooks 1222 positioned within the retaining grooves 1133, to achieve the connection between the metal component 11 and the injection molded component 12. When the inserts 122 are inserted into the slots 113, the sidewalls of the slots 113 squeeze the inserts 122. The inserts 122 have a certain degree of ductility, allowing them to extend toward the clearance openings 1131, allowing them to smoothly enter the slots 113. Furthermore, during the insertion of the inserts 122 into the slots 113, the first guide surfaces 12211, the second guide surfaces 12221, and the third guide surfaces 1134 all provide guidance, facilitating the insertion of the main body 1221 and the hooks 1222 through the slots 113.

[0057] This completes the assembly process of the quick assembly zipper tab 1 of the preferred embodiment.

[0058] Please refer to Figure 8 and Figure 9 In the second preferred embodiment of the quick-assembly zipper tab 1 of the present invention, the hook 1222 protrudes from the side of the main body 1221 facing away from the first end 111 in the first direction. When the extension tab 121 is pulled, the hook 1222 is less likely to disengage from the slot 113. In other embodiments, the hook 1222 may protrude from the side of the main body 1221 in the second direction closer to the bottom surface 1132, or two hooks 1222 may be provided, one on each side of the main body 1221 in the first direction.

[0059] The other structures of this embodiment are similar to those of the first embodiment and will not be described again here.

[0060] The quick-assembly zipper piece and slider of the present invention realizes the connection between the metal part and the injection-molded part by inserting two plug-ins into two slots respectively. When the plug-in block is inserted into the slot, the side wall of the slot squeezes the plug-in block. The plug-in block has a certain ductility and can extend in the direction of the avoidance opening, so that the plug-in block can smoothly enter the slot. Since the plug-in block is limited in the slot, it is difficult for the plug-in block to escape from the slot along the first direction and the third direction. Since the two bottom surfaces can limit the side surfaces of the two plug-ins respectively, it is also difficult for the plug-in block to escape from the slot along the second direction. The quick-assembly zipper piece and slider of the present invention, both of which have avoidance openings, can enable the metal part and the injection-molded part to be quickly assembled, and the two are not easily separated.

[0061] To sum up, although the present invention has been disclosed as above in terms of preferred embodiments, the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent substitutions or changes based on the concept of the technical solution of the present invention, should be covered by the scope of protection of the present invention.
