[0047] Some zipper sliders consist of a base, a base block, and a decorative piece. The base moves to open and close the two zipper strips. The base block is connected to the base, and the decorative piece is detachably connected to the base block, allowing for replacement of decorative pieces with different shapes and patterns as needed. However, in existing detachable sliders, the decorative piece and base block are not firmly connected after assembly, and the two easily separate, resulting in a poor user experience.

[0048] The following is a preferred embodiment of a detachable injection-molded slider provided by the present invention that can solve the above technical problems.

[0049] Please refer to Figures 1-4 The preferred embodiment of the present invention provides a detachable injection-molded slider, which includes a base (not shown in the figure), a base block 11 and a decorative piece 12. One end of the base block 11 is connected to the base, and a receiving groove 111 is provided on the front of the base block 11. A limiting strip 112 is provided at the notch of the receiving groove 111. The limiting strip 112 is a ring-shaped strip provided along the notch edge of the receiving groove 111. The decorative piece 12 includes a clamping block 121, a connecting block 123 and a decorative block 122 connected in sequence. The clamping block 121 is made of plastic and is detachably arranged in the receiving groove 111. The connecting block 123 is passed through the ring surrounded by the limiting strip 112. The decorative block 122 is located outside the base block 11. When the clamping block 121 is located in the receiving groove 111, the limiting strip 112 is located between the clamping block 121 and the decorative block 122 to limit the clamping block 121 in the receiving groove 111.

[0050] The detachable injection-molded slider of the present invention has a base that moves to separate and connect the two zipper strips. The decorative block 122 is exposed outside the limiting groove and is located on the front of the base block 11, which can serve a decorative purpose. When installing the decorative part 12, the decorative block 122 is pressed inward, and the clamping block 121 is deformed, so that the clamping block 121 can pass through the limiting strip 112. When removing the decorative part 12, the decorative block 122 is pulled outward with a greater force, and the clamping block 121 is deformed, so that the clamping block 121 can pass through the limiting strip 112. The clamping block 121 is located in the receiving groove 111, and the annular limiting strip 112 can be used to reliably limit the clamping block 121 in the receiving groove 111. If the decorative part 12 is not pulled outward with a greater force, the decorative part 12 will not separate from the base block 11. The detachable injection-molded slider of the present invention has a base block 11 and a decorative part 12 that are not easily separated when assembled together, effectively improving the user experience.

[0051] Please refer to Figure 3 The inner wall of the limiting strip 112 is inclined, and the inner diameter of the ring gradually increases along the opening direction of the receiving groove 111. When assembling the base block 11 and the decorative member 12, it is convenient for the clamping block 121 to enter the receiving groove 111.

[0052] Please refer to Figure 3 and Figure 4 The limiting strip 112 is a regular pentagonal ring, the snap-connecting block 121 is a regular pentagon with one corner missing, and the accommodating groove 111 is a regular pentagon, so that the accommodating groove 111, the limiting strip 112 and the snap-connecting block 121 have a stable structure, and the limiting strip 112 and the snap-connecting block 121 are not easily damaged during assembly and disassembly.

[0053] Please refer to Figure 4 A first inclined surface 1211 is provided at the missing corner of the clamping block 121, and a second inclined surface 1212 is provided at the side of the clamping block 121 opposite the missing corner. Both the first inclined surface 1211 and the second inclined surface 1212 make the bottom surface area of the clamping block 121 smaller than the top surface area of the clamping block 121. The first inclined surface 1211 and the second inclined surface 1212 facilitate passing the clamping block 121 through the limiting strip 112.

[0054] Please continue to refer to Figure 4 The decorative block 122 has an inclined first avoidance surface 1221 and an inclined second avoidance surface 1222 at opposite ends thereof, facing the engaging block 121. Both the first avoidance surface 1221 and the second avoidance surface 1222 ensure that the bottom surface area of the decorative block 122 is smaller than the top surface area of the decorative block 122. When separating the base block 11 and the decorative member 12, the first avoidance surface 1221 and the second avoidance surface 1222 facilitate the user's fingers to reach under the decorative block 122, preventing slipping when the decorative block 122 is pulled outward with force.

[0055] Please refer to Figure 2 The detachable injection molded slider further comprises a pull rope 13, which is connected to the decorative member 12 and extends in a direction away from the base. The pull rope 13 facilitates pulling the detachable injection molded slider.

[0056] Please continue to refer to Figure 2 The pull cord 13 and the decorative part 12 are integrally injection molded, so that the pull cord 13 is firmly fixed and not easily separated from the decorative part 12.

[0057] Please continue to refer to Figure 2 The length direction of the pull rope 13 is perpendicular to the plugging direction of the clamping block 121 and the accommodating groove 111. When the pull rope 13 is pulled, the clamping block 121 will not be pulled out.

[0058] The working principle of the detachable injection-molded slider of the first preferred embodiment of the utility model is as follows:

[0059] When installing the decorative piece 12, press the decorative block 122 hard, causing the snap-on block 121 to deform. Simultaneously, the first inclined surface 1211 and the second inclined surface 1212 are used to allow the snap-on block 121 to pass through the limiting strip 112. When removing the decorative piece 12, extend your fingers toward the first avoidance surface 1221 and the second avoidance surface 1222, and use a strong force to pull the decorative piece 122 outward. This causes the snap-on block 121 to deform, allowing the snap-on block 121 to pass through the limiting strip 112. When the snap-on block 121 is located in the receiving groove 111, the annular limiting strip 112 can be used to reliably limit the snap-on block 121 in the receiving groove 111. If the decorative piece 12 is not pulled outward with a strong force, the decorative piece 12 will not separate from the base block 11. During normal use, pulling the drawstring 13 drives the decorative piece 12, base block 11, and base to move, thereby achieving the separation and combination of the two zipper straps.

[0060] This completes the assembly process of the detachable injection-molded slider of the preferred embodiment.

[0061] Please refer to Figure 5-Figure 8 The second preferred embodiment of the present invention provides a detachable injection-molded slider. This differs from the first embodiment in that a snap-in groove 113 is further provided on the front of the base block 11, connecting the accommodating groove 111, the front of the base block 11, and the end face of the base block 11 facing away from the base. A pull cord 13 is connected to the connecting block 123, and the pull cord 13 is interference fit within the snap-in groove 113. The pull cord 13 cooperates with the snap-in groove 113 to enhance the connection strength between the decorative component 12 and the base block 11, and the snap-in block 121 is not easily pulled out when the pull cord 13 is pulled. The other structures of this embodiment are substantially the same as those of the first embodiment and will not be described in detail here.

[0062] Please refer to Figures 9-14The third preferred embodiment of the present invention provides a detachable injection-molded slider. This differs from the first embodiment in that the base block 11 is further provided with a first through-hole 114 and a second through-hole 115. The first through-hole 114 connects the receiving slot 111 with the end surface of the base block 11 facing away from the base, while the second through-hole 115 connects the receiving slot 111 with the back surface of the base block 11. A pull cord 13 is connected to the side of the connecting block 121 facing away from the decorative block 122. The pull cord 13 passes through the second through-hole 115 and then through the first through-hole 114. When assembling the base block 11 and the decorative member 12, the pull cord 13 is first passed through the second through-hole 115 and then pulled away from the decorative block 122. This makes it easier for the connecting block 121 to enter the receiving slot 111. The pull cord 13 is then passed through the first through-hole 114, making it less likely that the connecting block 121 will be pulled out. The remaining structures of this embodiment are substantially the same as those of the first embodiment and will not be further described here.

[0063] The detachable injection-molded slider of the present invention is designed so that the two zipper tapes can be separated and combined when the base moves. The decorative block is exposed outside the limiting groove and is located on the front of the base block, which can play a decorative role. When installing the decorative part, press the decorative block inward, and the snap-in block is deformed, so that the snap-in block can pass through the limiting strip. When removing the decorative part, use a greater force to pull the decorative block outward, and the snap-in block is deformed, so that the snap-in block can pass through the limiting strip. The snap-in block is located in the receiving groove, and the annular limiting strip can be used to reliably limit the snap-in block in the receiving groove. If the decorative part is not pulled outward with a greater force, the decorative part will not separate from the base block. The detachable injection-molded slider of the present invention is designed so that when the base block and the decorative part are assembled together, the two are not easy to separate, which effectively improves the user experience.

[0064] 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.
