Description

Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to a slider which is convenient for disassembly, assembly and replacement. Background Art

[0002] A zipper is a connector that relies on continuously arranged chain teeth to connect or separate objects. It is now widely used in clothing, bags, tents, etc. A zipper consists of chain teeth, a pull head, limit codes (front code and rear code) or locking parts. Its structure mainly consists of a zipper head and a pair of cloth tapes with chain teeth.

[0003] When installing and using existing zipper pullers, the pull tabs and the pull heads mostly adopt an integral structure. Once damaged, they cannot be repaired and need to be replaced with new pull tabs or pull heads. Currently, when replacing a new zipper pull head, the lock edge of one end of the cloth tape with the chain teeth needs to be removed, and then the new zipper pull head needs to be installed and then sewn. The removal and sewing of the stitches require certain skills and a certain amount of time. The operation is very inconvenient, which brings certain adverse effects to people's use process. In order to solve the shortcomings of the existing technology, we propose a zipper pull head that is easy to disassemble and replace. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] Embodiment 1, as Figure 1-4 As shown, a slider that is easy to disassemble, assemble and replace comprises an upper wing piece 1. When installing the slider, the lower wing piece 6 can be placed on the bottom side of the cloth belt with the chain teeth, and the lower engaging block 9 is pressed against the bottom side of the cloth belt. Then, the slot 2 of the upper wing piece 1 is installed flush along the pull nose support core group 4. When the bottom outer surface of the upper wing piece 1 touches the blocking block 5, the buckle plate 7 is pulled so that the buckle plate 7 drives the blocking block 5 to retract along the direction of the pull nose support core group 4 until it retracts to the inside of the pull nose support core group 4. Then, the upper wing piece 1 continues to be pressed downward along the pull nose support core group 4 until the bottom outer surface of the upper wing piece 1 touches the limiting groove 8 and stops. Then, the buckle plate 7 is released, and the blocking block 5 loses the pull of the buckle plate 7 and pops out, and the limiting groove 8 is used to achieve the precise blocking of the upper wing piece 1. The upper wing 1 and the nose pull core group 4 are combined, thereby completing the limiting fixation of the upper wing 1 and the nose pull core group 4, completing the assembly of the upper wing 1 and the lower wing 6, and realizing the rapid installation of the slider. After the installation of the slider is completed, by pressing the pressing block 13, the pressing block 13 is squeezed along the direction of the pull-tab connecting lock 12, so that the reset spring 15 is compressed, thereby exposing the notch of the pull-tab connecting lock 13. At this time, the pressing block 13 is installed along the notch into the nose pull groove 10 set on the inner side of the nose pull core group 4. After the pressing block 13 is installed in the nose pull groove 10, the pressing block 13 is released, the pressure brought by the pressing block 13 is lost, the reset spring 15 is reset, and the pressing block 13 is driven to slide outward, thereby driving the pull-tab connecting lock 12 to reset again, thus completing the installation of the pull tab 11.

[0023] Embodiment 2, as Figure 1-4 As shown, a slider that is easy to disassemble, assemble and replace. During disassembly, the pressing block 13 is pressed first, so that the pressing block 13 is squeezed along the direction of the pull-tab connecting lock 12, so that the reset spring 15 is compressed, thereby exposing the notch of the pull-tab connecting lock 13. At this time, the pull tab 11 is taken out from the pull nose groove 10, and then the pressing block 13 is released. In this way, the disassembly of the pull tab is completed, and then the buckle plate 7 is triggered to make the buckle plate 7 drive the positioning block 5 to shrink along the direction of the pull nose support core group 4 until it shrinks to the inner side of the pull nose support core group 4. At this time, the upper wing piece 1 is taken out along the direction of the pull nose support core group 4, and then the buckle plate 7 is released. In this way, the disassembly of the slider is completed.

[0024] How it works

[0025] It should be noted that the utility model is a slider that is convenient for disassembly, assembly and replacement. When in use, when the slider needs to be installed, the lower wing piece 6 can be placed on the bottom side of the cloth belt with the chain teeth, and the lower engaging block 9 is pressed against the bottom side of the cloth belt. Then, the card slot 2 of the upper wing piece 1 is installed flush with the pull nose support core group 4. When the outer surface of the bottom end of the upper wing piece 1 touches the card block 5, the card block 5 is driven by pulling the buckle plate 7 so that the buckle plate 7 drives the card block 5 to retract along the direction of the pull nose support core group 4 until it retracts to the inner side of the pull nose support core group 4, and then the upper wing piece 1 continues to be moved along The pull nose support core group 4 is pressed downward until the outer surface of the bottom end of the upper wing piece 1 touches the limiting groove 8 and stops, then the buckle plate 7 is released, the blocking block 5 loses the pull of the buckle plate 7 and pops out, and the limiting groove 8 is matched to realize the precise engagement of the upper wing piece 1, thereby completing the limiting fixation of the upper wing piece 1 and the pull nose support core group 4, completing the assembly of the upper wing piece 1 and the lower wing piece 6, and realizing the rapid installation of the slider. After the installation of the slider is completed, by pressing the pressing block 13, the pressing block 13 is squeezed along the direction of the pull piece connecting lock 12, so that the slider is retracted. The positioning spring 15 is compressed, so that the pull-tab connecting lock 13 exposes the notch. At this time, the pressing block 13 is installed into the pull-nose groove 10 set on the inner side of the pull-nose support core group 4 along the notch. After the pressing block 13 is installed in the pull-nose groove 10, the pressing block 13 is released, and the pressure brought by the pressing block 13 is lost. The reset spring 15 is reset, driving the pressing block 13 to slide outward, thereby driving the pull-tab connecting lock 12 to reset again, thus completing the installation of the pull-tab 11. When disassembling, the pressing block 13 is pressed first, so that the pressing block 13 moves along the pull-nose groove 10. The pull tab 11 is then taken out from the pull nose groove 10, and then the pressing block 13 is released. This completes the removal of the pull tab, and then the buckle plate 7 is triggered to make the buckle plate 7 drive the positioning block 5 to shrink along the direction of the pull nose support core group 4 until it shrinks back to the inside of the pull nose support core group 4. At this time, the upper wing piece 1 is taken out along the direction of the pull nose support core group 4, and then the buckle plate 7 is released. This completes the removal of the slider.
