[0035] It should be noted that the directional words such as "left" and "right" below are defined based on the drawings in the specification.

[0036] The core of the present invention is to provide a detachable zipper head, which can realize the rapid detachment of the zipper head. Another core of the present invention is to provide a zipper including the detachable zipper head, which can realize the rapid detachment and replacement of the zipper head.

[0037] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A detachable zipper pull includes an upper zipper pull 1, a lower zipper pull 2 ​​and a zipper pull pin 3.

[0038] Specifically, the lower zipper slider 2 is pluggable and arranged on the upper zipper slider 1. By plugging and unplugging the lower zipper slider 2, the upper zipper slider 1 and the lower zipper slider 2 can be quickly separated and installed. The upper zipper slider 1 is provided with a zipper slider latch 3 that moves along its own width direction. The upper zipper slider 1 is also provided with a positioning latch 11 that extends along its own thickness direction. By providing the positioning latch 11, the zipper slider latch 3 can be effectively positioned to prevent the zipper slider latch 3 from falling off from the upper zipper slider 1. The positioning latch 11 is movably arranged in a limiting groove 31 of the zipper slider latch 3. The limiting groove 31 is provided with an elastic member 32 for limiting the position of the positioning latch 11. When installing the zipper slider When the zipper head is in the state of being moved, the zipper head pin 3 is moved along the width direction of the upper zipper head 1, so that the elastic member 32 contracts in the limiting groove 31, and the positioning pin 11 moves in the limiting groove 31 at the same time. The zipper head pin 3 is provided with a giving groove 33 for avoiding the lower zipper head 2. The giving groove 33 is made to make room for the lower zipper head 2 to be installed on the upper zipper head 1, so as to avoid the zipper head from interfering with the zipper head pin 3 during the installation and disassembly process. The lower zipper head 2 is provided with a connecting groove 221 which is connected with the zipper head pin 3. After the zipper head is installed, the connecting groove 221 of the lower zipper head 2 is connected and fixed with the zipper head pin 3 under the driving force of the restoring force of the elastic member 32.

[0039] When the zipper head needs to be removed, an external force is applied to the zipper head latch 3 so that the zipper head latch 3 can move to the clearance groove 33 and align with the clamping groove 221 of the lower zipper head 2, and the lower zipper head 2 is pulled out from the upper zipper head 1, and the upper zipper head 1 can be separated from the lower zipper head 2, thereby achieving the purpose of quickly removing the zipper head.

[0040] Among them, the material composition of all parts included in the upper zipper head 1, the lower zipper head 2 and the zipper head pin 3 can be selected from metals and metal alloys including but not limited to copper and copper alloys, zinc and zinc alloys, aluminum and aluminum alloys, steel and stainless steel alloys, powder metallurgy metals and titanium and titanium alloys; in addition, resins and polymer materials can also be selected including but not limited to aromatic nylon PA series, polyoxymethylene POM series, polyurethane TPU series, aromatic polyamide series and polypropylene PP series, and modified reinforced material series of all the above materials, and the modified materials include but are not limited to reinforced glass fiber, reinforced carbon fiber, etc.

[0041] The detachable zipper head arranged in the above manner can be quickly disassembled and assembled by only moving the zipper head latch 3.

[0042] In the above embodiment, the central axis of the zipper pull pin 3 extending along its own width direction divides the zipper pull pin 3 into two sides, one of which is provided with a clearance groove 33, which is a V-shaped groove with an opening toward one side of the zipper pull pin 3.

[0043] It should be noted that when installing the zipper head, the zipper head pin 3 is moved to the right to align the V-shaped groove with the lower zipper head 2. At the same time, the elastic member 32 in the limiting groove 31 is compressed, and the lower zipper head 2 is installed on the upper zipper head 1. The zipper head pin 3 is released so that the zipper head pin 3 is restored to its original position under the driving force of the restoring force of the elastic member 32, so that the engaging groove 221 of the lower zipper head 2 is engaged and fixed with the zipper head pin 3 to complete the installation of the zipper head; when the zipper head needs to be removed, the zipper head pin 3 is moved to the right to align the V-shaped groove with the engaging groove 221 of the lower zipper head 2, and the lower zipper head 2 is pulled out from the upper zipper head 1, and the upper zipper head 1 can be separated from the lower zipper head 2, thereby achieving the purpose of quickly removing the zipper head.

[0044] In the above situation, a limiting groove 31 is provided on the other side of the zipper pull pin 3 . The limiting groove 31 is a square through groove and extends along the length direction of the zipper pull pin 3 .

[0045] It is understandable that the square through-groove is provided to provide a space for installing the elastic member 32 , and the cooperation between the elastic member 32 and the positioning latch 11 enables the zipper head to be quickly installed.

[0046] Furthermore, the elastic member 32 is a spring, which is telescopically arranged along the length direction of the square through-groove. A cylindrical hole for installing the spring is provided on one side wall of the square through-groove close to the V-groove. The spring is used to provide a pre-tightening force to move the positioning pin 11 in a direction away from the V-groove.

[0047] It should be noted that the positioning latch 11 is effectively pressed by the pre-tightening force of the spring, and the zipper head latch 3 is driven to move leftward synchronously as a whole by the restoring force of the spring.

[0048] Among them, in addition to the spring-shaped object that can play the role of expansion and contraction, the elastic member 32 can also be a compression elastic rod, a compression elastic rope with elastic expansion and contraction function, or a hydraulic device with programmable compression control.

[0049] Please refer to Figure 5 、 Figure 6 、 Figure 7 and Figure 8 The upper zipper head 1 includes an upper cover plate 12, which is provided with a pin hole 121 extending along its width direction. The zipper head pin 3 is movably provided in the pin hole 121. The upper cover plate 12 is also provided with a pin groove 122 extending along its thickness direction. The opening of the pin groove 122 faces the upper end surface of the upper cover plate 12. The positioning pin 11 is pluggable and provided in the pin groove 122. The pin hole 121 is connected to the pin groove 122, and the bottom of the pin groove 122 is lower than the hole wall of the pin hole 121. The pin groove 122 is provided on the side close to the upper cover plate 12 and corresponds to the square through groove.

[0050] It can be understood that the upper cover 12 has a through pin hole 121, a core groove 125 and a pin groove 122. When assembling the zipper head pin 3 and the upper zipper head 1, the zipper head pin 3 can be fully inserted horizontally into the pin hole 121 and completely fit with the inside of the pin hole 121. At this time, the spring is adjusted to a compressed state, and the opposite side of the square through-groove where the spring is installed is flush with the right side of the pin groove 122. At this time, the positioning pin 11 is inserted into the pin groove 122, so that the positioning pin 11 passes through the square through-groove, so that the bottom end of the positioning pin 11 fits with the bottom of the pin groove 122. At this time, the spring is adjusted to a relaxed state, and the spring automatically supports the positioning pin 11 in the square through-groove.

[0051] The positioning pin 11 can be fully inserted into the bottom of the pin slot 122 and fits perfectly with the bottom. When the positioning pin 11 is fully inserted into the bottom of the pin slot 122, the top of the positioning pin 11 and the top surface of the pin slot 122 are completely flush with each other. At this point, the positioning pin 11 is secured to the upper cover 12 through other processes. Furthermore, when the positioning pin 11 is inserted into the bottom of the pin slot 122, the positioning pin 11 completely passes through the pin hole 121. The positioning pin 11 can also completely pass through the square through-slot.

[0052] Based on the above embodiment, a raised lower rib 123 extending to the tail of the upper cover plate 12 is provided in the middle of the lower end surface of the upper cover plate 12, and the end of the raised lower rib 123 away from the tail of the upper cover plate 12 is a semicircular structure, and waist baffles 124 are provided on both sides of the lower end surface of the upper cover plate 12.

[0053] It should be noted that the raised lower rib 123 and the waist baffle 124 are auxiliary zipper engaging parts. The top of the raised lower rib 123, that is, the end close to the core groove 125, is a semicircular structure. When the zipper teeth are engaged, it plays a role of clamping the zipper teeth. When the zipper is engaged, the waist baffle 124 plays a limiting role on both sides of the zipper teeth, so that the zipper teeth engage with each other.

[0054] In the above embodiment, the lower zipper head 2 includes a lower base plate 21, and the lower base plate 21 is provided with a core 22 extending in a direction perpendicular to the lower base plate 21. The core 22 is located at the head of the lower base plate 21, and the lower end surface of the upper cover plate 12 is provided with a corresponding core groove 125. The core 22 is pluggable and arranged in the core groove 125, and the core 22 is fitted with the core groove 125.

[0055] It can be understood that the V-shaped groove can be completely fitted with the V-shaped position below the core mold 22, the core mold 22 is inserted into the bottom of the core mold groove 125, and the core mold 22 is completely fitted with the core mold groove 125. The core mold 22, the core mold groove 125 and the V-shaped groove are the same size. The zipper head pin 3 is inserted into the through pin hole 121 and the V-shaped groove is completely overlapped with the lower part of the core mold groove 125. The core mold 22 can be inserted into the V-shaped groove and the core mold groove 125 in turn, and the three are completely overlapped.

[0056] As a preferred embodiment, a snap-fit ​​groove 221 is provided on the mold core 22 , and the opening of the snap-fit ​​groove 221 faces the rear end of the lower base plate 21 .

[0057] It should be noted that the mold core 22 and the mold core groove 125 are mutually fitting parts. When the mold core 22 is fully inserted into the mold core groove 125, the top surface of the mold core 22 is completely in contact with the bottom of the mold core groove 125, and the inside of the mold core groove 125 is completely fitted with the mold core 22. At this time, the snap-fit ​​groove 221 and the through-type pin hole 121 are completely overlapped, and the zipper head pin 3 can completely pass through the snap-fit ​​groove 221 and the through-type pin hole 121.

[0058] In the above case, the length of the zipper slider pin 3 is greater than the width of the upper zipper slider 1 .

[0059] It is understandable that the length of the zipper pull pin 3 is greater than the length of the through-type pin hole 121 . When the zipper pull pin 3 completely passes through the through-type pin hole 121 , a portion of the zipper pull pin 3 still does not enter the through-type pin hole 121 .

[0060] In summary, the detachable zipper head provided by the present invention can be easily and quickly disassembled by using fewer parts and reasonable design.

[0061] In addition to the detachable zipper heads disclosed in the above embodiments, the present invention also provides a zipper including the above detachable zipper heads. For the structures of other parts of the zipper, please refer to the prior art and will not be described in detail herein.
