Description

Technical Field

[0001] This utility model relates to the field of zipper technology, and more specifically, to a nylon zipper. Background Technology

[0002] Nylon zippers are typically made by heating and pressing nylon monofilaments. They are lightweight, wear-resistant, and corrosion-resistant, and are commonly used in the clothing, bag, and tent industries.

[0003] In order to improve the sealing performance and ease of use, existing nylon zippers are usually manufactured with the zipper head as an integral structure. However, when the zipper head is damaged, it is difficult for users to repair it, which affects the service life of the zipper head in the nylon zipper.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a nylon zipper that solves the problem that when the zipper head is damaged, it is difficult for the user to repair the zipper head, which affects the service life of the nylon zipper head.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a nylon zipper, including a zipper head body with a pull tab, the zipper head body including a bottom plate and a top plate, a pull tab fixedly connected to the bottom plate, a fixing block fixedly connected to the pull tab, an installation groove for inserting the fixing block on the top plate, the fixing block and the installation groove being interlocked by a snap-fit ​​component, and the pull tab and the top plate being detachably connected.

[0007] By adopting the above technical solution, when the pull tab in the nylon zipper is damaged, the locking component drives the locking between the fixing block and the mounting groove to be released. Then, a pulling force is applied to the top plate to drive the fixing block and the mounting groove to separate from each other. The pull tab is then removed from the top plate, and the damaged part is replaced or repaired. After the damaged part is replaced or repaired, the pull tab and the top plate are installed together. Then, the fixing block is inserted into the mounting groove, and the fixing block and the mounting groove are fixed together by the locking component. This achieves the effect of disassembling and installing the zipper head, which facilitates the repair of the zipper head and improves the service life of the zipper head.

[0008] The present invention is further configured such that: the snap-fit ​​assembly includes a movable block slidably connected in the mounting groove; a through groove for the movable block to be inserted is provided on one side of the fixed block; a movable rod is fixedly connected to the side of the movable block away from the fixed block; the movable rod passes through the top plate to the outside and is slidably connected to the top plate; and a limiting groove for the movable block to slide is provided on the side wall of the mounting groove.

[0009] By adopting the above technical solution, when it is necessary to remove the fixing block from the mounting slot, the moving rod is pulled, causing it to move outward. At the same time, the moving rod drives the moving block to move in the same direction and separate from the through slot. At this time, the fixing block and the mounting slot are no longer restricted by the moving rod, thus achieving the effect of removing the moving block from the mounting slot. When it is necessary to install the fixing block and the mounting slot together, the fixing block is inserted into the mounting slot, and then the moving rod is pushed, causing it to move towards the fixing block. At the same time, the moving rod drives the moving block to insert into the through slot. At this time, the fixing block and the mounting slot are restricted by the moving rod, making it impossible for the fixing block and the mounting slot to separate from each other, thus achieving the effect of driving the fixing block and the mounting slot to install together.

[0010] The present invention is further configured such that: two limiting plates are fixedly connected to the end of the moving rod away from the moving block, and a paddle that moves up and down is slidably connected between the two limiting plates. The paddle has a sliding groove for the moving rod to slide, and the paddle is arranged in an "L" shape. A locking block is fixedly connected to the top plate, and a locking groove for the locking block to engage is provided on the paddle. When the locking block and the locking groove engage with each other, the paddle and the top plate are in contact with each other, and at this time the moving block is inserted into the through groove.

[0011] By adopting the above technical solution, when the moving rod is driven to move outward, a pulling force is applied to the paddle, causing it to move upward and disengaging the locking block and the slot. The paddle is then driven to move, simultaneously moving the moving rod outward. When the fixing block and the mounting slot are fixed together, the paddle is driven to move back to its original position, and the moving rod drives the moving block into the through slot. Pressure is then applied to the paddle, causing it to contact the top plate and engaging the locking block and the slot. At this point, the paddle is restricted by the locking block and the slot, preventing it from moving, and the moving block also cannot move. This improves the fixing effect of the moving block in the through slot. The paddle also facilitates the movement of the moving rod, making it easier for the user to operate. The two limiting plates prevent separation between the paddle and the moving rod, avoiding any impact on the normal use of the paddle.

[0012] The present invention is further configured such that: a connecting block is fixedly connected to the top plate, a connecting rod is slidably connected to the top plate, a limiting groove is provided on the connecting block for the connecting rod to engage, and the pull tab is slidably connected to the connecting rod and the connecting block respectively.

[0013] By adopting the above technical solution, when it is necessary to install the pull tab and the top plate together, the tension of the connecting rod bracket drives the connecting rod to move on the top plate and separate from the limiting groove. Then, the pull tab is placed on the connecting rod or connecting block, and at the same time, the connecting rod is driven to insert into the limiting groove and return to its original position. At this time, the pull tab cannot be separated from the connecting rod and connecting block bracket, thereby achieving the effect of installing the pull tab and the top plate together.

[0014] The present invention is further configured such that: an arc-shaped groove is provided on the paddle; when the locking block and the locking groove are engaged with each other, the arc-shaped groove and the connecting rod are in contact with each other, and at this time the connecting rod and the limiting groove are engaged with each other.

[0015] By adopting the above technical solution, when the card block and the card slot are engaged with each other, the arc-shaped groove and the connecting rod can be driven to abut against each other, thereby improving the fixing effect between the connecting rod and the connecting block and preventing the connecting block from separating from the limiting groove.

[0016] The present invention is further configured such that the moving block and the limiting groove are connected by a spring. When the spring is in its natural state, the moving block is inserted into the through groove, and at this time the connecting rod and the limiting groove are engaged with each other.

[0017] By adopting the above technical solution, when installing the zipper head, the spring setting can automatically reset the moving block and the lever, making it easier for the user to operate. At the same time, it can also improve the fixing effect of the bottom plate, top plate and the zipper lever after installation.

[0018] The present invention is further configured such that: a limiting rod is fixedly connected to the paddle near the arc-shaped groove, and the limiting rod and the connecting rod are in contact with each other.

[0019] By adopting the above technical solution, the connecting rod can be moved in the same direction while the paddle moves, reducing the number of steps for users to install and disassemble, and making it easier for users to operate.

[0020] In summary, this utility model has the following beneficial effects: When the pull tab in a nylon zipper is damaged, the locking component drives the locking between the fixing block and the mounting groove to be released, thereby separating the fixing block and the mounting groove from each other. Then, the pull tab is removed from the top plate, and the damaged part is replaced or repaired. After the damaged part is replaced or repaired, the pull tab and the top plate are installed together, and then the fixing block is inserted into the mounting groove. The locking component is used to fix the fixing block and the mounting groove together, thereby achieving the effect of disassembling and installing the zipper head, facilitating the repair of the zipper head, and improving the service life of the zipper head.

[0029] A type of nylon zipper, such as Figures 1-4As shown, the zipper head body includes a pull tab 1. The zipper head body includes a base plate 2 and a top plate 3. A pull tab 4 is fixedly connected to the base plate 2, and a fixing block 5 is fixedly connected to the pull tab 4. The top plate 3 has an installation groove 6 for inserting the fixing block 5. The fixing block 5 and the installation groove 6 are interlocked by a snap-fit ​​assembly. The pull tab 1 and the top plate 3 are detachably connected. When the pull tab 1 in the nylon zipper is damaged, the snap-fit ​​assembly drives the fixing block 5 and the installation groove 6 to disengage. Then, a pulling force is applied to the top plate 3 to drive the fixing block 5 and the installation groove 6 to separate. The pull tab 1 is then removed from the top plate 3, and the damaged part is replaced or repaired. After the damaged part is replaced or repaired, the pull tab 1 and the top plate 3 are installed together. Then, the fixing block 5 is inserted into the installation groove 6, and the fixing block 5 and the installation groove 6 are fixed together by the snap-fit ​​assembly. This achieves the effect of disassembling and installing the zipper head, facilitating the repair of the zipper head and improving its service life.

[0030] like Figures 2-4 As shown, the snap-fit ​​assembly includes a movable block 7 slidably connected within the mounting groove 6. A through groove 8 is provided on one side of the fixed block 5 for the movable block 7 to be inserted. A movable rod 9 is fixedly connected to the side of the movable block 7 away from the fixed block 5. The movable rod 9 passes through the top plate 3 to the outside and is slidably connected to the top plate 3. A limiting groove 21 is provided on the side wall of the mounting groove 6 for the movable block 7 to slide. When it is necessary to remove the fixed block 5 from the mounting groove 6, the movable rod 9 is pulled, causing it to move outwards. Simultaneously, the movable rod 9 drives the movable block 7 to move in the same direction, interacting with the through groove 8. When the fixed block 5 and the mounting slot 6 are separated, the moving block 7 is no longer restrained between them, thus allowing the moving block 7 to be removed from the mounting slot 6. When it is necessary to install the fixed block 5 and the mounting slot 6 together, the fixed block 5 is inserted into the mounting slot 6, and then the moving rod 9 is pushed to move towards the fixed block 5, while simultaneously driving the moving block 7 into the through slot 8. At this time, the fixed block 5 and the mounting slot 6 are restrained by the moving block 7, making it impossible for the fixed block 5 and the mounting slot 6 to separate from each other, thus achieving the effect of installing the fixed block 5 and the mounting slot 6 together.

[0031] like Figures 1-4As shown, two limiting plates 10 are fixedly connected to the end of the moving rod 9 away from the moving block 7. A movable lever 11 is slidably connected between the two limiting plates 10. The lever 11 has a groove 12 for the moving rod 9 to slide on. The lever 11 is L-shaped. A locking block 13 is fixedly connected to the top plate 3. The lever 11 has a slot 14 for the locking block 13 to engage. When the locking block 13 and the slot 14 engage with each other, the lever 11 and the top plate 3 are in contact. At this time, the moving block 7 is inserted into the through slot 8. When the moving rod 9 is driven to move outward, a pulling force is applied to the lever 11, causing the lever 11 to move upward and causing the locking block 13 and the slot 14 to disengage. Then the lever 11 is driven to move, simultaneously driving the moving rod 9 outward. When movement occurs, when the fixing block 5 and the mounting groove 6 are fixed together, the paddle 11 is driven to move back to its original position, and the moving rod 9 drives the moving block 7 to insert into the through groove 8. Then, pressure is applied to the paddle 11, causing the paddle 11 and the top plate 3 to contact each other, and causing the locking block 13 and the locking groove 14 to engage with each other. At this time, the paddle 11 is restricted by the locking block 13 and the locking groove 14 and cannot move, and the moving block 7 also cannot move. This improves the fixing effect of the moving block 7 in the through groove 8. At the same time, the paddle 11 also makes it easier to drive the moving rod 9 to move, which is convenient for the user to operate. The two limiting pieces 10 prevent the paddle 11 and the moving rod 9 from separating, thus avoiding affecting the normal use of the paddle 11.

[0032] like Figure 1 and Figure 2 As shown, a connecting block 15 is fixedly connected to the top plate 3, and a connecting rod 16 is slidably connected to the top plate 3. A limiting groove 17 is provided on the connecting block 15 for the connecting rod 16 to engage. A pull tab 1 is slidably connected to both the connecting rod 16 and the connecting block 15. When the pull tab 1 and the top plate 3 need to be installed together, a pulling force is applied to the support of the connecting rod 16, causing the connecting rod 16 to move on the top plate 3 and separate from the limiting groove 17. Then, the pull tab 1 is placed onto the connecting rod 16 or the connecting block 15, simultaneously driving the connecting rod 16 to insert into the limiting groove 17 and return to its original position. At this time, the pull tab... 1. It is impossible to separate from the connecting rod 16 and the connecting block 15 bracket, so as to achieve the effect of installing the pull piece 1 and the top plate 3 together. The lever 11 has an arc groove 18. When the locking block 13 and the locking groove 14 are locked together, the arc groove 18 and the connecting rod 16 are in contact with each other. At this time, the connecting rod 16 and the limiting groove 17 are locked together. When the locking block 13 and the locking groove 14 are locked together, the arc groove 18 and the connecting rod 16 can be driven to abut against each other, which improves the fixing effect between the connecting rod 16 and the connecting block 15 and prevents the connecting block 15 from separating from the limiting groove 17.

[0033] like Figures 2-4As shown, the movable block 7 and the limiting groove 21 are connected by a spring 19. When the spring 19 is in its natural state, the movable block 7 is inserted into the through groove 8, and at this time the connecting rod 16 and the limiting groove 17 are engaged with each other. When installing the zipper head, the spring 19 can automatically reset the movable block 7 and the lever 11, making it easier for the user to operate. It can also improve the fixing effect of the bottom plate 2, the top plate 3 and the lever 1 after installation.

[0034] like Figures 1-3 As shown, a limiting rod 20 is fixedly connected to the paddle 11 near the arc-shaped groove 18. The limiting rod 20 and the connecting rod 16 are in contact with each other. When the paddle 11 moves, it can also drive the connecting rod 16 to move in the same direction, reducing the number of steps for the user to install and disassemble, and making it easier for the user to operate.

[0035] The working principle of this utility model is as follows: When the pull tab 1 in the nylon zipper is damaged, the moving rod 9 is pulled, causing it to move in the outward direction. At the same time, the moving rod 9 drives the moving block 7 to move in the same direction and separate from the through groove 8. At this time, the fixed block 5 and the mounting groove 6 are no longer restricted by the moving block 7. Then, a pulling force is applied to the top plate 3, causing the fixed block 5 and the mounting groove 6 to separate from each other. Then, the pull tab 1 is removed from the top plate 3, and the damaged part is replaced or repaired. After the damaged part is replaced or repaired, the pull tab 1 and the top plate 3 are installed together. Then, the fixed block 5 is inserted into the mounting groove 6. Then, the moving rod 9 is pushed, causing it to move towards the fixed block 5. At the same time, the moving block 7 is inserted into the through groove 8. At this time, the fixed block 5 and the mounting groove 6 are restricted by the moving block 7, making it impossible for the fixed block 5 and the mounting groove 6 to separate from each other. This achieves the effect of disassembling and installing the zipper head, facilitating the repair of the zipper head and improving its service life.
