Abstract
Description
Technical Field
[0001] This utility model relates to the field of zipper technology, and more specifically, to a quick-release zipper pull. Background Technology
[0002] Zippers, a common item in daily life, are often used as connectors for closing or separating items. Among them, quick-release zippers are one type of zipper, characterized by their ability to be quickly removed from items, thus improving the convenience of zippers.
[0003] Existing quick-release zippers typically close items by inserting the zipper bar into the zipper head and then pulling the zipper, causing the teeth on the zipper bar to mesh and close the items. However, sometimes the zipper head is not positioned correctly on the zipper bar, causing the zipper bar to misalign and jam. This can prevent the items from closing, and in severe cases, damage the zipper head, shortening the zipper's lifespan.
[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 quick-release zipper head, which solves the problem that when the zipper head is pulled, the zipper bar will become misaligned, making it impossible to close the item, and in severe cases, it will damage the entire zipper and affect the service life of the zipper.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a quick-release zipper head, comprising a zipper body with a pull tab, the zipper body comprising a top plate and a bottom plate, a fixed frame fixedly connected to the bottom of the top plate, a movable plate slidably connected within the fixed frame, the movable plate being fixedly connected to the bottom plate, a driving component for driving the movable plate to move along the inner side of the fixed frame being provided within the fixed frame, and the pull tab being connected to the top plate.
[0007] By adopting the above technical solution, when the zipper head is stuck on the zipper strip, the driving component drives the moving plate to move downward along the inside of the fixed frame. At the same time, the moving plate drives the bottom plate to move in the same direction. At this time, the distance between the top plate and the bottom plate increases and separates from the zipper strip. Then the zipper head is removed from the zipper strip and the item is closed again. This avoids the zipper head getting stuck on the zipper strip, prevents damage to the zipper head, and improves the service life of the zipper head.
[0008] The present invention is further configured such that: the driving component includes a moving rod; a through groove communicating with the outside is provided on the fixed frame; the moving rod and the through groove are slidably connected; a wedge block is fixedly connected to the moving plate; two limiting plates are fixedly connected to the side wall of the moving rod; the two limiting plates are in contact with the top of the top plate and the inner side wall of the fixed frame, respectively; and the moving rod and the inclined surface of the wedge block are connected by a connector.
[0009] By adopting the above technical solution, when it is necessary to drive the movable plate to move along the inner side of the fixed frame, the movable rod is driven to move along the through groove. At the same time, the movable rod is driven to move along the inclined surface of the wedge block through the connecting piece. At this time, since the two limiting plates are in contact with the top of the top plate and the inner side wall of the fixed frame respectively, the movable rod cannot move in the vertical direction. The wedge block moves downward due to the influence of its own inclined surface, and drives the bottom plate to move in the same direction through the movable plate, thereby increasing the distance between the bottom plate and the top plate. When it is necessary to restore the distance between the bottom plate and the top plate, it is only necessary to drive the movable rod back to its original position. Then, through the setting of the connecting piece, the wedge block, the movable plate and the bottom plate can be driven back to their original positions, thereby achieving the effect of driving the movable plate to move along the inner side of the fixed frame.
[0010] The present invention is further configured such that: the connecting member includes a rotating wheel rotatably connected to the bottom of the moving rod; a sliding groove for the rotating wheel to slide is provided on the inclined surface of the wedge block; annular grooves are provided on both sides of the rotating wheel; two limiting blocks are slidably connected to both sides of the sliding groove; and the limiting blocks and the annular grooves are slidably connected.
[0011] By adopting the above technical solution, when the moving rod moves along the through groove, the moving rod drives the rotating wheel to move along the sliding groove on the inclined surface of the wedge block, and drives the two limiting blocks to slide along the sliding groove. At the same time, it drives the wedge block to move up and down. By setting the two limiting blocks, the rotating wheel can be driven to move in the sliding groove while avoiding separation from the wedge block, thereby preventing the wedge block and the moving rod from separating from each other and avoiding affecting normal use.
[0012] The present invention is further configured such that: a limiting plate is slidably connected to the top plate, and a groove is provided on one side of the limiting plate to contact the moving rod; when the moving rod and the groove are in contact, the bottom plate and the fixed frame are in contact.
[0013] By adopting the above technical solution, when it is necessary to drive the moving rod to move along the through groove, the limiting piece is driven to move, and the groove and the moving rod are separated from each other. At this time, the moving rod is unrestricted and can move along the through groove. When the moving rod is driven back to its original position, the limiting piece is driven to move in the direction of the moving rod, and the groove and the moving rod are driven to contact each other. At this time, the moving rod is affected by the groove and cannot move. This achieves the effect of restricting the movement of the moving rod, avoiding the problem that the moving rod may move accidentally when the zipper head moves, causing the distance between the top plate and the bottom plate to change. This improves the stability between the moving rod and the through groove.
[0014] The present invention is further configured such that limiting plates are fixedly connected to both sides of the wedge block.
[0015] By adopting the above technical solution, the movement range of the rotating wheel on the wedge block can be limited, preventing the rotating wheel and the limiting block from separating from the wedge block during movement, thereby improving the fixing effect between the wedge block and the rotating wheel.
[0016] The present invention is further configured such that the fixed frame and the movable plate are connected by a number of springs, and when the springs are in their natural state, the base plate and the fixed frame are in contact with each other.
[0017] By adopting the above technical solution, when the distance between the top plate and the bottom plate is increased, the spring will undergo elastic deformation. The elastic potential energy released after the spring elastic deformation can drive the bottom plate back to its original position, thereby achieving the effect of automatically restoring the bottom plate, which is convenient for users to operate, and can also improve the stability between the bottom plate and the top plate.
[0018] The present invention is further configured such that: a fixing ring is fixedly connected to the top plate, there is a gap between the fixing ring and the through groove, and the pull tab and the fixing ring are slidably connected.
[0019] By adopting the above technical solution, the position of the pull tab on the top plate is limited, which makes it easier to move the moving rod and facilitates user operation.
[0020] In summary, this utility model has the following beneficial effects: when the zipper head is stuck on the zipper strip, the drive component drives the bottom plate to move downward. At this time, the distance between the top plate and the bottom plate increases and they separate from the zipper strip, thereby avoiding the zipper head from getting stuck on the zipper strip, preventing damage to the zipper head, and improving the service life of the zipper head.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0032] A quick-release zipper pull, such as Figures 1-7As shown, the zipper body includes a pull tab 1. The zipper body includes a top plate 2 and a bottom plate 3. A fixed frame 4 is fixedly connected to the bottom of the top plate 2. A movable plate 5 is slidably connected inside the fixed frame 4. The movable plate 5 and the bottom plate 3 are fixedly connected. The fixed frame 4 is provided with a drive assembly for driving the movable plate 5 to move along the inner side of the fixed frame 4. The pull tab 1 is connected to the top plate 2. When the zipper head is stuck on the zipper strip, the drive assembly drives the movable plate 5 to move downward along the inner side of the fixed frame 4. At the same time, the movable plate 5 drives the bottom plate 3 to move in the same direction. At this time, the distance between the top plate 2 and the bottom plate 3 increases and separates from the zipper strip. Then the zipper head is removed from the pull strip and the item is closed again. This avoids the zipper head getting stuck on the zipper strip, prevents damage to the zipper head, and improves the service life of the zipper head.
[0033] like Figures 1-5 As shown, the driving assembly includes a moving rod 6, a through groove 7 on the fixed frame 4 that communicates with the outside, the moving rod 6 and the through groove 7 are slidably connected, a wedge block 8 is fixedly connected to the moving plate 5, and two limiting pieces 9 are fixedly connected to the side wall of the moving rod 6. The two limiting pieces 9 are in contact with the top of the top plate 2 and the inner side wall of the fixed frame 4, respectively. The moving rod 6 and the inclined surface of the wedge block 8 are connected by a connector, which includes a rotating wheel 10 rotatably connected to the bottom of the moving rod 6. A sliding groove 11 is provided on the inclined surface of the wedge block 8 for the rotating wheel 10 to slide. Annular grooves 12 are provided on both sides of the rotating wheel 10, and two sliding grooves 12 are slidably connected to both sides of the sliding groove 11. Limiting block 13 is slidably connected to an annular groove 12. When it is necessary to drive the moving plate 5 to move along the inner side of the fixed frame 4, it drives the moving rod 6 to move along the through groove 7. At the same time, the moving rod 6 drives the rotating wheel 10 to move along the sliding groove 11 on the inclined surface of the wedge block 8. At this time, since the two limiting plates 9 are in contact with the top of the top plate 2 and the inner wall of the fixed frame 4 respectively, the moving rod 6 cannot move in the vertical direction, and the wedge block 8 moves downward due to the influence of its own inclined surface. At the same time, the moving plate 5 drives the bottom plate 3 to move in the same direction, thereby increasing the distance between the bottom plate 3 and the top plate 2.
[0034] When it is necessary to restore the distance between the bottom plate 3 and the top plate 2, simply drive the moving rod 6 back to its original position. Then, the rotating wheel 10 and the limiting block 13 will drive the wedge block 8, the moving plate 5, and the bottom plate 3 back to their original positions, thereby achieving the effect of driving the moving plate 5 to move along the inner side of the fixed frame 4. The two sides of the wedge block 8 are respectively fixedly connected to the limiting plates 16, which can limit the movement range of the rotating wheel 10 on the wedge block 8, prevent the rotating wheel 10 and the limiting block 13 from separating from the wedge block 8 during movement, and improve the fixing effect between the wedge block 8 and the rotating wheel 10.
[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 As shown, a limiting piece 14 is slidably connected to the top plate 2. A groove 15 is provided on one side of the limiting piece 14 to contact the moving rod 6. When the moving rod 6 and the groove 15 are in contact, the bottom plate 3 and the fixed frame 4 are in contact. When it is necessary to drive the moving rod 6 to move along the through groove 7, the limiting piece 14 is driven to move, and the groove 15 and the moving rod 6 are separated. At this time, the moving rod 6 is unrestricted and can move along the through groove 7. When the moving rod 6 is driven to return to its original position, the limiting piece 14 is driven to move in the direction of the moving rod 6, and the groove 15 and the moving rod 6 are in contact. At this time, the moving rod 6 is affected by the groove 15 and cannot move. This achieves the effect of restricting the movement of the moving rod 6, avoiding the problem that the moving rod 6 may move accidentally when the zipper head moves, causing the distance between the top plate 2 and the bottom plate 3 to change, and improving the stability between the moving rod 6 and the through groove 7.
[0036] like Figure 2 , Figure 6 As shown, the fixed frame 4 and the movable plate 5 are connected by several springs 17. When the springs 17 are in their natural state, the base plate 3 and the fixed frame 4 are in contact with each other. When the gap between the top plate 2 and the bottom increases, the springs 17 will undergo elastic deformation. The elastic potential energy released after the elastic deformation of the springs 17 can drive the base plate 3 back to its original position, thereby achieving the effect of automatically restoring the base plate 3, which is convenient for the user to operate.
[0037] like Figure 1 , Figure 2 , Figure 6 As shown, a fixing ring 18 is fixedly connected to the top plate 2. There is a gap between the fixing ring 18 and the through groove 7. The pull tab 1 and the fixing ring 18 are slidably connected, which limits the position of the pull tab 1 on the top plate 2, making it easier for the moving rod 6 to move and for the user to operate.
[0038] The following is how this utility model is used: When the zipper head is stuck on the zipper strip, the moving rod 6 is driven to move along the through groove 7. At the same time, the moving rod 6 drives the rotating wheel 10 to move along the sliding groove 11 on the inclined surface of the wedge block 8. At this time, since the two limiting pieces 9 are in contact with the top of the top plate 2 and the inner side wall of the fixed frame 4 respectively, the moving rod 6 cannot move in the vertical direction. The wedge block 8 moves downward due to the influence of its own inclined surface, and drives the bottom plate 3 to move in the same direction through the moving plate 5. At this time, the distance between the top plate 2 and the bottom plate 3 increases and separates from the zipper strip. Then the zipper head is removed from the zipper strip and the item is closed again. This avoids the zipper head getting stuck on the zipper strip, prevents damage to the zipper head, and improves the service life of the zipper head.
[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
