Description

Technical Field

[0001] This utility model relates to the field of zipper head technology, specifically a zipper with an anti-jamming mechanism. Background Technology

[0002] A zipper is a fastener that allows for repeated and rapid connection and disconnection. It consists of two toothed chain straps, a zipper pull, and top and bottom stops. The teeth of the chain straps engage or disengage through the operation of the zipper pull, thus enabling the opening and closing of items. Zippers are widely used in clothing, bags, tents, and many other items.

[0003] The zipper pull is the core component of a zipper, playing a crucial role. It is usually made of metal, plastic, or nylon, and comes in various shapes, most commonly square or rectangular. The zipper pull has a clever internal structure with special locking teeth. When the zipper pull is pulled, these teeth precisely guide the teeth of the zipper belt to engage or disengage, controlling the opening and closing of the zipper.

[0004] According to the patent application "A Zipper with an Anti-Jaw-Getting Mechanism (Publication No.: CN 221997098 U; Application No.: 202420781710.1)", although the application uses a combing plate and a limiting plate to limit the protective fabric and prevent it from getting stuck between the zipper teeth, this method has limitations. When thick, hard, or irregular foreign objects enter between the zipper teeth, the combing plate and the limiting plate cannot effectively handle them, and jamming is still likely to occur. Moreover, once jamming occurs, since the zipper pull is not detachable, users cannot solve the problem themselves and can only rely on external tools or seek professional repair, which is cumbersome and may damage the zipper. In terms of component repair and replacement, in existing cases, if the zipper pull suffers wear and deformation due to long-term use, since the zipper pull is a whole structure, the damaged part cannot be replaced separately. Users often have to replace the entire zipper, which is both wasteful of resources and increases costs. Utility Model Content

[0005] The purpose of this invention is to provide a zipper with an anti-jamming mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a zipper with an anti-jamming mechanism, comprising an upper zipper head, a lower zipper head at the bottom of the upper zipper head, a pull tab at the top of the upper zipper head, a splicing mechanism inside the upper zipper head, and a fixing mechanism at the front side of the splicing mechanism.

[0007] The splicing mechanism includes a splicing component and a snap-fit ​​component. The splicing component is disposed inside the upper and lower pull heads, and the snap-fit ​​component is disposed inside the splicing component.

[0008] The fixing mechanism includes a positioning component and a protective component. The positioning component is disposed inside the front side of the splicing component, and the protective component is disposed in front of the positioning component.

[0009] Preferably, the splicing component includes a splicing block, which is fixedly connected to the bottom of the upper half of the pull head. A splicing seat is provided at the bottom of the splicing block, and the splicing seat is fixedly connected to the top of the lower half of the pull head.

[0010] Preferably, the snap-fit ​​assembly includes a snap-fit ​​cylinder, which is fixedly connected to the top of the splicing base and snaps into the bottom of the splicing block. A snap-fit ​​block is provided on the outside of the snap-fit ​​cylinder, which is fixedly connected to the top of the splicing base and snaps into the bottom of the splicing block.

[0011] Preferably, the positioning component includes a fixing seat, which is fixedly connected to the front side of the splicing block. A bolt is snapped into the front side of the fixing seat, and the bolt is threaded into the inner ring of the clamping sleeve and snapped into the splicing block.

[0012] Preferably, the protective component includes a hemispherical sleeve, which is fitted onto the front side of the bolt, and a threaded tube is fixedly connected to the rear side of the hemispherical sleeve, which is threadedly connected to the front side of the fixing seat.

[0013] Compared with the prior art, this utility model provides a zipper with an anti-jamming mechanism, which has the following beneficial effects:

[0014] 1. This zipper with an anti-jamming mechanism uses a splicing mechanism to connect the upper and lower zipper heads. If jamming occurs, the upper and lower zipper heads can be disassembled to release the jam. The detachable upper and lower zipper heads also allow for easy replacement of damaged or deformed parts, preventing the zipper from becoming unusable due to structural deformation and increasing the lifespan of all components.

[0015] 2. This zipper with an anti-jamming mechanism, through its fixed mechanism, allows for easy fixation of the upper and lower zipper heads after the upper and lower zipper heads are joined. Simply rotate the bolt to the front of the fixing base, and the bolt thread will engage with the clip and the joining block, thus securing the upper and lower zipper heads. This allows workers to quickly and easily assemble and disassemble the upper and lower zipper heads by simply rotating the bolt. The semi-spherical sleeve protects the bolt, preventing it from rotating under external force during use and ensuring the stability of the upper and lower zipper heads after installation.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] This utility model provides a technical solution:

[0025] Example 1

[0026] Combination Figures 1 to 4 A zipper with an anti-jamming mechanism includes an upper zipper pull 3, a lower zipper pull 31 at the bottom of the upper zipper pull 3, a pull tab 4 at the top of the upper zipper pull 3, a splicing mechanism 1 inside the upper zipper pull 3, and a fixing mechanism 2 at the front of the splicing mechanism 1.

[0027] The splicing mechanism 1 includes a splicing component 11 and a snap-fit ​​component 12. The splicing component 11 is disposed inside the upper half pull head 3 and the lower half pull head 31, and the snap-fit ​​component 12 is disposed inside the splicing component 11.

[0028] The splicing component 11 includes a splicing block 1101, which is fixedly connected to the bottom of the upper half pull head 3. A splicing seat 1102 is provided at the bottom of the splicing block 1101, and the splicing seat 1102 is fixedly connected to the top of the lower half pull head 31. The snap-fit ​​component 12 includes a snap-fit ​​cylinder 1201, which is fixedly connected to the top of the splicing seat 1102 and snaps into the bottom of the splicing block 1101. A snap-fit ​​block 1202 is provided on the outside of the snap-fit ​​cylinder 1201, which is fixedly connected to the top of the splicing seat 1102 and snaps into the bottom of the splicing block 1101.

[0029] Furthermore, the upper pull tab 3 and the lower pull tab 31 are assembled together, so that if the pull tab gets stuck during use, the upper pull tab 3 and the lower pull tab 31 can be directly disassembled to release the blockage. At the same time, the detachable upper pull tab 3 and the lower pull tab 31 allow for direct replacement of the damaged or deformed upper pull tab 3 or lower pull tab 31 during use, so that the pull tab will not become unusable due to deformation of part of the structure, thus increasing the service life of each component of the pull tab.

[0030] Example 2

[0031] See Figures 1 to 4 Furthermore, based on Embodiment 1, the fixing mechanism 2 includes a positioning component 21 and a protective component 22. The positioning component 21 is disposed inside the front side of the splicing component 11, and the protective component 22 is disposed in front of the positioning component 21.

[0032] The positioning component 21 includes a fixing seat 2101, which is fixedly connected to the front side of the splicing block 1101. A bolt 2102 is snapped into the front side of the fixing seat 2101. The bolt 2102 is threadedly connected to the inner ring of the retainer 1201 and snapped into the splicing block 1101. The protective component 22 includes a hemispherical sleeve 2201, which is sleeved on the front side of the bolt 2102. A threaded tube 2202 is fixedly connected to the rear side of the hemispherical sleeve 2201 and is threadedly connected to the front side of the fixing seat 2101.

[0033] Furthermore: After the upper half of the pull head 3 and the lower half of the pull head 31 are spliced, simply rotate the bolt 2102 to the front side of the fixing seat 2101. This allows the bolt 2102 to be threaded into the clamping sleeve 1201 and simultaneously clamped into the splicing block 1101, thus fixing the upper half of the pull head 3 and the lower half of the pull head 31. In other words, the operator only needs to rotate the bolt 2102 to complete the disassembly and assembly of the upper half of the pull head 3 and the lower half of the pull head 31. This allows the operator to quickly complete the disassembly and assembly of the upper half of the pull head 3 and the lower half of the pull head 31. The operation is simple and convenient for the operator to use. The hemispherical sleeve 2201 is fitted onto the outside of the bolt 2102 to protect the bolt 2102. This prevents the bolt 2102 from rotating under external force when the pull head is in use, ensuring the stability of the upper half of the pull head 3 and the lower half of the pull head 31 after installation.

[0034] In actual operation, when this device is used and it is necessary to disassemble the upper pull head 3 and the lower pull head 31, the operator first uses a tool to rotate the hemispherical sleeve 2201. The rotation of the hemispherical sleeve 2201 drives the threaded tube 2202 to rotate. The threaded tube 2202 rotates and moves forward within the fixed seat 2101. The forward movement of the threaded tube 2202 disengages it from the fixed seat 2101. Then, the operator rotates the bolt 2102. The bolt 2102 rotates and moves forward within the inner ring of the clamp 1201. The forward movement of the bolt 2102 disengages it from the clamp 1201 and the splicing block 1101. At this time, the bolt 2102 releases the positioning of the clamp 1201 and the splicing block 1101. After that, the operator can move the upper pull head 3 upward while moving the lower pull head 31 downward, so that the clamp 1201 and the clamp 1202 are disengaged from the splicing block 1101. At this time, the disassembly of the upper pull head 3 and the lower pull head 31 is completed.

[0035] When installing the upper pull head 3 and the lower pull head 31, the worker first places the lower pull head 31 below the upper pull head 3, aligning the splicing block 1101 and the splicing seat 1102. Then, the lower pull head 31 is moved upwards, causing the clamping cylinder 1201 and the clamping block 1202 to engage with the bottom of the splicing block 1101 until the bottom of the splicing block 1101 is in contact with the top of the splicing seat 1102. Then, the bolt 2102 is inserted into the front of the fixing seat 2101 until it contacts the clamping cylinder 1201. After that, the bolt 2102 is rotated, causing the inner ring of the clamping cylinder 1201 to move backwards. 102 moves backward through the clamping sleeve 1201 and engages with the splicing block 1101 until the bolt 2102 can no longer rotate. At this point, the splicing process between the upper pull head 3 and the lower pull head 31 is completed. Finally, the hemispherical sleeve 2201 is placed in front of the bolt 2102 and rotated. The rotation of the hemispherical sleeve 2201 drives the threaded tube 2202 to rotate. The rotation of the threaded tube 2202 and the fixed seat 2101 move forward, inward and backward until the hemispherical sleeve 2201 can no longer rotate. At this point, the installation of the hemispherical sleeve 2201 is completed, and the splicing process between the upper pull head 3 and the lower pull head 31 is completed.
