Detailed Implementation

[0019] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0020] Reference Figures 1-4As shown, this utility model provides a technical solution: a zipper head with a barb, including a zipper head base 1, a fixing frame 7 fixedly connected to the upper surface of the zipper head base 1, two guide grooves 5 opened on the upper surface of the zipper head base 1, guide blocks 6 slidably connected to the inner wall of the guide grooves 5, a zipper head connecting part 2 fixedly connected to the upper surface of the two guide blocks 6, a barb body 3 fixedly connected to the upper surface of the zipper head connecting part 2, a pull tab 4 movably connected to the inner wall of the barb body 3, a fixing block 8 fixedly connected to the lower surface of the zipper head connecting part 2, the fixing block 8 slidably connected to the inner wall of the fixing frame 7, slots 9 opened on both sides of the fixing block 8, and sliding grooves 10 opened on both sides of the inner wall of the fixing frame 7, two springs 11 fixedly connected to the inner wall of the sliding groove 10, a locking block 12 fixedly connected to one end of the two springs 11, the locking block 12 slidably connected to the inner wall of the sliding groove 10, and the size of the locking block 12 matching the size of the slot 9. Through the structural cooperation of guide groove 5, guide block 6, fixing frame 7, fixing block 8, etc. between the zipper head connecting part 2 and the zipper head base 1, as well as the locking and limiting of the locking block 12 and the locking groove 9, and with the elastic effect of spring 11, the connection between the zipper head connecting part 2 and the zipper head base 1 is stable and reliable during use, and can be easily disassembled and assembled when needed. This greatly facilitates the maintenance and replacement of the zipper head, and improves the flexibility and convenience of use. Two round rods 13 are slidably inserted in the fixing frame 7. The round rods 13 pass through the sliding groove 10. One end of the round rod 13 is fixedly connected to the locking block 12, and the other end of the round rod 13 is fixedly connected to the round block 14. By setting up the round rod 13 and the round block 14, the operator can pull the round block 14 to drive the round rod 13, thereby easily controlling the engagement or disengagement of the locking block 12 and the locking groove 9 without the need for special tools. This makes the disassembly and assembly of the zipper head connecting part 2 and the zipper head base 1 simpler and faster, significantly improving the convenience and efficiency of zipper head disassembly and assembly. The upper and lower surfaces of the locking block 12 are both arc-shaped, and the dimensions of the fixing block 8 and the inner wall of the fixing frame 7 are matched. The upper and lower surfaces of the locking block 12 are arc-shaped. During the process of the fixing block 8 and the fixing frame 7 cooperating, the guiding effect of the arc-shaped surface can be used to make the fixing block 8 press the locking block 12 to slide more smoothly, so that the connection and separation process of the pull head connecting part 2 and the pull head base 1 is smoother and more stable. The surface of the pull head base 1 is fixedly connected to the wax storage chamber 15, and the inner wall of the wax storage chamber 15 is slidably connected to the lubricating wax 19. A threaded rod 16 is rotatably inserted in the wax storage chamber 15. One end of the threaded rod 16 is fixedly connected to the rotating shaft 18. The arc surface of the threaded rod 16 is threadedly connected to the pressure plate 17, and the pressure plate 17 abuts against the upper surface of the lubricating wax 19.By setting up structures such as a wax storage chamber 15, a threaded rod 16, and a pressure plate 17, the rotation of the rotating shaft 18 can drive the threaded rod 16 to rotate, causing the pressure plate 17 to slide along the inner wall of the wax storage chamber 15. This continuously and stably applies pressure to the lubricating wax 19, allowing the lubricating wax 19 to provide lubrication to the zipper evenly and continuously, effectively improving the smoothness of the zipper sliding, reducing jamming, and enhancing the user experience and service life of the zipper. A fixing rod 20 is fixedly connected to the inner wall of the wax storage chamber 15, and the pressure plate 17 is slidably connected to the arc surface of the fixing rod 20. The fixed rod 20 is slidably connected to the pressure plate 17, providing guidance for the movement of the pressure plate 17. This ensures that the pressure plate 17 can slide stably and straight along the fixed rod 20 when driven by the threaded rod 16, preventing the pressure plate 17 from shifting or tilting. The arc surface of the rotating shaft 18 has several strip grooves 21, which are evenly distributed in a circumferential array on the arc surface of the rotating shaft 18. The surface of the pull tab 4 has several anti-slip protrusions. The strip grooves 21 on the arc surface of the rotating shaft 18 increase the friction between the hand and the rotating shaft 18, making it easier for the operator to apply force and less prone to slippage when rotating the rotating shaft 18 to adjust the pressure of the pressure plate 17, ensuring precise and efficient adjustment of the amount of lubricating wax 19 supplied. The anti-slip protrusions on the surface of the pull tab 4 improve the grip stability when the fingers pull the pull tab 4, preventing slippage during the pulling process.

[0021] Working principle: In terms of fixing, the guide block 6 on the lower surface of the zipper connector 2 is aligned with the guide groove 5 of the zipper base 1. The zipper connector 2 is pushed along the guide groove 5, causing the fixing block 8 below the zipper connector 2 to slide into the inner wall of the fixing frame 7 (the fixing block 8 and the inner wall of the fixing frame 7 are sized to ensure sliding fit). During the sliding process, the fixing block 8 presses the arc-shaped upper and lower surfaces of the locking block 12. The arc-shaped surface acts as a guide, pushing the locking block 12 to slide along the slide groove 10 to both sides and compressing the spring 11. When the fixing block 8 slides to the slot 9 and the locking block 12 are aligned, the spring 11 releases its elastic potential energy, pushing the locking block 12 to reset and embed into the slot 9, thus achieving the locking and fixing of the zipper connector 2 and the zipper base 1. At this time, the barb body 3 is stably installed with the zipper connector 2, and the zipper can be opened and closed by pulling the pull tab 4.

[0022] When it is necessary to disassemble the parts, pull the round blocks 14 outside the fixing frame 7 to both sides. The round blocks 14 drive the round rod 13 to slide along the fixing frame 7. The round rod 13 simultaneously pulls the locking block 12 to disengage from the locking groove 9 and compresses the spring 11. At this time, pull the pull head connecting part 2 upward along the guide groove 5. The guide block 6 slides away from the pull head connecting part 2 along the guide groove 5, and the disassembly of the pull head connecting part 2 and the pull head base 1 can be completed. This makes it easy to maintain and replace the barb body 3 or the pull head base 1 separately without the need for special tools.

[0023] Regarding the lubrication of the lubricating wax 19, rotating the shaft 18 outside the wax storage chamber 15 (the groove 21 on the arc surface of the shaft 18 increases hand friction and prevents slippage) causes the threaded rod 16 inside the wax storage chamber 15 to rotate. Since the pressure plate 17 is threadedly connected to the threaded rod 16 and slides in cooperation with the fixed rod 20 on the inner wall of the wax storage chamber 15, the fixed rod 20 provides guidance for the pressure plate 17 to prevent it from shifting. When the threaded rod 16 rotates, it drives the pressure plate 17 to slide up and down along the fixed rod 20. When the pressure plate 17 slides down, it continuously applies uniform pressure to the lubricating wax 19 inside the wax storage chamber 15, so that the lubricating wax 19 is in stable contact with the zipper chain. During the zipper sliding process, it provides continuous lubrication to the chain and chain teeth, reducing friction and jamming. When the lubricating wax 19 is consumed, rotating the shaft 18 in the opposite direction causes the pressure plate 17 to slide up, which opens the wax storage chamber 15 to replenish the lubricating wax 19 and ensures the stability of subsequent lubrication supply.

[0024] When pulling the zipper daily, the anti-slip protrusions on the surface of the pull tab 4 increase the grip friction between the fingers and the pull tab 4, preventing the fingers from slipping during the pulling process; when adjusting the pressure of the lubricating wax 19 to rotate the shaft 18, the groove 21 of the shaft 18 also improves the stability of the hand's force application, ensuring that each operation is convenient and reliable, and improving the overall user experience of the zipper head.

[0025] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
