Description

Technical Field

[0001] This utility model relates to the field of zipper technology, and in particular to a smooth zipper with a strong connection. Background Technology

[0002] Zippers are connectors that use continuously arranged teeth to join or separate items. They are now widely used in clothing, bags, tents, and other products.

[0003] In related technologies, a utility model patent with patent publication number CN212368477U discloses an injection-molded zipper. This utility model discloses an injection-molded zipper that includes fabric strips on two sides, and front and back zipper teeth on the two sides of the fabric strips respectively. The neck of the back zipper teeth tapers inward, and the head of the back zipper teeth is divided into a lower half and an upper half. The lower half extends along the neck of the zipper teeth to the center line of the zipper teeth, and the upper half is located on the other side of the center line of the zipper teeth and is semi-circular with the lower half exposed on both sides of the bottom end.

[0004] Based on the aforementioned prior art, and in conjunction with related technologies, the inventor discovered in practical applications that this utility model only simply increases the smoothness of the zipper. During the pulling process, the resistance and friction between the zipper teeth and the zipper pull are relatively large, which easily causes the zipper pull to be difficult to pull. Furthermore, the zipper teeth below the zipper pull are not fixed, causing the zipper teeth to not lock together and thus break apart, making the zipper not securely locked. Moreover, the zipper pull cannot be suspended and locked at any time during the pulling process, so when the zipper needs to be pulled halfway, the zipper pull may slip to the bottom during the movement, affecting its use. Therefore, this utility model cannot adapt to various situations. Thus, it is very necessary to provide a zipper with a firm connection that can be suspended at any time and with less friction between the zipper pull and the zipper teeth. Utility Model Content

[0005] To address the problem of high friction between the zipper pull and the zipper teeth in existing technologies, this invention provides a smooth zipper with a secure connection. The present invention provides a smooth zipper with a strong connection, which adopts the following technical solution: A smooth-running zipper with a secure connection includes zipper fabric. Two zipper fabrics have teeth on their inner sides, which interlock. A top pull head is slidably connected to the top of each tooth, and a bottom pull head is slidably connected to the bottom of each tooth. A connecting block is welded to the bottom of the top pull head, and the connecting block is welded to the bottom pull head. A smooth-running component is provided inside the connecting block, and a secure component is provided inside the top pull head.

[0006] Furthermore, the smoothing component includes a lubricating roller, a lifting block, a cover plate, and roller grooves. Two roller grooves are formed on the side wall of the connecting block. One end of the lubricating roller is installed on the side wall of the two roller grooves through a rotating shaft. The other end of the lubricating roller is connected to the lifting block through the rotating shaft. The top of the top pull head is rotatably connected to the cover plate.

[0007] Furthermore, the cover plate sidewall is provided with a locking protrusion, and the connecting block sidewall is provided with a locking groove that cooperates with the locking protrusion. When the locking protrusion and the top pull head sidewall are in contact with each other, the locking protrusion and the locking groove are locked together.

[0008] Furthermore, the sturdy assembly includes a first sliding rod, a second sliding rod, a fixed spring, a first connecting plate, a second connecting plate, a push block, a first sliding groove, a second sliding groove, and a sliding unit. The outer wall of the top pull head has a first sliding groove, and a first sliding rod is slidably connected to the side wall of the first sliding groove. Two push blocks are integrally formed on the side wall of the first sliding rod, and a first connecting plate is welded to the side wall of the first sliding rod. A second sliding groove is formed on the opposite side wall of the zipper to the first sliding groove, and a second sliding rod is slidably connected to the side wall of the first sliding groove. Two push blocks are integrally formed on the side wall of the second sliding rod, and a second connecting plate is welded to the side wall of the second sliding rod. One end of the fixed spring is welded to the first sliding rod, and the other end of the fixed spring is welded to the second connecting plate. The first sliding block, the second sliding block, and two sets of interlocking chain teeth engage with each other. A sliding unit that cooperates with the push block is provided at the top of the first sliding rod.

[0009] Furthermore, the sliding unit includes a sliding block, a pushing groove, a limiting groove, a limiting spring, a limiting block, and a pull tab. The top of the top pull head has a pushing groove, and a sliding block is slidably connected inside the pushing groove. A through hole is opened on the side wall of the sliding block, and a pull tab is installed in the through hole. A limiting block is integrally formed at the bottom of the sliding block, and a limiting groove is opened at the bottom of the pushing groove. One end of a limiting spring is welded to each side of the limiting block, and the other ends of the two limiting springs are welded to the two side walls opposite to the limiting groove. The sliding block and the pushing block cooperate with each other.

[0010] Furthermore, the first sliding groove and the second sliding groove have a plurality of support grooves on their sidewalls, and the first sliding rod and the second sliding rod have support rods integrally formed on their sidewalls that cooperate with each support groove.

[0011] In summary, the beneficial effects of this utility model are as follows: This invention increases the smoothness of the zipper by adding a smoothing component, which reduces the friction between the zipper teeth and the connecting block. Continuous smoothness can be maintained by replacing the internal lubrication rollers. A secure component allows the zipper pull to be suspended and locked, preventing the zipper from moving when it is halfway open or closed, making it suitable for more scenarios. The zipper teeth under the zipper pull fit tightly together, ensuring a secure connection. This invention reduces the friction between the zipper teeth and the connecting block while simultaneously tightening and fixing the zipper teeth. The tightening achieves suspension locking, and the zipper can be stopped and locked at any time during opening and closing. Attached Figure Description

Detailed Implementation

[0013] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described in detail below: This utility model discloses a smooth zipper with a strong connection, such as... Figure 1 , Figure 2As shown, a smooth zipper with a secure connection includes a zipper fabric 1. Two zipper fabrics 1 have zipper teeth 2 on their inner sides, which interlock. A top pull head 3 is slidably connected to the top of each zipper tooth 2, and a bottom pull head 5 is slidably connected to the bottom of each zipper tooth 2. A connecting block 6 is welded to the bottom of the top pull head 3, and the connecting block 6 is welded to the bottom pull head 5. A smoothing component is provided inside the connecting block 6, and a securing component is provided inside the top pull head 3. In this embodiment, by adding a smoothing component, the friction between the zipper teeth 2 and the connecting block 6 is reduced, thereby increasing the smoothness of the zipper. Continuous smoothness can be maintained by replacing the internal lubrication roller 16. By adding a securing component, the pull head can be locked in place, allowing the zipper to lock when it is halfway open, making it more suitable for more scenarios. Furthermore, the zipper teeth 2 under the pull head are tightly fitted together, resulting in a secure connection between the zipper teeth 2.

[0014] like Figure 2 , Figure 3 , Figure 5 As shown, the smoothing component includes a lubricating roller 16, a lifting block 8, a cover plate 17, and roller grooves 18. Two roller grooves 18 are formed on the side wall of the connecting block 6. One end of the lubricating roller 16 is mounted on the side wall of the two roller grooves 18 via a rotating shaft. The other end of the lubricating roller 16 is connected to the lifting block 8 via a rotating shaft. The top of the top pull head 3 is rotatably connected to the cover plate 17. In this embodiment, by adding the lifting block 8, the lubricating roller 16 can be easily disassembled in the roller groove 18 after wear, thereby making the rotation of the lubricating roller 16 more continuous and smooth. Preferably, the lubricating roller 16 is made of hard wax material to provide lubrication.

[0015] like Figure 1 , Figure 2 , Figure 3 As shown, the side wall of the cover plate 17 is provided with a locking protrusion 19, and the side wall of the connecting block 6 is provided with a locking groove 7 that cooperates with the locking protrusion 19. When the locking protrusion 19 and the side wall of the top pull head 3 are in contact with each other, the locking protrusion 19 and the locking groove 7 are locked together. In this embodiment, by adding the locking protrusion 19, the cover plate 17 can be rotated to open and close to facilitate the disassembly of the lubrication roller 16, and is fixed by the locking groove 7 and the locking protrusion 19.

[0016] like Figure 1 , Figure 4 , Figure 5As shown, the robust assembly includes a first sliding rod 10, a second sliding rod 11, a fixed spring 12, a first connecting plate 13, a second connecting plate 14, a push block 15, a first sliding groove 25, a second sliding groove 26, and a sliding unit. The outer wall of the top pull head 3 has a first sliding groove 25, and the first sliding rod 10 is slidably connected to the side wall of the first sliding groove 25. Two push blocks 15 are integrally formed on the side wall of the first sliding rod 10. A first connecting plate 13 is welded to the side wall of the first sliding rod 10. The zipper has a first sliding groove 25, and the opposite side wall has a second sliding groove 26. The second sliding rod 11 is slidably connected to the side wall of the first sliding groove 25. Two push blocks 15 are integrally formed on the side wall of the second sliding rod 11. A second connecting plate 14 is welded to the side wall of 11. One end of the first sliding rod 10 is welded to a fixed spring 12, and the other end of the fixed spring 12 is welded to the second connecting plate 14. The first sliding block 9, the second sliding block 9 and the two sets of interlocking chain teeth 2 are engaged with each other. The top of the first sliding rod 10 is provided with a sliding unit that cooperates with the push block 15. In this embodiment, by adding a fixed spring 12, the first sliding rod 10 and the second sliding rod 11 are clamped inward, thereby making the first sliding rod 10 and the second sliding rod 11 lock the chain teeth 2, and thus making the gap between the two sets of interlocking chain teeth 2 locked by the first sliding rod 10 and the second sliding rod 11. When the pull head stops sliding, the position of the pull head can be locked.

[0017] like Figure 1 , Figure 3 , Figure 4 As shown, the sliding unit includes a sliding block 9, a pushing groove 27, a limiting groove 20, a limiting spring 21, a limiting block 22, and a pull tab 4. The top of the top pull head 3 has a pushing groove 27, and the sliding block 9 is slidably connected inside the pushing groove 27. The side wall of the sliding block 9 has a through hole, and the pull tab 4 is installed in the through hole. The bottom of the sliding block 9 has a limiting block 22 integrally formed. The bottom of the pushing groove 27 has a limiting groove 20. One end of the limiting spring 21 is welded to both sides of the limiting block 22. The other end of the two limiting springs 21 is welded to the two side walls opposite to the limiting groove 20. The sliding block 9 and the pushing block 15 cooperate with each other. In this embodiment, by adding the sliding block 9, the sliding block 9 can be moved up and down, thereby causing the sliding block 9 to squeeze the pushing block 15 to move. Under the action of the sliding block 9, the fixing spring 12 is pressed, thereby causing the first sliding rod 10 and the second sliding rod 11 to move to both sides, and causing the gap between the first sliding rod 10 and the second sliding rod 11 and the chain tooth 2 to separate and unlock.

[0018] like Figure 4 , Figure 5As shown, the first sliding groove 25 and the second sliding groove 26 have a plurality of support grooves 24 on their sidewalls, and the first sliding rod 10 and the second sliding rod 11 have support rods 23 integrally formed on their sidewalls that cooperate with each support groove 24. In this embodiment, by adding support rods 23, the first sliding rod 10 and the second sliding rod 11 are made more compatible with each other. The implementation principle of this utility model embodiment is as follows: When in use, first rotate the cover plate 17 on the top pull head 3 to separate the engaging protrusion 19 from the engaging groove 7. Then, pinch the lifting block 8 to install the lubricating roller 16 into the roller groove 18, and rotate the cover plate 17 so that the engaging protrusion 19 enters the engaging groove 7 to complete the engaging and locking. Next, pull the handle 4 downwards or upwards to make the sliding block 9 slide in the push groove 27, thereby making the sliding block 9 squeeze and push the push block 15 to drive the first sliding rod 10 and the second sliding rod 11 to move, so that the first sliding rod 10 and the second sliding rod 11 are separated from the gap between the adjacent chain teeth 2, and then the chain teeth 2 are made to fit with the lubricating roller 16 to complete the smooth up and down movement; Finally, the limiting spring 21 resets the transmission limiting block 22, causing the sliding block 9 to move to the middle position. This allows the first sliding rod 10 and the second sliding rod 11 to be locked together with the gaps between the two sets of meshing chain teeth 2 under the action of the fixed spring 12, so that the zipper can be stopped and locked at any time during the opening and closing process.
