Description

Technical Field

[0001] This utility model belongs to the technical field of bags and leather goods, specifically relating to a stitchless zipper that is easy to install. Background Technology

[0002] In recent years, with the rapid development of the luggage and leather goods industry, zippers, as common connecting components in luggage and leather goods, directly affect the convenience and durability of these products. Currently, most mainstream luggage and leather goods zippers on the market are fixed with stitching, where the zipper is sewn onto the luggage and leather fabric using a sewing machine. This method has been widely used in traditional manufacturing.

[0003] Currently, the most common method for securing zippers is by stitching. However, when the threads become loose, it's difficult to quickly reattach the zipper to clothing without using a sewing machine or similar equipment. This can also lead to the zipper coming off and affecting the normal use of bags and leather goods. Furthermore, after repeated disassembly or cleaning, the stitching on stitched zippers is prone to wear and breakage, shortening the zipper's lifespan and increasing maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a zipper strip that is easy to install and requires no stitching, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A stitch-free zipper strip that is easy to install includes an installation component, comprising a bag edge and a zipper body positioned opposite each other on the surface of a bag. Both sides of the zipper body are fixedly connected to nylon threads for quick-connection and installation with the bag edge. The nylon threads are slidably connected to the bag edge.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0016] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a zipper strip that is easy to install without stitching. It includes an installation component, including a bag edge 10 and a zipper body 11 located opposite each other on the surface of the bag. Both sides of the zipper body 11 are fixedly connected with nylon threads 12 that can be quickly connected to the bag edge 10. The nylon threads 12 are slidably connected to the bag edge 10. An outer support component 13 is provided on the inner side of the nylon thread 12. A guide component 14 is provided between the outer support component 13 and the nylon thread 12.

[0017] During the sliding installation of the zipper body 11 and the bag edge 10, the guide component 14 can help the nylon threads 12 on both sides of the zipper body 11 to quickly connect with the guide rail of the bag edge 10. Then, as the nylon threads 12 slide inside the guide rail, they can cooperate with the external support component 13 to fasten the nylon threads 12 inside the guide rail of the bag edge 10, thereby quickly realizing the installation of the zipper body 11.

[0018] Furthermore, the external support assembly 13 includes a pull rod 131 slidably connected to the inner side of the nylon line 12. Several cone blocks 132 are fixedly connected to the surface of the pull rod 131, and several cylinders 133 are fixedly connected to the inner side of the nylon line 12. The pull rod 131 is slidably connected to the cylinders 133, and rubber blocks 135 are fixedly connected to the upper ends of each cylinder 133. The guide assembly 14 includes a guide block 141 fixedly connected to the upper end of the pull rod 131. A circular groove 142 is formed on the inner side of the guide block 141, and a pull plate 143 is fixedly connected to the inner wall of the circular groove 142.

[0019] When the nylon thread 12 moves upward to a higher position inside the guide rail of the bag edge 10, the lower side of the bag edge 10 will abut against the pull rod 131, which can push the pull rod 131 to pull multiple cone blocks 132 to move synchronously, and then enter the inner wall of the rubber block 135, causing the rubber block 135 to expand and support the nylon thread 12. This allows the nylon thread 12 to expand at multiple points inside the guide rail, thereby increasing the stability of the zipper body 11 installed on the bag edge 10 through the nylon thread 12.

[0020] Preferably, the lower diameter of the cone block 132 is smaller than the diameter of the hole in the rubber block 135, and the diameter of the hole in the rubber block 135 is larger than the diameter of the pull rod 131. The lower diameter of the guide block 141 is smaller than the opening size of the mating groove of the bag edge 10, and the cross-section of the guide block 141 is trapezoidal.

[0021] It should be noted that when the pull rod 131 moves down, the lower end of the cone block 132, being smaller than the hole size of the rubber block 135, can quickly insert into the inner wall of the rubber block 135 and compress the rubber block 135 to achieve expansion. The lower end of the guide block 141 is smaller than the docking groove size of the bag edge 10, which facilitates the entry of the nylon thread 12 into the inner side of the docking groove. Furthermore, due to its trapezoidal cross-section, its inclined surface can further enhance the guiding effect.

[0022] In use, the user can first align the nylon threads 12 on both sides of the zipper body 11 with the pre-set docking grooves on the bag edge 10. Using the trapezoidal structure of the guide block 141, the nylon threads 12 are guided to slide into the grooves. The user can then lift the nylon threads 12, allowing them to be installed gradually along the guide rail of the bag edge 10. When the nylon threads 12 drive the lower pull rod 131 to abut against the lower edge of the bag edge 10, the further upward movement of the nylon threads 12 will cause the bag edge 10 to block the movement of the pull rod 131. At this time, the nylon threads 12 move upward alone, while the pull rod 131 is limited, which will pull the surface cone block 132 to move towards the rubber block 135. The lower guide allows it to enter the rubber block. The inner wall of 135 is squeezed and the rubber block 135 is expanded outward. The expansion of the rubber block 135 will simultaneously drive the connection position of the rubber block 135 inside the nylon thread 12 to expand outward. Through multi-point expansion, the stability of the nylon thread 12 installed on the inner wall of the guide rail of the bag edge 10 can be increased. When the zipper body 11 needs to be cleaned or replaced, the user can pull the guide block 141 to move upward separately from the gap between the pull plate 143 and the circular groove 142, thereby causing the cone block 132 to be released from the squeezing of the inner side of the rubber block 135. Then, by pulling down, the nylon thread 12 can be released from the inner wall of the guide rail of the bag edge 10, thereby completing the disassembly of the zipper body 11 and making it convenient for reinstallation and use. Example 2

[0023] Reference Figures 1-4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a limiting component, including a ring 20 fixedly connected to the upper end of the nylon thread 12. Three push blocks 21 are slidably connected to the surface of the ring 20. A limiting plate 22 is fixedly connected to the surface of the push blocks 21. A power component 23 is provided between each of the three push blocks 21 and the guide component 14. The power component 23 includes a round block 231 fixedly connected to the lower end of the guide block 141. Three push plates 232 are rotatably connected to the surface of the round block 231. All three push plates 232 are rotatably connected to the surface of the push block 21.

[0024] Specifically, when the pull rod 131 moves multiple cone blocks 132 downward, it pulls the round block 231 downward. At the same time, the round block 231 pushes the push plate 232 downward, which can drive the three push blocks 21 to slide outward and open. The limiting plate 22 can limit the nylon thread 12 from the top, so that after the nylon thread 12 is installed with the bag edge 10, it cannot be disconnected without external force.

[0025] Preferably, the size of the circular block 231 is adapted to the inner wall size of the nylon thread 12, and the circular block 231 and the nylon thread 12 are in a coaxial position.

[0026] It should be noted that when the circular block 231 moves down, the arc surface of the circular block 231 fits against the inner wall of the nylon thread 12, which can further increase the friction and ensure that after the circular block 231 drives the push plate 232 to rotate, it will not automatically reset, which facilitates the limiting operation of the limiting plate 22 on the nylon thread 12.

[0027] In use, when the pull rod 131 moves upward relative to the nylon thread 12 under the obstruction of the bag edge 10, the circular block 231 at its upper end will move downward simultaneously. At this time, the three push plates 232 rotatably connected to the surface of the circular block 231 will push the push block 21 to slide outward along the surface of the ring 20 due to the displacement of the circular block 231. During the sliding process, the push block 21 drives the limiting plate 22 to unfold simultaneously. The three limiting plates 22 form a limiting structure on the upper end of the nylon thread 12, which laterally limits the docking position between the nylon thread 12 and the bag edge 10 from the upper end, preventing the nylon thread 12 from being used. When the zipper moves up and down due to external pulling, the matching design between the round block 231 and the inner wall of the nylon thread 12 can enhance the friction between the two, ensuring the positional stability of the push plate 232 after pushing the push block 21, so that the limiting plate 22 can remain in the limiting state. When disassembly is required, simply pull up the pull plate 143 to move the guide block 141 upward, and the round block 231 will move upward. Then the push plate 232 will pull the push block 21 to reset, and the limiting plate 22 will retract to release the limiting. The nylon thread 12 can then be pulled out from the docking groove of the bag edge 10, realizing the quick disassembly and replacement of the zipper body 11.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
