[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Reference Figure 2 - Figure 4 The utility model provides an embodiment: a packaging bag with a safety buckle, including a packaging bag body 1, a zipper 2 is arranged inside the packaging bag body 1, a slider 3 is slidably connected to the outer wall of the zipper 2, a limiting plate 5 is fixedly connected inside the packaging bag body 1, a shell 4 is slidably connected to one side of the outer wall of the limiting plate 5, the shell 4 is fixedly connected to the outer wall of the slider 3, a plurality of limiting holes 6 are opened inside the limiting plate 5, a sliding button 7 is slidably connected to the top of the shell 4, a wedge block 8 is fixedly connected to the bottom of the sliding button 7, a sliding column 9 is slidably connected to the wedge block 8, and a spring is fixedly connected to one side of the outer wall of the wedge block 8. A spring 10, one end of which is fixedly connected to the inside of the housing 4, a transmission column 11 is slidably connected to the inside of the wedge block 8, a limit block 12 is fixedly connected to the bottom of the transmission column 11, a slide column 14 is slidably connected to the inside of the limit block 12, a spring 13 is fixedly connected to one side of the outer wall of the limit block 12, one end of the spring 13 is fixedly connected to one side of the outer wall of another limit block 12, a plurality of fixed blocks 15 are fixedly connected to one side of the outer wall of the packaging bag body 1, a handle 16 is slidably connected to the inside of the fixed block 15, and a protective component is arranged inside the fixed block 15, and the protective component is used to prevent the internal components from being accidentally touched;
[0026] Specifically, when using a packaging bag with a safety buckle and needing to close the packaging bag body 1, first pinch the outer shell 4 and slide the slide button 7 to the lower left. The movement of the slide button 7 will drive the wedge block 8 to move to the lower left. The movement of the wedge block 8 is the key action of the safety buckle mechanism. By changing its position, the transmission column 11 is subjected to force, thereby driving the limit block 12 to disengage from the inside of the limit plate 5. The separation of the limit block 12 from the inside of the limit plate 5 is a prerequisite for realizing the sliding of the outer shell 4. Once the limit block 12 is disengaged, the outer shell 4 can easily slide to one end of the zipper 2. In the process of sliding the outer shell 4, the slider 3 will move accordingly, thereby bringing The zipper 2 is driven to close, and then the slide button 7 can be released. At this time, the internal spring 10 will automatically pull the wedge block 8 to reset, and the spring 2 13 will push the two limit blocks 12 into the limit hole 6 to limit the shell 4. After the limit blocks 12 enter the limit hole 6, the shell 4 will be firmly locked in place, ensuring that the packaging bag body 1 is safely closed to prevent accidental opening during transportation or storage, and also to prevent children from opening it by mistake. For packaging bags containing dangerous goods, such as medicines, chemicals or sharp small objects, the safety buckle can prevent children from opening it out of curiosity, thereby reducing the risk of accidents to children.
[0027] Reference Figure 3 - Figure 5 The protection assembly includes a protection plate 17 and a block 18, the top of the protection plate 17 is fixedly connected to the bottom of the block 18, and the outer wall of the protection plate 17 is slidably connected to the inside of the fixed block 15;
[0028] Specifically, in the packaging bag with a safety buckle, the protective plate 17 and the card block 18 are used to prevent the components inside the fixing block 15 from being touched due to external reasons during daily use. The protective plate 17 can protect its internal components.
[0029] Reference Figure 3 - Figure 5 The handle 16 is internally slidably connected to a limiting bead 25, and the outer wall of the limiting bead 25 is slidably connected to the inside of the fixed block 15. A groove 26 is provided inside the fixed block 15, and the outer wall of the limiting bead 25 is slidably connected to the inside of the groove 26. The fixed block 15 is internally rotatably connected to a rotating column 19, and the outer wall of the limiting bead 25 is slidably connected to a limiting column 23. A worm 20 is fixedly connected to the top of the rotating column 19, and a worm wheel 21 is rotatably connected to the fixed block 15. The worm wheel 21 is meshed with the worm 20. A hole groove 24 is provided inside the limiting column 23, and a tooth plate 22 is fixedly connected to one side of the outer wall of the limiting column 23, and the tooth plate 22 is meshed with the worm wheel 21;
[0030] Specifically, when the packaging bag with the safety buckle is used for a long time, the handle 16 will accumulate dirt or bacteria, so it needs to be cleaned regularly to maintain hygiene and extend its service life. When the handle 16 is disassembled, the protective plate 17 is first moved to the left. After the protective plate 17 is successfully removed, the next operation is to rotate the rotating column 19. The rotating column 19 is a key component of the worm 20. Its rotation will drive the worm 20 to rotate accordingly. The rotation of the worm 20 is one of the key steps to realize the disassembly of the handle 16. It converts the rotational motion into the linear motion through mechanical linkage. The rotation of the worm 20 causes the worm wheel 21 to rotate under force. When the worm wheel 21 rotates, it will drive the tooth plate 22 to descend. The tooth plate The descent of 22 is an important step in realizing the disassembly of the handle 16. It transmits force to the limiting column 23 through mechanical linkage, so that the limiting column 23 also descends. When the limiting column 23 descends, it will drive the hole groove 24 to move one side of the limiting bead 25 to release the limitation of the limiting bead 25. The limiting bead 25 is a key component for fixing the handle 16. After the limiting bead 25 is released, the handle 16 can be taken out for necessary cleaning and disinfection. Because after long-term use, the handle 16 is easily contaminated with stains and bacteria. Being able to take it off for cleaning can effectively remove dirt and germs, providing a cleaner and healthier use environment, especially when it is used to carry food or items that are in direct contact with the body. This is particularly important.
[0031] Working principle: When using the packaging bag with a safety buckle, when the packaging bag body 1 needs to be closed, first pinch the shell 4, and then slide the slide button 7 to the lower left. At this time, the slide button 7 will drive the wedge block 8 to move to the lower left. The movement of the wedge block 8 causes the transmission column 11 to be forced to drive the limit block 12 to separate from the inside of the limit plate 5. At this time, the shell 4 can be slid to one end of the zipper 2. During this sliding process, the slider 3 will be driven to close the zipper 2. After the zipper 2 is closed, release the slide button 7. At this time, the spring 10 pulls the wedge block 8 to reset, and the spring 2 13 will push the two limit blocks 12 in. The packaging bag body 1 will be safely closed when the handle 16 is cleaned after long-term use by inserting the limiting hole 6. Then the handle 16 is cleaned when the handle 16 is cleaned. The protective plate 17 is first moved to the left, and then the rotating column 19 is rotated. When the rotating column 19 rotates, the worm 20 is driven to rotate, which causes the worm wheel 21 to rotate under force. When the worm wheel 21 rotates, the tooth plate 22 is driven to descend, and the limiting column 23 is driven to descend at the same time, until the hole groove 24 is displaced to one side of the limiting bead 25 to release the limit of the limiting bead 25. At this time, the handle 16 can be taken out for cleaning.
[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
