Technical Field
[0001] This utility model relates to the field of baby carrier technology, and in particular to an adjustable baby carrier. Background Technology
[0002] In modern parenting, taking infants out is a frequent scenario for parents. Baby carriers, as a convenient tool for carrying babies, are increasingly favored by parents. However, traditional baby carriers have many shortcomings in design and function. With the improvement of people's living standards and the pursuit of convenience in childcare, the requirements for baby carriers are also increasing. Parents not only want baby carriers to safely and comfortably carry their babies, but also expect them to be easily adjustable in different usage scenarios to adapt to the baby's constantly changing state and needs. Therefore, developing a more practical and adaptable baby carrier is particularly important.
[0003] Most existing baby carriers employ relatively simple and traditional designs in terms of mechanical structure and technical principles. They typically connect various parts using ordinary straps and buckles, and the methods for adjusting tightness are also relatively simple. For example, some carriers rely solely on a few eyelets sewn onto the straps, with the tightness adjusted by threading the strap through different eyelets. This method is cumbersome and has limited precision. Other carriers, while having adjustment functions, have adjustment parts distributed in different locations on the carrier, requiring both hands to operate multiple parts simultaneously. This is very inconvenient for parents carrying a baby alone, as they need to adjust the carrier while holding the infant.
[0004] However, existing baby carriers have a significant problem: they cannot be easily adjusted to suit the baby's position. In practice, parents often need to quickly adjust the carrier in different environments. For example, when walking outdoors, a baby may cry due to discomfort, requiring a rapid adjustment of the carrier's tightness and position. Existing adjustment methods often require considerable time and effort, failing to meet this immediate need. Furthermore, due to the lack of convenience, it's difficult to precisely adjust the carrier according to the baby's size, posture, and the parent's specific needs. This not only affects the carrier's suitability for various baby positions but also significantly reduces its adjustability, causing considerable inconvenience for parents. Therefore, this paper proposes an adjustable baby carrier to address these issues. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 and Figure 2 This utility model provides one embodiment: an adjustable baby carrier, including a carrier body 1. The carrier body 1 is made of a soft and breathable high-quality cotton-linen blend material, which ensures the comfort of the baby's skin and has good breathability to prevent the baby from feeling stuffy and uncomfortable. A first carrier strap 4 and a second carrier strap 17 are fixedly connected to the outer wall of the carrier body 1. The first carrier strap 4 and the second carrier strap 17 are placed crosswise. Both are made of high-strength nylon fiber material, which is not only sturdy and durable, but also has a certain degree of elasticity to adapt to different uses. In this application scenario, one side of the carrier strap 4 is equipped with an adjustment buckle 5. The adjustment buckle 5 is made of engineering plastic, which has good toughness and strength. Its surface is also designed with anti-slip texture for easy operation by parents. The other side of the adjustment buckle 5 is fixedly connected to a connecting buckle 6. The connecting buckle 6 is made of engineering plastic, which is sturdy and corrosion-resistant. Its outer wall is tightly attached to the outer wall of the carrier body 1 to ensure the stability of the connection. The outer wall of the connecting buckle 6 is set on the outer wall of the carrier body 1. The carrier body 1 has an adjustment component inside, a fixing component on the outer wall of the carrier strap 4, and a protective component on the outer wall of the carrier body 1.
[0034] The adjustment component includes an elastic band 9, which is made of highly elastic rubber and covered with a soft cotton fabric to ensure elasticity without irritating the baby's skin. The elastic band 9 is located inside the main body 1 of the baby carrier. A waist belt 7 is located on the outer wall of the main body 1 of the baby carrier. An adjustment shell 8 is located on the outer wall of the elastic band 9. A button 10 is slidably connected inside the adjustment shell 8. The button 10 is ergonomically designed with a smooth surface and a certain curvature for easy finger pressing. An adjustment groove 11 is opened inside the button 10, and the outer wall of the elastic band 9 is slidably connected to the adjustment groove 11. A connecting post 12 is fixedly connected to the bottom of the button 10, and a limiting device is fixedly connected to the bottom of the connecting post 12. The disc 13 is slidably connected to the outer wall of the limiting disc 13 inside the adjusting housing 8. A spring 14 is installed inside the adjusting housing 8. The top of the spring 14 is fixedly connected to the bottom of the limiting disc 13, and the bottom of the spring 14 is fixedly connected to the inner wall of the adjusting housing 8. The protective components include a hood 2, made of soft pure cotton fabric with a delicate touch that will not harm the baby's delicate skin. The hood 2 is set on the outer wall of the carrier body 1. A hook 3 is fixedly connected to the outer wall of the carrier body 1. The hook 3 is made of stainless steel, making it sturdy and durable. Both ends of the hood 2 can be easily hung on the outer wall of the hook 3, providing thoughtful protection for the baby's head.
[0035] Specifically, when taking a baby out, the first step is to place the main body 1 of the baby carrier flat in front of your chest, ensuring it is positioned correctly and comfortably, laying a good foundation for subsequent operations. Next, carefully cross the first and second straps 17, and then secure them firmly to your chest using the connecting buckle 6, forming a stable frame. After completing these steps, carefully place the baby in the appropriate position on the carrier. When the baby is facing the carrier, to provide comprehensive protection for the baby's head, the hood 2 can be accurately hung on the top of the hook 3. When the baby needs to be carried in a seated position, the operation is also simple; just gently press the button 10. The button 10 then moves the carefully designed internal adjustment groove 11, which in turn moves the connecting post 12 synchronously. The connecting post 12 then moves the limiting disc 13, compressing the spring 14. At this point, the elastic band 9 can be moved flexibly to adjust the internal tightness. After adjustment, release button 10, spring 14 will rebound, causing adjustment groove 11 to move upward, thus firmly fixing elastic band 9 to adapt to different travel conditions and infant needs.
[0036] Reference Figure 1 , Figure 3 and Figure 4The fixing components include connector 15, which plays a crucial connecting and supporting role in the entire carrying strap system. It is made of high-strength polycarbonate plastic, a material with excellent strength and toughness, capable of withstanding tensile forces while also possessing good wear resistance, ensuring long-term durability. Connector 15 is fixedly connected to the outer wall of carrying strap 4 at its top, and a fixing post 18 is fixedly connected to its bottom. The fixing post 18 has a slot 19 inside, and connector 26 is provided on the outer wall of the fixing post 18. Connector 26 is fixedly connected to the outer wall of carrying strap 27 at its bottom, and a moving groove 24 is formed inside connector 26. The inner wall of the moving groove 24 is very smooth and has undergone fine polishing to ensure internal stability. The components can slide smoothly. Connector 26 has a sliding column 21 inside, and a retaining ball 20 is fixedly connected to one end of the sliding column 21. The retaining ball 20 is a round metal ball made of high-strength brass with a polished surface to reduce friction. The outer wall of the retaining ball 20 can slide smoothly inside the retaining groove 19. It achieves an important fixing function by cooperating with the retaining groove 19. The outer wall of the retaining ball 20 is slidably connected to the inside of the retaining groove 19. The other end of the sliding column 21 is fixedly connected to a limiting ring 22. The outer wall of the limiting ring 22 is slidably connected to the inside of the moving groove 24. Connector 26 has a spring 23 inside. One end of the spring 23 is fixedly connected to the inner wall of the moving groove 24, and the other end of the spring 23 is fixedly connected to the inner wall of the limiting ring 22.
[0037] Specifically, a clever fixing mechanism exists during the crossing of the first and second baby carrier straps 17. When they cross, the fixing post 18 slowly slides into the connector 16. Because the contact surface of the retaining ball 20 is designed as a curved surface, this special structure allows it to move smoothly when pushed by the fixing post 18. Immediately afterwards, the retaining ball 20 drives the sliding post 21 to move as well. The sliding post 21 then drives the limiting ring 22 to slide smoothly within the moving groove 24, during which the second spring 23 is compressed. When it reaches a specific fixed position, the second spring 23 quickly rebounds, causing the retaining ball 20 to slide precisely into the retaining groove 19, thus achieving a secure fixation and keeping the connection of the baby carrier stable, ensuring the baby carrier is safe and reliable during use.
[0038] Working principle: When taking the baby out, the main body 1 of the carrier can be placed in front of the chest, and then the first carrier strap 4 and the second carrier strap 17 can be crossed and fixed in front of the chest through the connecting buckle 6. Then place the baby in the carrier. When the baby is facing the carrier, the hood 2 can be hung on the top of the hook 3 to protect the baby's head. When the baby is sitting on the back, the button 10 can be pressed. The button 10 will move the internal adjustment groove 11 and the connecting column 12. Then the connecting column 12 will move the limiting disc 13, compressing the spring 14, thereby moving the elastic band 9 to adjust the internal tension. Finally, by pressing the button 10, the spring 14 will rebound and move the adjustment groove 11 upward to fix the elastic band 9, adapting to different situations.
[0039] In addition, when the first shoulder strap 4 and the second shoulder strap 17 cross, the fixing post 18 is driven to slide into the second connector 16. Because the contact surface of the retaining ball 20 is arc-shaped, it is pushed to move. Then, the retaining ball 20 drives the sliding post 21 to move. Then, the sliding post 21 drives the limiting ring 22 to slide inside the moving groove 24, compressing the second spring 23. When it reaches the fixed position, the spring 23 rebounds and drives the retaining ball 20 to slide into the retaining groove 19 for fixation, keeping the connection stable.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
