Description

Technical Field

[0001] This utility model relates to the field of baby hip stool technology, specifically a baby hip stool with adjustable shoulder straps. Background Technology

[0002] Baby hip seats, as an auxiliary childcare tool, distribute the pressure of the baby's weight onto the adult's shoulders and arms by supporting the baby on the adult's waist. They are widely used in daily carrying scenarios for babies aged 0-36 months. Their core function is to balance safety (preventing the baby from slipping) and comfort (even weight distribution on the adult's waist and natural sitting posture for the baby). With the increasing demand for refined childcare, the adjustable shoulder straps of hip seats have become crucial. Inappropriate shoulder strap length or tightness can lead to shoulder marks on the adult, uneven weight distribution on the waist, and even cause the baby to tilt their sitting posture (increasing the risk of hip dysplasia). Therefore, the flexibility and stability of the shoulder strap adjustment directly determine the practical value of the product and are the core indicators that distinguish high-end hip seats from ordinary products.

[0003] To address the aforementioned deficiencies, existing technology (Chinese Patent No. CN211408350U, published on 2020-09-04) provides a waist stool that, by fixing a housing to the shoulder strap, rotatably connecting both ends of a roller to the housing with a coil spring at one end, fixing both ends of the coil spring to the housing and the roller respectively, and fixing both ends of an adjustment belt to the roller and the guard respectively, achieves the function that, under the action of external force, the adjustment belt can drive the roller to rotate inside the housing against the elastic force of the coil spring, and when the external force is removed, the roller drives the adjustment belt to rotate in the opposite direction under the action of the coil spring, making the extension and retraction of the adjustment belt convenient and automatically retractable.

[0004] The above solution requires adjusting the shoulder straps on both sides individually when using it, which is tedious and time-consuming. The adjustment process can also put a lot of pressure on one shoulder. In addition, when the baby sits on the hip seat for a long time, the user's shoulders and the baby's buttocks are prone to feeling hot and sweaty, which can cause discomfort. Utility Model Content

[0005] The purpose of this utility model is to provide a baby hip seat with adjustable shoulder straps to solve the problems mentioned in the background art. In the process of using the existing baby hip seat with adjustable shoulder straps, it is tedious and time-consuming to adjust the shoulder straps on both sides one by one. During the adjustment process, it will also put great pressure on one shoulder. At the same time, when the baby sits on the hip seat for a long time, the user's shoulders and the baby's buttocks are prone to stuffiness and sweating, which will cause discomfort.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a shoulder strap adjustable baby waist stool, comprising a waist stool body, an adjustable waist belt fixed to the outside of the waist stool body, a supporting shoulder strap body between the waist stool body and the top of the adjustable waist belt, a connecting strap for adjusting components between the shoulder strap body and the adjustable waist belt, and a protective strap connected to the left side of the waist stool body and the shoulder strap body.

[0007] The top side of the shoulder strap body has a notch, and a cushioning and breathable component is provided in the notch. The cushioning and breathable component blows air to the user's shoulder through the first air jets that are equally spaced at the bottom of the shoulder strap body.

[0008] The hip stool body is equipped with a load-bearing and breathable component inside. The load-bearing and breathable component provides ventilation and prevents stuffiness on the baby's buttocks through a second air vent that is equally spaced on the top of the hip stool body.

[0009] Furthermore, the adjustment component on the connecting strap includes an adjustment rod rotatably connected to the right side of the connecting strap. The left side of the adjustment rod extends into the interior of the connecting strap. The middle part of the connecting strap is configured as a hollow structure. A pull cord is wound around the outside of the adjustment rod. The top of the pull cord is fixedly connected to the bottom right side of the shoulder strap body. The shoulder strap body is configured as a "Y" shaped structure. The right side of the shoulder strap body is slidably connected to the connecting strap.

[0010] Furthermore, a return spring is provided between the adjusting rod and the outer side of the connecting belt. The left end of the adjusting rod is located in the middle of the positioning cylinder. The positioning cylinder is fixed to the left inner wall of the connecting belt. A first positioning tooth is installed at an equal angle on the outer side of the adjusting rod. The first positioning tooth and the second positioning tooth abut against each other. The second positioning tooth is fixed at an equal angle to the inner wall of the positioning cylinder. The horizontal displacement distance of the adjusting rod is less than the distance the adjusting rod slides inside the positioning cylinder.

[0011] Furthermore, the cushioning and breathable component includes an arc-shaped cushioning pad installed in the recess, the cushioning pad being configured as a hollow structure, and cushioning springs being installed at equal intervals inside the cushioning pad.

[0012] Furthermore, the bottom of the cushioning pad is provided with air outlets at equal intervals, and the positions of the air outlets correspond one-to-one with the positions of the first air outlets, which are positioned directly facing the user's shoulder.

[0013] Furthermore, the bearing and ventilation component includes an inner cavity opened inside the waist stool body, the inner cavity is provided with a movable plate, and a connecting spring is installed between the top of the movable plate and the inner cavity, the swaying during walking will intermittently squeeze the movable plate.

[0014] Furthermore, an airbag is provided below the movable plate. The airbag is fixed to the bottom of the inner side of the inner cavity. The air outlet of the airbag is correspondingly arranged with the second air outlet, which is positioned directly opposite the baby's buttocks.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This adjustable baby hip seat allows for simultaneous adjustment of the shoulder strap length via an adjustment rod during use. The locking teeth ensure a proper fit. When worn by an adult, the shoulder cushioning pads are depressurized by a return spring, and the compression during movement generates airflow for heat dissipation through the first air vent. When the baby sits down, the movement and swaying cause the moving plate to compress the airbag, and the second air vent continuously ventilates the buttocks, significantly improving comfort and safety.

[0017] 1. Furthermore, the "Y"-shaped shoulder strap body can simultaneously adjust the length of the shoulder strap on both sides of the shoulder through the adjustment rod on the connecting strap. The length of the shoulder strap body is locked by the first positioning tooth and the second positioning tooth interlocking and abutting. This structure ensures that the shoulder strap body is tight on both sides after adjustment, avoids pressure on one side, and is easy to operate.

[0018] 2. Furthermore, the cushioning pad in the shoulder strap body can absorb the impact of the baby's weight through the equally spaced cushioning springs inside, reducing shoulder marks and soreness. When the adult moves, the compression between the shoulder and the cushioning pad causes the air inside the pad to be ejected from the first air outlet, directly blowing on the shoulder skin.

[0019] 3. Furthermore, the periodic swaying of an adult walking causes the moving board to move up and down repeatedly, intermittently compressing the airbag below. After the airbag is compressed, the internal air is ejected from the second air outlet at the top of the waist stool body directly towards the baby's buttocks through the air outlet, forming a continuous airflow, reducing the temperature and humidity of the buttocks, and improving the comfort of use.

The length of the shoulder straps on both sides can be adjusted synchronously through the adjustment rod 6, and the positioning teeth lock to ensure a proper fit. When worn by an adult, the shoulder cushioning pad 13 is depressurized by the cushioning spring 14, and the compression during movement generates airflow to dissipate heat through the first air outlet 15. When the baby sits down, the movement and swaying cause the moving plate 17 to compress the airbag 19, and the second air outlet 20 continuously ventilates the buttocks, solving the problems of cumbersome adjustment and stuffiness and discomfort of traditional waist stools.

[0030] Example 2:

[0031] Based on Embodiment 1, a convenient shoulder strap adjustment mechanism is also disclosed, which allows for quick adjustment of the shoulder strap length. Please refer to [link / reference]. Figure 2 - Figure 3 As shown, its specific structure is as follows: The adjustment component on the connecting belt 3 includes an adjustment rod 6 rotatably connected to the right side of the connecting belt 3. The left side of the adjustment rod 6 extends into the interior of the connecting belt 3. The middle part of the connecting belt 3 is set as a hollow structure. A pull rope 7 is wound around the outside of the adjustment rod 6. The top of the pull rope 7 is fixedly connected to the bottom right side of the shoulder strap body 4. The shoulder strap body 4 is set as a "Y" shaped structure. The right side of the shoulder strap body 4 is slidably connected to the connecting belt 3. A return spring 8 is set between the adjustment rod 6 and the outside of the connecting belt 3. The left end of the adjustment rod 6 is located in the middle of the positioning cylinder 9. The positioning cylinder 9 is fixed on the left inner wall of the connecting belt 3. The first positioning tooth 10 is installed at equal angles on the outside of the adjustment rod 6. The first positioning tooth 10 and the second positioning tooth 11 are interlocked and abut against each other. The second positioning tooth 11 is fixed at equal angles on the inner wall of the positioning cylinder 9. The horizontal displacement distance of the adjustment rod 6 is less than the sliding distance of the adjustment rod 6 inside the positioning cylinder 9.

[0032] During use, when adjusting the length of the shoulder strap body 4, press the adjusting rod 6 to compress the return spring 8, causing the first positioning tooth 10 on its left side to disengage from the second positioning tooth 11 on the inner wall of the positioning cylinder 9, thus unlocking it. At this time, rotate the adjusting rod 6, and the pull rope 7 wrapped around its outer side will be wound or released, causing the right side of the "Y"-shaped shoulder strap body 4 to slide within the connecting strap 3, achieving synchronous adjustment of the length of both sides of the shoulder strap body 4 without the need for separate adjustment on one side. Release the adjusting rod 6, and the return spring 8 will reset and push the adjusting rod 6 to the left, causing the first positioning tooth 10 and the second positioning tooth 11 to interlock and engage again, locking the length of the shoulder strap body 4. This structure ensures that the shoulder strap body 4 is evenly tight on both sides after adjustment, avoiding unilateral pressure and making operation convenient.

[0033] Example 3:

[0034] Based on Embodiment 2, a cushioning and ventilation mechanism for the adult shoulder area is also disclosed to improve wearing comfort. Please refer to [link / reference]. Figure 1 - Figure 2 and Figure 4 - Figure 5 As shown, its specific structure is as follows: The cushioning and breathable component includes an arc-shaped cushioning pad 13 installed in the recess 12. The cushioning pad 13 is set as a hollow structure. Cushioning springs 14 are installed at equal intervals inside the cushioning pad 13. Air outlets are provided at equal intervals at the bottom of the cushioning pad 13, and the positions of the air outlets correspond one-to-one with the positions of the first air outlets 15. The first air outlets 15 are set facing the user's shoulder.

[0035] During use, the arc-shaped cushioning pad 13 inside the top recess 12 of the shoulder strap body 4 conforms to the shoulder curve, and the cushioning springs 14 distributed at equal intervals inside can absorb the impact of the baby's weight, reducing shoulder marks and soreness. When the adult moves, the compression between the shoulder and the cushioning pad 13 causes the air inside the pad to be ejected from the first air outlet 15, directly blowing on the shoulder skin, accelerating sweat evaporation, and solving the problem of stuffiness from wearing for a long time.

[0036] Example 4:

[0037] Based on Example 3, a support and ventilation mechanism for the baby's buttocks is also disclosed to prevent stuffiness and discomfort. Please refer to [link / reference].
