Technical Field

[0001] This utility model relates to the field of baby hip stool technology, specifically an adjustable waist support baby hip stool. Background Technology

[0002] A baby hip seat is an assistive childcare tool that is strapped to an adult's waist. It is suitable for infants and toddlers who are 3 months old and can sit up independently. The hip seat distributes the baby's weight to the adult's waist and shoulders, relieving fatigue in the arms and shoulders. However, traditional baby hip seats require repeated adjustments to the waist belt length using adjustable buckles before use. When loosening the belt during use, the process is relatively complicated and slow.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent with announcement number CN218451517U, announcement date 2023-02-07) provides an adjustable baby hip seat, including a hip seat body, a base plate, a front guard strap, shoulder straps, and a waist belt; several first zippers are arranged parallel to each other on the base plate, and the hip seat body is fixedly connected to the base plate through the first zippers, and the height is adjusted by fixing it to the first zippers at different heights; the front guard strap has a slit, and an extension fabric and a second zipper are sewn into the slit; one end of the shoulder strap is fixedly connected to the front guard strap, and the other end is fixedly installed on the base plate; by setting several first zippers on the base plate, the hip seat body can be installed at different heights on the base plate according to the baby's height, thus realizing the height adjustment of the hip seat body; by pulling the second zipper on the front guard strap, the slit can be opened and closed, thereby realizing the width adjustment of the front guard strap, thus facilitating the adjustment of the position and size of the baby hip seat, thereby improving the comfort of the baby sitting and the comfort of the parents when fastening the baby hip seat.

[0004] The aforementioned mechanism adjusts the waist and shoulder strap positions of the waist stool by adjusting the buckles, thereby achieving size adjustment. However, adjusting the buckles takes a lot of time in actual use, resulting in low overall flexibility during use. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable waist support type baby hip seat to solve the problem mentioned in the background art that the waist belt length of traditional baby hip seats is usually adjusted by adjusting buckles, which requires repeated adjustments before wearing the hip seat, and the process is complicated and slow when it needs to be loosened during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable waist support type baby hip seat, including a hip seat body, with fixing straps installed on both sides of the hip seat body, an adjusting strap being internally engaged with the fixing straps, and shoulder straps installed at the top of the adjusting straps and the inner side of the hip seat body, with a front guard strap installed at the front end of the shoulder straps via a connecting strap; an adjusting mechanism for adjusting the position of the adjusting straps is installed on the sides of the fixing straps, and a supporting guard strap is installed at the top end of the front guard strap via a limiting mechanism.

[0007] Furthermore, the adjustment mechanism includes a mounting box, which is fixedly connected to the side of the fixing belt. An internal gear ring is rotatably connected inside the mounting box. A gear meshes with the inner side of the internal gear ring, and a rotating rod is installed inside the gear. A traction rope is wound around the outer side of the internal gear ring, and the traction rope is connected to the other side of the adjustment belt.

[0008] Furthermore, a torsion spring is wound around the outer side of the internal toothed ring near the fixing belt, and the internal toothed ring and the fixing belt form an elastic structure through the torsion spring.

[0009] Furthermore, the internal toothed ring is rotatably connected to the fixed belt, and the inner side of the internal toothed ring is rotatably connected to the outer side of the rotating rod.

[0010] Furthermore, a positioning box is installed on the side of the mounting box near the rotating rod, and the height of the internal cavity of the positioning box is greater than the thickness of the gear.

[0011] Furthermore, the limiting mechanism includes a positioning block, and the positioning block is fixedly connected to the left and right sides of the support belt. The left and right sides of the top of the front belt are each equipped with a limiting block that matches the positioning block. The surface of the positioning block is provided with a slot. The front end of the limiting block is fixedly connected to a card block that matches the slot. A limiting piece is installed on the outer side of the card block.

[0012] Furthermore, the surface of the support belt is provided with reinforcing strips, and the reinforcing strips are evenly distributed on the surface of the support belt.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By rotating the rotating rod, the rotating rod can synchronously drive the gear to rotate. The gear meshes with the internal gear ring, so that the internal gear ring can be driven to rotate synchronously. When the internal gear ring rotates, it drives the traction rope to wind up or unwind. The traction rope passes through the waist stool body and connects to the adjustment belt on the other side. The movement and adjustment of the adjustment belt inside the fixed belt is realized by using the winding and unwinding of the traction rope.

[0015] Furthermore, when the adjustment state needs to be reset, the gear and the internal gear ring are separated by pulling the rotating rod outward, thereby causing the internal gear ring to lose its lock. The internal gear ring is automatically reset by the elastic force of the torsion spring, thereby realizing the synchronous reset and adjustment between the traction rope and the adjustment belt. This facilitates quick adjustment as needed and increases the overall flexibility during use.

[0016] Furthermore, the movable range of the gear is the height of the positioning box. The height of the positioning box is matched with the gear, so that when the rotating rod is pulled outward, it will not move too far and cause the entire mechanism to fall off, thus increasing the overall stability when resetting and adjusting.

[0017] 2. By using a neck support belt, the infant's neck can be provided with auxiliary support, effectively preventing the head from shaking due to lack of neck support when the infant is in a sitting position, thus increasing the protection of the infant.

[0018] Furthermore, by aligning the positions of the positioning block and the limiting block, and then engaging the card block with the card slot, the position is fixed. At the same time, since the card block is equipped with a limiting piece, the position of the card block can be restricted and engaged, thereby fixing the position of the support belt. In addition, the limiting piece itself can be made of rubber, which has a certain degree of support and elasticity, allowing the limiting piece to pass through the card slot and increasing the stability of the engagement between the card block and the card slot.

[0027] 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.

[0028] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 The technical solution shown addresses the problem that traditional baby hip seats typically require adjustment using buckles to lengthen the waistband, necessitating repeated adjustments before use and resulting in a complex and slow process when loosening the waistband during use. This adjustable waist support baby hip seat discloses an adjustment mechanism, including a hip seat body 3. Each side of the hip seat body 3 is equipped with a fixing strap 1, and an adjustment strap 2 is internally connected to the fixing strap 1. Shoulder straps 4 are installed at the top of the adjustment strap 2 and on the inner side of the hip seat body 3, with a front guard strap 6 connected to the front end of the shoulder strap 4 via a connecting strap 5. An adjustment mechanism for adjusting the position of the adjustment strap 2 is installed on the side of the fixing strap 1.

[0029] In this example, such as Figure 7 As shown, by wearing the baby waist stool, rotating the rotating rod 18 synchronously drives the gear 19 to rotate. The gear 19 meshes with the internal gear ring 15, causing the internal gear ring 15 to rotate synchronously. The internal gear ring 15, in turn, drives the traction rope 17 to wind up or unwind. The traction rope 17 passes through the waist stool body 3 and connects to the adjustment belt 2 on the other side. The winding and unwinding of the traction rope 17 allows the adjustment belt 2 to move and adjust within the fixed belt 1. When the traction rope 17 winds up, the adjustment belt 2 is pulled and moved towards the side of the waist stool body 3, thus reducing the size of the fixed belt 1 and the adjustment belt 2; conversely, it increases the size between the fixed belt 1 and the adjustment belt 2. Figure 6 and Figure 7As shown, when a reset adjustment is required, pulling the lever 18 outward separates the gear 19 from the internal gear ring 15, causing the internal gear ring 15 to lose its lock. The internal gear ring 15 then automatically resets due to the elastic force of the torsion spring 16, thereby achieving synchronous reset adjustment between the traction rope 17 and the adjusting belt 2. This facilitates quick adjustments as needed and increases the overall flexibility during use. Figure 7 As shown, the movable range of gear 19 is the height of positioning box 20. The height of positioning box 20 is adapted to gear 19, so that when rotating rod 18 is pulled outward, it will not move too far and cause the entire mechanism to fall off, increasing the stability of the whole when resetting and adjusting; the adjustment mechanism includes mounting box 14, which is fixedly connected to the side of fixing belt 1. An internal gear ring 15 is rotatably connected inside mounting box 14. Gear 19 is meshed on the inner side of internal gear ring 15, and rotating rod 18 is installed inside gear 19. A traction rope 17 is wound around the outer side of the toothed ring 15, and the traction rope 17 is connected to the other side of the adjusting belt 2; a torsion spring 16 is wound around the outer side of the inner toothed ring 15 near the fixing belt 1, and the inner toothed ring 15 and the fixing belt 1 are connected by the torsion spring 16 to form an elastic structure; the inner toothed ring 15 and the fixing belt 1 are rotatably connected, and the inner side of the inner toothed ring 15 is rotatably connected to the outer side of the rotating rod 18; a positioning box 20 is installed on the side of the mounting box 14 near the rotating rod 18, and the height of the internal cavity of the positioning box 20 is greater than the thickness of the gear 19.

[0030] Example 2: Figure 1 and Figure 2 The technical solution shown is designed to address the problem of insufficient neck support for infants during use: the adjustable lumbar support baby carrier discloses a support belt 7, with the top of the front support belt 6 fitted with the support belt 7 via a limiting mechanism.

[0031] In this example, because infants are young and have weak neck support stability, the neck support belt 7 can provide auxiliary support for their necks, effectively preventing head wobbling due to lack of neck support when they are sitting, thus increasing their protection. Figure 2 As shown, a reinforcing strip 8 is provided at the rear end of the support belt 7. The reinforcing strip 8 can increase the strength of the support belt 7 in actual use and prevent the support belt 7 from bending during use.

[0032] Example 3: Figure 1 , Figure 2 and Figure 4The technical solution shown addresses the problem that the support belt 7 is not easily adjustable according to the infant's condition during use: the adjustable waist support baby seat discloses a limiting mechanism, which includes a positioning block 9, which is fixedly connected to the left and right sides of the support belt 7. Limiting blocks 10 matching the positioning block 9 are installed on the left and right sides of the top of the front belt 6, and the surface of the positioning block 9 is provided with a slot 11. The front end of the limiting block 10 is fixedly connected to a locking block 12 matching the slot 11, and a limiting piece 13 is installed on the outer side of the locking block 12. The surface of the support belt 7 is provided with reinforcing strips 8, and the reinforcing strips 8 are evenly distributed on the surface of the support belt 7.

[0033] In this example, such as Figure 4 As shown, by aligning the positions of the positioning block 9 and the limiting block 10, and then engaging the locking block 12 with the locking slot 11, the position is fixed. Simultaneously, since the locking block 12 is equipped with a limiting piece 13, the position of the locking block 12 is restricted, thus fixing the position of the supporting strap 7. The limiting piece 13 itself can be made of rubber, providing support and elasticity, allowing it to pass through the locking slot 11 and increasing the stability of the engagement between the locking block 12 and the locking slot 11, thereby making the engagement between the locking slot 11 and the locking block 12 more secure. Figure 4 As shown, there are three slots 11. The locking block 12 can engage with the appropriate slot 11 according to the baby's condition, so that the support belt 7 can adjust the support for the baby's neck according to different situations.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
