[0002] In today's rapidly developing society, with the popularization of information technology and the improvement of the family education environment, children's learning and lifestyles have undergone significant changes. While the widespread use of electronic products provides children with abundant learning resources and entertainment options, it also brings unprecedented health challenges. Prolonged screen time, incorrect posture, and insufficient outdoor activities have become important factors affecting children's vision, spinal health, and even their overall physical and mental development.

[0003] Traditional child car seats are often designed as scaled-down versions of adult seats, lacking professional consideration for children's physical development and behavioral habits. These seats typically lack adjustment functions for key parameters such as height and angle, or have a limited range of adjustment, making it difficult to meet the ever-changing physical needs of children as they grow. More importantly, they often neglect the importance of posture correction, failing to effectively guide children to maintain correct posture, thus exacerbating health problems such as myopia and scoliosis. Specifically, incorrect posture, such as looking down while reading or hunching over, can cause prolonged tension in the eye muscles, increasing the risk of myopia. At the same time, prolonged poor posture of the spine can easily lead to spinal-related diseases such as scoliosis and cervical spondylosis. Utility Model Content

[0030] Example 1:

[0031] Please see Figure 1 - Figure 9 As shown, a child posture guiding chair includes:

[0032] The base plate 1 has grooves 11 on both sides and several insertion holes 12 on the side of the base plate 1 near the grooves 11.

[0033] Table body 2, table body 2 includes table legs 21, table legs 21 are movably installed on the top of the base plate 1, and a secondary table leg 22 is movably installed inside the table legs 21. Both table legs 21 and secondary table legs 22 are hollow structures, and a tabletop 23 is movably installed on the top of the secondary table leg 22.

[0034] Seat 3 includes a leg 31, which is fixedly installed on one side of the base plate 1. A secondary leg 32 is movably installed inside the leg 31. Both the leg 31 and the secondary leg 32 are hollow structures. A seat 33 is movably installed at the top of the secondary leg 32. A backrest 34 is movably installed on one side of the seat 33.

[0035] Please see Figure 1 - Figure 4As shown, specifically, a side plate 24 is fixedly installed on the side of the table leg 21 near the base plate 1. A roller 25 is movably installed on one side of the side plate 24, and the roller 25 rolls in the groove 11. A plug rod 26 is movably installed on the side of the side plate 24 near the insertion hole 12 through an opening. The plug rod 26 is inserted into the insertion hole 12. A first-order threaded lifting device 27 is fixedly installed inside the secondary table leg 22. A first-order threaded rod 28 is provided inside the first-order threaded lifting device 27. A first-order threaded strip 29 is fixedly installed inside the table leg 21. The first-order threaded rod 28 and the first-order threaded strip 29 are internally threadedly engaged. A table leg connector is fixedly installed on the side of the secondary table leg 22 near the tabletop 23. 210, a slot 211 is provided on one side of the table leg connector 210, and there are two slots 211. A tabletop connector 212 is fixedly installed on the side of the tabletop 23 near the secondary table leg 22. The tabletop connector 212 is inserted into the inside of the table leg connector 210. A tabletop bolt 213 is movably installed between the tabletop connector 212 and the table leg connector 210 through an opening. A handle 214 is movably installed inside the tabletop connector 212. A spring 215 is connected between one side of the handle 214 and the tabletop 23. A retaining shaft 216 is fixedly installed at the end of the handle 214 near the table leg connector 210. The retaining shaft 216 is inserted into the slot 211.

[0036] As can be seen from the above, by setting the roller 25 to roll inside the groove 11, the table leg 21 can move back and forth on one side of the base plate 1, changing the distance between it and the seat 3 to accommodate children with different arm lengths. At the same time, the insertion rod 26 is inserted into the insertion hole 12 to lock the position of the table leg 21. Through the cooperation of the first threaded lifting device 27, the first threaded rod 28, and the first threaded strip 29, the extension length of the secondary table leg 22 inside the table leg 21 can be adjusted, thereby changing the height of the tabletop 23 to meet the learning needs of different children. The tabletop 23 is connected to the table leg. The cooperation between component 210 and desktop connector 212 allows the top of the secondary table leg 22 to be flipped, thus folding the desktop 23. Under the push of spring 215, the handle 214 will keep the locking pin 216 inserted into the slot 211. Pushing the handle 214 towards the desktop 23 will compress the spring 215, and at the same time, the locking pin 216 will disengage from the slot 211. At this time, the flipping state of the desktop 23 can be manually changed. Releasing the handle 214 will cause the locking pin 26 to re-insert into the slot 211 under the action of spring 215. At this time, the desktop 23 is fixed and cannot be flipped.

[0037] In use, first remove the insert rod 26, then push the table leg 21 back and forth until the distance between the table body 2 and the seat 3 meets the writing requirements. Then insert the insert rod 26 into the corresponding socket 12. Next, adjust the height of the tabletop 23 according to the child's height. Use the corresponding screwdriver to insert into the first threaded lifting device 27 and rotate it. The first threaded lifting device 27 drives the first threaded rod 28 to rotate inside the first threaded strip 29, thereby driving the entire auxiliary table leg 22 and the tabletop 23 to move up and down until the height of the tabletop 23 meets the writing requirements. Use it as needed. You can write your homework on the desktop 23. When you need to fold the desktop 23, first press the handle 214 so that the handle 214 is close to the desktop 23. The spring 215 is in a compressed state. At the same time, the locking pin 216 will also move away from the upper locking slot 211. The desktop 23 can then be flipped downwards. After folding the desktop 23, you can release the handle 214. The handle 214 will return to its original position under the action of the spring 215. At the same time, the locking pin 216 will be inserted into the lower locking slot 211, and the desktop 23 will be locked in the folded state.

A swing bolt 318 is provided between the backrest 34 and the swing groove 317.

[0041] As can be seen from the above, the working principle of the No. 2 threaded lifting device 35 is the same as that of the No. 1 threaded lifting device 27, and both belong to existing technology, so we will not go into details here. This structure can be used to adjust the height of the seat 33, which can be flexibly adjusted according to the height of the child. Loosening the seat leg bolts 39 can easily change the angle of the seat 33, thereby meeting different sitting posture requirements. At the same time, when adjusting the angle of the seat 33, the two support bolts 314 need to be loosened first, and then the support bolts 314 need to be tightened after the adjustment is completed. The support rod 313 can provide stable support for the seat 33, and the support bolts 314 can slide inside the adjustment groove 311. After the adjustment is completed, they need to be tightened to meet the stable support of the seat 33 at different angles. The backrest 34 can change the angle on one side of the swinging part 315. The backrest bolts 316 and swing bolts 318 need to be loosened first. The swing groove 317 is used to adapt to the position change of the swing bolts 318. After the adjustment is completed, the backrest bolts 316 and swing bolts 318 need to be tightened.

[0042] In use, first insert a special screwdriver into the No. 2 threaded lifting device 35 inside the secondary chair leg 32 to adjust the height of the seat 33. Then loosen the chair leg bolt 39 and support bolt 314 and manually adjust the angle of the seat 33. Next, tighten the chair leg bolt 39 and support bolt 314 to lock the angle of the seat 33. Then loosen the backrest bolt 316 and swing bolt 318 and manually adjust the angle of the backrest 34. Finally, tighten the backrest bolt 316 and swing bolt 318 to lock the angle of the backrest 34.
