A few days ago, China Consumer Association released a student schoolbag evaluation results show that there are obvious differences in the protection function and use function of schoolbags on the market. When parents choose schoolbags for their children, which one should they choose? Can they choose pull-out schoolbags?
An orthopedic expert from Southwest Hospital suggested that backpacks should be the first choice. "Just like a good mountaineering bag, the material used on the back is thick and not easy to deform. Pupils' schoolbags should follow this principle. Parents can not adjust the strap of schoolbag too long, the center of gravity should just fall in lumbosacral department For the pull rod schoolbag, this expert thinks that if the pull rod length of the pull rod schoolbag is not suitable, it will cause damage to the child. "If a child is used to pulling a schoolbag with one hand, a long time will cause uneven force on both sides of the spine。”
Experts warn that both sides of the spine are like scales. If only one side is applied, the spine will tilt and bend to one side in the long run. In childhood, as the spine is still in the development stage, it should be ensured that both sides are evenly stressed, so the backpack is the best choice。
In addition, he also reminded citizens that children's schoolbags should not be too heavy, "no matter how well protected, if their schoolbags are too heavy, they will still have an impact。”
We have also learned that, generally speaking, there are relatively more students who change one schoolbag in a school year; secondly, they change one schoolbag every semester; at present, there are very few students who only change their schoolbags for two years or more. The primary school teacher suggested, "it's not necessary to change it every semester, unless the schoolbag is worn out。”
We arranged a key point about the purchase of schoolbags, hoping to help you later: straps: pay attention to the width and thickness of the shoulder strap, the suitability of interlayer foam pad, arc, and soft hardness. Because the structural design of the strap is reasonable or not, it is related to the comfort of backpack users。
Backpack cushion: good backpack cushion should have foam pad, thickness, soft hardness should be appropriate, so that users can play a good role in protecting the back. If a strip cushion is added on both sides of the bag back pad, it is conducive to air circulation and increase comfort。
