DETAILED DESCRIPTION

[0022] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference Figure 1-Figure 6As shown, the utility model provides a spine-protecting schoolbag with a decompression carrying function, including a schoolbag body 1, a first storage cavity 11 is arranged on the top of one side of the schoolbag body 1, a second storage cavity 12 is also arranged on the schoolbag body 1 near the first storage cavity 11, and a third storage cavity 13 is also arranged on both sides of the outside of the schoolbag body 1. The third storage cavity 13 is convenient for quickly storing and accessing items, such as a water bottle, an umbrella, etc. A back pad assembly 16 for dispersing the force on the back is also arranged on the side of the schoolbag body 1 away from the first storage cavity 11. The back pad assembly 16 disperses the force on the back, improves the carrying comfort, and has an additional decompression function. A shoulder strap system 14 is arranged on the schoolbag body 1 near the back pad assembly 16. The shoulder strap system 14 is used to carry the schoolbag on the shoulder, and the shoulder strap system 14 adopts an ergonomic design to reduce the pressure on the shoulder. The back pad assembly 16 includes a first back pad 161 arranged on the backpack body 1 and symmetrically relative to the center position of the backpack body 1, the back pad assembly 16 also includes a second back pad 162 arranged between the two first back pads 161 and close to the bottom position of the backpack body 1, and the back pad assembly 16 also includes a third back pad 163 arranged between the back pad assembly 16 and close to the top position of the backpack body 1. A guide groove 164 for airflow is formed between the two first back pads 161. The guide groove 164 allows airflow to pass through, which helps to keep the back ventilated when carrying and reduce the feeling of stuffiness. When the user carries the spine protection backpack, the strap system 14 distributes the weight of the backpack to the shoulders. The multiple back pads of the back pad assembly 16 can disperse the force on the back, reduce single-point pressure, and thus improve the comfort of carrying. The different positions and shapes of the first back pad 161, the second back pad 162 and the third back pad 163 are designed to better fit the back curve and provide comprehensive support. The design of the guide groove 164 allows air to circulate on the back, which helps to reduce the stuffiness caused by carrying the backpack for a long time.

[0024] A guide groove 164 is formed between the two first back pads 161. When the backpack body 1 is carried on the back of the user, the design of the back pad assembly 16 ensures that the backpack body 1 does not cling to the user's back, but achieves ventilation and heat dissipation through the guide groove 164, thereby improving the comfort of the backpack. In addition, by reasonably designing the layout of the first back pad 161, the second back pad 162 and the third back pad 163, the force on the user's back can be effectively dispersed, further improving the comfort of the backpack.

[0025] The shoulder strap system 14 includes a main shoulder strap 141 connected to the top of the backpack body 1 and a secondary shoulder strap 142 connected to the bottom of the backpack body 1. The main shoulder strap 141 is in an "S" shape. This shape design conforms to the principle of ergonomics and can better fit the user's shoulder curve, disperse the shoulder force, and reduce shoulder fatigue and discomfort caused by long-term carrying. One end of the main shoulder strap 141 is connected to a buckle male head 1411, and one end of the secondary shoulder strap 142 is connected to a buckle female head 1421. The buckle male head 1411 can be inserted into the buckle female head 1421 to connect the main shoulder strap 141 and the secondary shoulder strap 142 together.

[0026] The shoulder strap system 14 also includes a connecting belt 1414 and an adjusting belt 1415 connected to the end of the main shoulder strap 141 away from the buckle male head 1411. One end of the connecting belt 1414 is connected to a connecting piece 1416. The adjusting belt 1415 is wrapped around the connecting piece 1416 to adjust the distance of the main shoulder strap 141. The length of the main shoulder strap 141 can be easily adjusted by simply tightening or loosening the adjusting belt 1415. The length of the shoulder strap can be flexibly adjusted according to personal height, body shape and carrying habits to ensure the stability and comfort of the spine protection backpack when carried.

[0027] The shoulder strap system 14 also includes support strips 1412 arranged on the two main shoulder straps 141, and the two support strips 1412 are also connected to a chest strap 143 of adjustable length. The main shoulder straps 141 are also provided with a third reflective strip 1413 for reflection. At night or in a dimly lit environment, the third reflective strip 1413 can reflect the surrounding light to improve the visibility of the spine-protecting backpack, thereby increasing safety when walking. The third reflective strip 1413 is made of highly reflective material and can emit bright light under light to attract the attention of pedestrians and vehicles around. The shoulder strap system 14 also includes a waist belt 144 of adjustable length arranged at the bottom of the backpack body 1.

[0028] The chest strap 143 is arranged on the main shoulder strap 141 and is used to be fixed on the chest of the user. At the same time, the backpack body 1 is also connected with a waist belt 144 with adjustable length, which is used to be fixed on the waist of the user. This design of double chest and waist belt fixing plays a double role of unloading and reducing load, and improves the carrying stability of the spine protection backpack.

[0029] The backpack body 1 is provided with a plurality of accordion compartments 17 for storing books, and the accordion compartments 17 are also provided with elastic bands 18 to prevent the books from tilting. The pencil case body 2 is stored between the accordion compartments 17 and the elastic bands 18. The backpack body 1 is also provided with third storage cavities 13 on both sides, and the third storage cavity 13 is provided with a second reflective strip 131 for reflection. The second reflective strip 131 can reflect the surrounding light at night or in a dimly lit environment, thereby improving the visibility of the spine-protecting backpack and increasing the safety when walking. The outside of the second storage cavity 12 is provided with a first reflective strip 121 for reflection, and the edge of the second storage cavity 12 is also provided with a light-emitting light strip 122, which is annular. The backpack body 1 is also provided with a handle 15, which is convenient for the user to carry the spine-protecting backpack by hand when the shoulder strap is not used. The handle 15 is usually made of a sturdy and comfortable material, such as a nylon strap or a plastic handle, to ensure that the user can easily lift and carry the back-protecting backpack.

[0030] Working principle: When in use, first insert the male buckle 1411 into the female buckle 1421 to firmly connect the main strap 141 and the secondary strap 142. Then, the user puts the backpack body 1 on his back. At this time, the chest strap 143 can fit and be fixed on the user's chest, and the waist belt 144 can be fixed on the user's waist. This design of chest and waist double belt fixation effectively plays a double role of unloading and reducing load, making it easier to carry. At the same time, the back of the backpack body 1 is designed with a back pad assembly 16, including a first back pad 161, a second back pad 162 and a third back pad 163. A reasonable layout is formed between the first back pad 161, the second back pad 162 and the third back pad 163, so that the backpack body 1 will not be close to the user's back. In particular, the guide groove 164 formed between the two first back pads 161 can effectively ventilate and dissipate heat, further improving the comfort of the backpack. In addition, through the reasonable design of the first back pad 161, the second back pad 162 and the third back pad 163, the force on the user's back can be dispersed, making the back more evenly loaded, and further improving the comfort of the spine-protecting schoolbag. When the surrounding light shines on the spine-protecting schoolbag, the first reflective strip 121, the second reflective strip 131 and the third reflective strip 1413 arranged on the surface of the spine-protecting schoolbag can reflect the surrounding light to form a 360-degree reflective warning, effectively reminding the surrounding personnel to pay attention, thereby protecting the safety of the child. In addition, the backpack body 1 is also designed with an adjustable main strap 141. By pulling the adjustment belt 1415, the length of the main strap 141 can be easily adjusted to suit students of different heights. An accordion compartment 17 is also provided inside the backpack body 1 to facilitate the classification and access of books. At the same time, through the action of the elastic band 18, the books can be effectively prevented from tilting in the spine-protecting schoolbag, keeping the inside of the spine-protecting schoolbag neat and orderly.
