Description

Technical Field

[0001] The utility model relates to the technical field of school bags, in particular to a school bag with a buffer shoulder strap and a waist support. Background Art

[0002] Backpacks are an important carrying tool and are widely used in daily life. During daily use, a large number of items are often loaded into the backpack, which increases the weight. The shoulder straps of current backpacks are directly fixed to the backpack body. The weight acts directly on the shoulders, which brings great pressure to the shoulders. Carrying the backpack for a long time will make the shoulders sore and uncomfortable. In particular, the ups and downs caused by walking will cause the weight of the backpack to fall down again and again and impact the shoulders, further increasing the pressure on the shoulders.

[0003] A search revealed a Chinese patent with publication number CN206866866U, which discloses a backpack with a cushioning function. The backpack comprises a shoulder bag and two shoulder straps symmetrically arranged and fixed to the back of the bag. The backpack also comprises two first fabric layers and a second fabric layer. The two first fabric layers are symmetrically arranged and fixed to the back of the bag, and the first fabric layers and the back of the bag enclose a first filling cavity. A first airbag is disposed within the first filling cavity. The first fabric layer is also provided with a first one-way air inlet valve in communication with the first airbag. The second fabric layer is fixed to the back of the bag, and the second fabric layer and the back of the bag enclose a second filling cavity. A second airbag is disposed within the second filling cavity. The second fabric layer is also provided with a second one-way air inlet valve in communication with the second airbag. A first breathable mesh layer and a second breathable mesh layer are respectively fixed to the outer walls of the first and second fabric layers. This utility model utilizes airbags to achieve cushioning, providing a long-lasting and effective cushioning effect.

[0004] However, the above design still has some shortcomings. In the above design, a first air bag and a second air bag filled with gas are arranged on the back of the backpack to provide a buffering effect between the backpack and the human body. However, since the buffering effect of the first air bag and the second air bag is not good, when the weight in the backpack is heavy, it is difficult to achieve the buffering effect by relying solely on the air bags, which affects people's comfort in use.

[0005] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application, and should not be regarded as an admission or any form of implication that the information constitutes the prior art already known to ordinary technicians in this field. Utility Model Content

[0028] See also Figure 1-6 The utility model provides an embodiment of a school bag with a cushioning shoulder strap and a waist support, comprising a backpack body 1, a connecting block 7 fixedly connected to the rear end of the backpack body 1, a shoulder strap 5 fixedly connected to the rear end of the connecting block 7, a first soft rubber filling bag 4 fixedly connected to the inner side of the shoulder strap 5, a soft rubber pad 9 fixedly connected between two adjacent connecting blocks 7 above, a plurality of second soft rubber filling bags 10 fixedly arranged on the rear end of the soft rubber pad 9, a plurality of soft rubber strips 8 fixedly arranged on the bottom of the soft rubber pad 9, a telescopic rod 14 fixedly connected to the bottom of the telescopic rod The outer wall of the backpack 14 is provided with a spring 13, and the number of the springs 13 and the telescopic rods 14 are both six. The telescopic rods 14 are telescopic hollow cylindrical rods made of rolled metal strips. Side bags 3 are fixedly connected to both sides of the backpack body 1, and a handle 2 is fixedly connected to the top of the backpack body 1. The rear end surface of the telescopic rods 14 is fixedly connected to the waist support frame 11, and the inner side of the waist support frame 11 is fixedly connected to the protective pad 12. The interior of the first soft plastic filling bag 4 and the second soft plastic filling bag 10 are filled with an appropriate amount of artificial down, and the down content of the artificial down is not less than 80%;

[0029] Specifically, such as Figure 1、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, during use, the user can provide a cushioning effect between the backpack body 1 and the back of the human body through the mutual cooperation of multiple second soft rubber filling bags 10, and can support the user's waist through the mutual cooperation of the waist support frame 11 and the protective pad 12 during the wearing of the backpack body 1. At the same time, during use, the waist support frame 11 will cause the spring 13 to deform, and the elasticity of the spring 13 can be used to effectively reduce the impact force generated by the backpack body 1 on the user's waist, thereby improving comfort. The provision of the first soft rubber filling bag 4 can not only avoid direct contact between the shoulder strap 5 and the user's shoulder, but the added artificial down can effectively reduce the force exerted on the user's shoulder, which can further improve comfort. The problem of providing a cushioning effect between the backpack and the human body by providing a first airbag and a second airbag filled with gas on the back of the backpack is solved. However, due to the poor cushioning effect of the first airbag and the second airbag, when the weight in the backpack is large, it is difficult to achieve a cushioning effect by relying solely on the airbag, which affects people's comfort.

[0030] The four corners of the bottom of the backpack body 1 are fixedly connected with second Velcro 16, and the number of the second Velcro 16 is four. The bottom of the second Velcro 16 is pasted with the first Velcro 15, and the bottom of the first Velcro 15 is fixedly connected with the wear-resistant block 6;

[0031] Specifically, such as Figure 3 and Figure 6 As shown, during use, the setting of the wear-resistant block 6 can slow down the wear of the bottom of the backpack body 1, which not only improves the aesthetics of the backpack body 1, but also extends the use time of the backpack body 1. Through the mutual cooperation of the first Velcro 15 and the second Velcro 16, the wear-resistant block 6 is easy to disassemble, assemble and replace, thereby making it more convenient for users to use.

[0032] Working principle: In this application, during use by the user, the mutual cooperation of multiple second soft rubber filling bags 10 can provide a buffering effect between the backpack body 1 and the human back, and during the wearing process of the backpack body 1, the mutual cooperation of the waist support frame 11 and the protective pad 12 can support the user's waist. At the same time, during use, the waist support frame 11 will cause the spring 13 to deform, and the elasticity of the spring 13 can be used to effectively reduce the impact force generated by the backpack body 1 on the user's waist, thereby improving comfort. The provision of the first soft rubber filling bag 4 can not only prevent the shoulder strap 5 from directly contacting the user's shoulder, but the added artificial down can effectively reduce the force exerted on the user's shoulder, which can further improve comfort. Secondly, the provision of the wear-resistant block 6 can reduce the wear of the bottom of the backpack body 1, which not only improves the aesthetics of the backpack body 1, but also extends the service life of the backpack body 1. The mutual cooperation of the first Velcro 15 and the second Velcro 16 makes it easy to disassemble and replace the wear-resistant block 6, thereby making it more convenient for users to use.
