Description

Technical Field

[0001] The utility model relates to the field of backpack accessories, and more specifically, to a spine-protecting backpack. Background Art

[0002] Backpacks are items that people often use in their daily lives. People can use backpacks to carry books and other scattered items when going out, which is simple and convenient.

[0003] Current backpacks are equipped with a support plate for support. However, since the support plate does not fit the back of the human body, people feel less comfortable when wearing the backpack. In addition, some backpacks with padded cushions fit the spine, but the cushions are not breathable. Especially in the hot summer, people feel less comfortable wearing the backpack due to the lack of air permeability and heat dissipation.

[0004] Therefore, it is necessary to propose a spine protection backpack that solves the above problems. Utility Model Content

[0007] The support plate is provided with a soft pad for protecting the spine, and the soft pad is in a "U" shape;

[0008] An upper air-avoiding groove is provided on the upper end surface of the soft pad, and a lower air-avoiding groove is provided on the lower end surface of the soft pad. The upper air-avoiding groove and the lower air-avoiding groove are staggered with each other. Since the upper air-avoiding groove and the lower air-avoiding groove are staggered with each other, heat dissipation and air conduction can be facilitated by the staggered arrangement of the upper air-avoiding groove and the lower air-avoiding groove. Since the soft pad is in a "U" shape, after the soft pad is set, it can fit the human spine better, making people more comfortable after carrying the backpack.

[0009] Furthermore, air guide holes are provided between adjacent upper air-avoiding grooves, and the air guide holes are connected to the lower air-avoiding grooves. Through the air guide holes, air conduction and heat dissipation on the back can be better achieved.

[0010] Furthermore, the support plate is provided with a waist protection bulge, and an air guide groove is provided on the waist protection bulge. Since the support plate is provided with the waist protection bulge, it can protect the waist, and the setting of the air guide groove can facilitate ventilation.

[0011] Further, a cushion groove is provided on the back surface of the cushion, and an air guide communication groove is provided on the cushion. When the cushion is arranged on the support plate, the cushion groove on the back surface of the cushion is pressed against the lumbar support bump on the support plate, and the air guide communication groove is communicated with the air guide groove on the lumbar support bump. Since the air guide communication groove is communicated with the air guide groove on the lumbar support bump, it is more convenient for ventilation and heat dissipation.

[0012] Furthermore, the support plate is made of plastic material. In practical applications, the support plate can also be made of other materials, which are all within the protection scope of the present utility model.

[0013] Further, the cushion is made of EVA material. The cushion made of EVA material makes the backpack more comfortable to use.

[0014] Furthermore, the hardness of the cushion is between 28-30 degrees. In practical applications, the hardness of the cushion can be selected according to needs, which are all within the protection scope of the present utility model.

[0015] Compared with the prior art, the beneficial effects of the technical solution of the present utility model are:

[0016] In the spinal protection backpack disclosed by the present utility model, since the upper clearance groove and the lower clearance groove are arranged staggeredly, the staggered arrangement of the upper clearance groove and the lower clearance groove facilitates heat dissipation and air conduction. And since the cushion is in a "U" shape, after the cushion is arranged, it can fit the human spine better, making people more comfortable when carrying the backpack. Description of the Drawings
