Further, the back plate is divided into an upper part and a lower part, the upper part of the back plate and the backpack schoolbag body are combined into a whole, and the lower part of the back plate and the waist protecting belt are combined into a whole.

Furthermore, the waist protecting belt is divided into five parts, and the middle section of the waist protecting belt is an EVA or elastic cloth-wrapped sponge or sandwich elastic soft net cloth section; elastic cloth or elastic bands or elastic band sections are arranged on two sides of the middle section; the front surfaces of the two end sections of the waist protecting belt are provided with magic tape rough surfaces, and the back surfaces of the two end sections of the waist protecting belt are provided with magic tape hook surfaces.

Furthermore, a hole position or a space is arranged in the back plate for inserting the supporting piece; the supporting piece and the spring penetrate through a hole position or a space in the back plate to be fixed; the spring is against the top of the back plate.

Furthermore, the supporting pieces are a plurality of elastic rods or metal rods or fiber plates, springs at two ends of each supporting piece are plugged by caps, and the caps combine the supporting pieces into a group.

Furthermore, the tail end of the elastic belt is provided with a magic tape or a buckle for adjusting the backward pulling force of the shoulder belts so that the back of the human body is tightly attached to the back plate.

After the proposal is adopted, the utility model transfers the weight of the backpack from the shoulder arm part to the waist or the hip part, and lowers the gravity center. The damage of gravity vibration to the spine is reduced; meanwhile, the shoulder and arm parts, the spine and the back are also ensured to be straight.

Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

As shown in fig. 1-7, the backpack for preventing humpback, reducing weight, cushioning and reducing pressure comprises: the back plate 1, the back plate 1 can be divided into an upper part and a lower part, can also be connected into a whole, and can also be directly made of an integrated material or sheet material, such as EVA, PE cotton, or sandwich elastic soft mesh cloth.

In the embodiment, the upper part of the back plate 1, the double shoulder belts 2 and the schoolbag body 3 are integrated. The back plate 1 is provided with a support member therein, the support member may be a plurality of elastic rods or metal rods or fiber plates, fig. 7 illustrates two groups of elastic rods 4 (only one group is shown in the figure, and the other group has the same structure as the one group), and the upper and lower ends of each group of elastic rods 4 are provided with spring groups 5 formed by springs. Holes or spaces are arranged in the back plate 1, and each group of elastic rods 4 can be inserted; each group of elastic rods 4 and spring groups 5 penetrate through the hole positions on the upper part of the back plate 1 to be fixed. The spring groups at the two ends of each group of elastic rods 4 are blocked by caps 12, and the caps 12 combine each group of elastic rods 4 into one group to distribute and balance the stress of the springs. The spring pack 5 is against the top of the back plate 1.

Specifically, the elastic rod 4 can be a glass fiber rod, an aluminum tube or a light metal plate. When the backpack body bears a load, the upper part of the back plate 1 presses down on the spring sets 5 at the upper and lower ends of the elastic rod 4 in the back plate 1.

The lower part of the back plate 1 and the waist support band 6 may be one piece.

Specifically, the waist protecting belt 6 can be divided into five parts, and the middle section of the waist protecting belt 6 can be EVA, elastic cloth wrapped sponge, sandwich elastic soft mesh cloth and the like; the function is the weight of the backpack and the buffer protection area of the waist.

The second and fourth sections of elastic bands 10 of the waist protecting band can be elastic cloth, elastic bands or elastic bands; the front surfaces of the two end sections 11 of the waist support are hook and loop surfaces 7.

The weight 3 of the schoolbag body is transferred to the middle of the waist protecting belt 6, and the vibration generated by the earth core suction force is buffered and reduced by the cooperation of the spring 5 and the elastic band 10, so that the adverse effect of the vibration and the pressure on the spine is reduced.

The two ends of the waist protecting belt 6 are provided with magic tapes or buckles 7 for adjusting different waist sizes.

The inner sides of the double shoulder straps 2 are provided with elastic belts 8, the elastic belts 8 are fixed in front of the waist protecting belt 6 by surrounding the waist from left and right armpits, passing through the back and then reaching the periphery of the waist protecting belt 6, and the tail ends of the elastic belts 8 are provided with magic tapes or buckles 9 for adjusting the pulling force of the double shoulder straps 2.

Specifically, the back of the human body is tightly attached to the back plate 1, and a plurality of elastic rods 4 arranged in the back plate 1 form a row, such as a hard plate. The elastic band 8 pulls the double shoulder belts 2 backwards to enable the shoulder arms to be pulled back to be parallel to the back of the human body and the back plate 1, so that the back is straight and the chest is lifted, and the humpback is prevented.

While the foregoing description shows and describes the preferred embodiments of the present invention, it is to be understood that the invention is not limited to the forms disclosed herein, but is not intended to be exhaustive or to exclude other embodiments and may be used in various other combinations, modifications, and environments and is capable of changes within the scope of the inventive concept as expressed herein, commensurate with the above teachings, or the skill or knowledge of the relevant art.
