Detailed Description

The following description is of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, but is intended to cover any modifications, equivalents, improvements, etc. within the spirit and principles of the present invention.

The following examples are to be understood as being a separate representation of part of the novel structures or methods and also as being a combination of the examples with each other to illustrate the meaning of the novel structures or methods of greater scope.

Example 1

The split type schoolbag comprises a schoolbag body, wherein the schoolbag body comprises a first schoolbag 1 and a second schoolbag 2 which are arranged up and down, the side faces of the first schoolbag 1 and the side faces of the second schoolbag 2 are connected through a fastening mechanism 3, and the two sides of the front ends of the first schoolbag 1 and the two sides of the front ends of the second schoolbag 2 are connected through braces 4 respectively.

Example 2

As shown in fig. 1, the front end of the first schoolbag 1 is configured to abut against the shoulder and back of the wearer, the front end of the second schoolbag 2 is configured to abut against the waist of the wearer, and the strap 4 is of a strap structure with an adjustable length (as shown in fig. 1-3, the strap structure with an adjustable length is of the prior art, and is not described in detail).

In this embodiment, as shown in fig. 1, the shoulder and waist of the wearer are respectively contacted with the front ends of the first schoolbag and the second schoolbag, so that the mode that the schoolbag body of the original integral schoolbag is contacted with the shoulder and back only is changed into the mode that the schoolbag body is contacted with the shoulder and back only and also contacted with the waist, and therefore the wearer can bear the weight of the schoolbag body through the chest, the shoulder and the waist at multiple points, and the pressure is dispersed.

More importantly, the first schoolbag and the second schoolbag have a mutually matched stress relationship, and the fact that on one hand, the second schoolbag transmits tension through the braces, and further the downward tension of the first schoolbag is relieved through the counterweight principle, and the first schoolbag also transmits tension through the braces, and further the forward and upward tension of the second schoolbag is improved. Because the weight of the first schoolbag is reduced due to the downward pressure of the second schoolbag and the second schoolbag is pulled upwards by the first schoolbag, a wearer can feel more comfortable, and meanwhile, because the second schoolbag is pulled forwards and upwards by the first schoolbag, the second schoolbag can be propped against the waist of a wearer, and a good shaping effect is achieved.

Example 3

As shown in fig. 1, 2 and 3, the fastening mechanism 3 includes a male buckle 31 and a female buckle 32, and the female buckle and the male buckle are respectively and fixedly connected with the side surfaces of the first schoolbag 1 or the second schoolbag 2.

In this embodiment, as shown in fig. 1-3, the male buckle and the female buckle are common techniques, and a buckle mechanism capable of realizing the above functions may be selected during manufacturing.

Example 4

As shown in fig. 3, the outer surface of the back strap 4 is provided with a marking line 10 for marking the telescopic length of the back strap. The sign line is arranged in the back of the backpack, so that the backpack can conveniently adjust the braces on the two sides to be equal in length, and uneven stress on the two shoulders is avoided. As shown in fig. 3, the length of a conventional harness can be adjusted by pulling down the lower harness head, and the extension and retraction width of the harness can be quickly recognized by referring to the mark line 10 on the harness.
