DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0034] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0035] like Figure 1-2 As shown in the figure, the utility model provides a variable school bag, including a body 1, a first limiting insert 2 is arranged on the first side 1-1 of the body, a first limiting ring 3 is arranged on the first limiting insert 2; a first shoulder strap 4, a second limiting ring 5 is arranged on the first shoulder strap 4; and a second shoulder strap 6 is also provided vertically symmetrically on the carrying side of the body. The second shoulder strap 6 can be easily used to carry the backpack on both shoulders.

[0036] like Figure 3-4 As shown, the first end of the first shoulder strap 4 is connected to the second side 1-2 of the body, the end of the first shoulder strap passes through the second limiting ring 5 and the first limiting ring 3 in sequence, and then passes back through the second limiting ring 5 and then closes at the end around the second limiting ring 5, the second limiting ring 5 can move between the connection between the first shoulder strap 4 and the second side 1-2 of the body to the first limiting ring 3, and the movement of the second limiting ring 5 can realize the folding or elongation of the first shoulder strap 4. Through the setting of the first shoulder strap 4, it can be switched to single-shoulder carrying or hand-carrying portable use according to actual use needs.

[0037] like Figure 5-6 As shown, in order to increase the overall storage space of the backpack, an auxiliary bag 7 is further provided on the side away from the second shoulder strap 6, so that different kinds of articles can be stored in the main body 1 or the auxiliary bag 7 in different categories, avoiding placing all articles, especially small and scattered articles, in one storage space and wasting time searching for them when they are needed.

[0038] In order to make the accessory bag 7 applicable to different usage scenarios, the accessory bag 7 is detachably connected to the main body 1 via a first opening and closing component, and the detachable connection method is a zipper or a magnetic buckle.

[0039] When connected by a zipper, the zipper is composed of a second belt body vertically placed on both sides of the auxiliary bag 7 and a first belt body correspondingly arranged on the side of the main body 1 away from the second shoulder strap 6.

[0040] When connected by magnetic buckle, at least one female buckle is arranged on the back side of the main body, and at least one male buckle is arranged on the side of the auxiliary bag 7 close to the female buckle, and the female buckle and the male buckle are pressed and buckled.

[0041] like Figure 7 As shown, at least one second limiting plug 7-1 is arranged on the lower side of the carrying side of the accessory bag, and at least one third limiting plug 7-2 is arranged on the upper side of the carrying side of the accessory bag. The accessory bag also includes at least one third shoulder strap 7-3 that can be stored in the accessory bag. The third shoulder strap 7-3 can be connected with the second limiting plug 7-1 and / or the third limiting plug 7-2 to realize single-shoulder or double-shoulder carrying of the accessory bag 7. By arranging a hook at the first and second ends of the third shoulder strap, the hook can pass through the second limiting plug 7-1 and / or the third limiting plug 7-2 and be connected with the hook buckle, thereby realizing the separate use of the accessory bag 7, thereby improving the use efficiency of the main body 1 and / or the accessory bag 7 in different usage scenarios.

[0042] In order to achieve the portability of the entire backpack, a hand grip device 8 is set in parallel with the first shoulder strap 4 at the central position between the first side 1-1 of the main body and the second side 1-2 of the main body, so as to avoid the situation where the backpack is unevenly stressed and easily damaged when using the first shoulder strap 4 or the second shoulder strap 6 to carry the bag with one hand, and at the same time, the portability of the bag with one hand can be improved through the hand grip device 8.

[0043] In order to increase the stability of the backpack when it is carried on both shoulders, so as to facilitate different application scenarios such as walking, running, and jumping, at least one pair of openable and closable chest straps 9 are laterally symmetrically or cross-arranged on the second shoulder strap 6, one end of the chest strap 9 is respectively connected to the second shoulder strap 6, and the other end of the chest strap 9 is connected to the chest strap 9 through a second opening and closing component, thereby appropriately increasing the restraint between the backpack and the user, preventing the backpack from colliding up and down due to inertia during running and jumping, which brings a bad user experience.

[0044] Similarly, in order to make the backpack suitable for more usage scenarios, such as when the user carries the backpack out at night in a dark external environment, reflective strips are provided on the side of the second shoulder strap 6 and / or the auxiliary bag 7 away from the main body 1 to improve safety, so that the backpack mark can be easily found in a dark environment, thereby protecting the user's personal safety.

[0045] In order to further adapt to more usage scenarios, the main body 1 and the auxiliary bag 7 can be connected through a first opening and closing component that is vertically symmetrically arranged. The first opening and closing component is extended in the vertical direction of the bottom support surface of the main body 1 and / or the auxiliary bag 7 and has a second length in the extension direction, and the second length is not greater than the first length.

[0046] The first opening and closing component includes a first belt body symmetrically arranged on both sides of the front surface of the main body and a second belt body symmetrically arranged on both sides of the back negative side of the auxiliary bag. The first belt body and the second belt body are connected in a chimeric manner, so that when the auxiliary bag 7 is attached to the main body 1, the whole school bag and each bag body can be stably connected, ensuring that the front surface of the main body 1 and / or the back negative side of the auxiliary bag 7 are uniformly stressed, thereby avoiding damage to the main body 1 and / or the auxiliary bag 7. It can also be achieved that when the school bag is used as a whole, no matter the user is walking, running, jumping, etc., the center and center of gravity of the whole school bag and each bag body can be kept from shifting easily, thereby achieving a good user experience.

[0047] The overall appearance of the school bag is optimized, and a flap is provided on the subsidiary bag 7. One side of the flap is fixedly connected to the subsidiary bag 7. After the flap is flipped over, it can cover part or all of the front surface of the subsidiary bag 7. The other side of the flap is connected to the front surface of the subsidiary bag 7 by means of magnetic buckles, Velcro, buttons, etc., thereby improving the user experience and meeting the fashion needs of different users.

[0048] The contents described in this specification are merely examples of the present invention. Technicians in the technical field to which the present invention belongs can make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the contents of the present invention specification or exceed the scope defined by the claims, they should all fall within the protection scope of the present invention.
