Description

Technical Field

[0001] The utility model relates to the technical field of school bags, in particular to a multifunctional backpack with adjustable shoulder straps. Background Art

[0002] Backpack refers to the general term for bags that are carried on the back when going out. With the continuous improvement of people's living and consumption standards, backpacks have become an indispensable item around people, and people have higher and higher requirements for the practicality and comfort of backpacks. The specifications of backpacks produced by manufacturers are generally fixed, and the skeletons of users are different, so conventional backpacks with fixed straps are not suitable for all users; in addition, when a conventional backpack is carried on a person's back, the stress point is concentrated on the shoulder, and other parts of the back are almost not stressed, so the shoulder is very easy to fatigue. In the long run, it will affect the user's physical health, especially affecting primary and secondary school students in their developmental period.

[0003] For example, the patent document with patent application number CN202010141549.8 discloses a directly shaped and highly breathable backpack, which connects the shoulder straps by sliding them in a strip sliding groove. However, this method cannot fix the shoulder straps, and the shoulder straps are prone to continuous displacement during use, making it difficult for users to adapt.

[0004] For another example, the patent document with patent application number US1964369117 discloses a backpack with reinforced shoulder straps, in which the shoulder straps are connected by setting a plurality of pairs of holes, and the holes and the buckles are directly connected point-to-point, which reduces the contact area between the shoulder straps and the bag body and increases the pressure between the shoulder straps and the bag body, which easily leads to deformation of the connection between the shoulder straps and the bag body, and may eventually damage the shoulder straps. Moreover, with this structure, when the shoulder straps are connected to the holes or removed from the holes, the buckles need to be opened, so the installation and removal of the shoulder straps are inconvenient and inefficient. Summary of the invention

[0005] The utility model provides a multifunctional backpack with adjustable shoulder straps. A plurality of hook sheets are provided to accommodate the hooks, and insertion holes are formed between the sheets and the bag body, so that the shoulder straps can be adjusted according to the shoulder width of the user. The backpack is simple to operate, easy to use, and has a long service life.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is: a multifunctional backpack with adjustable shoulder straps, comprising a bag body and shoulder straps, the lower ends of the shoulder straps are connected to the bag body, and at the upper end of the bag body are provided with more than two sheets extending in the lateral direction of the bag body, the two sides of the sheets are connected to the bag body, an insertion hole is formed between the middle part of the sheets and the bag body, and a hook is connected to the upper end of the shoulder strap; the hook comprises a hook body and a hook connector, one end of the shoulder strap is connected to the hook body, the bottom end of the hook body and the bottom end of the hook connector are connected through a bottom plate, a slot is formed between the hook body and the hook connector, the hook connector is inserted into the slot from the lower end of the slot so that the sheet is located in the slot to realize the connection between the shoulder strap and the bag body, and the bottom plate is located below the sheet.

[0007] The above structure, by providing multiple sheets and forming an insertion hole between the sheet and the bag body, can adjust the shoulder strap according to the shoulder width of the user. The operation is simple and easy to use. The hook and buckle connector is inserted into the insertion hole so that the sheet is located in the slot to achieve the adjustment of the shoulder strap. When in use, the sheet moves downward due to the center of gravity of the bag body. The sheet is restricted by the bottom plate so that the sheet can be restricted in the slot. The structure is simple, and the sheet is restricted in the slot as a whole. Therefore, the contact area between the sheet and the hook is large. Therefore, the sheet is not easy to be deformed and damaged, and the service life is long. In addition, the hook and buckle connector can be limited by the two sides of the insertion hole. Therefore, when the hook and buckle connector is inserted into the insertion hole, the hook is not easy to swing in the insertion hole, and it is more reliable to use.

[0008] Furthermore, the two or more sheets are an integral sheet, and sewing lines connected to the bag body are provided between adjacent sheets.

[0009] The above arrangement connects the sheets by sewing, and the structure is simple and reliable.

[0010] Furthermore, the whole sheet is a braided belt.

[0011] The above arrangement forms a sheet body by weaving a belt, and the structure is simple and reliable.

[0012] Furthermore, a connecting hole is provided at the upper end of the hook body, and the upper end of the shoulder strap is connected to the connecting hole.

[0013] The above arrangement facilitates the connection of the shoulder straps through the connection holes.

[0014] Furthermore, the package body includes a front package body and a rear package body, the front package body and the rear package body are connected by a connecting belt, and the sheet body is arranged on the rear package body.

[0015] Furthermore, the front package body includes a front package body and front side panels arranged on both sides of the front package body, and the rear package body includes a rear package body and rear side panels arranged on both sides of the rear package body, and the front side panel and the rear side panel on the same side are connected by a zipper.

[0016] The above arrangement is to provide a bag body with a front bag body and a rear bag body, and connect the front bag body and the rear bag body with a zipper, so that the bag body can be unfolded when the zipper is opened, thereby facilitating cleaning of the interior of the bag body.

[0017] Furthermore, a bag cover is connected to the upper end of the rear bag body.

[0018] The upper end of the bag body is covered by the back cover, and the items in the bag body are placed to leak out from the top.

[0019] Furthermore, one end of the bag cover is connected to the upper end of the rear bag body, and the other end of the bag cover is connected to the front bag body through a snap.

[0020] The above arrangement facilitates fixing the bag cover to the front bag body through snaps to prevent items in the bag body from leaking out from above.

[0021] Furthermore, an accessory bag and one or more pen covers are arranged on the inner side of the bag cover; and a hanging strap is also arranged on the top of the bag cover.
