[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0031] Please refer to Figures 1 to 7 together. Now, a specific implementation manner of a multi - anti - theft backpack provided by the present utility model will be described. This multi - anti - theft backpack includes a main bag 1, shoulder straps 2, and a secondary bag 3, and also includes a two - way zipper 4, an anti - theft pull head 5, and a password lock 6. The two - way zipper 4 is arranged at the middle position of the top wall of the main bag 1. There are two anti - theft pull heads 5 for controlling the opening and closing of the two - way zipper 4. On the opposite ends of the two anti - theft pull heads 5, limit rings 51 are fixedly connected. The lock beam of the password lock 6 can penetrate through the two limit rings 51 in a coaxial state at the same time. On the side wall where the main bag 1 is connected to the shoulder strap 2, a first secondary bag 7 is provided, and a magic - tape bag cover or a first zipper 8 is provided on the first secondary bag 7.

[0032] For the convenience of description, please refer to Figure 1 together. Taking any point in space as the origin, with the setting direction of the password lock 6 relative to the main bag 1 as the Z - axis, the setting direction of the secondary bag 3 relative to the main bag 1 as the X - axis, and the direction of the straight line perpendicular to both the X - axis and the Z - axis as the Y - axis, a rectangular coordinate system is established. Among them, the XY plane is the horizontal plane, the direction indicated on the horizontal plane is the horizontal direction, and the direction indicated by the Z - axis is the vertical direction.

[0033] In this embodiment, the anti - theft pull head 5 is provided with a bayonet 52 adapted to the limit ring 51. The bayonet 52 is opened at the end of the top surface of the anti - theft pull head 5 and runs through the entire width of the anti - theft pull head 5. When the two relatively - arranged anti - theft pull heads 5 move to a state of abutment, the limit ring 51 on one anti - theft pull head 5 is engaged with the bayonet 52 on the other anti - theft pull head 5, and at the same time, the two limit rings 51 on the two anti - theft pull heads 5 are in a coaxial state. At this time, after passing the password lock 6 through the two limit rings 51 and locking it, the safety protection of the main bag 1 part is completed. The secondary bag 3 can be used to hold common items such as tissues, pens, and notebooks.

[0034] In a specific embodiment of the utility model, the main bag 1 is provided with a binding belt arranged perpendicularly to the shoulder strap 2, and the binding belt is detachable and wrapped around the waist and abdomen of the user, which can prevent the thief from snatching the entire backpack, and the use is safer. A second zipper 31 is provided on the side of the secondary bag 3. A covering strip for covering the second zipper 31 is also provided on the side of the secondary bag 3. The first secondary bag 7 can be used to hold commonly used documents, such as identity cards, driver's licenses, etc., for easy access.

[0035] In this embodiment, a cushion pad 13 is further provided on one side of the main bag 1 close to the shoulder strap 2. The cushion pad 13 includes a shoulder pad 131, a back pad 132 and a bottom pad 133. The shoulder pad 131 and the back pad 132 are symmetrically arranged on both sides of the first sub-bag 7, and the bottom pad 133 is arranged at the bottom of the first sub-bag 7. The shoulder pad 131 is arranged to surround the top of the shoulder strap 2. After the backpack is put on, the shoulder pad 131 is against the shoulder, the back pad 132 is in contact with the back, and the bottom pad 133 is in contact with the waist. The cushion pad 13 is made of a breathable, elastic and soft material, which can increase breathability and comfort.

[0036] In a specific embodiment of the present invention, the main bag 1 includes an outer bag body 14, a partition layer 15, a first cover 16 and a second cover 17, a two-way zipper 4 is arranged on the top of the outer bag body 14, and a receiving cavity is arranged in the outer bag body 14. The partition layer 15, the first cover 16 and the second cover 17 are all arranged in the receiving cavity, and the partition layer 15 divides the receiving cavity into a first cavity 141 and a second cavity 142. The first cover 16 and the second cover 17 are respectively arranged on both sides of the top of the partition layer 15, and are fixedly connected to the partition layer 15 and the outer bag body 14 at the same time.

[0037] In this embodiment, the first cover 16 is disposed between the second cover 17 and the secondary bag 3. Below the first cover 16 is a first bag cavity 141, and below the second cover 17 is a second bag cavity 142. Both the first bag cavity 141 and the second bag cavity 142 can contain required items as needed, such as clothing, power banks, computers, tablets, and other items.

[0038] In this embodiment, the second bag cavity 142 is provided with a second sub-bag 11 and a third sub-bag 12 arranged opposite to the second sub-bag 11. A fourth zipper is provided on the second sub-bag 11. Fourth sub-bags 19 are symmetrically provided on both sides of the outer bag 14. The second sub-bag 11 can contain small items such as change, and the third sub-bag 12 can contain contracts, secret materials, clothes, etc., which need to be stored separately and squeezed and supported.

[0039] In a specific embodiment of the present utility model, a third zipper 18 is provided on both the first cover 16 and the second cover 17. Alternatively, an opening and closing port and a drawstring for controlling the opening and closing of the opening and closing port are provided on both the first cover 16 and the second cover 17. Both the third zipper 18 and the drawstring are used to realize the opening and closing of the first cover 16 or the second cover 17. Herein, as long as the relevant performance functions of the above-mentioned third zipper 18 and drawstring can be realized, they are within the protection scope of this application document.

[0040] Compared with the prior art, through the cooperative setting of the password lock 6 and the limit ring 51, the main bag 1 is locked, completely eliminating the possibility of thieves opening the backpack to steal property, and the anti-theft effect is better. Through the setting of the first auxiliary bag 7, not only can important and commonly used items be taken at any time, but also the first auxiliary bag 7 is hidden. After the backpack is carried on the back, the first auxiliary bag 7 fits with the back, and thieves cannot steal important items from between the back and the main bag 1, improving the security of storing items in the backpack. Through the cooperative setting of the outer package 14, the first cover 16 and the second cover 17, a larger storage space can be obtained and more functional areas can be separated. After locking the anti-theft pull head 5 on the outer package 14, the theft of items in the first bag cavity 141 and the second bag cavity 142 can be directly prevented, and the backpack has more functions and higher security.

[0041] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the description of the method part.
