Description

Technical Field

[0001] This utility model relates to the field of backpack technology, and in particular to a backpack with an anti-theft protection structure. Background Technology

[0002] A backpack is a bag-shaped container made of fabric or flexible materials, equipped with shoulder straps for carrying on both shoulders or one shoulder. Its core function is to free up a person's hands by carrying and organizing items, and to achieve effective transfer of load. Through the division of the main compartment, compartments and functional pockets, it transforms scattered items into an orderly whole, allowing the wearer to safely and conveniently access what they need while on the move. Essentially, it is an extension of human function and a portable space solution that serves mobility and storage.

[0003] Existing backpacks still have some problems during use. For example, most backpacks currently use zippers or buckles for closure, which makes opening and closing the backpack convenient and smooth, and easy to use in daily life. However, since backpacks are usually carried on the back of the user, the user's back cannot be directly observed. Especially in crowded public places such as buses and subways, users cannot easily notice the status of the backpack, making backpacks easy targets for criminals in high-density crowds.

[0004] To address these issues, we provide a backpack with an anti-theft protection structure. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing technologies cannot effectively prevent theft of items inside backpacks. Therefore, we propose a backpack with an anti-theft protection structure.

[0006] To achieve the above objectives, this application adopts the following technical solution: a backpack with an anti-theft protection structure, comprising a backpack body, an audible and visual alarm fixedly connected to the bottom of one side of the backpack body, a control switch fixedly connected to the top of one side of the backpack body, a flip cover provided on one side of the top of the backpack body, a connecting plate fixedly connected to the bottom of the flip cover, an outer shell fixedly connected to the top of the other side of the backpack body, crossbars fixedly connected to both sides of the inner cavity of the outer shell, a sliding plate slidably connected to one side of the surface of the crossbar, a limit block fixedly connected to one side of the sliding plate, a spring sleeved on one side of the surface of the crossbar, and a mounting block fixedly connected to the bottom of the outer shell, with a contact sensor disposed inside the mounting block.

[0007] Preferably, a limiting groove is provided on one side of the connecting plate, and the limiting block is slidably connected inside the limiting groove.

[0008] Preferably, a through groove is provided on one side of the top of the outer casing, and the connecting plate is slidably connected inside the through groove.

[0009] Preferably, a back pad is fixedly connected to one side of the backpack body, and an anti-slip groove is provided on one side of the back pad.

[0010] Preferably, the mounting block has a mounting groove inside, and the contact sensor is fixedly connected inside the mounting groove.

[0011] Preferably, the limiting block is semi-circular in shape, and the limiting groove is semi-circular in shape.

[0012] The technical effects and advantages of this utility model are as follows: 1. This utility model, through the setting of crossbar, sliding plate, spring and limit block, can automatically lock the connecting plate when the flip cover is closed, preventing the flip cover from opening automatically due to external factors. At the same time, with the setting of contact sensor and sound and light alarm, it can immediately trigger a high-decibel alarm and flashing light when illegal opening behavior is detected, effectively deterring theft and immediately attracting the attention of users and people around, thereby greatly improving the anti-theft security of backpacks in public places.

[0013] 2. This utility model can conveniently deactivate or activate the anti-theft mode through the setting of the control switch, and can ensure the smoothness of the locking process and the stability after locking through the setting of the limit block and limit groove, while the setting of the back pad and anti-slip groove can enhance the comfort when carrying, thereby improving the convenience and comfort of the user.

[0020] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0021] Example 1 Please see Figures 1-5 This utility model is a backpack with an anti-theft protection structure, including a backpack body 1, an audible and visual alarm 2 fixedly connected to the bottom of one side of the backpack body 1, a control switch 3 fixedly connected to the top of one side of the backpack body 1, a flip cover 4 provided on one side of the top of the backpack body 1, a connecting plate 5 fixedly connected to the bottom of the flip cover 4, an outer shell 6 fixedly connected to the top of the other side of the backpack body 1, crossbars 7 fixedly connected to both sides of the inner cavity of the outer shell 6, a sliding plate 8 slidably connected to one side of the surface of the crossbar 7, a limit block 9 fixedly connected to one side of the sliding plate 8, a spring 10 sleeved on one side of the surface of the crossbar 7, and a mounting block 11 fixedly connected to one side of the bottom of the outer shell 6, with a contact sensor 12 installed inside the mounting block 11.

[0022] Specifically: the sound and light alarm 2, the control switch 3, and the contact sensor 12 are all existing technologies, so they will not be described in detail here. The flip cover 4 can seal the backpack body 1 to prevent external dust or water from affecting the items inside. There are two crossbars 7, which are fixed in the inner cavity of the outer shell 6. The spring 10 is sleeved on one side of the surface of the crossbar 7, and its two ends are fixedly connected to one side of the slide plate 8 and one side of the inner wall of the outer shell 6, respectively. It can move the limiting block 9 into the limiting groove 13 through its own elasticity.

[0023] Example 2 Please see Figures 1-5 Based on embodiment 1, a limiting groove 13 is provided on one side of the connecting plate 5, and the limiting block 9 is slidably connected to the inside of the limiting groove 13. A through groove 14 is provided on one side of the top of the outer shell 6, and the connecting plate 5 is slidably connected to the inside of the through groove 14. A back pad 15 is fixedly connected to one side of the backpack body 1, and an anti-slip groove 16 is provided on one side of the back pad 15. An installation groove 17 is provided inside the mounting block 11, and a contact sensor 12 is fixedly connected to the inside of the installation groove 17. The limiting block 9 is semi-circular in shape, and the limiting groove 13 is semi-circular in shape.

[0024] Specifically: the limiting groove 13 can assist the limiting block 9 in limiting the flap 4 and the connecting plate 5, thereby preventing the flap 4 from releasing the seal on the backpack body 1 due to external vibration and other factors; the through groove 14 can facilitate the insertion of the connecting plate 5 into the shell 6; the back pad 15 can increase the user's comfort during use; and the mounting groove 17 can provide installation space for the contact sensor 12.

[0025] Working principle: When the user closes the flip cover 4, the user inserts the connecting plate 5 into the housing 6 through the through slot 14. When the connecting plate 5 contacts the limiting block 9, the connecting plate 5 will push the sliding plate 8 to move through the limiting block 9. When the sliding plate 8 moves, it will squeeze the spring 10. When the limiting block 9 is flush with the limiting groove 13, the spring 10 will push the sliding plate 8 and the limiting block 9 into the limiting groove 13 through its own elasticity, thereby locking the flip cover 4. Then the user activates the contact sensor 12 through the control switch 3.

[0026] If the flip cover 4 is forcibly opened without authorization, the displacement of the connecting plate 5 will trigger the contact sensor 12 inside the mounting block 11. The sensor will immediately transmit a signal to the audible and visual alarm 2, causing it to activate a high-decibel alarm and flashing lights to deter theft and alert the user and those around them. When the user needs to open the flip cover 4, the user only needs to turn off the contact sensor 12 via the control switch 3 and then open it. This ensures convenience for daily use while effectively improving the anti-theft performance of the backpack in crowded environments.

[0027] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
