[0002] When carrying out special missions, domestic public security officers, armed police, auxiliary police, and other personnel have to wear bulletproof vests, carry shields, and tactical backpacks, which makes their movements extremely inconvenient and can easily affect the effectiveness of the mission.
[0003] Currently, existing technology CN217658600U discloses a bulletproof backpack, including: a backpack body, a first protective belt, a second protective belt, and a shield; wherein, the first and second protective belts are respectively provided on both sides of the backpack body, and the inner side of the first protective belt and the outer side of the second protective belt are provided with Velcro for adhesive fixation; the shield is detachably provided on the second protective belt, and the ends of the first and second protective belts away from the backpack body are provided with drawstrings; the first and second protective belts can be unfolded and wrapped around and fixed at the waist; a bulletproof layer is provided on the inner side of the backpack body. This application achieves the technical effect of improving the flexibility of use and integrating bulletproof vest, backpack, and shield into one unit, providing all-round protection, thereby solving the problem that the bulletproof backpacks in related technologies have relatively single functions and are difficult to provide comprehensive protection in the event of an emergency.
[0004] However, the shields are fixed by Velcro fasteners on the second protective belt. The adhesive strength of the Velcro is greatly affected by factors such as the number of times it is used, the ambient humidity, and the angle of force. In the event of a sudden conflict or violent movement, if the shields are torn or impacted by external forces, there is a risk that the shields may fall off, affecting the protective effect. Utility Model Content
[0005] The purpose of this invention is to provide a detachable bulletproof backpack, which aims to solve the problem that the shield of existing bulletproof backpacks is subject to the influence of the strength of the Velcro, and there is a risk that the shield will fall off after long-term use.
[0006] To achieve the above objectives, this utility model provides a detachable bulletproof backpack, including a bulletproof backpack body, a protective strap, a shield, and a connecting assembly. The protective strap is disposed on one side of the bulletproof backpack body. The connecting assembly includes a connecting base plate, a snap-fit block, and a fixing buckle. The connecting base plate is fixed to one side of the protective strap and has a snap-fit groove located on one side of the connecting base plate. The snap-fit block is fixedly connected to the shield and detachably connected to the connecting base plate, and is located on the side of the shield near the connecting base plate. The fixing buckle is assembled on the top of the connecting base plate.
[0007] The connecting component further includes a suction cup, which is fixedly connected to the connecting base plate and located within the snap-fit groove.
[0008] The snap-fit block includes a snap-fit block body and a docking rod. The snap-fit block body is fixedly connected to the shield and detachably connected to the base plate, and is located on the side of the shield near the base plate. The docking rod is fixedly connected to the snap-fit block body and is located on the top of the snap-fit block body.
[0009] The fixing buckle includes a rotating head and a lever. The rotating head is rotatably mounted on the connecting base plate near the docking rod. The rotating head has a slot located on one side of the rotating head. The lever is fixedly connected to the rotating head and is located on one side of the rotating head.
[0010] The detachable bulletproof backpack also includes a soft magnetic sheet, which is fixedly connected to the connecting base plate and located on the side of the connecting base plate near the paddle.
[0011] This utility model discloses a detachable bulletproof backpack. The protective strap is secured to both sides of the backpack body with connecting buckles. The connecting component is used to install the shield on the protective strap. During shield installation, the user uses their hand to pull and rotate the fixing buckle, then picks up the shield, aligns the locking block with the locking groove on the connecting base plate, and inserts the connecting block into the locking groove to achieve initial shield installation. Finally, the user rotates in the opposite direction and presses down the fixing buckle, which blocks the connection between the connecting base plate and the top of the locking block, reinforcing the connection between the connecting base plate and the locking block, thus completing the shield installation. The connecting component initially secures the shield through the locking of the connecting base plate and the locking block, and further reinforces it with the fixing buckle. Compared to traditional Velcro fastening, the shield connection is more stable and consistent, thus solving the problem that the existing bulletproof backpack shield adhesive strength is affected by the Velcro strength, leading to the risk of the shield falling off after prolonged use.

Detailed Implementation
[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0019] Please see Figures 1 to 4 This utility model provides a detachable bulletproof backpack, including a bulletproof backpack 1, a protective belt 2, a shield 3, and a connecting component 4. The protective belt 2 is disposed on one side of the bulletproof backpack 1. The connecting component 4 includes a connecting base plate 41, a snap-fit block 42, and a fixing buckle 43. The connecting base plate 41 is fixed to one side of the protective belt 2. The connecting base plate 41 has a snap-fit groove 44 located on one side of the connecting base plate 41. The snap-fit block 42 is fixedly connected to the shield 3 and detachably connected to the connecting base plate 41, and is located on the side of the shield 3 near the connecting base plate 41. The fixing buckle 43 is assembled on the top of the connecting base plate 41.
[0020] In this embodiment, the protective strap 2 is secured to both sides of the bulletproof backpack 1 via a connecting buckle. The connecting assembly 4 is used to mount the shield 3 onto the protective strap 2. When installing the shield 3, the user uses their hand to pull and rotate the fixing buckle 43, then picks up the shield 3, aligns the locking block 42 with the locking groove 44 of the connecting base plate 41, and inserts the locking block 42 into the locking groove 44 to achieve initial installation of the shield 3. Finally, the user rotates in the opposite direction and presses down the fixing buckle 43 to block the shield. The connection point between the top of the connecting base plate 41 and the snap-fit block 42 reinforces the connection between the connecting base plate 41 and the snap-fit block 42, thus completing the installation of the shield 3. The connecting component 4 initially fixes the shield 3 by snapping together the connecting base plate 41 and the snap-fit block 42, and further reinforces it by the fixing buckle 43. Compared with traditional Velcro fastening, the connection effect of the shield 3 is more stable and consistent, thereby solving the problem that the adhesive strength of the shield 3 in the existing bulletproof backpack 1 is affected by the strength of the Velcro, and there is a risk that the shield 3 will fall off after long-term use.
[0021] Furthermore, the connecting component 4 also includes a suction cup 45, which is fixedly connected to the connecting base plate 41 and located within the snap-fit groove 44.
[0022] In this embodiment, the suction cup 45 is provided to hold the snap-fit block 42 inserted into the connecting base plate 41, thereby further enhancing the connection between the connecting base plate 41 and the snap-fit block 42.
[0023] Furthermore, the snap-fit block 42 includes a snap-fit block body 421 and a docking rod 422. The snap-fit block body 421 is fixedly connected to the shield 3 and detachably connected to the connecting base plate 41, and is located on the side of the shield 3 near the connecting base plate 41. The docking rod 422 is fixedly connected to the snap-fit block body 421 and is located on the top of the snap-fit block body 421.
[0024] In this embodiment, after the snap-fit block body 421 is inserted into the bottom of the snap-fit groove 44, it is fixed by suction cup 45. At this time, the docking rod 422 on the top of the snap-fit block body 421 and the docking point of the connecting base plate 41 are docked, completing the snap-fit (initial installation) of the connecting base plate 41 and the snap-fit block 42.
[0025] Furthermore, the fixing buckle 43 includes a rotating head 431 and a lever 432. The rotating head 431 is rotatably disposed on the side of the connecting base plate 41 near the docking rod 422. The rotating head 431 has a slot 433 located on one side of the rotating head 431. The lever 432 is fixedly connected to the rotating head 431 and is located on one side of the rotating head 431.
[0026] In this embodiment, after the docking rod 422 on the top of the snap-fit block body 421 and the docking point of the connecting base plate 41 are docked, the user uses his hand to push the lever 432, rotates the rotating head 431 in the opposite direction, and presses the lever 432 so that the lever 432 is parallel to the connecting base plate 41 (during the rotation of the rotating head 431, under the action of the slot 433, the rotating head 431 rotates around the snap-fit rod). At this time, the rotating head 431 blocks the docking point of the connecting base plate 41 and the docking rod 422, strengthening the connection effect between the connecting base plate 41 and the snap-fit block 42, thus completing the installation of the shield 3.
[0027] Furthermore, the detachable bulletproof backpack 1 also includes a soft magnetic sheet 46, which is fixedly connected to the connecting base plate 41 and located on the side of the connecting base plate 41 near the paddle 432.
[0028] In this embodiment, the soft magnetic sheet 46 is provided to attract and fix the paddle 432, so as to prevent the paddle 432 from rotating due to the impact of the connecting base plate 41 when there is a conflict or tear, thereby causing the rotating clamp 431 to rotate, affecting the connection effect between the connecting base plate 41 and the docking rod 422, and ultimately affecting the fixing effect of the shield 3.
[0029] The above-disclosed embodiment of a detachable bulletproof backpack is merely a preferred embodiment of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments, and equivalent variations made in accordance with the claims of this application, still fall within the scope of this application.
