[0021] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0022] This application discloses a backpack with a detachable movable buckle. (Refer to...) Figures 1 to 5 A backpack with detachable movable buckles includes a male buckle 1 and a female buckle 2. A nipple pin 11 is fixedly connected to one side of the male buckle 1, and an installation groove 21 is opened on one side of the female buckle 2. A support plate 22 is fixedly connected to the inner wall of the installation groove 21, and an arc-shaped protrusion 23 is provided on the inner wall of the support plate 22. The surface of the nipple pin 11 is slidably connected to the inner wall of the installation groove 21 and the support plate 22. An anti-detachment component 3 is provided on the inner wall of the installation groove 21. The backpack with detachable movable buckles is composed of the male buckle 1 and the female buckle 2. The nipple pin 11 on one side of the male buckle 1 is inserted into the installation groove 21 of the female buckle 2. Pushing the male buckle 1 or the female buckle 2 causes the connecting rod of the nipple pin 11 to be engaged with the inner wall of the support plate 22. The arc-shaped protrusion 23 can limit the connecting rod of the nipple pin 11, thereby improving the convenience of buckle assembly and disassembly, and also improving the convenience of backpack strap replacement.
[0023] After the male buckle 1 and female buckle 2 are connected, the dynamic angle between them and the shoulder strap can be automatically adjusted (0-180°) to adapt to different shoulder widths and body characteristics. For example, users with broad shoulders can adjust the buckle tilt angle automatically to make the backpack's center of gravity close to the back curve and reduce shoulder and neck pressure.
[0024] The male buckle 1 and female buckle 2 adopt an adjustable angle combination structure to fit the natural curvature of the shoulder. Through multi-point force distribution design, the weight of the backpack is evenly distributed to the shoulder, back and waist, avoiding shoulder deformation or uneven shoulder problems caused by excessive local pressure.
[0025] Reference Figure 2 and Figure 3 The male buckle 1 has a first through groove 12 on one side, and the female buckle 2 has a second through groove 24 on one side. The inner wall of the second through groove 24 is connected to the inner wall of the mounting groove 21. The first through groove 12 and the second through groove 24 facilitate the backpack straps to pass through and connect.
[0026] Reference Figure 1 , Figure 3 and Figure 5The anti-detachment component 3 includes a mounting block 31. One side of the mounting block 31 is attached to the inner wall of the mounting groove 21. A first fastening plate 32 is fixedly connected to one side of the mounting block 31. The inner wall of the first fastening plate 32 is attached to the surface of the nipple nail 11. One side of the first fastening plate 32 is attached to one side of the support plate 22. Through the anti-detachment component 3, the anti-detachment component 3 abuts between the male buckle 1 and the female buckle 2, so as to avoid the male buckle 1 and the female buckle 2 from separating due to accidental pulling. The mounting block 31 in the anti-detachment component 3 mainly plays the role of connection and support. The first fastening plate 32 is integrally formed with the mounting block 31. The first fastening plate 32 can abut the end of the nipple nail 11, so as to ensure that the male buckle 1 rotates while avoiding the male buckle 1 and the female buckle 2 from separating.
[0027] Reference Figure 3 and Figure 4 A reinforcing block 33 is fixedly connected to one side of the mounting block 31, and a slot 25 is provided on one side of the female buckle 2. The surface of the reinforcing block 33 is inserted into the inner wall of the slot 25. With the reinforcement block 33, the mounting block 31 is inserted into the mounting groove 21, and the reinforcement block 33 is connected to the slot 25. The cooperation between the reinforcement block 33 and the slot 25 further improves the firmness of the anti-detachment component 3.
[0028] Reference Figure 4 and Figure 5 An elastic plate 34 is slidably connected to the inner cavity of the mounting block 31. One side of the elastic plate 34 is fixedly connected to the second fastening plate 35. The inner wall of the second fastening plate 35 is in contact with the surface of the nipple nail 11. Through the elastic plate 34, the elastic plate 34 and the second fastening plate 35 are integrally formed. The elastic plate 34 can be elastically supported by elastic elements such as springs, so that the second fastening plate 35 abuts against the connecting rod of the nipple nail 11, further improving the firmness of the anti-detachment component 3.
[0029] Reference Figure 4 and Figure 5 The inner cavity of the mounting block 31 is slidably connected to an elastic frame 36, and the inner cavity of the elastic frame 36 is rotatably connected to a guide roller 37. Through the set elastic frame 36, the elastic frame 36 can ensure elastic support through elastic elements such as springs, so that the guide roller 37 fits against the back strap in the second through groove 24, ensuring the back strap can be pulled and adjusted while increasing the firmness of the connection between the back strap and the buckle 2.
[0030] Working principle: The buckle is composed of male buckle 1 and female buckle 2. The nipple pin 11 on one side of male buckle 1 is inserted into the mounting groove 21 of female buckle 2. Pushing male buckle 1 or female buckle 2 causes the connecting rod of nipple pin 11 to engage with the inner wall of support plate 22. The arc-shaped protrusion 23 can limit the connecting rod of nipple pin 11, thereby improving the convenience of buckle assembly and disassembly, and also improving the convenience of backpack strap replacement. After male buckle 1 and female buckle 2 are connected, the dynamic angle between them and the backpack strap can be automatically adjusted (0-180°). The backpack is designed to accommodate different shoulder widths and body types. For example, users with wider shoulders can automatically adjust the buckle angle to align the backpack's center of gravity with the back curve, reducing pressure on the shoulders and neck. The male buckle 1 and female buckle 2 feature a movable angle combination structure that conforms to the natural curvature of the shoulder. Through a multi-point force distribution design, the backpack's weight is evenly distributed to the shoulders, back, and waist, preventing shoulder deformation or uneven shoulders caused by excessive localized pressure. The first through-slot 12 and the second through-slot 24 facilitate the connection of the backpack straps. The anti-slip component 3 abuts against... To prevent the male buckle 1 and female buckle 2 from detaching due to accidental pulling, the mounting block 31 in the anti-detachment component 3 mainly serves as a connecting support. The first fastening plate 32 is integrally formed with the mounting block 31. The first fastening plate 32 can abut against the end of the nipple nail 11, ensuring that the male buckle 1 rotates while preventing the male buckle 1 and female buckle 2 from detaching. The mounting block 31 is inserted into the mounting groove 21, while the reinforcing block 33 is connected to the slot 25. The cooperation between the reinforcing block 33 and the slot 25 further improves the firmness of the anti-detachment component 3. The elastic plate 34 is integrally formed with the second fastening plate 35. The elastic plate 34 can be elastically supported by springs and other elastic elements, so that the second fastening plate 35 abuts against the connecting rod of the nipple nail 11, further improving the firmness of the anti-detachment component 3. The elastic frame 36 can be elastically supported by springs and other elastic elements, so that the guide roller 37 fits against the strap in the second through groove 24, ensuring the strap can be pulled and adjusted while increasing the firmness of the connection between the strap and the female buckle 2.
