[0032] Specifically, the D-ring buckle 3 and the fixing strap 4 work together. Users adjust the length by sliding the fixing strap 4 through the hole in the D-ring buckle 3 to accommodate different heights and habits. The pin 5 engages with the hole in the backpack 1 to quickly fix and remove the fixing strap 4 and adjust the shoulder strap connection. The ratchet 8 and pawl 9 form an adjustable angle structure. Spring 10 keeps the pawl 9 engaged with the ratchet 8. When adjusting the angle of the fixing bracket 7, the spring force of spring 10 is overcome, the pawl 9 disengages from the ratchet 8, rotates, and then re-engages, fixing the tilt angle of the shoulder strap 12 to meet different carrying needs. The fixing shoulder strap 12 connects to the fixing box 13. The fixing block 14 pops out and retracts under the action of spring 15. When connecting, spring 15 pushes the fixing block 14 into the slot for a secure connection. Disassembly When the fixing block 14 is pressed, it overcomes the elastic force of the spring 15, separating the fixing shoulder strap 12 for easy change and combination. The support mechanism 2 is fixed to the back of the outer wall of the backpack 1. Through its own structure, it fits the waist to provide support for the waist, distribute the weight of the backpack 1, reduce the pressure on the waist, and improve the comfort and stability when carrying it. The magnet 16 on the outer wall of the fixing box 13 uses magnetic properties to be attracted and connected with other magnetic components, which facilitates quick fixing or disassembly of related accessories and enhances the functionality and flexibility of the backpack 1. The pad 27 on the back of the top of the backpack 1 can increase the softness and wear resistance of the top of the backpack 1. When placing items or stacking the backpack 1, it plays a cushioning and protective role to avoid damage to the items and extend the service life of the top of the backpack 1.

[0033] Reference Figure 1 , Figure 2 and Figure 5The support mechanism 2 includes a fixing strip 201, which is fixedly connected to the rear side of the outer wall of the backpack 1. A telescopic frame 202 is rotatably connected to the side of the outer wall of the fixing strip 201 away from the wall. A spring plate 203 is rotatably connected to the adjacent side of the inner wall of the fixing strip 201. A spring tube 204 is fixedly connected to the bottom of the outer wall of the spring plate 203. An adjustment frame 205 is fixedly connected to the bottom of the outer wall of the spring tube 204. An adjustment plate 206 is fixedly connected to the top of the outer wall of the adjustment frame 205.

A connecting rod 18 is fixedly connected to the four sides of the outer wall of the waist support 207. A shoulder pad 19 is slidably connected to one side of the outer wall of the fixed shoulder strap 12. A lifting device 20 is fixedly connected to the top of the outer wall of the backpack 1.

[0034] Specifically, the support mechanism 2 provides comfortable lumbar support through component cooperation. The fixing bar 201 serves as the basic support, the telescopic frame 202 is adjustable to fit the lumbar curve and allows movement, the spring plate 203 and spring tube 204 form an elastic cushioning structure to distribute the pressure of the backpack 1 and reduce the burden on the lumbar region, the adjustment frame 205 and adjustment plate 206 allow the user to adjust the support strength and fit, the lumbar support 207 directly contacts the lumbar region, providing stable support, improving comfort, and reducing fatigue, and the spring 3 17 is connected to the top front of the lumbar support 207. When the user carries the backpack 1, the spring 3 17 uses its own elastic deformation to absorb the lumbar pressure. The lumbar support 207 distributes the weight of the backpack 1 to reduce pressure on the waist, and the connecting rods 18 around the waist support 207 provide stable support, maintain the shape and position of the waist support 207, and make it better fit the waist curve to enhance the support for the waist. The shoulder pads 19 on the fixed shoulder straps 12 are adjustable and can be adjusted according to the user's shoulder shape and shoulder width to increase the contact area between the shoulder and the shoulder strap, and avoid the shoulder from marks and pain caused by long-term stress. The lifting handle 20 at the top of the backpack 1 makes it easy for the user to lift the backpack 1 with one hand, providing a convenient point of leverage whether moving the backpack 1 a short distance or taking the backpack 1 from a high place.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A sealing strip 21 is fixedly connected to the top front side of backpack 1, a storage pocket 22 is fixedly connected to the bottom right side of backpack 1, a connecting strap 23 is fixedly connected to the left and right sides of the outer wall of backpack 1, a hanging ring 24 is rotatably connected to the middle of the inner wall of the connecting strap 23, a storage bag 25 is fixedly connected to the front side of the outer wall of backpack 1, and a vent 26 is installed on one side of the outer wall of the storage bag 25.

[0036] Specifically, the sealing strip 21 forms a sealed protective layer on the top front of the backpack 1 by tightly fitting together, which can effectively prevent rainwater and dust from entering the backpack 1 and protect the stored items; the storage pocket 22 is located on the bottom right side of the backpack 1, providing additional open storage space for users to quickly access frequently used small items; the connecting strap 23 is fixed to the outer wall of the backpack 1, and the hanging ring 24 connected to its inner wall can rotate freely in all directions, allowing users to hang items such as water bottles and keychains, which are flexible to access and do not affect the carrying of the backpack 1; the storage bag 25 is used to store more items, and the vent 26 on the outer wall can expel excess air when the items inside the bag are compressed, reducing the volume of the storage bag 25, making it easier to store and organize, and also preventing the bag from expanding and deforming due to changes in air pressure.

[0037] Working principle: The D-ring buckle 3 engages with the fixing strap 4, allowing the user to slide the fixing strap 4 through different holes in the D-ring buckle 3, flexibly adjusting the length of the fixing strap 4 to suit different heights and usage habits; the pin 5 engages with the corresponding pin holes of the backpack 1 and other components, allowing for quick fixing or removal of the fixing strap 4, thus adjusting the shoulder strap connection method; the ratchet 8 and pawl 9 form an adjustable angle connection structure; the spring 10 keeps the pawl 9 engaged with the ratchet 8; when it is necessary to adjust the angle between the fixing bracket 2 7 and the fixing bracket 6, external force is applied to overcome the elasticity of the spring 10, causing the pawl 9 to disengage from the ratchet 8 and rotate the fixing bracket 2 6. After the frame 7 is adjusted to the appropriate angle, the pawl 9, under the action of the spring 10, re-engages into the tooth groove of the ratchet 8, thus fixing the tilt angle of the fixed shoulder strap 12 to meet the needs of different carrying postures. One end of the fixed shoulder strap 12 is connected to the fixing box 13. The fixing block 14 can pop out or retract within the fixing box 13 due to the elastic force of the spring 15. When the fixed shoulder strap 12 is connected to other components, the spring 15 pushes the fixing block 14 into the corresponding slot to achieve a firm connection. When disassembling, pressing the fixing block 14 overcomes the elastic force of the spring 15 to separate the fixed shoulder strap 12, facilitating the change and combination of the shoulder strap.

[0038] The support mechanism 2, through the cooperation of its various components, provides comfortable support for the wearer's lower back. The fixing bar 201 is fixed to the back of the backpack 1, serving as the basic support component of the entire mechanism. The telescopic frame 202 is rotatably connected to the fixing bar 201, allowing for opening and closing adjustments according to the wearer's body shape or movements. While conforming to the waist curve, it allows for a certain range of movement, avoiding restriction of waist movement due to structural fixation. The spring plate 203 and spring tube 204 constitute an elastic cushioning structure. When the backpack 1 is subjected to force, the spring plate 203 can rotate around the fixing bar 201, while simultaneously springing back. The spring tube 204 undergoes elastic deformation, absorbing and dispersing the pressure from the backpack 1, reducing the burden on the waist. The adjustment frame 205 and adjustment plate 206 allow users to adjust the position and angle of the spring plate 203 and spring tube 204 according to their own needs, optimizing the support and fit. The lumbar support 207 is fixed to the right side of the spring plate 203 and directly contacts the waist. Under the buffering effect of the spring plate 203 and spring tube 204, it always fits the waist, providing stable support for the waist, improving carrying comfort, and reducing fatigue caused by carrying for a long time.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
