DETAILED DESCRIPTION

[0022] It should be noted that the embodiments and features in the embodiments in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0023] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0024] In the present application, unless otherwise specified, the directions used such as "up, down" are generally with respect to the directions shown in the drawings, or with respect to the vertical, perpendicular or gravitational direction. Similarly, for the convenience of understanding and description, "left, right" is generally with respect to the left and right shown in the drawings; "inner, outer" refers to the inner and outer with respect to the contour of each component itself, but the above directional words are not used to limit the present application.

[0025] Please refer to Figures 1-6 The present application provides a technical scheme: a self-adaptive knob adjusting back bag, comprising a backpack body 1, both sides of the backpack body 1 are provided with adjustable shoulder straps 2, and the back side of the backpack body 1 is provided with a protective layer 3.

[0026] The inside of the protective layer 3 is provided with a carbon fiber support group 4, specifically, the back side of the backpack body 1 is embedded and fixedly provided with a guide groove 10, the inside of the guide groove 10 is slidably installed with a connecting block 11, the connecting block 11 is fixedly connected with an elastic plate 8, the inside of the guide groove 10 is rotatably installed with a screw 12, the screw 12 is threadedly connected with the connecting block 11, the bottom end of the screw 12 extends to the lower side of the guide groove 10, and the bottom end of the screw 12 is fixedly connected with a knob 13. By rotating the knob 13, the knob 13 drives the screw 12 to rotate, the screw 12 rotates and threadedly cooperates with the connecting block 11, so that the connecting block 11 moves up and down in the inside of the guide groove 10, thereby driving the elastic plate 8 to move up and down in the inside of the protective layer 3, and thereby adjusting the position of the carbon fiber support group 4. The user can accurately adjust the position of the carbon fiber support group 4 to adapt to different body types and carrying needs.

[0027] The protective layer 3 has an elastic cushioning layer 5 on the side opposite to the backpack body 1. The elastic cushioning layer 5 has a built-in honeycomb air cushion that dynamically adjusts its deformation according to the pressure on the back, reducing local pressure. The honeycomb structure design increases air circulation and reduces the feeling of stuffiness on the back.

[0028] like Figure 2 As shown, an elastic support piece 6 is fixed to the rear side of the backpack body 1. A sponge sleeve covers the outer side of the elastic support piece 6. A knob tightening assembly 7 is located on the rear side of the backpack body 1. The knob tightening assembly 7 includes a tightening rope 17 and an adjustment knob 18. The tightening rope 17 is wound inside the adjustment knob 18. An insertion channel is provided on the inner edge of the sponge sleeve, through which the tightening rope 17 passes. The elastic support piece 6 cooperates with the knob tightening assembly 7. The knob tightening assembly 7 is prior art as described in Chinese invention patent number 201810374864.8. Here, we are only using it without making any structural or functional improvements, and we will not elaborate further. Rotating the adjustment knob 18 can wind up the tightening rope 17, causing the elastic support piece 6 to bend, making it fit the user's back better and reducing the burden on the spine.

[0029] The carbon fiber support assembly 4 includes an elastic plate 8 and arc-shaped support plates 9. The elastic plate 8 is slidably positioned inside the protective partition 3. Multiple arc-shaped support plates 9 are evenly arranged on the elastic plate 8 from top to bottom, with both ends of the arc-shaped support plates 9 slidably connected to the elastic plate 8. Specifically, rectangular grooves 14 are formed on both sides of the elastic plate 8 corresponding to the positions of the arc-shaped support plates 9. Slider blocks 15 are slidably installed inside the rectangular grooves 14, and the sliders 15 are fixedly connected to the ends of the corresponding arc-shaped support plates 9. Springs 16 are fixedly connected inside the rectangular grooves 14, and the other end of the springs 16 is fixedly connected to the sliders 15. The evenly arranged multiple arc-shaped support plates 9 provide segmented and precise support, conforming to the natural curvature of the spine. The elasticity of the springs 16 further absorbs impact force, reduces vibration impact on the spine, and improves carrying comfort.

[0030] Working principle:

[0031] In use, the user first firmly puts the backpack on his back through the adjustable straps on both sides. Then, by manually rotating the knob 13, the internal screw rod 12 is driven to rotate. The screw rod 12 and the connecting block 11 are in threaded connection, so that the connecting block 11 moves up and down steadily under the constraint of the guide groove 10 as the screw rod 12 continuously rotates. The up and down movement further drives the elastic plate 8 to adjust up and down in the internal protection layer 3, thereby realizing the accurate control of the position of the carbon fiber support group 4. The user can adjust the carbon fiber support group 4 to the most appropriate position according to his height and the length of the spine. At this time, the arc-shaped support plate 9 naturally fits the middle part of the user's spine when the backpack is carried. Next, by rotating the adjusting knob 18, the tightening rope 17 is gradually pulled into the knob, thereby adjusting the bending degree of the elastic support piece, so that the backpack body is closer to the user's spine. The arc-shaped support plate 9 has the performance of deformation and rebound, and can automatically adjust the bending arc according to the physiological curve of the user's lumbar vertebrae, so as to ensure the comfort and support effect in the carrying process.

[0032] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by the ordinary skilled in the art without departing from the purpose of the utility model.
