[0033] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this embodiment provides an adjustable backpack, including a bag body 10 and a back panel 20. The back panel 20 is provided with a shoulder strap 201, a webbing 202 fitted inside the shoulder strap 201, and an adjustment knob 203 that drives the webbing 202 to move back and forth. The shoulder strap 201 can be a double shoulder strap 201 structure. A channel is provided inside the shoulder strap 201 so that the webbing 202 is fitted inside the channel and can be moved inside the channel by pulling the webbing 202. An adjustment knob 203 is located in the middle of the back panel 20, and the end of the webbing 202 is located on the bag body 10. A first adjustment rope 204 is provided between the adjustment knob 203 and one end of the webbing 202 to drive the webbing 202 to move in a first direction. A second adjustment rope 205 is provided between the adjustment knob 203 and the other end of the webbing 202 to drive the webbing 202 to move in the opposite direction. The first adjustment rope 204 and the second adjustment rope 205 can be steel wire ropes or nylon ropes. The adjustment knob 203 rotates to drive the first adjustment rope 204 and the second adjustment rope 205, thereby realizing the movement of the webbing 202.

[0034] Specifically, the bag body 10 and the back panel 20 are designed as separate units. Shoulder straps 201 are designed on the back panel 20 for carrying. The back panel 20 and the bag body 10 are connected by webbing 202. The tightness of the webbing 202 is adjusted via a knob 203, allowing users to adjust the carrying comfort according to their needs. In use, rotating the adjustment knob 203: if rotated clockwise, the first adjustment cord 204 tightens, moving the webbing 202 in the first direction. This tightens the webbing 202 at the top of the backpack, causing the back panel 20 to move towards the bag body 10, making it fit snugly against the back. Similarly, rotating counterclockwise tightens the second adjustment cord 205, moving the webbing 202 in the opposite direction. This tightens the lower end of the webbing 202, causing the back panel 20 to move downwards, ensuring the backpack fits snugly against the back and improving carrying stability.

[0035] Furthermore, the adjustment knob 203 can be a self-locking mechanical knob, which utilizes a threaded structure to achieve a self-locking function, securely winding the adjustment cord around the adjustment knob 203 to prevent the webbing 202 from accidentally loosening during carrying, ensuring that the adjusted webbing 202 remains stable and improving the user experience. Specifically, the adjustment knob 203 can be a commercially available conventional strapless rotary button, or the knob-and-buckle strap structure disclosed in patent ZL2018104810913.

[0036] like Figure 1As shown, in this embodiment, the distance between the two ends of the webbing 202 is less than the distance between the two ends of the shoulder straps 201, or the distance between the two ends of the webbing 202 is greater than the distance between the two ends of the shoulder straps 201. Thus, when one end of the webbing 202 is pulled to bring the back panel 20 into contact with the bag body 10, the back panel 20 will move towards the pulled end. For example, when the first adjusting rope 204 is adjusted and rotated to tighten the top of the webbing 202, the back panel 20 moves upward (the bag body 10 moves downward). This change in the distance between the two ends of the webbing 202 allows the user to adjust the position of the back panel 20 according to their carrying habits, ensuring that the backpack maintains an optimal fit under different loads, reducing back pressure, and improving comfort during long-term carrying. Conversely, when rotated in the opposite direction, the second adjusting rope 205 pulls the lower end of the webbing 202 to tighten, causing the back panel 20 to move downward (the bag body 10 moves upward), achieving a close fit between the back and the backpack.

[0037] Furthermore, such as Figure 2 and Figure 3 As shown, in this embodiment, a first protrusion structure 206 is provided on the top of the back of the package 10 to abut against the top of the back panel 20, and / or a second protrusion structure 207 is provided on the bottom of the back of the package 10 to abut against the bottom of the back panel 20.

[0038] Specifically, the first protrusion structure 206 and the second protrusion structure 207 can be arc-shaped protrusions, designed at the top and bottom of the back of the bag body 10. Thus, when the top of the back panel 20 is pulled closer together by the webbing 202, the top of the back panel 20 is supported by the arc-shaped protrusions, causing the top of the back panel 20 to bend and conform to the human back. Similarly, when the bottom of the back panel 20 is pulled closer together by the webbing 202, the bottom arc-shaped protrusions support the back panel 20, causing it to bend and conform to the back, enhancing support, distributing weight, and improving carrying comfort.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, at least one first bending groove 208 is provided between the end position of the top fixed shoulder strap 201 of the back panel 20 and the adjustment knob 203; at least one second bending groove 209 is provided between the end position of the bottom fixed shoulder strap 201 of the back panel 20 and the adjustment knob 203.

[0040] Specifically, the bending groove is a strip-shaped inner groove. For example, three bending grooves can be designed side by side so that the bottom or top of the back panel 20 can be bent and fitted. The concave design of the bending groove increases the flexibility of the back panel 20, enabling it to achieve the desired bending and fitting.

[0041] In this embodiment, a receiving groove 210 for mounting the adjustment knob 203 is provided in the middle of the back panel 20. The design of the receiving groove 210 can accommodate the adjustment knob 203, avoiding the knob from being exposed and forming protrusions, which would affect carrying comfort. At the same time, the receiving groove 210 can be protected by adjusting its depth and width, preventing the knob from being accidentally impacted during carrying and extending its service life.

[0042] like Figure 5 and Figure 6 As shown, in this embodiment, an operating distance is provided between the adjustment knob 203 and the receiving groove 210 for manual operation, with the top surface of the adjustment knob 203 located within the groove of the receiving groove 210. This operating distance design facilitates user operation, ensuring a moderate distance between the adjustment knob 203 and the receiving groove 210, allowing for easy adjustment of the knob 203. Simultaneously, it also ensures that the softer parts of the back panel 20 contact the human body, improving the fit and comfort when carrying the device.

[0043] like Figure 5 As shown, in this embodiment, the first adjusting rope 204 or the second adjusting rope 205 has multiple fixing points between it and the webbing 202, or the first adjusting rope 204 or the second adjusting rope 205 has multiple connecting rope ends that connect to the webbing 202. This can form a claw-like connection structure, a concealed connection, or a multi-point connection, improving the stability of the connection and preventing the webbing 202 from detaching from the adjusting rope during carrying, ensuring the backpack remains stable during use and enhancing the user experience.

[0044] like Figure 7 As shown, in this embodiment, a skirt structure 30 is provided on the back edge of the back panel and / or the bag body. The skirt structure 30 can be made of webbing, fabric or leather, which can cover or decorate the gap between the back panel 20 and the bag body, and enhance the overall aesthetics.

[0045] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
