[0026] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0027] like Figures 1 to 5 As shown, this embodiment discloses an adjustable backpack clip 10. The backpack clip 10 includes a main body 20 and a base plate 11. The two ends of the base plate 11 are respectively provided with a base plate pivot 12 and a limiting rod 13. One end of the main body 20 is movably connected to one end of the base plate 11 through the base plate pivot 12. The other end of the main body 20 is provided with a hook 21 and an adjustment mechanism 30. The hook 21 is movably connected to the adjustment mechanism 30 through a hook pivot 22. The hook 21 is provided with at least two parallel limiting slots 23. The other end of the base plate 11 can cooperate with any of the limiting slots 23 through the limiting rod 13.

[0028] By setting up a movable connecting hanging component, when installing the backpack clip 10, the limiting rod 13 can be adjusted to cooperate with different limiting slots 23 according to the actual thickness of the shoulder strap, achieving a stable clamping effect and having good compatibility. Furthermore, the base plate pivot 12 allows the base plate 11 to open and close easily, better accommodating shoulder straps of different shapes. Compared with the spring clip type backpack clip 10, it is more convenient and labor-saving to operate, adapting to shoulder straps of various shapes and sizes, and improving the practicality and flexibility of the backpack clip 10. At the same time, the hook 21 is movably connected through the hook pivot 22, giving the hook 21 a certain amount of play, which not only increases the range of motion of the hook 21, but also can buffer the impact force generated by the backpack on the backpack clip 10 during movement to a certain extent, protecting the safety of the backpack clip 10 and the backpack. The adjustment mechanism 30 includes a connecting rod 31, a connecting rod pivot 32, and a locking assembly 33. The middle part of the connecting rod 31 is mounted on the main body 20 via the connecting rod pivot 32. One end of the connecting rod 31 is movably connected to the hook 21 via the hook pivot 22. The locking assembly 33 is mounted on the main body 20 and cooperates with the other end of the connecting rod 31. Since the connecting rod 31 is connected to the main body 20 via the connecting rod pivot 32, it has a certain range of motion. To address the differences in backpack strap thickness for different specifications, an innovative four-stage adjustment scheme is adopted, namely, four gradient-distributed limiting slots 23 are configured on the hanging component. The extended limiting slot 23 structure design can adapt to ultra-wide shoulder strap usage scenarios. Combined with the multi-dimensional adjustable mechanism, the backpack clip 10 can adapt to various needs. It is equipped with various irregularly shaped shoulder straps and different sizes, which significantly improves the product's environmental adaptability and ease of operation. The locking component 33 includes an operating handle 34 and a cam shaft 35. The operating handle 34 includes a handle part 341 and a cam part 36. The cam part 36 is mounted on the main body 20 through the cam shaft 35. The cam part 36 cooperates with the end of the connecting rod 31, so that the user can easily control the movement state of the connecting rod 31 through the operating handle 34, thereby adjusting the position of the hanging component. When needed, the limit rod 13 can be adjusted to cooperate with different limit slots 23 according to the actual thickness of the shoulder strap. Simply rotate the operating handle 34 to make the cam part 36 apply appropriate pressure to the connecting rod 31 to achieve the locking function and ensure the stability and safety of the hanging component.

[0029] During the operation of the locking mechanism, the user drives the cam 36 to move around the pivot by rotating the control handle 341, applying a precise lever force to the connecting rod 31, causing a specific end of the connecting rod to tightly abut against the limiting structure on the inner wall of the main body 20. The device adopts an ergonomic handle shape, and by optimizing the lever arm ratio and transmission trajectory, the user can easily complete the locking / unlocking action with just one hand, significantly improving the ease of operation and user experience.

[0030] The main body 20 includes a fixed base 25, on which the adjustment mechanism 30 is mounted. The main body 20 has a mounting recess 24, within which the fixed base 25 is nested, effectively concealing the adjustment mechanism 30 and resulting in a simpler and more aesthetically pleasing overall appearance. The fixed base 25 has a baffle 253, which limits the rotational movement of the operating handle 34. The baffle 253 not only ensures the stability of the operating handle 34 during rotation but also prevents structural damage due to excessive rotation. Figure 4 As shown, Figure a1 on the left shows the locked state of the adjusting mechanism 30, and Figure a2 on the right shows the unlocked state of the adjusting mechanism 30. The main body 20 is provided with a first positioning hole 251 and a second positioning hole 252. The cam part 36 is provided with a limiting hole 361. A compression spring 362 and a steel ball 363 are provided in the limiting hole 361. The diameter of the steel ball 363 is larger than the diameter of the first positioning hole 251 and the second positioning hole 252. When the operating handle 34 is rotated, the steel ball 363 is pressed against the end of the compression spring 362. When the edge of the steel ball 363 rolls on the inner wall of the fixed seat 25 to the next positioning hole, the edge of the steel ball 363 will roll along the trajectory line 254 of the inner wall of the fixed seat 25. The compression spring 362 returns the steel ball 363 to achieve positioning, which makes it convenient for the user to adjust the strap. During installation, to prevent the operating handle 34 from moving freely and affecting the installation, when the steel ball 363 reaches the first positioning hole 251 or the second positioning hole 252, there is a noticeable resistance that is released, effectively reminding the user that the unlocking and locking states are in place. Rotating the operating handle 34 controls the steel ball 363 to engage with the first positioning hole 251 or the second positioning hole 252 to achieve the locking or unlocking state of the connecting rod 31. When the cam part 36 rotates to a specific angle, the steel ball 363, under the elastic force of the compression spring 362, will embed into the first positioning hole 251 or the second positioning hole 252, forming a stable locking state, effectively preventing the connecting rod 31 from moving accidentally when not in operation, thereby further adjusting the fixed angle and stability of the hanging component. When unlocking is required, the user only needs to rotate the operating handle 34 in the opposite direction, causing the cam part 36 to move the steel ball 363 out of the current positioning hole, thus easily achieving the unlocking operation. The entire process is smooth and stable, providing great convenience to the user. In addition, the design fully considers safety factors. Even in the event of an accident, such as when the operating handle 34 is subjected to an external impact, the elastic force of the compression spring 362 and the steel ball 363 can effectively prevent the linkage 31 from suddenly unlocking, ensuring a secure connection between the backpack clip 10 and the shoulder strap.

[0031] The main body 20 is provided with a cover plate 27 opposite to the base plate 11 and a shaft hole 26 for accommodating the base plate rotating shaft 12. The shaft hole 26 includes a first side wall 261 and a second side wall 262, which are perpendicular to the cover plate 27. The first side wall 261 and / or the second side wall 262 are provided with at least two parallel limiting grooves 263, and the base plate rotating shaft 12 can move along the shaft hole 26 into any one of the limiting grooves 263. The shaft hole 26 is provided with three limiting grooves 263, which have three adjustable positions that can be selected according to the thickness of the strap. The base plate 11 has a base plate pivot 12 that can rotate and move to different positions within three preset positions. A limiting rod 13 is fixed to the other end of the base plate 11. When the base plate 11 is passed through the backpack strap, the operating handle 34 is opened, and the limiting rod 13 is hooked into the limiting slot 23 of the hook 21. This hook 21 has four limiting slots 23. After selecting the appropriate position according to the backpack strap thickness, rotating and pressing the operating handle 34 locks the backpack strap. The adjustment mechanism 30 uses a lever principle and, in conjunction with the rotation of the operating handle 34, achieves locking or unlocking. This design allows the backpack clip 10 to adapt to backpack straps of different widths, improving its practicality and versatility. During use, the user only needs to select the appropriate limiting groove 263 and the appropriate position of the limiting slot 23 according to the actual width of the backpack strap to easily clamp and fix the backpack strap. Simultaneously, due to the lever principle, the rotation of the operating handle 34 easily achieves locking or unlocking, making the backpack clip 10 more convenient to use. In addition, the backpack clip 10 has the advantages of simple structure, easy manufacturing and maintenance, and can meet the needs of a wide range of users.

[0032] The base plate 11 is equipped with a first anti-slip pad 14, and the cover plate 27 is equipped with a second anti-slip pad 271. When the base plate 11 is rotated and fastened to the main body 20, the first anti-slip pad 14 and the second anti-slip pad 271 correspond to each other, effectively preventing the backpack clip 10 from sliding or shifting during use, thus improving safety and convenience. Furthermore, the soft texture of the anti-slip pads effectively protects the surface of the shoulder straps, preventing wear or scratches during clamping. Both the optional first anti-slip pad 14 and the second anti-slip pad 271 are made of materials with a high coefficient of friction, providing excellent anti-slip performance and maintaining the backpack's stability even in wet and slippery environments.

[0033] The main body 20 includes an adapter 15 for mounting digital devices. The adapter 15 is located on the opposite surface of the base plate 11. Its design allows users to easily attach various digital devices, such as mobile phones, action cameras, mirrorless cameras, or SLR cameras, to the backpack strap for convenient access. Optionally, the adapter 15 can be equipped with various interfaces and mounting slots to accommodate different sizes and types of digital devices, ensuring a secure installation and preventing them from falling off due to movement or bumps. The main body 20, base plate 11, and hook 21 are all made of aluminum alloy, ensuring product strength and effectively controlling weight. The mechanical fastening mechanism not only has strong load-bearing capacity but is also easy to operate.

[0034] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
