Technical Field
[0001] This utility model relates to the field of backpack shoulder strap technology, and more particularly to a shoulder strap adjustment buckle structure. Background Technology
[0002] Backpacks are essential items for people when traveling, providing convenience for carrying belongings. Shoulder straps are a crucial component of a backpack; they are worn over the shoulders to support the backpack. (Appendix) Figure 5 This is a common shoulder strap structure for backpacks on the market. When you need to adjust the length of the shoulder strap, you have to use your fingers to pull the U-shaped adjustment ring out from the D-ring before adjusting the length of the shoulder strap. This can easily cause finger pain, making it inconvenient and quick to operate, and the user experience is not very good. Summary of the Invention
[0003] The problem to be solved by this utility model is to provide a shoulder strap adjustment buckle structure to improve the convenience of shoulder strap length adjustment and improve the comfort of use.
[0004] To solve the above technical problems, a shoulder strap adjustment buckle structure provided by this utility model is provided, which includes a shoulder strap, a D-ring buckle, and an adjustment buckle. The D-ring buckle includes a square ring and a connecting beam connected to the inner side of the square ring. The connecting beam divides the square ring into a first strap opening and a second strap opening. The adjustment buckle is provided with a strap inner ring. One end of the shoulder strap forms a hanging ring that fits on the connecting beam. The other end of the shoulder strap passes through the first strap opening, the strap inner ring, and the second strap opening in sequence to form a ring-shaped connecting end and a U-shaped adjustment ring on the shoulder strap.
[0005] Preferably, the adjusting buckle is provided with a locking plate on the side inside the U-shaped adjusting ring. By pulling the ring-shaped connecting end and one end of the shoulder strap in the opposite direction, the U-shaped adjusting ring can be tightened and the locking plate can be locked between the outer side of the hanging ring and the inner side of the U-shaped adjusting ring.
[0006] Preferably, one end of the card slot plate has evenly distributed toothed portions.
[0007] Preferably, the two ends of the inner ring of the thread are rounded.
[0008] Preferably, the adjusting buckle includes a U-shaped portion and a connecting section connecting the two ends of the U-shaped portion. The end of the connecting section is orthogonal to one end of the U-shaped portion, and the locking plate is connected to the outer surface of the connecting section.
[0009] The beneficial effects of this utility model are as follows: This utility model provides a shoulder strap adjustment buckle structure. In use, the loop-shaped connecting end is connected to the lower side of the backpack, and one end of the shoulder strap is connected to the upper side of the backpack. By setting an adjustment buckle on the U-shaped adjustment loop, when it is necessary to adjust the length of the shoulder strap, a finger is placed in the inner loop of the strap to pull up the adjustment buckle, which can easily and quickly enlarge the U-shaped adjustment loop and make it loose, at which point the length of the shoulder strap can be adjusted. After the shoulder strap length is adjusted, the loop-shaped connecting end and one end of the shoulder strap are pulled in the opposite direction to tighten the U-shaped adjustment loop and hold the adjustment buckle, thus positioning the buckle on the shoulder strap. Its structure is simple, which can improve the convenience of shoulder strap length adjustment, improve the comfort of using the backpack, and provide a better user experience.

Detailed Implementation
[0016] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure.
[0017] Based on the embodiments described in this disclosure, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this disclosure.
[0018] refer to Figure 1-5 .
[0019] This utility model provides a shoulder strap adjustment buckle structure, including a shoulder strap 1, a D-ring buckle 2, and an adjustment buckle 3. The D-ring buckle 2 includes a square ring 20 and a connecting beam 21 connected to the inner side of the square ring 20. The connecting beam 21 divides the square ring 20 into a first strap opening 200 and a second strap opening 201. The adjustment buckle 3 is provided with a strap inner ring 30. One end of the shoulder strap 1 forms a hanging ring 10 that fits on the connecting beam 21. The other end of the shoulder strap 1 passes through the first strap opening 200, the strap inner ring 30, and the second strap opening 201 in sequence, and then forms a ring-shaped connecting end 11 and a U-shaped adjustment ring 12 on the shoulder strap 1.
[0020] Its working principle is as follows: In use, the loop-shaped connecting end 11 is connected to the lower side of the backpack, and one end of the shoulder strap 1 is connected to the upper side of the backpack. An adjustment buckle 3 is set on the U-shaped adjustment loop 12. When the length of the shoulder strap 1 needs to be adjusted, a finger is placed in the inner loop 30 of the strap to pull up the adjustment buckle 3, easily and quickly widening the U-shaped adjustment loop 12 and slack off it, allowing for adjustment of the shoulder strap 1's length. After the shoulder strap 1 length is adjusted, the loop-shaped connecting end 11 and one end of the shoulder strap 1 are pulled in the opposite direction to tighten the U-shaped adjustment loop 12 and hold the adjustment buckle 3, thus positioning the D-ring buckle 2 on the shoulder strap 1. Its simple structure improves the convenience of shoulder strap length adjustment, enhances backpack comfort, and provides a better user experience.
[0021] Based on the above embodiments, the adjusting buckle 3 is provided with a locking plate 31 on the side inside the U-shaped adjusting ring 12. By pulling the ring-shaped connecting end 11 and one end of the shoulder strap 1 in the opposite direction, the U-shaped adjusting ring 12 can be tightened and the locking plate 31 can be locked between the outer side of the hanging ring 10 and the inner side of the U-shaped adjusting ring 12, which can lock the shoulder strap 1 and prevent the adjusting buckle 3 from moving on the shoulder strap 1.
[0022] Based on the above embodiments, one end of the locking plate 31 has evenly distributed toothed portions 310. When the locking plate 31 is locked between the outer side of the hanging ring 10 and the inner side of the U-shaped adjusting ring 12, it can increase the resistance of the bottom end of the locking plate 31 to the shoulder strap 1 and prevent the adjusting buckle 3 from moving on the shoulder strap 1.
[0023] Based on the above embodiments, the two ends of the inner loop 30 are rounded to reduce the wear of the inner loop 30 on the shoulder strap 1.
[0024] Based on the above embodiments, the adjustment buckle 3 includes a U-shaped part 32 and a connecting section 33 connected between the two ends of the U-shaped part 32. The end of the connecting section 33 is orthogonal to one end of the U-shaped part 32. The locking plate 31 is connected to the outer side of the connecting section 33. The distance between the two ends of the U-shaped part 32 is interference-fitted with the width of the shoulder strap 1, which plays a limiting role in the shoulder strap 1 and prevents the adjustment buckle 3 from turning during use.
[0025] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
