Description

Technical Field

[0001] This utility model relates to the field of crossbody bag technology, specifically a crossbody bag strap structure. Background Technology

[0002] A crossbody bag is a stylish and practical bag, typically featuring a long shoulder strap that allows the user to wear the bag across their body. This design is not only convenient to carry but also effectively distributes weight. Crossbody bags are very popular in daily life and suitable for various occasions and styles. They are perfect for daily outings, travel, work, and leisure activities, and can be paired with a variety of clothing styles. In recent years, crossbody bag designs have become increasingly diverse, including mini versions, collaborations, and styles made from environmentally friendly materials, giving consumers more choices. In addition, many high-end brands and designers have launched their own crossbody bag collections, increasing market competitiveness.

[0003] In existing crossbody bags, the shoulder straps are usually connected by fixed stitching. This connection method is very inconvenient when assembling and disassembling the shoulder straps. In addition, after long-term use, the shoulder straps may not only slip off, but may also cause shoulder discomfort, thereby reducing the comfort and protection of the shoulder straps. At the same time, this design also affects the efficiency of assembling and disassembling the shoulder straps. Therefore, we propose a crossbody bag shoulder strap structure. Utility Model Content

Detailed Implementation

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] This utility model provides a technical solution: such as Figures 1-6 As shown, in this embodiment, a crossbody bag strap structure includes a bag body 1. Rotating blocks 10 are rotatably connected to both sides of the bag body 1. Each rotating block 10 has a slot 8 at its top and two grooves 9 on both sides. The four grooves 9 communicate with the interior of the two slots 8. A strap body 2 is fixedly connected between the tops of the two rotating blocks 10. A connecting groove 14 is provided at one end of the strap body 2. A fixing ring 4 is rotatably connected to both the connecting groove 14 and the inner side of the strap body 2. A snap-fit ​​structure is provided at the bottom of the two fixing rings 4. An adjusting block 7 is slidably connected to the outer side of the strap body 2. A fixing structure is provided on one side of the adjusting block 7. An anti-slip shoulder pad 6 is slidably connected to the outer side of the strap body 2. A retaining ring 5 is slidably connected to the outer side of the strap body 2.

[0016] When using the crossbody bag, the two fixing rings 4 are first connected to the shoulder strap body 2 and the connecting groove 14. At the same time, the connection between the shoulder strap body 2 and the bag body 1 is completed by the cooperation between the set snap-fit ​​structure and the two slots 8 and four grooves 9. Then, according to the usage needs, the user can pull one end of the shoulder strap body 2 by adjusting the set fixing structure, so that the shoulder strap body 2 moves between the inner walls of the adjusting block 7, so that the shoulder strap body 2 is adjusted to the required length. Then, the fixing structure is adjusted again to fix the shoulder strap body 2 to prevent it from sliding. Then, under the action of the snap ring 5, one end of the shoulder strap body 2 is fixed to prevent it from getting tangled. Then, the anti-slip shoulder pad 6 prevents the shoulder strap body 2 from slipping and protects the user's shoulder. At the same time, the design of the two rotating blocks 10 makes it easier for the user to use. This improves the convenience of assembling and disassembling the crossbody bag shoulder strap and the comfort.

[0017] like Figures 1-6 As shown, the mounting structure includes two connecting blocks 3, which are fixedly connected to the bottom of two fixing rings 4 respectively. Each of the two connecting blocks 3 has a guide groove 22 at its bottom. A guide rod 15 is fixedly connected between the inner walls of the two guide grooves 22. Two inserts 12 are slidably connected to the outer sides of the two guide rods 15. The outer sides of the four inserts 12 are in contact with the inner sides of the two slots 8 respectively. A protrusion 13 is fixedly connected to one side of each of the four inserts 12. The outer sides of the four protrusions 13 are in contact with the inner sides of the four grooves 9 respectively. Two return springs 16 are fixedly connected between the four inserts 12 and to the outer sides of the two guide rods 15 respectively.

[0018] By having four protrusions 13 slide between the inner walls of the two slots 8, the four inserts 12 move between the inner walls of the guide grooves 22 at the bottom of the two connecting blocks 3. At the same time, they press the return springs 16 made of high carbon steel on the outer sides of the two guide rods 15. Then, the return springs 16 made of high carbon steel push the four protrusions 13 to move, so that the four protrusions 13 contact the inner sides of the four grooves 9, thereby improving the convenience of the crossbody bag strap.

[0019] like Figures 1-6 As shown, the fixing structure includes a U-shaped groove 20, a fixing rod 18 is fixedly connected between the inner walls of the U-shaped groove 20, two fixing blocks 21 are rotatably connected to the outer side of the fixing rod 18, a rocker plate 17 is fixedly connected between the tops of the two fixing blocks 21, a biting block 11 is fixedly connected to one side of the rocker plate 17, and a torsion spring 19 is fixedly connected to the outer side of the fixing rod 18, with one end of the torsion spring 19 contacting the bottom of the rocker plate 17.

[0020] By pressing the rocker arm 17, the two fixed blocks 21 rotate between the inner walls of the U-shaped groove 20 and rotate on the outside of the fixed rod 18, thereby pressing the torsion spring 19 made of high carbon steel, thus lifting the bite block 11. When the rocker arm 17 is released, the torsion spring 19 made of high carbon steel drives the rocker arm 17 to lower the bite block 11, thereby improving the adjustment efficiency of the crossbody bag strap.

[0021] This utility model provides a crossbody bag strap structure, the specific working principle of which is as follows: When the crossbody bag is in use, firstly, the two fixing rings 4 are connected and engaged with the strap body 2 and the connecting groove 14. At the same time, the four protrusions 13 slide between the inner walls of the two slots 8, causing the four inserts 12 to move between the inner walls of the guide grooves 22 at the bottom of the two connecting blocks 3. Simultaneously, the return springs 16 made of high carbon steel are pressed on the outer sides of the two guide rods 15. Then, the return springs 16 made of high carbon steel push the four protrusions 13 to move, so that the four protrusions 13 contact the inner sides of the four grooves 9, thereby completing the connection between the strap body 2 and the bag body 1. Then, according to the usage requirements, by pressing the rocker arm 17, the two fixing blocks 21 are rotated between the inner walls of the U-shaped groove 20. The outer side of the fixed rod 18 rotates, thereby pressing the torsion spring 19 made of high carbon steel, which lifts the bite block 11. The user can pull one end of the shoulder strap body 2, so that the shoulder strap body 2 moves between the inner walls of the adjusting block 7, and adjusts the shoulder strap body 2 to the required length. Then, when the user releases the rocker arm 17, the torsion spring 19 made of high carbon steel drives the rocker arm 17 to lower the bite block 11, fixing the shoulder strap body 2 to prevent it from slipping. Then, under the action of the retaining ring 5, one end of the shoulder strap body 2 is fixed to prevent it from getting tangled. Then, through the action of the anti-slip shoulder pad 6, the shoulder strap body 2 is prevented from slipping while protecting the user's shoulder. At the same time, the design of the two rotating blocks 10 makes it easier for the user to use the crossbody bag, thus completing the connection and use of the crossbody bag shoulder strap.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
