AI Technical Summary
The existing backpack straps have a narrow width and hardness. When the backpack straps are heavy, the shoulders are subjected to strong pressure, which can easily wear off the shoulder skin. When used in summer, the heat gathers in contact with the backpack straps, which makes them prone to sweating, making them very uncomfortable to use.
By arranging rubber cotton, the contact area between the backpack strap and the shoulder is increased, the flexibility is improved, and the pressure on the shoulder is reduced. In the summer, the rubber cotton filled with water is placed in the refrigerator to cool down and dissipate heat to avoid sweating.
Greatly reduce the pressure of the shoulder, reduce the shock of vibration, avoid friction and injury, improve comfort in summer, and avoid sweating.

DETAILED DESCRIPTION
[0021] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model. The experimental methods in the following embodiments are conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.
[0022] Embodiment:
[0023] like Figure 1-Figure 4 As shown, a load-reducing buffering shoulder strap comprises a rubber cotton 1, an inner groove is provided inside the rubber cotton 1, a water bag 2 is arranged inside the inner groove, a connecting pipe 3 is fixedly connected to one side of the water bag 2, a water inlet pipe 4 is arranged at the top of the connecting pipe 3, the top of the water inlet pipe 4 passes through the rubber cotton 1 and is located outside the rubber cotton 1, a sealing plug 5 is arranged inside the water inlet pipe 4, a groove is provided inside the sealing plug 5, a push-pull rod 9 is arranged inside the groove, a limiting groove 10 is provided on the surface of the push-pull rod 9, a ball 7 is arranged on one side of the push-pull rod 9, a card groove is provided on the inner wall of the water inlet pipe 4, and one side of the ball 7 is located inside the card groove;
[0024] The existing backpack straps are narrow and hard. When carrying heavy objects, the shoulders are subjected to great pressure, which can easily wear the shoulder skin. When used in summer, the shoulders and the backpack straps are in contact with heat, which can easily cause sweating and make the use very uncomfortable. By setting the rubber cotton 1, when in use, water is injected into the inner side of the water bag 2, and then the sealing plug 5 is covered, and the push-pull rod 9 is pressed. The push-pull rod 9 slides on the inner side of the groove, and the push-pull rod 9 pushes the sealing plug 5 to slide on the inner side of the water inlet pipe 4 until the sealing plug 5 completely enters the inner side of the water inlet pipe 4. The limiting groove 10 pushes the ball 7 from the inner side of the groove of the sealing plug 5 into the inner side of the card groove of the inner wall of the water inlet pipe 4, and the push-pull rod 9 continues to slide downward on the inner side of the groove, and the limiting groove 10 leaves the surface of the ball 7. The outer surface of the push-pull rod 9 contacts and squeezes the ball 7. The backpack strap is pressed on the rubber cotton 1, and the weight of the backpack makes the backpack strap press on the push-pull rod 9. The backpack strap and the shoulder squeeze the water inside the water bag 2, and the water pressure gives the sealing plug 5 an upward force on the inner side of the water inlet pipe 4, and transmits it to the ball 7 through the slot, and transmits a vertical force to the push-pull rod 9 through the ball 7. The push-pull rod 9 does not slide up and down, so that the ball 7 cannot return from the slot to the inner side of the groove, thereby completing the locking; by providing the rubber cotton 1, the contact area between the backpack strap and the shoulder is increased, the softness is improved, the pressure on the shoulder is greatly reduced, and when running, the vibration impact is reduced to avoid friction injuries. When used in summer, the rubber cotton 1 filled with water can be put into the refrigerator for cooling, so that the heat on the shoulder contact surface can be dissipated, sweating is avoided, and comfort is improved.
[0025] In other embodiments, the present embodiment discloses, please Figure 1 , Figure 2 and Figure 5 As shown, the top of the rubber cotton 1 is fixedly connected to a first strap 13, the bottom of the first strap 13 is provided with a second strap 16, the bottom of the second strap 16 is fixedly connected to the rubber cotton 1, the bottom surface of the first strap 13 is fixedly connected to a first Velcro 14, the top surface of the second strap 16 is fixedly connected to a second Velcro 15, and the bottom surface of the second strap 16 is fixedly connected to a barb 17;
[0026] During installation, open the first strap 13 and the second strap 16, put the backpack strap above the rubber cotton 1, and then wrap the second strap 16 around the backpack strap and squeeze it so that the barbs 17 are sunk into the backpack strap. Then wrap the first strap 13 around the second strap 16 and tighten it so that the first Velcro 14 and the second Velcro 15 fit tightly together to complete the installation. The first strap 13 and the rubber ring 6 are provided to facilitate installation and disassembly. When running, the barbs 17 can fix the second strap 16 and the backpack strap to prevent the rubber cotton 1 from loosening and moving from the backpack strap.
