[0023] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0024] Example 1
[0025] Combined with appendix Figure 1 and Figure 4 As shown, a shoulder protector clip for a backpack includes a shoulder protector clip body, which is sleeved on a bag strap 1. The shoulder protector clip body includes a shoulder protector strap 2, with a shoulder protector sponge 3 embedded in the shoulder protector strap 2. Multiple sets of connecting components are symmetrically arranged on one side of the shoulder protector strap 2. A cushioning component is provided on the shoulder protector strap 2, and a support plate 4 is connected to the cushioning component. The cushioning component includes a shock-absorbing spring 5 and a shock-absorbing spring 6. A tube body 7 is provided on the shoulder protector strap 2. A cushioning rod 8 is provided at the bottom of the support plate 4. The cushioning rod 8 is inserted into the tube body 7. A shock-absorbing spring 5 is sleeved on the outside of the tube body 7. One end of the shock-absorbing spring 5 is connected to the support plate 4, and the other end is connected to the shoulder protector strap 2. A movable plate 9 is provided at the bottom of the cushioning rod 8, and a shock-absorbing spring 6 is connected to the movable plate 9. The shock-absorbing spring 6 is sleeved on the outside of the cushioning rod 8, and one end of the shock-absorbing spring 6 is connected to the tube body 7.
[0026] Through the above structure, the shoulder pad sponge 3 can absorb the vibration and force generated by the bumps on the road when walking, thereby reducing the pressure on the shoulder. At the same time, the shoulder pad sponge 3 can evenly distribute the surface pressure, making the force on the shoulder more even and reducing the local burden. Meanwhile, the cushioning component can reduce the vibration to a certain extent by means of the interaction of the shock-absorbing spring 5 and the shock-absorbing spring 6.
[0027] Combined with appendix Figure 3As shown, the shoulder pad sponge 3 is made of polyether-type polyurethane foam sponge, the side of the shoulder pad strap 2 that contacts the human body has a breathable mesh structure, the surface of the shoulder pad strap 2 is made of waterproof fabric, and the width of the shoulder pad strap 2 is greater than the width of the bag strap 1.
[0028] Through the above structure, polyether-type polyurethane foam sponge is also known as memory foam. Its characteristics are slow rebound, good shock absorption and vibration reduction performance. One side of the shoulder strap 2 has a mesh structure, which has good breathability and improves the user's comfort. The waterproof fabric of the shoulder strap 2 improves the waterproof performance of the shoulder strap 2.
[0029] Example 2
[0030] Based on Example 1, and in conjunction with Appendix Figure 2 and Figure 3 As shown, there are two sets of connecting components. One set of connecting components includes connecting bolts 10 fixed on the shoulder strap 2. There are two connecting bolts 10 in one set. The strap 1 has through holes 11 that cooperate with the connecting bolts 10. The connecting bolts 10 are covered with nuts 12 that are compatible with them. The support plate 4 is made of rubber. One side of the support plate 4 is provided with a Velcro burr surface 13. The side of the strap 1 that contacts the support plate 4 is provided with a Velcro round burr surface 14.
[0031] With the above structure, the connecting bolt 10 passes through the through hole 11 and is tightened with the nut 12, thus achieving a fixed connection between the shoulder strap 2 and the bag strap 1. The rubber support plate 4 can be bent for easy use. The support plate 4 and the bag strap 1 are bonded by the cooperation of the Velcro round nap 14 and the Velcro barbed nap 13.
[0032] The specific usage method is as follows:
[0033] First, pass the connecting bolt 10 through the hole 11 on the bag strap 1 and tighten it with the nut 12 to complete the connection between the shoulder pad strap 2 and the bag strap 1. When the user carries the backpack, the shoulder pad sponge 3 made of polyether polyurethane foam is deformed under force, so that the surface pressure is evenly distributed. Through stress relaxation, it adapts to the surface shape of external pressure, so that the pressure at the highest point is reduced to the lowest level, thereby reducing the pressure on the shoulder.
[0034] At the same time, when the buffer component is under force, the support plate 4 presses down and drives the buffer rod 8 to move down, causing the shock-absorbing spring 5 to contract and the shock-absorbing spring 6 to stretch. The two make opposite movements and generate two opposite forces to resist the vibration, thereby reducing the burden on the shoulder and improving the shoulder protection ability.
[0035] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
