Description

Technical Field

[0001] The utility model relates to a backpack, in particular to a shock-absorbing and load-reducing backpack. Background Art

[0002] There are various types of backpacks that can reduce the weight of a backpack on the market, and they usually achieve this by installing elastic parts on the shoulder straps or back panels. For example, the utility model with the authorization announcement number CN207514542U discloses a backpack load-reducing device, which includes a backpack with a hollowed-out back, a backboard connected to the backpack to form a closed space, and shoulder straps. The lower end of the shoulder straps is connected to the backboard, and the upper end passes through the backboard and is connected to a spring damping mechanism arranged on the inner side of the backboard. When a person is walking with a load, the spring damping mechanism causes a phase difference between the vibration of the backpack's weight and the vibration of the human body, thereby reducing the pressure of the weight on the human trunk. However, since the two shoulder straps are independent and not formed into a whole by a connecting piece, when a user with uneven shoulders or a bad backpack-wearing habit uses the backpack, the two shoulder straps will be unevenly stressed, causing most of the weight of the backpack to act on one shoulder strap, affecting the user's experience. Summary of the Invention

[0003] The problem to be solved by the utility model is to provide a shock-absorbing and load-reducing backpack, which can evenly apply force to the shoulder straps and reduce the shaking amplitude when used by users.

[0008] As an improvement, the connecting part is provided with a third connecting hole and a limiting belt for limiting its moving range. The third connecting hole is arranged between the first connecting hole and the second connecting hole. One end of the limiting belt passes through the third connecting hole and is connected to the T-shaped limiting plate, and the other end of the limiting belt is fixed on the package body.

[0009] As an improvement, the bag body is provided with a connecting assembly, and the spring is fixedly connected to the bag body via the connecting assembly.

[0010] As an improvement, the connecting assembly includes a connecting belt fixed on the back of the bag body and a connecting plate connected to the connecting belt; the two ends of the connecting belt are fixed at the same position of the bag body, and the connecting belt forms a loop; the connecting plate passes through the loop and extends from both ends of the loop.

[0011] As an improvement, two fourth connecting holes are provided on the connecting plate, and the two fourth connecting holes are respectively provided on both sides of the connecting belt. The lower end of the spring passes through the fourth connecting hole and is connected to the connecting plate. The two fourth connecting holes correspond to two springs, and the two springs correspond to two second connecting holes, and the two second connecting holes are symmetrical to each other.

[0012] The beneficial effects of the present invention are as follows: by setting up a T-shaped limit plate, the two springs and the two shoulder straps are connected into a whole, and the user can avoid the problem of uneven force on the user due to problems such as high and low shoulders during use; at the same time, the limit parts on both sides of the T-shaped limit plate and the unstitched area on the back panel control the movement of the T-shaped limit plate in the lateral direction, and the limit belt controls the movement of the T-shaped limit plate in the longitudinal direction; so that the user will not cause the shoulder strap to shake greatly due to the shaking of the bag body during use, which has a shock-absorbing effect; the elastic force of the spring can also play a certain role in reducing the burden on the user; the upper end of the shoulder strap can move in the first connecting hole, and when facing users of different body shapes, the shoulder strap can be adjusted to a suitable position to enhance the user experience.

The lower ends of the shoulder straps 8 are fixed to the bag body 1, and the upper ends of the shoulder straps 8 are provided with ears 81. The ears 81 pass through the first connecting hole 31 and are connected to the T-shaped limiting plate 3. The ears 81 can move in the first connecting hole 31, so that the two shoulder straps 8 can be expanded or retracted. When facing users of different body shapes, they can be adjusted to the appropriate position by themselves, thereby improving the user experience; the second connecting hole 32 is provided at the lower part of the connecting part 35, and the two springs 4 correspond to the two second connecting holes. The upper end of the spring 4 passes through the second connecting hole 32 and is connected to the T-shaped limit plate 3. The lower end of the spring 4 is provided with a connecting assembly, and the lower end of the spring 4 is connected to the bag body 1 through the connecting assembly; the connecting assembly includes a connecting belt 7 fixed to the bag body 1 and a connecting plate 5 provided on the connecting belt 7.
