Description

Technical Field

[0001] The utility model relates to the technical field of backpacks, in particular to a two-way adjustable shock-absorbing backpack. Background Art

[0002] A trolley backpack is a portable travel device that combines the functions of a backpack and a suitcase. It is usually equipped with an aluminum alloy single pole and two or four rollers so that the user can easily drag the backpack. This type of backpack is particularly suitable for people who need to carry heavy objects or travel for a long time, because it can reduce the weight of the backpack and provide a more convenient way of movement.

[0003] For example, the Chinese utility model patent with the announcement number: CN212139711U discloses a trolley backpack, including a protective bracket, a bag body fixedly connected to the protective bracket and provided with a shoulder strap, a trolley mechanism installed on the protective bracket, the protective bracket is provided with a mounting cavity and a roller assembly movably retracted in the mounting cavity, the back of the bag body is provided with an interlayer, the trolley mechanism includes a fixed sleeve fixedly connected to the protective bracket and inserted into the interlayer of the bag body, a pulling rod slidably connected along the axial direction of the fixed sleeve, and a transmission assembly that drives the roller assembly to be retracted. The utility model has the effect of preventing dirt on the roller from getting on clothes when the user drags the bag body and uses it as a backpack, so as to keep the clothes clean.

[0004] However, the above technical solution and the trolley backpack in the prior art have poor shock absorption performance during the pulling process, and the position of the universal wheel is relatively fixed. The backpack can only be pulled vertically or horizontally according to the installation position of the universal wheel. The horizontally placed backpack usually provides more placement space, which is suitable for situations where more or larger items need to be carried, and can more effectively utilize the space of the backpack, especially for those irregularly shaped items. The vertically placed backpack provides a more convenient way to manage and find items. When the items in the backpack are relatively mixed, the vertical placement can allow users to find the required items more quickly and improve efficiency. Once the position of the universal wheel of the trolley backpack is fixed, it is difficult for users to choose to switch between horizontal and vertical pulling of the backpack, which affects the user experience. Utility Model Content
