Description

Technical Field

[0001] The utility model relates to the technical field of tourist backpacks, in particular to a supporting device for tourist backpacks. Background Art

[0002] A travel backpack is a backpack specifically used for traveling. It is a backpack that is easy to carry items. It is usually composed of shoulder straps, a back pad and a bag body. The design of the backpack is suitable for distributing the weight evenly on the shoulders, reducing the burden and making it more convenient to carry items.

[0003] Some existing tourist backpacks are made of cloth, and the tourist backpacks have no shape. When tourists climb mountains, the items in the backpacks will directly press the tourists' backs. When tourists climb mountains, their bodies will emit a lot of heat. When the tourist backpacks are in close contact with the tourists' backs, the tourists' backs will sweat a lot, which will reduce the tourists' experience. Moreover, when tourists climb mountains, the items in the backpacks are prone to collide with each other, causing damage to the items in the backpacks, and the items carried in the backpacks cannot be effectively protected.
