Description

Technical Field

[0001] The utility model belongs to the technical field of outdoor equipment, in particular to a safety backpack for outdoor activities. Background Art

[0002] With the rise in popularity of outdoor activities and increased safety awareness, the demand for outdoor safety backpacks is growing. While traditional outdoor backpacks provide basic storage, they often make it difficult for users to quickly locate and use safety equipment, such as whistles, in emergencies. This effectively compromises user safety. Furthermore, the design of traditional backpacks can easily cause small items like whistles to become entangled with other items, making them difficult and inconvenient to use.

[0003] Some existing backpacks have integrated whistles, but most lack automatic retracting mechanisms, which can cause the whistle to become tangled with other items when not in use or make it difficult to quickly retrieve and use in an emergency. To improve the safety and convenience of outdoor activities, there is an urgent need for an improved outdoor activity safety backpack that allows for convenient use of a whistle in an emergency while preventing it from becoming tangled with other items or becoming unremovable.
