Description

Diving knapsack Technical Field The application relates to the field of backpack, in particular to a backpack. Background In the field of diving operations, diving backpacks are one of the tools required by divers, backpacks are usually made of waterproof materials, and the opening of the backpack needs to be rolled up to form a rolling end during use, so that the possibility of water entering the backpack is reduced. The existing diving backpack is limited to the winding end by arranging a binding belt in the middle, so that the possibility of loosening the winding end is reduced, however, the binding belt is arranged in the middle, the limiting effect on the two ends of the winding end is poor, and the two ends of the winding end still have the possibility of loosening. Disclosure of utility model In order to reduce the possibility of unreeling two ends of a reeling end, the application provides a backpack. The application provides a diving backpack, which adopts the following technical scheme: The utility model provides a dive knapsack, includes the inclusion, the inside of inclusion has the chamber of holding, the upper portion of inclusion is provided with the opening that communicates in the chamber of holding, the upper portion of inclusion is rolled in order to form the rolling end, the middle part of inclusion is provided with first constraint area in order to carry out spacingly to the middle part of rolling end, the both ends of inclusion all are provided with first taut area, the both ends of rolling end all are provided with the taut area of second, first taut area is provided with the son and detains, the taut area of second is provided with the box, the son is detained and can be buckled in the box. Through adopting above-mentioned technical scheme, be provided with first taut area at the both ends that the inclusion is located the rolling end, and the both ends of rolling end are provided with the taut area of second, and the rolling end is after the rolling is accomplished, detain the lock in the box through the son to connect first taut area and the taut area of second, with take-up the both ends to the rolling end, thereby reduce the possibility that the rolling end both ends were loose.
