Description

Technical Field

[0001] The utility model belongs to the technical field of tents, and in particular relates to an inflatable tent frame and an inflatable tent. Background Art

[0002] Airbag inflatable structures are widely used in civil and military fields due to their simple structure, light weight, easy operation, and quick construction and dismantling. Airbag inflatable structures are rigid structures constructed by the pressure difference between the inside and outside of the airbag, and are covered with rainproof tarpaulins to build large indoor spaces. The airtightness of the airbag and the sudden change of temperature outside will affect the pressure inside the airbag, thereby affecting the structural stability of the inflatable structure. Therefore, inflatable tents usually need to be equipped with a pressure monitoring system for pressure monitoring and regular air replenishment. However, in outdoor conditions, in special environments such as lack of power supply, it is impossible to ensure that the pressure in the airbag remains stable for a long time. Utility Model Content
