Description

Technical Field

[0001] The utility model relates to an inflatable tent, in particular to an inflatable tent based on a mesh cloth. Background Art

[0002] An inflatable tent is a type of tent. The frame is designed based on the principles of structural mechanics. The gas pressure characteristics are used to inflate the airbag to form a column with a certain rigidity, and the frame of the tent is supported by an organic combination. An inflatable tent is also called a closed air tent. It can be used continuously after being inflated once. Existing inflatable tents such as the flat-top closed air inflatable tent previously disclosed by the applicant with publication number CN217151493U have a frame consisting of a frame monomer, a longitudinal middle beam and a longitudinal side beam, all of which are composed of a cylindrical heavy pulp frame cloth and a closed TPU liner. The respective liners are connected by connecting pipes. This frame is similar to a tire with an inner tube. The TPU liner is used for inflation to form a rigid support, and the heavy pulp frame cloth is used for shaping and protecting the TPU liner. The overall cost is high and the weight is relatively heavy. Utility Model Content
