Description

Technical Field

[0001] The utility model relates to the technical field of negative pressure tents, in particular to a wire drawing cloth negative pressure tent. Background Art

[0002] When the number of isolation wards in a medical structure is insufficient, temporary negative pressure isolation tents are often used. The existing negative pressure tents supported by steel frames are not quick to set up, and the hard metal can easily wear out the tarpaulin. Inflatable negative pressure tents can solve this problem well, but the existing inflatable negative pressure tents are mostly air column frame type. Due to the air column structure, this type of tent has many connection points and is prone to air leakage. The air column structure tent has weak pressure bearing capacity and does not have thermal insulation properties. Inflatable frame negative pressure tents often add thermal insulation edges inside to give them thermal insulation functions, which results in a heavy weight of the tent.

[0003] The patent publication number CN213774760U was retrieved, and the patent name is a public material of a combined negative pressure tent, and specifically discloses a combined negative pressure tent, including a tent body, an air duct is connected through the lower part of the side of the tent body, a connecting plate is inlaid on the end of the air duct, a connecting tube is fittedly installed on the side of the connecting plate, a negative pressure pump is connected to the side of the connecting tube, a first barrier ring and a second barrier ring are extended from the side of the connecting plate, and the second barrier ring is located on the inner side of the first barrier ring, the first barrier ring and the second barrier ring are both slid through the inside of the connecting tube, two groups of extension blocks are extended from the front and rear ends of the connecting plate, and the connecting tube Two groups of fixed slot plates are extended from the front and rear ends, and one side outer surface of the two groups of fixed slot plates are respectively attached to the one side outer surface of the two groups of extension blocks, and two groups of transfer fixtures are installed on the one side outer surface of the two groups of extension blocks, and the two groups of transfer fixtures are respectively fixed to the other side outer surface of the two groups of fixed slot plates. The utility model can place the connecting plate on the air guide tube on the connecting tube on the negative pressure pump, and at the same time, the fixing plate on the extension block passes through the square groove on the fixing slot plate, and then the fixing plate is rotated ninety degrees so that the fixing plate and the square groove are staggered, so as to fix the extension block and the fixed slot plate together, and then fix the connecting plate and the connecting tube together, so that the tent body and the negative pressure pump can be combined together for use.

[0004] By analyzing the above-mentioned public materials, it can be seen that the negative pressure tent adopts an air column frame type, which has many connection points and has the risk of air leakage. It also has poor thermal insulation performance and poor noise reduction function. Utility Model Content
