DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] An external thread groove 13 is provided on the outer tube wall of the connecting tube 1 , and an internal thread sleeve 14 is threadedly sleeved on the top of the connecting tube 1 through the external thread groove 13 .

[0022] A sealing groove 4 is provided on the outer tube wall of one end of the leak-proof tube 2 inserted into the annular groove 3 , and a sealing ring 5 is embedded in the sealing groove 4 . The sealing ring 5 can effectively improve the sealing performance between the leak-proof tube 2 and the annular groove 3 .

[0023] The anti-leakage tube 2 is inserted into the bottom of one end of the annular groove 3 and is fixedly connected with a spring 6, and the other end of the spring 6 contacts the inner bottom of the annular groove 3. The elastic force of the spring 6 can push the anti-leakage tube 2 upward, so that the sealing plate 9 fits with the sealing ring 10.

[0024] A limiting ring 11 is fixedly connected to the inner tube wall of the leak-proof tube 2. The setting of the limiting ring 11 can effectively limit the downward pressure of the leak-proof tube 2 and facilitate the docking of the connecting tube and the inflation tube.

[0028] When in use, remove the internal threaded sleeve 14 and insert the end of the inflation tube into the interior of the leak-proof tube 2. The mouth of the inflation tube contacts the limiting ring 11, thereby pushing the leak-proof tube 2 toward the inside of the connecting tube 1, so that there is a gap between the sealing plate 9 and the sealing ring 10, and the gas can be pumped into the interior of the inflatable tent through the air pump at the other end of the inflation tube. After the inflation is completed, release the inflation tube, and the leak-proof tube 2 is lifted upward under the elastic force of the spring 6, so that the sealing plate 9 fits with the sealing ring 10 to prevent the gas inside the inflatable tent from leaking along the connecting tube 1 and the leak-proof tube 2, and then the internal threaded sleeve 14 is threadedly sleeved on the connecting tube 1.
