DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments:

[0025] As Figures 1-3 shown, the present utility model provides a balloon inflation nozzle with adjustable air leakage speed, which includes an inflation tube 1, a one-way valve core 2, a storage wheel 3, a plug 4, and an inflation transition plug 7. The one-way valve core 2 is slidably connected to the left inner surface of the inflation tube 1. The storage wheel 3 is arranged on the right inner surface of the inflation tube 1. The plug 4 and the inflation transition plug 7 are sequentially slidably inserted into the right end inner side of the inflation tube 1. A tether 5 is fixedly connected to the left side of the plug 4, and a counterweight 6 is fixedly connected to the left end of the tether 5. A helium gas cylinder 8 is arranged on the left side of the inflation transition plug 7. Sliding blocks 11 are arranged on the upper and lower sides of the left end outer surface of the inflation tube 1. Opposite surfaces of the two sliding blocks 11 are fixedly connected with connecting rods 12. Sliding grooves one are opened on the upper and lower sides of the left end inside of the inflation tube 1. One end of the connecting rod 12 away from the sliding block 11 penetrates into the inside of the sliding groove one. One end of the connecting rod 12 away from the sliding block 11 is fixedly connected with a right-angle baffle 13. The right-angle baffle 13 is slidably connected to the inside of the sliding groove one and the end away from the connecting rod 12 penetrates to the inner surface of the inflation tube 1;

[0026] The inflation tube 1 is a pipeline for inflation and air leakage and an installation bracket for the one-way valve core 2. Under normal circumstances, the one-way valve core 2 is closed. When the balloon is inflated, the helium gas cylinder 8 is inserted into the right end of the inflation tube 1 through the inflation transition plug 7 to inflate the balloon. The inflation pressure is greater than the internal pressure of the balloon, and the one-way valve core 2 opens, and helium gas enters the balloon. After inflation is completed, by squeezing the sliding block 11, the connecting rod 12 can be made to push the right-angle baffle 13 to block on the right side of the one-way valve core 2. After the one-way valve core 2 returns to its position, the one-way valve core 2 cannot be completely closed, and the gas in the balloon starts to leak at the designed rate. After covering the plug 4 at the right end of the inflation tube 1, the inflation nozzle can be completely sealed, and the helium gas in the balloon no longer leaks. When releasing a floating balloon, since the inflation nozzle and the counterweight 6 are greater than the buoyancy of the balloon, the balloon will not accidentally take off. It is necessary to remove the plug 4 and the counterweight 6 at the end of the inflation nozzle to fly. After the balloon is released, it starts to leak at the pre-designed rate until the buoyancy of the balloon is less than the weight of the balloon and then it starts to descend until it lands. For a moored balloon, it is normally prevented from taking off by the main tether tension. When the main tether accidentally falls off or breaks, etc., the tether 5 on the plug 4 is stretched and stressed, and the plug 4 of the inflation tube falls off, and the balloon immediately starts to leak and can fall in a short time. At the same time, the internal storage wheel 3 can be used for promotional advertisements, and the promotional advertisement content can be replaced at will, which is convenient to use.

[0027] As Figures 4-5As shown in the figure, the utility model provides a balloon inflating nozzle with adjustable air leakage speed. The plug 4 includes a cover plate 41. The cover plate 41 is arranged at the right end of the inflating tube 1. A connecting hook ring 42 is arranged on the right side of the cover plate 41. The outer surface of the connecting hook ring 42 is fixedly connected with the left end of the tether 5. The left side of the cover plate 41 is fixedly connected with a plug-in column 43. The plug-in column 43 is slidably inserted into the inner surface at the right end of the inflating tube 1. A sealing ring 44 is slidably connected to the right side of the outer surface of the plug-in column 43. A positioning mechanism 45 is arranged on the outer surface of the plug-in column 43. The positioning mechanism 45 includes a pulling rod 451. The pulling rod 451 is fixedly connected to the left side of the connecting hook ring 42. A second sliding groove is formed inside the plug-in column 43. The left end of the pulling rod 451 penetrates into the second sliding groove and is fixedly connected with a sliding pull plate 452. The sliding pull plate 452 is slidably connected inside the second sliding groove. Connecting plates 453 are movably connected to both the upper and lower sides of the sliding pull plate 452. One end of the connecting plate 453 away from the sliding pull plate 452 is movably connected with an L-shaped clamping plate 454. The two L-shaped clamping plates 454 are respectively slidably connected to the upper and lower inner walls of the second sliding groove. Tightening springs 455 are fixedly connected to the opposite surfaces of the two L-shaped clamping plates 454. One end of the tightening spring 455 away from the L-shaped clamping plate 454 is fixedly connected to the inner wall of the second sliding groove. An annular clamping groove 14 is formed in the inner surface at the right end of the inflating tube 1. One end of the L-shaped clamping plate 454 away from the L-shaped clamping plate 454 penetrates into the annular clamping groove 14. The right side of the end of the L-shaped clamping plate 454 close to the annular clamping groove 14 is an inclined surface;

[0028] When the plug 4 is inserted into the inflating tube 1, under the pushing of the tightening spring 455, the L-shaped clamping plate 454 can be made to snap into the annular clamping groove 14, so as to fix the plug 4, thereby closing the inflating tube 1. By pressing the sealing ring 44 through the cover plate 41, the right end of the inflating tube 1 can be sealed. When the balloon is released, only by pulling the tether 5, the connecting hook ring 42 can pull the pulling rod 451, so that the sliding pull plate 452 slides inside the second sliding groove, and the L-shaped clamping plate 454 can be pulled back from the annular clamping groove 14 through the connecting plate 453, so that the plug 4 can be pulled out, which facilitates the release of the balloon and makes the use of the balloon inflating nozzle more convenient.

[0029] Next, the working principle of the balloon inflating nozzle with adjustable air leakage speed will be specifically described.

[0030] As Figures 1-5As shown, when the balloon inflation nozzle is in use, helium can be filled into the balloon through the helium cylinder 8. The inflation pressure is greater than the internal pressure of the balloon, the one-way valve core 2 opens, and helium enters the balloon. After inflation, by squeezing the sliding block 11, the connecting rod 12 can be pushed to make the right-angle baffle 13 block on the right side of the one-way valve core 2, so that the one-way valve core 2 cannot be completely closed, and the gas in the balloon starts to deflate at the designed rate. Insert the plug 4 into the inflation tube 1. Under the pushing of the top spring 455, the L-shaped clamping plate 454 can be clamped into the internal of the annular clamping groove 14 to fix the plug 4, completely closing the inflation nozzle. Affected by the counterweight 6, the balloon will not accidentally take off. Then, removing the plug 4 and the counterweight 6 at the end of the inflation nozzle can release the balloon. After the balloon is released, it starts to deflate at the pre-designed rate until the buoyancy of the balloon is less than its weight and then starts to descend until it lands.

[0031] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
