[0013] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0014] Figure 1 It is a schematic diagram of the structure of the utility model;

[0015] Figure 2 for Figure 1 A partial enlarged schematic diagram of part I. DETAILED DESCRIPTION

[0016] See attached Figure 1 and 2 The uniform air trumpet-shaped aeration pipe comprises an air supply pipe 1 which is horizontally distributed on the upper side of the water surface, a plurality of uniformly distributed first through holes 2 are uniformly provided at the bottom of the air supply pipe, a valve body 3 is installed in the first through hole 2, the valve body comprises a fixed pipe 301, an external thread is provided on the outer side of the fixed pipe 301, an internal thread is provided on the first through hole 2, the fixed pipe is connected to the first through hole 2 by threads, a sliding pipe 302 is provided in the fixed pipe, an end cap 303 is fixedly provided at the inner end of the sliding pipe 302, and a plurality of second through holes 304 are provided on the inner end side of the sliding pipe 302 The outer end of the sliding tube 302 extends a portion from the outer end of the fixed tube. The outer end of the sliding tube is in the shape of a lock tongue with an arc-shaped surface facing one side. The sliding tube 302 is connected to the fixed tube by a spring 305. Under the elastic force of the spring 305, the sliding tube remains extended outward. At this time, the end cover 303 at the inner end of the sliding tube presses against the inner end of the fixed tube to keep it closed. After squeezing the sliding tube from the outside to the inside, the second through hole 304 at the inner end of the sliding tube is exposed from the inner end of the fixed tube. At this time, the inside of the air supply pipe is connected to the outside through the sliding tube.

[0017] See attached Figure 1A card slot 4 is provided at the top of the air supply pipe corresponding to the valve body position, and a card ring 5 with a notch is provided at the card slot position of the air supply pipe. The card ring 5 is made of elastic material, and a card block 6 matching the card slot 4 is provided at the bottom of the upper end of the card ring 5. A docking groove 7 matching the shape of the outer end of the sliding pipe is provided on the inner side of the lower end of the card ring 5. The bottom of the lower end of the card ring 5 is fixedly connected to the upper end of the aeration pipe 8, and the lower end of the aeration pipe 8 is connected to the trumpet-shaped aeration plate 9. The upper end of the aeration pipe is connected to the inside of the docking groove 7 through a third through hole 11.

[0018] When in use, the user first inserts the block 6 of the clamp ring 5 into the clamping groove 4, then holds the aeration tube and slightly applies force in the direction away from the air supply tube to open the notch of the clamp ring, and then moves the aeration tube in the direction of the air supply tube. Figure 1 In the direction of the middle arrow, the inner side of the clamping ring squeezes the outer end of the sliding tube, and the sliding tube slides inward a certain distance, the spring is compressed, and the clamping ring moves along with the aeration tube. Finally, under the elastic force of the spring, the outer end of the sliding tube is stuck in the groove docking groove. At this time, due to the design of the lock tongue shape, the docking groove and the outer end of the sliding tube are self-locking, and the clamping ring can be firmly stuck on the outside of the air supply pipe. The outer end of the sliding tube is docked with the third through hole. At this time, the inside of the air supply pipe is connected to the aeration plate through the second through hole, the sliding tube, the third through hole, and the aeration pipe. When the air supply pipe is intaken, the gas can be aerated through the aeration plate.

[0019] When removing the clamping ring, you only need to pull down the aeration tube so that the clamping ring opens and the docking groove separates from the outer end of the sliding tube, and then the clamping ring can be removed. A certain external force needs to be applied when removing it. The clamping ring can return to its original shape under its own elasticity and will not affect the next use.

[0020] This device can realize the rapid connection between the aeration pipe and the air supply pipe, and is also convenient for rapid removal later. The use of this design can quickly arrange the air supply pipe in a larger water pool, and can quickly install the aeration pipe on the air supply pipe. After removing the aeration pipe, the valve body can automatically seal. The opening and closing of the valve body is combined with the installation of the aeration pipe to realize the function of automatic opening of the valve body after installing the aeration pipe and automatic closing of the valve body after removing the aeration pipe, which greatly improves the work efficiency. The aeration pipes can be quickly and evenly distributed to achieve uniform aeration.

[0021] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
