[0022] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the attached drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects according to the present utility model as follows.

[0023] Please refer to Figures 1 to 5, this embodiment provides a trampoline with an airbag fence, including an airbag 1. There is a door opening 106 in the middle lower part of the front of the airbag 1. Children enter the inner circle of the airbag 1 through the door opening 106 and climb onto the trampoline 2 to play. Above the door opening 106, there is an upper connecting bag 102. On both sides of the upper connecting bag 102, there are support column bags 101. The support column bags 101 are fixedly connected to the upper connecting bag 102. The upper connecting bag 102 connects the upper ends of the support column bags 101 together, pulling and supporting the support column bags 101 so that they do not fall over. At the same time, it also protects children from accidentally jumping out of the top of the lower connecting bag 103. The structures of the other three sides of the airbag 1 are the same. At both ends of the other three sides of the airbag 1, there are support column bags 101. The support column bags 101 are fixedly connected to the support column bags 101 on the adjacent sides. The support column bags 101 at the four corners are not disconnected from top to bottom, providing support force for the entire airbag 1. There is a corner bag 104 between the support column bags 101 on the adjacent sides. The corner bag 104 is of the same height as and fixedly connected to the support column bags 101. The corner bag 104 fixes the support column bags 101 on the adjacent two sides together, increasing the connection area between the support column bags 101 and improving the integrity of the airbag 1. At the bottom of one side of the support column bag 101, there is a lower connecting bag 103. The lower connecting bag 103 is fixedly connected to the support column bag 101. The lower connecting bag 103 connects the lower ends of the support column bags 101 together, not only increasing the stability of the airbag 1 but also preventing children from falling. At the top of one side of the support column bag 101, there is an upper connecting bag 102. The upper connecting bag 102 is fixedly connected to the support column bag 101. There is an observation window 105 between the upper connecting bag 102 and the lower connecting bag 103. Parents can clearly see the situation of the children on the trampoline 2 through each observation window 105. If an accident occurs, they can provide help in time. There is a support column bag 101 between the observation windows 105. The support column bag 101 is fixedly connected to both the upper connecting bag 102 and the lower connecting bag 103. Inside the airbag 1, there is an air chamber 107. The air chambers 107 are independent of each other. After being inflated, the air chambers 107 can support the airbag 1.

[0024] Inside the airbag 1, there is an inflation pipeline 3. The inflation pipeline 3 includes a horizontal air pipe 303. The horizontal air pipe 303 runs through all the support column bags 101, the lower connecting bag 103, and the corner bags 104, bringing the air outlet 304 into each air chamber 107. The horizontal air pipe 303 is fixedly connected to the support column bags 101, the lower connecting bag 103, and the corner bags 104.

[0025] At the top of the horizontal air pipe 303, there is an air nozzle 302. The air nozzle 302 is fixedly connected to the horizontal air pipe 303. The air nozzle 302 runs through the airbag 1. Air is inflated into the inflation pipeline 3 through the air nozzle 302. Inside the air nozzle 302, there is a plug 301. The plug 301 is movably connected to the air nozzle 302. The diameter of the plug 301 is smaller than the diameter of the air nozzle 302. The plug 301 is inserted into the air nozzle 302 to prevent the airbag 1 from leaking air, reducing its strength and losing its protective effect on the trampoline 2.

[0026] An air outlet 304 is provided above the horizontal air pipe 303. The air outlet 304 is fixedly connected to the horizontal air pipe 303. The air outlet 304 extends into the air cavities 107 of each support column bladder 101, the lower connecting bladder 103, and the corner bladder 104. Air enters the air cavity 107 through the air outlet 304.

[0027] A connecting hole 305 is provided between the upper connecting bladder 102 and the adjacent support column bladder 101. The connecting hole 305 connects the air cavities 107 of the upper connecting bladder 102 and the support column bladder 101. When too much air is filled in the support column bladder 101, the air pressure in the support column bladder 101 increases, and air is inflated into the upper connecting bladder 102 through the connecting hole 305.

[0028] A trampoline 2 is provided inside the inner circle of the airbag 1. The trampoline 2 is movably connected to the airbag 1, and the height of the trampoline 2 is lower than that of the airbag 1. The airbag 1 surrounds the trampoline 2 in the middle to protect the children on the trampoline 2 from being injured.

[0029] The trampoline 2 includes a frame 201 that serves to support the elastic surface layer 202. An elastic surface layer 202 is provided in the middle of the frame 201 to provide assistance for children to bounce and play. The periphery of the elastic surface layer 202 is fixedly connected to the inner circle of the frame 201. Four legs 203 are provided at the four corners of the lower side of the frame 201. The tops of the legs 203 are fixedly connected to the frame 201. The legs 203 lift the frame 201 and the elastic surface layer 202, so that children will not touch the ground and get injured when jumping on the elastic surface layer 202.

[0030] Move the trampoline 2 to a flat and suitable place, place the support legs 203 downward, unfold the safety airbag 1 so that the door opening 106 faces downward, and surround the trampoline 2. Pull out the plug 301, put the exhaust nozzle of the external air pump into the air nozzle 302, and turn on the air pump to inflate the air inflation pipeline 3. After the air enters the air nozzle 302, a part of it goes forward along the horizontal air pipe 303, and the other part is discharged from the air outlet 304 into the air cavity 107 to inflate the safety airbag 1. The air outlets 304 are provided in the support column airbag 101, the lower connecting airbag 103, and the corner airbag 104, and they can directly obtain air from the air inflation pipeline 3. However, there is no air outlet 304 in the upper connecting airbag 102. When too much air is filled in the support column airbag 101, the air pressure in the support column airbag 101 increases, and the air inflates into the upper connecting airbag 102 through the connecting hole 305. The air pressure in the support column airbag 101 begins to decrease, while the air pressure in the upper connecting airbag 102 begins to increase. When the air pressures in the support column airbag 101 and the upper connecting airbag 102 are equal, the air pump stops inflating the air inflation pipeline 3. Pull out the exhaust nozzle of the air pump, and plug the plug 301 into the air nozzle 302 to prevent the safety airbag 1 from leaking air, reducing its strength and losing its protective effect on the trampoline 2. The support column airbags 101 at the four corners are continuous from top to bottom, providing support for the entire safety airbag 1. The lower connecting airbag 103 connects the lower ends of the support column airbags 101 together, which not only increases the stability of the safety airbag 1 but also prevents children from falling. The upper connecting airbag 102 connects the upper ends of the support column airbags 101 together, pulling and supporting the support column airbags 101 so that they do not tip over. At the same time, it also protects children from jumping out of the top of the lower connecting airbag 103 and having an accident. The corner airbag 104 fixes the support column airbags 101 on adjacent sides together, increasing the connection area between the support column airbags 101 and improving the integrity of the safety airbag 1. Children enter the inner circle of the safety airbag 1 through the door opening 106 and climb onto the trampoline 2 to play. Parents can clearly see the situation of the children on the trampoline 2 through each observation window 105 and the door opening 106. If an accident occurs, they can provide help in time. When it is necessary to put away the safety airbag 1, pull out the plug 301. Under the action of gravity, the safety airbag 1 squeezes the air in the air cavity 107 out of the air nozzle 302. When the remaining air cannot be completely discharged, roll up the safety airbag 1 from a corner towards the air nozzle 302. When the safety airbag 1 is completely rolled up, the air in the air cavity 107 is also completely discharged, and it can be folded and stored.

[0031] The above are only the preferred embodiments of the present utility model and do not impose any formal restrictions on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to equivalent embodiments of equivalent changes within the scope of the technical solution of the present utility model by using the above-disclosed technical content.
