[0056] Reference Figures 1 to 13 , an inflatable trampoline, comprising:

[0057] An inflatable frame 100, the inflatable frame 100 comprising a plurality of first sheets 110 and a plurality of second sheets 120, wherein a fabric layer 112 is provided in the first sheet 110, two second sheets 120 are respectively welded to two edges of the first sheet 110, two adjacent second sheets 120 are welded to each other, the first sheet 110 and the second sheet 120 form the inflatable frame 100, and an inflatable cavity 101 is provided in the inflatable frame 100;

[0058] A connecting sheet 200, the edge of which is welded to the upper surface of the inflatable frame 100, and an opening 201 is provided in the middle of the connecting sheet 200;

[0059] The elastic component 300 is located in the opening 201 , and the elastic component 300 is connected to the connecting sheet 200 via a plurality of first connecting members 210 .

[0060] Through the arrangement of the above structure, when in use, gas is injected into the inflatable cavity 101 to inflate and harden the inflatable frame 100, thereby providing a stable supporting force; when the user sits, lies, walks or jumps on the elastic component 300, the elastic force of the elastic component 300 can effectively drive the user to jump up or support the user, and the force exerted on the elastic component 300 is uniformly applied to the inflatable frame 100 through the connecting sheet 200, so that the inflatable frame 100 can provide a stable support; and, since the inflatable frame 100 has the inflatable cavity 101, its density is low, and it can float on the water surface under the action of buoyancy, thereby increasing the adaptability and fun of the product; wherein, the first sheet 110 and the second sheet 120 are both made of PVC The first sheet 110 is provided with a fabric layer 112, which can provide support to prevent the first sheet 110 from being deformed by force and maintain the stability of the product. It can also enhance the wear resistance, tear resistance and weather resistance of the product and effectively extend the service life of the product. However, since the fabric layer 112 is provided in the first sheet 110, compared with the second sheet 120 made of pure PVC material, the first sheet 110 has poor welding properties. Directly welding two first sheets 110 may easily cause fractures at the connection. Connecting two adjacent first sheets 110 through the second sheet 120 can improve the stability of the connection and ensure the air tightness and structural stability of the product.

[0061] In this embodiment, the first welding area 111 is set at both edges of the first sheet 110, and the second welding area 121 is set at the edge of the second sheet 120 near the first sheet 110. The first welding area 111 and the second welding area 121 are stacked up and down and welded to each other. Through the above-mentioned structure, the first welding area 111 and the second welding area 121 are stacked up and down, which can increase the contact area between the two, and effectively prevent the first sheet 110 and the second sheet 120 from moving and deforming during the welding process, ensuring the stability of the connection, and then use a high-frequency plastic welding machine to weld the first welding area 111 and the second welding area 121 to ensure the stability of the product and effectively reduce the product from breaking or leaking at the connection between the first sheet 110 and the second sheet 120.

[0062] In this embodiment, the distance between the fabric layer 112 and the upper surface of the first sheet 110 is smaller than the distance between the fabric layer 112 and the lower surface of the first sheet 110, and the lower surface of the first welding zone 111 is attached to and welded to the upper surface of the second welding zone 121. Through the above-mentioned structure, since the distance between the fabric layer 112 and the upper surface of the first sheet 110 is smaller than the distance between the fabric layer 112 and the lower surface of the first sheet 110, the thickness of the PVC layer at the lower surface of the first sheet 110 is larger, and the lower surface of the first welding zone 111 is attached to and welded to the upper surface of the second welding zone 121, which can further ensure the stability of the connection between the first sheet 110 and the second sheet 120, and ensure the air tightness and service life of the product; at the same time, the distance between the fabric layer 112 and the upper surface of the first sheet 110 is smaller, and the fabric layer 112 is near the outer surface of the first sheet 110, which can further improve the wear resistance, tear resistance and weather resistance of the product.

Through the above-mentioned structure, when producing products, the third welding areas 122 of two adjacent second sheets 120 are aligned and extended outward, and then the two third welding areas 122 are welded using a high-frequency plastic welding machine to achieve the connection of two adjacent second sheets 120. Since the second sheet 120 is made of pure PVC material, the connection between the two adjacent second sheets 120 is stable, ensuring the air tightness of the product; and aligning the third welding areas 122 of two adjacent second sheets 120 and extending them outward can make it easier for the high-frequency plastic welding machine to act on the third welding area 122, reduce the difficulty of production, and improve production efficiency.

Preferably, a check device is also provided in the air flow channel 411, such as a one-way valve, a diaphragm, etc.

[0068] In this embodiment, the gas valve assembly 400 further includes a connecting belt 430, one end of which is connected to the valve body 410, and the other end of which is connected to the valve cover 420.
