[0018] As attached Figure 1 , 2 As shown in Figure 3, this utility model of an easily adjustable inflatable sports knee brace includes an elastic sleeve 1, elastic support strips 2 disposed on both sides of the elastic sleeve 1, a patellar airbag 3 disposed on the front side of the elastic sleeve 1, an upper branch airbag disposed above the patellar airbag 3, a lower branch airbag disposed below the patellar airbag 3, and a strap assembly disposed on the elastic sleeve 1; an inflation port 4 is disposed above the patellar airbag 3, and the inflation port 4, the upper branch airbag, and the lower branch airbag are all fixed to the surface of the elastic sleeve 1; ventilation components are disposed above and below the popliteal fossa of the elastic sleeve 1. The inflation port is inflated by an air pump, which allows for fast inflation and allows users to inflate by hand. The support strength of the airbag is easily adjustable: when the inflation volume increases, the airbag expands, which can enhance the compression support force on the knee; when the deflation volume increases, the support force weakens, meeting the support intensity needs of different users, such as the personalized needs of light support for daily protection and heavy support for sports protection.

[0019] As attached Figure 1 As shown, the upper branch airbag of this utility model includes a left upper branch airbag 31 positioned obliquely above the left side of the patellar airbag 3 and a right upper branch airbag 32 positioned obliquely above the right side of the patellar airbag 3. A main airbag 35 is positioned in the middle of the upper part of the patellar airbag 3, and an inflation port 4 is installed on the top of the main airbag 35. The lower branch airbag includes a left lower branch airbag 33 positioned obliquely below the left side of the patellar airbag 3 and a right lower branch airbag 34 positioned obliquely below the right side of the patellar airbag 3. The left upper branch airbag 31 and The upper right branch airbag 32 is symmetrically arranged with respect to the midline of the patellar airbag 3; the lower left branch airbag 33 and the lower right branch airbag 34 are symmetrically arranged with respect to the midline of the patellar airbag 3; the upper left branch airbag 31, the upper right branch airbag 32 and the main airbag 35 are all connected to the patellar airbag 3; the lower left branch airbag 33 and the lower right branch airbag 34 are connected to the patellar airbag 3, and after inflation, they prevent lateral twisting of the knee; a patellar protective pad 8 is set in the middle of the patellar airbag 3 to protect the patella from impacts. The elastic sleeve 1 is made of composite elastic woven fabric. When the patellar airbag 3, the upper branch airbag and the lower branch airbag are inflated, the composite elastic woven fabric of the elastic sleeve 1 can stretch synchronously with the expansion of the airbag. The densely woven area restricts excessive expansion to maintain basic wrapping. When the airbag is deflated and shrinks, the elastic recoil of the densely woven area can help the airbag fit the knee and prevent the airbag folds from shifting.

[0020] The upper left branch airbag 31 and the patellar airbag 3 are connected by an upper left narrow bladder 36, and the upper right branch airbag 32 and the patellar airbag 3 are connected by an upper right narrow bladder 37; the lower left branch airbag 33 and the patellar airbag 3 are connected by a lower left narrow bladder 38, and the lower right branch airbag 34 and the patellar airbag 3 are connected by a lower right narrow bladder 39; the upper left narrow bladder 36, the upper right narrow bladder 37, the lower left narrow bladder 38, and the lower right narrow bladder 39 are all fixedly connected to the elastic sleeve 1. During inflation, the airflow speed is controlled to avoid the airflow directly hitting the airbag and causing local high pressure, thus achieving slow-release inflation.

[0021] As attached Figure 2 , 3 As shown in Figure 4, the strap assembly of this utility model includes an upper strap and a lower strap 7. The upper strap includes a left fixing loop 51 installed between the upper part of the left upper branch airbag 31 and the upper part of the main airbag 35, a right fixing loop 52 installed between the upper part of the right upper branch airbag 32 and the upper part of the main airbag 35, a left elastic strap 53 installed on the left fixing loop 51, and a right elastic strap 54 installed on the right fixing loop 52. The ends of the left elastic strap 53, which presses backward on the upper part of the left upper branch airbag 31, and the right elastic strap 54, which presses backward on the upper part of the right upper branch airbag 32, are on the rear side of the elastic sleeve 1 and are attached by hook and loop fasteners. The left fixing loop 51 is inclined to the lower right, and the right fixing loop 52 is inclined to the lower left. The lower strap is installed on the lower rear side of the elastic sleeve 1, and the two movable ends of the lower strap are pressed under the lower left branch airbag 33 and the lower right branch airbag 34 respectively and are attached by hook and loop fasteners.

[0022] The left elastic strap 53 and the right elastic strap 54 are fastened together to fix the elastic sleeve 1 and prevent the elastic sleeve 1 from moving upward. This can accommodate different leg circumferences of different wearers. The lower strap is fastened together to prevent the elastic sleeve 1 from moving downward, distribute pressure, and enhance the protective effect. The combination of the upper strap and the lower strap 7 can keep the knee brace in a stable position.

[0023] As attached Figure 2 , 3 As shown, the breathable component of this utility model includes a mesh breathable knitted fabric 61 and a lower mesh breathable knitted fabric 62 disposed on the rear side of the elastic sleeve 1; the mesh breathable knitted fabric 61 is located above the popliteal fossa, and the lower mesh breathable knitted fabric 62 is located below the popliteal fossa. This gradually reduces and distributes the load on the knee, improves the moisture absorption and breathability of this area, thereby effectively inhibiting sweat accumulation and providing comfortable breathability.
