[0002] The knee joint is an important joint in the human body, bearing a large load and prone to injuries and diseases such as osteoarthritis and meniscus injury. Patients suffer from knee pain and limited movement, which seriously affects their quality of life. Traditional treatment methods are limited, and drug treatment can only relieve symptoms but cannot fundamentally solve the load problem; surgical treatment is risky, traumatic, and takes a long time to recover. Some patients cannot tolerate it. Orthotic braces can assist in treatment, reduce the load on the knee joint, relieve pain, and promote recovery.

[0003] However, existing braces have problems such as poor fit, low comfort, and poor load-reducing effect, which limit their application.

[0013] The present invention provides a knee orthotic brace that can reduce the load on the knee joint. It has the following beneficial effects: 1. The knee orthosis brace which can reduce the load on the knee joint is provided with a second fixed block, which drives the pull wire to move, and the movement of the pull wire drives the fixed seat to move, and the movement of the fixed seat drives the fixed frame to rotate along the rotating base, and the rotation of the fixed frame drives the spring sheet to move, and the movement of the spring sheet drives the fixed plate to move, and the movement of the fixed plate drives the flexible convex pad to move, and the movement of the flexible convex pad strengthens the positioning and fixation of the user's waist, thereby enhancing the stability during installation, the spring sheet is used to provide elasticity so that the flexible convex pad fits tightly against the user's waist, the pull wire limits the waist, thereby achieving stable installation, the sliding wire groove is used to slide and limit the pull wire, the stepped hole is used to limit the first fixed block, the limit plate limits the fixed seat, and the arc guide plate is used to support the pull wire when it is changing direction, thereby avoiding the pull wire from breaking due to side contact with the right angle during stretching.

[0014] 2. The knee joint orthosis brace which can reduce the load on the knee joint is provided with a twisting handle, which drives the winding frame to rotate, and the rotation of the twisting handle drives the sliding ring to rotate, and the rotation of the sliding ring drives the brake rack to move, and the movement of the brake rack engages with the brake block to brake, thereby performing a single brake on the sliding ring, so that the pull wire moves along the winding frame to tighten the pull wire, and the pull wire moves along the inner wall of the wire groove, thereby driving the wire groove to rotate along the side of the fixed connecting plate, thereby driving the rotating plate to be close to the user's waist, and pulling the pull wire to tighten the rotating plate, so that the rotating plate is tightly connected to the user's waist. It is fixed with a stick. When it needs to be disassembled, the twist handle is pushed manually. The twist handle drives the sliding ring to slide radially along the side of the rotating seat, so that the brake rack is disengaged from the brake block, thereby stopping the braking of the sliding ring, and causing the sliding ring to rotate in the opposite direction along the side of the rotating seat to release it. When the sliding ring slides along the rotating seat, the sliding ring compresses the spring rod, so that the elastic force acts on the side of the sliding ring, thereby pushing the sliding ring to drive the brake rack to re-engage with the brake block, thereby restoring the one-way braking, thereby facilitating operation and increasing durability and ease of operation compared to traditional fixing methods.

[0015] 3. The knee orthotic brace that can reduce the load on the knee joint is provided with a ventilation duct. Air moves through the interior of the ventilation duct and is released along the ventilation duct through the air outlet, so that the air moves along the air outlet, thereby dissipating heat to the user's crotch, thereby avoiding the problems of heat accumulation and sweating caused by long-term use.

The cooperation between the arc-shaped rotating hole and the sliding bracket enables the adjustment rod to have a certain rotation angle, thereby increasing the degree of freedom of the adjustment rod, thereby increasing multi-angle support during use, and facilitating use in different situations.

[0017] 5. The knee orthosis brace that can reduce the load on the knee joint is provided with an elastic frame. The foot moves through the interior of the elastic frame, so that the area near the knee joint is close to the interior of the elastic frame. The fixing strap is manually pulled to cooperate with the fixing rod to fix it, thereby pulling the elastic frame to bend, thereby driving the square airbag to closely contact the side of the knee, thereby supporting the side of the knee. Gas is introduced through a first one-way valve and the air pressure inside the square airbag is maintained to support the side of the knee. When the user walks, the distance between the elastic frame and the support base changes, thereby driving the support base to drive the pneumatic telescopic rod to compress, thereby driving gas along the pipeline to enter the interior of the first one-way valve, thereby pressurizing the square airbag during walking, thereby pressurizing and fixing the side of the knee. At the same time, the interior of the pneumatic telescopic rod and the interior of the first one-way valve are pressurized through the air guide tube. The process of increasing air pressure inside the fixed end of the pneumatic telescopic rod prolongs the contact time with the ground and the compression process, thereby reducing the load on the knee and reducing the pressure on the knee joint.

[0035] The user's foot is fixed by the cooperation between the guide of the front positioning shell 5052 and the rear positioning plate 5053 and the support base plate 5051, and the foot moves through the inside of the elastic frame 5041, so that the area near the knee joint is close to the inside of the elastic frame 5041, and the fixing belt 5045 is manually pulled to cooperate with the fixing rod 5046 to fix it, thereby pulling the elastic frame 5041 to bend and drive the square air bag 5042 to fit closely to the side of the knee, thereby supporting the side of the knee, and introducing gas through the first one-way valve 5044 and maintaining the air pressure inside the square air bag 5042, thereby supporting the side of the knee. When walking, the distance between the elastic frame 5041 and the support base 5051 changes, thereby driving the support base 5051 to compress the pneumatic telescopic rod 5054, thereby driving the gas along the pipeline into the first one-way valve 5044, thereby pressurizing the square airbag 5042 when walking, thereby pressurizing and supporting the side of the knee, and at the same time, the interior of the pneumatic telescopic rod 5054 and the interior of the first one-way valve 5044 are pressurized through the air guide tube 507. The process of increasing the internal air pressure of the fixed end of the pneumatic telescopic rod 5054 extends the contact time with the ground and the compression process, thereby reducing the load on the knee, thereby reducing the pressure on the knee joint.
