The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0022] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] The utility model embodiment provides an OA knee brace, such as Figure 1-4 As shown, it includes a thigh protector plate 1, a connector 2 and a calf protector plate 3, the connector 2 is located between the thigh protector plate 1 and the calf protector plate 3, the bottom of the thigh protector plate 1 and the top of the calf protector plate 3 are both provided with a rotating head 4, the inside of the rotating head 4 is rotatably connected to a turbine 5, a hexagonal hole 6 is provided at the top center of the turbine 5, a worm 7 is rotatably connected to the inside of the rotating head 4 near the turbine 5, and a fixed head 8 is provided at the top and bottom of the connector 2, and the rotating head 4 and the fixed head 8 match Buckles 10 are provided on one side outer wall of the thigh protector plate 1 and the calf protector plate 3. There are four buckles 10 in total, and the four buckles 10 are respectively arranged on the outer side walls of the thigh protector plate 1 and the calf protector plate 3 in groups of two. A limb strap 9 is provided at one end of the buckle 10. The limb strap 9 is made of breathable and non-slip fabric. An extension strap 11 is provided on the end of the limb strap 9 away from the buckle 10. Extension strap threading grooves 12 are provided on the other side outer walls of the thigh protector plate 1 and the calf protector plate 3.

[0024] It should be noted that, since the existing knee brace can only adjust the angle between the braces when adjusting the angle, and due to the different leg shapes and thicknesses of different patients, the brace is difficult to fit on the outside of the patient's leg, and the brace is difficult to turn inward or outward, resulting in poor fitting of the knee brace, and thus reduced support effect on the leg. In this embodiment, after the hexagonal wrench is inserted into the hexagonal hole 6, the turbine 5 is rotated, and the worm 7 can drive the fixing head 8 to rotate through the meshing transmission, so that when the connector 2 is in a fixed state, the thigh brace plate 1 and the calf brace plate 3 can be turned inward or outward, so that the thigh brace plate 1 and the calf brace plate 3 can fully fit on the legs of different patients, and the limb strap 9 can be used to fix the knee brace on the patient's leg, and the patient's knee is effectively supported to reduce the pain caused by knee injuries.

[0025] Specifically, in this embodiment, this scheme mainly includes a turbine 5 and a worm 7. When the kneepad is worn, the angles of the thigh guard plate 1 and the calf guard plate 3 and the connector 2 are adjusted according to the patient's leg shape and thickness, the connector 2 is pressed against the side of the knee, the hexagonal wrench is inserted into the hexagonal hole 6 and rotated clockwise or counterclockwise, and the turbine 5 is rotated to drive the worm 7 to rotate through the meshing transmission. The kinetic energy generated by the worm 7 during the rotation process causes the thigh guard plate 1 or the calf guard plate 3 to flip toward the inside or outside of the leg, thereby adjusting the angles of the thigh guard plate 1 and the calf guard plate 3 and the connector 2, so that the thigh guard plate 1 and the calf guard plate 3 are pressed against the outside of the leg, ensuring that the kneepad is worn tightly, the limb strap 9 is wrapped around the leg, and the extension strap 11 at one end of the limb strap 9 is inserted into the extension strap groove 12, so as to achieve the binding of the extension strap groove 12, ensuring that the kneepad is worn tightly and prevent it from falling off.

[0026] In a further preferred embodiment of the present invention, Figure 1 and Figure 3 As shown, the turbine 5 and the worm 7 are meshed and connected with each other, and the turbine 5 and the worm 7 transmit transmission to each other, and both ends of the worm 7 are fixedly connected to the fixed head 8.

[0027] In this embodiment, the meshing transmission can be used to rotate the turbine 5 to drive the worm 7 to rotate, thereby changing the direction of the rotational force, thereby achieving inversion or eversion of the thigh guard plate 1 and the calf guard plate 3.

[0028] In a further preferred embodiment of the present invention, Figure 1 As shown, the extension strap 11 passes through the extension strap slot 12 and is wound around.

[0029] In this embodiment, one end of the extension strap 11 can be fixed by the extension strap groove 12, and the knee is tied to the leg to achieve the wearing of the knee pad.
