Description

Athlete knee joint limiter

Technical Field

The utility model relates to a knee joint limiter for athletes.

Background

With the development of society, sports is more and more emphasized. In sports, such as the dribbling action of basketball, the interval between two knees and the bending angle of the knees need to be regulated, and the regulated sports action can not only reduce the probability of being suffered in the sports process, but also improve the sports technology, so that the sports action is beautiful. The normative movements should be fostered from childhood and continuously develop muscle memory during repetitive training, so most parents choose to send their children to the coaching class of professional teachers for training, but the training teachers can only correct their mistakes at intervals and cannot continue to be effectively supervised.

For training of the knee, it can be assisted by using a knee stopper, but most of the commercially available knee stoppers are used in medical fields, such as chinese patent No.: 201721553104.0 discloses a knee joint traction angle adjusting device, which comprises a thigh supporting frame and a shank supporting frame, wherein, thigh connecting plates can be detachably connected on the two sides of the end part of the thigh supporting frame, a bolt circular plate is arranged at the end part of the thigh connecting plate, shank connecting plates can be detachably connected on the two sides of the end part of the shank supporting frame, a stop circular plate is arranged at the end part of the shank connecting plate, the bolt circular plate is rotationally matched with the stop circular plate through a connecting shaft, the stop circular plate is positioned at the inner side, the diameter of the stop circular plate is 1.1 times of that of the bolt circular plate, a storage box is welded at one side of the bolt circular plate, a limit screw pin is contained in the storage box, a 120-degree screw hole, a 90-degree screw hole, a 60-degree screw hole and a 45-degree screw hole are arranged at the other side of the bolt circular plate, the thigh supporting frame and the shank supporting frame are respectively provided with a 90-degree stop block, a 60-degree stop block and a 45-degree stop block, thread gluing belt burr surfaces can be detachably connected to one side positions of the thigh supporting frame and the shank supporting frame, thread gluing belt soft burr surfaces are respectively attached to the other side positions of the thigh supporting frame and the shank supporting frame, and magnet cloth pieces are arranged on the thread gluing belt burr surfaces in a penetrating mode. When the knee joint traction angle adjusting device is used, thighs of a wounded are protected by a thigh supporting frame, shanks of the wounded are protected by a shank supporting frame, the thighs and the shanks are respectively matched with the thigh supporting frame and the shank supporting frame, a sticky buckle barbed hair surface is tensioned to stick the sticky buckle barbed hair surface to a sticky buckle soft hair surface, then the fixing of the thigh supporting frame and the shank supporting frame is completed, a bolt circular plate and a block circular plate are rotationally matched through a connecting shaft, a limit screw pin is placed in a storage box, the limit screw pin is taken out of the storage box when the knee joint traction angle adjusting device is needed to be used, then the limit screw pin is matched with one of a 120-degree screw hole, a 90-degree screw hole, a 60-degree screw hole and a 45-degree screw hole, the 120-degree screw hole, the 90-degree screw hole, the 60-degree screw hole and the 45-degree screw hole are respectively matched with a 120-degree block, a 90-degree block, a 60-degree block and a 45-degree block, when the limit screw pin is screwed, the fixation is formed, and the bending angle of the rehabilitation exercise of the knee joint can be gradually increased along with the continuous recovery of the injury of the knee joint; however, the knee joint angle adjusting device reduces the bearing capacity of the knee by adjusting the bending angle of a single knee and supporting the knee, and cannot limit the spreading angle of two knees of a player.

Therefore, a knee limiter which is suitable for limiting two knees of an athlete in training and enables the athlete to continuously form muscle memory in repeated training so as to standardize the motion of the athlete needs to be developed.
