Description

Technical Field

[0001] The utility model belongs to the technical field of training, in particular to a limb joint range of motion training device. Background Art

[0002] The major joints of the limbs refer to the important joints of the human body, mainly including the shoulder joint, elbow joint, knee joint, etc. At the same time, the joints can control the limbs, maintain the stability of the muscles, have the effects of transportation and conduction, and can make the limbs coordinated. Training the joints after human surgery can prevent complications such as aspiration pneumonia, urinary tract infection, thrombosis, muscle atrophy, osteoporosis, etc.

[0003] In the process of joint training, some training equipment is needed. When using traditional equipment, the arms and legs are usually trained separately, which increases the cost and maintenance cost of the equipment. For this purpose, a limb joint range of motion trainer is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a limb joint range of motion training instrument, which can swing the second arm support through the setting of the second arm support, so that when the arm is trained, the second arm support can swing with the cooperation of the corrugated plate and the top rod, thereby improving the flexibility of use, increasing the training effect, and solving the existing technical problems.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] A limb joint range of motion training device comprises: a base, a reclining chair fixedly connected to the surface of the base, a skateboard slidably connected between two sides of the base, a mounting seat fixedly connected to the surface of the skateboard, a worm gear rotatably connected between the inner walls of two sides of the mounting seat, a rotating frame fixedly connected to both sides of the worm gear, and a foot pedal rotatably connected to one side of the rotating frame;

[0007] The surface of the base is fixedly connected to two guide rails, and a sliding seat is slidably connected to the guide rails. Both ends of the sliding seat are rotatably connected to the first support rod and the second support rod, and the second support rod is rotatably connected to the rotating frame. The bottom of the recliner is fixedly connected to a fixed block, and one side of the fixed block is rotatably connected to a penetrating driving shaft. Both ends of the driving shaft are fixedly connected to the first arm support, and the circumference of the driving shaft is fixedly connected to two swing arms, and the two swing arms are rotatably connected to the two first support rods respectively. The foot pedal is set to move synchronously with the first arm support, so that when training the limbs, the arms and legs can be trained at the same time, thereby increasing the linkage effect during training and reducing the cost of the equipment.

[0008] As a further solution of the present invention, a motor is fixedly connected to the surface of the skateboard, a worm is fixedly connected to one end of the motor output shaft, and the worm is meshed with the worm wheel.

[0009] As a further solution of the present invention, one side of the base is rotatably connected to a threaded rod, and the thread of the threaded rod passes through the skateboard. Rotating the threaded rod can adjust the position of the skateboard, thereby changing the leg posture for easy use.

[0010] As a further solution of the present invention, the bottom of the first arm support is rotatably connected to a penetrating installation shaft, the top of the installation shaft is fixedly connected to the second arm support, and a torsion spring is fixedly connected between the installation shaft and the first arm support.

[0011] As a further solution of the present invention, one side of the second arm support is fixedly connected to an arc-shaped top rod, one side of the top rod is rotatably connected to a top shaft, and the surface of the base is fixedly connected to a corrugated plate used in conjunction with the top shaft. The second arm support can be swung by the cooperation of the corrugated plate and the top rod when training the arm, thereby improving the flexibility of use and increasing the training effect.

[0012] As a further solution of the present invention, a protective sleeve for shielding the worm gear is fixedly connected to the top of the mounting seat.

[0013] As a further solution of the present invention, a plurality of supporting legs are fixedly connected to the bottom of the base.

[0014] As a further solution of the present invention, a protective plate is fixedly connected to the surface of the first arm support.

[0015] In the utility model, when in use, the person who needs training lies on the recliner, steps on the foot pedals with both feet, places both arms on the first arm support and the second arm support, and then starts the motor, the motor drives the worm gear to rotate through the worm, the worm gear drives the rotating frame to rotate, and the rotating frame drives the foot pedals to rotate, thereby training the legs. During the rotation process, the rotating frame also drives the second support rod to rotate, and the second support rod drives the sliding seat to move back and forth, and the sliding seat drives the swing arm and the drive shaft to reciprocate through the first support rod, and then drives the first arm support and the second arm support on both sides to swing through the drive shaft, thereby realizing arm training. When the first arm support and the second arm support swing, the second arm support drives the top rod to move, and the top rod drives the top shaft, and the top shaft cooperates with the corrugated plate to make the second arm support swing, and the second arm support forms a reciprocating motion under the cooperation of the torsion spring, thereby training the arms.

[0016] The embodiments of the present invention have the following beneficial effects:

[0017] In the utility model, the foot pedal and the first arm support are arranged to move synchronously, so that when training the limbs, the arms and legs can be trained at the same time, thereby increasing the linkage effect during training and reducing the cost of the equipment;

[0018] In the present invention, the second arm support is capable of swinging, so that when the arm is trained, the second arm support can swing in cooperation with the corrugated plate and the top rod, thereby improving the flexibility of use and increasing the training effect;

[0019] In the utility model, when training the limbs, the arms and legs can be trained at the same time, which increases the linkage effect during training and reduces the cost of the equipment. At the same time, the second arm support can swing under the cooperation of the corrugated plate and the top rod, which improves the flexibility of use and increases the training effect.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
