[0002] Health care refers to a series of scientific methods and measures to maintain and enhance physical health, prevent diseases, and improve the quality of life. Through scientific health care methods, physical fitness can be effectively improved. Generally, the legs are trained by a leg trainer. A leg trainer is a fitness equipment used to exercise leg muscles, usually designed to enhance leg strength, improve muscle endurance, and promote blood circulation.

[0003] When the current leg trainer for health care is in use, since the size of the pedal of the stepper is not easy to adjust, it is not easy to meet the usage requirements of most users, and it is easy to cause detachment and sliding during training, thus reducing the practicability and training effect. During the use of the leg trainer, due to the user's force, it is easy to cause the stepper to move abnormally and the device to be damaged, affecting the user's training and the normal operation of the device, thus reducing the stability of the device and the user experience. Therefore, the technical personnel in this field provide a leg trainer for health care to solve the problems raised in the above background technique. Content of the Utility Model

Through the setting of the pedal device, it can be adjusted and clamped according to the different sizes of the user's feet, and it avoids the user's feet sliding and falling off due to poor stability during use, affecting leg training, thus improving the practicability and stability, and improving the training effect. Then, through the setting of the adsorption device, it avoids the stepper being stressed and causing damage and abnormal movement of the lead screw, affecting the normal operation of the trainer, thus improving the stability of the device and the user experience. Then, through the cooperation of the slider, the chute and the lead screw, it meets the movement adjustment of the stepper. Finally, through the cooperation of the cylinder and the support rod, it meets the lifting adjustment of the seat and can be adjusted and adapted according to the different heights of users, thus improving the universality and practicability of the trainer.

At the center of the upper end surface of the slider, a stepper is fixedly connected. At the centers of the front and rear end surfaces of the stepper, there are rotating rods. At the ends of the two rotating rods, there are pedal devices respectively. At one side near the center inside the base, there is a baffle. At the center of one side of the baffle, there is a rotating motor. At the output end of the rotating motor, there is a lead screw. At one side near the center of the lower inner wall of the base, there is an adsorption device. At one side near the center of the lower inner wall of the base, there is a cylinder. At the output end of the cylinder, a seat is fixedly connected. At the center of the front end surface of the seat, there is a controller.

Then, through the elasticity of the spring components, the L-shaped sliding blocks clamp the user's feet, satisfying the fixation of the feet.

[0009] Further, at the center near the front end of the upper end surface of the pedal main body, there is a restraint strap. At one end near the lower end surface of the restraint strap, there is a female velcro layer. At the center of the lower end surface of the pedal main body, there is a male velcro layer.

[0033] The slider 3 sequentially passes through the chute 2 and the upper end face of the base 1 and extends to the inside of the base 1, and is threadedly sleeved with the lead screw 9. One end of the lead screw 9 is rotatably connected to the inner side wall of the base 1 through a bearing.

The support rod 13 strengthens the stability of the seat 12, thus improving the safety of users. Then, the slider 3 drives the suction cup 1002 to move on the upper surface of the smooth plate 1004, preventing the suction cup 1002 from affecting the adsorption and fixation during movement. By starting the vacuum pump 1001, a negative pressure is generated between the suction cup 1002 and the smooth plate 1004, causing the suction cup 1002 to tightly adsorb on the smooth plate 1004, preventing the stepper 4 from exerting force and causing damage and abnormal movement of the lead screw 9, which affects user training and the normal operation of the equipment, thereby improving the stability of the equipment and the user experience.
