Description

Technical Field

[0001] The utility model relates to the technical field of sports training, in particular to an air resistance type leg swing training device. Background Art

[0002] The leg swing trainer is a training device for legs and hips. It can perform multifunctional training of hip flexion, extension, adduction and abduction, effectively training the hip joint, reducing muscle relaxation, stabilizing muscle strength, improving posterior group explosive power and leg frequency, so that athletes can achieve the desired training effect during training.

[0003] At present, most of the existing leg swing training devices use hanging plates for weight distribution, but the hanging plate type equipment still has major disadvantages in use: first, the hanging plate type equipment occupies a large area, has requirements for the size of the use venue, and has poor versatility; second, the size of the resistance when the equipment is used depends on the weight of the hanging plate, and it is difficult for athletes to control it accurately when adjusting. If the resistance is too large, it cannot be used, and if the resistance is too small, the training purpose cannot be achieved, and the athlete can only try to adjust it back and forth; third, in order to achieve the training purpose during the use of the equipment, the resistance often needs to be increased so that the weight of the hanging plate is slightly greater than the strength of the leg. Under the action of the swing inertia, the swing force generated by the hanging plate is often higher than the weight of the hanging plate itself, which is bound to increase the load on the athlete's legs. In severe cases, it may cause leg strain. In addition, the swing force generated during the swing is unstable and uncontrolled, which undoubtedly further increases the risk of injury to the athlete.

[0034] Optionally, the support mechanism includes a support base plate 36 arranged on the front side of the base plate 1, and the support base plate 36 is connected to the base plate 1 through support legs 37 arranged on the left and right sides of its rear side wall, and support tubes 38 are vertically provided on the left and right sides of the front side wall of the support base plate 36, and a number of positioning holes 39 are respectively provided on the two support tubes 38 along their length directions. A foot pedal 40 is provided above the support base plate 36, and the foot pedal 40 is connected to the support tube 38 through positioning pins 41 arranged on the left and right sides of its front side wall, and each positioning pin 41 is respectively inserted into one of the positioning holes 39 of the support tube 38 on the corresponding side.

[0035] When using this device, an athlete can stand on the footrest 40 and adjust the height of the foam pad 34. Loosening the locking bolt 35 allows the adjustment tube 32 to move on the boom tube 6, thereby adjusting the height of the foam pad 34. The training position can also be adjusted by adjusting the height of the footrest 40. This can be achieved by engaging the positioning pin 41 of the footrest 40 into the positioning hole 39 at different heights. Athletes can simultaneously perform hip flexion, extension, adduction, and abduction. Grasping the handle 29 on the handlebar tube 28 with both hands or one hand, and resting the leg against the foam pad 34, the athlete applies force, pushing the foam pad 34 and the boom tube 6 to rotate along the drive shaft 5, which in turn drives the upper cable drum 8 in radial rotation. The upper cable drum 8 pulls the rope 21 through the upper clamping seat 19, which in turn rotates the lower cable drum 13 through the pulley 10 and lower clamping seat 20. The lower cable drum 13, in turn, is withdrawn by the piston rod of the cylinder 17 pulled outward by the L-shaped support arm 15. Under the action of the air supply mechanism, the air cylinder 17 resists the pulling force of the L-shaped support arm 15, forming an air block. Athletes can control the activation of the compressor 22 through the control device 24 according to their needs. The compressor 22 presses gas into the air supply tank 23 and supplies it to the air cylinder 17 through a pipeline. It has a reasonable structural design, a small footprint, and strong versatility. The air block structure ensures a stable and controllable swing force, effectively controlling the load on the athlete's legs and avoiding the risk of leg strain. The air block's resistance is controllable and can be adjusted according to the athlete's habits to keep the resistance within the athlete's strength tolerance. This not only achieves the training purpose, but also avoids the risk of injury caused by excessive resistance, solving the problems existing in the prior art.
