Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary equipment for running sports, and in particular to a hamstring mobilization device for running sports. Background Art

[0002] Athletes will stretch their hamstrings before running. If the hamstrings are not fully active, cramps or poor running performance may occur easily during running. When stretching the hamstrings, the legs are usually straightened, the forefoot is raised, and the forefoot is moved by hand for stretching. This posture is not easy to maintain body balance and may easily lead to falling. If two people cooperate in the activity, they need to sit on the ground and stretch each other's hamstrings, but the effect of stretching the hamstrings in a sitting position is not as good as stretching the hamstrings in a standing position. Summary of the invention

[0003] In order to overcome the deficiencies in the background technology, the present invention discloses a hamstring exercise device for running exercise, which can effectively exercise the hamstrings.

The pedaling mechanism 2 can lift the toes, and can stretch the hamstrings of the foot while activating the hamstrings.

[0018] The main frame 1 includes a base plate 101, a support plate 102 and a rotating rod 103. Two support plates 102 are fixedly connected to the base plate 101. The rotating rod 103 is rotatably connected between the two support plates 102, and the rotating rod 103 is connected to the front sole placement end of the pedaling mechanism 2. The supporting mechanism 3 is installed on the base plate 101.

[0019] The bottom plate 101 is provided with two sliding grooves, and the supporting mechanisms 3 are installed in the sliding grooves.

[0020] The pedaling mechanism 2 includes a pedal board 201, a heel limiting plate 202, a toe pushing plate 203, a screw rod 204, a connecting plate 205 and a threaded connecting block 206. There are two connecting plates 205. Both connecting plates 205 are located on the rotating rod 103 and are fixedly connected. One end of the connecting plate 205 is fixedly connected to the pedal board 201. The pedal board 201 is rotatably connected to the screw rod 204, and the screw rod 204 is threadedly connected to the threaded connecting block 206. The toe pushing plate 203 is fixedly connected to the threaded connecting block 206. The pedal board 201 is fixedly connected to the heel limiting plate 202.

[0021] A groove is provided in the middle of the pedal 201 , and a screw rod 204 is rotatably connected in the groove. The adjustment end of the screw rod 204 passes through the rotating rod 103 and is located outside the rotating rod 103 .

[0022] A rotation groove is provided on one end of the pedal 201 away from the rotating rod 103, and a supporting end of the supporting mechanism 3 is installed in the rotation groove.

[0023] One end of the toe pushing plate 203 close to the rotating rod 103 has a certain curvature, and the toes of the athlete are lifted up by the curvature of the toe pushing plate 203 .

[0024] One end of the toe push plate 203 away from the rotating rod 103 is an inclined surface, and the lowest end of the inclined surface of the toe push plate 203 contacts the upper surface of the pedal 201 .

[0025] The supporting mechanism 3 comprises a sliding rod 301, a sliding plate 302, a telescopic plate 303 and a return spring 304. The sliding rod 301 is divided into two groups, and each group of sliding rods 301 has two sliding rods. The two groups of sliding rods 301 are respectively located in two sliding grooves and fixedly connected, and a return spring 304 is sleeved on the sliding rod 301. One end of the return spring 304 is fixedly connected to the groove wall of the sliding groove, and the other end of the return spring 304 is fixedly connected to the sliding plate 302.

[0027] The hamstring activity device for running, when in use, the athlete rotates the screw 204 according to his own situation, and the screw 204 drives the toe push plate 203 to move through the threaded connection block 206, so that the toe push plate 203 is more closely fitted to the toe part of the athlete. When the athlete steps on the pedal 201, the heel part of the athlete fits the heel limit plate 202, and the toe part is aligned with the toe push plate 203, so that the toe part is in a tilted state. The staff steps on the pedal 201, and the pedal 201 moves in a circle along the rotating rod 103, and the sole of the foot is in a tilted state when the pedal 201 is stepped on. After the athlete unloads the force, the retractable plate 303 is pushed to reset through the reset spring 304, and the pedal 201 is driven to reset through the retractable plate 303. Through repeated stepping, the sole of the foot can effectively exercise the hamstrings when it is tilted. While stepping on, the athlete's foot will be completely close to the pedal 201, and the toes are pushed to tilt up through the toe pushing plate 203. The tilting of the toes can stretch the tendons of the foot.
