Description

Technical Field

[0001] This invention belongs to the field of training equipment technology, and in particular relates to a stretching device for competitive aerobics training. Background Technology

[0002] Aerobics is a popular and widely enjoyed sport that combines gymnastics, dance, music, fitness, and entertainment. As an aerobic exercise, it primarily improves cardiovascular function and effectively strengthens the body. Before aerobics training, participants typically perform stretching exercises, usually using stretching devices to stretch their legs and improve flexibility.

[0003] The existing stretching device is equipped with a second sleeve, an arc plate, a rotating handle, and a spring. When in use, the second sleeve, in conjunction with the arc plate, can push the exerciser's legs to achieve leg stretching training. At the same time, the rotating handle, in conjunction with the spring, can perform strength training on the exerciser's arms.

[0004] While existing stretching devices can stretch the legs and strengthen the arms of trainees, in actual use, the trainee pulls the rotating handle, which causes the second sleeve and the curved plate to rotate. This means that while strengthening the arms, the trainee's legs are stretched and open at the hips. However, when pulling the rotating handle, the trainee's upper body tends to lean away from the legs, and when opening the hips, most trainees' upper body tends to lean towards the legs. Therefore, existing stretching devices have certain limitations in practical use, especially for beginners, as they cannot effectively stretch the legs.

[0005] Therefore, in view of the above situation, there is an urgent need to develop a training stretching device for competitive aerobics in order to overcome the shortcomings in current practical applications. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a training stretching device for competitive aerobics to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A competitive aerobics training stretching device includes a base, one end of which is fixed to a seat, and two sets of rotating seats are rotatably mounted on the base near the seat. It also includes:

[0009] The mounting base is provided in two sets. One end of each set of mounting bases is movably mounted on two sets of rotating seats via an adjustment component. The bottom of the mounting base is equipped with a sliding component that cooperates with the arc-shaped sliding groove on the base. There are multiple sets of arc-shaped sliding grooves, and the diameters of the multiple sets of arc-shaped sliding grooves are different.

[0010] The driving mechanism includes a sliding seat, a connecting seat, a first rotating component, a second rotating component, and a rotating shaft. The sliding seat is slidably disposed in a mounting groove opened on the mounting seat. A foot pedal is rotatably mounted on one side of the sliding seat through the mounting component. A foot pedal cavity is opened on the side of the foot pedal near the seat, and straps are distributed on the foot pedal.

[0011] The other side of the sliding seat is fixed with a connecting seat that is movably connected to one end of the first rotating member. The other end of the first rotating member is connected to the rotating shaft through the second rotating member. One end of the rotating shaft passes through the mounting seat and is connected to the resistance mechanism provided at the bottom of the mounting seat.

[0012] The resistance mechanism includes a fixing component, a rotating assembly, a guide seat, and a resistance component. The fixing component is fixed to the bottom of the mounting base. A rotating assembly connected to a rotating shaft is mounted on the fixing component. A guide seat is mounted on the rotating assembly. A resistance component that moves and abuts against the fixing component is installed inside the guide seat. Both the fixing component and the resistance component are block structures made of a material with good friction.

[0013] The user secures their feet in the pedal cavity with straps. Based on the user's leg length, the adjustment component adjusts the distance between the pedal and the seat via the mounting bracket. At this time, the sliding component is located in the arc-shaped groove at the farthest side away from the seat.

[0014] The user moves the sliding seat back and forth in the mounting slot by stepping on the pedal. The sliding seat moves the connecting seat back and forth. The connecting seat drives the rotating shaft to rotate through the first rotating component and the second rotating component. The rotating shaft drives the rotating component to rotate. The rotating component drives the resistance component to rotate through the guide seat. The resistance component applies a certain resistance to the drive mechanism by cooperating with the fixed component. The drive mechanism stretches the user's leg muscles by cooperating with the resistance mechanism.

[0015] The user rotates the sliding seat by stepping on the pedal, which in turn causes the mounting seat to rotate on the rotating seat. The mounting seat then causes the sliding component to slide within the arc-shaped groove of the corresponding diameter. The mounting seat, in conjunction with the sliding component, enables the user to perform hip-opening and stretching exercises on their legs.

[0016] As a further technical solution of the present invention, a guide roller is fixed in the mounting groove, the guide roller is slidably engaged with the sliding seat, and an elastic element is installed on the guide roller. The two ends of the elastic element are respectively movably connected to the inner wall of the mounting groove and one side of the sliding seat.

[0017] As a further technical solution of the present invention, the rotating assembly includes a third rotating component, a connecting shaft, and a fourth rotating component. The third rotating component is distributed at the bottom of the fixed component. There are three sets of the third rotating component. One end of each of the three sets of the third rotating component is fixedly connected to the fourth rotating component through the connecting shaft, and the other end of one set of the third rotating component is connected to the rotating shaft. A guide seat is fixed in the middle of the fourth rotating component.

[0018] As a further technical solution of the present invention, the sliding assembly includes a mounting roller and a sliding member. One end of the mounting roller is fixed to the bottom of the mounting base, and the other end of the mounting roller is equipped with a sliding member that is slidably installed in an arc-shaped groove. The outer diameter of the sliding member is smaller than the width of the arc-shaped groove.

[0019] As a further technical solution of the present invention, the adjustment component includes a second driving member, a transmission module and a second screw. The second driving member and the second screw are both installed in the rotating seat. The output end of the second driving member is connected to one end of the second screw through the transmission module, and the other end of the second screw is threaded into the mounting seat.

[0020] As a further technical solution of the present invention, the resistance mechanism further includes an adjustment component. One end of the adjustment component is mounted on the fourth rotating member, and the other end of the adjustment component extends into the guide seat through a guide groove opened on the side wall of the guide seat. The end of the adjustment component located on the guide seat is fixedly connected to the top of the resistance member.

[0021] As a further technical solution of the present invention, the adjustment assembly includes a first driving member, a first gear, a second gear, a first screw, a moving member, and a connecting member. The first driving member is fixed on a fourth rotating member. The output end of the first driving member is equipped with a first gear that meshes with the second gear. The second gear is fixed on the first screw. The two ends of the first screw are respectively movably mounted on the fourth rotating member and the guide seat. A moving member is screwed onto the first screw. One end of the moving member passes through a guide groove and extends into the guide seat. The end of the moving member located in the guide seat is connected to the connecting member. One end of the connecting member is fixedly connected to the top of the resistance member.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] The user secures their feet to the pedal cavity with straps. Based on the user's leg length, the second drive unit drives the second screw to rotate through the transmission module. The second screw rotates and moves the mounting seat on the rotating seat, thereby adjusting the distance between the pedal and the seat. At this time, the sliding component is located at the outermost edge of the arc-shaped groove away from the seat, making it convenient for the user to stretch and train their leg muscles.

[0024] The user moves the sliding seat back and forth in the mounting slot by stepping on the pedal. The sliding seat moves the connecting seat back and forth. The connecting seat drives the rotating shaft to rotate through the first and second rotating parts. The rotating shaft drives a set of third rotating parts to rotate. The three sets of third rotating parts drive the fourth rotating part to rotate through the connecting shaft. The fourth rotating part drives the resistance part to rotate through the guide seat. The rotating resistance part generates a certain resistance. The generated resistance is fed back to the sliding seat and the pedal, so that the user can stretch the leg muscles when stepping on the pedal, enriching the training function of the device and improving the practicality of the stretching device.

[0025] The user straightens their legs and rotates the sliding seat by stepping on the pedal. The sliding seat causes the mounting seat to rotate on the rotating seat, which in turn causes the mounting roller to rotate. The mounting roller causes the sliding component to slide in the arc-shaped groove of the corresponding diameter, thereby enabling the user to perform hip-opening and stretching exercises. During the hip-opening and stretching exercises, the user's upper body can move freely, making it convenient for novice users to perform leg stretching exercises.
