Description

A kind of rhythmic gymnastics flip training auxiliary device

technical field

The invention belongs to the field of sports training auxiliary devices, in particular to a rhythmic gymnastics turning training auxiliary device.

Background technique

"Gymnastics" in a broad sense is the general term for all gymnastics events. Gymnastics in the modern Olympic Games consists of three major items: competitive gymnastics, rhythmic gymnastics and trampoline. In addition, there are non-Olympic sports such as competitive aerobics and acrobatics. Flip is one of the essential training movements in all kinds of gymnastics. Flip is divided into different movements such as hand flip, spin flip, and rollover. Twist flip is one of gymnastic somersaults, which means that the human body flips along the horizontal axis for two weeks after flying At the same time, the compound somersault action of rotating the body around the vertical axis. According to the turning direction, it can be divided into forward rotation and back rotation; according to the human body posture, it can be divided into round body rotation, bent body rotation, and straight body rotation; It is very necessary to practice good rhythmic gymnastics performance. It is difficult for beginner gymnasts to overcome the dizziness caused by turning. Long-term training is required to adapt well. However, the physical strength of athletes is limited, and it is difficult to do a large amount of turning exercises in a short period of time.

The present invention is achieved through the following technical solutions:

An auxiliary device for rhythmic gymnastics flipping training, comprising a base, an annular track is arranged on the upper part of the base, the annular track and the base are fixedly connected by a bracket, the inner circle of the annular track cooperates with an arc-shaped first slider with its own power, and the top of the base The vertical rod is fixedly installed near the rear side. The front side of the vertical rod is provided with a horizontal shaft. The rear end of the horizontal shaft is movably linked with the vertical rod bearing. The horizontal shaft is coaxial with the circular track. There is a horizontal grab bar at the bottom of the front end, and a vertical connecting rod is fixedly installed in the middle of the top of the grab bar. The upper end of the connecting rod is movably connected with the side bearing of the horizontal shaft. A hydraulic rod is perpendicular to the inner concave surface of the first slider. The upper end of the first hydraulic rod is installed with a rotating shaft through a bearing. The rotating shaft is coaxial with the first hydraulic rod. The upper end of the rotating shaft is fixedly equipped with a pedal. The vertical rail is fixedly installed near the upper end on the front side, the second slider is installed on the vertical rail, the second hydraulic rod is fixedly installed on the front side of the lower end of the vertical rail, the upper end of the second hydraulic rod is fixedly connected with the lower end of the second slider, The front end of the block is fixedly installed with the third horizontal hydraulic rod, and the front end of the movable rod of the third hydraulic rod is fixedly installed with an arc rod, which is composed of a plurality of evenly distributed arc short rods, a plurality of fourth hydraulic rods, a plurality of The connection block is composed of connecting blocks, which are fixedly installed at the bottom of both ends of the arc-shaped short rods, and the two adjacent connecting blocks at the bottom of two adjacent arc-shaped short rods are hinged through the fourth hydraulic rod. The two adjacent ends of the first arc-shaped short rod are hingedly connected, the rear side of the uppermost arc-shaped short rod is fixedly connected with the front end of the movable rod of the third hydraulic rod, and the front side of the arc-shaped short rod is fixed. The short arc rack is installed, the teeth of the short arc rack are ahead, the short arc rack has the same length as the short bar, the gear is installed on the rotating shaft, and the gear and the short rack can mesh and cooperate.

According to the aforementioned rhythmic gymnastics turnover training auxiliary device, wrist fixing devices are provided on the lower sides of both ends of the grab bar, and the wrist fixing devices and the bottom of the grab bar are fixedly connected by connecting straps.

As described above, a rhythmic gymnastics flip training auxiliary device, the wrist fixing device includes a strap, a hanging ring, a Velcro hook surface, a Velcro cotton surface, the hanging ring is fixedly installed on one end side of the strap, and the Velcro The hook surface is fixedly installed on the side of the other end of the strap, and the Velcro cotton surface is fixedly installed on the side of the strap.

According to the aforesaid rhythmic gymnastics turnover training auxiliary device, the described counterweight is connected to the base through a plug-in connection.

The advantages of the present invention are: the present invention can help the athletes to train the turning action, can help the athlete to perform the practice of simulating the turning action for many times in a short time, can quickly help the athletes to overcome the dizziness when doing the turning action, and improve The athlete's control over the body when flipping in the air can help the athlete consolidate the basic skills of rhythmic gymnastics. A plurality of arc-shaped short racks form an integral arc-shaped rack. When an athlete uses the invention for training, he or she first stands on the upper part of the pedal and binds and fixes the feet through the foot strap, grasps both ends of the grab bar with both hands, and then the first slider rotates around the circular track. Revolution, when the gear contacts and engages with one end of the integral arc-shaped rack, the gear drives the pedal to rotate, and the pedal drives the athlete's body to start self-transmission. When the gear is separated from the other end of the integral arc-shaped rack, the pedal stops rotating, and the athlete's body Thereupon the autobiography is stopped. In the above process, when the feet are facing upwards, the athlete's body begins to autobiography. At this time, the athlete's body revolves around the horizontal axis while the body autobiography simulates the turning action. The present invention can help the athletes when their physical fitness is not enough. The practice of simulating the turning action can effectively help the athletes quickly adapt to the discomfort caused by the turning and overcome it. When the athletes use the present invention to train, they need to mobilize the core muscles of the body to ensure the straight posture of the body. Maintaining is also very helpful for the training of the core strength of the athlete's arms and waist and abdomen. The present invention is also suitable for athletes of different heights. The distance between the pedal and the horizontal axis can be adjusted through the work of the first hydraulic rod. When the distance between the gear and the horizontal axis changes, the radius of the circle where the gear revolves around the horizontal axis changes accordingly. If you want the gear to mesh with the overall arc-shaped rack after the height changes, you need To adjust the overall arc rack, the height of the second slider can be adjusted through the work of the second hydraulic rod, so that the height of the arc rod can be adjusted. For example, when the arc rod moves down, all the third hydraulic rods shrink , the angle between two adjacent arc-shaped short rods changes, and the diameter of the circle where the arc-shaped rods are located is reduced to ensure that the center of the circle where the arc-shaped rods are located coincides with the central axis of the horizontal axis. Through the above adjustments, multiple The radius of the circle where the overall arc-shaped rack composed of arc-shaped short racks is equal to the radius of the circle where the gear revolves around the horizontal axis. At this time, the gear can mesh with the overall arc-shaped rack to ensure athletes of different heights When in use, the present invention operates normally. The present invention has simple and ingenious structure, is convenient to use and has multiple functions, is very helpful to athletes' gymnastics training, and is suitable for popularization and use.
