Description

Technical Field

[0001] The invention relates to the technical field of ligament stretching training, in particular to a ligament stretching training device for rhythmic gymnastics and a use method thereof. Background Art

[0002] Ligament stretching is often required during rhythmic gymnastics training, especially for students who are just starting to learn dance. Ligament stretching is particularly important. In the prior art, artificial ligament stretching is generally used, that is, it is necessary to ask others to help the trainee to open their legs to a certain angle, so as to complete the ligament stretching. This takes up other people's time and affects their training. In addition, more physical strength is required when assisting in stretching, which affects the other person's own training. Therefore, a single-person stretching device has appeared on the market, which can open the trainee's legs to a certain angle. However, the device has the following defects during use: its opening and closing both need to be operated by turning a hand wheel. If the trainee suddenly has cramps during use, his legs cannot be relieved quickly, which may cause damage to his legs. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a ligament stretching training device for rhythmic gymnastics and a method of use, which solves the above-mentioned problems.

[0005] As a further solution of the present invention: both sides of the top of the movable seat are fixedly connected with side limiting plates, and the side limiting plates are used to limit the two sides of the legs to prevent them from falling off.

[0006] As a further solution of the present invention: the limit mechanism includes a limit block arranged above the guide rail, the bottom of the limit block is provided with a step groove adapted to the walking groove, the inner cavity of the limit block is provided with a through groove, the inner cavity of the through groove is threadedly connected with a threaded rod through the threaded groove, and the inner cavity of the limit block is slidably connected with a push rod through the sliding groove, one end of the two push rods penetrates into the inner cavity of the threaded groove, and the opposite ends of the two push rods are fixedly connected to the top block. The bottom of the threaded rod is provided with a frustum section that is larger at the top and smaller at the bottom. When in use, the position of the limit block is adjusted according to the use requirements to limit the position of the walking wheel to prevent it from being over-stretched. After the limit block is moved to the position, the threaded rod is rotated, and the threaded rod moves downward in the through groove along the threaded groove, and the top block on the side of the push rod is squeezed by the frustum section, and the push rod slides outward along the sliding groove and abuts against the side wall of the walking groove for fixing, which can play the role of an effective limiter to prevent electronic components from being over-stretched due to errors.

[0007] As a further solution of the present invention: the lateral swing arm is driven by a swing motor, and the transmission wheel is driven by a transmission motor.

[0008] As a further solution of the present invention: the guide track is composed of a transversely arranged steel bar and two arc-shaped steel bars, and the two arc-shaped steel bars are centered at the connection between the transverse swing rod and the motor. Through the setting of the guide track, the movement of the moving seat is more stable, and it will not easily produce excessive shaking and displacement, thereby reducing the possible damage caused by stretching and achieving better use effect.

[0009] As a further solution of the present invention: the end of the support frame extends to just above the connection between the movable seat and the pull rope, and the movable seat is lifted by pulling the pull rope, and can be stretched up and down when horizontally stretched, and the stretching can be selected to be larger.

[0010] As a further solution of the present invention: it also includes an operating handle connected to the side of the base through a wire, and the operating handle is electrically connected to the swing motor and the transmission motor respectively, which can conveniently control the movable seat to open left and right or swing up and down to stretch at different angles.

[0011] A method for using a ligament stretching training device for rhythmic gymnastics comprises the following steps: Step 1: When using, the trainer sits on the base and places his legs between the side limit plates on the two moving seats.

After moving the limit block to the position, rotate the threaded rod, and the threaded rod moves downward along the threaded groove in the through groove. The top block on the side of the top rod is squeezed through the truncated cone section. The top rod slides outward along the sliding groove and abuts against the side wall of the walking groove for fixation. It can play an effective limiter role to prevent electronic components from being over-stretched due to errors. For leg stretching, the learning process is judged according to the change from ligament stretching length to stability. At the same time, the potential for performing difficult movements can also be judged according to the maximum stretching of the ligament. Step three, perform lateral stretching. Control the swing motor through the operating handle to drive the lateral swing rod to rotate, and drive the moving seat to move. At this time, the walking wheel moves in the walking groove on the guide track to stretch the ligaments in the style of opening the legs. Drive the transmission wheel to rotate through the transmission motor to drive the pull rope to retract and release, and lift the moving seat. The moving seat drives the connecting part to move up and down at the end of the lateral swing rod to perform leg lifting stretching training.
