Description

Technical Field

[0001] This invention relates to the field of sports training auxiliary equipment technology, and more specifically to an auxiliary device for practicing curves on ice. Background Technology

[0002] The main technical movements in figure skating include skating, jumps, spins, and footwork. Skating is the foundation of figure skating; good skating technique allows athletes to achieve good horizontal speed and stability, and provides a guarantee for completing high-difficulty jumps. To promote the long-term development of figure skating, the Chinese Figure Skating Association has introduced a figure skating level test, which consists of two parts: skating footwork and free skating. The skating footwork assessment is designed to encourage athletes to focus on training their skating abilities. In the basic and level one footwork assessments, the crossover step is particularly emphasized. This movement is crucial for gaining speed on curves, but beginners often hesitate to shift their weight to the outside due to fear, leading to incorrect edge usage and incorrect weight distribution during the crossover step, thus affecting their overall basic skating technique. Meanwhile, in speed skating and short track speed skating, curve technique is key to victory. The angle of inclination on curves is greater than in figure skating, requiring more practice time on curves. The angle of inclination on curves at high speeds is also a source of fear for beginners. Furthermore, existing professional speed skating cornering techniques training devices are not suitable for beginners, resulting in poor training effectiveness.

[0003] Therefore, how to provide an ice cornering practice aid device that is simple in structure, easy to operate, can eliminate beginners' fear, and help them quickly master cornering skills is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the present invention provides an ice track cornering practice aid device that is simple in structure, easy to operate, can eliminate the fear of beginners, and help beginners quickly master cornering skills.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An assistive device for practicing curves on ice includes:

[0007] A triangular support, the bottom of which is provided with a spike for inserting into the ice surface, and the top of which is fixed with a support base;

[0008] A central vertical shaft, one end of which is fixedly connected to the top of the support base, and the other end is fitted with a fixed bearing;

[0009] A rotating sleeve, which is fitted onto the outer ring of the bearing;

[0010] An auxiliary pull rod is provided, one end of which is hinged to the outer wall of the rotating sleeve, and a gripper is hinged to the rod wall near the other end of the auxiliary pull rod.

[0011] As can be seen from the above technical solution, compared with the prior art, the present invention discloses an auxiliary device for practicing ice curves. In use, the device is first placed in a suitable position on the ice rink, the triangular support is opened, and the spikes are inserted into the ice surface for stability. Then, the athlete accelerates towards the device, gently grasps the handrail with one hand, tilts their body, and lightly pulls the auxiliary lever to generate a small centripetal force, assisting in the gliding process. Therefore, this auxiliary device can help athletes quickly overcome psychological fear, find their gliding center of gravity, and form muscle memory with correct edge control and center of gravity position. This helps athletes quickly master the key points of the movement, build a solid foundation for gliding, and improve gliding speed. Furthermore, the device has a simple structure and is easy to operate.

[0012] Furthermore, the rotating sleeve has a pin through-hole penetrating its upper and lower end faces, and also includes:

[0013] A limiting sleeve is fitted onto the central vertical shaft and located below the rotating sleeve. A semi-circular sliding groove is provided on the top surface of the limiting sleeve, and a sliding connecting cylinder is placed in the semi-circular sliding groove. The limiting sleeve has a semi-circular receiving cavity arranged opposite to the semi-circular sliding groove inside.

[0014] A reset spring is provided inside the semi-circular receiving cavity. One end of the reset spring is fixedly connected to one side wall of the semi-circular receiving cavity, and the other end extends out of the other side wall of the semi-circular receiving cavity and is fixedly connected to the outer wall of the sliding connecting cylinder.

[0015] A limiting pin passes through a pin through hole and is inserted into the sliding connecting cylinder.

[0016] The beneficial effects of adopting the above technical solution are as follows: For multiple people practicing cornering techniques, first, the limiting pin is passed through the pin insertion hole and inserted into the sliding connecting cylinder, so that the rotating sleeve can only rotate half a turn and automatically returns to its original position after rotation. Multiple athletes form a queue and accelerate to the device in turn. The first athlete grips the handle with one hand to complete the cornering action. At this time, the return spring is stretched. After the action is completed, the grip is released, and the auxiliary lever automatically returns to its original position under the elastic force of the return spring. The second athlete accelerates and grips the telescopic bar with one hand to complete the cornering action, and so on. For single-person skating, the limiting pin needs to be removed, allowing the rotating sleeve to rotate freely without restriction. This enables single-person "cross-step" assisted skating practice, where one person grips the auxiliary lever and performs continuous circular skating movements around the cornering practice auxiliary device as the center. This is very helpful for beginners practicing "cross-step". Therefore, this auxiliary device not only enables single-person ice skating circle training but also allows multiple people to practice cornering actions simultaneously, greatly improving the applicability of the device.

[0017] Furthermore, the auxiliary tie rod is a telescopic rod.

[0018] The beneficial effects of adopting the above technical solution are that the length can be adjusted, making it easy to control the radius of the curve during training. That is, when extended, it is suitable for large curves and large circles, and when contracted, it can be used to practice small curves and small circles.

[0019] Furthermore, multiple counterweight rods are evenly hinged to the outer wall of the rotating sleeve.

[0020] The beneficial effect of adopting the above technical solution is that it provides a certain balance and stability to the center of gravity when the trainee holds the auxiliary lever. Attached Figure Description
