Description

Technical Field

[0001] This utility model relates to the field of training equipment technology, and in particular to a ligament stretching device for sports. Background Technology

[0002] Stretching is actually a form of warm-up. Before strenuous activity, you should stretch your muscles to prevent sudden acceleration from overwhelming the ligaments, which could lead to injury, tearing, or strain. Stretching improves the body's ability to withstand bending and the flexibility of various limbs.

[0003] In the process of stretching leg ligaments, ligament stretching equipment is needed for auxiliary training. In the existing technology, patent CN206295549U discloses a ligament stretcher, which includes a ligament stretcher body. The ligament stretcher body includes a connecting screw, and two telescopic tubes are hinged to the rod of the connecting screw. A lifting eye nut is screwed onto the connecting screw; a tightening strap passes through the lifting eye nut. The telescopic tubes consist of an outer tube, an inner tube, and a V-shaped spring clip; several adjustment clips are provided on the side of the outer tube. The inner tube has a through hole on its side, and a V-shaped spring clip is installed inside the inner tube. The protrusion on the side of the V-shaped spring clip passes through the through hole of the inner tube to the outside. The inner tube is installed inside the outer tube and is fixed by the protrusion on its V-shaped spring clip being engaged with the adjustment clip hole of the outer tube. A connecting nut A is welded to the end of the telescopic tube, and a union screw is screwed onto the connecting nut A. A buckle is connected to the union screw, and a foot cover is connected to the buckle. It helps to improve the flexibility and suppleness of the legs and has the advantages of good effect, convenient storage, and low cost.

[0004] The aforementioned patented technology involves pulling the tightening band during actual splits ligament stretching training. This causes the foot sleeves to pull the leg backward, thus stretching the leg ligaments. However, especially for beginners with tight ligaments, achieving the splits can be very painful. Therefore, beginners often loosen the tightening band, causing the two telescopic tubes to loosen and reset, severely impacting the training effect. In view of this, this application proposes a ligament stretching device for sports. Utility Model Content

[0064] Working Principle: In actual use, the stretching machine allows the user to sit on the seat 100 and place both legs within the two L-shaped plates 300. The controller 1000 then activates the stepper motor 404, which in turn rotates the threaded column 405. This rotation moves the slider 402, which in turn moves the two adjusting rods 403, which in turn push the two rotating rods 200, causing them to fan out and thus stretch the user's legs, achieving a splits ligament stretch. The stretching machine unfolds slowly under the action of the stepper motor 404, allowing for gradual increases in training intensity. It also offers good stability during ligament stretching, maintaining a consistent stretching angle, effectively improving training results and enhancing practicality. Furthermore, the user can grip the handles 1103 during the splits stretching exercise, providing effective cushioning for beginners experiencing pain, making it easier for them to use.
