Description

An auxiliary training device for preventing ligament strain

technical field

The invention relates to the field of physical training auxiliary equipment, in particular to an auxiliary training device for preventing ligament strain.

Background technique

Muscles, ligaments, fascia, synovium, etc. are involved during weight-bearing activities or body position changes. When joints are twisted or muscles contract suddenly, a few fibers may be broken, and small joints may move slightly, causing strain. Ligament strain is generally due to external force during labor or exercise that makes the joint movement exceed the normal physiological range, causing the ligament around the joint to be strained, partially broken or completely broken, which is called joint ligament sprain. The most prone to joint and ligament sprains are the knee joints, finger joints and ankle joints.

After competitive sports training or long-distance running, mountain climbing or cycling, the muscles of the legs and waist will be sore, and the flexibility of the legs can be stretched to relieve muscle soreness. Regular stretching can bring many benefits: Relief Tighten the leg muscles to make the body more relaxed; improve the flexibility of the leg muscles and expand the range of motion of the body. Now there are generally two ways to stretch the ligaments. One is two people sitting facing each other, with their legs straight, their feet touching each other, holding each other's hands or wrists tightly, their backs straight, and their necks and spines kept on the same level as possible. First, use the buttocks as the axis to pull the opponent's arm; the second is to use other people's assistance to press to complete the split leg. Because the strength of others is unpredictable and you can't control it, it will cause leg muscles and ligaments to be strained, causing serious damage to the practitioner. Injury and pain, and when training alone, the training is mainly carried out by the trainer's own strength, and the training effect is relatively poor.

Then, the output shaft of the motor 16 is connected with the reel 19 through the bevel gear set 18, the outer surface of the reel 19 is wound with a sling 20, and the top of the drive box 15 has a through hole for the sling to pass through, and the support frame 2 is equipped with a first winding post 21 at the center of the bottom of the top crossbeam. The side of the top crossbeam of the support frame 2 near the bottom plate 1 is connected with a triangular bracket 22. The top and bottom of the triangular bracket 22 is equipped with a second winding post 23. One end of 20 bypasses the first winding post 21 and the second winding post 23 and is connected with a restraint waistcoat 24, and both sides of the side surface of the support frame 2 near the bottom plate 1 are equipped with a support bar 25, and the top of the support bar 25 Control buttons 26 are all installed.

Further, the limiting baffle 27 includes an upper baffle 28 and a lower baffle 29, and the surfaces on the opposite sides of the upper baffle 28 and the lower baffle 29 are all provided with arc-shaped grooves 30, and the upper baffle 28 and the lower baffle are 29 are connected by bolts 31, and the top of the bolts 31 is provided with a turning handle, and the bolts 31 control the locking of the upper baffle 28 and the lower baffle 29, so that the position of the limit baffle 27 can be adjusted, thereby limiting the sliding The maximum sliding distance of the sleeve rod 8 prevents the ligament from being too large at an instantaneous sliding angle.

The area of the through hole formed after the arc groove 30 is closed is slightly smaller than the cross-sectional area of the guide rod 7, and the surface of the arc groove 30 is provided with a rubber layer, and the upper baffle plate 28 and the lower baffle plate 29 are close to each other so that the arc groove 30 Then put together, and then bind the outer peripheral surface of the guide rod 7, and realize that the rubber layer can increase the friction force and protect the guide rod 7 at the same time.

Reinforcing ribs are connected between the bottom ends of both sides of the backing board 5 and the surface of the fixing board 3 , and form a triangular structure to strengthen the resistance that the backing board 5 can withstand.

The bondage vest 24 has a short half-length structure, and the parts on both sides of the front chest are bonded by Velcro. It can be worn by people of different sizes, and the Velcro is more close-fitting.

The two control buttons 26 on the top of the handle bar 25 are respectively an up key and a down key, and the control buttons 26 are electrically connected with the motor 16, and the motor 16 is controlled forward and reverse through the control buttons 26.

The suspension rope 20 is a wide and flat wire rod, which prevents the suspension rope 20 from slipping during stretching and turning.
