Description

Lower limb ligament stretching device for physical training

Technical Field

The utility model relates to a sports training auxiliary devices technical field, especially a sports training low limbs ligament stretching device.

Background

As is known, some sports training projects need to stretch the limbs before training to prevent the limbs from being pulled during the training process, leg pressing is one of the basic functions of sports, especially leg training of martial arts and gymnastics and other such sports projects needs to realize the performance of some basic actions by leg pressing, so ligament stretching instruments are used for stretching the limbs before leg pressing or sports in the sports training, however, the existing leg pressing and ligament stretching instruments cannot be correspondingly adjusted according to the leg length of an athlete, and a plurality of instruments need to be prepared for stretching, so that the cost of purchasers is greatly increased, when the existing stretching device stretches the athlete, the athlete can only independently lift the legs, the existing stretching device easily causes unstable standing during the leg stretching process, the athlete is easily injured, and the athlete is easily fatigued after standing for a long time, the stretching time is reduced, and the stretching effect is not ideal.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned condition, in order to compensate prior art not enough, the utility model aims at providing a sports training low limbs ligament stretching device, the effectual current device of having solved stands and stretches the problem that wastes time and energy.

The technical scheme of its solution is, the utility model discloses a bottom plate of left right direction, sliding connection has the seat on the bottom plate, is equipped with the fixed plate that is located the right-hand and fore-and-aft direction of seat on the bottom plate, has seted up fore-and-aft direction and opening on the fixed plate towards the sliding tray on the left side, and sliding connection has two sliding blocks along the fore-and-aft direction distribution in the sliding tray, and the sliding block left end articulates there is the running-board, and both sides are equipped with C shape and opening stabilizer bar down respectively around the bottom plate.

The utility model discloses ingenious, the convenient to use of structure, seat, fixed plate, sliding tray, sliding block, running-board and fixed band that are equipped with for sportsman's pulling stabilizer bar can accomplish the regulation to low limbs ligament tensile strength, has increased the practicality of this device.

Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 4, including the bottom plate 1 of left and right directions, sliding connection has seat 2 on the bottom plate 1, is equipped with the right-hand just fixed plate 3 of fore-and-aft direction that is located seat 2 on the bottom plate 1, sets up fore-and-aft direction and opening towards left sliding tray 4 on the fixed plate 3, sliding connection has two sliding blocks 5 along fore-and-aft direction distribution in sliding

tray

4, and 5 left ends of sliding blocks are articulated to have a running-board 6, and both sides are equipped with C shape and opening stabilizer bar 7 down respectively around the bottom plate 1.

In order to facilitate the sliding of the seat 2, the bottom plate 1 is provided with a left-right direction abdicating groove 8, and the lower end of the seat 2 is inserted into the abdicating groove 8 and can move in the abdicating groove 8.

In order to limit the movement of the seat 2, a plurality of teeth 9 are uniformly distributed at the lower end of the seat 2 along the left-right direction, and a ratchet bar 10 capable of meshing with the teeth 9 is connected on the bottom plate 1 in a sliding manner.

In order to facilitate the release of the limit of the seat 2, a plurality of springs are arranged between the seat 2 and the lower end surface of the ratchet bar 10, and a pressing rod 11 is arranged at the right end of the ratchet bar 10.

In order to fix the feet of the athlete, a C-shaped fixing strap 12 is arranged on the pedal 6.

In order to increase the comfort of the sportsman, the seat 2 is provided with a cushion 13.

When the utility model is used and the lower limb ligament of the athlete needs to be stretched, the athlete sits on the seat 2 and places the feet of the athlete on the pedal plate 6, so that the feet of the patient are inserted into the fixing belts 12 on the corresponding sides to fix the feet of the athlete, thereby preventing accidents in the process of stretching the lower limbs of the athlete;

at the moment, the athlete can stretch the ligament of the lower limb according to the body condition of the athlete, when the tensile strength of the athlete is required to be enhanced, the two hands of the athlete respectively hold the stabilizing bars 7 on the corresponding sides of the athlete and pull the body of the athlete forwards, at the moment, the feet of the athlete respectively drive the pedals 6 on the corresponding sides of the athlete to move outwards under the action of the legs of the athlete, the two pedals 6 respectively move outwards along the sliding grooves 4 through the sliding blocks 5 on the corresponding sides of the pedals, the legs of the athlete start to extend, the angle between the legs is increased, the teeth 9 are continuously meshed with and separated from the ratchet bars 10, the springs are continuously compressed and extended, and if the tensile strength of the ligament of the athlete is continuously increased, the seat 2 is continuously pulled forwards;

after the angle between the two legs is adjusted, the two hands of the athlete can respectively hold the stabilizer bars 7 on the corresponding sides, the upper body of the athlete is pressed downwards, the waist of the athlete can be trained simultaneously, the angle between the two legs is further increased and decreased on the original basis, the flexibility of the athlete for stretching the ligament of the lower limb is facilitated, the stretching strength of the ligament of the lower limb of the athlete is increased by adjusting the angle between the two legs in a small amplitude and in a discontinuous way, and the athlete can adapt to the current stretching strength as soon as possible;

when the lower limbs of the athlete do not need to be stretched, the pressing rod 11 is pushed downwards, the pressing rod 11 drives the ratchet rack 10 to move downwards, the limit on the seat 2 is released, the angle between the two legs is contracted at the moment, the feet of the athlete are pulled out from the fixing belts 12 on the corresponding sides, and the athlete can leave the seat 2.

The utility model has simple structure, convenient operation, novel conception and strong practicability, and the chair, the pedal plate, the sliding block, the stabilizer bar, the sliding groove and the fixed plate can arbitrarily adjust the angle between the two legs of the athlete, thereby adjusting the tensile strength of the ligament of the lower limbs of the sportsman, increasing the practicability of the device, reducing the labor intensity of the sportsman for stretching the ligament when the sportsman stands, effectively increasing the exercise enthusiasm of the sportsman, being provided with the fixing belt which can fix the feet of the sportsman and prevent the feet of the sportsman from falling off in the exercise process of the sportsman, the ratchet bar, the teeth, the spring and the pressing rod are arranged to limit the leftward movement of the seat to prevent the seat from being stretched, the seat moves backwards, which causes failure of stretching and increases the practicability and stability of the device.
