detailed description

As shown in FIGS. 1-3 , the utility model includes a base 1 and a column plate 2 fixed on the base 1 .

Said base 1 is symmetrically provided with a left chute 5 and a right chute 4; said left chute 5 is provided with a left slide block 7; said right chute 4 is provided with a right slide block 6; said left slide The inboard one end of groove 5 and right chute 4 is respectively provided with vertical left pulley 9 and vertical right pulley 8; Base 1 is also provided with horizontal left pulley 13 and horizontal right pulley 12. The user stands on the right sliding block 6 and the left sliding block 7 with both feet, and the legs are driven to perform stretching exercise through the sliding of the right sliding block 6 and the left sliding block 7 .

The cross-section of the column plate 2 is n-shaped, and both sides of the column plate 2 are symmetrically provided with slide rails 3; the column plate 2 is also provided with a sliding handle 14, and the two ends of the sliding handle 14 are respectively slidably connected to the two sides. In the slide rail 3; the sliding handle 14 is also provided with a left connecting chain 11 and a right connecting chain 10; one end of the left connecting chain 11 is fixedly connected with the left side of the sliding handle 14, and the other end is bypassed by a horizontal left pulley 13 and the vertical left pulley 9 are fixedly connected with the left sliding block 7; one end of the right connecting chain 10 is fixedly connected with the right side of the sliding handle 14, and the other end walks around the horizontal right pulley 12 and the vertical right pulley 8 and The right sliding block 6 is fixedly connected.

The sliding handle 14 is a cylinder, which includes a sliding handle body 14-1 and a limiting body 14-2 connected to the sliding handle body 14-1 through a spring 14-3. Hold the sliding handle firmly, and the distance between the sliding handle body 14-1 and the limiting body 14-2 becomes smaller, so that the sliding handle 14 can slide smoothly in the slide rail. When the hand strength is relaxed, the limiting body 14-2 bounces. Open, the diameter of the sliding handle 14 becomes larger, thereby being stuck in the slide rail 3, and realizing the limit function.

The outer surfaces of the sliding handle body 14-1 and the limiting body 14-2 are covered with an elastic material layer to increase the frictional force and further improve the limiting effect.

The edge of the slide rail 3 is provided with a scale, and the training effect can be quantified by observing the scale.

The cross-section of the right sliding block 6 and the left sliding block 7 is L-shaped, which conforms to ergonomics and is conducive to exerting force on both feet.

The use process of the utility model:

First adjust the sliding handle 14 to a suitable height according to the height of the user, then step on the left sliding block 7 and the right sliding block 6 with both feet, hold the sliding handle 14 with both hands, keep the body straight, and slowly hold and slide with both hands The handle 14 makes the spring 14-3 compressed, and the distance between the sliding handle body 14-1 and the limiter 14-2 is reduced. Under the action of gravity, the sliding handle 14 slowly slides down, driving the left sliding block 7 and the right sliding block 6 to Sliding on both sides, the distance between the legs gradually increases. When the body reaches the limit, release the hands, the limit body 14-2 springs off, and the diameter of the sliding handle 14 becomes larger, so that it is stuck in the slide rail 3 to realize the limit Features.
