Detailed ways

The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

As shown in Figures 1 and 2, a physical training device for mentally handicapped children of the present invention comprises a base 1 on which an elastic pad 2 is laid, and a support column 3 is provided on both sides of the base 1, A beam 4 is arranged between the top ends of the support columns 3, and two vertical guide rods 5 are fixedly arranged at the bottom of the beam 4. The guide rods 5 are hollow rods, and a movable rod is arranged below the guide rods 5. 6. The upper end of the movable rod 6 extends into the guide rod 5 and slides with the guide rod 5, and the upper end of the movable rod 6 is connected with the beam 4 by a spring 7, and the lower end of the movable rod 6 is fixedly provided with a barbell bar 8. The two ends of the barbell bar 8 are provided with counterweights 9; the support column 3 below the barbell bar 8 is provided with an anti-falling hook 10, and the anti-falling hook 10 and the supporting column 3 are enclosed. The depth of the fall prevention section is greater than or equal to 40 cm, and the barbell bar 8 is located in the fall prevention section enclosed by the fall prevention hook 10 and the support column 3 .

The elastic pad 2 is made of conventional elastic materials, such as sponge, cotton cloth, etc. The training personnel can lie on the elastic pad 2 to improve comfort. The supporting column 3 and the beam 4 can be made of high-strength profiles such as rectangular steel, I-beam, and steel pipe. The anti-falling hook 10 plays the role of preventing the barbell bar 8 from falling down to the human body. , the barbell bar 8 is always in the anti-falling interval, preventing the barbell bar 8 from crossing the anti-falling interval and losing the anti-falling function. Use the spring 7 to hold the barbell bar 8, and when the barbell bar 8 is pushed upward, the load changes from light to heavy, which is conducive to the gradual training; The impact force of the barbell bar 8, and at the same time, because the anti-falling hook 10 is provided, the barbell bar 8 falls into the anti-falling hook 10 to prevent it from falling on the human body, which is beneficial to ensure the safety of the training personnel.

The counterweight 9 can be round, preferably, the counterweight 9 is square, and the support column 3 below the counterweight 9 is provided with a horizontal support plate 11, when the barbell 8 falls to the bottom of the anti-fall interval When the counterweight 9 falls on the support plate 11, the support plate 11 plays the role of auxiliary support and anti-fall, and further improves the success rate of anti-fall.
