[0028] like Figure 3 As shown, the height adjustment device 2 includes a first fixed plate 21 and a second fixed plate 22. The first fixed plate 21 is fixedly arranged on one side of the upper end of the training device frame 1, and the second fixed plate 22 is fixedly arranged on one side of the training device frame 1. Two limiting slide bars 23 are fixedly arranged between the first fixed plate 21 and the second fixed plate 22. The lower end of the first fixed plate 21 is connected to a threaded rod 24 through a movable connecting seat. The lower end of the threaded rod 24 passes through the inner side of the second fixed plate 22. The upper and lower ends of the second fixed plate 22 are respectively movably provided with limiting blocks 25. The inner side of the limiting block 25 is fixedly connected to the outer surface of the threaded rod 24. The limiting slide bar 23 passes through a moving block 28. One side of the moving block 28 is fixed to one side of the hinge plate 7. The outer surface of the limiting slide bar 23 is movably connected to the through groove of the moving block 28. A threaded sleeve 29 is fixed on the inner side of the moving block 28. The threaded sleeve 29 is threadedly connected to the threaded rod 24. A transmission disk 26 is fixed to the lower end of the threaded rod 24. A track motor 27 is fixed to one side of the trainer frame 1 through a bracket.

The track motor 27 drives the threaded rod 24 to rotate and then cooperates with the sliding limit of the limiting slide bar 23, thereby realizing the up and down movement of the moving block 28. Since the moving block 28 is fixedly connected to the hinge plate 7, the height of the extending wall 8 can be adjusted.
[0029] Furthermore, in order to reduce the space occupied and the cost, a spring booster device 3 capable of increasing the force is provided at one end of the extension wall 8 to increase the training force;
[0030] like Figure 4As shown, the spring booster device 3 includes a first hinge seat 31, the first hinge seat 31 is fixedly arranged on one side of the moving block 28, a T-bar 32 is fixedly provided on the movable end of the first hinge seat 31, one end of the T-bar 32 is fixedly provided with a connecting ring 33 through a connecting block, a sliding cylinder 36 is movably provided on the outer surface of the T-bar 32, and a sliding plate 35 is fixedly provided on one end of the sliding cylinder 36, the T-bar 32 passes through the inner groove of the sliding plate 35 and is inserted into the sliding cylinder 36, a sliding groove 37 is provided on the outer surface of the sliding cylinder 36, the inner connecting block of the connecting ring 33 passes through the inner side of the sliding groove 37, the connecting ring 33 is located on the outer surface of the sliding cylinder 36, a spring 34 is movably provided between the sliding plate 35 and the connecting ring 33, and a limiting plate 38 is fixedly provided on the other end of the sliding cylinder 36. A second hinge seat 39 is movably provided on one side, and one side of the second hinge seat 39 is fixedly connected to one end of the extending wall 8. The second hinge seat 39 is connected through one end of the extending wall 8, and one side of the movable block 28 is connected to the first hinge seat 31. The extension of the extending wall 8 is achieved through the movable cooperation of the two hinge seats. The T-shaped rod 32 is inserted into the inner side of the sliding cylinder 36 and the sliding plate 35, and then a connecting block is passed through the sliding groove 37. Therefore, the connecting ring 33 can slide on the outer surface of the sliding cylinder 36, and the sliding distance is limited by the sliding groove 37. A spring 34 is provided between the connecting ring 33 and the sliding plate 35. When the extending wall 8 is pulled inward, the sliding plate 35 squeezes the spring 34 and drives the sliding cylinder 36 to slide, thereby achieving the pressurization effect of the spring 34.
[0031] The working principle is as follows: when the present invention is in use, the trainee sits on the adjustable seat 4, first adjusts the height of the adjustable seat 4, and then controls the motor controller 5, and uses the height adjustment device 2 to adjust the height of the extending wall 8. After the adjustment is completed, the trainee holds the handle 9 for training, and uses the spring booster device 3 to increase the force, thereby achieving chest push training.
[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
