In addition, the upper surface of carousel 13 has laid the slipmat, and sealed the pad is fixed on carousel 13 through glue. The user is easily fatigued and has a low ability to balance after exercising, and by laying the anti-slip pad on the turntable 13, the user can stand firmly on the turntable 13 when the user leaves the seat 6, and the user is prevented from losing balance and slipping down.

The working principle is as follows: the invention can simulate rowing to exercise, namely a user sits on a seat 6, two feet are arranged on a pedal 5, two hands hold a push rod 2, the push rod 2 applies force to a piston push rod assembly 3 when pushing the push rod 2, a slide rod 8 of the piston push rod assembly 3 slides along the axial direction of a fixed sleeve 7, because the inner end of the slide rod 8 is provided with a piston 11 which is in sealing fit with the inner wall of the fixed sleeve 7, when the slide rod 8 slides towards the inside of the fixed sleeve 7, gas in the fixed sleeve 7 is pushed into an air cavity 45 of a follow-up mechanism 49 through an air pipe 9, when the user pushes the push rod 2 on one side, because the air pressure of one air cavity 45 is increased, a pneumatic clapboard 44 on a rotary disc 13 moves under the pushing of the air pressure, so that the rotary disc 13 rotates, meanwhile, a displacement sensor 55 on the slide rod 8 detects the change of the displacement of the, the controller 54 processes the electric signal and sends a corresponding instruction to the display screen 53, the display screen 53 plays a steering image according to the received instruction so as to simulate the scene of the gravity center offset effect and the visual change effect when the ship steers, the fixed partition plate 43 is pulled back to the original position by the return spring 46 after the push rod 2 is pulled back, and the turntable 13 is also pulled back to the original position; when the device is used for simultaneously pushing the push rods 2 at the two sides, if the push rods 2 at the two sides are uniformly stressed at each moment of pushing, the rotating disc 13 does not rotate, and a user overcomes the air resistance of the piston push rod assembly 3 to do work to realize the exercise effect; if the two push rods 2 are forced differently at a certain moment in the pushing process, the rotary plate 13 will rotate slightly, the rotation direction will change according to the force on the two sides, and the orientation of the image on the display 53 will change accordingly according to the displacement difference detected by the two displacement sensors 55. Therefore, the design can simulate the change of the position of the hull and play water surface images when the rowing machine is used for body building, not only can a good body building effect be achieved, but also the balance capability of a human body can be trained, and the interestingness of body building is greatly improved.
