On.
In the present embodiment, more stable in order to make seat 10 slide, the guide rail 200 be square tube, increase guide rail 200 with
The contact area of mute wheel 130.
The working method of the automatically controlled rowing machine is as follows：It when exercise, is powered to electromagnet 43, electromagnet 43 produces flywheel 42
Magnetisation resistance adjusts size of current according to exercise intensity, and electric current is bigger, and reluctance force is bigger, and ribbon 320 is pulled required power
It is bigger；User is sitting on seat 10, and both feet resist rack 1 or step down in foot pedal additionally mounted in rack 1 (Tu Zhong provinces
Slightly, Fig. 1 only draws two installing pipes with threaded hole), both hands hold the handle 6 of ribbon 320 or handle 6 are fixed on seat
On chair 10 (hook for catching on handle 6 can be set) on seat 10, seat is pushed by the strength of lower limb and waist and belly
10 slide back and forth along guide rail 200, pull ribbon 320 by upper limb/lower limb, waist and belly and the strength at back, reach a whole body
The train on of muscle has significant body shaping effect.
When user pulls the handle 6 of ribbon 320, ribbon 320 drives ribbon disk 310 to rotate, and ribbon disk 310 is by unidirectional
Bearing 375 (particular by first bearing seat 361, unilateral bearing 375, sleeve 380 and second bearing seat 362) band movable strap disc
390 rotations, belt pulley 390 drive belt shaft 41 to rotate by belt 50, and belt shaft 41 drives flywheel 42 to rotate, and electromagnet 43 is logical
Flywheel 42 is reduced speed by reluctance force when electric, and Return spring 350 bends flexible deformation at this time；After user unloads power, return
It draws the deformation recovery power of spring 350 that ribbon disk 310 is made to reversely rotate, and then ribbon 320 is made to wind in winding slot 311, and it is unidirectional
Bearing 375 makes belt pulley 390 not reversely rotate, and remains stationary as.
The above, only presently preferred embodiments of the present invention not do limitation in any form to the present invention, any ripe
Those skilled in the art is known in every case without departing from the content of technical solution of the present invention, according to the technical essence of the invention to above real
It applies example and makes any simple modification, equivalent changes and modifications, should all belong to the covering scope of the present invention.
