Description

Treadmill that can unidirectional packing belt

Technical field

The utility model relates to a kind of fitness equipment, particularly relate to a kind of produce both feet strengthen the span movement effects can unidirectional packing belt treadmill.

Background technology

Referring to shown in Figure 1, general running fitness equipment 10 consists predominantly of a base 11, one extends upwardly the preceding bar 12 that is located at place, base 11 the place aheads, rocking bar 13 before two movable axis are located on the bar 12, an electro-motor 14 that is fixed in base 11 fronts, a frame 15 that is installed in base 11 back, one group of axle is located at the belt pulley set 16 of frame 15 fronts, one group of crank wheels 17 that are arranged on frame 15 back, one group of press nips 18 that is arranged on place, frame 15 tops, and two drive-connecting shafts are located at the pedal group 19 that places in the middle of crank wheels 17 and the rocking bar 13 can trample for the human foot, belt pulley set 16 has small one and large one belt pulley 161, article 162 and two, belt 163,164, crank wheels 17 have a crankwheel 171 and two axles are located at crankwheel 171 centers and crank 172 terminal and pedal group 19 do pivot joint interlocks, big belt pulley 161 is by belt 163 and electro-motor 14 solderless wrapped connection interlocks, small belt pulley 162 is by belt 164 and crankwheel 171 solderless wrapped connection interlocks, after starting electro-motor 14 runnings, can drive belt pulley set 16 and 17 runnings of crank wheels, thereby can drive pedal group 19 and do front and back displacement swing, the human foot tramples on pedal group 19 just can make road-work.

Above-mentioned press nips 18 has the effect of road-work really, yet still have deficiency to need to improve in the use, action swings before and after the lower end of the front end of pedal group 19 and rocking bar 13 is articulated and can does, the rear end of pedal group 19 then is articulated with crank 172 ends and does the circular turned action, whole pedal group 19 is subjected to the restriction of rocking bar 13 and crank 172 movement locus, the amount of movement of longitudinal separation is also little, when the human foot tramples when carrying out road-work on this pedal group 19, can only make the motor pattern of similar dogtrot, user's step can't strengthen span and move, and therefore the running fitness equipment of this structure kenel can't satisfy the demand of user's large amount of exercise.

The utility model content

The utility model purpose be to provide a kind of user of allowing increase the motion of step span can unidirectional packing belt treadmill.
