Specific embodiment

To further illustrate each embodiment, the utility model is provided with attached drawing.These attached drawings are in the utility model discloses A part of appearance mainly to illustrate embodiment, and can cooperate the associated description of specification former come the running for explaining embodiment Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and sheet are practical new The advantages of type.Component in figure is not necessarily to scale, and similar component symbol is conventionally used to indicate similar component.

Now in conjunction with the drawings and specific embodiments, the present invention will be further described.

Shown in referring to Figure 1 to Figure 7, a kind of treadmills provided by the utility model, comprising: one transmission mechanism 10, two Crank (not shown) and two pedal gears, two pedal gears pass through two that two cranks connect the transmission mechanism 10 respectively The structure of side, the transmission mechanism 10 and crank is conventional structure, please refers to documents or routine in background technique Elliptical stepper, this will not be detailed here.

The pedal gear includes: that pedal 21, running-board bracket 22, adjusting swing rod 31 and fixing piece, the pedal 21 are fixed on On running-board bracket 22, one end of the running-board bracket 22 connects the crank, and the other end is connected with the first idler wheel 23；Specifically, institute It states running-board bracket 22 and is equipped with the first connecting hole 222, and is corresponding with the centre bore of the first idler wheel 23, and realized by drive-connecting shaft 24 Pivot joint.

Described one end (i.e. upper end in Fig. 1) for adjusting swing rod 31 is articulated on running-board bracket 22, and the other end is (i.e. in Fig. 1 Lower end) be connected with the second idler wheel 32；Specifically, the first pivoted hole 221 is offered on the running-board bracket 22, the adjusting swing rod 31 one end offers the second pivoted hole 311, and first pivoted hole 221 is corresponding with the second pivoted hole 311 and passes through a pivot Spindle 25 wears connection, to realize the two pivot joint.Likewise, the lower end for adjusting swing rod 31 is equipped with the second connecting hole 312, and It is corresponding with the centre bore of the second idler wheel 32, and pivot joint is realized by drive-connecting shaft 33.

The adjusting swing rod 31 can make in the first position (referring to shown in Fig. 2, Fig. 3) being folded on running-board bracket 22 with expansion Second idler wheel 32 is supported between the second position (referring to shown in Fig. 4, Fig. 5) of base of running exerciser 11 and swings；The fixing piece is solid It is scheduled on running-board bracket 22, the fixing piece for fixing the adjusting swing rod 31 when being located at first position and the second position respectively.

Specifically, the fixing piece is a spring leaf 40, the spring leaf 40 is fixed on running-board bracket 22, the spring 40 On piece has a clamping portion 41, and the adjusting swing rod 31 offers the first bayonet 313 and the second bayonet 314, the adjusting swing rod 31 when being respectively at first position and the second position, and first bayonet 313 and the second bayonet 314 respectively correspond spring leaf 40 Clamping portion 41, the clamping portion 41 of the spring leaf 40 are connected on the first bayonet 313 or the second bayonet 314 with the fixation adjusting Swing rod 31.As shown in figure 3, the clamping portion 41 of spring leaf 40 is connected on the first bayonet 313, swing rod 31 will be adjusted and be fixed on One position.As shown in figure 5, the clamping portion 41 of spring leaf 40 is connected on the second bayonet 314, swing rod 31 will be adjusted and be fixed on Two positions.The present embodiment fixing piece uses spring leaf 40, and spring leaf 40 has certain elastic force, in this way, swing rod can will be adjusted 31 directly switch between the first location and the second location, such as when adjusting swing rod 31 is in first position, to second position side Swing rod 31 is adjusted to moving, because of the positional shift of the first bayonet 313,41 elasticity of clamping portion of spring leaf 40 is detached from first card Mouth 313 continues to be rocked to the second position so that adjusting swing rod 31, at this time the clamping portion 41 of the corresponding spring leaf 40 of the second bayonet 314, Clamping portion 41 is connected in the second bayonet 314 under the action of the elastic restoring force of spring leaf 40, and then realizes switching, operation letter Just.Of course, in other embodiments, fixing piece can also plug fixed mode with such as bolt etc. and be replaced, only exist It when each switching position, is intended to first extract the devices such as bolt, then the fixed movement plugged, operate relatively complicated.

Further, in the present embodiment, blocking part 223 is additionally provided on the running-board bracket 22, the blocking part 223 is to be sticked Face is kept out in adjusting 31 surface of swing rod.When the adjusting swing rod 31 is rocked to the second position by first position, kept out by described Portion 223 contradicts, and adjusts swing rod with limitation and continues to swing, the stability of reinforcement structure.Further, the blocking part 223 is gone back It is extended with a plug 224 to 31 direction of swing rod is adjusted, it is described to adjust the socket 315 that corresponding plug 224 is also provided on swing rod 31, When the adjusting swing rod 31 is contacted on blocking part 223, the plug 224 is inserted in socket 315, further reinforcement structure Stability, prevent from deviating.

When sitting is taken exercise, swing rod 31 will be adjusted and be folded on the first position on running-board bracket 22, at this time on running-board bracket 22 First idler wheel 23 is supported in base of running exerciser 11, and foot is placed on pedal 21 and is performed physical exercise；When standing is taken exercise, swing rod will be adjusted 31 are expanded to the second position for making the second idler wheel 32 be supported in base of running exerciser 11, and the first idler wheel 23 of running-board bracket 22 is outstanding at this time Sky, person taking exercise's tiptoe stand directly on pedal 21 against crank position and perform physical exercise, and can be good at the angle that simulation is normally walked Degree；Two kinds of physical training styles for making treadmills can be realized sitting and stand, and be tiptoe against crank position, to person taking exercise with Normal exercising way of marking time, has structure simple, the good feature of comfort；It is simple and compact for structure, it is multiple functional, relatively Stretching, extension heel string under-chassis bottom kneading massage effect is realized under low cost.

Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art is answered This is understood, in the spirit and scope for not departing from the utility model defined by the appended claims, in form and details On the utility model can be made a variety of changes, be the protection scope of the utility model.
