Description of drawings

Fig. 1 is the structural representation sketch of treadmill of a kind of adjustable armrest height of the utility model.

Among the figure, 1-motor, 2-small pulley, the big belt wheel of 3-, 4-pinion, 5-gear wheel, 6-cylindrical cam, 7-roller follower, 8-connecting rod, 9-treadmill underframe, 10-treadmill handrail, 11-handrail lifting button, the 12-band of running, the stand of 13-handrail, 14-cross bar.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is carried out detailed narration.Fig. 1 is the structural representation sketch of treadmill of a kind of adjustable armrest height of the utility model.As can be seen from the figure, comprisetreadmill underframe 9,handrail stand 13; Treadmillhandrail 10, running are with 12, wherein, run and are with 12 to be contained on thetreadmill underframe 9;Handrail stand 13 is packed on thetreadmill underframe 9; Treadmillhandrail 10 is installed in thehandrail stand 13; This treadmill also comprises,handrail lifting button 11; Wherein, handrail is housed on the describedtreadmill underframe 9 and regulates transmission device; Thistreadmill handrail 10, liftable inhandrail stand 13; Press and regulatehandrail lifting button 11, can promote or reducetreadmill handrail 10 height.

Described handrail is regulated transmission device, comprisesmotor 1, beltpulley transmission component 2,3, gear-drivenassembly 4,5, cylindrical camroller transmission component 6,7; Wherein, the output of describedmotor 1 is connecting beltpulley transmission component 2,3; Beltpulley transmission component 2,3 outputs are connecting gear-drivenassembly 4,5; Gear-drivenassembly 4,5 outputs are connecting cylindrical camroller transmission component 6,7.

Cam 6 in the described cylindrical camroller transmission component 6,7 rotates, and drivesroller follower 7 and moves up and down; Handrailmobile link 8 withroller follower 7 welds together moves up and down withroller 7 rotations.

Describedhandrail lifting button 11, the start-stop ofcontrol motor 1, thisbutton 11 is contained on thetreadmill handrail 10.

The left andright sides handrail 10 of described treadmill is affixed throughcross bar 14 to be an integral body, moves up and down with handrailcarriage release lever 8 jointly.

The running of the utility model embodiment is: presshandrail lifting button 11, electric motor starting drivessmall pulley 2 and rotates, and small pulley is givenbig belt wheel 3 through driving-belt with transmission of power, accomplishes once to slow down.Big belt wheel 3drives pinion 4 and rotates, and pinion is givengear wheel 5 through engaged transmission with transmission of power, accomplishes for the second time to slow down.Cylindrical cam 6 is coaxial with gear wheel, therefore with the same rotational speed of gear wheel.Cylindrical cam rotates backpromotion roller follower 7 and moves up and down, and roller follower driveningrod 8 moves.The slide bar of treadmill handrail and connectingrod 8 weld together, so the handrail litter follows connecting rod and move up and down together, carry out up and down highly adjusting thereby drive the treadmill handrail.

The characteristics of the utility model are:

Because thehandrail 10 of the utility model has the up-down adjustment function, can be adjusted to suitable height according to sporter's height, let the sporter keeps easily, posture freely in motion process, reach desirable movement effects.

The regulating system of handrail is a power adjustment, and power source is a motor, and the transmission of driven by motor belt wheel is accomplished once and slowed down, and again transmission of power is arrived gear drive, accomplishes secondary speed-reducing.Transmission of power after the deceleration is to the cylindrical cam transmission, and the cam driven roller follower moves up and down.Handrail carriage release lever and roller follower weld together, and move up and down thereupon, accomplish height of armrests and regulate.This regulating system adopts cam mechanism, and the space that occupies is less, and is simple in structure, compact.

The switching of handrail lifting button control motor is arranged on this button on the handrail, and aspect sporter regulates.As long as the sporter presses lifting button,, when being adjusted to correct position, unclamping lifting button and can accomplish adjusting just handrail can up-down adjustment.Adjustment process is convenient, simple.

Two side handrails connect as a whole through cross bar, the up-down regulating system need not dispose at the both sides arm rest simultaneously, as long as be configured in any arm rest, have both guaranteed the uniformity that two side handrails go up and down, and have also reduced the cost of product.

Present embodiment is the example in the utility model design, in this design down, and those skilled in the art; Can embodiment for referencial use, infer a plurality of technical schemes, still; All technical schemes under this design are all within the claim protection domain of the utility model.
