Description

The magnetic damping Foldable running apparatus

The utility model relates to a kind of treadmill, particularly a kind of Foldable running apparatus with magnetic damper control.

Existing treadmill, disclosed as patent 95213084 (Fig. 1, shown in Figure 2) is a kind ofly to be provided with magnetic damper at the frame front end near the resistance wheel place, cover not magnetic conduction copper sheet of one deck on its resistance wheel wheel face, several permanent magnets are housed on the magnetic receiver, magnet frame is adjusted the gap that button comes regulating magnet and flywheel by rollable cable wire and multisection type, obtaining different brake drags, but this treadmill with magnetic damping control has following shortcoming:

(1) magnetic damper in the past is by the gap between cable wire regulating magnet and the flywheel, when installing, cable wire is difficult to adjust minimum clearance, often magnet meeting grazing flywheel is obstructed running, if primary clearance increases, the magnetic damping effect is weakened, so that lose the function of regulation and control velocity, in use the elongation of its steel wire of bowden cable can change, the gap that originally mixed up is increased, the magnetic damping effect is weakened, and the user often is difficult for readjusting.

(2) the not magnetic conduction copper sheet of resistance wheel wheel face covering, the cost height is made difficulty.

(3) existing Foldable running apparatus because the latch gap makes handrail unstable, or adopts screw-clamped, because the handgrip lever is long, can't clip again, causes dangerous easily.

(4) frame of existing treadmill directly contacts with ground, and when riding running board, damping effect is relatively poor.

The purpose of this utility model provides a kind of easy to adjust, and easily folding, good damping effect can better be controlled the magnetic damping Foldable running apparatus that resistance wheel rotates.

The utility model comprises frame, stand, magnetic damper, magnetic damper is equipped with at frame front end flywheel place, magnetic receiver is by regulating gap with flywheel with the affixed adjustment button of cable wire, 1-2 piece high magnetic energy magnet is arranged at the top of magnetic receiver, the aluminium circle relative motion that can cover with the flywheel appearance, regulating on the support junction of cable wire and magnetic receiver, one upper end is arranged is screw thread, and the lower end is the stop screw of polished rod, a spring once on the polished rod.

Have on the frame one revolve the hand screw can fastening frame and stand, make handgrip stable.When folding, revolve the hand screw, and the folding frame that makes progress, the frame location inserted with the dribbling latch.

The yielding rubber filler strip is housed under the running board of frame, and the frame bottom is equipped with the yielding rubber cover respectively with the bottom of stand.

The utility model is owing to adopt said structure, the cylindrical of flywheel studs with a circle aluminium circle, 1-2 piece high magnetic energy permanent magnet is laid on magnetic receiver top, magnetic receiver one end is hinged on the frame, the other end is connected with stepless vernier knob with cable wire, and when the band of running drove the flywheel rotation, flywheel outer ring conductor cutting magnetic line produced vortex flow, the relative magnetic field work done of this vortex flow forms the moment of resistance that stops flywheel to rotate.

A stop screw is equipped with in the junction of cable wire and magnetic receiver on the adjusting support, stop screw top is screw thread, the bottom is a polished rod, screw thread can be finely tuned the minimum clearance of permanent magnet and aluminium circle, purpose makes not grazing of permanent magnet aluminium circle under minimum clearance, thereby guarantee the maximum damping of performance permanent magnet, when the steel wire length elongation of cable wire, because of vernier knob leaves pretension length, avoid the user to be difficult to regulate, can make permanent magnet bring into play maximum damping, when the polished rod part of stop screw bottom can make magnetic receiver move up and down, can deflection, return spring is enclosed within on the polished rod, is convenient to the cable wire end and regulates height up and down with nut, and the aluminium circle that the flywheel wheel face covers conducts electricity, more cheap than copper, its riveted joint process is simple, easy to operate, and 1-2 piece high magnetic energy magnet best results is installed on the magnetic receiver top, easily adjust the gap of flywheel and magnetic receiver, thereby reach the purpose of control treadmill speed.

The hand screw that revolves of frame front makes frame and stand fastening, guarantees the handgrip stability and safety, and the dribbling latch, and frame and stand after folding are fixed, make folding after treadmill only take less space.

One deck rubber blanket is arranged between running board and the frame, and the rubber sleeve of frame, stand bottom can play the effect of damping, and the user is as running on the grass meadow.
