Described adjustable plate is fan-shaped.When meeting adjustable range, materials are few, reduce costs.
Described base front end both sides are fixed with vertical column, and column upper end is fixed with handrail.
Described column upper end is fixedly connected with by a horizontal connecting rod.Connecting rod can increase the intensity of column, makes handrail solid and reliable.
Compared with prior art, the beneficial effect that the utility model has is:
1, easy to adjust, use safety, back-moving spring makes spacer pin automatic clamping in regulating tank, and ensures that in use spacer pin can not deviate from regulating tank, and working stability uses safety.
2, simple in structure, cost is low, by manually pulling portable plate then to swing, spacer pin is coordinated from different regulating tank, thereby regulates the gradient of treadmill, structure is very simple, manual operation does not need motor to drive, failure rate is low, cost is low.
3, long service life, folding convenient, elastic wheel improves the elasticity of treadmill, improves treadmill service life, improves the support strength of elastic wheel by pull bar, and in the service life of improving elastic wheel, the while is convenient to upwards fold treadmill by pull bar in the time of foldable treadmill.
