Currently, be expert at industry extensive application is twin-tub foot pump, the exhaust mode of 2 exhaust casings in twin-tub foot pump is
The shortcomings that parallel-connection structure design, parallel-connection structure designs is to require effective capacity of 2 exhaust casings consistent, if 2 exhaust casings
It is vented and unbalanced causes cylinder piston end force inconsistent to causing the unstable working condition of foot pump and by being biased to
Caused by unit piston ring concentrated wear increase so that and reduce effective capacity.And twin-tub foot pump is trampled time
Number only has the 83% of single cylinder foot pump but pedal force is the 150% of single cylinder foot pump.General weight exists in actual operation
75kg, height 175cm adult man be difficult 4bar or more that twin-tub foot pump is stepped on.In addition, being examined from foot pump maintenance angle
Consider, twin-tub foot pump will consider dynamically balanced problem, also carry out the effective capacity balance matching of 2 cylinders after having replaced accessory
Test, so generally only returning factory's maintenance.
It is therefore desirable to a kind of new foot-operated rising bow pump be designed, to realize better using effect and more preferably practicability.
Summary of the invention

Arm, mounting plate, T shape handle, quick connector and PU tracheae composition；The cylinder main body is cylindric hollow pipe, and there is work in inside
Plug, one end are equipped with intake valve, exhaust valve and pressure release pilot hole；The mounting plate is the rising bow pump mount base, is used to support rising bow
Pump；One end of the piston of the cylinder is fixedly connected with lower torque arm, and the one end of cylinder far from piston is fixedly connected with upper torque arm；Institute
The end that pedal is mounted on torque arm is stated, to obtain maximum torque arm length；There is torsional spring between the lower torque arm and upper torque arm；Make
Used time realizes rising bow pump work by foot pedals.
Preferably, the end of above-mentioned mounting plate is equipped with T shape handle, the hanging and fixation for rising bow pump.
Preferably, the exhaust valve of above-mentioned cylinder is connected with PU tracheae.
Preferably, the end of above-mentioned PU tracheae is connected with quick connector.
Preferably, the pressure threshold of the pressure release pilot hole on above-mentioned cylinder is lower than the pressure security value of cylinder, for protecting
Cylinder.
The present invention has the advantage that
After design of the invention, solves the foot-operated rising bow pump of existing twin-tub to user's physical fitness requirement height, energy
The low problem of utilization rate is measured, design of the invention has more excellent capacity usage ratio and lower maintenance cost, more in fact
With property and economy.
