Abstract

DC60 Bicycle Bellows Cylinder included That is adjusted to mount on a bicycle frame with a cylinder hole where the piston slides back and forth in it, the crankshaft supported to rotate on the cylinder. And driven as a match for the piston By means of connecting rods And the drive mechanism for matching the crank axis At the bicycle chain being driven When the pedal is activated To drive the bicycle chain, the bicycle chain drives the crank axis to turn it and thus cause the pistons to move accordingly. In the hole of the cylinder to pump air Through the outlet of the cylinder Bicycle pump Cylinder included That is adjusted to mount on a bicycle frame with a cylinder hole where the piston slides back and forth in it, the crankshaft supported to rotate on the cylinder. And driven as a match for the piston By means of connecting rods And the drive mechanism for matching the crank axis At the bicycle chain being driven When the pedal is activated To drive the bicycle chain, the bicycle chain drives the crank axis to turn it and thus cause the pistons to move accordingly. In the hole of the cylinder to pump air Through the outlet of the cylinder

Claims (8)

1. An air pump structure that has been adjusted to be fixed to the frame of the bicycle. Bike with Bicycle chain connected to the pedal, the air pump consists of The milled cylinder is attached to a bicycle frame with a positive cylinder hole with a piston. Moving in it and the crank axis being supported to rotate on the cylinder And connectable, powered With the piston by connecting rods And a center hole for connecting the crank axis to the bicycle chain being driven where such a center hole is made in the crank axis where the drive shaft is received. Inside to be able to move along the axis The drive rod has an outer end protruding from the center hole of the Crank axis With the chain wheel adjusted to be munched on by the traction chain The drive axis has a channel With axial length And crank axes with holes extending along the radius. One end of the pin is attached to the slot. In order to form a drive between the crank axis pin and the drive shaft cavity and where the axial length channel allows the chain wheel to be shifted relative to the axis The crank between the held position and the working position on the chainwheel is adjusted to be fixed by the bicycle chain. To drive the bicycle chain, the bicycle chain sends The force to the crank axis increases rotation. And therefore causing the piston to slide along that Inside the cylinder hole to inflate air through the outlet of the cylinder 2. The bellows according to claim 2, with the outer end of the drive shaft arranged. With a thread where the female nut was attached To attach the chain wheel to the outer end of the drive shaft. 3. The bellows according to claim 1, where the crank axis consists of a long axis that There is a first end and a second end, one end the rod is threaded, the arm with a hole is inserted on it. The first end, and fixed there by means of a female nut to fix the thread of the first end sleeve with eccentric pins Supported to be rotated in a hole created on the connecting rod 4. The bellows according to claim 3, where the cylinders are arranged by a support hole with a long protruding axis. And where the long rod has a thread on its second end that is secured with a female nut to attach the long rod to the cylinder in a way that allows the long rod to rotate inside the cylinder hole. 5. The bellows according to claim 1, which consists of a pressure gauge that is connected at Cylinder outlet 6. The bellows according to claim 1, which are followed by a protective cover for the crankcase and connecting rods. 7. The bellows, according to claim 1, are connected with flexible pipes that can be connected to Adjusted cylinder exit So that the wind being pumped to something like wind 8. The bellows according to claim 1, which follows the protective shield parts. Chain wheel at the stowed position
