The utility model relates to an air pump

There are two main types of existing inflators: single cylinder and multi cylinder. For a single cylinder, use the cylinder to relieve the exhaust pressure or reduce the section to increase the pressure. The electronics are limited by physical strength and cannot increase the cylinder exhaust pressure. The latter sacrifices the intake. Therefore, a single cylinder pushes a two-way air tank. The concealed two-way air compressor, which can double the exhaust pressure when the breathing volume is unchanged, is an accompanying tool for bicycles.

The utility model relates to a high-pressure two-way air pump, which has two steel cylinders in a plurality of barrels. Pull the handle, two steel cylinders inhale at the same time, push the handle, and two steel cylinders discharge at the same time. It is still a one-way operation, and the suction volume and expansion pressure will not increase at the same time. There is a pedal platform in parallel with a high-pressure pump, which is a set of six tubes and three tubes in parallel. It is complex in structure, high in cost, and should not be popularized.

The utility model aims to provide a high-pressure inflator with simple structure, large breathing capacity and high exhaust pressure.

The utility model provides a two-way high-pressure inflator, which has the size of two cylinders, two pistons matched with them, the size of the straight butt joint of two cylinders, and an o-type one-way valve at the butt joint position. The valve is firmly clamped to the connecting rod between the two pistons. The connecting rod can slide back and forth on the round hole of the o valve. The small piston is fixed at the bottom of the connecting rod, the large piston is fixed in the middle, and the top is connected to the handle. The large and small pistons are unidirectional.

The o-valve is sealed with a seal and a seal seal respectively between the cylinder and the cylinder, the small cylinder is sealed with the bottom cover, the bottom cover is sealed with the bottom cover, the cylinder is connected with the top cover wire port, the piston connecting rod is connected with the handle wire port, the external steel cylinder is fixed on the base with a profiled plate and two bolts, and the base and the steel cylinder are sealed with a seal seal. The base is also provided with an air outlet connecting the air pipe and a shaft hole of the springboard.

combination

The working principle of the utility model is to pull the handle, open the valve, close the O-ring valve and valve, then open the suction valve, inhale the cylinder and cylinder at the same time, compress the small cylinder and then the pressure gas, discharge the compressed air into the air chamber through the exhaust valve, discharge the compressed air through the air hole and air, complete the inflation, and push the handle, valve and valve.

The round-trip operation of the utility model adopts secondary compression, has large suction volume, high exhaust pressure, labor saving, time saving and high efficiency. The expansion pressure is between 0.4 MPa and 1.8 MPa, which can meet the inflation of various vehicle tires and other inflators.

Requirements for main, base, small cylinder bottom cover, piston connecting rod, sealing ring (gasket), outer steel pipe, sealing ring (gasket), small cylinder, sealing ring (gasket), large cylinder, sealing ring (gasket), valve, sealing ring (gasket).

The utility model relates to a high-pressure two-way inflator, which comprises two cylinders of the same size and two corresponding pistons, and is characterized in that two cylinders of the same size are simply connected by wires. The butt joint part has an o-type check valve. The valve is firmly clamped to the connecting rod between the two pistons. The connecting rod can slide back and forth on the round hole in the middle of the o-valve. The small piston is fixed at the bottom of the connecting rod, the large piston is fixed in the middle, and the top is connected to the handle. There is one piston for each of the two pistons.

The high-pressure two-way inflator is composed of two cylinders and two matching pistons. The two cylinders are connected by an O-ring check valve. The O-ring valve is firmly clamped on the connecting rod between the two pistons. The upper, middle and lower parts of the connecting rod respectively fix the handle, large piston and small piston. The two pistons each have a check valve. The small cylinder has a suction valve at the bottom, and an exhaust valve on the upper side wall. Pull the two cylinders on the handle to inhale at the same time. The pump has the advantages of high pressure, efficiency and labor saving, and is suitable for inflating tires of various vehicles.
