Problems solved by technology

When pumping air into the tire, the valve is closed by the air pressure in the air cylinder, and the gas enters the tire, which can be regarded as using the principle of atmospheric pressure to inflate. However, some existing automobile tire air pumps have simple structure and single function. The air pressure does not have a good control and adjustment function, resulting in unstable air pressure, damage to the tire, and affecting the service life of the tire
At the same time, the motor needs electricity to run, so this kind of car air pump is not suitable for outdoor use

Abstract

The invention relates to a mechanical-type speed regulating air pump. The mechanical-type speed regulating air pump is characterized by comprising a driving device, a speed regulating device and an air supplying device. The speed regulating device comprises a speed regulating device shell, a one-way clutch, a sun gear, planet pinions, a planet frame, a gear ring, a gear ring brake belt, a cam plate driving shaft and a cam plate. The sun gear, the planet pinions, the planet frame and the gear ring form a planet gear mechanism. The one-way clutch is connected with the output ends of the sun gear and the driving device. The mechanical-type speed regulating air pump does not need to be driven by a motor. A mechanical-type air inflation pump is formed by a series of mechanical mechanisms. A tyre can be inflated only through treading of a foot treadle by labor, so that the problem that a motor type air inflation pump cannot be used outdoors is solved. Two speeds can be adjusted when air inflation is conducted through the mechanical-type speed regulating air pump, the air inflation speed is high, air flow is free from fluctuating at the time of air inflating, high adaptability is achieved, and meanwhile, air displacement is large.

Description

technical field [0001] The invention relates to a mechanical speed regulating air pump. Background technique [0002] Car air pumps are also called inflators, air pumps, and car air pumps. They generally work through the operation of an internal motor. When pumping air into the tire, the valve is closed by the air pressure in the air cylinder, and the gas enters the tire, which can be regarded as using the principle of atmospheric pressure to inflate. However, some existing automobile tire air pumps have simple structure and single function. The air pressure does not have a good control and adjustment function, resulting in unstable air pressure, damage to the tire, and affecting the service life of the tire. At the same time, electric power is needed for the operation of the motor, so this vehicle air pump is not suitable for outdoor use. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present invention is to propos...
