A drive device for a mechanical air pump

Abstract

The invention relates to a driving device of a mechanical air pump. The driving device of the mechanical air pump is characterized by comprising a driving mechanism and a speed adjusting mechanism; the driving mechanism comprises a driving mechanism outer shell, a slide rod, a rack, a gear shaft and a pedal plate; the driving mechanism is connected with an one-way clutch through the gear shaft and the speed adjusting mechanism; the upper ends of the slide rod and the rack are both connected with the pedal plate; and the driving mechanism outer shell is provided with a guide rail, the slide rod is slidably matched with the guide rail, and a reset spring is connected between the slide rod and the driving mechanism outer shell. According to the driving device of the mechanical air pump, though a series of mechanical mechanisms, a device capable of providing stable driving force for a tire inflating device is designed; and a user can provide the driving force for the tire inflating device by stepping the pedal plate, and the problem that a motor-type inflator pump cannot be used outdoors is solved.

Description

technical field [0001] The invention relates to a driving device of a mechanical 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 pumps have simple structure and single function. The tire 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] In view of the problems existing in the prior art, the object of the present invention is to provi...

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 pumps have simple structure and single function. The tire 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
