Abstract

The invention discloses a hand pump convenient to adjust output efficiency. The hand pump comprises a water pumping well base, a water suction pump base is connected to the water pumping well base, a pump body is arranged at the top end of the water suction pump base, a T-shaped lifting rod is arranged at the top end of the pump body, and a check valve plate and a leather cup movable valve are arranged in the pump body. By arranging the main gear, the large-size gear and the small-size gear, during use, an auxiliary rotating rod which penetrates through the small-size gear or the large-size gear in a sleeving mode is driven, the auxiliary rotating rod is driven to rotate back and forth through a fixing block, and the small-size gear or the large-size gear drives the main gear to rotate back and forth to pump water; due to the fact that the number of teeth of the small gear is smaller than that of teeth of the large gear, when the rotation angles of the small gear and the large gear are the same, the rotation angle of the main gear driven by the small gear is smaller than that of the large gear, the up-down amplitude of the leather cup movable valve is reduced, the output efficiency is reduced, and the burden of arms is greatly reduced. And a user can select according to own conditions.

Description

technical field [0001] The invention relates to the technical field of hand pump design, in particular to a hand pump that is convenient for adjusting output efficiency. Background technique [0002] The hand pump is suitable for pumping clean water, gasoline, kerosene and non-corrosive liquids such as iron and copper. It is not suitable for liquids containing fibers or other solid particles. It only needs 1 to 2 people to shake the handle back and forth by hand. Work, can be used by industrial and mining, enterprises, schools, vehicles, ships and other units. When pumping well water, the hand pump is usually placed on the well seat for pumping. [0003] The current hand pump cannot adjust the output efficiency. It is difficult for people with poor physical strength to use it, which may easily cause arm pain and low applicability. Therefore, it is necessary to design a hand pump that is easy to adjust the output efficiency. Contents of the invention [0004] The purpose o...
