Abstract

The utility model relates to a hand-press pump for drawing underground water, which is composed of a pump base, a pump cylinder, a pump cover, a rocker, a connecting rod, a piston assembly, a lower forbidden water valve, etc., wherein, the pump cylinder is a T shape, the rocker is a half arc shape, and the piston parts adopts aluminum alloy die casting parts. The utility model has the advantages of no overflow and leakage, small occupying space, convenient replacement of wearing parts and long life, and the utility model is mainly used for drawing the underground water by hands.

Description

Hand-press pump for drawing water

The utility model relates to a kind of underground craft apparatus that draws water.

Hand suction pump of the prior art though can draw water from underground, has the function of drawing water, but because its unreasonable structure exists easy spill and leakage when drawing water, rocking bar takes up space more at ordinary times, and part such as piston assembly easily gets rusty, and easily damaged parts is changed shortcomings such as inconvenience, thereby influences usability.

It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and can overcome the hand suction pump of above-mentioned shortcoming, makes its not spill and leakage, and duty is little, and easily damaged parts is changed convenient, and durable, the efficient height has better practicability.

The utility model, form by pump seat, pumping cylinder, pump cover, rocking bar, connecting rod, piston assembly and following taboo water valve etc., pumping cylinder is installed on the pump seat by packing ring, one inlet valve is arranged on the pump seat, one lock screw is arranged on the pump cover, pump cover can be locked on the pumping cylinder, also has a supporting base A on the pump cover, rocking bar is bearing on this seat, and by connecting rod connection piston assembly, it is characterized by: piston assembly is made up of piston seat, rubber piston, locking nut and the last water valve of prohibiting, and locking nut and piston seat are aluminum alloy die casting, non-corrosive, it is convenient to change rubber piston; It is "T"-shaped that pumping cylinder is, and its first half makes water not excessive as reservoir, and has water outlet in the one side, and water outlet is a tubulose; Rocking bar is half arc, and when water pump was not worked, rocking bar vertically near the pump housing, took up space less.

The utility model can also be made " returning " shape with the packing ring and the following taboo water valve pad of pump seat and pumping cylinder joint, closes two and is one, and its outer ring is as connecting packing ring, and intermediate portion is following taboo water valve pad.

The utility model compared with the prior art, has when using not spill and leakage, and rocking bar takes up space less at ordinary times, the piston assembly non-corrosive, and easily damaged parts is changed convenient, and good seal performance is durable, characteristics such as efficient height, it will be the update product of existing product.

Following embodiment will be described further in conjunction with the accompanying drawings:

Fig. 1 is the utility model assembling schematic representation, and Fig. 2 is following taboo water valve packing ring sectional view.

Among the figure, taboo water valve, (9) piston seat, (10) pump cover, (11) connecting rod are gone up in taboo water valve, (4) pumping cylinder, (5) rocking bar, (6) lock piston jack panel, (7) rubber piston, (8) down for (1) pump seat, (2) following taboo water valve packing ring, (3).

The following taboo water valve packing ring of present embodiment, piston adopt rubber material to make, and lock piston jack panel and piston seat process after with aluminium alloy compression casting, and all the other component carry out surface Machining after adopting iron castings, with link each parts are assembled again.

Claims

1, a kind of hand suction pump, form by pump seat, pumping cylinder, pump cover, rocking bar, connecting rod, piston assembly and following taboo water valve etc., pumping cylinder is installed on the pump seat by packing ring, one inlet valve is arranged on the pump seat, pump cover is bowl-type, one lock screw is arranged on its limit, pump cover can be locked on the pumping cylinder, also has a supporting base on the pump cover, rocking bar is bearing on this seat, and by connecting rod connection piston assembly, it is characterized by: piston assembly is made up of piston seat, rubber piston, locking nut and the last water valve of prohibiting, and locking nut and piston seat are aluminum alloy die casting; It is "T"-shaped that pumping cylinder is, and its first half is as reservoir, and have water outlet in the one side, and water outlet is a tubulose; Rocking bar is half arc, and when water pump was not worked, rocking bar vertically near the pump housing, took up space less.

2, hand suction pump according to claim 1 is characterized by: there is taboo water valve packing ring under one " returning " shape pump seat and pumping cylinder joint, and its outer ring is as the be connected packing ring of pump seat with pumping cylinder, and the intermediate portion conduct is the pad of taboo water valve down.
