Abstract

The utility model discloses a piston type double-passage hand operated pump, consisting of a cylinder body, a piston, two groups of in-taking and out-taking valves which cooperate with each other, a sealing ring of the cylinder body, a hand operated rocking handle and a rocking handle support which both have circular arc teeth. When the rocking handle moves up and down, the front end of the rocking handle drives the piston connecting bar, which makes the piston move up and down. Under the pressure of the piston, one group of the two groups of valve balls are closed and the other are opened. The upper and the lower parts of the piston which are in the cylinder body are always in the water in-taking and out-taking status so as to guarantee the continuous in-taking and out-taking work of the water inlet and outlet when the piston moves up and down. The rocking handle support with circular arc teeth controls the upward and downward movement of the rocking handle and the piston connecting bar is always in the up and down vertical movement. Thanks to the adoption of the above structure, the working efficiency of the pump is improved, the mounting and repair are facilitated and water conveying across a certain distance and height is achieved.

Description

Piston type round trip hand water pump

Technical field

The present invention relates to a kind of piston type round trip hand water pump that draws water, it comprises cylinder body, piston, manual rocking handle and rocking handle support composition.

Background technique

In the market, at a kind of hand water pump of rural area use, it is made up of cylinder piston and manual rocking handle especially.Because what its piston adopted is that one way is advanced, water outlet; rocking handle fluctuates once; just can finish once; water outlet stroke; so very time-consuming and manpower; its rocking handle is arranged again and the rocking handle support adopts is the rotation of fixing; when rocking handle moves up and down; the rocking handle front end drives piston rod and moves up and down; because the rocking handle front end is to do circular motion with the fixing pin of rocking handle so piston rod will swing, thereby causes that piston tilts forward and back motion in cylinder body; cause the piston seal reduction; ring wear is fast, cause the working efficiency reduction, shortcomings such as easy damage.

Summary of the invention

The present invention is on the basis of the above, provides a kind of both laborsaving, can raise the efficiency again, reduces wear, can also certain distance and the piston type round trip hand water pump of height water delivery.

In order to achieve the above object, the invention provides a kind of piston type round trip hand water pump with following structure.This water pump comprises the manual rocking handle of cylinder body, piston, cylinder cap, piston rod, band circle-arc tooth and the rocking handle support of band circle-arc tooth, and two groups of water inlet and outlet valve balls that cooperatively interact are formed.When the rocking handle rear end moves up and down; intermeshing a pair of tooth is done the circular arc displacement on rocking handle and the rocking handle support; guarantee that piston rod does not tilt forward and back; two clamping plate have been installed in the both sides of round-arced tooth on the rocking handle support; guarantee that piston rod do not vacillate now to the left, now to the right; on rocking handle and rocking handle support; do not blocked when guaranteeing that rocking handle moves as circular arc on the rocking handle support; on the two clamping plates of rocking handle support by pin for guaranteeing that rocking handle is when moving up and down; two round-arced tooths do not separate; a pin has been installed, opened one poor with knuckle-tooth with the pin of circular arc, pin can be moved as circular arc in being pickled with grains or in wine.

When rocking handle moved up, the rocking handle front end drives piston rod moved down piston.At this moment, the effect that is stressed, following water outlet valve ball and last inlet valve ball are opened, and upper water-out valve ball and following inlet valve are closed, and finish the water-in and water-out stroke one time.Otherwise when rocking handle moved down, the rocking handle front end drives piston rod moved up piston, and under the effect of pressure, the upper water-out valve ball and the valve ball of intaking are down opened, and following water outlet valve ball and last inlet valve ball are closed, fully again the water inlet and outlet stroke.For ease of installing, stay one and cylinder body recessed being pickled with grains or in wine of the same size in the cylinder body lower end, be convenient to be contained in Lower Half and enter on the underground timber.

Description of drawings

Fig. 1 is one embodiment of the present invention positive views.

Fig. 2 is the right sectional view of mode of execution cylinder body shown in Figure 1.

Fig. 3 is the right sectional view of rocking handle support shown in Figure 1.

Embodiment

At first referring to Fig. 1, this piston type round trip hand water pump mainly is made up of the two large divisions.One is that 2 liang of groups of cylinder body 1, piston water inlet and outlet valve ball (21,19,18,20), cylinder cap 3, the connecting rod 10 of implementing the water inlet and outlet stroke formed.A manual rocking handle 17 and a rocking handle support 11 that is moved up and down by driven plunger 2 is formed.When rocking handle 17 moves down, rocking bar front end 16 serves as that axle moves upward with rocking handle pin 27, at this moment piston rod 10 is done vertical motion; the one group of circle-arc tooth (13,12) on rocking handle 17 and the rocking handle support 11 is done to the right and rocking handle front end 16 moving with circular arc; the two clamping plates on the rocking handle support 11 (14,14 ') control rocking handle 17 does not swing; can do circular motion with rocking handle 17 for guaranteeing rocking handle pin 27; on the two clamping plates (14,14 ') of rocking handle support 11; pin of respectively having opened a circular arc is pickled with grains or in wine 15, guarantees upwards vertical movement of connecting rod 10 works like this.When connecting rod 10 moves up, piston 2 is upwards mentioned, this moment under pressure, water inlet valve ball 19 is upspring, water enters the cylinder body Lower Half from water intake 25 through cylinder body water intake 8, water outlet valve ball 21 is upspring, and to water outlet 24 water outlets, water inlet valve ball 18 and the following water outlet valve ball 20 on the cylinder body 1 is in closed condition to the water of cylinder body 1 first half at this moment through cylinder body water outlet 22.

When rocking handle 17 upwards shakes; rocking handle front end 16 is under the drive of pin 26; make piston rod 10 drive pistons 2 and move down; this moment, water inlet valve ball 18 was upspring under pressure, and water enters cylinder body 1 first half from water intake 25 through cylinder body water intake 23; water outlet valve ball 20 is upspring; water from cylinder body 1 Lower Half through the cylinder body mouth of a river 7 from water outlet 24 water outlets, water inlet valve ball 19 and water outlet valve ball 21 are in closed condition, finish continual water inlet and outlet stroke up and down this moment.In order to guarantee sealing effect, a rubber seal 4 is installed on piston 2, a cylinder cap 3 and seal ring 5 are installed on cylinder body 1 top, in connecting rod 10 and cylinder cap 3 contacting points a rubber seal 6 is installed.

For ease of installing, the lower curtate of cylinder body 1 leave one recessed poor 9 with cylinder body 1 circle of the same size, for being assemblied on the buried timber of Lower Half.

The present invention is not limited to the mode of execution that draws water, and all liq is had effect same, for those of ordinary skill in the art, manual rocking handle partial reequipping can also be become improvement electronic or that other form drives, all belongs to protection scope of the present invention.
