Abstract

The utility model provides a handle rocking pump for the liquid pump field. The utility model is mainly characterized in that a hydraulic cylinder is divided into a hydraulic cylinder at the left side of a piston and a hydraulic cylinder at the right side of the piston; two sets of water inlet valves and water outlet valves are arranged above the hydraulic cylinder in parallel; a lower water inlet chamber is communicated with an upper water inlet chamber by a water inlet passage; the piston non-intermittently reciprocates with alternate actions of left/right water inlet valve and left/right water outlet valve. The utility model can implement continuously providing water, improves the water supply efficiency, and is suitable for filling liquids such as lubricants, fuel oils, water, etc. to vehicles, ships, oil tanks, water tanks in the field without a power supply.

Description

Manual pump

Technical field

The utility model belongs to the liquid sorption pump field, relates to a kind of single cylinder hand piston pump, is specifically related to a kind of manual pump of single-cylinder dual-action.

Background technique

Existing single cylinder hand piston pump generally comprises the pump housing, piston, a cover inlet valve and an outlet valve, the water inlet elbow, water exit elbow, handle is connected with piston rod by handlebar, form single cylinder list running way of supplying water, exist to be interrupted and supply water the defective that water application efficiency is low.

The model utility content

The claimant organizes the present situation process investigation of designer to existing manual single cylinder piston pump, finds to exist certain defective, and purpose is to provide a kind of novel manual pump, and this manual pump can uninterruptedly supply water in the two runnings of single cylinder, improves water application efficiencies.

For realizing above-mentioned task, technical solution adopted in the utility model is a kind of manual pump of design, its structure comprises: the pump housing, piston, fluid cylinder is divided into piston left side fluid cylinder and piston right side fluid cylinder, above fluid cylinder and establish left side cover inlet valve and outlet valve and right cover inlet valve and outlet valve, the water inlet elbow is located at pump housing below, following water-inlet cavity is communicated with last water-inlet cavity by intake tunnel, last water-inlet cavity and left and right sides inlet valve are connected mutually, offer outlet valve on the fluid cylinder wall, handle is connected with the crank-connecting rod of piston by handlebar.

In order to reduce the requirement on machining accuracy of piston assembly, increase the service life, piston employing piston rises to encircle and contacts with piston cylinder, and the piston crank connecting rod adopts ball head connecting rod to be connected with piston.

This manual pump of the present utility model compared with prior art, has following remarkable advantage:

1, since adopt left and right sides biliquid cylinder and about two cover inlet valves and outlet valves, when piston not intermittently during to-and-fro motion, left and right sides inlet valve, outlet valve alternating movement can realize uninterrupted continuous water supply, have improved water application efficiency.

2, ring and ball head connecting rod because the employing piston rises, to the precision prescribed reduction of piston assembly, prolong working life.

3, owing on the fluid cylinder wall, offer outlet valve, can get rid of air in the fluid cylinder, avoid vapour lock and empty row, improve quality of water supply and efficient.

Description of drawings

Fig. 1 represents that the hand pump structure master of the utility model looks schematic representation.

Fig. 2 represents the utility model structure cross-sectional schematic.

Embodiment

In conjunction with the accompanying drawings and embodiments, further specify the concrete structure of the utility model manual pump, its feature and advantage can be clearer.

The embodiment 1 of the utility model manual pump, referring to Fig. 1, Fig. 2, its structure comprises: the pump housing 5, piston 9, left side fluid cylinder 10, right side fluid cylinder 16, above fluid cylinder and be provided with left inlet valve 8, left side outlet valve 7 and right inlet valve 13, right outlet valve 12, water valve adopts safety check, water inlet elbow 3 is located at the pump housing 5 belows, following water-inlet cavity 19 is communicated with last water-inlet cavity 14 by intake tunnel 4 (referring to Fig. 1), last water-inlet cavity 14 and left inlet valve 8, right inlet valve 13 is connected mutually, and water exit elbow 6 is located at left outlet valve 7, right outlet valve 12 tops are also connected mutually, handle 1 is connected with the crank-connecting rod 15 of piston by handlebar 2, also offers outlet valve 17 on the casing wall of right side fluid cylinder 16.

The embodiment 2 of the utility model manual pump, referring to Fig. 2, its structure comprises: in embodiment 1 structure, wherein piston 9 adopts rise ring 11 of pistons to contact with piston cylinder.

The embodiment 3 of the utility model manual pump, referring to Fig. 2, its structure comprises: in the structure of embodiment 1 or 2, wherein crank-connecting rod 15 adopts ball head connecting rod 18 to be connected with piston 9.

The utility model manual pump with hand active handle 1, drives action such as piston crank connecting rod 15 parts such as grade by handlebar 2 in use, makes piston 9 make transverse reciprocating motion.When piston 9 (right side) motion left, right (left side) side fluid cylinder 16 (10) volumes increase, and liquid (water) is opened the right side (left side) inlet valve 13 (8) through intake tunnel 4, enters the right side (left side) side fluid cylinder; At this moment, a left side (right side) side fluid cylinder is compressed, and a left side (right side) outlet valve 7 (12) is opened, and liquid (water) is discharged through water exit elbow 6.Piston about 9 continuous to-and-fro motion, left and right sides outlet valve 7,12 is alternately opened, thereby realizes the uninterrupted continuous water supply of two runnings.

The utility model manual pump is applicable under the open-air non-transformer condition to vehicle, boats and ships, fuel tank, water tank filling lubricant oil, liquid such as fuel oil, water.
