Abstract

The utility model relates to a transport vehicle fueling tool, which is designed into a one-way valve-body-type mechanical vacuum-pumping oil-pumping device by the vacuum siphon principle. The transport vehicle fueling tool is mainly composed of a cylinder, a piston, a valve body and a cock, wherein, the inside of a middle slot of the piston thereof is sheathed with a sealing ring and the valve body; the inner cavity is provided with a spring and a steel ball; the air in an oil-pumping pipeline is expelled through the cylinder; the cock is opened to pump oil. The oil-pumping device, which has simple structure, convenient assembly and disassembly, small size, low price and durability, is an ideal tool for a transport vehicle to be fueled or other industries to pump liquid substance.

Description

Transport vehicle fuel charger

The utility model belongs to instrument category, is particularly suitable for the haulage vehicle oiling and uses.

Usually during the driver drives the way of travelling of highway in the open air, all in deposit big oil drum onboard, in the fuel tank of vehicle, refuel,, not have appropriate instrument again, suck the way that plastic tube aspirates so often adopt because of can not directly pouring into.This method is no doubt feasible, but as suction control improper, fluid be inhaled in the body with regard to regular meeting or be sprayed onto on the face, on one's body, not only operation inconvenience wastes energy, but also harmful health, so presses for and seek a kind of fueling vehicle.Recently, occurred rubber ball exhaust oil-sucker on the market, but through facts have proved, this oil-sucker working efficiency is lower and be easy to damage, so can not can be regarded as the ideal tools of suction oil.

The utility model adopts siphon principle equally, designs a kind of pumping tool of armstrong's patent formula, can reach good suction effect, and sanitation and hygiene are easy to use.

Technical solution of the present utility model is shown in the accompanying drawing that provides.

Accompanying drawing 1 is a structural representation of the present utility model.

Among the figure: 1 for valve body, 2 for cock, 3 for upper cover, 4 for cylinder, 5 for pull bar, 6 for handle, 7 for lower seal head, 8 for piston, 9 for the O RunddichtringO, 10 for the rectangular seal packing ring, 11 for attachment screw, 12 for spring, 13 for steel ball, I be that fuel sucking pipe import, II are that fuel sucking pipe outlet, III are fuel tank.

Now further narrate by reference to the accompanying drawings technical characterictic of the present utility model.

The utility model mainly is made up of cylinder 4, piston 8, valve body 1, cock 2 several parts. Piston 8 is installed in the cylinder 4, have medial launder at its periphery, make piston be up and down round shape book sheet, middle folder diameter is than little, the nahlock that thickness is more big, the axis of the piston is " worker " shape to the cross section, the medial launder inner sleeve that is furnished with to impartial position several circular holes, piston on the lower circle sheet ring of piston has O RunddichtringO 9; Valve body 1 is connected, leaves in the middle of the attachment screw (11) circular hole and littler as the contained Circular Aperture of its base by connected nail 11 with cylinder, and bigger as the contained Circular Aperture of ledge of " nail ". This circular hole cylinder communicates with the inner chamber of valve body. In addition, the ledge of attachment screw 11 has male thread to screw in body cavity, places in the chamber in the circular hole of spring 12 and located attachment screw, and there is steel ball 13 on the top on the spring. The inner chamber footpath of locating valve body on the steel ball dwindles suddenly, and steel ball must not be passed through. Lumen leads to fuel sucking pipe import I, outlet II. The fuel sucking pipe that cock 2 is installed in valve body exports a side. The two ends of cylinder 4 are rotary with upper cover 3, low head 7. In the attachment screw 11 base position cylinders, upper cover 3 and be lined with rectangular seal packing ring 10, also stay several circular holes on the disc of low head 7. Pull bar 5 one ends stretch into that cylinder is vertical to be connected with piston, and cylinder outer and handle in other end position joins.

The utility model can come into operation after finishing with above-mentioned feature description assembling with reference to the accompanying drawings.The flexible pipe that will be enclosed within fuel sucking pipe import, outlet before using inserts in the fuel tank of big oil drum and vehicle, stir cock 2 during use and become 90 ° (exporting obstructed) with valve body fuel sucking pipe Way out, hold cylinder, twitch a position hand 6 continuously up and down, that pull bar 5 drives pistons is reciprocating in cylinder.Air in the fuel sucking pipe inlet hose, because the compression of spring, steel ball become flexible, just enter body cavity, intermediate hole by attachment screw 11 is to cylinder, gap by circle shape sheet and cylinder inner wall on the piston enters middle groove again, reenter down the small sircle hole of disk and the circular hole of lower seal head, discharge outside the cylinder.Because the air in the effect of O RunddichtringO, cylinder can not enter body cavity.When the fuel sucking pipe inlet hose was in vacuum, fluid just entered fuel sucking pipe.Needn't twitch handle again this moment, opens cock, steel ball is withstood by spring, and fluid must not enter cylinder, flows into fuel tank just unobstructedly.When no longer refueling, stir cock blocking-up oil circuit, excess oil returns big oil drum.Adopt anticorrosive material to make as the utility model, also can be used for extracting other acid-base class liquid.

To sum up, the utlity model has simple in structure.Suction effect is good, installs and removes advantages such as convenient, that volume is little (long only 6-7 cun), price is low, durable, is the ideal tool that haulage vehicle refueled and extracted other liquid substance.
