Description

Meter for oil filling of oil tank

The utility model relates to a kind of measuring apparatus, particularly a kind of measuring apparatus of metering liquid flow.

A few days ago, on oil tanks such as motor vehicle, power ship, all do not measure the measuring apparatus of oil inlet quantity, when the driver refuels to the refuelling station, can't know whether enough amount of institute's volume read-out, especially at present highway is gone up individual refuelling station along the line and is thick on the ground, the time have the phenomenon of embezzling part of what should be issued institute's bunkering of fuel to take place, bring loss to unit or driver.

The purpose of this utility model is exactly in order to address the above problem, and provides a kind of and can show the fuel tank inlet metering table that adds oil mass in the fuel tank.

Technical solution of the present utility model:

A kind of fuel tank inlet metering table, it includes housing (1), impeller box (2), impeller assembly (3), last magnetic support (4), gear set (5) and surface plate (6), wherein impeller assembly (3) is by impeller (7), impeller shaft (8), following magnetic support (9) is formed, it is positioned at impeller box (2), gear set (5) is fixed on, lower plate (10), (11) between, surface plate (6) is provided with a plurality of decimal display discs (12), the pointer (13) of each display disc (12) is connected with last magnetic support (4) by gear set (5), it is characterized in that this gauging table is positioned at the neck of fuel tank oil-in, in a side of housing (1), be provided with oil inlet passage (14), and the bottom of this oil inlet passage (14) is communicated with impeller box (2) bottom, the position of corresponding impeller box (2) the top oil outlet in housing (1) bottom (15), on the outer wall of its non-oil inlet passage (14), have oil-out (16), make that the oil in the impeller box (2) flows into fuel tank by circular passage (17) from oil-out (16).

The utility model organically is connected as a single entity flowmeter and oil box, makes that flowmeter indicated institute's volume read-out synchronously, can effectively prevent the inenough phenomenons of refuelling station institute volume read-out when fuel tank refueled.The utility model is simple in structure, and is easy for installation, and the normal use of fuel tank is had no effect.

Fig. 1 is a cross-sectional view of the present utility model;

Fig. 2 is the A-A direction cut-open view of Fig. 1;

Fig. 3 is an outside drawing of the present utility model.

As Fig. 1,2, housing of the present utility model (1) lower outer diameter and fuel tank eck internal diameter match, and the overhanging upper port that hangs over the fuel tank eck in housing (1) limit (18), upper end, and making them is an integral body.Housing (1) limit, upper end (18) can be not overhanging yet, and it is stuck on the convex tendon of fuel tank eck upper inside wall.Because housing (1) lower outer diameter and fuel tank eck internal diameter match, then should be in the vertical line direction of oil inlet passage (14) with surface plate (6) center line line, housing (1) bottom two arc outer walls are inwardly shunk formation two planar walls (19), two oil-outs (16) are just opened on two planar walls (19) tops (as Fig. 3), leave spacing between the planar wall (19) of housing (1) and the fuel tank eck inwall like this, guarantee that oil flows into fuel tank smoothly.

During the utility model work, the oil gun of refuelling station is inserted the suitable for reading of the interior oil inlet passage (14) of housing (1) one side, refuel then, oil flows to by the bottom of oil inlet passage (14) from impeller box (2), promote impeller (7) rotation of impeller assembly (3), impeller (7) rotates by impeller shaft (8) and drives magnetic support (9) rotation down.Following magnetic support (9) rotates magnetic support (4) by its magnetic force again, last magnetic support (4) makes the pointer (13) of the corresponding display disc (12) on the surface plate (6) rotate indication by gear set (5) again, demonstrate the value that refuels, each display disc (12) rotates demonstration successively by individual, ten, hundred order, the pointer (13) of each display disc (12) is connected with reset key (21) by mechanical component and cam (20), and its structure is similar to the stopwatch resetting-mechanism.Before each the oiling, should click reset key (21), each pointer (13) is all referred to above freezing, and then Fuel-filling metering.Oil in the inflow impeller box (2) portion's oil outlet (15) stream from it goes out together, flow into fuel tank by circular passage (17) oil-out (16) through housing (1), when oiling finishes, the driver only need have a look the display disc of the present utility model (12) on the fuel tank eck, just can accurately know add oil oil mass, prevent that other people embezzle part of what should be issued institute's bunkering of fuel.

Claims (2)

1, a kind of fuel tank inlet metering table, it includes housing (1), impeller box (2), impeller assembly (3), last magnetic support (4), gear set (5) and surface plate (6), wherein impeller assembly (3) is by impeller (7), impeller shaft (8), following magnetic support (9) is formed, it is positioned at impeller box (2), gear set (5) is fixed on, lower plate (10), (11) between, surface plate (6) is provided with a plurality of decimal display discs (12), the pointer (13) of each display disc (12) is connected with last magnetic support (4) by gear set (5), it is characterized in that this gauging table is positioned at the neck of fuel tank oil-in, in a side of housing (1), be provided with oil inlet passage (14), and the bottom of this oil inlet passage (14) is communicated with impeller box (2) bottom, the position of corresponding impeller box (2) the top oil outlet in housing (1) bottom (15), on the outer wall of its non-oil inlet passage (14), have oil-out (16), make that the oil in the impeller box (2) flows into fuel tank by circular passage (17) from oil-out (16).

2, by the described fuel tank inlet metering of claim 1 table, it is characterized in that housing (1) lower outer diameter and fuel tank eck internal diameter match, and the overhanging upper port that hangs over the fuel tank eck in housing (1) limit (18), upper end, making them is an integral body; Correspondingly, in the vertical line direction of oil inlet passage (14) with surface plate (6) center line line, housing (1) bottom two arc outer walls are inwardly shunk formation two planar walls (19), two oil-outs (16) are just opened on two planar walls (19) top.
