Abstract
The utility model relates to a mounting structure of fuel tank and oil pump, its on having the fuel tank of trompil box, the mounting flange who fixes in the trompil periphery and with trompil complex oil pump ring flange, in the trompil of box on the fuel tank was installed to the oil pump ring flange, the box was provided with first sealing washer on oil pump ring flange and the fuel tank, the radial extension formed the scrap (bridge) after the edge part of oil pump ring flange upwards extended mounting flange's centre bore, and scrap (bridge) and mounting flange's terminal surface is provided with the second sealing washer, mounting flange threaded connection has pair blind flange that the downward pressure was applyed to the oil pump ring flange. The utility model provides a sealed problem of fuel tank and oil pump installation.
Description
Technical field
This utility model belongs to the mounting structure of automotive fuel oil system field, a kind of fuel tank and oil pump.
Background technology
Fuel tank has with the installation component part of oil pump at present: oil pump mounting flange, sealing ring, fuel pump, oil pump mounting flange lid and the bolt welded on fuel tank, fuel tank.When oil pump is installed, sealing ring is inserted in oil pump, by oil pump mounting flange, oil pump is loaded fuel tank.Sealing ring is arranged between oil pump and fuel tank, is compressed with fuel tank by oil pump by oil pump mounting flange lid, makes sealing ring be in compressive state, it is ensured that oil pump and the sealing of fuel tank；With bolt, oil pump mounting flange lid is fixed with oil pump mounting flange, it is ensured that fixation.Car load discharge vaporization is required increasingly stricter by regulation at present, requires higher to fuel tank with the fuel-steam infiltration capacity of oil pump installation place, the sealing of above-mentioned mounting structure is proposed baptism, is badly in need of the mounting structure that a kind of sealing is more excellent.
Summary of the invention
The purpose of this utility model is the mounting structure providing a kind of fuel tank with oil pump, and it can solve the problem that the sealing problem that fuel tank is installed with oil pump.
The technical solution of the utility model is as follows:
A kind of fuel tank and the mounting structure of oil pump, it includes having the fuel tank upper box of perforate, the mounting flange being fixed on perforate periphery and the oil pump flange plate coordinated with perforate, oil pump flange plate is arranged in the perforate of fuel tank upper box, is provided with the first sealing ring between oil pump flange plate and fuel tank upper box；The edge part of oil pump flange plate radially extends after extending upward the centre bore of mounting flange and is provided with the second sealing ring between the end face of formation scrap (bridge), scrap (bridge) and mounting flange；Mounting flange is threaded the blind flange that oil pump flange plate applies downward pressure.
Further, fuel tank upper box is provided with the U-lag of indent, and the first sealing ring is positioned in U-lag.
Further, mounting flange and fuel tank upper box complete cycle seal weld.
Further, the upper end of mounting flange is provided with external screw thread, and the bottom of blind flange is provided with the female thread mated with this external screw thread.
In this programme, first sealing ring, the second sealing ring all can play sealing function, mounting flange also has certain sealing function with threadeding of blind flange, pass through multi-sealing structure, improve the sealing of fuel tank and oil pump installation place, can effectively reduce the amount of leakage of fuel tank and oil pump installation place fuel-steam.
It addition, U-lag by spacing for the first sealing ring wherein, it is to avoid first sealing ring displacement cause seal failure.Also mounting flange is fixed on fuel tank upper box by the way of complete cycle seal weld, adds the sealing of mounting structure.

Fig. 2 is partial structurtes schematic diagram of the present utility model；
Fig. 3 is vertical view design sketch of the present utility model.
Detailed description of the invention
The utility model will be further described with embodiment below in conjunction with the accompanying drawings.
A kind of fuel tank and the mounting structure of oil pump, as it is shown in figure 1, include having the fuel tank upper box 5 of perforate 52, the mounting flange 4 being fixed on perforate 52 periphery and the oil pump flange plate 2 coordinated with perforate 52.Oil pump flange plate 2 is arranged in the perforate 52 of fuel tank upper box 5, is provided with the first sealing ring 6 between oil pump flange plate 2 and fuel tank upper box 5.The edge part of oil pump flange plate 2 radially extends formation scrap (bridge) 21 after extending upward the centre bore of mounting flange 4, be provided with the second sealing ring 3 between the end face of scrap (bridge) 21 and mounting flange 4.Mounting flange 4 is threaded blind flange 1, blind flange 1 with mounting flange 4 screw thread rotation during, oil pump flange plate 2 is applied downward pressure, makes the first sealing ring 6 and the second sealing ring 3 in compressive state, it is achieved seal.
As in figure 2 it is shown, fuel tank upper box 5 is provided with the U-lag 51 of indent, U-lag 51 uses punch forming, and the first sealing ring 6 is positioned in U-lag 51.When oil pump is installed, first sealing ring 6 is positioned in U-lag 51, second sealing ring 3 is inserted in oil pump, oil pump flange plate 2 is installed in perforate 52, by blind flange, oil pump flange plate 2 is compressed with fuel tank upper box 5, make the first sealing ring 6 contact with fuel tank upper box 5, oil pump flange plate 2 and have certain decrement to keep sealing, make the second sealing ring 3 contact with mounting flange 4, oil pump flange plate 2 and have certain decrement to keep sealing.
Mounting flange 4 and fuel tank upper box 5 complete cycle seal weld, form weld part 42, to ensure sealing and fastness.
The upper end of mounting flange 4 is provided with external screw thread 41, and the bottom of blind flange 1 is provided with the female thread 12 mated with this external screw thread 41.As it is shown on figure 3, the upper surface of blind flange 1 is provided with the multiple blind flange perforates 11 being circumferentially distributed, it is used for connecting outside miscellaneous part.
