Abstract
The utility model discloses a kind of rotational moulding fuel tank, including main fuel tank, auxiliary fuel tank and the oil pipe of connection main fuel tank and auxiliary fuel tank, the oil pipe is realized with two fuel tanks by tubular metal inserts and is connected, if the outer surface for inlaying end of the metal insert is provided with, arterial highway anti-rotation is raised and if arterial highway annular groove, its connection end outer surface are provided with connection screw thread.The utility model is simple in construction, and the firm connection of metal insert and rotational moulding fuel tank can be achieved, prevent oil leak.
Description
Technical field
It the utility model is related to a kind of rotational moulding fuel tank.
Background technology
Fuel electric generator is a kind of small power generation equipment, and it generally includes oil-burning machine, generator, fuel tank and control system.
To adapt to different diesel-driven generator, the wildcard of fuel tank is realized, people are generally by the external fuel tank of tank design, and by external fuel tank
Main fuel tank and auxiliary fuel tank are set to, main fuel tank is used alone in selection as needed or major-minor fuel tank is used together, between major-minor fuel tank
Connected using oil pipe.Existing major-minor fuel tank generally use iron sheet makes, yielding, resistant to rust ability, easily leaks, because
And it is considered as rotational molding technique and prepares fuel tank.
However, tank body of oil tank is prepared using plastics, it is used for the joint of connected pipes and but still needed using metal material
Realize, because metal and plastics are two kinds of entirely different materials, common metal joint is embedded on the tank wall of plastic fuel tank easily
Loosen, gap is produced, so as to cause the leakage of fuel oil in casing.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of rotational moulding fuel tank.
To achieve the above object, the utility model uses following technical scheme：
A kind of rotational moulding fuel tank, including main fuel tank, auxiliary fuel tank and oil pipe, the main fuel tank are equipped with and its casing with auxiliary fuel tank
The tubular metal inserts of integral rotation molding, if inlaying for metal insert holds outer surface raised and some provided with arterial highway anti-rotation
Anti-rotation described in road ring cutting is raised and inlays the annular groove of end outer surface, and the connection end of metal insert is machined with connection screw thread, described
The joint at oil pipe both ends is threadedly coupled with the metal insert connection end on main fuel tank and auxiliary fuel tank respectively.
Preferably, the end of inlaying of metal insert is hexahedron, inlays that to be machined with the anti-rotation on 6 end faces at end convex
Rise.
Preferably, the quantity of the annular groove is 3.
Preferably, the groove width of the annular groove is 3-6mm.
Preferably, the groove width of the annular groove is 4mm, and the distance between any two adjacent annular groove is equal to annular groove
Groove width.
After adopting the above technical scheme, the utility model compared with background technology, has the following advantages that：It is raised by anti-rotation
With the setting of annular groove, loosening of the metal insert on rotational moulding casing tank wall is prevented, realizes the firm of metal insert and oil tank wall
Connection, occurs seepage when effectively preventing fuel oil from being conveyed between major-minor fuel tank.

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
Embodiment
As Figure 1-5, in the utility model embodiment, a kind of rotational moulding fuel tank, including main fuel tank 1, auxiliary fuel tank 2 and company
The oil pipe 3 of logical main fuel tank 1 and auxiliary fuel tank 2, the oil pipe 3 are realized and connected by tubular metal inserts 4 and two fuel tanks, to realize
The connection of major-minor fuel tank.Passage 11 and 12 is further respectively had on main fuel tank 1 and auxiliary fuel tank 2, is turned on and ventilated using connecting tube
Hole 11 and 12, you can make the gas intercommunication in major-minor fuel tank, fuel oil can be conveyed swimmingly between through oil pipe.Main fuel tank 1
On fuel oil adding mouth 12 be used for add fuel oil.
The end of inlaying of metal insert 4 is hexahedron, if its outer surface is provided with arterial highway anti-rotation projection 41 and ring cutting is prevented
Turn projection 41 and inlay the annular groove 42 of end outer surface.Form groove between adjacent anti-rotation projection 41, the groove of groove is to parallel
In the axis of metal insert 4, the outer surface of certain metal insert 4 can also be processed as annular knurl or other various concave/convex-shaped structures with for
For anti-rotation projection 41.
In the present embodiment, the A/F of each annular groove 42 is 4mm, and between two neighboring annular groove 42 away from
From being also 4mm.In addition, the quantity of annular groove 42 three is optimal, if too much because fuel tank wall thickness is certain, the meeting of metal insert 4 can not be complete
Complete embedded oil tank wall；The purpose of this utility model is then unable to reach very little.
The connection end of metal insert 4, its outer surface are then machined with connection screw thread 43, are realized by the mating connection of screw thread
The oil connection at the both ends of oil pipe 3 and being connected for metal insert 4.Sealing ring is provided with oil connection, prevents the seepage of fuel oil.
Above-mentioned metal insert 4 is embedded in mould, is integrally formed by rotational molding technique and fuel tank, makes metal insert 4
Connection end is exposed at outside fuel tank, is inlayed end and is embedded in oil tank wall.The annular groove 42 of metal insert 4 makes it anti-can draw in the axial direction
Drag；Be regular hexagon because inlaying end cross section, and its outer surface is provided with anti-rotation projection 41, thus its be likewise supplied with it is good antitorque
Turn performance, so can effectively ensure that the fastness that metal insert 4 is connected with fuel tank, prevent metal insert from releasing, cause fuel oil
Seepage.
It is described above, preferred embodiment only of the present utility model, but the scope of protection of the utility model is not limited to
This, any one skilled in the art is in the technical scope that the utility model discloses, the change that can readily occur in
Or replace, it should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should be with right
It is required that protection domain be defined.
