Utility model content
(problem to be solved in the utility model)
This utility model completes the most in view of the foregoing, its object is to, it is provided that a kind of metal system combustion
Hopper, for this fuel tank, not only corner is enhanced, and the accuracy of shape in corner is the highest.
(solving the scheme of problem)
Of the present utility model it is characterised by,
For metal fuel tank,
Have limiting part in the inside of described fuel tank, described limiting part limits the corner of described fuel tank
Internally side deformation,
At the section residing for described limiting part, described limiting part connects with whole described corners.
According to this utility model, it is possible to prevent internally side, corner from deforming by limiting part.I.e. by limiting
Parts make corner be enhanced.And, such as, at bending machining metallic plate thus when manufacturing fuel tank, by
Forming corner in bending metallic plate along the shape of limiting part, therefore, the shape in corner is accurate
Degree height.
And then, in this utility model, as preferably,
Described limiting part is tabular,
Whole edge of described limiting part connect with the inner peripheral surface of described section.
According to this structure, by limiting part, not only make the corner of fuel tank be enhanced, also make planar portions
It is enhanced.That is, fuel tank entirety is made to be enhanced.Further, owing to limiting part is tabular, therefore,
Simple in construction, it is easy to use, so that the assembling of fuel tank is more prone to.
And then, in this utility model, as preferably,
Described limiting part has intercommunicating pore.
When limiting part is tabular, restricting portion, the inside part of fuel tank is divided into multiple interval.
Here, according to said structure, fuel can be via intercommunicating pore through limiting part.Therefore, it is possible to
