Utility model content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is: how to provide a kind of Residual oil to be utilized effectively, and improves the universal machine fuel tank of universal machine security performance.
In order to solve the problems of the technologies described above, the utility model have employed following technical scheme:
A kind of petrol engine oil tank, comprise casing, casing is provided with oil filler and oil-out, described bottom half is provided with the oil drain tank of outwardly convex, the sidewall of oil drain tank is communicated with described oil-out, and described box outer surface is provided with the support be connected with universal machine frame, and described support only has bolt mounting holes.
In the utility model, oil drain tank is for the minimum point of whole casing, in the process that gasoline levels falls under use, finally all can be gathered in oil drain tank, and oil drain tank is relative to casing, volume is little, sectional area is little, and gasoline will be better be utilized, and residual quantity reduced, simultaneously also because Residual oil reduces, improve the security performance of universal machine.
As optimization, described oil filler is provided with the fuel tank lid with oil filler threaded engagement, fuel tank lid is provided with falling-proof apparatus, falling-proof apparatus comprises chain-falling rope and bar shaped dop, the inner face of described fuel tank lid is provided with stud, one end of described chain-falling rope is provided with the nut with described stud threaded engagement, and the other end of described chain-falling rope is connected with the center of described bar shaped dop, and the length of described bar shaped dop is greater than the internal diameter of described oil filler.Bar shaped dop is put in casing, and the other end nut of chain-falling rope is arranged on the stud of fuel tank lid.When fuel tank cap open refuel in oil filler time, length due to bar shaped dop is greater than the internal diameter of oil filler, would not drop out in oil filler, and fuel tank cap will hang on fuel tank, after adding oil, just can directly oil filler be tightened by the fuel tank cap hung on fuel tank, prevent gasoline in fuel tank from exposing, improve security, also there will not be the situation that can not find fuel tank cap or fuel tank cap loss, the utility model structure is simple in addition, easy to use.
As optimization, described fuel tank lid also comprises enclosing cover and the inner cap with oil filler threaded engagement, described inner cap surface is provided with the annular protrusion centered by the described inner cap center of circle, is provided with annular groove between described annular protrusion and described inner cap, is provided with ring-shaped rubber sealing gasket in described annular groove.Be fixed in annular groove by ring-shaped rubber sealing gasket, when tightening fuel tank cap, the opening's edge of oil filler will prop up ring-shaped rubber sealing gasket, improves the sealing of fuel tank cap.
As optimization, the external side surface of described fuel tank cap is evenly distributed with multiple fins.Be convenient to turn fuel tank cap.
As optimization, the sidewall of described oil filler is provided with passage, and described passage is provided with the blast pipe to casing extension, is provided with the air inlet pipe be communicated with passage in described oil filler, and described air inlet pipe is connected with oil filler inwall is detachable.Air inlet pipe and blast pipe are set by the passage two ends respectively at oil filler sidewall, overcome the negative pressure in fuel tank, tank pressure balance can not only be kept with different temperature Change, oil can also be sent unobstructed to engine, guarantee the normal operation of engine.
As optimization, one end of described air inlet pipe is communicated with passage, and the other end of described air inlet pipe extends towards described oil filler port position.When some External Force Acting, gasoline in fuel tank can be caused to rock, the air inlet of air inlet pipe be extended towards oil filler port position direction, better avoids gasoline and leak out from passage.
As optimization, the outer surface of described air inlet pipe is provided with the fixture block of outwardly convex, and described oil filler inwall is provided with the draw-in groove be connected with described fixture block clamping.When passage blocks, air inlet pipe is taken apart, maintains easily.
In sum, the beneficial effects of the utility model are: the utility model structure is simple, Residual oil is utilized effectively, and improves universal machine security performance; Prevent fuel tank cap from losing, avoid the generation that can not find fuel tank cap or fuel tank cap loss situation, it also avoid because not having fuel tank cap to cause in fuel tank the time on gasoline in atmosphere exposed simultaneously, improve security; Overcome the negative pressure in fuel tank, tank pressure balance can not only be kept with different temperature Change, oil can also be sent unobstructed to engine, guarantee the normal operation of engine.
