Description
Technical field
The present invention relates to a kind of fuel tank, be specifically related to a kind of universal machine fuel tank.
Background technique
The fuel tank of universal machine generally all can design oil outlet in the position of wall box near bottom, and casing is when consideration universal machine flying power, and usual tank capacity all can be larger, and the area of casing cross section is also corresponding larger.In the process that universal machine uses, in casing, the liquid level of gasoline declines gradually, when liquid level is lower than oil outlet, universal machine will quit work, and gasoline will remain in casing, although residual gasoline levels is lower, but because the volume of casing is large, section area is large, and residual amount of gasoline is relatively many, these Residual oils in casing cause waste, also can affect the Safety performance of universal machine.
Summary of the invention
For above-mentioned the deficiencies in the prior art, technical problem to be solved by this invention is: how to provide a kind of Residual oil to be utilized effectively, and improves the universal machine fuel tank of universal machine Safety performance.
In order to solve the problems of the technologies described above, present invention employs following technological scheme:
A kind of universal machine fuel tank, comprise casing, casing is provided with oil filler and oil outlet, and described bottom half is provided with the oil drain tank of outwardly convex, and the sidewall of oil drain tank is communicated with described oil outlet, and described box outer surface is provided with the support be connected with universal machine frame.
In the present invention, 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 Safety performance of universal machine.
As optimization, described oil filler is provided with the fuel tank lid with oil filler screw-thread fit, fuel tank lid is provided with falling-proof apparatus, falling-proof apparatus comprises chain-falling rope and bar shaped dop, the interior edge 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 screw-thread fit, 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, structure of the present invention is simple in addition, easy to use.
As optimization, described fuel tank lid also comprises enclosing cover and the inner cap with oil filler screw-thread fit, 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 vent, and described vent is provided with the outlet pipe to casing extension, is provided with the suction tude be communicated with vent in described oil filler, and described suction tude is connected with oil filler inwall is detachable.Suction tude and outlet pipe are set by the vent 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 motor, guarantee the normal operation of motor.
As optimization, one end of described suction tude is communicated with vent, and the other end of described suction tude extends towards described oil filler port position.When some External Force Acting, gasoline in fuel tank can be caused to rock, the suction port of suction tude be extended towards oil filler port position direction, better avoids gasoline and leak out from vent.
As optimization, the outer surface of described suction tude 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 vent blocks, suction tude is taken apart, maintains easily.
In sum, beneficial effect of the present invention is: structure of the present invention is simple, Residual oil is utilized effectively, and improves universal machine Safety 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 motor, guarantee the normal operation of motor.
