In hydraulic system in vehicle, agricultural machinery or engineering machinery, through the hydraulic oil of return line backflow, in addition to having higher temperature (more than 100 DEG C), also there is higher return pressure, and with a large amount of bubbles.Life-time service is impacted by return pressure, at the atmospheric pressure interface such as the oil filler of hydraulic oil container or air vent, easily occurs punching press to leak.This is that existing hydraulic oil container generally exists and is difficult to the difficult problem overcome.
Summary of the invention
This utility model purpose is to provide the plastics hydraulic oil container of a kind of anti-oil return impact rotation molding, solves to impact the problem that leakage easily occurs at the atmospheric pressure interface such as oil filler or the air vent of hydraulic oil container because of return pressure.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of anti-oil return impact rotational moulding hydraulic oil tank structure, including a casing, this casing top is provided with oil return opening, oil filler and air vent, is provided with oil-out bottom it；Described oil return opening is opened on one end of box body wall, and described air vent and oil filler are provided with the other end of casing, and the diapire inner face of described casing is provided with a buffering boss, and described oil return opening is the most relative with buffering boss；Further, being provided with deflection plate by the side of one end that described box house sets air vent and oil filler at buffering boss towards casing, the lower edge of this lower deflection plate is connected with casing diapire, leaves gap between the sidewall corresponding with casing of its left edge and/or right edge.
In such scheme, described box house is additionally provided with deflection plate on, on this, deflection plate is positioned at air vent and oil filler towards by the side of the one end setting oil return opening on casing, and on this, the upper edge of deflection plate is connected with box top wall, leaves gap between the sidewall corresponding with casing of its left edge and/or right edge.
In such scheme, described oil filler is opened on the wall of casing, and is provided with a tubular body to box house extension downwards on oil filler.
The curved surfaces such as in such scheme, the surface of described buffering boss is spherical in shape, conical, polygonal pyramid shape.
This utility model, compared with the hydraulic oil container of existing steel (ferrum) sheet metal forming, has the advantage that
1, use rotational molding technique, seamless-molding of mould, non-leakage, be prone to processing；Change steel is plastics, and fuel tank processing cost is lower, more environmentally friendly；
2, devising buffering boss due to this utility model, buffering boss is the most right with oil return opening, makes to wash away in buffering boss from the oil return of the High Temperature High Pressure of oil return opening entrance, buffering boss has disperseed the pressure of oil return；And this utility model has also set time deflection plate; following deflection plate blocks directive air vent and the oil return of oil filler after the refraction of buffered boss; reduce return pressure further; thus finally protect at the atmospheric pressure interface such as oil filler and the air vent of hydraulic oil container; make at the atmospheric pressure interface such as oil filler and air vent of hydraulic oil container, to be not susceptible to impact leakage, extend service life.
3, it is also provided with upper deflection plate due to this utility model, upper deflection plate keeps off by oil filler and air vent, adds the refraction path of oil return, reduces return pressure further, the effect making reduction return pressure is more preferable, is less susceptible to leak at the atmospheric pressure interface such as the oil filler of hydraulic oil container and air vent.
4, being provided with a tubular body due to oil filler of the present utility model to box house extension, during use, the lower port of tubular body is in below the liquid level of hydraulic oil all the time, thus prevents oil return foam to enter oil filler.

Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is further described by embodiment:
Embodiment: see shown in Fig. 1-2:
The plastics hydraulic oil container of a kind of anti-oil return impact rotation molding, including a casing 1, this casing 1 top is provided with oil return opening 11, oil filler 12 and air vent 13, is provided with oil-out 14 bottom it.Fuel tank cap 122 it is covered with on described oil filler.
Shown in Figure 1, on the one end of the roof that described oil return opening 12 is opened in casing 1, and described air vent 13 and oil filler 12 are provided with the other end of casing 1, and the diapire inner face of described casing 1 is provided with a buffering boss 15, and described oil return opening 11 is relative with buffering boss about 15.
And, shown in Figure 1, it is provided with deflection plate 16 by the side of the internal one end setting air vent 13 and oil filler 11 at buffering boss 15 towards casing 1 of described casing 1, the lower edge of this lower deflection plate 16 is connected with casing 1 diapire, along between sidewall corresponding with casing 1, space is left on it, and leave gap 17 between the sidewall corresponding with casing 1 of its left edge and/or right edge, as shown in Figure 2.
Shown in Figure 1, described casing 1 is internal is additionally provided with deflection plate 18 on, on this, deflection plate 18 is positioned at air vent 13 and oil filler 12 towards by the side of the one end setting oil return opening 11 on casing 1, on this, the upper edge of deflection plate 18 is connected with casing 1 roof, it descends edge and leaves space between casing (1) corresponding sidewall, leaves gap 17 between the sidewall corresponding with casing 1 of its left edge and/or right edge.
Shown in Figure 1, described oil filler 12 is specifically opened on the roof of casing 1, and it is provided with a tubular body 121 to internal extension of casing 1 downwards on oil filler 12, in the lower port of tubular body 121 is in casing 1 all the time during use below the liquid level of hydraulic oil, thus oil return foam is prevented to enter oil filler 12.
Discharging hole 19 it is additionally provided with on the diapire of described casing.
During the present embodiment work; the oil return of High Temperature High Pressure enters from oil return opening; wash away on buffering boss 15; the pressure of oil return has been disperseed by buffering boss 15; then reflect on buffering boss 15; it is sputtered in lower deflection plate 16; return pressure is reduce further through the stop of lower deflection plate 16; it is sputtered in the most again on deflection plate 18; reduce return pressure further; thus finally protect at the atmospheric pressure interface such as oil filler and the air vent of hydraulic oil container, make to be not susceptible at the atmospheric pressure interface such as oil filler and air vent of hydraulic oil container leakage, extend service life.
Leave gap 17 between the sidewall corresponding with casing 1 of the left edge of described lower deflection plate 16 and/or right edge, refer to gap 17 is left on the left edge of lower deflection plate 16 or right edge between one or both and sidewall.
Leave gap 17 between the sidewall corresponding with casing 1 of the left edge of described upper deflection plate 18 and/or right edge, refer to gap 17 is left on the left edge of deflection plate 18 or right edge between one or both and sidewall.
If casing 1 length is longer, lower deflection plate 16 and upper deflection plate 18 all can set polylith so that the hydraulic oil of oil return successively through each lower deflection plate 16 and upper deflection plate 18 stop occur repeatedly reflect, further reduce pressure.
Lower deflection plate 16 and upper deflection plate 18 can be parallel to the wall of casing 1 and arrange, it is also possible to is obliquely installed.Fig. 1 and Fig. 2 is that citing descends deflection plate 16 and upper deflection plate 18 to arrange each parallel to left wall and the right wall of casing 1, in reality, can be obliquely installed completely, i.e. descend deflection plate 16 and upper deflection plate 18 in a certain angle with the left wall of casing and right wall, the direction of the inclination of lower deflection plate 16 and upper deflection plate 18 can be in the same direction, can also be reverse, all can play the effect of blood pressure lowering protecting against shock.
