Be labeled as in figure: 1, pot lid, 11, deflation hole, 2, kettle body connecting portion, 3, packing seal, 31, seamless otch, 4, breather stem vent plug, 41, passage, 42, air extractor vent, 43, flange.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail.
The utility model vehicle oilcan structure, is mainly used on automobile gearbox, ensures ventilation, avoids leakage of oil.Comprise and be located at the kettle body connecting portion 2 that kettle body protrudes and the pot lid 1 be connected on kettle body connecting portion 2, pot lid 1 is provided with and is communicated with extraneous air gate 11, breather stem vent plug 4 is provided with in kettle body connecting portion 2, breather stem vent plug 4 axially extends the hollow cup-like structure of the degree of depth for having, breather stem vent plug 4 is provided with air extractor vent 42 and is communicated with by passage 41 with air gate 11; The upper surface of described kettle body connecting portion 2 is provided with common sheet-like gasket 3, has seamless otch 31 in the middle part of packing seal 3.This structure can ensure can the ventilation of kettle inside and outside, and has certain axial depth due to breather stem vent plug 4, splashes and plays certain buffer action, avoid fluid to sputter to fluid.
As shown in Figure 1, the oil can structure that the present embodiment provides mainly comprises with lower part, from outer to inner successively: pot lid 1, packing seal 3, breather stem vent plug 4.Wherein breather stem vent plug 4 is placed in kettle body, outstanding flange 43 is overlapped in the upper end of kettle body connecting portion 2, and packing seal 3 is placed on kettle body connecting portion 2 upper end, and is tightened on kettle body connecting portion 2 by pot lid 1, the outside wall surface of kettle body connecting portion 2 is provided with screw thread, and between pot lid 1 and this connecting portion, screw thread screws clamping.
Pot lid 1 has the air gate 11 of ventilation, for being threaded between pot lid 1 with kettle body connecting portion 2, packing seal 3 is pressed between the upper surface of pot lid 1 and kettle body connecting portion 2 by pot lid 1 to ensure to seal.Scratch a seamless otch in the middle part of packing seal 3, time inside and outside oil can without pressure reduction, otch is in normally off; When producing pressure reduction, otch pressurized is opened to realize ventilatory function automatically.Compare rubber pad traditional sense realizing ventilation sealing function, the rubber pad in the present invention is without the need to the complicated maze-type structure of row design again, and materials are few and reduce difficulty of processing and cost.
In the utility model, the wall of breather stem vent plug 4 can be the vertical wall extended straight down or the inclined wall inwardly shunk gradually, and inclined wall is more conducive to fluid and flows back to kettle body smoothly.The breather stem vent plug that the present embodiment provides is a columnar hollow cup-shaped structure, and bottom is obstructed, has certain axial depth, and middle part forms the passage 41 of ventilation, ensures that the fluid that the overwhelming majority is splashed is intercepted by breather stem vent plug 4 wall, can not touch upper end packing seal 3.Air extractor vent 42 for ventilation, and is opened sidewall locations bottom breather stem vent plug 4 and can be convenient to be back in kettle body for the fluid splashed in breather stem vent plug on a small quantity by air extractor vent 42, can be provided with well-distributed multiple, be conducive to better backflow.The upper end of breather stem vent plug 4 is provided with outstanding flange 43, structure in the form of annular discs, and kettle body connecting portion 2 upper surface is provided with the stepped hole of lap-joint flange 43.The degree of depth of stepped hole is equal to or less than the thickness of flange 43, ensures after tightening pot lid 1, and stable for breather stem vent plug 4 can be pressed abd fixed on kettle body connecting portion 2 by packing seal 3.Be movable overlap joint between flange 43 and kettle body connecting portion 2, be convenient to cleaning dismounting or change.
The utility model vehicle oilcan structure, in traditional sense, oil can structure is compared, and Each part of the present invention is simple, easy to process, simplifies the structure of packing seal 3 greatly, oil can structure is set up independently breather stem vent plug 4 structure, has and well keep off functional oil.Gas in kettle body is in communication with the outside by air extractor vent 42 and passage 41, to ensure ventilation, and breather stem vent plug 4 has certain degree of depth, certain buffer action is had to the fluid splashed, to avoid the direct attachment phenomenon of fluid splashed, thus avoid there is fluid in oil can exhaust process with the problem blowing out leakage of oil, well balance oil sealing and ventilation.Especially in the general vibration of automobile-used oil can and act on more obvious under rocking operating mode, significantly can intercept the fluid that constantly rolling is splashed, stop the generation of oil leakage phenomenon.This oil can enormously simplify structure, and make simple, cost is low, ensure that ventilation and oil sealing is effective, has stronger practicality.
By reference to the accompanying drawings the utility model is exemplarily described above; but the utility model is not limited to aforesaid way; as long as adopt method of the present utility model is conceived and technical scheme is carried out the improvement of various unsubstantialities or directly apply to other occasion, all drop in protection domain of the present utility model.
