Abstract
The utility model relates to an automobile power steering oil pot sealing pad, which comprises a pad body, wherein the pad body is provided with three layers of stepped bosses sequentially comprising a top boss, a middle boss and a bottom boss from top to bottom; an arc-shaped groove is formed on the side wall of the middle boss; the center of the top boss is sunken inwards to form a column body; a through hole is formed at the bottom of the column body; and at least one vent hole is formed on the top boss. The oil pot sealing pad can obviously improve the sealing property of an oil pot, can discharge gas in a labyrinth annular air flue through the labyrinth annular air flue, can prevent oil from overflowing and prevent rainwater and steam from entering, and is simple in structure and convenient to assemble.
Description
Technical field
The utility model relates to the sealing material technical field, especially a kind of power steering oil pot of automobile sealing gasket.
Background technique
The at present oil-can lid of power steering oil pot of automobile commonly used or the not air flue of design ventilation, so that oil can can't exhaust, abnormal sound when causing motor turning, affect the operation portability of vehicle, although or have the air flue steering oil to overflow with air flue, simultaneously rain and dust enter oil can from air flue, cause automobile running to form the black dirt of oil immersion after a period of time around the oil-can lid, affect the turbidity test of automobile, cause certain potential safety hazard, cause easily oil-can lid poor aeration and oil impregnate.
The model utility content
The technical problems to be solved in the utility model is: for overcoming the problem of above-mentioned existence, provide a kind of good airproof performance, water proof and dust proof and can satisfy the power steering oil pot of automobile sealing gasket of ventilation requirement.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of oil can sealing gasket, comprise pad, described pad has three layers of cascade boss, be followed successively by from top to bottom top boss, middle boss and bottom boss, the boss sidewall has circular groove in the middle of described, boss center, described top caves inward into cylinder, and described cylinder bottom offers through hole, offers at least one vent on the boss of described top.
Further, the boss back side, described bottom is provided with the mazy type annular air channel, the gas that is trapped in the mazy type annular air channel can be discharged.
The beneficial effects of the utility model are, oil can sealing gasket of the present utility model not only can obviously improve the sealability of oil can, and can be with the gas discharge that is trapped in the mazy type annular air channel by the mazy type annular air channel, and can when stoping oil spill to go out, stop entering of rainwater and water vapour, simple in structure, easy for installation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is generalized section of the present utility model.
Fig. 2 is the utility model polycrystalline substance schematic representation.
1. top boss among the figure, the 1-1. vent, 2. in the middle of boss, 2-1. circular groove, 3. bottom boss, 3-1. mazy type annular air channel, 4. cylinder, 4-1. through hole.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Oil can sealing gasket as shown in Figure 1, comprise pad, pad has three layers of cascade boss, be followed successively by from top to bottom top boss 1, middle boss 2 and bottom boss 3, middle boss 2 sidewalls have circular groove 2-1, boss 1 center in top caves inward into cylinder 4, and cylinder 4 bottoms offer through hole 4-1, offers at least one vent 1-1 on the top boss 1.
As shown in Figure 2, boss 3 back sides in bottom are provided with mazy type annular air channel 3-1, the gas that is trapped in the mazy type annular air channel 3-1 can be discharged.
Oil can sealing gasket of the present utility model can prevent that rainwater and dust from advancing such as oil can from air flue, can satisfy ventilation requirement again simultaneously, can control destruction to the bubble that enters in the pad, thereby realizes sealing and preventing the effect of oil impregnate.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
