Description

Technical Field

[0001] The utility model relates to the technical field of oil cover sealing rings, in particular to an engine oil filling port cover with a sealing ring. Background Art

[0002] The engine is a machine that can convert other forms of energy into mechanical energy. The oil filler cap is one of the basic parts of the engine. When filling the engine with oil, the oil filler cap needs to be opened. At other times, the oil filler cap is sealed. A sealing ring is installed inside the oil filler cap to achieve the effect of sealing the oil filler cap.

[0003] At present, the oil filling port of most cars is sealed with a simple sealing ring. During the driving of the car, the sealing ring is likely to loosen due to vibration, so that gasoline may leak from the filling port and cause waste. Therefore, an oil filling port cap with a sealing ring is provided to solve the above problem. Utility Model Content

[0008] As a preferred technical solution of the utility model, a convex block is arranged at the inner lower end of the oil cap body, and the number of the convex blocks is four. The oil cap body is sleeved on the filling port.

[0009] As a preferred technical solution of the utility model, a slot is provided at the upper end of the filling port corresponding to the protrusion, and there are four slots. The oil cap body is clamped on the filling port through the protrusion.

[0010] As a preferred technical solution of the utility model, the first sealing ring is sealed inside the filling port, the second sealing ring is sealed at the top of the filling port, and a torsion bar is provided at the top of the oil cap body.

[0011] The utility model has the following advantages: the oil cap body can be fixed on the filling port by simply covering the oil cap body on the filling port, aligning the protrusion with the notch, pressing and rotating the oil cap body, and the oil cap body can be fixed on the filling port, which is convenient and quick;

[0012] After the oil cap body is covered on the filling port, the first sealing ring is squeezed and sealed inside the filling port. At the same time, the first sealing ring is located outside the circumference of the annular extrusion cavity and expands outward, so that the first sealing ring is more closely attached to the inner wall of the filling port, thereby improving the sealing effect. The second sealing ring can seal the top of the filling port again, thereby effectively avoiding oil leakage. The structure is simple, the operation is easy, and it is easy to use.

DETAILED DESCRIPTION

[0017] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] The utility model will be further described below in conjunction with the accompanying drawings.

[0020] Please refer to Figure 1-Figure 3 The utility model is an oil filling port cap with a sealing ring, comprising: an oil cap body 1, a sleeve 2 is fixedly connected to the inner side of the middle part of the oil cap body 1, a movable rod 3 is longitudinally movably connected to the inner wall of the sleeve 2, a bottom plate 4 is fixedly connected to the bottom end of the movable rod 3, a first sealing ring 5 is arranged at the bottom end of the bottom plate 4, an annular extrusion cavity 6 is opened inside the first sealing ring 5, a gasket 8 is longitudinally slidably sleeved on the inner side of the upper end of the oil cap body 1, and a second sealing ring 9 is arranged at the bottom end of the gasket 8.

[0021] Will combine Figure 3 As shown, the first sealing ring 5 and the second sealing ring 9 are both made of rubber, and the bottom plate 4 and the gasket 8 are both made of stainless steel, so as to ensure that the first sealing ring 5 and the second sealing ring 9 are subjected to the same longitudinal extrusion. A limiting column 7 is arranged in the middle of the bottom end of the bottom plate 4, and the limiting column 7 penetrates the first sealing ring 5. The cross section of the limiting column 7 is a T-shaped structure. The limiting column 7 can ensure that the first sealing ring 5 will not deviate. The first spring 201 is sleeved on the outer side of the circumference of the sleeve 2, and the second spring 10 is arranged between the inner side of the oil cover body 1 and the gasket 8. The downward elastic force of the second spring 10 can make the second sealing ring 9 contact the top end of the sealing filling port 13.

[0022] Combination Figure 2 As shown, a protrusion 11 is provided at the lower inner end of the oil cap body 1, and the number of protrusions 11 is set four. The oil cap body 1 is sleeved on the filling port 13. The upper end of the filling port 13 is provided with a groove 14 corresponding to the protrusion 11, and the number of grooves 14 is set four. The oil cap body 1 is clamped on the filling port 13 through the protrusion 11, the first sealing ring 5 is sealed inside the filling port 13, the second sealing ring 9 is sealed at the top of the filling port 13, and a torsion bar 12 is provided at the top of the oil cap body 1.

[0023] Specifically, when the utility model is used, it is only necessary to cover the oil cap body 1 on the filling port 13, and after aligning the protrusion 11 with the notch 14, press and rotate the oil cap body 1, and then the oil cap body 1 can be fixed on the filling port 13, which is convenient and quick. When the oil cap body 1 is covered on the filling port 13, the first sealing ring 5 is pushed downward by the first spring 201 all the time, so that the first sealing ring 5 is squeezed and sealed inside the filling port 13. At the same time, when the first sealing ring 5 is longitudinally squeezed, the annular extrusion cavity 6 in the first sealing ring 5 will be squeezed, so that the first sealing ring 5 located on one side of the annular extrusion cavity 6 expands outward, so that the first sealing ring 5 is more closely attached to the inner wall of the filling port 13, thereby improving the sealing effect. At the same time, the second sealing ring 9 can re-seal the top of the filling port 13, so that the oil port cover sealing ring has a good sealing effect, simple operation, and is easy to use.

[0024] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention.
