Description

Oil rule for gasoline engine

Technical Field

The utility model relates to an oil level gauge, especially an oil level gauge for gasoline engine.

Background

At present, in order to detect the amount of oil in an engine of a gasoline engine, an oil level gauge is generally used as a detection device in an existing gasoline engine.

The existing oil rule mainly comprises an oil rule base, an oil rule cover and an oil rule scale connected with one end of the oil rule cover, wherein an O-shaped sealing ring is arranged at the lower part of the oil rule cover; the structure sealing surface of the oil rule is arranged on the large surface of the oil rule base, the contact area between the O-shaped ring and the oil rule base is large, and meanwhile, a limiting boss structure of a boss is arranged above the O-shaped ring. This kind of sealing mode has more problems: 1. when the oil level gauge is drawn, the oil level gauge is in contact with the limiting boss and excessively extruded, the phenomenon that the O-shaped ring is damaged can occur, and the risk of poor sealing and oil leakage exists after the O-shaped ring is damaged; 2. the O-shaped ring has a large sealing area, so that the oil level gauge has large friction force during drawing and is difficult to pull out, and the customer experience is influenced; 3. under the action of leak detection pressure, the reaction force borne by the oil rule is large, so that the oil rule cannot be sprayed out during leak detection, the lower limit value of the drawing force of the oil rule is large, the drawing force of the oil rule is not well controlled, and the use experience of a client is influenced; 4. more material is used and the cost is relatively higher.

The utility model discloses a utility model patent of title "a dipstick pipe assembly" is disclosed in CN204024766U, it includes the dipstick and with the pipe of oil storage chamber intercommunication, the pipe includes the inserted hole of dipstick and the pipe body of intercommunication with the oil storage chamber, the dipstick is including the sealing ring that is used for sealed pipe body, be connected with the transition pipe between inserted hole and the pipe body, the radius of transition pipe is greater than the radius of sealing ring. Although this structure can play sealed effect, the oil rule is when drawing, because the stroke overlength, the phenomenon that damages the sealing ring can appear in sealing ring and transition pipe contact and excessive extrusion, leads to having the risk of sealed good oil leak after the sealing ring damages, has reduced its sealed effect.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an effectively reduce the sealing ring and damage the risk, improve the oil rule that is used for the gasoline engine of sealed effect.

The utility model aims at realizing through the technical scheme, a fuel gauge for a gasoline engine, which comprises a fuel gauge base, a fuel gauge cover and a fuel gauge scale, wherein one end of the fuel gauge scale is connected with one end of the fuel gauge cover, an inclined step is arranged on the inner wall of the upper part of the fuel gauge base, and a straight line section is arranged below the inclined step; and a sealing ring is arranged on the outer wall of the lower part of the oil level gauge cover, and the sealing ring is in interference fit with the straight line section.

The oil rule cover comprises a cover body with a pull ring, a filling part is arranged on the lower end face of the cover body, the filling part is large in size and small in size, the diameter of the upper portion of the filling part is equal to or slightly smaller than the inner diameter of the upper portion of an oil rule base, the diameter of the lower portion of the filling part is slightly smaller than the inner diameter of a straight line segment, a sealing groove is formed in the outer wall of the lower portion of the filling part, and the sealing ring is located in the sealing groove.

Further, a flange A is arranged on the outer wall of the upper portion of the filling portion, a flange B is arranged on the inner wall of the upper portion of the oil level base, the filling portion is inserted into the oil level base, and the flange B is located above the flange A.

In order to improve the sealing effect between the oil level gauge seat and the gasoline engine, at least two O-shaped sealing rings are arranged on the outer wall of the lower part of the oil level gauge seat.

Since the technical scheme is used, the utility model has the advantages of simple structure, use reliably, low cost, adopt it not only to realize the facet is sealed, reduced the damage risk of sealing ring, the reaction force that the oil rule receives reduces by a wide margin under same leak hunting pressure moreover to the lower limit value of oil rule drawing force can be designed less, under the condition that satisfies pressure leak hunting, the drawing force of controlling the oil rule well promotes customer's use and experiences.
