Abstract
The invention relates to an engine cylinder cover oil filler structure. The engine cylinder cover oil filler structure comprises a cylinder cover oil filler, an oil filler cover and a sealing rubber ring, wherein the cylinder cover oil filler comprises a cylinder cover oil filler body; friction fitting surfaces are arranged in the cylinder cover oil filler body; two friction blocks fitting the friction filling surfaces are arranged at the lower part of the oil filler cover; locking stoppers and ending stoppers are respectively arranged on the friction fitting surfaces; the locking stoppers and the ending stoppers on the two friction fitting surfaces are distributed by 180 degrees; and a sealing rubber ring mounting groove is formed in the lower part of the oil filler cover. Through the friction between the friction blocks and the friction fitting surfaces and the limitation between the ending stoppers and the locking stoppers, the engine cylinder cover oil filler structure realizes a loose and falling prevention function of the oil filler cover, and has such characteristics as simple structure, convenience for operation and sealing performance.
Description
Technical field
The invention belongs to cylinder cover of engine hydraulic fluid port oil filler structure technical field, particularly relate to a kind of cylinder cover of engine oil filler structure.
Background technique
In engine operation process, due to the vibration of motor, causing coming off of cylinder head cover hydraulic fluid port filler cap, for preventing filler cap from coming off, need solve with special device.
Summary of the invention
The present invention for solve in known technology the technical problem that exists and provide a kind of structure simple, easy to install, efficiently solve filler cap loosen and come off, the cylinder cover of engine oil filler structure of good seal performance.
The technological scheme that the present invention takes for the technical problem existed in solution known technology is:
A kind of cylinder cover of engine oil filler structure, comprise cylinder head cover hydraulic fluid port, filler cap, sealing rubber ring, it is characterized in that: described cylinder head cover hydraulic fluid port comprises cylinder head cover hydraulic fluid port body, the inside of described cylinder head cover hydraulic fluid port body is provided with frictional fit face, the bottom of described filler cap is provided with two brake pads coordinated with frictional fit face, described frictional fit face is ramp structure, one end is little place, the other end is general goal, and the little place in this frictional fit face is less than the distance of brake pad upper surface to cylinder head cover hydraulic fluid port end face to the distance of cylinder head cover hydraulic fluid port end face; The general goal in described frictional fit face is greater than the distance of brake pad upper surface to cylinder head cover hydraulic fluid port end face to the distance of cylinder head cover hydraulic fluid port end face; Above-mentioned frictional fit face is respectively equipped with locking block and stops block; Locking block on two frictional fit faces and termination block are 180 ° of distributions, and the bottom of described filler cap is provided with sealing rubber ring mounting groove.
The present invention can also adopt following technical measures:
Described filler cap adopts fiberglass reinforced PP material to make.
The advantage that the present invention has and good effect are: because the present invention adopts technique scheme, by the friction in brake pad and frictional fit face, stop the spacing of block and locking projection, achieve the function of the locking Drop-proof of filler cap, there is the features such as structure is simple, easy to operate, sealability.
