Abstract
The utility model relates to an expanded oil cup cap. The lower side of an oil cap is appressed to be provided with an expanded plug, wherein a basin-shaped rubber cap at the inner layer and a basin-shaped rubber cap at the outer layer are buckled to form the expanded plug. A screw compressing device is respectively penetrated on the oil cap and the expanded plug. After the structure is adopted, the oil cup cap is directly covered on a seat of the oil cup cap, a screw is tightly screwed, the expanded plug which is axially compressed is expanded radially and the expanded plug is tightly appressed with the inner wall of the seat of the oil cup cap. The utility model has the advantages that the operation is simple, the effect on resisting shock is good, the seal is tight and the utility model can not be easily loosened. Rubber at the inner layer and rubber at the outer layer form a hollow rubber part, which leads the rubber to be easily expanded, and simultaneously, rubbery material is economized.
Description
Technical field
The utility model relates to a kind of tensioner oil cup cap.
Background technique
Adopt the screw threads for fastening cooperation between present oil cup cap and the lubricating cup cage, and in the locomotive high speed operation process, can produce sizable vibration, vibration can cause some to seal the loosening of positions, thereby the generation leakage that gets loose under long-term vibration is inevitable.Though some elastic plugs also can use, but cooperate not tightly, be easy to get loose, and real cored structure waste material very.
The model utility content
It is a kind of easy to use and reliable and save raw-material tensioner oil cup cap that the utility model purpose is to provide
To achieve these goals, the utility model adopts following technological scheme: a kind of tensioner oil cup cap, reclining at the oil cap downside is provided with the tensioner plug, and described tensioner plug is snapped together by the internal and external layer rubber cap of two basin shapes to be formed, and oil cap and tensioner are coated with spiral clamping device beyond the Great Wall.
Described spiral clamping device is by being applied in beyond the Great Wall screw of oil cap and tensioner, being fixedly installed on tensioner plug bottom surface and spinning and forming at nut on the screw and the handle that is fixedly installed on the screw in the oil cap outside.
Be abutted against on the described tensioner plug bottom surface and be provided with liner, the central position of tensioner plug and liner is run through in the screw lower end, and liner penetration hole place is fixed with the nut body supporting with screw.
The sealing edge of stretching out laterally that is provided with suitable for reading of described outer layer rubber cap, sealing is along leaning at oil cap along on the madial wall.
The screw in the described nut outside is provided with backing pin.
After having adopted this structure, oil cup cap is directly covered on the lubricating cup cage, by screwing screw,, tightly overlayed together with lubricating cup cage inwall to radially expanding by the tensioner plug of axial compression, simple to operate, the anti-vibration effect is better, seals sternlyer, is difficult for getting loose.Internal and external layer rubber is formed a hollow rubber part, makes rubber swelling easy, saves rubber material simultaneously greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Tensioner oil cup cap as shown in Figure 1, reclining at the oil cap downside is provided with the tensioner plug, and the tensioner plug is snapped together by the internal and external layer rubber cap 4,5 of two basin shapes to be formed, and oil cap 3 and tensioner are coated with spiral clamping device beyond the Great Wall.Outer layer rubber cap 5 suitable for reading is provided with the sealing of stretching out laterally along 9, and sealing leans at oil cap 3 along on the madial wall along 9,
Be abutted against on the tensioner plug bottom surface and be provided with liner 8, the central position of tensioner plug and liner 8 is run through in screw 2 lower ends, and liner 8 penetration hole places are fixed with the nut 7 supporting with screw 2.Coating adhesive is bonding between outer layer rubber cap 5 and the liner 8.Spiral clamping device is made up of the handle 1 that is applied in beyond the Great Wall screw 2 of oil cap 3 and tensioner, is fixedly installed on tensioner plug downside and is screwed in the nut 7 on the screw 2 and be fixedly installed on nut 7 outside screws 2.The screw 2 in nut 7 outsides is provided with backing pin 10, prevents that screw 2 from deviating from.
Also can on liner 8, open screw, screw directly and liner 8 be spirally connected.
Only need when using the tensioner oil cup cap is covered, and the handle 1 that turns clockwise, the inside and outside rubber cap 4,5 of compression, rubber swelling, tensioner lubricating cup cage, sealing and locking oil filler.About layer rubber is formed a hollow rubber part, makes rubber swelling easy, saves rubber material simultaneously.
The size that can change the tensioner oil cup cap as required adapts to the different lubricating cup of openings of sizes.
Claims (5)
1, a kind of tensioner oil cup cap is characterized in that: reclining at the oil cap downside is provided with the tensioner plug, and described tensioner plug is snapped together by the internal and external layer rubber cap of two basin shapes to be formed, and oil cap and tensioner are coated with spiral clamping device beyond the Great Wall.
2, tensioner oil cup cap according to claim 1 is characterized in that: described spiral clamping device is by being applied in beyond the Great Wall screw of oil cap and tensioner, being fixedly installed on tensioner plug bottom surface and spinning and forming at nut on the screw and the handle that is fixedly installed on the screw in the oil cap outside.
3, tensioner oil cup cap according to claim 2 is characterized in that: be abutted against on the described tensioner plug bottom surface and be provided with liner, the central position of tensioner plug and liner is run through in the screw lower end, and liner penetration hole place is fixed with the nut body supporting with screw.
