Oil connection
Technical field
Present technique relates to oil connection, especially employed oil connection in the racing car.
Background technique
Racing car shakes big especially when match.Therefore high especially to the requirement of each component.For oil connection, have impact resistance preferably, not so can damage or come off from the connection block of fixed oil pipe joint.
Summary of the invention
The purpose of present technique provide a kind of can be shock-resistant, the oil connection that can not come off from connection block.
This oil connection comprises the fittings body with oily passage, and the periphery of fittings body is provided with collar.
The beneficial effect of present technique: collar embeds on the connection block during use, because collar can circumferentially shrink, so the collar that the concussion of connection block can be able to be shunk absorbs, has prevented that shock transfer is to fittings body.So this cylinder connector can be shock-resistant, can not come off from connection block easily.
If have only collar, collar can only absorb along the vibrations of collar radial direction, and for the vibrations of collar axial direction, collar can't absorb, and as further improving, above-mentioned oil connection also is provided with helical spring on the periphery of fittings body for this reason; The axial direction of helical spring axial direction and collar is perpendicular.Helical spring can absorb the vibrations of collar axial direction.Like this,, all can be absorbed, protect fittings body effectively in the vibrations of the radial and axial direction of collar.Best, the periphery of fittings body is provided with second annular groove, and helical spring is arranged in second annular groove, and helical spring periphery is greater than the fittings body periphery that has second annular groove.
Above-mentioned oil connection, the periphery of fittings body is provided with first annular groove, and collar is arranged in first annular groove, and the outer ring of collar is greater than the fittings body periphery that has first annular groove.
Above-mentioned oil connection, fittings body is processed with polytetrafluoroethylmaterial material.
Description of drawings
Fig. 1 is the schematic representation of present technique.
Fig. 2 is the unfolded drawing of collar.
Embodiment
Referring to oil connection shown in Figure 1, fittings body 1 is processed with polytetrafluoroethylmaterial material, and the center that comprises 3,6, two sections axle journals of two sections continuous axle journals is oily passage 2, on the periphery of the larger axis neck 3 of diameter, has first annular groove 4, and collar 5 is arranged in first annular groove.Collar is under open naturally state, and its outer ring is slightly larger than the periphery of axle journal 3.
The connecting part than pilot pin 6 and axle journal 3 at diameter has second annular groove 7, and spiral compression spring 8 is arranged in second annular groove, and the periphery of spiral compression spring is slightly larger than the periphery of axle journal 6.Fittings body 1 is coaxial with spiral compression spring, and the axial direction of spiral compression spring and the axial direction of collar are perpendicular.
Collar 5 belongs to existing technology, and it is a resilient ring body 52 with opening 51.Opening 51 dwindles, and ring body 52 just shrinks.Collar 5 can absorb collar vibrations radially, and spiral compression spring can absorb the axial vibrations of collar.
