For achieving the above object, there is provided following technical scheme：A kind of valve guide bushing, including catheter body, the conduit sheet
Through hole is axially arranged with along which in vivo, the internal diameter of through hole is engaged with valve stem, and the surface of the through hole is provided with some storages
Oil groove, the outer surface of the catheter body are provided with boss, and the boss is provided with pouring orifice and is communicated with the oil storage tank, described lead
The outer wall of the two ends port of tube body is provided with outer tangent plane, and the inwall of one end port of the catheter body is provided with interior tangent plane, another
The inwall of port is provided with groove structure.
Preferably, the oil storage tank is uniformly distributed along the axial direction of the catheter body.
Preferably, the boss is loop configuration.
Preferably, the boss is provided with multiple pouring orifices.
Preferably, the boss is integrally formed with catheter body.
Preferably, the angle of inclination of the outer tangent plane is 15-30 degree.
Preferably, the angle of inclination of the interior tangent plane is 20-35 degree.
Preferably, the width of the groove structure for catheter body thickness 1/2.
The present invention provides a kind of having the beneficial effect that for valve guide bushing：The present invention is input into lubrication into oil storage tank by pouring orifice
Oil, the abrasion that valve stem is caused because of lack of lubrication between valve guide bushing when reducing cold start-up；Meanwhile, interior plande noodles are in back taper
Mesa-shaped, can store parts of lubricating oil, be conducive to forming film lubrication between valve guide bushing and valve stem, be easy to heat from valve stem
Conduct to cylinder head through valve guide bushing；Additionally, the wedge angle produced by groove structure inwall possesses scraping function, remove valve stem with
Coking and carbon distribution that valve guide bushing part has been formed, prevent inside its valve guide bushing of entering, and reduce valve guide bushing and valve stem
Abrasion, it is ensured that valve preferably can be moved back and forth.The present invention prevents valve stem from causing because of excessive wear with valve guide bushing
Gap is excessive, the phenomenon that burn oil and valve bond, and prevents lubricating oil excessive and enters combustion chambers burn, reduces engine oil consumption, change
Kind engine emission.

Specific embodiment
For making present disclosure more clear understandable, below in conjunction with Figure of description, present disclosure is made into one
Step explanation.The specific embodiment, the general replacement known to those skilled in the art the invention is not limited in certainly
Cover within the scope of the present invention.Secondly, the present invention has carried out detailed statement using schematic diagram, real the present invention is described in detail
During example, for convenience of description, schematic diagram, should not be in this, as limitation of the invention not according to general ratio partial enlargement.
Above and other technical characteristic and beneficial effect, by conjunction with the embodiments and accompanying drawing to the present invention valve guide bushing carry out
Describe in detail.Fig. 1 is the structural representation of the valve guide bushing preferred embodiment of the present invention.
As shown in figure 1, the present invention provides a kind of valve guide bushing, including catheter body 10, along its axial direction in catheter body 10
Through hole 20 is provided with, the internal diameter of through hole 20 is engaged with valve stem, the surface of through hole 20 is provided with some oil storage tanks 30, oil storage
Groove is uniformly distributed along the axial direction of catheter body.The outer surface of catheter body 10 is provided with boss 40, and boss 40 is provided with oiling
Mouth 50 is communicated with oil storage tank 30, and the present invention can pass through pouring orifice 50 to oiling in oil storage tank 30, valve stem when reducing cold start-up
The abrasion caused because of lack of lubrication between valve guide bushing.
Wherein, boss 40 is loop configuration, and boss 40 is provided with multiple pouring orifices 50, and boss 40 is preferred with catheter body 10
It is integrally formed.
Meanwhile, the outer wall of the two ends port of catheter body 10 is provided with outer tangent plane 60, and the angle of inclination of outer tangent plane 60 is 15-30
Degree.Outer tangent plane 60 overcomes machine oil and leaks into cylinder head burning interior by valve guide bushing outer wall, causes a large amount of carbon distributions, improves
