Abstract
The utility model discloses a guide pin, comprising a main body, compact heap and filter screen, the center of main part is equipped with the through -hole, the accessible through -hole is to the inside make -up gas of car turbocharger when the vacuum appearing in turbocharger, and the main part one end conical leading end that serves as reasons, the main part that is close to toper leading end is equipped with first ring body, the main part that is close to first ring body is equipped with the second ring body, the lateral surface of first ring body and second ring body is the circular conical surface, toper leading end, the central line of first ring body and second ring body is in on same the straight line, conical leading end's cross section radius is less than the cross section radius of first ring body, and the cross section radius of first ring body is less than the cross section radius of second ring body, has ensured that the vacuum pressure in the turbocharger can not make this guide pin take place deformation easily, and the main part other end is equipped with the screw thread, and the compact heap passes through the screw thread to be fixed the filter screen in the main part, has prevented that the large granule dust from getting into among turbocharger.
Description
Technical field
This utility model relates to the accessory of vehicle turbine supercharger, has particularly related to a kind of guide finger.
Background technology
Vehicle turbine supercharger in use, is by changing the gap size between blade and blade
Change air intake wind speed, but the size of the air intake vent of the tuyere of turbocharger be fixing, cause into
The air capacity entered there will be deficiency, vacuum occurs in making turbocharger, true when occurring in turbocharger
Time empty, the housing of turbocharger of long duration will be may result in leading of housing by extra pressure
Deform upon to pin, time serious, cause guide finger to cannot be carried out positioning, cause guide finger service life
Shorten.
Summary of the invention
This utility model provides a kind of guide finger, its objective is: be not susceptible to deformation, strengthens service life.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of guide finger, including main
Body, compact heap and drainage screen, the center of main body is provided with through hole, and main body one end is by cone guide end,
The main body being close to taper guide end is provided with the first ring body, and the main body being close to the first ring body is provided with the second ring
Body, the lateral surface of the first ring body and the second ring body is taper seat, taper guide end, the first ring body and
The centerline of two ring bodies is on same straight line；
The cross sectional radius of cone guide end is less than the cross sectional radius of the first ring body, the horizontal stroke of the first ring body
Section radius is less than the cross sectional radius of the second ring body；
The main body other end is provided with screw thread, and drainage screen is fixed in main body by compact heap by screw thread；
Main body between second ring body and screw thread is provided with annular protrusion, annular protrusion transversal
Radius surface is more than the cross sectional radius of the second ring body.
Relevant content in technique scheme is explained as follows:
Owing to technique scheme is used, this utility model compared with prior art has the advantage that
The center of main body is provided with through hole, can be by through hole to automobile whirlpool when occurring vacuum in turbocharger
Take turns the internal make-up gas of supercharger, and main body one end is by cone guide end, is close to taper and guides
The main body of end is provided with the first ring body, is close to the main body of the first ring body and is provided with the second ring body, the first ring body and
The lateral surface of the second ring body is taper seat, taper guide end, the first ring body and the centrage of the second ring body
Being on same straight line, the cross sectional radius of cone guide end is less than the cross section half of the first ring body
Footpath, the cross sectional radius of the first ring body is less than the cross sectional radius of the second ring body, it is ensured that turbocharger
Interior vacuum pressure will not make this guide finger deform upon easily, and the main body other end is provided with screw thread, compact heap
By screw thread, drainage screen is fixed in main body, it is therefore prevented that big dust particle enter turbocharger it
In.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of a kind of guide finger.
Wherein, 11. through hole 12. cone guide end 13. first ring body 14. second ring body 15. circle
Annular protrusion thing 2. compact heap 3. drainage screen.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the utility model is described in further detail:
As it is shown in figure 1, a kind of guide finger, including main body, compact heap 2 and drainage screen 3, in main body
The heart is provided with through hole 11, and main body one end is by cone guide end 12, is close to the master of taper guide end 12
Body is provided with the first ring body 13, and the main body being close to the first ring body 13 is provided with the second ring body 14, the first ring body
13 and second the lateral surface of ring body 14 be taper seat, taper guide end the 12, first ring body 13 and
The centerline of two ring bodies 14 is on same straight line, and the cross sectional radius of cone guide end 12 is less than
The cross sectional radius of the first ring body 13, the cross sectional radius of the first ring body 13 is less than the second ring body 14
Cross sectional radius, can be by through hole 11 to vehicle turbine supercharger when occurring vacuum in turbocharger
Internal make-up gas, it is ensured that the vacuum pressure in turbocharger will not make this guide finger generation shape easily
Become.
The main body other end is provided with screw thread, and drainage screen 3 is fixed in main body by compact heap 2 by screw thread, anti-
Stop big dust particle to enter among turbocharger.
Main body between second ring body 14 and screw thread is provided with annular protrusion 15, annular protrusion
The cross sectional radius of 15 is more than the cross sectional radius of the second ring body 14, and annular protrusion 15 serves
Good sealing function.
Above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow familiar
The personage of technique will appreciate that content of the present utility model and implements according to this, can not limit this with this
The protection domain of utility model.All equivalence changes made according to this utility model spirit or modification,
All should contain within protection domain of the present utility model.
