Description

Flange coupling connector

Technical field

The utility model belongs to flanged joint equipment technical field, is specifically a kind of flange coupling connector.

Background technology

Exhaust-driven turbo-charger exhaust-gas turbo charger and exhaust system downstream are often set in the exhaust system of Modern Internal-Combustion Engine.In bavin In the case of oil turbine, the air inlet of exhaust system is usually formed by catalytic converter, is in the case of gasoline engines The converter of grain filter.When assembling vehicle, these elements must be connected with each other.

This connection is generated usually using flanged joint, using the flanged joint by two flanged joints together, institute It states one in flange to be arranged in turbocharger, another is arranged on the air inlet of exhaust system.For this purpose, every Multiple holes are set in a flange, and having threaded screw or stud can be guided by the hole, and nut can be in the spiral shell It nails on and is tightened to be fixed.

These assemblings being threadedly coupled are complicated, because three for example all threaded connections manually will individually give birth to Production.In addition, the installation site of such flanged joint is generally difficult to or only partially reaches.This means need larger installation Space also has the significant depressions of peripheral parts sometimes.

The content of the invention

The utility model to solve the above-mentioned problems, provides a kind of flange coupling connector.

The utility model takes following technical scheme：A kind of flange coupling connector, including clamping stent I, clamping stent II, method Blue disk and pressure texture, the clamping stent I are equipped with edge ring I, and clamping has several flat position I on stent I, described It clamps stent II and is equipped with edge ring II, clamping stent II has several flat position II, flat position I and flat position II one by one Corresponding, clamping stent I and clamping stent II corresponding positions, which are equipped with, to be had threaded recess portion I and has threaded recess portion II, recessed Portion I and recess portion II composition screw holes, screw is equipped in screw hole, and screw is equipped with screw thread, screw end by being fixed with pressure texture, Ring flange, which is arranged on, to be clamped between stent I and clamping stent II, and ring flange is equipped with outside diminishing in-profile.

Further, pressure texture center is equipped with bolt hole, and pressure texture is equipped with V-arrangement and contacts surface.

Further, clamp stent I and clamp and be respectively equipped with two semicircular shells, semicircular shell on the outside of stent II Between be connected with web.

Compared with prior art, the utility model in this connection, the flange of turbocharger and the air inlet of exhaust system It is no longer directly screwed together, but is fixed to one another flange each other using stent is clamped, and it is in addition solid using screw support Determine and support each other.

Flanged joint is optimized for steric requirements closely, has small installation space and difficult assembling item Part.Component around flanged joint can be simpler to design, and assembling tool can also be simpler.Perpendicular to the list of flanged joint A most preferably accessible screw ensures preferably to assemble.In this case, diesel particulate filter catalytic converter or turn Free space cannot be omitted again by changing in device.

1- edge rings I, 2- ring flanges in figure, 3- clamp stent II, 4- and clamp the stent flat position I of I, 5-, 6- inner wheels Exterior feature, 7- screws, 8- screw threads, 9- recess portions II, 10- pressure texture, 11- bolts hole, 12-V shapes contact surface, 13- edge ring II, The flat position II of 14-, 15- semicircular shells, 16- webs, 17- recess portions I.

Specific embodiment

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work All other embodiments obtained shall fall within the protection scope of the present invention.

As shown in Figure 1, a kind of flange coupling connector, including clamping stent I4, clamping stent II3, ring flange 2 and pressure texture 10, the clamping stent I4 are equipped with edge ring I1, and clamping has several flat position I5, the clamping stent on stent I4 II3 is equipped with edge ring II13, and clamping stent II3 has several flat position II14, flat position I5 and flat position II14 mono- One corresponds to, and clamps stent I4 and has threaded recess portion I17 and the threaded recess portion of tool with clamping stent II3 corresponding positions and being equipped with II9, recess portion I17 and recess portion II9 form screw hole, are equipped with screw 7 in screw hole, and screw 7 is equipped with screw thread 8,7 end of screw by with Pressure texture 10 is fixed, and ring flange 2, which is arranged on, to be clamped between stent I4 and clamping stent II3, and ring flange 2 is equipped with outwards gradually contracting Small in-profile 6.

10 center of pressure texture is equipped with bolt hole 11, and pressure texture 10 is equipped with V-arrangement and contacts surface 12.

As shown in Figure 2,3, clamp stent I4 and clamp and be respectively equipped with two semicircular shells 15 on the outside of stent II3, half Web 16 is connected between circular shell 15.

Screw, which is located approximately midway in, to be clamped stent I and clamps in stent II and be approximately perpendicular to the bonding pad of flange Domain orients.Therefore, screw is in center oriented and perpendicular to the ring flange to be connected, therefore can reach and install well.For There is V-arrangement to contact surface, V-arrangement contact for the further fixation increased between screw support and flange, pressure texture Surface has the in-profile for the V-arrangement outer profile for being pressed against flange plate edge.Therefore the position of pressure texture is guaranteed.In addition, Flange utilizes its opposite exterior contour against each other.

Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art Say, can still modify to the technical solution recorded in foregoing embodiments or to which part technical characteristic into Row equivalent substitution, within the spirit and principle of the utility model, any modifications, equivalent replacements and improvements are made should all It is included within the scope of protection of this utility model.
