Abstract
The utility model discloses a kind of steering oil pipes to connect pipe fitting, belong to the steering oil pipe connecting tube technical field of vehicle, it reduces and turns to oil circuit pipe fitting oil leak, improve full-vehicle steering system reliability, the steering oil pipe connects pipe fitting, and the escape of the left end bottom of thread of union nipple structure is a cone, the small change of a simple structure, the sealing effect that pipe fitting can be greatly improved reduces the risk of oil leak.
Description
Technical field
The utility model belongs to the steering oil pipe connecting tube technical field of vehicle, is related to a kind of steering oil pipe connecting tube and connects
Head.
Background technology
The steering oil pipe connection pipe joint structure used in heavy truck at present, when processing the bottom of thread all there are escape 1,
But the loose frame of red copper pad 2 is sleeved on push broach slot when this structure tightens pipe fitting, is easy oil leak herein.
The structure pipe fitting is as shown in Figure 1, 2, with the increase of (both ends) screwing force of pipe fitting, red copper pad 2 and cylinder
Gap is unable to control between body, leads to oil leak.
It is not difficult to find out from Fig. 1, this structure pipe fitting, red copper can not be made to pad 2 pairs of positive pressures on pipe fitting escape, seam
Gap is unable to control, and has the risk of oil leak.
Utility model content
The technical issues of the utility model solves is to provide a kind of steering oil pipe connection pipe fitting, reduces steering oil-way pipe and connects
Head oil leak, improves full-vehicle steering system reliability.
The technical solution of the utility model is：A kind of steering oil pipe connection pipe fitting, the left end screw thread of union nipple structure
The escape of bottom is a cone, and centrum right end diameter is more than left end, and the internal diameter of the right end diameter of cone and red copper pad is suitable,
On red copper cushion cover to escape, be attached on the right side of red copper pad on the left side plane of pipe fitting stage casing ontology, pipe fitting ontology it is straight
Diameter is more than the diameter of thread of pipe fitting left end, and pipe fitting stage casing ontology left and right ends are respectively left end screw thread and right end screw thread.
Preferably, red copper pad is annular.
Preferably, red copper pad and escape are clearance fit.
Preferably, the fit clearance of red copper pad and escape is 0.2mm.
Preferably, red copper pad can pass through the screw thread of pipe fitting escape left end.
Preferably, pipe fitting stage casing ontology is orthohexagonal.
Preferably, the right end diameter of cone is identical as the internal diameter of red copper pad.
The utility model has the advantage of the small change of a simple structure can greatly improve the sealing effect of pipe fitting
Fruit reduces the risk of oil leak.
Description of the drawings
Fig. 1 is the pipe joint structure figure in background technology；
Fig. 2 is the structure chart of the pipe fitting side view in background technology；
Fig. 3 is the structure chart of the pipe fitting of the utility model；
Fig. 4 is the structure chart of the side view of the pipe fitting of the utility model.
Specific implementation mode
The utility model is described in detail below.
Red copper pad is eccentric in order to prevent and oil leak, pipe fitting relief groove structure optimization design, in escape rear end machine again
The internal diameter of one cone of processing, cone distal end diameter and red copper pad is suitable, and clearance fit, gap 0.2mm may be used.
The structure avoids the problem that bias red copper pad and oil leak.Pipe joint structure is changed to structure as shown in Figure 3,4.
Because red copper pad 2 passes through the thread cylinder of pipe fitting left end to be set on escape, the right side of red copper pad 2 is attached to pipe fitting
On left side plane on hexagon body, red copper pad 2 passes through the threaded post of pipe fitting left end, the diameter in pipe fitting hexagon main body
More than the threaded post of pipe fitting left end.
Red copper pad 2 passes through the threaded post of pipe fitting left end, the diameter in pipe fitting hexagon main body big in the prior art
In the threaded post of pipe fitting left end, thus red copper pad 2 internal diameters can not change it is small, between red copper pads between 2 inner circumferentials and escape
Gap can not be eliminated.
The advantages of the utility model structure is：2 internal diameters, the steering of pipe fitting and left side are padded in the case that not changing red copper
When machine connection compresses, red copper pad 2 is located at the outer surface of cone on the right side of right side escape, under the guiding of the taper of cone, withdrawing
Slot is positioned directly in the radial middle position of pipe fitting, rises ensured between adapter and turning machine by red copper pad 2 well
Close joint effect, reduce the risk of oil leak.
By simply changing withdrawing groove shape in the utility model, so that it may to solve the problems, such as oil leak.In northern vehicle of running quickly
Above it was verified that effect is fine.
