Abstract
The utility model discloses a kind of sealing structures of air brake hose nipple, including air brake hose nipple, bolt, clamp oil inlet, bolt mounting holes are set on the bracket, are mounted in mounting hole after being successively set with upper sealing washer, hose coupling, lower sealing washer on the bolt.Improved hose coupling will increase the groove of shape of threads in connector both ends of the surface, when bolt is tightened, red copper seal washer generates the shape for lugs opposite with thread shape under the action of screw-down torque, red copper seal washer seals the sealing structure that combines with face with foring linear sealing between hose coupling in this way, ensure that good contact.The oil leakage problem at hose coupling is efficiently solved, ensure that the brake efficiency of vehicle.
Description
Technical field
The utility model belongs to automotive field, and in particular to a kind of sealing structure of air brake hose nipple.
Background technique
It is the plane contact of the anchor ring and hose coupling by red copper seal washer before hose coupling structure improvement, passes through
What the cooperation in the screw-down torque of bolt and face and face was sealed, it is higher to the planarity requirements of hose coupling and copper washer,
If the guarantee of the flatness consistency of hose coupling and red copper seal washer is bad to be just relatively also easy to produce permeability phenomenon, vehicle is caused to be braked
Efficiency reduces.
Utility model content
The purpose of this utility model is to improve hose coupling connection type, solves hose coupling permeability and vehicle braking
The problem of efficiency reduces.
To achieve the above object, the utility model uses following technical scheme:
A kind of sealing structure of air brake hose nipple, including clamp described in air brake hose nipple, bolt, clamp oil inlet into
Bolt mounting holes are set on hydraulic fluid port, are mounted on after being successively set with upper sealing washer, hose coupling, lower sealing washer on the bolt
In mounting hole.
Further, the both ends of the hose coupling are provided with the groove of shape of threads, the upper sealing washer, lower seal pad
Circle cooperates assembly with reeded hose coupling.
Further, the groove at the both ends of the hose coupling is shape of threads, and the upper sealing washer, lower sealing washer are equal
It is assembled with cooperating with reeded hose coupling.
Further, the bolt is sealing bolt, and the sealing bolt includes the bolt method on bolt column and bolt column
It is blue.
Further, the bolt flange is circular ring shape.
Further, the seal washer is red copper seal washer.
Improved hose coupling will increase the groove of shape of threads, when bolt is tightened, red copper gasket in connector both ends of the surface
Enclose and generate the shape for lugs opposite with thread shape under the action of screw-down torque, such red copper seal washer and hose coupling it
Between stroke linear sealing with face seal the sealing structure combined, ensure that good contact.Effective solution hose connects
Oil leakage problem at head, ensure that the brake efficiency of vehicle.

Specific embodiment
The embodiment of the present invention is described in detail below in conjunction with attached drawing, but the present invention can be defined by the claims
Implement with the multitude of different ways of covering.
As shown in Figure 1 and Figure 2, a kind of sealing structure of air brake hose nipple 4, including air brake hose nipple 4, bolt 1, card
Oil inlet 6 is clamped, 1 mounting hole of bolt is set on the clamp oil inlet 6, is successively covered on the bolt 1 and loads onto red copper seal washer
3, it is mounted in mounting hole after hose coupling 4, lower red copper seal washer 5.The both ends of the hose coupling 4 are provided with shape of threads
Groove 7, after the groove 7 of shape of threads is arranged, upper red copper seal washer 3 and lower red copper seal washer 5 are under the action of screw-down torque
Generate the shape for lugs opposite with thread shape, stroke linear sealing and face are close between such red copper seal washer and hose coupling
The sealing structure combined is sealed, ensure that good contact, compared with being not provided with recessed grain, sealing performance is more preferable.It is described
Upper red copper seal washer 3, lower red copper seal washer 5, which cooperate with the hose coupling with groove 7, to be assembled, and the bolt 1 is sealing
Bolt 1, the sealing bolt 1 include the bolt flange 2 on 1 column of bolt column and bolt, and bolt flange 2 is circular ring shape.
These are only the preferred embodiment of the present invention, is not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.Any modification for all within the spirits and principles of the present invention, being made,
Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
