In groove, the inside lateral bend formation end face seal bulb in interfacial seal circle whole body front end, the inner side of the interfacial seal circle is also
Provided with sealing lip, the cone structure with boss includes the conical surface and waterproof boss, and the waterproof boss is arranged on the conical surface
Big end, the end face seal bulb of the interfacial seal circle is closely enclosed in waterproof boss and hitch connector body housing end face shape
Into groove in, the sealing lip of the interfacial seal circle is close to the conical surface.
It is previously described for the novel sealing structure of rail traffic vehicles hitch connector, it is characterised in that：The sealing lip
The section on side is that class is triangular shaped, and drift angle is round-corner transition.
It is previously described for the novel sealing structure of rail traffic vehicles hitch connector, it is characterised in that：The waterproof is convex
The height of platform is higher than the highest point of the conical surface.
It is previously described for the novel sealing structure of rail traffic vehicles hitch connector, it is characterised in that：The conical surface is big,
The bending place of small end is round-corner transition.
The beneficial effects of the invention are as follows：The novel sealing structure for rail traffic vehicles hitch connector of the present invention,
Ensure that connector overall sealing performance is reliable and stable during the generation relative motion of the hitch of rail traffic vehicles two, while reducing interface
Sealing ring mechanical damage in use and abrasion, effectively increase the service life of interfacial seal circle, realize that three roads are close
Envelope, interfacial seal circle laminating is more preferable, and with waterproof boss, overall sealing performance is more reliable and more stable, installs before conical surface small end
Portion uses round-corner transition, it is to avoid interfacial seal circle is with installing mechanical damage during taper-face contact friction, and further extension makes
With the life-span, have a good application prospect.

Embodiment
Below in conjunction with Figure of description, the present invention is further illustrated.
The novel sealing structure for rail traffic vehicles hitch connector of the present invention, including it is assemblied in hitch connector
The interfacial seal circle 1 of plug casing end face, the cone structure 2 with boss positioned at hitch connector body housing forward end, such as Fig. 1
And shown in Fig. 2, the section of interfacial seal circle 1 is L shape, and the shirt rim of interfacial seal circle 1 is arranged on hitch connector plug housing
In the groove of end face, the inside lateral bend formation end face seal bulb 3 in the whole body front end of interfacial seal circle 1, the inner side of interfacial seal circle 1
Sealing lip 4 is additionally provided with, the section of sealing lip 4 is triangular shaped for class, and drift angle is round-corner transition, such as Fig. 3 and Fig. 4 institutes
Show, the cone structure 2 with boss includes the conical surface 5 and waterproof boss 6, the conical surface 5 is located at Socket casing front end face, described anti-
Water boss 6 is arranged on the big end of the conical surface 5, the end face seal bulb 3 of the interfacial seal circle 1 is close be enclosed in waterproof boss 6 with
In the groove of hitch connector body housing end face formation, the sealing lip 4 of interfacial seal circle 1 is close to the surface of the conical surface 5.
The height of the waterproof boss 6 is higher than the highest point of the conical surface 5, with waterproof boss 6, and overall sealing performance is more stablized
Reliably.
The bending place at the large and small end of the conical surface 5 is round-corner transition, it is to avoid when contacting friction with interfacial seal circle 1
Mechanical damage, reduces the abrasion condition during use, effectively raises the service life of interfacial seal circle 1.
The novel sealing structure for rail traffic vehicles hitch connector of the present invention, operation principle is as follows, works as track
When the hitch of vehicular traffic two is docked, in connector docking operation, as shown in Figures 5 and 6, the end face of interfacial seal circle 1 is close
Blocking first 3 contacts the conical surface 5 of the cone structure 2 with boss first, with the propulsion of deeply taking advantage of a situation plugged together, when end face seal bulb
3 pass through the high point of the conical surface 5（Waterproof boss 6）Low water afterwards（Waterproof boss 6 and the groove of hitch connector body housing end face formation
It is interior）, now the radial direction of end face seal bulb 3 be squeezed, form first of sealing, the then lip of the sealing lip 4 of interfacial seal circle 1
Side contacts the conical surface 5, is extruded by perpendicular to the direction of the conical surface 5 in progradation, now seals lip 4 and the extruding of the conical surface 5 and forms the
Two roads are sealed；The last first 3 contact hitch connector body housing end face of end face ball sealer simultaneously realizes extruding, now, interfacial seal
The end face seal bulb of circle 1 is compressed axially, and forms three seals.
The sealing property of hitch connector in the operating condition pass through the present invention sealing structure formation three seals and
One of waterproof boss realization, the schematic diagram after connection, as shown in Figure 7.
In summary, the novel sealing structure for rail traffic vehicles hitch connector of the invention, it is ensured that track is handed over
It is reliable and stable that connector overall sealing performance during relative motion occurs for two hitches of being open to traffic, while reducing interfacial seal circle makes
Mechanical damage and abrasion during, effectively increase the service life of interfacial seal circle, realize three seals, interfacial seal
Circle laminating is more preferable, and with waterproof boss, overall sealing performance is more reliable and more stable, and the big small end of the conical surface uses round-corner transition, keeps away
Mechanical damage when interfacial seal circle rubs with taper-face contact is exempted from, has further increased the service life, before good application
Scape.
