Abstract

The utility model discloses a movable connector for an air pipe of a wagon. The movable connector comprises a sleeve with a shoulder, threads are arranged at one end of the sleeve with the shoulder, a circular shoulder protruded radially is arranged at the other end of the sleeve with the shoulder, and a sealing plane is arranged at the outer end face of the circular shoulder. The movable connector further comprises a sleeve, one end of the sleeve is provided with inner threads, the other end of the sleeve is provided with a radially-protruded shoulder with outer threads, and the outer end face with the outer threads is a sealing plane. The movable connector further comprises a lock nut, one end of the lock nut is provided with a locking ring protruded inwards, an inner cavity of the locking ring is matched with an outer wall of the sleeve with the shoulder, and the other end of the lock nut is provided with inner threads matched with the outer threads of the shoulder with the outer threads. The movable connector further comprises a sealing circular gasket matched with the sealing plane of the sleeve with the shoulder. By means of the movable connector, connection is convenient, sealing connection of the air pipe can be achieved by rotating the lock nut of the movable connector, installing is convenient, and maintaining is facilitated.

Description

A kind of railway freight-car airduct is used union
Technical field
The utility model relates to a kind of railway freight-car airduct and uses union.
Background technique
Railway freight-car airduct connection now generally connects with pipe collar, and this Placement must just can realize being tightly connected through rotating airduct, because installation environment is narrow, inconvenience not only is installed, and is unfavorable for maintenance, and the airduct structural design also is restricted.
The model utility content
Characteristics such as the technical problem that the utility model will solve provides a kind of railway freight-car airduct and uses union, and it has simple in structure, and is easy to use.
For solving the problems of the technologies described above, the technological scheme that the utility model is taked is: it comprises band shoulder sleeve pipe, and an end of band shoulder sleeve pipe is provided with internal thread, and the other end is provided with the circular convex shoulder of radial protrusion, and the exterior edge face of circular convex shoulder is provided with sealing plane; It also comprises sleeve pipe; One end of sleeve pipe is provided with internal thread, and the other end is provided with the band outside thread convex shoulder of radial protrusion, and the exterior edge face of band outside thread convex shoulder is a sealing plane; It also comprises locknut; One end of locknut is provided with inwardly protruded locking ring, and the inner chamber of locking ring is suitable with the outer wall of band shoulder sleeve pipe, and the other end of locknut is provided with and with the suitable internal thread of the outside thread of outside thread convex shoulder; It also comprises and the suitable sealing planchet in band shoulder bobbin seal plane.
The utility model further improves and is: the cross section external frame of band shoulder sleeve pipe and sleeve pipe is a regular hexagon, and orthohexagonal angle is a knuckle; Sealing plane inboard, circular convex shoulder outer end is provided with the snap ring of protrusion outward, and the external diameter of snap ring is less than the internal diameter of band outside thread convex shoulder outer end sealing plane, and suitable with the internal diameter of sealing planchet, its thickness is less than the thickness of sealing planchet.
Adopt the beneficial effect that technique scheme produced to be: the utility model can be realized being tightly connected of airduct through rotating the union locknut, and the rotation airduct that needs different from the past just can be realized being tightly connected, and the cross section external frame of band shoulder sleeve pipe and sleeve pipe is a regular hexagon; Orthohexagonal angle is a knuckle, and this kind design can be used the rotation of pipe wrench small angle when installation environment is comparatively narrow; Be very suitable for the installation environment of airduct on railway freight-car; The railway freight-car airduct adopts this union to connect, and is easy for installation, and is beneficial to maintenance; Can realize that the joint two ends are the requirement of crooked airduct, help the structural design of airduct.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the left view of Fig. 1.
In the accompanying drawings: 1, band shoulder sleeve pipe; 2, locknut; 3, sealing planchet; 4, sleeve pipe; 5, snap ring; 6, circular convex shoulder; 7, band outside thread convex shoulder; 8, locking ring.
Embodiment
Can be known that by the embodiment shown in Fig. 1-2 it comprises band shoulder sleeve pipe 1, an end of band shoulder sleeve pipe 1 is provided with internal thread, and the other end is provided with the circular convex shoulder 6 of radial protrusion, and the exterior edge face of circular convex shoulder 6 is provided with sealing plane; It also comprises sleeve pipe 4; One end of sleeve pipe 4 is provided with internal thread, and the other end is provided with the band outside thread convex shoulder 7 of radial protrusion, and the exterior edge face of band outside thread convex shoulder 7 is a sealing plane; It also comprises locknut 2; One end of locknut 2 is provided with inwardly protruded locking ring 8, and the inner chamber of locking ring 8 is suitable with the outer wall of band shoulder sleeve pipe 1, and the other end of locknut 2 is provided with and with the suitable internal thread of the outside thread of outside thread convex shoulder 7; It also comprises and the suitable sealing planchet 3 of band shoulder sleeve pipe 1 sealing plane; The cross section external frame of band shoulder sleeve pipe 1 and sleeve pipe 4 is a regular hexagon, and orthohexagonal angle is a knuckle; Sealing plane inboard, circular convex shoulder 6 outer end is provided with the snap ring 5 of protrusion outward, and the external diameter of snap ring 5 is less than the internal diameter of band outside thread convex shoulder 7 outer end sealing planes, and suitable with the internal diameter of sealing planchet 3, its thickness is less than the thickness of sealing planchet 3.
Method for using:
The airduct two ends that needs are connected are connected with bobbin seal with band shoulder sleeve pipe respectively; To be with shoulder sleeve pipe and sleeve pipe locking through locknut then; Owing to be provided with sealing plane between band shoulder sleeve pipe and the sleeve pipe; And be added with sealing gasket, so locking the time can realize being tightly connected between the airduct, the whole operation process need not to rotate airduct and can realize being tightly connected.
