The following invention mainly describes the deflectable arbitrary angle part of the pipe connector in detail, and outlines the other parts in simple structure.
The front half body 1 and the rear half body 5 both comprise two connected pipe sections, and the two pipe sections are respectively a cylindrical barrel and a spherical barrel.
The spherical cylinder 1d of the front half body 1 is covered on the spherical cylinder 5b of the rear half body 5 and is arranged concentrically, so that the spherical cylinders of the front half body and the rear half body can rotate around a common sphere center. By adopting the scheme and the structure of matching two spherical surfaces, when the inner spherical barrel and the outer spherical barrel are concentric, the inner spherical barrel can rotate freely in the outer spherical barrel.
The opening terminal surface outside of the globular barrel 1d of first half section body 1 sets up first flange 1b, and a plurality of bolt holes 1e of equipartition on the terminal surface of first flange 1b can be connected with external pipe fitting through bolt assembly.

The opening end face of the spherical cylinder 1d of the first half body 1 is not parallel to the opening end face of the cylindrical cylinder 1a, but deflects by an angle, and the direction of the deflection angle is towards the direction close to the opening end face of the cylindrical cylinder 1 a.
Similarly, the axis of the opening end face of the spherical cylinder 5b of the rear half body 5 has an angle with the axis of the cylindrical cylinder thereof. The opening end face of the spherical cylinder 5b of the rear half body 5 is not parallel to the opening end face of the cylindrical cylinder, but deflects by an angle, and the direction of the deflection angle is towards the direction far away from the opening end face of the cylindrical cylinder.
As shown in fig. 2, since the spherical cylinder is disposed to be offset with respect to the cylindrical cylinder, it can be seen that the spherical cylinder 1d of the front half body 1 and the spherical cylinder 5b of the rear half body 5 are both long in one side wall and short in the other side wall.
The longer side walls of the spherical cylinder 1d of the front half body 1 and the spherical cylinder 5b of the rear half body 5 are overlapped, and the shorter side walls are overlapped, and the arrangement can enable the two spherical cylinder structures to be not limited when deflecting, so that the space is large enough and the deflection angle is maximized.

The inner spherical cylinder 5b of the rear half body 5 can be inserted into the outer spherical cylinder 1d of the front half body 1, and when the spherical centers of the two spherical cylinders are overlapped, the two spherical cylinders can rotate around the common spherical center. After the relative position of deflection between the front half body 1 and the rear half body 5 is adjusted, the bolt holes uniformly distributed on the end surfaces of the gland 4 and the first flange 1b are connected through the bolt assemblies, and the connecting and sealing effects are achieved. When the gland 4 is axially moved under the action of the bolt, the pressing ring 3 is respectively acted by axial force and radial force, the sealing ring 2 is compressed by the axial force, the pressing ring 3 is tightened by the radial force, and finally the function of sealing a connecting gap between the front half body 1 and the rear half body 5 is achieved.

The open end outside of the cylindrical barrel of half body 5 sets up second flange 5c, sets up a plurality of bolt holes 5d on second flange 5 c. A plurality of bolt holes are uniformly distributed on the end surfaces of the first flange 1b of the front half body 1 and the second flange 5c of the rear half body 5, and the bolt holes can be connected with an external connecting pipe through bolt components respectively.

Furthermore, the rubber seal ring is compressed and deformed by the rubber compression ring and the gland 4 to play a role of sealing the socket and spigot, and is kept fixed by the locking function of the gland 4.

When the deflection angles of the socket end face 1h and the socket end face 5g are zero, the existing market product technology is obtained.

In practical use, the proper deflection angle is adjusted to connect according to the site construction environment and geological conditions.
