Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it is to be noted that the terms "mounted," "connected," and "connected" are to be construed broadly unless otherwise specifically indicated and limited. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1, 2 and 3, the pipe joint bearing assembly disclosed in this embodiment includes a positioning assembly 1 and a bearing member 2, and the bearing member 2 is installed outside the end face of the pipe joint 3 through the positioning assembly 1.

The positioning assembly 1 includes a telescoping assembly 11 and a liner 12.

Wherein the telescopic assembly 11 comprises an internally threaded tube 111 and a threaded rod 112. The internally threaded tube 111 is a circular tube, and has threads on its inner wall, and is bounded by its longitudinal center plane, with the threads at the two ends of its inner wall turning in opposite directions. The pair of screws 112 are respectively in threaded connection with two ends of the internal threaded pipe 111, and synchronous extension or recovery of the screws 112 at the two ends can be realized by rotating the internal threaded pipe 111. Meanwhile, in order to facilitate the rotation of the internally threaded pipe 111, a hexagonal prism 113 is arranged outside the middle of the internally threaded pipe 111 for facilitating the clamping of a wrench.

The inner linings 12 are arc-shaped angle steels and comprise axial sections and radial sections, a pair of inner linings are respectively connected outside the screw rods 112 through the axial sections, rubber rings 13 are arranged outside the axial sections to prevent the pipe joints 3 from being damaged, and a plurality of positioning bosses 14 are arranged outside the radial sections to facilitate installation of the pressure bearing parts 2. Meanwhile, in order to facilitate assembly and locking, the positioning boss 14 is arranged to be a truncated cone with a large outer part, a large inner part and a large outer part.

The pressure-bearing part 2 is designed into a circular ring, and a positioning hole is arranged on the entity of the pressure-bearing part corresponding to the positioning boss 14; the locating hole is the round hole that the aperture is greater than the diameter of location boss 14 outer end, and pressure-bearing part 2 and inside lining 12 realize the installation through locating hole and location boss 14, prevent that pressure-bearing part 2 from droing with tube coupling 3 when not atress.
