Detailed Description

The invention will be further explained with reference to the drawings and the specific embodiments.

Referring to fig. 2 and 3, a recyclable wall bushing centering positioner comprises an inner support 3, an outer support 4 and a support rod 5; the inner support 3 and the outer support 4 are of cambered surface structures respectively, the diameter of the inner support 3 is equivalent to the outer diameter of the pipeline 2, the diameter of the outer support 4 is equivalent to the inner diameter of the casing 1, so that the inner support 3 can be attached to the outer wall of the pipeline 2, and the outer support 4 can be attached to the inner wall of the casing 1; one or more support rods 5 are connected between the inner support 3 and the outer support 4 to form a positioner body; two or more than two locator bodies are arranged between the pipeline 2 and the sleeve 1 at intervals, so that the pipeline 2 and the sleeve 1 are coaxially arranged.

The inner supporting piece 3 is of a quarter circular arc structure, the outer supporting piece 4 is of a quarter circular arc structure, the specific size can be set according to different specifications of the pipeline 2 and the sleeve 1, the inner supporting piece 3 can be well attached to the outer wall of the pipeline 2, and the outer supporting piece 4 can be well attached to the inner wall of the sleeve 1. Preferably, four retainer bodies may be used to form the annular structure and surround the pipe 2, ensuring a central location of the pipe 2 within the casing 1.
