[0020] like Figures 1 to 7As shown, a sealing sleeve type fastening bolt comprises a cylindrical main fastening connection column 1, a fastening combination thread groove is provided on the outer cylindrical surface of the main fastening connection column 1, and an integrally formed fastening stop matching column 2 is provided on the right end surface of the main fastening connection column 1. The projection of the fastening stop matching column 2 in the left and right directions is a regular hexagonal structure. When the overall fastening is performed, this position can be used in conjunction with a wrench-like tool for the overall fastening operation. Its left position is similar to the fastening bolt structure. An integrally formed cylindrical matching connection stabilizing column 3 is provided on the right side of the fastening stop matching column 2, and an integrally formed cylindrical matching sealing guide column 5 with a diameter smaller than that of the matching connection stabilizing column 3 is provided on the right side of the matching connection stabilizing column 3. A sealing matching safety groove 4 opening outward is provided between the right side of the matching connection stabilizing column 3 and the matching sealing guide column 5. This position is used in conjunction with a sealing ring during installation. The width of the outer position of the sealing matching safety groove 4 is greater than the width of the inner position. When installing, the end of the pipe component is inserted into this structural position for assembly. The right side of the said matching sealing guide column 5 is provided with a cylindrical center conveying matching hole 7 which completely penetrates the left side of the whole body, and the left center position of the said main body fastening connection column 1 is provided with a cylindrical conveying matching transition groove 8, which can ensure the smooth conveying matching of the internal fluid, and at the same time ensure the strength of the internal structure is more stable. It adopts a brand-new structural design, which is fastened to the mechanical components by means of fastening threads, and the other side is directly fitted with the pipe parts together with this product. The matching position is double-sealed by the sealing structure and the sealing ring, which ensures the sealing safety during matching.
